Audience
This command reference is intended for administrators who want to use the command-line interface
(CLI) of the Wide Area Application Services (WAAS) software to configure, manage, and monitor
WAAS devices on a per-device basis. This guide assumes that the WAAS device is running the WAAS
software. The guide provides descriptions and syntax of the WAAS CLI command.
The WAAS CLI allows you to configure, manage, and monitor WAAS devices on a per-device basis
through a console connection or a terminal emulation program. The WAAS CLI also allows you to
configure certain features that are only supported through the WAAS CLI (for example, configuring
LDAP signing on a WAE).
The instructions and examples in this guide describe only those features that can be configured on an
individual WAAS device using the WAAS CLI.
In addition to the WAAS CLI, there are three WAAS graphical user interfaces (GUIs) that you access
from your browser:
•
Note
The WAAS Central Manager GUI allows you to centrally configure, manage, and monitor a WAE
or group of WAEs that are registered with the WAAS Central Manager. You also use this GUI to
configure, manage, and monitor the WAAS Central Manager, which is the dedicated appliance on
which the WAAS Central Manager GUI is running.
When you use the WAAS Central Manager GUI, you have the added capability of centrally configuring
settings and policies for groups of WAEs (device groups). When you use the WAAS CLI, you can only
configure settings and policies on a per-device basis.

Preface
•
The WAE Device Manager GUI allows you to remotely configure, manage, and monitor an
individual WAE through your browser. In many cases, the same device settings can be found in both
the WAE Device Manager GUI and the WAAS Central Manager GUI. For this reason, we strongly
recommend that you always configure a WAE from the WAAS Central Manager GUI whenever
possible.
•
The WAAS Print Services Administration GUI allows you to remotely configure an individual
WAAS print server and view a list of active and completed print jobs. You can access the WAAS
Print Services Administration GUI from either the WAAS Central Manager GUI or the WAE Device
Manager GUI.
The WAAS GUIs are the primary resources for configuration and monitoring WAEs. We strongly
recommend that you use the WAAS Central Manager GUI instead of the WAAS CLI, whenever
possible. For more information about how to use the WAAS GUIs to configure, manage, and monitor
your WAAS devices, see the Cisco Wide Area Application Services Configuration Guide.
We recommend that you be familiar with the basic concepts and terminology used in internetworking,
in your network topology, and in the protocols that the devices in your network can use. We also
recommend that you have a working knowledge of the operating systems on which you are running your
WAAS network, such as Microsoft Windows, Linux, or Solaris. This guide is not a tutorial.

Using the WAAS Command-Line Interface
The Cisco WAAS software command-line interface (CLI) is used in combination with the WAAS
Manager GUI to configure, monitor, and maintain a WAAS device. The CLI on a WAAS device can be
accessed directly through the console port of an attached PC or remotely through a Telnet session on a
PC running terminal emulation software.
Note
The WAAS software runs on the WAE-511, WAE-512, WAE-611, WAE-612, WAE-7326. WAE-7341,
and WAE-7371. You must deploy the WAAS Central Manager on a dedicated appliance.
Throughout this book, the term WAE is used to refer collectively to the supported WAE platforms unless
otherwise noted. For simplification, the term WAAS device is used to refer collectively to WAAS Central
Managers and WAEs that are running the WAAS software.
This chapter provides an overview of how to use the WAAS CLI, including an explanation of CLI
command modes, navigation and editing features, and help features.

Using the WAAS Command-Line Interface
Using Command Modes
Using Command Modes
The CLI for WAAS software is similar to the CLI for Cisco IOS software. Like Cisco IOS software, the
WAAS CLI is organized into different command and configuration modes. Each mode provides access
to a specific set of commands. This section describes the command modes provided by the WAAS
software CLI and includes the following topics:
•
Organization of the WAAS CLI, page 1-2
•
Using EXEC Mode, page 1-3
•
Using Global Configuration Mode, page 1-3
•
Using the Interface Configuration Mode, page 1-4
•
Using ACL Configuration Modes, page 1-5
•
Command Modes Summary, page 1-5
•
Device Mode, page 1-6
Organization of the WAAS CLI
The WAAS software CLI is organized into multiple command modes. Each command mode has its own
set of commands to use for the configuration, maintenance, and monitoring of a WAAS WAE. The
commands available to you at any given time depend on the mode you are in. Entering a question mark
(?) at the system prompt allows you to obtain a list of commands available for each command mode.
The WAAS command modes include the following:
•
EXEC mode—For setting, viewing, and testing system operations. This mode is divided into two
access levels: user and privileged. To use the privileged access level, enter the enable command at
the user access level prompt, and then enter the privileged EXEC password when you see the
password prompt.
•
Global configuration mode—For setting, viewing, and testing configuration of WAAS software
features for the entire device. To use this mode, enter the configure command from privileged EXEC
mode.
•
Interface configuration mode—For setting, viewing, and testing the configuration of a specific
interface. To use this mode, enter the interface command from global configuration mode.
•
Standard ACL configuration mode—For creating and modifying standard access lists on a WAAS
device for controlling access to interfaces or applications. To use this mode, enter the ip access-list
standard command from global configuration mode.
•
Extended ACL configuration mode—For creating and modifying extended access lists on a WAAS
device for controlling access to interfaces or applications. To use this mode, enter the ip access-list
extended command.
Use specific commands to navigate from one command mode to another. Use this standard order to
access the modes: user EXEC mode, privileged EXEC mode, global configuration mode, interface
configuration mode, standard ACL configuration mode, or extended ACL configuration mode.

Chapter 1
Using the WAAS Command-Line Interface
Using Command Modes
Using EXEC Mode
Use the EXEC mode for setting, viewing, and testing system operations. In general, the user EXEC
commands allow you to connect to remote devices, change terminal line settings on a temporary basis,
perform basic tests, and list system information.
The EXEC mode is divided into two access levels: user and privileged. The user EXEC mode is used by
local and general system administrators, while the privileged EXEC mode is used by the root
administrator. Use the enable and disable commands to switch between the two levels. Access to the
user-level EXEC command line requires a valid password. The user-level EXEC commands are a subset
of the privileged-level EXEC commands. The user-level EXEC prompt is the hostname followed by a
right angle bracket (>). You can change the hostname using the hostname global configuration
command. The prompt for the privileged-level EXEC command line is the pound sign (#). To execute an
EXEC command, enter the command at the EXEC system prompt and press the Return key. In the
following example, a user accesses the privileged-level EXEC command line from the user level:
WAE> enable
WAE#
Use the Delete or Backspace key sequences to edit commands when you enter commands at the EXEC
prompt.
Most EXEC mode commands are one-time commands, such as show or more commands, which show
the current configuration status, and clear commands, which clear counters or interfaces. EXEC mode
commands are not saved across reboots of the WAE.
As a shortcut, you can abbreviate commands to the fewest letters that make them unique. For example,
the letters sho can be entered for the show command.
Certain EXEC commands display multiple screens with the following prompt at the bottom of the
screen:
--More--
Press the Spacebar to continue the output, or press Return to display the next line. Press any other key
to return to the prompt. Also, at the --More-- prompt, you can enter a ? to display the help message.
To leave EXEC mode, use the exit command at the system prompt:
WAE# exit
WAE>
The EXEC commands are entered in EXEC mode.
Using Global Configuration Mode
Use global configuration mode for setting, viewing, and testing configuration of WAAS software
features for the entire device. To enter this mode, enter the configure command from privileged EXEC
mode. The prompt for global configuration mode consists of the hostname of the WAE followed by
(config) and the pound sign (#). You must be in global configuration mode to enter global configuration
commands.
WAE# configure
WAE(config)#

Using the WAAS Command-Line Interface
Using Command Modes
Commands entered in global configuration mode update the running configuration file as soon as they
are entered. These changes are not saved into the startup configuration file until you enter the copy
running-config startup-config EXEC mode command. See the “Saving Configuration Changes”
section on page 1-9. Once the configuration is saved, it is maintained across WAE reboots.
You also can use global configuration mode to enter specific configuration modes. From global
configuration mode you can enter the interface configuration mode, standard ACL configuration mode,
or the extended ACL configuration mode.
From configuration modes, you can enter configuration submodes. Configuration submodes are used for
the configuration of specific features within the scope of a given configuration mode. As an example,
this chapter describes the subinterface configuration mode, a submode of the interface configuration
mode.
To exit global configuration mode, use the end global configuration command:
WAE(config)# end
WAE#
You can also exit global configuration mode by entering the exit command or by pressing Ctrl-Z.
Global configuration commands are entered in global configuration mode.
Configuration changes that you make in global configuration mode on a WAE are propagated to the
Centralized Management System (CMS) database on the WAAS Central Manager. CLI changes are sent
to the Central Manager after you exit out of configuration mode, or if all configuration mode sessions
have been inactive for 10 minutes.
Using the Interface Configuration Mode
Use the interface configuration mode for setting, viewing, and testing the configuration of WAAS
software features on a specific interface. To enter this mode, enter the interface command from the
global configuration mode. The following example demonstrates how to enter interface configuration
mode:
WAE# configure
WAE(config)# interface ?
GigabitEthernet Select a gigabit ethernet interface to configure
InlineGroup
Select an inline group interface to configure
InlinePort
Select an inline port interface to configure

WAE(config)# interface gigabitethernet ?
<1-2>/ GigabitEthernet slot/port
WAE(config)# interface gigabitethernet 1/0
WAE(config-if)#
To exit interface configuration mode, enter exit to return to global configuration mode:
WAE(config-if)# exit
WAE(config)#
The interface configuration commands are entered in interface configuration mode.

Using the WAAS Command-Line Interface
Using Command Modes
Device Mode
The WAAS software provides the ability to specify the device mode of a WAAS device. In a WAAS
network, you must deploy a WAAS device in one of the following device modes:
•
Central Manager mode—Mode that the WAAS Central Manager device needs to use.
•
Application accelerator mode—Mode for a WAAS Accelerator (that is a Core WAE or Edge WAE)
that is running the WAAS software. WAEs are used to optimize TCP traffic over your network.
When client and server applications attempt to communicate with each other, the network intercepts
and redirects this traffic to the WAEs so that they can act on behalf of the client application and the
destination server. The WAEs examine the traffic and use built-in application policies to determine
whether to optimize the traffic or allow it to pass through your network unoptimized.
The default device mode for a WAAS device is application accelerator mode. The device mode global
configuration command allows you to change the device mode of a WAAS device.
waas-cm(config)# device mode ?
application-accelerator Configure device to function as a WAAS Engine.
central-manager
Configure device to function as a WAAS Central Manager.
For example, after you use the WAAS CLI to specify the basic network parameters for the designated
WAAS Central Manager (the WAAS device named waas-cm) and assign it as a primary interface, you
can use the device mode configuration command to specify its device mode as central-manager.
waas-cm# configure
waas-cm(config)#
waas-cm(config)# primary-interface gigabitEthernet 1/0
waas-cm(config)# device mode central-manager
waas-cm(config)# exit
waas-cm# copy run start
waas-cm# reload
Proceed with reload?[confirm] y
Shutting down all services, will Reload requested by CLI@ttyS0.
Restarting system.
To display the current mode that the WAAS device is operating in, enter the show device-mode current
EXEC command:
WAE# show device-mode current
Current device mode: application-accelerator
To display the configured device mode that has not taken effect, enter the show device-mode configured
EXEC command. For example, if you had entered the device mode central-manager global
configuration command on a WAAS device to change its device mode to central manager but have not
entered the copy run start EXEC command to save the running configuration on the device, then if you
were to enter the show device-mode configured command on the WAAS device, the command output
would indicate that the configured device mode is central-manager:
WAE# show device-mode configured
Configured device mode: central-manager
Because WAAS Central Manager must be deployed on a dedicated appliance, a WAAS device can
operate only in one device mode: either in central-manager mode or application-accelerator mode.
The set of WAAS CLI commands that are available vary based on the device mode of the WAAS device.

Cisco WAAS Software Command Summary
This chapter summarizes the Cisco WAAS 4.0.7 software commands.
Table 2-1 lists the WAAS commands (alphabetically) and indicates the command mode for each
command. The commands used to access configuration modes are marked with an asterisk. Commands that
do not indicate a particular mode are EXEC mode commands. The same command may have different
effects when entered in a different command mode, so they are listed and documented separately. (See
Chapter 1, “Using the WAAS Command-Line Interface” for a discussion about using CLI command
modes.)
In Table 2-1, in the Device Mode column “All” indicates that the particular CLI command is supported
in both central manager mode and application accelerator mode.
Note
When viewing this reference online, click the name of the command in the left column of the table to
jump to the command page, which provides the command syntax, examples, and usage guidelines.
Throughout this book, the term WAAS device refers collectively to a WAAS Central Manager and a
WAE. The term WAE refers collectively to the supported WAE platforms that are running the WAAS
software.

Chapter 3 CLI Commands
EXEC Mode Commands
Use the EXEC mode for setting, viewing, and testing system operations. In general, the user EXEC
commands allow you to connect to remote devices, change terminal line settings on a temporary basis,
perform basic tests, and list system information.
The EXEC mode is divided into two access levels: user and privileged.
The user EXEC mode is used by local and general system administrators, while the privileged EXEC
mode is used by the root administrator. Use the enable and disable commands to switch between the two
levels. Access to the user-level EXEC command line requires a valid password.
The user-level EXEC commands are a subset of the privileged-level EXEC commands. The user-level
EXEC prompt is the hostname followed by a right angle bracket (>). The prompt for the privileged-level
EXEC command line is the pound sign (#). To execute an EXEC command, enter the command at the
EXEC system prompt and press the Return key.
Note
You can change the hostname using the hostname global configuration command.
In the following example, a user accesses the privileged-level EXEC command line from the user level:
WAE> enable
WAE#
To leave EXEC mode, use the exit command at the system prompt:
WAE# exit
WAE>

Usage Guidelines
After you use the clear cache dre command, the first 1 MB of data is not optimized. Cisco WAAS does
not optimize the first 1 MB of data after a restart of the tcpproxy service. Data transmitted after the first
1 MB of data will be optimized according to the configured policy.
The clear logging command removes all current entries from the syslog.txt file, but does not make an
archive of the file. It puts a “Syslog cleared” message in the syslog.txt file to indicate that the syslog has
been cleared, as shown in the following example.
Feb 14 12:17:18 WAE# exec_clear_logging:Syslog cleared
The clear statistics command clears all statistical counters from the parameters given. Use this
command to monitor fresh statistical data for some or all features without losing cached objects or
configurations.
The clear users administrative command clears the connections for all administrative users who are
authenticated through a remote login service, such as TACACS. This command does not affect an
administrative user who is authenticated through the local database.
The clear windows-domain-log command removes all current entries from the Windows domain log
file.

Usage Guidelines
If you have an outside source on your network that provides time services (such as a NTP server), you
do not need to set the system clock manually. When setting the clock, enter the local time. The WAAS
device calculates the UTC based on the time zone set by the clock timezone global configuration
command.
Two clocks exist in the system: the software clock and the hardware clock. The software uses the
software clock. The hardware clock is used only at bootup to initialize the software clock.
The set keyword sets the software clock.
Examples
The following example sets the software clock on the WAAS device:
WAE# clock set 13:32:00 01 February 2005

Device Modes
application-accelerator
central-manager
Usage Guidelines
The WAAS network is a collection of WAAS device and WAAS Central Manager nodes. One primary
WAAS Central Manager retains the WAAS network settings and provides other WAAS network nodes
with updates. Communication between nodes occurs over secure channels using the Secure Shell Layer
(SSL) protocol, where each node on the WAAS network uses a Rivest, Shamir, Adelman (RSA)
certificate-key pair to communicate with other nodes.
Use the cms config-sync command to enable registered WAAS devices and standby WAAS Central
Manager to contact the primary WAAS Central Manager immediately for a getUpdate (get configuration
poll) request before the default polling interval of 5 minutes. For example, when a node is registered with
the primary WAAS Central Manager and activated, it appears as Pending in the WAAS Central Manager
GUI until it sends a getUpdate request. The cms config-sync command causes the registered node to
send a getUpdate request at once, and the status of the node changes as Online.
Use the cms database create command to initialize the CMS database. Before a node can join a WAAS
network, it must first be registered and then activated. The cms enable global configuration command
automatically registers the node in the database management tables and enables the CMS. The node
sends its attribute information to the WAAS Central Manager over the SSL protocol and then stores the
new node information. The WAAS Central Manager accepts these node registration requests without
admission control and replies with registration confirmation and other pertinent security information
required for getting updates. Activate the node using the WAAS Central Manager GUI.
Once the node is activated, it automatically receives configuration updates and the necessary security
RSA certificate-key pair from the WAAS Central Manager. This security key allows the node to
communicate with any other node in the WAAS network. The cms deregister command removes the
node from the WAAS network by deleting registration information and database tables.
To back up the existing management database for the WAAS Central Manager, use the cms database
backup command. For database backups, specify the following items:
•
Location, password, and user ID
•
Dump format in PostgreSQL plain text syntax
The naming convention for backup files includes the time stamp.
Note
For information on the procedure to back up and restore the CMS database on the WAAS Central
Manager, see the Cisco Wide Area Application Services Configuration Guide.
When you use the cms recover identity word command when recovering lost registration information,
or replacing a failed node with a new node that has having the same registration information, you must
specify the device recovery key that you configured in the Modifying Config Property,
System.device.recovery.key window of the WAAS Central Manager GUI.
Use the lcm command to configure local/central management (LCM) on a WAE. The LCM feature
allows settings that are configured using the device CLI or GUI to be stored as part of the WAAS
network-wide configuration data (enable or disable).
When you enter the cms lcm enable command, the CMS process running on WAEs and the standby
WAAS Central Manager detects the configuration changes that you made on these devices using CLIs
and sends the changes to the primary WAAS Central Manager.
Cisco Wide Area Application Services Command Reference
OL-11817-01

Chapter 3 CLI Commands
cms
When you enter the cms lcm disable command, the CMS process running on the WAEs and the standby
WAAS Central Manager does not send the CLI changes to the primary WAAS Central Manager. Settings
configured using the device CLIs will not be sent to the primary WAAS Central Manager.
If LCM is disabled, the settings configured through the WAAS Central Manager GUI will overwrite the
settings configured from the WAEs; however, this rule applies only to those local device settings that
have been overwritten by the WAAS Central Manager when you have configured the local device
settings. If you (as the local CLI user) change the local device settings after the particular configuration
has been overwritten by the WAAS Central Manager, the local device configuration will be applicable
until the WAAS Central Manager requests a full device statistics update from the WAEs (clicking the
Force full database update button from the Device Home window of the WAAS Central Manager GUI
triggers a full update). When the WAAS Central Manager requests a full update from the device, the
WAAS Central Manager settings will overwrite the local device settings.
Examples
The following example backs up the cms database management tables on the WAAS Central Manager
named waas-cm:
waas-cm# cms database backup
creating backup file with label `backup'
backup file local1/acns-db-9-22-2002-17-36.dump is ready. use `copy' commands to move the
backup file to a remote host.
The following example validates the cms database management tables on the WAAS Central Manager
named waas-cm:
waas-cm# cms database validate

Upgrading the BIOS
You can remotely upgrade the BIOS on the WAE-511, WAE-512, WAE-611, WAE-612, and the
WAE-7326. All computer hardware has to work with software through an interface. The Basic Input
Output System (BIOS) provides such an interface. It gives the computer a built-in starter kit to run the
rest of the software from the hard disk drive. The BIOS is responsible for booting the computer by
providing a basic set of instructions. It performs all the tasks that need to be done at start-up time, such
as Power-On Self Test (POST) operations and booting the operating system from the hard disk drive.
Furthermore, it provides an interface between the hardware and the operating system in the form of a
library of interrupt handlers. For instance, each time a key is pressed, the CPU performs an interrupt to
read that key, which is similar for other input/output devices, such as serial and parallel ports, video
cards, sound cards, hard disk controllers, and so forth. Some older PCs cannot interoperate with all the
modern hardware because their BIOS does not support that hardware; the operating system cannot call
a BIOS routine to use it. This problem can be solved by replacing the BIOS with a newer one that does
support your new hardware or by installing a device driver for the hardware.
All BIOS files needed for a particular hardware model BIOS update are available on Cisco.com as a
single .bin package file. This file is a special <WAAS-installable>.bin file that you can install by using
the normal software update procedure.
To update the BIOS version on a WAAS device that supports BIOS version updates, you need the following
items:
•
FTP server with the software files
•
Network connectivity between the device to be updated and the server hosting the update files
•
Appropriate .bin BIOS update file:
– 511_bios.bin
– 611_bios.bin
– 7326_bios.bin

Caution
Be extraordinarily careful when upgrading a Flash BIOS. Make absolutely sure that the BIOS upgrade
patch is the exact one required. If you apply the wrong patch, you can render the system unbootable,
making it difficult or impossible to recover even by reapplying the proper patch.
Caution
Because a failed Flash BIOS update can have dire results, never update a Flash BIOS without first
connecting the system to an uninterruptible power supply (UPS).
To remotely install a BIOS update file, use the copy ftp install EXEC command as follows:
WAE# copy ftp install ftp-server remote_file_dir 7326_bios.bin
After the BIOS update file is copied to your system, use the reload EXEC command to reboot as follows:
WAE# reload
The new BIOS takes effect after the system reboots.

Usage Guidelines
Use the copy http install EXEC command to install an image file from an HTTP server and install it on
a WAAS device. It transfers the image from an HTTP server to the WAAS device using HTTP as the
transport protocol and installs the software on the device. Part of the image goes to disk and part goes to
flash memory. Use the copy http central EXEC command to download a software image into the
repository from an HTTP server.
You can also use the copy http install EXEC commands to redirect your transfer to a different location
or HTTP proxy server, by specifying the proxy hostname | ip-address option. A username and a
password have to be authenticated with a primary domain controller (PDC) before the transfer of the
software release file to the WAAS device is allowed.

Upgrading the BIOS
You can remotely upgrade the BIOS on the WAE-511, WAE-512, WAE-611, WAE-612, and the
WAE-7326. All computer hardware has to work with software through an interface. The Basic Input
Output System (BIOS) provides such an interface. It gives the computer a built-in starter kit to run the
rest of the software from the hard disk drive. The BIOS is responsible for booting the computer by
providing a basic set of instructions. It performs all the tasks that need to be done at start-up time, such
as Power-On Self Test (POST) operations and booting the operating system from the hard disk drive.
Furthermore, it provides an interface between the hardware and the operating system in the form of a
library of interrupt handlers. For instance, each time a key is pressed, the CPU performs an interrupt to
read that key, which is similar for other input/output devices, such as serial and parallel ports, video
cards, sound cards, hard disk controllers, and so forth. Some older PCs cannot interoperate with all the
modern hardware because their BIOS does not support that hardware; the operating system cannot call
a BIOS routine to use it. This problem can be solved by replacing the BIOS with a newer one that does
support your new hardware or by installing a device driver for the hardware.
All BIOS files needed for a particular hardware model BIOS update are available on Cisco.com as a
single .bin package file. This file is a special <WAAS-installable>.bin file that you can install by using
the normal software update procedure.
To update the BIOS version on a WAAS device that supports BIOS version updates, you need the following
items:
•
HTTP server with the software files
•
Network connectivity between the device to be updated and the server hosting the update files
•
Appropriate .bin BIOS update file:
– 511_bios.bin
– 611_bios.bin
– 7326_bios.bin
Caution
Be extraordinarily careful when upgrading a Flash BIOS. Make absolutely sure that the BIOS upgrade
patch is the exact one required. If you apply the wrong patch, you can render the system unbootable,
making it difficult or impossible to recover even by reapplying the proper patch.
Caution
Because a failed Flash BIOS update can have dire results, never update a Flash BIOS without first
connecting the system to an uninterruptible power supply (UPS).
To install the BIOS update file on a WAAS device, use the copy http install EXEC command as follows:
WAE# copy http install http-server remote_file_dir 7326_bios.bin
[portnumber]
After the BIOS update file is copied to your system, use the reload EXEC command to reboot the WAAS
device as follows:
WAE# reload
The new BIOS takes effect after the system reboots.

Usage Guidelines
A WAAS device can use two disk drives to increase storage capacity or to increase reliability. This is
known as Redundant Array of Independent Disks (RAID) and is implemented in WAAS as a software
feature.
RAID-1 is automatically applied to any WAAS device that is running the WAAS software and that have
two or more disk drives. RAID-1 provides disk mirroring (data is written redundantly to two or more
drives). The goal is higher reliability through redundancy. With RAID-1, file system write performance
may be affected because each disk write must be executed against two disk drives.
Cisco Wide Area Application Services Command Reference
OL-11817-01
3-43
Chapter 3 CLI Commands
disk
RAID-1 (mirroring) is used for all file systems on the device. This setup ensures reliable execution of
the software in all cases.
Note
The WAAS software uses the CONTENT file system for both the Wide Area File Services (WAFS) file
system and the data redundancy elimination (DRE) cache.
Manually Marking and Unmarking WAE Disk Drives
A disk drive on a WAAS device can be marked as a good drive, one that is operating properly and being
used, or as a bad drive, one that is not operating properly and will not be used after a reload command
is executed.
The following scenario shows how to mark disk01 as bad, reload the WAAS device, and then mark
disk01 as good so that it can be used again.
1.
Mark disk01 as bad by entering the disk mark EXEC command as follows:
WAE# disk mark disk01 bad
disk01 is marked as bad.
It will be not used after reload.
2.
Display the details about the disks by entering the show disks details EXEC command. Disk01 is
now shown with an asterisk (*) because it was marked after the WAAS device was booted. Notice
that Disk01 is reported as “Normal” (currently being used).
WAE# show disks details
Physical disk information:
disk00: Normal

Reformatting a SCSI Disk Drive
Use the disk reformat EXEC command to reformat a SCSI disk drive on a WAAS device. The SCSI
drive cannot be in use when you execute this command.
Caution
Note
To avoid loss of data, use this command with extreme caution.
This command is only available on systems with SCSI drives: WAE-611 and WAE-7326.
The following scenario shows how to reformat a SCSI drive:
1.
Mark the SCSI drive as bad. In this example, it is disk01.
WAE# disk mark disk01 bad
2.
Reboot the WAAS device so that the bad disk is not in use.
WAE# reload
3.
Reformat the disk. On completion of this command the drive is blank.
WAE# disk reformat disk01
4.
Reboot the WAAS device. Normal software RAID recovery is performed and the reformatted disk
is prepared for use.
WAE# reload

Removing All Disk Partitions on a Single Disk Drive
Use the disk delete-partitions EXEC command to remove all disk partitions on a single disk drive on
WAAS device.
Caution
After using the disk delete-partitions EXEC command, the WAAS software treats the specified disk
drive as blank. All previous data on the drive is inaccessible.
Use this command when you want to add a new disk drive that was previously used with another
operating system (for example, a Microsoft Windows or Linux operating system). When asked if you
want to erase everything on the disk, specify “yes” to proceed, as follows:
WAE# disk delete-partitions disk01
This will erase everything on disk. Are you sure? [no] yes

To install a new software image (such as the WAAS software) into flash on the WAAS device, use the
install EXEC command.
install imagefilename
Syntax Description
imagefilename
Defaults
No default behavior or values
Command Modes
EXEC
Device Modes
application-accelerator
Name of the .bin file you want to install.
central-manager
Usage Guidelines
Note
The install command loads the system image into flash memory and copies components of the optional
software to the software file system (swfs) partition.
If you are installing a system image that contains optional software, make sure that an SWFS partition
is mounted on disk00.
To install a system image, copy the image file to the SYSFS directory, local1 or local2. Before executing
the install command, change the present working directory to the directory where the system image
resides. When the install command is executed, the image file is expanded. The expanded files overwrite
the existing files on the WAAS device. The newly installed version takes effect after the system image
is reloaded.
Note
Examples
The install command does not accept .pax files. Files should be of the type .bin (for example,
cache-sw.bin). Also, if the release being installed does not require a new system image, then it may not
be necessary to write to Flash memory. If the newer version has changes that require a new system image
to be installed, then the install command may result in a write to Flash memory.
The following example loads the system image contained in the wae511-cache-300.bin file:
WAE# install wae511-cache-300.bin

LESS is an application that displays text files a page at a time. You can use LESS to view the contents
of a file, but not edit it. LESS offers some additional features when compared to conventional text file
viewer applications such as type. These features are as follows:
•
Backward movement—LESS allows you to move backward in the displayed text. Use k, Ctrl-k, y,
or Ctrl-y to move backward. See the summary of LESS commands for more details; to view the
summary, press h or H while displaying a file in LESS.
•
Searching and highlighting—LESS allows you to search for text in the file that you are viewing. You
can search forward and backward. LESS highlights the text that matches your search to make it easy
to see where the match is.
•
Multiple file support—LESS allows you to switch between different files, remembering your
position in each file. You can also do a search that spans all the files you are working with.
To display the text of the syslog.txt file using the LESS application, enter the following command:

restore
restore
To restore the device to its manufactured default status, removing user data from disk and flash memory,
use the restore EXEC command.
restore {factory-default [preserve basic-config] | rollback}
Syntax Description
factory-default
Resets the device configuration and data to their manufactured default
status.
preserve
(Optional) Preserves certain configurations and data on the device.
basic-config
(Optional) Selects basic network configurations.
rollback
Roll back configuration to the last functional software and device
configuration.
Defaults
No default behavior or values
Command Modes
EXEC
Device Modes
application-accelerator
central-manager
Usage Guidelines
Use this EXEC command to restore data on disk and in flash memory to the factory default, while
preserving particular time stamp evaluation data, or to roll back the configuration to the last functional
data and device configuration.
This command erases all existing content on the device; however, your network settings are preserved
and the device is accessible through a Telnet and Secure Shell (SSH) session after it reboots.
Backing up the Central Manager Database
Before you use the restore factory-default command on your primary WAAS Central Manager or
change over from the primary to a standby WAAS Central Manager, be sure to back up the WAAS
Central Manager database and copy the backup file to a safe location that is separate from that of the
WAAS Central Manager. You must halt the operation of the WAAS Central Manager before you enter
the backup and restore commands.
Caution
This command erases user-specified configuration information stored in the flash image, removes data
on disk, user-defined disk partitions, and the entire Central Manager database. User-defined disk
partitions that are removed include the SYSFS, WAAS, and PRINTSPOOLFS partitions. The
configuration being removed includes the starting configuration of the device.
Cisco Wide Area Application Services Command Reference

OL-11817-01
Chapter 3 CLI Commands
restore
By removing the WAAS Central Manager database, all configuration records for the entire WAAS
network are deleted. If you do not have a valid backup file or a standby WAAS Central Manager, you
must reregister every WAE with the WAAS Central Manager because all previously configured data is
lost.
If you used your standby WAAS Central Manager to store the database while you reconfigured the
primary, you can simply register the former primary as a new standby WAAS Central Manager.
If you created a backup file while you configured the primary WAAS Central Manager, you can copy the
backup file to this newly reconfigured WAAS Central Manager.
Rolling Back the Configuration
You can roll back the software and configuration of a WAAS device to a previous version using the
restore rollback command. You would roll back software only in cases in which a newly installed
version of the WAAS software is not functioning properly.
The restore rollback command installs the last saved WAAS.bin image on the system disk. A WAAS.bin
image is created during software installation and stored on the system disk. If the WAAS device does
not have a saved version, the software is not rolled back.
Note
Examples
While WAFS to WAAS migration is supported, rollback from WAAS to WAFS is not supported.
The following two examples show how to use the restore factory-default and restore factory-default
preserve basic-config commands. Because configuration parameters and data are lost, prompts are
given before initiating the restore operation to ensure that you want to proceed.
WAE# restore factory-default
This command will wipe out all of data on the disks
and wipe out WAAS CLI configurations you have ever made.
If the box is in evaluation period of certain product,
the evaluation process will not be affected though.
It is highly recommended that you stop all active services
before this command is run.
Are you sure you want to go ahead?[yes/no]
WAE# restore factory-default preserve basic-config
This command will wipe out all of data on the disks
and all of WAAS CLI configurations except basic network
configurations for keeping the device online.
The to-be-preserved configurations are network interfaces,
default gateway, domain name, name server and hostname.
If the box is in evaluation period of certain product,
the evaluation process will not be affected.
It is highly recommended that you stop all active services
before this command is run.
Are you sure you want to go ahead?[yes/no]
Note
You can enter basic configuration parameters (such as IP address, hostname, and name server) at this
point, or later through entries in the command-line interface.

The following example shows how to upgrade or restore an older version of the WAAS software. In the
first example below, version Y of the software is installed (using the copy command), but the
administrator has not switched over to it yet, so the current version is still version X. The system is then
reloaded (using the reload command), and it verifies that version Y is the current version running.
The final example shows that the software is rolled back to version X (using the restore rollback
command), and the software is reloaded again.

Usage Guidelines
The Node Health Manager in the WAAS software enables WAAS applications to raise alarms to draw
attention in error/significant conditions. The Node Health Manager, which is the data repository for such
alarms, aggregates the health and alarm information for the applications, services, and resources (for
example, disk drives) that are being monitored on the WAAS device. For example, this feature gives you
a mechanism to determine if a WAE is receiving overwhelming number of alarms. These alarms are
referred to as “WAAS software alarms.”
WAAS software uses SNMP to report error conditions by generating SNMP traps. The following WAAS
applications can generate a WAAS software alarm:
•
Node Health Manager (Alarm overload condition)
•
System Monitor (sysmon) for disk failures
Cisco Wide Area Application Services Command Reference

OL-11817-01
Chapter 3 CLI Commands
show alarms
The three levels of alarms in WAAS software are as follows:
•
Critical—Alarms that affect the existing traffic through the WAE, and are considered fatal (the WAE
cannot recover and continue to process traffic).
•
Major—Alarms which indicate a major service (for example, the cache service) has been damaged
or lost. Urgent action is necessary to restore this service. However, other node components are fully
functional and the existing service should be minimally impacted.
•
Minor—Alarms which indicate that a condition that will not affect a service has occurred, but that
corrective action is required to prevent a serious fault from occurring.
You can configure alarms using the snmp-server enable traps alarms global configuration command.
Use the show alarms critical EXEC command to display the current critical alarms being generated by
WAAS software applications. Use the show alarms critical detail EXEC command to display additional
details for each of the critical alarms being generated. Use the show alarms critical detail support
EXEC command to display an explanation about the condition that triggered the alarm and how you can
find out the cause of the problem. Similarly, you can use the show alarms major and show alarms
minor EXEC commands to display the details of major and minor alarms.
Use the show alarms history EXEC command to display a history of alarms that have been raised and
cleared by WAAS software on the WAAS device since the last software reload. The WAAS software
retains the last 100 alarm raise and clear events only.
Use the show alarms status EXEC command to display the status of current alarms, and the WAAS
device’s alarm overload status and alarm overload configuration.
Examples

Usage Guidelines
The WAAS device has several predefined “standard” time zones. Some of these time zones have built-in
summer time information while others do not. For example, if you are in an eastern region of the United
States (US), you must use US/Eastern time zone that includes summer time information for the system
clock to adjust automatically every April and October. There are about 1500 “standard” time zone
names.
Strict checking disables the clock summertime command when a standard time zone is configured. You
can only configure summertime if the time zone is not a standard time zone (that is, if the time zone is
a “customized zone”).
The show clock standard-timezones all EXEC command enables you to browse through all standard
timezones and choose from these predefined time zones. This enables you to choose a customized name
that does not conflict with the predefined names of the standard time zones. Most predefined names of
the standard time zones have two components, a region name and a zone name. You can list time zones
by several criteria, such as regions and zones. To display all first level time zone names organized into
directories by region, use the show clock standard-timezones region EXEC command.
The show clock command displays the local date and time information and the show clock detail
command shows optional detailed date and time information.

Usage Guidelines
You must deploy the WAAS Central Manager on a dedicated appliance. The device mode feature allows
you to deploy a WAAS device as either a WAAS Central Manager or a WAE. Because you must deploy
a WAAS Central Manager on a dedicated appliance, a WAAS device can only operate in one device
mode; either in central-manager mode or application-accelerator mode.
If the configured and current device modes differ, a reload is required for the configured device mode to
take effect.
To display the current device mode of a WAAS device, enter the show device mode EXEC command:
WAE# show device mode
To display the current mode in which the WAAS device is operating, enter the show device-mode
current EXEC command:
WAE# show device-mode current
Current device mode: application-accelerator
To display the configured device mode that has not yet taken effect, enter the show device-mode

configuration command on a WAAS device to change its device mode to central manager but have not
yet entered the copy run start EXEC command to save the running configuration on the device, then if
you were to enter the show device-mode configured command on the WAAS device, the command

Proactively Monitoring Disk Health with SMART
The ability to proactively monitor the health of disks is available using SMART. SMART provides you
with hard drive diagnostic information and information about impending disk failures.
SMART is supported by most disk vendors and is a standard method used to determine how healthy a
disk is. SMART attributes include several read-only attributes (for example, the power on hours attribute,
the load and unload count attribute) that provide the WAAS software with information regarding the
operating and environmental conditions that may indicate an impending disk failure.
SMART support is vendor and drive technology (IDE or SCSI disk drives) dependent. Each disk vendor
has a different set of supported SMART attributes.
Even though SMART attributes are vendor dependent there is a common way of interpreting most
SMART attributes. Each SMART attribute has a normalized current value and a threshold value. When
the current value exceeds the threshold value, the disk is considered to have “failed.” The WAAS
software monitors the SMART attributes and reports any impending failure through syslog messages,
SNMP traps, and alarms.
To display SMART information, use the show disks SMART-info EXEC command. To display more
detailed SMART information, enter the show disks SMART-info details EXEC command. The output
from the show tech-support EXEC command also includes SMART information.

Usage Guidelines
The show inventory EXEC command allows you to view the UDI for a WAAS device. This identity
information is stored in the WAAS device’s nonvolatile memory.
The UDI is electronically accessed by the product operating system or network management application
to enable identification of unique hardware devices. The data integrity of the UDI is vital to customers.
The UDI that is programmed into the WAAS device’s nonvolatile memory is equivalent to the UDI that
is printed on the product label and on the carton label. This UDI is also equivalent to the UDI that can
be viewed through any electronic means and in all customer-facing systems and tools. Currently, there
is only CLI access to the UDI; there is no SNMP access to the UDI information.
You can also use the show tech-support EXEC command to display the WAAS device UDI.

Number of number of failures detected by the IP reassembly
algorithm (for whatever reason: timed out, errors, and so forth).
This count is not necessarily a count of discarded IP fragments
because some algorithms (notably the algorithm in RFC 815)
can lose track of the number of fragments by combining them
as they are received.
Fragments received
Total number of IP datagrams that have been successfully
fragmented at this entity.

Usage Guidelines
GRE is a Layer 3 technique that allows datagrams to be encapsulated into IP packets at the
WCCP-enabled router and then redirected to a WAE (the transparent proxy server). At this intermediate
destination, the datagrams are decapsulated and then routed to an origin server to satisfy the request if a
cache miss occurs. In doing so, the trip to the origin server appears to the inner datagrams as one hop.
Usually, the redirected traffic using GRE is referred to as GRE tunnel traffic. With GRE, all redirection
is handled by the router software.
Displays WCCP generic routing encapsulation packet-related statistics.
With WCCP redirection, a Cisco router does not forward the TCP SYN packet to the destination because
the router has WCCP enabled on the destination port of the connection. Instead, the WCCP-enabled
router encapsulates the packet using GRE tunneling and sends it to the WAE that has been configured to
accept redirected packets from this WCCP-enabled router.
After receiving the redirected packet, the WAE does the following:
1.
Strips the GRE layer from the packet.
2.
Decides whether it should accept this redirected packet and process the request for the content as
follows:
a. If the WAE accepts the request, it sends a TCP SYN ACK packet to the client. In this response
packet, the WAE uses the IP address of the original destination (origin server) that was specified
as the source address so that the WAE can be invisible (transparent) to the client; it acts as if it
is the destination that the client’s TCP SYN packet was trying to reach.
b. If the WAE does not accept the request, it reencapsulates the TCP SYN packet in GRE and sends
it back to the WCCP-enabled router. The router identifies that the WAE is not interested in this
connection and forwards the packet to its original destination (the origin server).
For example, a WAE would not accept the request because it is configured to bypass requests that
originate from a certain set of clients or that are destined to a particular set of servers.

Description
Transparent GRE packets
received
Total number of GRE packets received by the WAE, regardless of
whether or not they have been intercepted by WCCP. GRE is a
Layer 3 technique that allows packets to reach the WAE, even if
there are any number of routers in the path to the WAE.
Transparent non-GRE packets
received
Number of non-GRE packets received by the WAE, either using
the traffic interception and redirection functions of WCCP in the
router hardware at Layer 2 or Layer 4 switching (a Content
Switching Module [CSM]) that redirects requests transparently to
the WAE.
Transparent non-GRE packets
passed through
Number of non-GRE packets transparently intercepted by a
Layer 4 switch and redirected to the WAE.
Total packets accepted
Total number of packets that are transparently intercepted and
redirected to the WAE to serve client requests for content.
Invalid packets received
Number of packets that are dropped either because the redirected
packet is a GRE packet and the WCCP GRE header has invalid
data or the IP header of the redirected packet is invalid.
Packets received with invalid
service
Number of WCCP version 2 GRE redirected packets that contain
an invalid WCCP service number.
Packets received on a disabled
service
Number of WCCP version 2 GRE redirected packets that specify
the WCCP service number for a service that is not enabled on the
WAE. For example, an HTTPS request redirected to the WAE
when the HTTPS-caching service (service 70) is not enabled.
Packets received too small
Number of GRE packets redirected to the WAE that do not
contain the minimum amount of data required for a WCCP GRE
header.
Packets dropped due to zero TTL
Number of GRE packets that are dropped by the WAE because the
redirected packet’s IP header has a zero TTL.
Packets dropped due to bad
buckets
Number of packets that are dropped by the WAE because the
WCCP flow redirection could not be performed due to a bad mask
or hash bucket determination.
Note
A bucket is defined as a certain subsection of the allotted
hash assigned to each WAE in a WAE cluster. If only one
WAE exists in this environment, it has 256 buckets
assigned to it.
Packets dropped due to no redirect Number of packets that are dropped because the flow redirection
address
destination IP address could not be determined.
Packets dropped due to loopback
redirect
Number of packets that are dropped by the WAE when the
destination IP address is the same as the loopback address.
Pass-through pkts dropped on
assignment update
Number of packets that were targeted for TFO pass-through, but
were dropped instead because the bucket was not owned by the
device.

Field
Description
Connections bypassed due to load Number of connection flows that are bypassed when the WAE is
overloaded. When the overload bypass option is enabled, the
WAE bypasses a bucket and reroutes the overload traffic. If the
load remains too high, another bucket is bypassed, and so on, until
the WAE can handle the load.
Packets sent back to router
Number of requests that are passed back by the WAE to the
WCCP-enabled router from which the request was received. The
router then sends the flow toward the origin web server directly
from the web browser, which bypasses the WAE.
Packets sent to another WAE
Number of packets that are redirected to another WAE in the
WCCP service group. Service groups consist of up to 32 WAEs
and 32 WCCP-enabled routers. In both packet-forwarding
methods, the hash parameters specify how redirected traffic
should be load balanced among the WAEs in the various WCCP
service groups.
GRE fragments redirected
Number of GRE packets received by the WAE that are
fragmented. These packets are redirected back to the router.
GRE encapsulated fragments
received
Number of GRE encapsulated fragments received by the WAE.
The tcp-promiscuous service does not inspect port information
and therefore the router or switch may GRE encapsulate IP
fragments and redirect them to the WAE. These fragments are
then reassembled into packets before being processed.
Packets failed encapsulated
reassembly
Number of reassembled GRE encapsulated packets that were
dropped because they failed the reassembly sanity check.
Reassembled GRE encapsulated packets are composed of two or
more GRE encapsulated fragments. This field is related to the
previous statistic.
Packets failed GRE encapsulation Number of GRE packets that are dropped by the WAE because
they could not be redirected due to problems while encapsulating
the packet with a GRE header.
Packets dropped due to invalid
fwd method
Number of GRE packets that are dropped by the WAE because it
was redirected using GRE but the WCCP service was configured
for Layer 2 redirection.
Packets dropped due to
insufficient memory
Number of GRE packets that are dropped by the WAE due to the
failure to allocate additional memory resources required to handle
the GRE packet.
Packets bypassed, no conn at all
Number of packets that failed to be associated with an existing
flow because no TCP port was listening. WCCP can also handle
asymmetric packet flows and always maintains a consistent
mapping of web servers to caches regardless of the number of
switches or routers used in a WCCP service group (up to 32
routers or switches communicating with up to 32 WAEs in a
cluster).
Packets bypassed, no pending
connection
Number of packets that failed to be associated with a pending
connection because the initial handshake was not completed.

Field
Description
Packets due to clean wccp
shutdown
Number of connection flows that are bypassed due to a clean
WCCP shutdown. During a proper shutdown of WCCP, the WAE
continues to service the flows it is handling but starts to bypass
new flows. When the number of flows goes down to zero, the
WAE takes itself out of the cluster by having its buckets
reassigned to other WAEs by the lead WAE.
Packets bypassed due to
bypass-list lookup
Number of connection flows that are bypassed due to a bypass list
entry. When the WAE receives an error response from an origin
server, it adds an entry for the server to its bypass list. When it
receives subsequent requests for the content residing on the
bypassed server, it redirects packets to the bypass gateway. If no
bypass gateway is configured, then the packets are returned to the
redirecting Layer 4 switch.
Packets received with client IP
addresses
Number of packets that are associated to a connection flow that is
being spoofed. By spoofing a client’s IP address, the WAE can
receive packets with the client IP (which is different from the
WAE’s own IP address) and send the packet to the correct
application that is waiting for the packet.
Conditionally Accepted
connections
Number of connection flows that are accepted by the WAE due to
the conditional accept feature.
Conditionally Bypassed
connections
Number of connection flows that are bypassed by the WAE due to
the conditional accept feature.
Packets dropped due to received
on loopback
Number of packets that were dropped by the WCCP L2 intercept
layer because they were received on the loopback interface but
were not destined to a local address of the device. There is no
valid or usable route for the packet.
Packets w/WCCP GRE received
too small
Number of packets transparently intercepted by the
WCCP-enabled router at Layer 2 and sent to the WAE that need
to be fragmented for the packets to be redirected using GRE. The
WAE drops the packets since it cannot encapsulate the IP header.
Packets dropped due to IP
access-list deny
Number of packets that are dropped by the WAE when an IP
access list that the WAE applies to WCCP GRE encapsulated
packets denies access to WCCP applications (the wccp
access-list command).
Packets fragmented for bypass
Number of GRE packets that do not contain enough data to hold
an IP header.
Packet pullups needed
Number of times a packet had to be consolidated as part of its
processing. Consolidation is required when a packet is received as
fragments and the first fragment does not contain all the
information needed to process it.
Packets dropped due to no route
found
Number of packets that are dropped by the WAE because it cannot
find the route.

show wccp
Examples
Table 3-88 describes the fields shown in the show wccp gre display.
Table 3-88
Field Descriptions for the show wccp gre Command
Field
Description
Transparent GRE packets
received
Total number of GRE packets received by the WAE, regardless of
whether or not they have been intercepted by WCCP. GRE is a
Layer 3 technique that allows packets to reach the WAE, even if
there are any number of routers in the path to the WAE.
Transparent non-GRE packets
received
Number of non-GRE packets received by the WAE, either using
the traffic interception and redirection functions of WCCP in the
router hardware at Layer 2 or Layer 4 switching (a Content
Switching Module [CSM] ) that redirects requests transparently
to the WAE.
Transparent non-GRE packets
passed through
Number of non-GRE packets transparently intercepted by a
Layer 4 switch and redirected to the WAE.
Total packets accepted
Total number of packets that are transparently intercepted and
redirected to the WAE to serve client requests for content.
Invalid packets received
Number of packets that are dropped either because the redirected
packet is a GRE packet and the WCCP GRE header has invalid
data or the IP header of the redirected packet is invalid.
Packets received with invalid
service
Number of WCCP version 2 GRE redirected packets that contain
an invalid WCCP service number.
Packets received on a disabled
service
Number of WCCP version 2 GRE redirected packets that specify
the WCCP service number for a service that is not enabled on the
WAE. For example, an HTTPS request redirected to the WAE
when the HTTPS-caching service (service 70) is not enabled.
Packets received too small
Number of GRE packets redirected to the WAE that do not
contain the minimum amount of data required for a WCCP GRE
header.
Packets dropped due to zero TTL
Number of GRE packets that are dropped by the WAE because the
redirected packet’s IP header has a zero TTL.
Packets dropped due to bad
buckets
Number of packets that are dropped by the WAE because the
WCCP flow redirection could not be performed due to a bad mask
or hash bucket determination.
Note
A bucket is defined as a certain subsection of the allotted
hash assigned to each WAE in a WAE cluster. If only one
WAE exists in this environment, it has 256 buckets
assigned to it.
Packets dropped due to no redirect Number of packets that are dropped because the flow redirection
address
destination IP address could not be determined.
Packets dropped due to loopback
redirect
Number of packets that are dropped by the WAE when the
destination IP address is the same as the loopback address.
Pass-through pkts dropped on
assignment update
Number of packets that were targeted for TFO pass-through, but
were dropped instead because the bucket was not owned by the
device.

Chapter 3 CLI Commands
show wccp
Table 3-88
Field Descriptions for the show wccp gre Command (continued)
Field
Description
Connections bypassed due to load Number of connection flows that are bypassed when the WAE is
overloaded. When the overload bypass option is enabled, the
WAE bypasses a bucket and reroutes the overload traffic. If the
load remains too high, another bucket is bypassed, and so on, until
the WAE can handle the load.
Packets sent back to router
Number of requests that are passed back by the WAE to the
WCCP-enabled router from which the request was received. The
router then sends the flow toward the origin web server directly
from the web browser, which bypasses the WAE.
Packets sent to another WAE
Number of packets that are redirected to another WAE in the
WCCP service group. Service groups consist of up to 32 WAEs
and 32 WCCP-enabled routers. In both packet-forwarding
methods, the hash parameters specify how redirected traffic
should be load balanced among the WAEs in the various WCCP
service groups.
GRE fragments redirected
Number of GRE packets received by the WAE that are
fragmented. These packets are redirected back to the router.
GRE encapsulated fragments
received
Number of GRE encapsulated fragments received by the WAE.
The tcp-promiscuous service does not inspect port information
and therefore the router or switch may GRE encapsulate IP
fragments and redirect them to the WAE. These fragments are
then reassembled into packets before being processed.
Packets failed encapsulated
reassembly
Number of reassembled GRE encapsulated packets that were
dropped because they failed the reassembly sanity check.
Reassembled GRE encapsulated packets are composed of two or
more GRE encapsulated fragments. This field is related to the
previous statistic.
Packets failed GRE encapsulation Number of GRE packets that are dropped by the WAE because
they could not be redirected due to problems while encapsulating
the packet with a GRE header.
Packets dropped due to invalid
fwd method
Number of GRE packets that are dropped by the WAE because it
was redirected using GRE but the WCCP service was configured
for Layer 2 redirection.
Packets dropped due to
insufficient memory
Number of GRE packets that are dropped by the WAE due to the
failure to allocate additional memory resources required to handle
the GRE packet.
Packets bypassed, no conn at all
Number of packets that failed to be associated with an existing
flow because no TCP port was listening. WCCP can also handle
asymmetric packet flows and always maintains a consistent
mapping of web servers to caches regardless of the number of
switches or routers used in a WCCP service group (up to 32
routers or switches communicating with up to 32 WAEs in a
cluster).
Packets bypassed, no pending
connection
Number of packets that failed to be associated with a pending
connection because the initial handshake was not completed.

show wccp
Table 3-88
Field Descriptions for the show wccp gre Command (continued)
Field
Description
Packets due to clean wccp
shutdown
Number of connection flows that are bypassed due to a clean
WCCP shutdown. During a proper shutdown of WCCP, the WAE
continues to service the flows it is handling but starts to bypass
new flows. When the number of flows goes down to zero, the
WAE takes itself out of the cluster by having its buckets
reassigned to other WAEs by the lead WAE.
Packets bypassed due to
bypass-list lookup
Number of connection flows that are bypassed due to a bypass list
entry. When the WAE receives an error response from an origin
server, it adds an entry for the server to its bypass list. When it
receives subsequent requests for the content residing on the
bypassed server, it redirects packets to the bypass gateway. If no
bypass gateway is configured, then the packets are returned to the
redirecting Layer 4 switch.
Packets received with client IP
addresses
Number of packets that are associated to a connection flow that is
being spoofed. By spoofing a client’s IP address, the WAE can
receive packets with the client IP (which is different from the
WAE’s own IP address) and send the packet to the correct
application that is waiting for the packet.
Conditionally Accepted
connections
Number of connection flows that are accepted by the WAE due to
the conditional accept feature.
Conditionally Bypassed
connections
Number of connection flows that are bypassed by the WAE due to
the conditional accept feature.
Packets dropped due to received
on loopback
Number of packets that were dropped by the WCCP L2 intercept
layer because they were received on the loopback interface but
were not destined to a local address of the device. There is no
valid or usable route for the packet.
Packets w/WCCP GRE received
too small
Number of packets transparently intercepted by the
WCCP-enabled router at Layer 2 and sent to the WAE that need
to be fragmented for the packets to be redirected using GRE. The
WAE drops the packets since it cannot encapsulate the IP header.
Packets dropped due to IP
access-list deny
Number of packets that are dropped by the WAE when an IP
access list that the WAE applies to WCCP GRE encapsulated
packets denies access to WCCP applications (the wccp
access-list command).
Packets fragmented for bypass
Number of GRE packets that do not contain enough data to hold
an IP header.
Packet pullups needed
Number of times a packet had to be consolidated as part of its
processing. Consolidation is required when a packet is received as
fragments and the first fragment does not contain all the
information needed to process it.
Packets dropped due to no route
found
Number of packets that are dropped by the WAE because it cannot
find the route.

Usage Guidelines
A controlled shutdown refers to the process of properly shutting down a WAAS device without turning
off the power on the device. With a controlled shutdown, all of the application activities and the
operating system are properly stopped on a WAE, but the power remains on. Controlled shutdowns of a
WAAS device can help you minimize the downtime when the WAAS device is being serviced.
Caution
If a controlled shutdown is not performed, the WAAS file system can be corrupted. Rebooting the WAAS
device takes longer if it was not properly shut down.
Note
A WAAS device cannot be powered on again through the WAAS software after a software poweroff. You
must press the power button once on a WAAS device to bring it back online.
The shutdown EXEC command facilitates a proper shutdown for WAAS device, and is supported on all
WAE hardware models. The shutdown poweroff command is also supported by all of the WAE
hardware models as they support the ACPI.
The shutdown command closes all applications and stops all system activities, but keeps the power on.
The fans continue to run and the power LED is on, indicating that the device is still powered on. The
device console displays the following menu after the shutdown process is completed:
================= SHUTDOWN SHELL =================

Usage Guidelines
Using the snmp trigger global configuration command, you can define additional SNMP traps for other
MIB objects of interest to your particular configuration. You can select any MIB object from any of the
support MIBs for your trap. The trap can be triggered based on a variety of tests:
•
absent—A specified MIB object that was present at the last sampling is no longer present as of the
current sampling.
•
equal—The value of the specified MIB object is equal to the specified threshold.
•
falling—The value of the specified MIB object has fallen below the specified threshold value. After
a trap is generated against this condition, another trap for this same condition is not generated until
the sampled MIB object value rises above the threshold value and then falls below the falling
threshold value again.
•
greater-than—The value of the specified MIB object is greater than the specified threshold value.
•
less-than—The value of the specified MIB object is less than the specified threshold value.
•
on-change—The value of the specified MIB object has changed since the last sampling.
•
present—A specified MIB object is present as of the current sampling that was not present at the
previous sampling.
•
rising—The value of the specified MIB object has risen above the specified threshold. After a trap
is generated against this condition, another trap for this same condition is not generated until the
sampled MIB object value falls below the threshold value and then rises above the rising threshold
value again.
The threshold value can be based on an absolute sample type or on a delta sample type. An absolute
sample type is one in which the test is evaluated against a fixed integer value between zero and
4294967295. A delta sample type is one in which the test is evaluated against the change in the MIB
object value between the current sampling and the previous sampling.
After you configure SNMP traps, you must use the snmp-server enable traps event global
configuration command for the event traps you just created to be generated. Also, to preserve SNMP trap
configuration across a system reboot, you must configure event persistence using the snmp mib persist
event global configuration command, and save the MIB data using the write mib-data EXEC command.

SSH consists of a server and a client program. Like Telnet, you can use the client program to remotely
log in to a machine that is running the SSH server, but unlike Telnet, messages transported between the
client and the server are encrypted. The functionality of SSH includes user authentication, message
encryption, and message authentication.
The Telnet daemon can still be used with the WAAS device. SSH does not replace Telnet.

(Optional) Dump options.
central-manager
Usage Guidelines
TCPdump is a utility that allows a user to intercept and capture packets passing through a network
interface, making it useful for troubleshooting network applications.
During normal network operation, only the packets which are addressed to a network interface are
intercepted and passed on to the upper layers of the TCP/IP protocol layer stack. Packets which are not
addressed to the interface are ignored. In Promiscuous mode, the packets which are not intended to be
received by the interface are also intercepted and passed on to the higher levels of the protocol stack.
TCPdump works by putting the network interface into promiscuous mode. TCPdump uses the free
libpcap (packet capture library).
Use the -h option to view the options available, as shown in this example:
WAE# tcpdump -h
tcpdump version 3.8.1 (jlemon)
libpcap version 0.8
Usage: tcpdump [-aAdDeflLnNOpqRStuUvxX] [-c count] [ -C file_size ]
[ -E algo:secret ] [ -F file ] [ -i interface ] [ -r file ]
[ -s snaplen ] [ -T type ] [ -w file ] [ -y datalinktype ]
[ expression ]

traceroute
traceroute
To trace the route between a WAAS device to a remote host, use the traceroute EXEC command.
traceroute {hostname | ip-address}
Syntax Description
hostname
Name of remote host.
ip-address
IP address of remote host.
Defaults
No default behavior values
Command Modes
EXEC
Device Modes
application-accelerator

Usage Guidelines
Traceroute is a widely available utility on most operating systems. Much like ping, it is a valuable tool
for determining connectivity in a network. Ping allows the user to find out if there is a connection
between two end systems. Traceroute does this as well, but also lists the intermediate routers between
the two systems. Users can therefore see the possible routes packets can take from one system to another.
Use traceroute to find the route to a remote host, when either the hostname or the IP address is known.
Examples
The following example traces the route between the WAAS device and a device with an IP address of
10.0.0.0:
WAE# traceroute 10.0.0.0

(config) aaa accounting
Usage Guidelines
The AAA accounting feature enables you to track the activities of an administrative user, services that
users access, and the amount of network resources they consume (for example, connection time or the
bytes transferred). You can use the AAA accounting feature to track user activity for billing, auditing,
reporting, or security purposes. WAAS uses TACACS+ to implement AAA accounting; RADIUS is not
currently supported. When AAA accounting is enabled, the WAAS device reports user activity to the
TACACS+ security server in the form of accounting records. This data can then be analyzed for network
management, client billing, and auditing.
You can activate accounting for the following types of events:
•
EXEC—EXEC shell accounting is used to report the events of an administrator logging in and out
of the EXEC shell through Telnet, FTP, or SSH (SSH Version 1 or Version 2). This type of
accounting records information about user EXEC terminal sessions (user shells) on the WAAS
device, including username, date, start and stop times for each session, time zone, and IP address of
the system used to access the WAAS device. The EXEC shell accounting information can be
accessed through the accounting log file on the TACACS+ server. This log file uses the following
report format for this type of accounting information:
WeekDay#Month#Day#Time#Year#CEaddress#username#terminal#RemoteHost#Event#
EventTime#TaskId#Timezone#Service
•
Command—The WAAS device records information about the CLI commands that were executed on
the WAAS device. Each command accounting record includes the executed command syntax,
username of the user who executed the command, the privilege level of the user, and the date and
time that each command was executed. The WAAS device supports two privilege levels, 0 and 15,
representing normal users and administrative users, respectively. The command accounting
information can be accessed through the accounting log file on the TACACS+ server. This log file
uses the following report format for this type of accounting information:
WeekDay#Month#Day#Time#Year#CEaddress#username#terminal#RemoteHost#Event#
EventTime#TaskId#Timezone#Service#PrivilegeLevel#CLICommand
•
System—The WAAS device records information about all system-level events (for example, when
the system reboots). You can access the system accounting information through the accounting log
file on the TACACS+ server. This log file uses the following report format for this type of accounting
information:
WeekDay#Month#Day#Time#Year#CEaddress#username#terminal#RemoteHost#Event#
EventTime#TaskId#Timezone#SystemService#SystemAccountingEvent#EventReason
WAAS software supports only the default accounting list.
Caution
Before using the wait-start option, make sure that the WAAS device is configured with the TACACS+
server and is able to successfully contact the server. If the WAAS device cannot contact a configured
TACACS+ server, it might become unresponsive.
The WAAS software displays the following warning message if the wait-start option is configured:
Warning: The device may become non-responsive if it cannot contact a configured TACACS+
server.
The administrator is asked to confirm the configuration in an indefinite loop until the administrator
enters “yes” to the following prompt:
Are you sure you want to proceed? [yes]

(config) alarm overload-detect
When the WAAS device is in the alarm overload state, the following events occur:
•
An alarm overload notification is sent to SNMP and the NMS. The clear and raise values are also
communicated to SNMP and the NMS.
•
SNMP traps and NMS notifications for subsequent alarm raise and clear operations are suspended.
•
Alarm overload clear notification is sent.
•
The WAAS device remains in the alarm overload state until the rate of incoming alarms decreases
to the clear value.
Note
Examples
In the alarm overload state, applications continue to raise alarms and the alarms are recorded
within the WAAS device. The show alarms and show alarms history EXEC commands
display all the alarms even in the alarm overload state.
The following example enables detection of alarm overload:

Usage Guidelines
Note
The authentication command configures both the authentication and authorization methods that govern
login and configuration access to the WAAS device.
We strongly recommend that you use the WAAS Central Manager GUI instead of the WAAS CLI to
configure administrative login authentication and authorization for your WAAS devices, if possible. For
information about how to use the WAAS Central Manager GUI to centrally configure administrative
login authentication and authorization on an single WAE or group of WAEs, which are registered with a
WAAS Central Manager, see the Cisco Wide Area Application Services Configuration Guide.
The authentication login command determines whether the user has any level of permission to access
the WAAS device. The authentication configuration command authorizes the user with privileged
access (configuration access) to the WAAS device.
The authentication login local and the authentication configuration local commands use a local
database for authentication and authorization.
The authentication login tacacs and authentication configuration tacacs commands use a remote
TACACS+ server to determine the level of user access. WAAS software supports only TACACS+ and
not TACACS or Extended TACACS.
Cisco Wide Area Application Services Command Reference
OL-11817-01
3-261
Chapter 3 CLI Commands
(config) authentication
To configure TACACS+, use the authentication and tacacs commands. To enable TACACS+, use the
tacacs enable command. For more information on TACACS+ authentication, see the “(config)
tacacs”command.
The authentication login radius and authentication configuration radius commands use a remote
RADIUS server to determine the level of user access.
By default, the local method is enabled, with TACACS+ and RADIUS both disabled for login and
configuration. Whenever TACACS+ and RADIUS are disabled, local is automatically enabled.
TACACS+, RADIUS, and local methods can be enabled at the same time.
The primary option specifies the first method to attempt for both login and configuration; the secondary
option specifies the method to use if the primary method fails. The tertiary option specifies the method
to use if both primary and secondary methods fail. The quaternary option specifies the method to use
if the primary, secondary, and tertiary methods fail. If all methods of an authentication login or
authentication configuration command are configured as primary, or all as secondary or tertiary, local
is attempted first, then TACACS+, and then RADIUS.
Enforcing Authentication with the Primary Method
The authentication fail-over server-unreachable global configuration command allows you to specify
that failover to the secondary authentication method should occur only if the primary authentication
server is unreachable. This feature ensures that users gain access to the WAAS device using the local
database only when remote authentication servers (TACACS+ or RADIUS) are unreachable. For
example, when a TACACS+ server is enabled for authentication with user authentication failover
configured and the user tries to log in to the WAAS device using an account defined in the local database,
login fails. Login succeeds only when the TACACS+ server is unreachable.
Login Authentication and Authorization Through the Local Database
Local authentication and authorization uses locally configured login and passwords to authenticate
administrative login attempts. The login and passwords are local to each WAAS device and are not
mapped to individual usernames.
By default, local login authentication is enabled first. You can disable local login authentication only
after enabling one or more of the other administrative login authentication methods. However, when
local login authentication is disabled, if you disable all other administrative login authentication
methods, local login authentication is reenabled automatically.
Specifying RADIUS Authentication and Authorization Settings
To configure RADIUS authentication on a WAAS device, you must first configure a set of RADIUS
authentication server settings on the WAAS device by using the radius-server global configuration
command. (See the “(config) radius-server” command.)
Use the authentication login radius global configuration command to enable RADIUS authentication
for normal login mode.
Use the authentication configuration radius global configuration command to enable RADIUS
authorization.
To disable RADIUS authentication and authorization on a WAAS device, use the no form of the
authentication global configuration command (for example, use the no authentication login radius
enable command to disable RADIUS authentication).
Specifying TACACS+ Authentication and Authorization Settings
To configure TACACS+ authentication on WAAS devices, you must configure a set of TACACS+
authentication settings on the WAAS device by using the tacacs global configuration command. (See the
“(config) tacacs” command.)
Cisco Wide Area Application Services Command Reference
3-262
OL-11817-01
Chapter 3 CLI Commands
(config) authentication
Server Redundancy
Authentication servers can be specified with the tacacs host or radius-server host global configuration
commands. In the case of TACACS+ servers, the tacacs host hostname command can be used to
configure additional servers. These additional servers provide authentication redundancy and improved
throughput, especially when WAAS device load-balancing schemes distribute the requests evenly
between the servers. If the WAAS device cannot connect to any of the authentication servers, no
authentication takes place and users who have not been previously authenticated are denied access.
Specifying Windows Domain Login Authentication
You can enable Windows domain as an administrative login authentication and authorization method for
a device or device group. Before you enable Windows authentication, you must first configure the
Windows domain controller by using the using the windows-domain wins-server global configuration
command. (See the “(config) windows-domain” command.)
We recommend that you use the WAAS Central Manager GUI instead of the WAAS CLI to configure
Windows domain controller settings. See Chapter 6 of the Cisco Wide Area Application Services
Configuration Guide.
Examples
To query the secondary authentication database if the primary authentication server is unreachable, enter
the following command. This feature is referred to as the fail-over server-unreachable feature.
WAE(config)# authentication fail-over server-unreachable
If you enable the fail-over server-unreachable feature on the WAAS device, only two login
authentication scheme (a primary and secondary scheme) can be configured on the WAAS device. The
WAAS device fails over from the primary authentication scheme to the secondary authentication scheme
only if the specified authentication server is unreachable.
To enable authentication privileges using the local, TACACS+, RADIUS, or Windows databases, and to
specify the order of the administrative login authentication use the authentication login global
configuration command. In the following example, RADIUS is specified as the primary method,
TACACS+ as the secondary method, Windows as the third method, and the local database as the fourth
method. In this example, four login authentication methods are specified because the fail-over
server-unreachable feature is not enabled on the WAAS device.

If you have enabled the failover server unreachable feature on the WAAS device, make sure that
you specify either TACACS+ or RADIUS as the primary scheme for authentication, and specify
local as the secondary scheme for authentication.
To enable authorization privileges using the local, TACACS+, RADIUS, or Windows databases, and to
specify the order of the administrative login authorization (configuration), use the authentication
configuration global configuration command.

Note
Authorization privileges apply to console and Telnet connection attempts, secure FTP (SFTP)
sessions, and Secure Shell (SSH, Version 1 and Version 2) sessions.
We strongly recommend that you set the administrative login authentication and authorization
methods in the same order. For example, configure the WAAS device to use RADIUS as the
primary login method, TACACS+ as the secondary login method, Windows as the tertiary
method, and the local method as the quaternary method for both administrative login
authentication and authorization.
In the following example, RADIUS is specified as the primary method, TACACS+ as the secondary
method, Windows as the third method, and the local database as the fourth method. In this example, four
login authorization (configuration) methods are specified because the fail-over server-unreachable
feature is not enabled on the WAAS device.

(config) auto-register
(config) auto-register
To enable discovery of a Fast Ethernet or Gigabit Ethernet WAE and its automatic registration with the
WAAS Central Manager through Dynamic Host Configuration Protocol (DHCP), use the auto-register
global configuration command. To disable the autoregistration feature on a WAE, use the no form of this
command.
auto-register enable [FastEthernet slot/port | GigabitEthernet slot/port]
Syntax Description
enable
Enables the automatic registration of devices using DHCP with the WAAS
Central Manager.
FastEthernet
(Optional) Selects a Fast Ethernet interface for automatic registration using
DHCP.
slot/port
Fast Ethernet slot (0–3) and port number.
GigabitEthernet
(Optional) Selects a Gigabit Ethernet interface for automatic registration
using DHCP.
slot/port
Gigabit Ethernet slot (1–2) and port number.
Defaults
Automatic registration using DHCP is enabled on a WAE by default.
Command Modes
global configuration
Device Modes
application-accelerator
Usage Guidelines
Autoregistration automatically configures network settings and registers WAEs with the WAAS Central
Manager. On bootup, devices running WAAS software (with the exception of the WAAS Central
Manager itself) automatically discover the WAAS Central Manager and register with it. The
administrator does not have to do any manual configuration on the device. Once the WAE is registered,
the administrator approves the device and configures it remotely using the WAAS Central Manager GUI.
The auto-register enable command allows a Fast Ethernet or Gigabit Ethernet WAE to discover the
hostname of the WAAS Central Manager through DHCP and to automatically register the device with
the WAAS Central Manager. Discovery and registration occur at bootup.
To assign a static IP address using the interface GigabitEthernet slot/port command, the automatic
registration of devices through DHCP must be disabled by using the no auto-register enable command,
because automatic registration through DHCP is enabled by default.
Cisco Wide Area Application Services Command Reference
OL-11817-01
3-265
Chapter 3 CLI Commands
(config) auto-register
For autoregistration to work, you must have a DHCP server that is configured with the hostname of the
WAAS Central Manager and that is capable of handling vendor class option 43.
Note
The form of DHCP used for autoregistration is not the same as the interface-level DHCP that is
configurable through the ip address dhcp interface configuration command.
The DHCP server needs to send the vendor class option (option 43) information to the WAAS device in
the format for encapsulated vendor-specific options as provided in RFC 2132. The relevant section of
RFC 2132, Section 8.4, is reproduced here as follows:
You should encode the encapsulated vendor-specific options field as a sequence of code/length/value
fields of syntax identical to that of the DHCP options field with the following exceptions:
1.
There should not be a “magic cookie” field in the encapsulated vendor-specific extensions field.
2.
Codes other than 0 or 255 may be redefined by the vendor within the encapsulated vendor-specific
extensions field but should conform to the tag-length-value syntax defined in section 2.
3.
Code 255 (END), if present, signifies the end of the encapsulated vendor extensions, not the end of
the vendor extensions field. If no code 255 is present, then the end of the enclosing vendor-specific
information field is taken as the end of the encapsulated vendor-specific extensions field.
In accordance with the RFC standard, the DHCP server needs to send the WAAS Central Manager
hostname information in code/length/value format. (Code and length are single octets.) The code for the
WAAS Central Manager hostname is 0x01. DHCP server management and configuration are not within
the scope of the autoregistration feature.
The WAAS device sends CISCOCDN as the vendor class identifier in option 60 to facilitate device
groupings by customers.
Autoregistration DHCP also requires that the following options be present in the DHCP server’s offer to
be considered valid:
•
Subnet-mask (option 1)
•
Routers (option 3)
•
Domain-name (option 15)
•
Domain-name-servers (option 6)
•
Host-name (option 12)
Interface-level DHCP requires only subnet-mask (option 1) and routers (option 3) for an offer to be
considered valid; domain-name (option 15), domain-name-servers (option 6), and host-name (option 12)
are optional. All of the above options, with the exception of domain-name-servers (option 6), replace the
existing configuration on the system. The domain-name-servers option is added to the existing list of
name servers with the restriction of a maximum of eight name servers.
Autoregistration is enabled by default on the first interface of the device. The first interface depends on
the WAE model as follows:
•
For the WAE-511, WAE-512, WAE-611, WAE-612, and WAE-7320, use GigabitEthernet 1/0.
If you do not have a DHCP server, the device is unable to complete autoregistration and eventually times
out. You can disable autoregistration at any time after the device has booted and proceed with manual
setup and registration.

Usage Guidelines
You can configure the following three types of banners in any device mode:
Note
•
The MOTD banner sets the message of the day. This message is the first message that is displayed
when a login is attempted.
•
The login banner is displayed after the MOTD banner but before the actual login prompt appears.
•
The EXEC banner is displayed after the EXEC CLI shell has started.
All of these banners are effective on a console, Telnet, or a Secure Shell (SSH) version 2 session.
The message keyword is optional. If you enter a carriage return without specifying the message
keyword, you will be prompted to enter your message text. For message text on one or more lines, press
the Return key or enter delimiting characters (\n) to specify a message to appear on a new line. You can
enter up to a maximum of 980 characters, including new-line characters (\n). Enter a period (.) at the
beginning of a new line to save the message and return to the prompt for the global configuration mode.
Note
The EXEC banner content is obtained from the command-line input that the user enters after being
prompted for the input.

The following example shows how to use the banner motd message global configuration command to
configure the MOTD banner. In this example, the MOTD message consists of a single line of text.
WAE(config)# banner motd message This is a WAAS 4.0.7 device
The following example shows how to use the banner motd message global command to configure a
MOTD message that is longer than a single line. In this case, the WAE translates the \n portion of the
message to a new line when the MOTD message is displayed to the user.
WAE(config)# banner motd message "This is the motd message.
\nThis is a WAAS 4.0.7 device\n"
The following example shows how to use the banner login message global configuration command to
configure a login message that is longer than a single line. In this case, WAE A translates the \n portion
of the message to a new line in the login message that is displayed to the user.
WAE(config)# banner login message "This is login banner.
\nUse your password to login\n"
The following example shows how to enable banner support:
WAE(config)# banner enable
The following example shows how to use the banner exec global configuration command to configure
an interactive banner. The banner exec command is similar to the banner motd message commands
except that for the banner exec command, the banner content is obtained from the command-line input
that the user enters after being prompted for the input.
WAE(config)# banner exec
Please type your MOTD messages below and end it with '.' at beginning of line:
(plain text only, no longer than 980 bytes including newline)
This is the EXEC banner.\nUse your WAAS username and password to log in to this WAE.\n
.
Message has 99 characters.
WAE(config)#
Assume that a WAE has been configured with the MOTD, login, and EXEC banners as shown in the
previous examples. When a user uses an SSH session to log in to the WAE, the user will see a login
session that includes a MOTD banner and a login banner that asks the user to enter a login password as
follows:
This is the motd banner.
This is a WAAS 4.0.7 device
This is login banner.
Use your password to login.

Defaults
No default behaviors or values
Command Modes
global configuration
Device Modes

Usage Guidelines
Using a static bypass allows traffic flows between a configurable set of clients and file servers to bypass
handling by the WAE. By configuring static bypass entries on the Edge WAE, you can control traffic
interception without modifying the router configuration. Separately, if so desired, IP access lists may be
configured on the router to bypass traffic without first redirecting it to the Edge WAE. Typically, the
WCCP accept list defines the group of file servers that are cached (and the file servers that are not). Static
bypass can be used in rare cases when you want to prevent WAAS from caching a connection from a
certain client to a certain file server (or from a certain client to all file servers).
The bypass static command permits traffic from specified sources to bypass the WAE. Wildcards in
either the client or server IP addresses are not supported.
Note
Examples
We recommend that you use IP access lists on the WCCP-enabled router, rather than using the static
bypass feature, because access lists are more efficient.
The following example forces traffic from a specified client to a specified server to bypass the WAE:
WAE(config)# bypass static 10.1.17.1 172.16.7.52
The following example forces all traffic destined to a specified server to bypass the WAE:

Usage Guidelines
When enabled with the cdp enable command, CDP obtains protocol addresses of neighboring devices
and discovers the platform of those devices. It also shows information about the interfaces used by your
device. CDP is media- and protocol-independent and runs on Cisco-manufactured equipment.
Use of SNMP with the CDP MIB allows network management applications to learn the device type and
the SNMP agent address of neighboring devices and to send SNMP queries to those devices. Cisco
Discovery Protocol uses the CISCO-CDP-MIB.
Each device configured for CDP sends periodic messages, known as advertisements, to a multicast
address. The cdp timer seconds command specifies the rate at which CDP packets are sent. Each device
advertises at least one address at which it can receive SNMP messages. The advertisements also contain
Time-To-Live or hold-time information. To set the hold time, use the cdp holdtime seconds command
to specify the period of time in seconds that a receiver is to keep CDP packets. Each device also listens
to the periodic CDP messages sent by others to learn about neighboring devices.
Examples
In the following example, CDP is first enabled, the hold time is set to 10 seconds for keeping CDP
packets, and then the rate at which CDP packets are sent (15 seconds) is set:
WAE(config)# cdp enable
WAE(config)# cdp holdtime 10

(CMS) service is automatically restarted on the WAAS Central Manager if the cms service has been
enabled on the WAAS Central Manager by entering the cms enable global configuration command on
the WAAS Central Manager.
Configuring Devices Inside a NAT
In a WAAS network, there are two methods for a WAAS device that is registered with the WAAS Central
Manager (WAEs or a standby WAAS Central Manager) to obtain configuration information from the
primary WAAS Central Manager. The primary method is for the device to periodically poll the primary
WAAS Central Manager on port 443 to request a configuration update. You cannot configure this port
number. The backup method is when the WAAS Central Manager pushes configuration updates to a
registered device as soon as possible by issuing a notification to the registered device on port 443. This
method allows changes to take effect in a timelier manner. You cannot configure this port number even
when the backup method is being used. WAAS networks do not work reliably if devices registered with
the WAAS Central Manager are unable to poll the WAAS Central Manager for configuration updates.
All of the above methods become complex in the presence of Network Address Translation (NAT)
firewalls. When a WAAS device (WAEs at the edge of the network and the primary or standby WAAS
Central Managers) is inside a NAT firewall, those devices that are inside the same NAT use one IP
address (the inside local IP address) to access the device, and those devices that are outside the NAT use
a different IP address (the inside global IP address) to access the device. A centrally managed device
advertises only its inside local IP address to the WAAS Central Manager. All other devices inside the
NAT use the inside local IP address to contact the centrally managed device that resides inside the NAT.
A device that is not inside the same NAT as the centrally managed device is not able to contact it without
special configuration.
If the primary WAAS Central Manager is inside a NAT, you can allow a device outside the NAT to poll
it for getUpdate requests by configuring a static translation (inside global IP address) for the WAAS
Central Manager’s inside local IP address on its NAT, and using this address, rather than the WAAS
Central Manager’s inside local IP address, in the central-manager address ip-address global
configuration command when you register the device to the WAAS Central Manager. If a WAAS device
is inside a NAT and the WAAS Central Manager is outside the NAT, you can allow the WAAS device to
poll for getUpdate requests by configuring a static translation (inside global IP address) for the WAAS
device’s inside local address on its NAT and specifying this address in the Use IP Address field under
the NAT Configuration heading in the Device Activation window.
Note
Static translation establishes a one-to-one mapping between your inside local address and an inside
global address. Static translation is useful when a host on the inside must be accessible by a fixed address
from the outside.
Standby WAAS Central Managers
The Cisco WAAS software implements a standby WAAS Central Manager. This process allows you to
maintain a copy of the WAAS network configuration. If the primary WAAS Central Manager fails, the
standby can be used to replace the primary.
For interoperability, when a standby WAAS Central Manager is used, it must be at the same software
version as the primary WAAS Central Manager to maintain the full WAAS Central Manager
configuration. Otherwise, the standby WAAS Central Manager detects this status and does not process
any configuration updates that it receives from the primary WAAS Central Manager until the problem is
corrected.

Chapter 3 CLI Commands
(config) central-manager
Note
We recommend that you upgrade your standby WAAS Central Manager first and then upgrade your
primary WAAS Central Manager. We also recommend that you create a database backup on your primary
WAAS Central Manager and copy the database backup file to a safe place before you upgrade the
software.
Switching a WAAS Central Manager from Warm Standby to Primary
If your primary WAAS Central Manager becomes inoperable, you can manually reconfigure one of your
warm standby WAAS Central Managers to be the primary WAAS Central Manager. Configure the new
role by using the global configuration central-manager role primary command as follows:
WAE# configure
WAE(config)# central-manager role primary
This command changes the role from standby to primary and restarts the management service to
recognize the change.
Examples
Caution
If you switch a warm standby WAAS Central Manager to primary while your primary WAAS Central
Manager is still online and active, both WAAS Central Managers detect each other, automatically shut
themselves down, and disable management services. The WAAS Central Managers are switched to
halted, which is automatically saved in flash memory. For information about how to return halted WAAS
Central Managers to an online status, see the Cisco Wide Area Application Services Configuration
Guide.
Caution
When you switch a WAAS Central Manager from primary to standby, the configuration on the Central
Manager is erased. The Central Manager, after becoming a standby, will begin replicating its
configuration information from whichever Central Manager is now the primary. If standby and primary
units are not synchronized before switching roles, important configuration information can be lost.
Before you use this command, see the Cisco Wide Area Application Services Configuration Guide.
The following example specifies that the WAAS device named waas-cm is to function as the primary
WAAS Central Manager for the WAAS network:
waas-cm(config)# central-manager role primary
The following example specifies the WAE should register with the WAAS Central Manager that has an
IP address of 10.1.1.1. This command associates the WAE with the primary WAAS Central Manager so
that the WAE can be approved as a part of the WAAS network.
WAE(config)# central-manager address 10.1.1.1
The following example configures a new GUI port to access the WAAS Central Manager GUI:
WAE(config)# central-manager ui port 8550
The following example configures the WAAS Central Manager as the standby WAAS Central Manager:
WAE(config)# central-manager role standby
Switching CDM to standby will cause all configuration settings made on this CDM to be
lost.

Usage Guidelines
Note
You must deploy the WAAS Central Manager on a dedicated appliance. In the WAAS 4.0 software
release, the device mode feature was added, which allows you to deploy a WAAS device as either a
WAAS Central Manager or a WAE. Because you must deploy a WAAS Central Manager on a dedicated
appliance, a WAAS device can operate in one device mode only: either in central-manager mode or
application-accelerator mode.
A WAAS Central Manager is the device management station of a WAAS network that allows you to
centrally configure, manage, and monitor your WAEs.
By default, a WAAS device uses the application-accelerator mode, which makes it operate as a WAE.
To support the new device mode feature, the device mode global configuration command and the show
device mode EXEC commands were added in the WAAS 4.0 software release.
The set of WAAS CLI commands that are available vary based on the device mode of the WAAS device.
To enable WAAS network-related applications and services, use the cms enable global configuration
command. Use the no form of this command to disable the WAAS network.
By default, a WAAS device uses the application-accelerator mode, which makes it operate as a Wide
Area Application Engine (WAE). Before configuring network settings for your WAAS Central Managers
using the WAAS CLI, you must change the device mode to the proper device mode.
You cannot configure the WAE network module (any of the NME-WAE family of devices) as a
Central Manger.

Syntax Description
error-handling
Configures disk error handling.
reload
Reloads the disk if the system file system (SYSFS) on disk00 has problems.
remap
Sets the disk to attempt to remap disk errors automatically.
threshold
Sets the number of disk errors allowed before the disk is marked as bad.
number
Number of disk errors allowed before the disk is marked as bad (0–100).
The default is 10. A value of zero indicates that the disk should never be
marked bad.
Defaults
error-handling threshold number: 10
Command Modes
global configuration
Device Modes
application-accelerator
central-manager
Usage Guidelines
If you have a two-drive system, the RAID software protects the SYSFS from single-drive failures and
prevents applications from seeing I/O errors. With this configuration, error handling need not be
specified. For all other configurations, error handling should be specified.
To operate properly, the WAAS device must have a disk drive named disk00. The WAAS device must
also contain a disk drive that contains the first SYSFS (system file system) partition. The SYSFS
partition is used to store log files, including system logs and internal debugging logs. It may also be used
to store image files and configuration files on a WAAS device. Disk00 always contains the SYSFS
partition. When software RAID is applied, the SYSFS partitions are contained on both disk00 and
disk01. In either case, the disk00 disk and the disk that contains the first SYSFS partition are called
critical drives and are required for proper operation of the WAAS device.
When a WAE is booted and a critical disk drive is not detected at system startup time, the WAAS device
runs at a degraded state. If one of the critical disk drives becomes inoperable at run time, the WAAS
device can exhibit symptoms such as the applications malfunctioning or failing, or the WAAS device can
stop responding. You must monitor the critical disk drives on a WAAS device and report any disk drive
errors to Cisco TAC.
Cisco Wide Area Application Services Command Reference
3-286
OL-11817-01
Chapter 3 CLI Commands
(config) disk
With a WAAS device, a disk device error is defined as any of the following events:
•
A SCSI or IDE device error is printed by the Linux kernel.
•
A disk device access by an application (for example, an open(2), read(2), or write(2) system call)
fails with an EIO error code.
•
A disk device that existed at startup time is not accessible at run time.
The disk status is recorded in Flash memory (nonvolatile storage). When an error occurs on the disk drive
of a WAAS device, a message is written to the system log (syslog) if the SYSFS partition is still intact,
and an SNMP trap is generated if SNMP is configured on the WAAS device.
Specifying the Disk Error-Handling Threshold
You can define a disk device error-handling threshold on the WAAS device. If the number of disk device
errors reaches the specified threshold, the corresponding disk device is automatically marked as bad. By
default, this threshold is set to 10. The device does not stop using the bad disk device immediately; it
stops using the bad disk drive after the next reboot.
To change the default threshold, use the disk error-handling threshold global configuration command.
Specify 0 if you never want the disk drive to be marked as bad.
If the specified threshold is exceeded, the WAAS device either records this event or reboots. If the bad
disk drive is a critical disk drive, and the automatic reload feature (disk error-handling reload
command) is enabled, then the WAAS software marks the disk drive as bad, and the WAAS device is
automatically reloaded. After the WAAS device is reloaded, a syslog message and an SNMP trap are
generated.
By default, the automatic reload feature is disabled on a WAAS device. To enable the automatic reload
feature, use the disk error-handling reload global configuration command. After enabling the
automatic reload feature, use the no disk error-handling reload global configuration command to
disable it.
Examples
In the following example, an administrator configures five disk drive errors for a particular disk drive
(for example, disk00) as the maximum number of errors allowed before the disk drive is automatically
marked as bad:
WAE(config)# disk error-handling threshold 5

Usage Guidelines
The interface command contains an option for FibreChannel; however, the FibreChannel interface is
not supported for WAAS devices. The interface FibreChannel command is not documented in this
Command Reference.
To configure an interface bandwidth on a WAAS device, use the bandwidth interface configuration
command. The bandwidth is specified in megabits per second (Mbps). The 1000 Mbps option is not
available on all ports. Using this option automatically enables autosense on the interface. You cannot
change the interface speed on a WAE-7320 model that has an optical Gigabit Ethernet interface. Gigabit
Ethernet interfaces only run at 1000 Mbps for a WAE-7320. For newer models of the WAAS device (for
example, the WAE-611 or WAE-7326) that have a Gigabit Ethernet interface over copper, this restriction
Cisco Wide Area Application Services Command Reference
OL-11817-01
3-297
Chapter 3 CLI Commands
(config) interface
does not apply; you can configure these Gigabit Ethernet interfaces to run at 10, 100, or 1000 Mbps. On
newer WAAS models, the 1000-Mbps setting implies autosense. For example, you cannot configure the
Gigabit Ethernet interface to run at 1000 Mbps and half duplex.
Using the cdp enable command in global configuration mode enables CDP globally on all the interfaces.
If you want to control CDP behavior per interface, then use the cdp enable command in interface
configuration mode. The interface level control overrides the global control.
To display the interface identifiers (for example, interface GigabitEthernet 1/0), use the
show running-config or show startup-config commands. The autosense, bandwidth, full-duplex,
half-duplex, ip, and shutdown commands are listed separately in this command reference.
Configuring Multiple Secondary IP Addresses on a Single Physical Interface
Use the interface secondary global configuration command to configure more than one IP address on
the same interface. By configuring multiple IP addresses on a single interface, the WAAS device can be
present in more than one subnet. This configuration allows you to optimize the response time because
the content goes directly from the WAAS device to the requesting client without being redirected through
a router. The WAAS device becomes visible to the client because both are configured on the same subnet.
Up to four secondary addresses can be assigned to an interface. These addresses become active only after
the primary address is configured. No two interfaces can have the same IP address in the same
subnetwork. To set these secondary IP addresses, use the ip address command.
If a WAAS device has one physical interface that has multiple secondary IP addresses assigned to it, the
egress traffic uses the source IP address that is chosen by IP routing. If the secondary IP addresses of a
WAAS device in the same subnet as the primary IP address, then the egress traffic uses the primary IP
address only. In contrast, if the secondary IP addresses are in a different subnet than the primary IP
address, then the destination IP address determines which IP address on the WAAS device is used for
the egress traffic.
Configuring Interfaces for DHCP
During the initial configuration of a WAAS device, you have the option of configuring a static IP address
for the WAAS device or using interface-level DHCP to dynamically assign IP addresses to the interfaces
on the WAAS device.
If you do not enable interface-level DHCP on the WAAS device, you must manually specify a static IP
address and network mask for the WAAS device. If the WAAS device moves to another location in
another part of the network, you must manually enter a new static IP address and network mask for this
WAAS device.
An interface can be enabled for DHCP by using the ip address dhcp [client_id | hostname] interface
configuration command. The client identifier is an ASCII value. The WAAS device sends its configured
client identifier and hostname to the DHCP server when requesting network information. DHCP servers
can be configured to identify the client identifier information and the hostname information that the
WAAS device is sending and then send back the specific network settings that are assigned to the WAAS
device.
Note
You must disable autoregistration before you can manually configure an interface for DHCP.
Autoregistration is enabled by default on the first interface of the device.

Defining Interface Descriptions
You can specify a one-line description for a specific interface on a WAAS device. Use the description
text interface configuration command to enter the description for the specific interface. The maximum
length of the description text is 240 characters. This feature is supported for the Gigabit Ethernet,
port-channel, and Standby interfaces.
Note
This feature is not currently supported for the SCSI or IDE interfaces.
After you define the description for an interface, use the show EXEC commands to display the defined
interface descriptions. Enter the show interface interface type slot/port EXEC command to display the
defined description for a specific interface on the WAE.
Port-Channel (EtherChannel) Interface
EtherChannel for the WAAS software supports the grouping of two same-speed network interfaces into
one virtual interface. This grouping allows you to set or remove a virtual interface that consists of the
two integrated Gigabit Ethernet interfaces. EtherChannel also provides interoperability with Cisco
routers, switches, and other networking devices or hosts supporting EtherChannel, load balancing, and
automatic failure detection and recovery based on each interface’s current link status.
Note
You cannot use the inline Ethernet interfaces that are located on the WAE inline network adapter to form
an EtherChannel.
InlineGroup Interface
An InlineGroup interface is a logical grouping of a pair of Ethernet ports that are physically contained
in the optional 4-port inline network adapter card. The inline network adapter is supported on all WAAS
appliance platforms beginning with the WAAS 4.0.7 release. You can have up to two InlineGroup
interfaces, which allows for two bypass-enabled paths for traffic to pass through the WAE appliance,
making multiple-router deployments possible. The InlineGroup interfaces provide failover capability
and can be assigned to any desired set of VLANs. (For examples of InlineGroup interface configurations,
see the “(config-if) inline” command.)
InlinePort Interface
The InlinePort interfaces are a set of four Ethernet ports that are physically contained in the optional
4-port inline adapter card. InlinePorts are identified by slot number, InlineGroup number, and interface
direction (either as the LAN-facing or WAN-facing interface). You can configure the InlinePort interface
for link speed (bandwidth or autosense) and mode of operation (half-duplex or full-duplex).
Note
Examples
We strongly recommend that you do not use half-duplex connections on the WAE or on routers, switches,
or other devices.

Usage Guidelines
To define a default gateway, use the ip default-gateway command. Only one default gateway can be
configured. To remove the IP default gateway, use the no form of this command. The WAAS device uses
the default gateway to route IP packets when there is no specific route found to the destination.

OL-11817-01
Chapter 3 CLI Commands
(config) ip
To define a default domain name, use the ip domain-name command. To remove the IP default domain
name, use the no form of this command. Up to three domain names can be entered. If a request arrives
without a domain name appended in its hostname, the proxy tries to resolve the hostname by appending
name1, name2, and name3 in that order until one of these names succeeds.
The WAAS device appends the configured domain name to any IP hostname that does not contain a
domain name. The appended name is resolved by the DNS server and then added to the host table. The
WAAS device must have at least one domain name server specified for hostname resolution to work
correctly.
To specify the address of one or more name servers to use for name and address resolution, use the
ip name-server ip-addresses command. To disable IP name servers, use the no form of this command.
For proper resolution of the hostname to the IP address or the IP address to the hostname, the WAAS
device uses DNS servers. Use the ip name-server command to point the WAAS device to a specific DNS
server. You can configure up to eight servers.
Path MTU autodiscovery discovers the MTU and automatically sets the correct value. Use the ip
path-mtu-discovery enable command to start this autodiscovery utility. By default, this feature is
enabled. When this feature is disabled, the sending device uses a packet size that is smaller than
576 bytes and the next hop MTU. Existing connections are not affected when this feature is turned on or
off.
The WAAS software supports IP Path MTU Discovery, as defined in RFC 1191. When enabled, Path
MTU Discovery discovers the largest IP packet size allowable between the various links along the
forwarding path and automatically sets the correct value for the packet size. By using the largest MTU
that the links will bear, the sending device can minimize the number of packets that it must send.
Note
IP Path MTU Discovery is useful when a link in a network goes down, forcing the use of another,
different MTU-sized link. IP Path MTU Discovery is also useful when a connection is first being
established and the sender has no information at all about the intervening links.
IP Path MTU Discovery is initiated by the sending device. If a server does not support IP Path MTU
Discovery, the receiving device will have no mechanism available to avoid fragmenting datagrams
generated by the server.
Use the ip route command to add a specific static route for a network or host. Any IP packet designated
for the specified destination uses the configured route.
To configure static IP routing, use the ip route command. To remove the route, use the no form of this
command. Do not use the ip route 0.0.0.0 0.0.0.0 command to configure the default gateway; use the
ip default-gateway command instead.
Examples
The following example configures a default gateway for the WAAS device:
WAE(config)# ip default-gateway 192.168.7.18
The following example disables the default gateway:
WAE(config)# no ip default-gateway

Chapter 3 CLI Commands
(config) ip access-list
Usage Guidelines
Note
Use access lists to control access to specific applications or interfaces on a WAAS device. An access
control list consists of one or more condition entries that specify the kind of packets that the WAAS
device will drop or accept for further processing. The WAAS device applies each entry in the order in
which it occurs in the access list, which by default is the order in which you configured the entry.
IP ACLs that are defined on a router take precedence over the IP ACLs that are defined on the WAE. IP
ACLs that are defined on a WAE take precedence over the WAAS application definition policies that are
defined on the WAE.
Within ACL configuration mode, you can use the editing commands (list, delete, and move) to display
the current condition entries, to delete a specific entry, or to change the order in which the entries will
be evaluated. To return to global configuration mode, enter exit at the ACL configuration mode prompt.
To create an entry, use a deny or permit keyword and specify the type of packets that you want the
WAAS device to drop or to accept for further processing. By default, an access list denies everything
because the list is terminated by an implicit deny any entry. Therefore, you must include at least one
permit entry to create a valid access list.
After creating an access list, you can include the access list in an access group using the access-group
command, which determines how the access list is applied. You can also apply the access list to a specific
application using the appropriate command. A reference to an access list that does not exist is the
equivalent of a permit any condition statement.
To work with access lists, enter either the ip access-list standard or ip access-list extended global
configuration command. Identify the new or existing access list with a name up to 30 characters long
beginning with a letter, or with a number. If you use a number to identify a standard access list, it must
be between 1 and 99; for an extended access list, use a number from 100 to 199. You must use a standard
access list for providing access to the SNMP server or to the TFTP gateway/server. However, you can
use either a standard access list or an extended access list for providing access to the WCCP application.
After you identify the access list, the CLI enters the appropriate configuration mode and all subsequent
commands apply to the specified access list. The prompt for each configuration mode is shown in the
following examples.
WAE(config)# ip access-list standard test
WAE(config-std-nacl)# exit
WAE(config)# ip access-list extended test2
WAE(config-ext-nacl)#
Examples
The following commands create an access list on the WAAS device. You create this access list to allow
the WAAS device to accept all web traffic that is redirected to it, but limits host administrative access
using SSH:

Usage Guidelines
All Windows 2000 domains are also Kerberos realms. Because the Windows 2000 domain name is also
a DNS domain name, the Kerberos realm name for the Windows 2000 domain name is always in
uppercase letters. This capitalization follows the recommendation for using DNS names as realm names
in the Kerberos Version 5 protocol document (RFC-1510) and affects only interoperability with other
Kerberos-based environments.

(config) kerberos
The KDC server and all hosts with Kerberos authentication configured must interact within a 5-minute
window or authentication will fail. All hosts, especially the KDC, should be running NTP. For
information about configuring NTP, see the “(config) ntp” command.
The KDC server and Admin server must have the same IP address. The default port number for both
servers is port 88.
The kerberos command modifies the krb5.conf file.
Examples
The following example shows how to configure the WAAS device to authenticate with a specified KDC
in a specified Kerberos realm. The configuration is then verified.
WAE(config)# kerberos ?

(config) kernel
(config) kernel
To enable access to the kernel debugger (kdb), use the kernel kdb global configuration command. Once
enabled, kdb is automatically activated if kernel problems occur, or you can manually activate it from
the local console for the WAAS device by pressing the required key sequence. To disable access to the
kernel debugger, use the no form of the command.
kernel kdb
Syntax Description
This command has no arguments or keywords.
Defaults
The kernel debugger is disabled by default.
Command Modes
global configuration
Device Modes
application-accelerator
central-manager
Usage Guidelines
Once enabled, kdb is automatically activated when kernel problems occur. Once activated, all normal
functioning of the WAAS device is suspended until kdb is manually deactivated. The kdb prompt looks
like this:
[0]kdb>
To deactivate kdb, enter go at the kdb prompt. If kdb was automatically activated because of kernel
problems, the system generates a core dump and restarts. If you activated kdb manually for diagnostic
purposes, the system resumes normal functioning in whatever state it was when you activated kdb. In
either case, if you enter reboot, the system restarts and normal operation resumes.
kdb is disabled by default and you must enter the kernel kdb command in global configuration mode to
enable it. If kdb has been previously enabled, you can enter the no kernel kdb global configuration
command to disable it. When kdb is enabled, you can activate it manually from the local console by
pressing Ctrl-_ followed by Ctrl-B.
The rationale for disabling the kernel debugger is as follows: the WAAS device is often unattended at
many sites, and it is desirable for the WAAS device to automatically reboot after generating a core dump
instead of requiring user intervention. Disabling the kernel debugger allows automatic recovery.
Examples
The following example enables, and then disables, access to the kernel debugger:
WAE(config)# kernel kdb
WAE(config)# no kernel kdb

Usage Guidelines
Use the logging command to set specific parameters of the system log file. System logging is always
enabled internally. By default, system logging is enabled on a WAAS device. The system log file is
located on the SYSFS partition at /local1/syslog.txt. This file contains authentication entries, privilege
levels, and administrative details.
WAAS supports filtering multiple syslog messages for a single failed section on SCSI disks and SATA
disks.
To configure the WAAS device to send varying levels of event messages to an external syslog host, use
the logging host option. Logging can be configured to send various levels of messages to the console
using the logging console priority option.
The no logging disk recycle size command sets the file size to the default value. Whenever the current
log file size surpasses the recycle size, the log file is rotated. The log file cycles through at most five
rotations, and they are saved as [log file name].[1-5] under the same directory as the original log. The
rotated log file is the one configured using the logging disk filename command.
Configuring System Logging to Remote Syslog Hosts
You can configure a WAAS device to send varying levels of messages to up to four remote syslog hosts.
Use the logging host hostname global configuration command as follows:
WAE(config)# [no] logging host hostname [priority priority-code | port port |rate-limit
limit]
where
•
hostname is the hostname or IP address of the remote syslog host. Specify up to four remote syslog
hosts. To specify more than one syslog host, use multiple command lines; specify one host per
command.

(config) logging
•
Note
Examples
priority-code is the severity level of the message that should be sent to the specified remote syslog
host. The default priority-code is “warning” (level 4). Each syslog host is capable of receiving a
different level of event messages.
You can achieve syslog host redundancy by configuring multiple syslog hosts on the WAAS device and
assigning the same priority code to each configured syslog host (for example, assigning a priority code
of “critical” level 2 to syslog host 1, syslog host 2, and syslog host 3).
•
port is the destination port of the remote syslog host to which the WAAS device is to send the
messages. The default port is port 514.
•
rate-limit specifies the number of messages that are allowed to be sent to the remote syslog host per
second. To limit bandwidth and other resource consumption, messages to the remote syslog host can
be rate limited. If this limit is exceeded, the specified remote syslog host drops the messages. There
is no default rate limit, and by default all syslog messages are sent to all of the configured syslog
hosts. If the rate limit is exceeded, a “message of the day” (motd) will be printed for any CLI EXEC
shell login.
In the following example, the WAAS device is configured to send messages that have a priority code of
“error” (level 3) to the console:
WAE(config)# logging console priority error
In the following example, the WAAS device is configured to disable sending of messages that have a
priority code of “error” (level 3) to the console:
WAE(config)# no logging console error
In the following example, the WAAS device is configured to send messages that have a priority code of
“error” (level 3) to the remote syslog host that has an IP address of 172.31.2.160:
WAE(config)# logging host 172.31.2.160 priority error

Usage Guidelines
The port-channel load-balance command configures one of three load-balancing algorithms and
provides flexibility in choosing interfaces when an Ethernet frame is sent. The round-robin option
allows evenly balanced usage of identical network interfaces in a channel group. Because this command
takes effect globally, if two channel groups are configured, they must use the same load-balancing
option.
Examples

Standby
Selects a standby group as the primary interface of the WAAS device.
group_num
Standby group number 1–4.
Defaults
The default primary interface is the Gigabit Ethernet 1/0 interface. If this is not configured, then the first
operational interface on which a link beat is detected becomes the default primary interface. Interfaces
with lower-number IDs are polled first (for example, Gigabit Ethernet 1/0 is checked before 2/0). The
Gigabit Ethernet interfaces are polled before the Port Channel interfaces.
Command Modes
global configuration
Device Modes
application-accelerator
central-manager
Usage Guidelines
The primary-interface global configuration command permits the administrator to specify the primary
interface for the WAAS device.
The primary interface can be changed without disabling the WAAS device. To change the primary
interface, reenter the command string and specify a different interface.
Note
If you use the restore factory-default preserve basic-config command, the configuration for the
primary interface is not preserved. If you want to reenable the WAAS device after using the restore
factory-default preserve basic-config command, make sure to reconfigure the primary interface after
the factory defaults are restored.
Setting the primary interface to be a Standby group does not imply that Standby functionality is
available. You must configure relevant Standby interfaces using the interface standby global
configuration command.

Chapter 3 CLI Commands
(config) print-services
From the WAAS CLI, you can start and stop WAAS print services, configure a print services
administrative group, and debug the print spooler. WAAS print services provide an alternative to
Windows print services.
Starting and Stopping Print Services
When the print-services enable command is executed, the following sequence of events occurs:
•
The node manager starts the CUPS process (cupsd), checking every second for an updated
timestamp in the printcap file.
CUPS must start within 30 seconds or print services are not enabled, and a “CUPS fails to start”
message is logged by the node manager.
•
The node manager starts the Samba process (smbd).
If Samba could not be started, a “Samba fails to start” message is logged by the node manager. CUPS
is not stopped.
•
Success messages are logged by the node manager.
•
The DataServer value (cfg/print-services/enable) is set to one.
Stopping print services is accomplished using the no print-services enable command. Entering this
command causes the following sequence of events:
•
The node manager stops the Samba process (smbd).
•
The node manager stops the CUPS process (cupsd).
•
The corresponding DataServer value is set to zero.
Configuring the Print Services Administrative Group
You can define a set of administrators to have control over WAAS print services on a particular
Edge WAE using the print-services admin-group command. When this command is entered, the
following events occur:
•
The smb.conf file is updated with the specified administrative group.
If the update fails, and the print services administrative group can be returned to its original value,
the error message “Failed to configure print-services admin group” is displayed. If the update fails,
and the print services administrative group cannot be returned to its original value, two error
messages, “Failed to configure print-services admin group.” and “Failed to revert back the
print-services admin group changes.” are displayed.
•
The cupsd.conf file is updated with the specified administrative group.
If the update fails, the old setting is restored, the changes to the smb.conf file are reverted, and the
error message: “Failed to configure print-services admin group” is displayed. If the update fails and
the old setting cannot be restored, two error messages, “Failed to configure print-services admin
group.” and “Failed to revert back the print-services admin group changes.” are displayed.
•
The DataServer value (/cfg/print-services/administrators) is updated with the specified
administrative group.
If setting the DataServer value fails, both configurations of smb.conf and cupsd.conf are reverted,
and an error message is displayed.
Cisco Wide Area Application Services Command Reference

OL-11817-01
Chapter 3 CLI Commands
(config) print-services
You can delete a print services administrative group using the no print-services admin-group
command. When this command is executed, the following events occur:
•
The smb.conf setting is cleared.
If the clear fails, the old setting is restored and the error message “Failed to configure print-services
admin group” is displayed. If the clear fails and the old setting cannot be restored, two error
messages, “Failed to configure print-services admin group.” and “Failed to revert back the
print-services admin group changes.” are displayed.
•
The cupsd.conf file is modified to clear the admin group setting.
If the clear fails, the old setting is restored, and changes in the smb.conf are reverted, the error
message “Failed to configure print-services admin group” is displayed. If the clear fails and the old
setting cannot be restored, two error messages, “Failed to configure print-services admin group.”
and “Failed to revert back the print-services admin group changes.” are displayed.
•
The corresponding DataServer value is cleared.
If clearing the DataServer value fails, both configurations of smb.conf and cupsd.conf are reverted,
and an error message is displayed.
The Samba and CUPS processes must be manually restarted for this change to take effect.
Examples
The following example enables print services on a WAAS device:
WAE(config)# print-services enable
The following example adds a print services administrative group called printAdmins:
WAE(config)# print-services admin-group printAdmins
The new print-services administrator group is configured successfully. Please restart
print services for the change to take effect.
WAE(config)# no print-services enable
WAE(config)# print-services enable
The following example removes the print service’s administrative group from the WAAS device:
WAE(config)# no print-services admin-group printAdmins
The print-services administrator group is removed successfully. Please restart print
services for the change to take effect.

retransmit retries: 2
timeout seconds: 5
Command Modes
global configuration
Device Modes
application-accelerator

Usage Guidelines
RADIUS is a client/server authentication and authorization access protocol used by a NAS to
authenticate users attempting to connect to a network device. The NAS functions as a client, passing user
information to one or more RADIUS servers. The NAS permits or denies network access to a user based
on the response it receives from one or more RADIUS servers. RADIUS uses UDP for transport between
the RADIUS client and server.
You can configure a RADIUS key on the client and server. If you configure a key on the client, it must
be the same as the one configured on the RADIUS servers. The RADIUS clients and servers use the key
to encrypt all RADIUS packets transmitted. If you do not configure a RADIUS key, packets are not
encrypted. The key itself is never transmitted over the network.

OL-11817-01
Chapter 3 CLI Commands
(config) radius-server
Note
For more information about how the RADIUS protocol operates, refer to RFC 2138, Remote
Authentication Dial In User Service (RADIUS).
RADIUS authentication usually occurs when an administrator first logs in to the WAAS device to
configure the WAE for monitoring, configuration, or troubleshooting purposes.
RADIUS authentication is disabled by default. You can enable RADIUS authentication and other
authentication methods at the same time. You can also specify which method to use first. (See the
“(config) authentication” command.)
Examples
The following example specifies a RADIUS server, specifies the RADIUS key, and accepts retransmit
defaults. Configuration can be verified with the show radius-server command.

Usage Guidelines
The smb.conf file contains a variety of print-related parameters. The global parameters apply to the
server as a whole. Service level parameters that define default settings for all other sections and shares
are included in this set of parameters. This avoids the need to set the same value repeatedly. You can
override these globally set share settings and specify other values for each individual section or share.
The print$ parameters apply to the printers. The printers parameters apply to the shares. They make it
possible to share all printers with minimal configuration. These parameters apply as default to all
printers.

(config) snmp-server community
To enable the SNMP agent on a WAAS device and to set up the community access string to permit access
to the SNMP agent, use the snmp-server community global configuration command. To disable the
SNMP agent and remove the previously configured community string, use the no form of this command.
snmp-server community string [group groupname | rw]
Syntax Description
string
Community string that acts like a password and permits access to the SNMP agent.
Supports up to a maximum of 64 characters.
group
(Optional) Specifies the group to which the community string belongs.
groupname
Name of the group. Supports up to a maximum of 64 characters.
rw
(Optional) Enables read-write access to this community string.
Defaults
The SNMP agent is disabled and a community string is not configured. When configured, an SNMP
community string by default permits read-only access to all objects.
Usage Guidelines
The SNMP community string is used as a password for authentication when accessing the SNMP agent
on the WAE. To be authenticated, the Community Name field of any SNMP message sent to the WAAS
device must match the SNMP community string defined on the WAAS device.
The SNMP agent on the WAAS device is enabled when an SNMP community string is defined on the
WAAS device. The maximum number of SNMP communities that can be created is 10.
The snmp-server community string global configuration command provides view-based access control
for SNMPv1, SNMPv2c, and SNMPv3, yet continues to provide backward compatibility between
different versions.
Tip
Any SNMP message sent to the WAAS device must have the “Community Name” field of the
message match the community string defined here to be authenticated.
It is possible to configure a community string that grants access to only part of the MIB subtree. To
provide backward compatibility with previous versions of this command, a default read group or default
write group (if the rw option is specified on the command line) is associated with the community string
if no group name is specified. Both of these default groups are hidden from users and not displayed in
the configuration file or in the show snmp group EXEC command, but are created during initialization
of the SNMP agent.

Usage Guidelines
You can configure a WAAS device to generate an SNMP trap for a specific alarm condition. You can
configure the generation of SNMP alarm traps on the WAAS device based on the following:
•
The severity of the alarm (critical, major, or minor)
•
The action (the alarm is raised or cleared).
In the WAAS software release, the following six generic alarm traps are available in the
CISCO-CONTENT-ENGINE-MIB.
Note
Name of Alarm Trap
Severity
Action
cceAlarmCriticalRaised
Critical
Raised
cceAlarmCriticalCleared
Critical
Cleared
cceAlarmMajorRaised
Major
Raised
cceAlarmMajorCleared
Major
Cleared
cceAlarmMinorRaised
Minor
Raised
cceAlarmMinorCleared
Minor
Cleared
By default, these six general alarm traps are disabled.
These six general alarm traps provide SNMP and Node Health Manager integration. Each of these six
alarm traps can be enabled or disabled through the WAAS CLI.
To configure traps, you must enter the snmp-server enable traps command. If you do not enter an
snmp-server enable traps command, no traps are sent.
The snmp-server enable traps command is used in conjunction with the snmp-server host command.
Use the snmp-server host command to specify which host or hosts receive SNMP traps. To send traps,
you must configure at least one host using the snmp-server host command.
For a host to receive a trap, both the snmp-server enable traps command and the snmp-server host
command for that host must be enabled.
In addition, SNMP must be enabled with the snmp-server community command.
To disable the sending of the MIB-II SNMP authentication trap, you must enter the command
no snmp-server enable traps snmp authentication.
Examples
The following example enables the WAAS device to send all traps to the host 172.31.2.160 using the
community string public:
WAE(config)# snmp-server enable traps
WAE(config)# snmp-server host 172.31.2.160 public
The following example disables all traps:

When defining SNMP users for WAAS devices, note the following:
•
If the SNMPv3 protocol is going to be used for SNMP requests, you must define at least one
SNMPv3 user account on the WAAS device for the WAAS device to be accessed through SNMP.
•
A group defined with the SNMPv1 or SNMPv2c security model should not be associated with
SNMP users; they should only be associated with the community strings.
In the following example, an SNMPv3 user account is created on the WAAS device. The SNMPv3 user
is named acme and belongs to the group named admin. Because this SNMP user account has been set up
with no authentication password, the SNMP agent on the WAAS device does not perform authentication
on SNMP requests from this user.
WAE(config)# snmp-server user acme admin

(config) sshd
(config) sshd
To enable the SSH daemon on a WAAS device, use the sshd command in global configuration mode. To
disable the SSH daemon on a WAAS device, use the no form of this command.
sshd {allow-non-admin-users | enable | password-guesses number | timeout seconds |
version {1 | 2}}
Syntax Description
allow-non-admin-users
Allows nonadministrative users to gain SSH access to the chosen device
(or device group). By default, this option is disabled.
Note
enable
Enables the SSH daemon on a WAAS device.
password-guesses
Specifies the number of allowable password guesses per connection.
number
Maximum number of incorrect password guesses allowed (1–99). (The
default is 3.)
timeout
Configures the number of seconds for which an SSH session will be
active during the negotiation (authentication) phase between client and
server before it times out.
Note
Defaults
Nonadministrative users are non-superuser administrators. All
non-superuser administrators only have restricted access to a
WAAS device because their login accounts have a privilege level
of 0. Superuser administrators have full access to a WAAS device
because their login accounts have the highest level of privileges,
a privilege level of 15.
If you have established an SSH connection to the WAAS device
but have not entered the username when prompted at the login
prompt, the connection will be terminated by the WAAS device
if the grace period expires even after successful login.
seconds
SSH login grace time value in seconds (1–99999). (The default is 300.)
version
Configures the SSH version to be supported on the WAAS device.
1
Specifies that SSH Version 1 is supported on the WAAS device.
2
Specifies that SSH Version 2 is supported on the WAAS device.
By default, the SSH daemon is disabled on a WAAS device. If you use the sshd enable command to
enable the SSH daemon on a WAAS device, the following default settings are used:
password-guesses number: 3 guesses
timeout seconds: 300 seconds

Chapter 3 CLI Commands
(config) sshd
Usage Guidelines
SSH enables login access to the WAAS device through a secure and encrypted channel. SSH consists of
a server and a client program. Like Telnet, you can use the client program to remotely log on to a machine
that is running the SSH server, but unlike Telnet, messages transported between the client and the server
are encrypted. The functionality of SSH includes user authentication, message encryption, and message
authentication.
Before you enable the sshd command, use the ssh-key-generate command to generate a private and a
public host key, which the client programs use to verify the server’s identity.
Although the sshd password-guesses command specifies the number of allowable password guesses
from the SSH server side, the actual number of password guesses for an SSH login session is determined
by the combined number of allowable password guesses of the SSH server and the SSH client. Some
SSH clients limit the maximum number of allowable password guesses to three (or to one in some cases),
even though SSH server side allows more than this number of guesses.
When sshd password-guesses is entered, specifying n allowable password guesses, certain SSH clients
interpret this number as n+1. For example, when configuring the number of guesses to two by issuing
the command sshd password-guesses 2 for a particular device, SSH sessions from some SSH clients
will allow three password guesses.
You can enable both SSH Version 1 and Version 2, or you can enable one version and not the other. When
you enable the SSH daemon using the sshd enable global configuration command, support for both SSH
Version 1 and SSH Version 2 is enabled. If you want the WAAS device to support only one version of
SSH (for example SSH version 2), you must disable the other version. For example, to disable SSH
Version 1, enter the no sshd version 1 command.
If the SSH daemon is currently enabled on a WAAS device, at least one version of SSH must be enabled
on the device. Before you can disable both versions of SSH, you must enter the no sshd enable command
to disable the SSH daemon on the WAAS device. If you attempt to disable both versions of SSH before
you have disabled the SSH daemon, the following message will appear on your console informing you
that you must disable the SSH daemon before you can disable both versions of SSH:
WAE(config)# no sshd version 1
WAE(config)# no sshd version 2
Atleast SSHv1 or SSHv2 must be enabled with sshd enabled.
Disable sshd to disable both SSHv1 and SSHv2.
Did not update ssh version support. Please retry.
When support for both SSH version 1 and SSH version 2 are enabled in the WAAS device, the show
running-config EXEC command output does not display any SSHD configuration.
If you have disabled the support for one version of SSH, the show running-config EXEC command
output contains the following line:
no sshd version version_number
Note
The Telnet daemon can still be used with the WAAS device. SSH does not replace Telnet.

ssh-key-generate [key-length length]
Syntax Description
key-length
(Optional) Configures the length of the SSH key.
length
Number of bits to create an SSH key (512–2048).
Defaults
key-length length: 1024 bits
Command Modes
global configuration
Device Modes
application-accelerator
central-manager
Usage Guidelines
Before you enter the sshd enable command, enter the ssh-key-generate command to generate a private
and a public host key, which the client programs use to verify a server’s identity.
When you use an SSH client and log in to a WAAS device, the public key for the SSH daemon that is
running on the device is recorded in the client machine known_hosts file in your home directory. If you
subsequently regenerate the host key by specifying the number of bits in the key-length command
option, you must delete the old public key entry associated with the WAAS device in the known_hosts
file before running the SSH client program to log in to the WAAS device. When you use the SSH client
program after deleting the old entry, the known_hosts file is updated with the new SSH public key for
the WAAS device.
Examples
The following example generates an SSH public key and then enables the SSH daemon on the WAAS
device:
WAE(config)# ssh-key-generate
Ssh host key generated successfully
Saving the host key to box ...
Host key saved successfully
WAE(config)# sshd enable

| timeout seconds}
Syntax Description
Defaults
host
Specifies a server address.
hostname
Hostname of the TACACS+ server.
ip-address
IP address of the TACACS+ server.
primary
(Optional) Sets the server as the primary server.
key
Sets the security word.
keyword
Keyword. An empty string is the default.
password ascii
Specifies ASCII as the TACACS+ password type.
retransmit
Sets the number of times that requests are retransmitted to a server.
retries
Number of retry attempts allowed (1–3). The default is 2 retry attempts.
timeout
Sets the number of seconds to wait before a request to a server is timed out.
seconds
Timeout in seconds (1–20). The default is 5 seconds.
keyword: none (empty string)
timeout seconds: 5
retries: 2
password: The default password type is PAP.
Command Modes
global configuration
Device Modes
application-accelerator
central-manager
Usage Guidelines
One primary and two backup TACACS+ servers can be configured on a WAAS device; authentication is
attempted on the primary server first, then on the others in the order in which they were configured. The
primary server is the first server configured unless another is explicitly specified as primary with the
tacacs host hostname primary command.
TACACS+ uses the standard port (port 49) for communication, based on the specified service. Using the
tacacs command, configure the TACACS+ key, number of retransmits, server hostname or IP address,
and timeout.
To enable user authentication with a TACACS+ server, use the authentication global configuration
command. (See the “(config) authentication” command.)
Cisco Wide Area Application Services Command Reference
3-374
OL-11817-01
Chapter 3 CLI Commands
(config) tacacs
The TACACS+ remote database can also be used to maintain login and configuration privileges for
administrative users. The tacacs host command allows you to configure the network parameters required
to access the remote database.
Use the tacacs key command to specify the TACACS+ key, used to encrypt the packets transmitted to
the server. This key must be the same as the one specified on the server daemon. The maximum number
of characters in the key should not exceed 99 printable ASCII characters (except tabs). An empty key
string is the default. All leading spaces are ignored; spaces within and at the end of the key string are not
ignored. Double quotes are not required even if there are spaces in the key, unless the quotes themselves
are part of the key.
The tacacs timeout is the number of seconds that the WAAS device waits before declaring a timeout on
a request to a particular TACACS+ server. The range is from 1 to 20 seconds, with 5 seconds as the
default. The number of times that the WAAS device repeats a retry-timeout cycle before trying the next
TACACS+ server is specified by the tacacs retransmit command. The default is two retry attempts.
Three unsuccessful login attempts are permitted. TACACS+ logins may appear to take more time than
local logins depending on the number of TACACS+ servers and the configured timeout and retry values.
Use the tacacs password ascii command to specify the TACACS+ password type as ASCII. The default
password type is PAP (Password Authentication Protocol).When the no tacacs password ascii
command is used to disable the ASCII password type, the password type is once again reset to PAP.
The TACACS+ client can send different requests to the server for user authentication. The client can
send a TACACS+ request with the PAP password type. In this scenario, the authentication packet
includes both the username and password of the user. The server must have an appropriately configured
account for the user.
Alternatively, the client can send a TACACS+ request with the ASCII password type as another option.
In this scenario, the authentication packet includes the username only and waits for the server response.
Once the server confirms that the account exists for a user, the client sends another Continue request with
the password of the user. The authentication server must have an appropriately configured account for
the user to support either type of password.
Examples
The following example configures the key used in encrypting packets:
WAE(config)# tacacs key human789
The following example configures the host named spearhead as the primary TACACS+ server:
WAE(config)# tacacs host spearhead primary
The following example sets the timeout interval for the TACACS+ server:
WAE(config)# tacacs timeout 10
The following example sets the number of times that authentication requests are retried (retransmitted)
after a timeout:
WAE(config)# tacacs retransmit 5
The following example shows the password type to be PAP by default:

Note
You can adjust the TCP stack parameters to maximize cache performance and throughput of HTTP
streams over TCP end to end. The relevant TCP parameters to maximize cache performance and
throughput include the ability to tune timeout periods, client and server receive and send buffer sizes,
and TCP window scaling behavior.
Because of the complexities involved in TCP parameters, care is advised in tuning these parameters. In
nearly all environments, the default TCP settings are adequate. Fine tuning of TCP settings is for
network administrators with adequate experience and full understanding of TCP operation details. See
the Cisco Wide Area Application Services Configuration Guide for more information.
Use the tcp keepalive-probe-cnt global configuration command to specify how many times the WAAS
device should attempt to connect to the device before closing the connection. The count can be from 1
to 10. The default is 4 attempts.
Use the tcp keepalive-probe-interval global configuration command to specify how often the WAAS
device is to send out a TCP keepalive. The interval can be from 1 to 120 seconds. The default is 75
seconds.

Usage Guidelines
Use the tfo auto-discovery blacklist hold-time command to adjust the blacklist hold time for the TFO
auto-discovery feature. With auto-discovery, the WAE keeps track of origin servers (such as those
servers behind firewalls) that cannot receive optioned TCP packets and learns not to send out TCP
packets with options to these blacklisted servers. When a server IP address is added to the blacklist, it
remains on the blacklist for the configured number of minutes. After the hold time expires, subsequent
connection attempts will again include TCP options so that the WAE can redetermine if the server can
receive them. Resending TCP options periodically is useful because network packet loss could cause a
server to be blacklisted erroneously.

Usage Guidelines
Depending upon where the sysfs is mounted, transactions are logged to a working log on the local disk
in one of these files:
•
/local1/logs/working.log
•
/local2/logs/working.log
When you enable transaction logging, you can specify the interval at which the working log should be
cleared by moving the data to an archive log. The archive log files are located on the local disk in the
directory /local1/logs/ or /local2/logs/, depending upon where the sysfs is mounted.
Because multiple archive files are saved, the filename includes the time stamp when the file was
archived. Because the files can be exported to an FTP/SFTP server, the filename also contains the IP
address of this WAE.
The archive file name use this format:
celog_IPADDRESS_YYYYMMDD_HHMMSS.txt.
You can monitor transaction logs in real-time for particular errors such as authentication errors. By
sending HTTP transaction log messages to a remote syslog server, you can monitor the remote syslog
server for HTTP request authentication failures in real-time. This real-time transaction log feature allows
you to monitor transaction logs in real-time for particular errors such as HTTP request authentication
errors. The existing transaction logging to the local file system remains unchanged.
For this purpose, you must configure the WAE to send transaction log messages to a remote syslog server
using UDP as the transport protocol. Because UDP is an unreliable transport protocol, message transport
to a remote syslog host is not reliable and you must monitor the syslog messages received at the remote

Chapter 3 CLI Commands
(config) transaction-logs
syslog server. You can limit the rate at which the transaction logging module is allowed to send messages
to the remote syslog server. The format of the syslog message is in standard syslog message format with
the transaction log message as the payload of the syslog message.
Real-time transaction logging to a remote syslog server uses the standard syslog message format with
the message payload as the transaction log entry. A new syslog error identifier is defined for this type of
real-time transaction log message. You can configure a WAE to send transaction log messages in
real-time to one remote syslog host. The message format of the transaction log entry to the remote syslog
host is the same as in the transaction log file and prepended with Cisco’s standard syslog header
information.
The following is an example of the format of the real-time syslog message sent from the transaction
logging module (WAE) to the remote syslog host:
fac-pri Apr 22 20:10:46 ce-host cache: %CE-TRNSLG-6-460012: translog formatted msg
The fields in the message are described as follows:
•
fac-pri denotes the facility parameter and priority for transaction log messages encoded (as in
standard syslog format) as a 32-bit decimal value between 0 and 1023 (0x0000 and 0x03FF). The
least significant 3 bits denote priority (0-7) and the next least significant 7 bits denote facility
(0-127).
The facility parameter used by the transaction logging module when a real-time transaction log
message is logged to the remote syslog host is user. The same facility is sent to the remote syslog
host unless you configure a different facility parameter for transaction logging. The priority field is
always set to LOG_INFO for real-time transaction log messages.
In the above example, the default value of fac-pri is 14 (0x000E) where facility = user (LOG_USER
(1)) and priority = LOG_INFO (6).
•
The next field in the message is the date, which follows the format as shown in the above example.
•
ce-host is the hostname or IP of the WAE that is sending the message.
•
cache is the name of the process on the WAE that is sending the message.
•
%CE-TRNSLG-6-460012 is the Cisco standard formatted syslog header on the WAE for a real-time
transaction log message. This identifier indicates a priority level of 6, which denotes informational
messages.
Note
•
The WAAS system syslog messages report communication errors with the remote syslog
host that is configured for transaction logging. These syslog messages are in the error
message range: %CE-TRNSLG-6-460013 to %CE-TRNSLG-3-460016. The last error
message (%CE-TRNSLG-3-460016), shows level “3” (for error-level messages) instead of
“6” (for information-level messages). Information-level messages are reported when
messages are dropped due to rate limiting and the number of dropped messages are reported.
For more information about these syslog messages, see the Cisco WAAS System Messages
Reference.
translog formatted msg is the transaction log message as it appears in the transaction log file.
Note
The total length of the real-time syslog message is 1024 characters. If the actual transaction
log entry exceeds this limit, it is truncated.
When the remote syslog server logs this message to a file, the format appears as follows:
Apr 22 20:10:46 ce-host cache: %CE-TRNSLG-6-460012: translog formatted msg

where ce-host is the host name of the WAE that sent the real-time transaction log message to the remote
syslog server.
The configuration of host settings for transaction logs is identical to the configuration settings for syslog
messages except that you need not specify the priority level of the message for real time transaction logs.
All messages are associated with the priority level of 6 (LOG_INFO). You are not required to filter
messages based on priority levels.

(config) username
Usage Guidelines
A system administrator can log in to a WAAS device that is functioning as a Core or Edge WAE through
the console port or the WAE Device Manager GUI. An administrator can log in to the WAAS Central
Manager through the console port or the WAAS Central Manager GUI.
When the system administrator logs in to a WAAS device before authentication and authorization have
been configured, the administrator can access the WAAS device by using the predefined superuser
account (the predefined username is admin and the predefined password is default). When you log in to
a WAAS device using this predefined superuser account, you are granted access to all the WAAS services
and entities in the WAAS system.
After you have initially configured your WAAS devices, we strongly recommend that you immediately
change the password for the predefined superuser account (the predefined username is admin, the
password is default, and the privilege level is superuser, privilege level 15) on each WAAS device.
If the predefined password for this superuser account has not been changed on a WAAS device, the
following message is displayed each time you use this superuser account to log in to the WAAS CLI:
Device is configured with a (well known) default username/password
for ease of initial configuration. This default username/password
should be changed in order to avoid unwanted access to the device.
System Initialization Finished.
waas-cm#
If the predefined password for this superuser account has not been changed on a WAAS Central Manager,
a dialog box is also displayed each time you use this superuser account to log in to the WAAS
Central Manager GUI.
Note
We strongly recommend that you use the WAAS Central Manager GUI instead of the WAAS CLI
to configure passwords and privilege levels for users on your WAAS devices, if possible. For
information about how to use the WAAS Central Manager GUI to centrally configure and
administer users on an single WAE or group of WAEs, which are registered with a WAAS
Central Manager, see the Cisco Wide Area Application Services Configuration Guide.
The username global configuration command allows you to change the password and privilege level for
existing user accounts. To change the password for the predefined superuser account on a per device
basis, use the password option of the username global configuration command:
waas-cm(config)# username admin password ?
0
Specifies an UNENCRYPTED password will follow
1
Specifies a HIDDEN password will follow
WORD The UNENCRYPTED (cleartext) user password
For example, change the predefined password for the superuser account to mysecret for the WAAS
Central Manager named waas-cm, as follows:
waas-cm# config
waas-cm#(config)# username admin password mysecret
waas-cm#(config)# exit

Chapter 3 CLI Commands
(config) username
User Authentication
User access is controlled at the authentication level. For every HTTP request, including every WAAS
CLI request, that arrives at the WAAS device, the authentication level has visibility into the supplied
username and password. Based on CLI-configured parameters, a decision is then made to either accept
or reject the request. This decision is made either by checking local authentication or by performing a
query against a remote authentication server. The authentication level is decoupled from the
authorization level, and there is no concept of role or domain at the authentication level.
When local CLI authentication is used, all configured users can be displayed by entering the show
running-config EXEC command.
User Authorization
Domains and roles are applied by the WAAS device at the authorization level. Requests must be accepted
by the authentication level before they are considered by the authorization level. The authorization level
regulates access to resources based on the specified role in WAAS Central Manager GUI and domain
configuration.
Regardless of the authentication mechanism, all user authorization configuration is visible in the GUI.

(config) wccp flow-redirect
To enable WCCP flow redirection on a WAE, use the wccp flow-redirect global configuration
command. To disable flow redirection, use the no form of this command.
wccp flow-redirect enable
Syntax Description
enable
Defaults
Enabled
Command Modes
global configuration
Device Modes
application-accelerator
Usage Guidelines
WCCP flow protection is a mechanism that ensures that no existing flows are broken when a new WAE
is brought online or removed from a service group. When transparent traffic interception or redirection
first begins, WCCP flow protection ensures that no existing HTTP flows are broken by allowing
preexisting, established HTTP flows to continue on. WCCP flow protection also ensures that when a new
WAE joins an existing WAE group, existing flows serviced by preexisting WAEs in the cluster continue
to receive those existing flows.
Enables flow redirection.
The mechanisms used by WCCP flow protection result in all of the benefits of maintaining per flow state
information in a centralized location but without the overhead, scaling issues, and redundancy or
resiliency issues (for example, asymmetrical traffic flows) associated with keeping per flow state
information in the switching layer.
Use the wccp flow-redirect global configuration command to implement WCCP flow protection. Flow
protection is designed to keep the TCP flow intact as well as to not overwhelm WAEs when they are first
started up or are reassigned new traffic. This feature also has a slow start mechanism whereby the WAEs
try to take a load appropriate for their capacity.
Note
When bypass is enabled, the client itself tries to reach the origin web server. You must disable all bypass
options to eliminate an unnecessary burden on the network.
WCCP works only with IPv4 networks.
Examples
The following example shows how to enable WCCP flow protection on a WAE:
WAE(config)# wccp flow-redirect enable

(config) wccp router-list
To configure a router list for WCCP Version 2, use the wccp router-list global configuration command.
To disable this function, use the no form of this command.
wccp router-list number ip-address
Syntax Description
number
Router list number (1–8).
ip-address
IP address of router to add to the list.
Defaults
Disabled
Command Modes
global configuration
Device Modes
application-accelerator
Usage Guidelines
As part of configuring a WCCP Version 2 service on a WAE, you must create a list of WCCP
Version 2-enabled routers that support the CIFS cache service for the WAE.
Each router list can contain up to eight routers. You can add up to 8 router lists and up to 32 IP addresses
per list.
Note
The ip wccp global configuration command must be used to enable WCCP on each router that is
included on the router list.
WCCP works only with IPv4 networks.
Examples
In the following example, router list number 7 is created, and it contains a single router (the WCCP
Version 2-enabled router with IP address 192.168.68.98):
WAE(config)# wccp router-list 7 192.168.68.98
The following example deletes the router list number 7 created in the previous example:
WAE(config)# no wccp router-list 7 192.168.68.98
The following example shows how to create a router list (router list 1) and then configure the WAE to
accept redirected TCP traffic from the WCCP Version 2-enabled router on router list 1:
WAE(config)# wccp router-list 1 10.10.10.2
WAE(config)# wccp tcp-promiscuous router-list 1

(config) wccp shutdown
To set the maximum time interval after which the WAE will perform a clean shutdown of WCCP, use the
wccp shutdown global configuration command. To disable the clean shutdown, use the no form of the
command.
wccp shutdown max-wait seconds
Syntax Description
max-wait
Sets the clean shutdown time interval.
seconds
Time in seconds (0–86400). The default is 120 seconds.
Defaults
The maximum time interval before a clean shutdown is 120 seconds by default.
Command Modes
global configuration
Device Modes
application-accelerator
Usage Guidelines
To prevent broken TCP connections, the WAE performs a clean shutdown of WCCP after a reload or
wccp version command is issued. The WAE does not reboot until either all connections have been
serviced or the configured max-wait interval has elapsed.
During a clean shutdown, the WAE continues to service the flows it is handling, but starts to bypass new
flows. When the number of flows goes down to zero, the WAE takes itself out of the cluster by having
its buckets reassigned to other WAEs by the lead WAE. TCP connections can still be broken if the WAE
crashes or is rebooted without WCCP being cleanly shut down. The clean shutdown can be aborted while
in progress.
You cannot shut down an individual WCCP service on a particular port on a WAE; you must shut down
WCCP on the WAE. After WCCP is shut down on the WAE, the WAE preserves its WCCP configuration
settings and services proxy-style requests (for example, HTTP requests that the FWAE receives directly
from a client browser).
Note
WCCP works only with IPv4 networks.

Usage Guidelines
Within a service group of WAEs, TCP connections are redirected to other WAEs as units are added or
removed. A WAE can be overloaded if it is reassigned new traffic too quickly or introduced abruptly into
a fat pipe.
Enables WCCP slow start.
WCCP slow start performs the following tasks to prevent a WAE from being overwhelmed when it comes
online or is reassigned new traffic:
•
TCP flow protection when WCCP 2 is enabled and a WAE is introduced into the service group
•
TCP flow protection when WCCP 2 is disabled and a WAE is leaving the service group
•
Load assignment to the WAE in slow increments rather than a full load at bootup
Slow start is applicable only in the following cases:
•
Initial bootup when there is no WAE yet present in the service group
•
When a new WAE is added to a service group that is not handling the full load; for example, when
there are some buckets that are being shed by the service group
In all other cases slow start is not necessary, and all the WAEs can be immediately assigned their share
of traffic.
Note
WCCP works only with IPv4 networks.

Usage Guidelines
WCCP provides the mechanism to transparently redirect client requests to a WAE for processing. To
configure basic WCCP, you must enable the WCCP service on the router and the Core WAE in the data
center and the router and Edge WAE in the branch office. It is not necessary to configure all of the
available WCCP features or services to get a WAE up and running.
This WCCP service requires that WCCP Version 2 is running on the router and the WAE.
The TCP promiscuous mode service is a WCCP service that intercepts all TCP traffic and redirects it to
the local WAE.
In order for the WAE to function as a promiscuous TCP device for TCP traffic that is transparently
redirected to it by the specified WCCP Version 2 routers, the WAE uses WCCP Version 2 services 61
and 62. The WCCP services 61 and 62 are represented by the canonical name of “tcp-promiscuous” on
the WAE, as shown in the following sample output of the WAAS CLI on an Edge WAE:
Edge-WAE1(config)# wccp ?
access-list
Configure an IP access-list for inbound WCCP encapsulated
traffic
flow-redirect

Note
Examples
WCCP works with IPv4 networks only.
The following example shows how to turn on the TCP promiscuous mode service and associate this
service with the router list by using the wccp tcp-promiscuous router-list-num command:
WAE # wccp tcp-promiscuous router-list-num 1
WCCP configuration for TCP Promiscuous service 61 succeeded.
WCCP configuration for TCP Promiscuous succeeded.
Please remember to configure WCCP service 61 and 62 on the corresponding router.

wccp version 2
Syntax Description
This command has no arguments or keywords.
Defaults
No default behavior or values
Command Modes
global configuration
Device Modes
application-accelerator
Usage Guidelines
You must configure a WAE to use WCCP Version 2 instead of WCCP Version 1 because WCCP
Version 1 only supports web traffic (port 80).
The WAE performs a clean shutdown after a reload or no wccp version 2 command is entered. A clean
shutdown prevents broken TCP connections.
The following sequence of events details the interaction between WAEs and routers that have been
configured to run WCCP Version 2:
1.
Each WAE is configured with a router list. (See the “(config) wccp router-list” command.)
2.
Each WAE announces its presence and a list of all routers with which it has established
communications. The routers reply with their view (list) of WAEs in the group.
Routers and WAEs become aware of one another and form a WCCP service group using a
management protocol. The WAEs also send periodic “Here I am” messages to the routers that allow
the routers to rediscover the WAEs. To properly depict the view, the protocol needs to include the
list of routers in the service group as part of its messages.
3.
Once the view is consistent across all the WAEs in the WAE cluster, one WAE is designated the lead.
When there is a group of WAEs, the one seen by all routers and the one that has the lowest IP address
becomes the lead WAE.
The role of this lead WAE is to determine how traffic should be allocated across the WAEs in the
WAE group. The lead WAE sets the policy that the WCCP-enabled routers must adhere to when
redirecting packets to the WAEs in this cluster. The assignment information is passed to the entire
service group from the designated WAE so that the routers in the service group can redirect the
packets properly and the WAEs in the service group can better manage their load.
Note
WCCP works only with IPv4 networks.

Usage Guidelines
The failover timeout command is used in inlineGroup interface scope. It sets the maximum time (in
seconds) for the inline interface to transition to a fail-to-wire mode of operation after a failure event
occurs (such as a power outage and kernel crash). For example, if the timeout is set to 3 seconds, traffic
is dropped for a maximum of 3 seconds after the WAE loses power or suffers a kernel crash. After this
time, all traffic received on either port of the group interface is sent out of the other port in the group.
The default timeout is 1 second.
Examples
The following example sets the failover time limit for the inline group 0 of the adapter that is installed
in slot 1 to 5 seconds and then removes that setting:
(config)# interface inlineGroup 1/0
(config-if)# failover timeout 5

Usage Guidelines
Use this EXEC command to configure an interface for full-duplex operation. Full duplex allows data to
travel in both directions at the same time through an interface or a cable. A half-duplex setting ensures
that data only travels in one direction at any given time. Although full duplex is faster, the interfaces
sometimes cannot operate effectively in this mode. If you encounter excessive collisions or network
errors, configure the interface for half duplex rather than full duplex.

(config-if) half-duplex
To configure an interface for half-duplex operation on a WAAS device, use the half-duplex interface
configuration command. To disable this function, use the no form of this command.
half-duplex
Syntax Description
This command has no arguments or keywords.
Defaults
No default behavior or values
Command Modes
interface configuration
Device Modes
application-accelerator
central-manager
Usage Guidelines
Use this interface configuration command to configure an interface for half-duplex operation. Full
duplex allows data to travel in both directions at the same time through an interface or a cable. A
half-duplex setting ensures that data only travels in one direction at any given time. Although full duplex
is faster, the interfaces sometimes cannot operate effectively in this mode. If you encounter excessive
collisions or network errors, configure the interface for half duplex rather than full duplex.
Examples
The following example configures half-duplex operation on the Gigabit Ethernet interface in
slot 1/port 0:
WAE# configure
WAE(config)# interface GigabitEthernet 1/0
WAE(config-if)# half-duplex
The following example disables half-duplex operation:
WAE(config-if)# no half-duplex

(config-if) inline
(config-if) inline
To enable inline interception for an inlineGroup interface, use the inline interface configuration
command. To disable inline interception, use the no form of this command.
inline [vlan {all | native | vlan_list}]
Syntax Description
vlan
(Optional) Modifies the VLAN list parameters.
all
Applies the command to all tagged and untagged packets.
native
Specifies untagged packets.
vlan_list
List of VLAN IDs to either allow or restrict on this interface. A comma (,)
is used to separate list entries. A hyphen (-) is used to specify a range of
VLAN IDs. The valid range is 0 to 4095.
Defaults
The default is enabled for all VLANs if you have a WAE inline network adapter installed.
Command Modes
interface configuration
Device Modes
application-accelerator
central-manager
Usage Guidelines
The inline command is used in inlineGroup interface scope. It enables or disables inline interception. If
the VLAN list is omitted, the command applies to all VLAN tagged or untagged packets.You can restrict
the inline feature to any specified set of VLANs.
The VLAN list can be “all” or a comma-separated list of VLAN IDs or ranges of VLAN IDs. The special
VLAN ID “native” can be included to specify untagged packets.
Note
Examples
When inline inspection is active, you cannot configure WCCP until you explicitly disable the
inline capability on all VLANs. Conversely, you cannot enable inline interception on any inline
groups until you disable WCCP.
The following example shows how to enable inline interception for all untagged and tagged packets with
any VLAN ID received on ports in inlineGroup 0 of the adapter that is installed in slot 1:
(config)# interface inlineGroup 1/0
(config-if)# inline
(config-if)# exit
The following example shows how to disable inline interception on the same ports for
802.1Q-encapsulated packets that have the VLAN ID 5 or any VLAN ID between 10 and 15, inclusive.
If the two VLANs are combined in the given order, inline interception is performed for all packets
received on ports in group 0 of slot 1, except those on VLANs 5, 10, 11, 12, 13, 14 and 15.

(config-if)# exit
The following example shows how to enable inline interception for traffic only on VLAN 395 on the
ports in group 1 in slot 2. Because the default behavior is to enable traffic on all VLANs, you must first
disable all VLANs, then enable just the set that you want.

Usage Guidelines
You can configure one or more interfaces to act as a backup interface (a standby interface) for another
interface on a WAAS device. This feature is called “standby interface support.” Standby groups, which
are logical groups of interfaces, are used to implement this feature. When an active network interface
fails (because of cable trouble, Layer 2 switch failure, high error count, or other failures) and that
interface is part of a standby group, a standby interface can become active and take the load off the failed
interface.
There must be at least two interfaces in a standby group. Interfaces that are part of a standby group are
called “member interfaces.” After you create a standby group, you define which interfaces should be
assigned to this logical group. As part of defining the member interfaces, you specify the priority of each
member interface in a standby group. The member interface with the highest assigned priority is the
active interface for that particular standby group. If the active interface fails, the operational member
interface with the next highest priority in the standby group comes up, and so forth. If all member
interfaces of a particular standby group are down and then one of the member interfaces comes up, the
WAAS software detects this situation and brings up the standby group on the member interface that just
came up.
The failure or failover of member interfaces within a standby group triggers alarms and traps (if alarms
and traps are enabled on the WAAS device). Alarms are sent out when failover occurs between member
interfaces in a standby group. Specifically, minor alarms are sent out when member interfaces fail, and
these alarms are cleared automatically when the interface failover has been successfully completed.
Major alarms are sent out if the standby group goes down (that is, no member interface in a standby
group can be brought up.)
Note
A physical interface can belong to more than one standby group. Consequently, a single interface can act
as a standby interface for more than one standby group.
To configure standby interfaces, interfaces are logically assigned to standby groups. The following rules
define the standby group relationships:
•
Each standby group is assigned a unique standby IP address, shared by all member interfaces of the
standby group. The IP address of the standby group is shared among the member interfaces;
however, only the active interface of the standby group uses this shared IP address at any one time.
This shared IP address is configured as an alias on the active interface.
•
Configure the duplex and speed settings of the member interfaces for better reliability.
•
If all the member interfaces of a standby group fail and then one recovers, the WAAS software brings
up the standby group on the operational member interface.
•
If a physical interface is a member of a port channel group, it cannot join a standby group. Likewise,
if a physical interface is a member of a standby group, it cannot join a port channel group.
•
A standby group comprises two or more interfaces.
•
The maximum number of standby groups on a WAAS device is four.

OL-11817-01
Chapter 3 CLI Commands
(config-if) standby
Note
Examples
Interface IP addresses and standby group IP addresses must be on different subnets to ensure reliable
operation. You can use dummy IP addresses in the private address space to serve as interface primary IP
addresses, and use the real WAAS device’s IP address to serve as the standby group IP address in a
different subnet to satisfy this requirement. When dummy IP addresses are used, these interface IP
addresses serve only as substitutes to bring up the interface. For example, the WAAS device’s interface
requires an IP address on an interface for initialization. Make sure to configure the interface default
gateway using the ip default-gateway global configuration command instead of the ip route command.
•
Each interface in a standby group is assigned a priority. The operational interface with the highest
priority in a standby group is the active interface. Only the active interface uses the group IP address.
•
The priority of an interface in a standby group can be changed at runtime. The member interface that
has the highest priority after this change becomes the new active interface (the default action is to
preempt the currently active interface if an interface with higher priority exists).
•
The maximum number of errors allowed on the active interface before the interface is shut down and
the standby is brought up is configured with the errors option, which is disabled by default.
Tip
If an interface belongs to more than one standby group, you can configure the interface with a different
priority in each standby group for better load-balancing. For example, interfaces Gigabit Ethernet 1/0
and Gigabit Ethernet 2/0 are both in standby group 1 and in standby group 2. If you configure Gigabit
Ethernet 1/0 with the highest priority in standby group 1 and configure Gigabit Ethernet 2/0 with the
highest priority in standby group 2, standby group 1 uses Gigabit Ethernet 1/0 as the active interface,
while standby group 2 uses Gigabit Ethernet 2/0 as the active interface. This configuration allows each
interface to back up the other one, if one of them fails.
Note
Unlike port channels, standby groups do not support IP ACLs at a group level. However, you can
configure a member interface of a standby group to support an IP ACL at the interface level. For
example, you can individually configure the two member interfaces of Standby Group 1 (the
Gigabit Ethernet slot 1/port 0 interface and the Gigabit Ethernet slot 2/port 0 interface) to support an IP
ACL named ACL1, but you cannot configure the Standby Group 1 to support ACL1.
The following example configures two Gigabit Ethernet interfaces to be part of the same standby group,
with interface 1/0 as the active interface:

The following example assigns a group IP address of 10.10.10.10 and a netmask of 255.0.0.0 to Standby
Group 1. You can configure a group IP address regardless of whether the standby group is shut down or
not.
WAE(config-if)# ip address 10.10.10.10 255.0.0.0
WAE(config-if)# errors 500
The following example shows how to add two Gigabit Ethernet interfaces to Standby Group 1 and then
assign each of these member interfaces a priority within the group:
a.
First a Gigabit Ethernet interface (slot 1/port 0) is added to Standby Group 1 and assigned a priority
of 150.
WAE(config)# interface gigabitEthernet 1/0
WAE(config-if)# standby 1 priority 150
b.
Next, a second Gigabit Ethernet interface (slot 2/port 0) is added to Standby Group 1 and assigned
a priority of 100 (the default value).
WAE(config)# interface gigabitEthernet 2/0
WAE(config-if)# standby 1
WAE(config-if)# exit
WAE(config)#
Because GigabitEthernet 0/0 is assigned the highest priority (a priority number of 150) of all the member
interfaces in the group, it is chosen as the active interface for the group if it can be brought up.
The following example removes the GigabitEthernet slot 1/port 0 interface from Standby Group 1 using
the no form of the standby command:
WAE(config)# interface gigabitEthernet 1/0
WAE(config-if)# no standby 1
WAE(config-if)# exit
WAE(config)#
The following example shows how to shut down Standby Group 1. When a standby group is shut down,
all of the alarms previously raised by this standby group are cleared:
WAE(config)# interface standby 1
WAE(config-if)# exit
WAE(config)# exit
The following example shows how to tear down Standby Group 1:
WAE(config)# interface standby 1
WAE(config-if)# no ip address 10.10.10.10 255.0.0.0
Please remove member interface(s) from this standby group first.

Standard ACL Configuration Mode Commands
To create and modify standard access lists on a WAAS device for controlling access to interfaces or
applications, use the ip access-list standard global configuration command. To disable a standard
access list, use the no form of the command.
ip access-list standard {acl-name | acl-num}

standard
Enables standard ACL configuration mode. The CLI enters the standard
ACL configuration mode in which all subsequent commands apply to the
current standard access list. The (config-std-nacl) prompt appears:
WAE(config-std-nacl)#
acl-name
Access list to which all commands entered from ACL configuration mode
apply, using an alphanumeric string of up to 30 characters, beginning with
a letter.
acl-num
Access list to which all commands entered from access list configuration
mode apply, using a numeric identifier. For standard access lists, the valid
range is 1 to 99.
Defaults
An access list drops all packets unless you configure at least one permit entry.
Command Modes
Global configuration
Device Modes
application-accelerator
central-manager
Usage Guidelines
Note
Use access lists to control access to specific applications or interfaces on a WAAS device. An access
control list consists of one or more condition entries that specify the kind of packets that the WAAS
device will drop or accept for further processing. The WAAS device applies each entry in the order in
which it occurs in the access list, which by default is the order in which you configured the entry.
IP ACLs that are defined on a router take precedence over the IP ACLs that are defined on the WAE. IP
ACLs that are defined on a WAE take precedence over the WAAS application definition policies that are
defined on the WAE.
Within ACL configuration mode, you can use the editing commands (list, delete, and move) to display
the current condition entries, to delete a specific entry, or to change the order in which the entries will
be evaluated. To return to global configuration mode, enter exit at the ACL configuration mode prompt.
Cisco Wide Area Application Services Command Reference
3-438
OL-11817-01
Chapter 3 CLI Commands
To create an entry, use a deny or permit keyword and specify the type of packets that you want the
WAAS device to drop or to accept for further processing. By default, an access list denies everything
because the list is terminated by an implicit deny any entry. Therefore, you must include at least one
permit entry to create a valid access list.
After creating an access list, you can include the access list in an access group using the access-group
command, which determines how the access list is applied. You can also apply the access list to a specific
application using the appropriate command. A reference to an access list that does not exist is the
equivalent of a permit any condition statement.
To create a standard access list, enter the ip access-list standard global configuration command.
Identify the new or existing access list with a name up to 30 characters long beginning with a letter, or
with a number. If you use a number to identify a standard access list, it must be between 1 and 99.
Note
You must use a standard access list for providing access to the SNMP server or to the TFTP
gateway/server. However, you can use either a standard access list or an extended access list for
providing access to the WCCP application.
You typically use a standard access list to allow connections from a host with a specific IP address or
from hosts on a specific network. To allow connections from a specific host, use the permit host
source-ip option and replace source-ip with the IP address of the specific host.
To allow connections from a specific network, use the permit host source-ip wildcard option. Replace
source-ip with a network ID or the IP address of any host on the network that you want to specify.
Replace wildcard with the dotted decimal notation for a mask that is the reverse of a subnet mask, where
a 0 indicates a position that must be matched and a 1 indicates a position that does not matter. For
instance, the wildcard 0.0.0.255 causes the last eight bits in the source IP address to be ignored.
Therefore, the permit 192.168.1.0 0.0.0.255 entry allows access from any host on the 192.168.1.0
network.
After you identify the standard access list, the CLI enters the standard ACL configuration mode and all
subsequent commands apply to the specified access list.
WAE(config)# ip access-list standard teststdacl
WAE(config-std-nacl)# exit
Examples
The following example creates a standard access list on the WAAS device that permits any packets from
source IP address 192.168.1.0 for further processing:
WAE(config)# ip access-list standard teststdacl
WAE(config-std-nacl)# permit 192.168.1.0 any
WAE(config-std-nacl)# exit
The following commands activate the access list for an interface:
WAE(config)# interface gigabitethernet 1/0
WAE(config-if)# ip access-group teststdacl in
WAE(config-if)# exit
The following example shows how this configuration appears when you enter the show

format (for example, 0.0.0.0).
wildcard
(Optional) Portions of the preceding IP address to match, expressed using
4-digit, dotted-decimal notation. Bits to match are identified by a digital
value of 0; bits to ignore are identified by a 1.
Note
For standard IP ACLs, the wildcard parameter of the ip access-list
command is always optional. If the host keyword is specified for a
standard IP ACL, then the wildcard parameter is not allowed.

Usage Guidelines
To create an entry, use a deny or permit keyword and specify the type of packets that you want the
WAAS device to drop or to accept for further processing. By default, an access list denies everything
because the list is terminated by an implicit deny any entry. Therefore, you must include at least one
permit entry to create a valid access list.
You typically use a standard access list to allow connections from a host with a specific IP address or
from hosts on a specific network. To allow connections from a specific host, use the permit host
source-ip option and replace source-ip with the IP address of the specific host.

Extended ACL Configuration Mode Commands
To create and modify extended access lists on a WAAS device for controlling access to interfaces or
applications, use the ip access-list extended global configuration command. To disable an extended
access list, use the no form of the command.
ip access-list extended {acl-name | acl-num}
Syntax Description
extended
Enables extended ACL configuration mode. The CLI enters the extended
ACL configuration mode in which all subsequent commands apply to the
current extended access list. The (config-ext-nacl) prompt appears:
WAE(config-ext-nacl)#
acl-name
Access list to which all commands entered from ACL configuration mode
apply, using an alphanumeric string of up to 30 characters, beginning with
a letter.
acl-num
Access list to which all commands entered from access list configuration
mode apply, using a numeric identifier. For extended access lists, the valid
range is 100 to 199.
Defaults
An access list drops all packets unless you configure at least one permit entry.
Command Modes
Global configuration
Device Modes
application-accelerator
central-manager
Usage Guidelines
Use access lists to control access to specific applications or interfaces on a WAAS device. An access
control list consists of one or more condition entries that specify the kind of packets that the WAAS
device will drop or accept for further processing. The WAAS device applies each entry in the order in
which it occurs in the access list, which by default is the order in which you configured the entry.
The following list contains examples of how ACLs can be used in environments that use WAAS devices:
•
A WAAS device resides on the customer premises and is managed by a service provider, and the
service provider wants to secure the device for its management only.
•
A WAAS device is deployed anywhere within the enterprise. As with routers and switches, the
administrator wants to limit Telnet, SSH, and WAAS GUI access to the IT source subnets.
Cisco Wide Area Application Services Command Reference
OL-11817-01
3-449
Chapter 3 CLI Commands
Note
•
An application layer proxy firewall with a hardened outside interface has no ports exposed.
(Hardened means that the interface carefully restricts which ports are available for access, primarily
for security reasons. With an outside interface, many types of security attacks are possible.) The
WAE's outside address is Internet global, and its inside address is private. The inside interface has
an ACL to limit Telnet, SSH, and WAAS GUI access to the device.
•
A WAAS device using WCCP is positioned between a firewall and an Internet router or a subnet off
the Internet router. Both the WAAS device and the router must have ACLs.
ACLs that are defined on a router take precedence over the ACLs that are defined on the WAE. ACLs
that are defined on a WAE take precedence over the WAAS application definition policies that are
defined on the WAE.
Within ACL configuration mode, you can use the editing commands (list, delete, and move) to display
the current condition entries, to delete a specific entry, or to change the order in which the entries will
be evaluated. To return to global configuration mode, enter exit at the ACL configuration mode prompt.
To create an entry, use a deny or permit keyword and specify the type of packets that you want the
WAAS device to drop or to accept for further processing. By default, an access list denies everything
because the list is terminated by an implicit deny any entry. Therefore, you must include at least one
permit entry to create a valid access list.
After creating an access list, you can include the access list in an access group using the access-group
command, which determines how the access list is applied. You can also apply the access list to a specific
application using the appropriate command. A reference to an access list that does not exist is the
equivalent of a permit any condition statement.
To create an extended access list, enter the ip access-list extended global configuration command.
Identify the new or existing access list with a name up to 30 characters long beginning with a letter, or
with a number. If you use a number to identify an extended access list, it must be from 100 to 199
Note
You must use a standard access list for providing access to the SNMP server or to the TFTP
gateway/server. However, you can use either a standard access list or an extended access list for
providing access to the WCCP application.
To allow connections from a specific host, use the permit host source-ip option and replace source-ip
with the IP address of the specific host.
To allow connections from a specific network, use the permit host source-ip wildcard option. Replace
source-ip with a network ID or the IP address of any host on the network that you want to specify.
Replace wildcard with the dotted decimal notation for a mask that is the reverse of a subnet mask, where
a 0 indicates a position that must be matched and a 1 indicates a position that does not matter. For
instance, the wildcard 0.0.0.255 causes the last eight bits in the source IP address to be ignored.
Therefore, the permit 192.168.1.0 0.0.0.255 entry allows access from any host on the 192.168.1.0
network.
After you identify the extended access list, the CLI enters the extended ACL configuration mode and all
subsequent commands apply to the specified access list.

OL-11817-01
Chapter 3 CLI Commands
(config-ext-nacl) deny
To allow connections from a specific network, use the permit host source-ip wildcard option. Replace
source-ip with a network ID or the IP address of any host on the network that you want to specify.
Replace wildcard with the dotted decimal notation for a mask that is the reverse of a subnet mask, where
a 0 indicates a position that must be matched and a 1 indicates a position that does not matter. For
instance, the wildcard 0.0.0.255 causes the last eight bits in the source IP address to be ignored.
Therefore, the permit 192.168.1.0 0.0.0.255 entry allows access from any host on the 192.168.1.0
network.
For extended IP ACLs, the wildcard parameter is required if the host keyword is not specified.
Use an extended access list to control connections based on the destination IP address or based on the
protocol type. You can combine these conditions with information about the source IP address to create
more restrictive condition.

The following example shows how to create an access list on the WAAS device. You create this access
list to allow the WAAS device to accept all web traffic that is redirected to it, but limits host
administrative access using SSH:
WAE(config)# ip access-list extended testextacl
WAE(config-ext-nacl)# permit tcp any any eq www
WAE(config-ext-nacl)# deny tcp host 10.1.1.5 any eq ssh
WAE(config-ext-nacl)# exit
The following example shows how to activate the access list for an interface:
WAE(config)# interface gigabitethernet 1/0
WAE(config-if)# ip access-group extended testextacl in
WAE(config-if)# exit

Chapter 3 CLI Commands
(config-ext-nacl) permit
(config-ext-nacl) permit
To add a line to an extended access-list that specifies the type of packets that you want the WAAS device
to accept for further processing, use the permit command. To add a condition to the extended ACL, note
that the options depend on the chosen protocol.
For IP, use the following syntax to add a condition:
[insert line-num] permit {gre | icmp | tcp | udp | ip | proto-num} {source-ip [wildcard] | host
source-ip | any} {dest-ip [wildcard] | host dest-ip | any}
no permit {gre | icmp | tcp | udp | ip | proto-num} {source-ip [wildcard] | host source-ip | any}
{dest-ip [wildcard] | host dest-ip | any}
For TCP, use the following syntax to add a condition:
[insert line-num] permit tcp {source-ip [wildcard] | host source-ip | any} [operator port [port]]
{dest-ip [wildcard] | host dest-ip | any} [operator port [port]] [established]
no permit tcp {source-ip [wildcard] | host source-ip | any} [operator port [port]] {dest-ip
[wildcard] | host dest-ip | any} [operator port [port]] [established]
For UDP, use the following syntax to add a condition:
[insert line-num] permit udp {source-ip [wildcard] | host source-ip | any} [operator port [port]]
{dest-ip [wildcard] | host dest-ip | any} [operator port [port]]
no permit udp {source-ip [wildcard] | host source-ip | any} [operator port [port]] {dest-ip
[wildcard] | host dest-ip | any} [operator port [port]]
For ICMP, use the following syntax to add a condition:
[insert line-num] permit icmp {source-ip [wildcard] | host source-ip | any} {dest-ip [wildcard] |
host dest-ip | any} [icmp-type [code] | icmp-msg]
no permit icmp {source-ip [wildcard] | host source-ip | any} {dest-ip [wildcard] | host dest-ip |
any} [icmp-type [code] | icmp-msg]
Syntax Description
insert
(Optional) Inserts the conditions following the specified line number into
the access list.
line-num
Identifies the entry at a specific line number in the access list.
gre
Matches packets using the Generic Routing Encapsulation protocol.
icmp
Matches ICMP packets.
tcp
Matches packets using the TCP protocol.
udp
Matches packets using the UDP protocol.
ip
Matches all IP packets.
proto-num
(Optional) IP protocol number.
source-ip
Source IP address. The number of the network or host from which the
packet is being sent, specified as a 32-bit quantity in 4-part dotted-decimal
format (for example, 0.0.0.0).
Cisco Wide Area Application Services Command Reference
OL-11817-01
3-461
Chapter 3 CLI Commands
(config-ext-nacl) permit
wildcard
(Optional) Portions of the preceding IP address to match, expressed using
4-digit, dotted-decimal notation. Bits to match are identified by a digital
value of 0; bits to ignore are identified by a 1.
Note
For extended IP ACLs, the wildcard parameter of the ip access-list
command is always optional. If the host keyword is specified for a
extended IP ACL, then the wildcard parameter is not allowed.
host
Matches the following IP address.
any
Matches any IP address.
dest-ip
Destination IP address. The number of the network or host to which the
packet is being sent, specified as a 32-bit quantity in 4-part dotted decimal
format (for example, 0.0.0.0).
operator
(Optional) Operator to use with specified ports, where lt = less than, gt =
greater than, eq = equal to, neq = not equal to, and range = an inclusive
range.
port
(Optional) Port, using a number (0–65535) or a keyword; 2 port numbers
are required with range. See the Usage Guidelines section for a listing of
the UDP and TCP keywords.
established
(Optional) Matches TCP packets with the acknowledgment or reset bits set.
icmp-type
(Optional) Match with ICMP message type (0–255).
code
(Optional) Used with icmp-type to further match by ICMP code type
(0–255).
icmp-msg
(Optional) Match combination of ICMP message type and code types, as
expressed by the keywords shown in the Usage Guidelines section.
Defaults
An access list drops all packets unless you configure at least one permit entry.
Command Modes
Extended ACL configuration mode
Device Modes
application-accelerator
central-manager
Usage Guidelines
To create an entry, use a deny or permit keyword and specify the type of packets that you want the
WAAS device to drop or to accept for further processing. By default, an access list denies everything
because the list is terminated by an implicit deny any entry. Therefore, you must include at least one
permit entry to create a valid access list.
To allow connections from a specific host, use the permit host source-ip option and replace source-ip
with the IP address of the specific host.
To allow connections from a specific network, use the permit host source-ip wildcard option. Replace
source-ip with a network ID or the IP address of any host on the network that you want to specify.
Replace wildcard with the dotted decimal notation for a mask that is the reverse of a subnet mask, where
a 0 indicates a position that must be matched and a 1 indicates a position that does not matter. For
Cisco Wide Area Application Services Command Reference

OL-11817-01
Chapter 3 CLI Commands
(config-ext-nacl) permit
instance, the wildcard 0.0.0.255 causes the last eight bits in the source IP address to be ignored.
Therefore, the permit 192.168.1.0 0.0.0.255 entry allows access from any host on the 192.168.1.0
network.
For extended IP ACLs, the wildcard parameter is required if the host keyword is not specified.
Use an extended access list to control connections based on the destination IP address or based on the
protocol type. You can combine these conditions with information about the source IP address to create
more restrictive condition.
