The Command Line Interface
Your
GbE Switch Module (GbESM)
is ready to perform basic switching functions right out of the box. Some of the more advanced features, however, require some administrative configuration before they can be used effectively.
The extensive Alteon OS switching software included in your switch provides a variety of options for accessing and configuring the switch:
A built-in, text-based command line interface and menu system for access via a Telnet session or serial-port connection
SNMP support for access through network management software such as IBM Director or
HP OpenView
Alteon OS Browser-Based Interface (BBI)
The command line interface is the most direct method for collecting switch information and performing switch configuration. Using a basic terminal, you are presented with a hierarchy of menus that enable you to view information and statistics about the switch, and to perform any necessary configuration.
This chapter explains how to access the Command Line Interface (CLI) for the switch.
BMD00029, April 2008 19
Alteon OS Command Reference
Connecting to the Switch
You can access the command line interface in any one of the following ways:
Using a Telnet via the management module
Using a Telnet connection over the network
Using a SSH connection to securely log into another computer over a network
Using a serial connection using the serial port on the GbESM
Management Module Setup
The BladeCenter GbE Switch Module is an integral subsystem within the overall BladeCenter system. The BladeCenter chassis includes a management module (MM) as the central element for overall chassis management and control.
You can use the 100 Mbps Ethernet port on the management module to configure and manage the GbE Switch Module. The GbE Switch Module communicates with the management module through its internal port 15 (MGT1) and port 16 (MGT2), which you can access through the
Ethernet port on the management module. The factory default settings will permit only management and control access to the switch module through the Ethernet port on the management module, or the built-in serial port. You can use the six external 10/100/1000 Mbps Ethernet ports on the switch module for management and control of the switch by selecting this mode as an option through the management module configuration utility program (see the applicable
BladeCenter Installation and User’s Guide publications for more information).
Factory-Default vs. MM assigned IP Addresses
Each GbE Switch Module must be assigned its own Internet Protocol address, which is used for communication with an SNMP network manager or other transmission control protocol/
Internet Protocol (TCP/IP) applications (for example, BootP or TFTP). The factory-default IP address is 10.90.90.9x, where x corresponds to the number of the bay into which the GbE
20

Switch Module is installed. For additional information, see the Installation Guide). The management module assigns an IP address of 192.168.70.1xx, where xx corresponds to the number of the bay into which each GbE Switch Module is installed, as shown in the following table:
Table 1-1 GbESM IP addresses, based on switch-module bay numbers

OTE
– Switch Modules installed in Bay 1 and Bay 2 connect to server NICs 1 and 2, respectively. However, Windows operating systems show that Switch Modules installed in Bay 3 and
Bay 4 connect to server NICs 4 and 3, respectively.
Default Gateway
The default Gateway IP address determines where packets with a destination address outside the current subnet should be sent. Usually, the default Gateway is a router or host acting as an
IP gateway to handle connections to other subnets of other TCP/IP networks. If you want to access the GbE Switch Module from outside your local network, use the management module to assign a default Gateway address to the GbE Switch Module. Choose I/O Module Tasks >
Configuration from the navigation pane on the left, and enter the default Gateway IP address
(for example, 192.168.70.125). Click Save.
Configuring management module for switch access
Complete the following initial configuration steps:
1.
Connect the Ethernet port of the management module to a 10/100 Mbps network (with access to a management station) or directly to a management station.
2.
Access and log on to the management module, as described in the BladeCenter Manage-
ment Module User’s Guide. The management module provides the appropriate IP addresses for network access (see the applicable BladeCenter Installation and User’s
Guide publications for more information).
3.
Select Configuration on the I/O Module Tasks menu on the left side of the BladeCenter
Management Module window. See
BMD00029, April 2008 Chapter 1: The Command Line Interface
21
Alteon OS Command Reference
Figure 1-1 Switch management on the BladeCenter management module
4.
You can use the default IP addresses provided by the management module, or you can assign a new IP address to the switch module through the management module. You can assign this IP address through one of the following methods:
Manually through the BladeCenter management module
Automatically through the IBM Director Configuration Wizard (available in
Director release 4.21)
N
OTE
– If you change the IP address of the GbE Switch Module, make sure that the switch module and the management module both reside on the same subnet.
22
Chapter 1: The Command Line Interface BMD00029, April 2008
Alteon OS Command Reference
5.
Enable the following features in the management module:
External Ports (I/O Module Tasks > Admin/Power/Restart > Advance Setup)
External management over all ports (Configuration > Advanced Configuration)
This setting is required if you want to access the management network through the external ports on the GbE Switch Module.
The default value is Disabled for both features. If these features are not already enabled, change the value to Enabled, then Save.
N
OTE
– In Advanced Configuration > Advanced Setup, enable “Preserve new IP configuration on all switch resets,” to retain the switch’s IP interface when you restore factory defaults.
This setting preserves the management port’s IP address in the management module’s memory, so you maintain connectivity to the management module after a reset.
You can now start a Telnet session, Browser-Based Interface (Web) session, a Secure Shell session, or a secure HTTPS session to the GbE Switch Module.
Connecting to the Switch via Telnet
Use the management module to access the GbE Switch Module through Telnet. Choose
I/O Module Tasks > Configuration from the navigation pane on the left. Select a bay number and click Advanced Configuration > Start Telnet/Web Session > Start Telnet Session. A
Telnet window opens a connection to the Switch Module (requires Java 1.4 Plug-in).
Once that you have configured the GbE Switch Module with an IP address and gateway, you can access the switch from any workstation connected to the management network. Telnet access provides the same options for user and administrator access as those available through the management module, minus certain Telnet and management commands.
To establish a Telnet connection with the switch, run the Telnet program on your workstation and issue the Telnet command, followed by the switch IP address:
telnet
<switch IP address>
Running Telnet
Once the IP parameters on the
GbE Switch Module
are configured, you can access the CLI using a Telnet connection. From the management module, you can establish a Telnet connection with the switch.
You will then be prompted to enter a password as explained on
BMD00029, April 2008 Chapter 1: The Command Line Interface
23
Alteon OS Command Reference
Establishing an SSH Connection
Although a remote network administrator can manage the configuration of a
GbE Switch Module via Telnet, this method does not provide a secure connection. The SSH (Secure Shell) protocol enables you to securely log into another computer over a network to execute commands remotely. As a secure alternative to using Telnet to manage switch configuration, SSH ensures that all data sent over the network is encrypted and secure.
The switch can do only one session of key/cipher generation at a time. Thus, a SSH/SCP client will not be able to login if the switch is doing key generation at that time or if another client has just logged in before this client. Similarly, the system will fail to do the key generation if a
SSH/SCP client is logging in at that time.
The supported SSH encryption and authentication methods are listed below.
Server Host Authentication: Client RSA-authenticates the switch in the beginning of every connection.
Key Exchange: RSA
Encryption: 3DES-CBC, DES
User Authentication: Local password authentication, Radius
The following SSH clients have been tested:
SSH 1.2.23 and SSH 1.2.27 for Linux (freeware)
SecureCRT 3.0.2 and SecureCRT 3.0.3 (Van Dyke Technologies, Inc.)
F-Secure SSH 1.1 for Windows (Data Fellows)
N
OTE
– The Alteon OS implementation of SSH is based on SSH version 1.5 and supports SSH-
1.5-1.X.XX. SSH clients of other versions (especially Version 2) are not supported.
24
Chapter 1: The Command Line Interface BMD00029, April 2008
Alteon OS Command Reference
Running SSH
Once the IP parameters are configured and the SSH service is turned on the
GbE Switch Module
, you can access the command line interface using an SSH connection. The default setting for
SSH access is disabled.
To establish an SSH connection with the switch, run the SSH program on your workstation by issuing the SSH command, followed by the switch IP address:
>> # ssh
<switch IP address>
or, if SecurID authentication is required, use the following command:
>> # ssh -1 ace
<switch IP address>
You will then be prompted to enter your user name and password.
BMD00029, April 2008 Chapter 1: The Command Line Interface
25
Alteon OS Command Reference
Accessing the Switch
To enable better switch management and user accountability, three levels or classes of user access have been implemented on the
GbE Switch Module
. Levels of access to CLI, Web management functions, and screens increase as needed to perform various switch management tasks. Conceptually, access classes are defined as follows:
User interaction with the switch is completely passive—nothing can be changed on the
GbE Switch Module
. Users may display information that has no security or privacy implications, such as switch statistics and current operational state information.
Operators can only effect temporary changes on the
GbE Switch Module
. These changes will be lost when the switch is rebooted/reset. Operators have access to the switch management features used for daily switch operations. Because any changes an operator makes are undone by a reset of the switch, operators cannot severely impact switch operation.
Administrators are the only ones that may make permanent changes to the switch configuration—changes that are persistent across a reboot/reset of the switch. Administrators can access switch functions to configure and troubleshoot problems on the
GbE Switch Module
.
Because administrators can also make temporary (operator-level) changes as well, they must be aware of the interactions between temporary and permanent changes.
Access to switch functions is controlled through the use of unique surnames and passwords.
Once you are connected to the switch via local Telnet, remote Telnet, or SSH, you are prompted to enter a password. The default user names/password for each access level are listed in the following table.

Setup Versus CLI
Once the administrator password is verified, you are given complete access to the switch. If the switch is still set to its factory default configuration, the system will ask whether you wish to run Setup (see
Chapter 2, “First-Time Configuration ”), a utility designed to help you through
the first-time configuration process. If the switch has already been configured, the Main Menu of the CLI is displayed instead.

First-Time Configuration
To help with the initial process of configuring your switch, the Alteon OS software includes a
Setup utility. The Setup utility prompts you step-by-step to enter all the necessary information for basic configuration of the switch. This chapter describes how to use the Setup utility and how to change system passwords. Before you run Setup, you must first connect to the switch
(see
Chapter 1, “Connecting to the Switch ”).
BMD00029, April 2008 31
Alteon OS Command Reference
Using the Setup Utility
Whenever you log in as the system administrator under the factory default configuration, you are asked whether you wish to run the Setup utility. Setup can also be activated manually from the command line interface any time after login.
Information Needed For Setup
Setup requests the following information:
Basic system information
Date & time
Whether to use Spanning Tree Group or not
Optional configuration for each port
Speed, duplex, flow control, and negotiation mode (as appropriate)
Whether to use VLAN tagging or not (as appropriate)
Optional configuration for each VLAN
Name of VLAN
Which ports are included in the VLAN
Optional configuration of IP parameters
IP address, subnet mask, and VLAN for each IP interface
IP addresses for default gateway

Repeat the steps in this section until all default gateways have been configured. When all default gateways have been configured, press <Enter> without specifying any number.
IP Routing
When IP interfaces are configured for the various subnets attached to your switch, IP routing between them can be performed entirely within the switch. This eliminates the need to send inter-subnet communication to an external router device. Routing on more complex networks, where subnets may not have a direct presence on the
GbE Switch Module
, can be accomplished through configuring static routes or by letting the switch learn routes dynamically.
This part of the Setup program prompts you to configure the various routing parameters.

Menu Basics
The GbE Switch Module’s Command Line Interface (CLI) is used for viewing switch information and statistics. In addition, the administrator can use the CLI for performing all levels of switch configuration.
To make the CLI easy to use, the various commands have been logically grouped into a series of menus and sub-menus. Each menu displays a list of commands and/or sub-menus that are available, along with a summary of what each command will do. Below each menu is a prompt where you can enter any command appropriate to the current menu.
This chapter describes the Main Menu commands, and provides a list of commands and shortcuts that are commonly available from all the menus within the CLI.

SNMPv3 Access Table Information
The access control sub system provides authorization services.
The vacmAccessTable maps a group name, security information, a context, and a message type, which could be the read or write type of operation or notification into a MIB view.
The View-based Access Control Model defines a set of services that an application can use for checking access rights of a group. This group's access rights are determined by a read-view, a write-view and a notify-view. The read-view represents the set of object instances authorized for the group while reading the objects. The write-view represents the set of object instances authorized for the group when writing objects. The notify-view represents the set of object instances authorized for the group when sending a notification.

When in the trunking (TRK) state, the port field represents the trunk group number. If the state for the port is listed as unknown (UNK), the MAC address has not yet been learned by the switch, but has only been seen as a destination address. When an address is in the unknown state, no outbound port is indicated, although ports which reference the address as a destination will be listed under “Reference ports.”
If the state for the port is listed as an interface (IF), the MAC address is for a standard VRRP virtual router.

The switch software uses the IEEE 802.1D Spanning Tree Protocol (STP). In addition to seeing if STG is enabled or disabled, you can view the following STG bridge information:
Priority
Hello interval
Maximum age value
Forwarding delay
Aging time
You can also see the following port-specific STG information:

FwdDel
Aging priority
(port)
Description
The bridge priority parameter controls which bridge on the network will become the STG root bridge.
The hello time parameter specifies, in seconds, how often the root bridge transmits a configuration bridge protocol data unit (BPDU). Any bridge that is not the root bridge uses the root bridge hello value.
The maximum age parameter specifies, in seconds, the maximum time the bridge waits without receiving a configuration bridge protocol data unit before it reconfigure the STG network.
The forward delay parameter specifies, in seconds, the amount of time that a bridge port has to wait before it changes from learning state to forwarding state.
The aging time parameter specifies, in seconds, the amount of time the bridge waits without receiving a packet from a station before removing the station from the Forwarding Database.
The port priority parameter helps determine which bridge port becomes the designated port. In a network topology that has multiple bridge ports connected to a single segment, the port with the lowest port priority becomes the designated port for the segment.

/info/l3/vrrp
VRRP Information
Virtual Router Redundancy Protocol (VRRP) support on
GbE Switch Module
provides redundancy between routers in a LAN. This is accomplished by configuring the same virtual router IP address and ID number on each participating VRRP-capable routing device. One of the virtual routers is then elected as the master, based on a number of priority criteria, and assumes control of the shared virtual router IP address. If the master fails, one of the backup virtual routers will assume routing authority and take control of the virtual router IP address.
VRRP information:
1: vrid 2, 205.178.18.210, if 1, renter, prio 100, master, server
2: vrid 1, 205.178.18.202, if 1, renter, prio 100, backup
3: vrid 3, 205.178.18.204, if 1, renter, prio 100, master, proxy
When virtual routers are configured, you can view the status of each virtual router using this command. VRRP information includes:
Virtual router number
Virtual router ID and IP address
Interface number
Ownership status
owner
identifies the preferred master virtual router. A virtual router is the owner when the IP address of the virtual router and its IP interface are the same.
renter
identifies virtual routers which are not owned by this device.
Priority value. During the election process, the virtual router with the highest priority becomes master.
Activity status
master backup
identifies the elected master virtual router.
identifies that the virtual router is in backup mode.
init
identifies that the virtual router is waiting for a startup event.
For example, once it receives a startup event, it transitions to master if its priority is 255, (the IP address owner), or transitions to backup if it is not the IP address owner.
Server status. The server state identifies virtual routers.
Proxy status. The proxy state identifies virtual proxy routers, where the virtual router shares the same IP address as a proxy IP address. The use of virtual proxy routers enables redundant switches to share the same IP address, minimizing the number of unique IP addresses that must be configured.

Collisions
The number of times that a collision is detected on a particular interface later than 512 bit-times into the transmission of a packet.
Five hundred and twelve bit-times corresponds to 51.2 microseconds on a
10 Mbit/s system. A (late) collision included in a count represented by an instance of this object is also considered as a (generic) collision for purposes of other collision-related statistics.
A count of frames for which transmission on a particular interface fails due to excessive collisions.
dot3StatsInternal-
MacTransmitErrors dot3StatsFrameToo-
Longs
A count of frames for which transmission on a particular interface fails due to an internal MAC sub layer transmit error. A frame is only counted by an instance of this object if it is not counted by the corresponding instance of either the dot3StatsLateCollisions object, the dot3StatsExcessiveCollisions
object, or the dot3Stats-

The total number of input datagrams received from interfaces, including those received in error.
The number of input datagrams discarded due to errors in their IP headers, including bad checksums, version number mismatch, other format errors, time-to-live exceeded, errors discovered in processing their IP options, and so forth.
The number of input datagrams discarded because the IP address in their
IP header's destination field was not a valid address to be received at this entity (the switch). This count includes invalid addresses (for example,
0.0.0.0) and addresses of unsupported Classes (for example, Class E). For entities which are not IP Gateways and therefore do not forward datagrams, this counter includes datagrams discarded because the destination address was not a local address.
The number of input datagrams for which this entity (the switch) was not their final IP destination, as a result of which an attempt was made to find a route to forward them to that final destination. In entities which do not act as IP Gateways, this counter will include only those packets, which were Source-Routed via this entity (the switch), and the Source- Route option processing was successful.
The number of locally addressed datagrams received successfully but discarded because of an unknown or unsupported protocol.
The number of input IP datagrams for which no problems were encountered to prevent their continued processing, but which were discarded (for example, for lack of buffer space). Note that this counter does not include any datagrams discarded while awaiting re-assembly.

Description
The total number of input datagrams successfully delivered to IP userprotocols (including ICMP).
The total number of IP datagrams which local IP user-protocols (including ICMP) supplied to IP in requests for transmission. Note that this counter does not include any datagrams counted in ipForwDatagrams
.
The number of output IP datagrams for which no problem was encountered to prevent their transmission to their destination, but which were discarded (for example, for lack of buffer space). Note that this counter would include datagrams counted in ipForwDatagrams if any such packets met this (discretionary) discard criterion.
The number of IP datagrams discarded because no route could be found to transmit them to their destination. Note that this counter includes any packets counted in ipForwDatagrams, which meet this no-route criterion. Note that this includes any datagrams which a host cannot route because all of its default gateways are down.
The number of IP fragments received which needed to be reassembled at this entity (the switch).
The number of IP datagrams successfully re- assembled.
The number of failures detected by the IP re- assembly algorithm (for whatever reason: timed out, errors, and so forth). Note that this is not necessarily a count of discarded IP fragments since some algorithms (notably the algorithm in RFC 815) can lose track of the number of fragments by combining them as they are received.
The number of IP datagrams that have been successfully fragmented at this entity (the switch).
The number of IP datagrams that have been discarded because they needed to be fragmented at this entity (the switch) but could not be, for example, because their Don't Fragment flag was set.
The number of IP datagram fragments that have been generated as a result of fragmentation at this entity (the switch).
The number of routing entries, which were chosen to be discarded even though they are valid. One possible reason for discarding such an entry could be to free-up buffer space for other routing entries.
The default value inserted into the Time-To-Live (TTL) field of the
IP header of datagrams originated at this entity (the switch), whenever a
TTL value is not supplied by the transport layer protocol.

VRRP Statistics
Virtual Router Redundancy Protocol (VRRP) support on the
GbE Switch Module
provides redundancy between routers in a LAN. This is accomplished by configuring the same virtual router IP address and ID number on each participating VRRP-capable routing device. One of the virtual routers is then elected as the master, based on a number of priority criteria, and assumes control of the shared virtual router IP address. If the master fails, one of the backup virtual routers will assume routing authority and take control of the virtual router IP address.
The statistics for the VRRP LAN are displayed:

Viewing, Applying, and Saving Changes
As you use the configuration menus to set switch parameters, the changes you make do not take effect immediately. All changes are considered “pending” until you explicitly apply them.
Also, any changes are lost the next time the switch boots unless the changes are explicitly saved.
N
OTE
– Some operations can override the settings in the Configuration menu. Therefore, settings you view in the Configuration menu (for example, port status) might differ from run-time information that you view in the Information menu or on the management module. The Information menu displays current run-time information of switch parameters.
While configuration changes are in the pending state, you can do the following:
View the pending changes
Apply the pending changes
Save the changes to flash memory
Viewing Pending Changes
You can view all pending configuration changes by entering
diff
at the menu prompt.
N
OTE
– The diff command is a global command. Therefore, you can enter diff at any prompt in the CLI.
Applying Pending Changes
To make your configuration changes active, you must apply them. To apply configuration changes, enter
apply
at any prompt in the CLI.
# apply
N
OTE
– The apply command is a global command. Therefore, you can enter apply at any prompt in the administrative interface.

Saving the Configuration
In addition to applying the configuration changes, you can save them to flash memory on the
GbE Switch Module
.
N
OTE
– If you do not save the changes, they will be lost the next time the system is rebooted.
To save the new configuration, enter the following command at any CLI prompt:
# save
When you save configuration changes, the changes are saved to the active configuration block.
The configuration being replaced by the save is first copied to the backup configuration block.
If you do not want the previous configuration block copied to the backup configuration block, enter the following instead:
# save n
You can decide which configuration you want to run the next time you reset the switch. Your options include:
The active configuration block
The backup configuration block
Factory default configuration
You can view all pending configuration changes that have been applied but not saved to flash memory using the diff flash command. It is a global command that can be executed from any menu.

/cfg/sys/tacacs+
TACACS+ Server Configuration
TACACS (Terminal Access Controller Access Control system) is an authentication protocol that allows a remote access server to forward a user's logon password to an authentication server to determine whether access can be allowed to a given system. TACACS is an encryption protocol, and therefore less secure than TACACS+ and Remote Authentication
Dial-In User Service (RADIUS) protocols. (Both TACACS and TACACS+ are described in
RFC 1492.)
TACACS+ protocol is more reliable than RADIUS, as TACACS+ uses the Transmission Control Protocol (TCP) whereas RADIUS uses the User Datagram Protocol (UDP). Also,
RADIUS combines authentication and authorization in a user profile, whereas TACACS+ separates the two operations.
TACACS+ offers the following advantages over RADIUS as the authentication device:
TACACS+ is TCP-based, so it facilitates connection-oriented traffic.
It supports full-packet encryption, as opposed to password-only in authentication requests.
It supports de-coupled authentication, authorization, and accounting.

Table 6-41 CIST Port Configuration Menu Options (/cfg/l2/mrst/cist/port)
Command Syntax and Usage prior
<0-240>
Configures the CIST port priority. The port priority helps determine which bridge port becomes the designated port. In a network topology that has multiple bridge ports connected to a single segment, the port with the lowest port priority becomes the designated port for the segment.
The range is 0 to 240, in steps of 16 (0, 16, 32...), and the default is 128.
cost
<0-200000000>
Configures the CIST port path cost. The port path cost is used to help determine the designated port for a segment. Generally speaking, the faster the port, the lower the path cost.
The default is 2000 for 10 Gigabit ports, 20000 for Gigabit ports.
hello
<1-10 seconds>
Configures the CIST port Hello time.The Hello time specifies how often the root bridge transmits a configuration bridge protocol data unit (BPDU). Any bridge that is not the root bridge uses the root bridge Hello value. The range is 1 to 10 seconds, and the default is 2 seconds.
link
<auto, p2p, or shared; default: auto>
Defines the type of link connected to the port, as follows:
auto
: Configures the port to detect the link type, and automatically match its settings.
p2p
: Configures the port for Point-To-Point protocol.
shared
: Configures the port to connect to a shared medium (usually a hub).

Bridge aging time
Table 6-43 Spanning Tree Bridge Menu Options (/cfg/l2/stg/brg)
Command Syntax and Usage prior
<new bridge priority (0-65535)>
Configures the bridge priority. The bridge priority parameter controls which bridge on the network is the STG root bridge. To make this switch the root bridge, configure the bridge priority lower than all other switches and bridges on your network. The lower the value, the higher the bridge priority. The range is 0 to 65535, and the default is 32768.
RSTP/MSTP: The range is 0 to 61440, in steps of 4096 (0, 4096, 8192...), and the default is 32768.
hello
<new bridge hello time (1-10 secs)>
Configures the bridge hello time.The hello time specifies how often the root bridge transmits a configuration bridge protocol data unit (BPDU). Any bridge that is not the root bridge uses the root bridge hello value. The range is 1 to 10 seconds, and the default is 2 seconds.
This command does not apply to MSTP (see CIST on
mxage
<new bridge max age (6-40 secs)>
Configures the bridge maximum age. The maximum age parameter specifies the maximum time the bridge waits without receiving a configuration bridge protocol data unit before it re configures the STG network. The range is 6 to 40 seconds, and the default is 20 seconds.
This command does not apply to MSTP (see CIST on

Table 6-43 Spanning Tree Bridge Menu Options (/cfg/l2/stg/brg)
Command Syntax and Usage fwd
<new bridge Forward Delay (4-30 secs)>
Configures the bridge forward delay parameter. The forward delay parameter specifies the amount of time that a bridge port has to wait before it changes from the listening state to the learning state and from the learning state to the forwarding state. The range is 4 to 30 seconds, and the default is
15 seconds.
This command does not apply to MSTP (see CIST on
aging
<new bridge Aging Time (1-65535 secs, 0 to disable)>
Configures the forwarding database aging time. The aging time specifies the amount of time the bridge waits without receiving a packet from a station before removing the station from the forwarding database. The range is 1 to 65535 seconds, and the default is 300 seconds. To disable aging, set this parameter to 0.

The port option of STG is turned on by default.
Table 6-44 Spanning Tree Port Menu Options (/cfg/l2/stg/port)
Command Syntax and Usage prior
<new port Priority (0-255)>
Configures the port priority. The port priority helps determine which bridge port becomes the designated port. In a network topology that has multiple bridge ports connected to a single segment, the port with the lowest port priority becomes the designated port for the segment. The default value is 128.
RSTP/MSTP: The range is 0 to 240, in steps of 16 (0, 16, 32...) and the default is 128.
cost
<new port Path Cost (1-65535, 0 for default)>
Configures the port path cost. The port path cost is used to help determine the designated port for a segment. Generally speaking, the faster the port, the lower the path cost. The default is 19 for
100Mbps ports, 4 for 1Gb ports. A value of 0 (zero) indicates that the default cost will be computed for an auto negotiated link speed.
link
<auto, p2p, or shared; default: auto>
Defines the type of link connected to the port, as follows:
auto
: Configures the port to detect the link type, and automatically match its settings.
p2p
: Configures the port for Point-To-Point protocol.
shared
: Configures the port to connect to a shared medium (usually a hub).

ARP Configuration
Address Resolution Protocol (ARP) is the TCP/IP protocol that resides within the Internet layer. ARP resolves a physical address from an IP address. ARP queries machines on the local network for their physical addresses. ARP also maintains IP to physical address pairs in its cache memory. In any IP communication, the ARP cache is consulted to see if the IP address of the computer or the router is present in the ARP cache. Then the corresponding physical address is used to send a packet.

ARP Static Configuration
Static ARP entries are permanent in the ARP cache and do not age out like the ARP entries that are learnt dynamically. Static ARP entries enable the switch to reach the hosts without sending an ARP broadcast request to the network. Static ARPs are also useful to communicate with devices that do not respond to ARP requests. Static ARPs can also be configured on some gateways as a protection against malicious ARP Cache corruption and possible DOS attacks.

type transit|stub|nssa
Defines the type of area. For example, when a virtual link has to be established with the backbone, the area type must be defined as transit.
Transit area: allows area summary information to be exchanged between routing devices. Any area that is not a stub area or NSSA is considered to be transit area.
Stub area: is an area where external routing information is not distributed. Typically, a stub area is connected to only one other area.
NSSA: Not-So-Stubby Area (NSSA) is similar to stub area with additional capabilities. For example, routes originating from within the NSSA can be propagated to adjacent transit and backbone areas. External routes from outside the Autonomous System (AS) can be advertised within the
NSSA but are not distributed into other areas.
metric
<metric value (1-65535)>
Configures a stub area to send a numeric metric value. All routes received via that stub area carry the configured metric to potentially influencing routing decisions.
Metric value assigns the priority for choosing the switch for default route. Metric type determines the method for influencing routing decisions for external routes.
auth none|password|md5
None: No authentication required.
Password: Authenticates simple passwords so that only trusted routing devices can participate.

Border Gateway Protocol (BGP) is an Internet protocol that enables routers on a network to share routing information with each other and advertise information about the segments of the
IP address space they can access within their network with routers on external networks. BGP allows you to decide what is the “best” route for a packet to take from your network to a destination on another network, rather than simply setting a default route from your border router(s) to your upstream provider(s). You can configure BGP either within an autonomous system or between different autonomous systems. When run within an autonomous system, it's called internal BGP (iBGP). When run between different autonomous systems, it's called external
BGP (eBGP). BGP is defined in RFC 1771.
BGP commands enable you to configure the switch to receive routes and to advertise static routes, fixed routes and virtual server IP addresses with other internal and external routers. In the current Alteon OS implementation, the
GbE Switch Module
does not advertise BGP routes that are learned from one iBGP speaker to another iBGP speaker.
BGP is turned off by default.

– Fixed routes are subnet routes. There is one fixed route per IP interface.

orig
<min orig time (1-65535)>

ttl
<number of router hops (1-255)>
Time-to-live (TTL) is a value in an IP packet that tells a network router whether or not the packet has been in the network too long and should be discarded. TTL specifies a certain time span in seconds that, when exhausted, would cause the packet to be discarded. The TTL is determined by the number of router hops the packet is allowed before it must be discarded.
This command specifies the number of router hops that the IP packet can make. This value is used to restrict the number of “hops” the advertisement makes. It is also used to support multi-hops, which allow BGP peers to talk across a routed network. The default number is set at 1.
Note: The TTL value is significant only to eBGP peers, for iBGP peers the TTL value in the IP packets is always 255 (regardless of the confiogured value).

Virtual Router Redundancy Protocol (VRRP) support on
GbE Switch Module s provides redundancy between routers in a LAN. This is accomplished by configuring the same virtual router IP address and ID number on each participating VRRP-capable routing device. One of the virtual routers is then elected as the master, based on a number of priority criteria, and assumes control of the shared virtual router IP address. If the master fails, one of the backup virtual routers will assume routing authority and take control of the virtual router IP address.
By default, VRRP is disabled. Alteon OS has extended VRRP to include virtual servers as well, allowing for full active/active redundancy between switches. For more information on

On each VRRP-capable routing device participating in redundancy for this virtual router, a virtual router will be configured to share the same virtual router ID and IP address.
Virtual routers are disabled by default.

vrid
<virtual router ID (1-1024)>
Defines the virtual router ID. This is used in conjunction with addr (below) to define a virtual router on this switch. To create a pool of VRRP-enabled routing devices which can provide redundancy to each other, each participating VRRP device must be configured with the same virtual router: one that shares the same vrid and addr combination.
The vrid for virtual routers (where the virtual router IP address is not the same as any virtual server) can be any integer between 1 and 1024. The default value is 1.
All vrid values must be unique within the VLAN to which the virtual router’s IP interface belongs.
addr
<IP address (such as, 192.4.17.101)>
Defines the IP address for this virtual router using dotted decimal notation. This is used in conjunction with the vrid (above) to configure the same virtual router on each participating VRRP device. The default address is 0.0.0.0.

Table 6-98 VRRP Virtual Router Menu Options (/cfg/l3/vrrp/vr)
Command Syntax and Usage if
<interface number (1-127)>
Selects a switch IP interface. If the IP interface has the same IP address as the addr option above, this switch is considered the “owner” of the defined virtual router. An owner has a special priority of 255 (highest) and will always assume the role of master router, even if it must preempt another virtual router which has assumed master routing authority. This preemption occurs even if the preem
option below is disabled. The default value is 1.
prio
<priority (1-254)>
Defines the election priority bias for this virtual server. This can be any integer between 1 and 254.
The default value is 100.
During the master router election process, the routing device with the highest virtual router priority number wins. If there is a tie, the device with the highest IP interface address wins. If this virtual router’s IP address (addr) is the same as the one used by the IP interface, the priority for this virtual router will automatically be set to 255 (highest).
When priority tracking is used (/cfg/l3/vrrp/track or /cfg/l3/vrrp/vr #/track), this base priority value can be modified according to a number of performance and operational criteria.
adver
<seconds (1-255)>
Defines the time interval between VRRP master advertisements. This can be any integer between 1 and 255 seconds. The default value is 1.
preem disable|enable
Enables or disables master preemption. When enabled, if this virtual router is in backup mode but has a higher priority than the current master, this virtual router will preempt the lower priority master and assume control. Note that even when preem is disabled, this virtual router will always preempt any other master if this switch is the owner (the IP interface address and virtual router addr are the same). By default, this option is enabled.

Virtual Router Priority Tracking Configuration
[VRRP Virtual Router 1 Priority Tracking Menu]
vrs - Enable/disable tracking master virtual routers
ifs - Enable/disable tracking other interfaces
ports - Enable/disable tracking VLAN switch ports
cur - Display current VRRP virtual router configuration
This menu is used for modifying the priority system used when electing the master router from a pool of virtual routers. Various tracking criteria can be used to bias the election results. Each time one of the tracking criteria is met, the priority level for the virtual router is increased by an amount defined through the VRRP Tracking Menu (see
).
Criteria are tracked dynamically, continuously updating virtual router priority levels when
enabled. If the virtual router preemption option (see preem in Table 6-98 on page 300 ) is
enabled, this virtual router can assume master routing authority when its priority level rises above that of the current master.
Some tracking criteria (vrs, ifs, and ports below) apply to standard virtual routers, otherwise called “virtual interface routers.” A virtual server router is defined as any virtual router whose IP address (addr) is the same as any configured virtual server IP address.
Table 6-99 Virtual Router Priority Tracking Menu Options (/cfg/l3/vrrp/vr #/track)
Command Syntax and Usage
vrs disable|enable
When enabled, the priority for this virtual router will be increased for each virtual router in master mode on this switch. This is useful for making sure that traffic for any particular client/server pairing are handled by the same switch, increasing routing and load balancing efficiency. This command is disabled by default.
ifs disable|enable
When enabled, the priority for this virtual router will be increased for each other IP interface active on this switch. An IP interface is considered active when there is at least one active port on the same VLAN. This helps elect the virtual routers with the most available routes as the master. This command is disabled by default.
ports disable|enable
When enabled, the priority for this virtual router will be increased for each active port on the same
VLAN. A port is considered “active” if it has a link and is forwarding traffic. This helps elect the virtual routers with the most available ports as the master. This command is disabled by default.

Restoring the Active Switch Configuration
When the gtcfg command is used, the active configuration will be replaced with the commands found in the specified configuration file. The file can contain a full switch configuration or a partial switch configuration. The configuration loaded using gtcfg is not activated until the apply command is used. If the apply command is found in the configuration script file loaded using this command, the apply action will be performed automatically.
To start the switch configuration download, at the Configuration# prompt, enter:
Configuration# gtcfg

The Operations Menu
The Operations Menu is generally used for commands that affect switch performance immediately, but do not alter permanent switch configurations. For example, you can use the Operations Menu to immediately disable a port (without the need to apply or save the change), with the understanding that when the switch is reset, the port returns to its normally configured operation.

Forces the specified master virtual router on this switch into backup mode. This is generally used for passing master control back to a preferred switch once the preferred switch has been returned to service after a failure. When this command is executed, the current master gives up control and initiates a new election by temporarily advertising its own priority level as 0 (lowest). After the new election, the virtual router forced into backup mode by this command will resume master control in the following cases:
This switch owns the virtual router (the IP addresses of the virtual router and its IP interface are the same)
This switch’s virtual router has a higher priority and preemption is enabled.
There are no other virtual routers available to take master control.

Alteon OS Command Reference
Updating the Switch Software Image
The switch software image is the executable code running on the
GbE Switch Module
. A version of the image ships with the switch, and comes pre-installed on the device. As new versions of the image are released, you can upgrade the software running on your switch. To get the latest version of software available for your GbE Switch Module, go to: http://www-304.ibm.com/jct01004c/systems/support
Click on software updates. Use the /boot/cur command to determine the current software version.
The typical upgrade process for the software image consists of the following steps:
Place the new image onto a FTP or TFTP server on your network, or on a local computer.
Transfer the new image to your switch.
Select the new software image to be loaded into switch memory the next time the switch is reset.
Loading New Software to Your Switch
The switch can store up to two different software images, called image1 and image2, as well as boot software, called boot. When you load new software, you must specify where it should be placed: either into image1, image2, or boot.
For example, if your active image is currently loaded into image1, you would probably load the new image software into image2. This lets you test the new software and reload the original active image (stored in image1), if needed.
Using the BBI
You can use the Browser-Based Interface to load software onto the GbESM. The software image to load can reside in one of the following locations:
FTP server
TFTP server
Local computer
After you log onto the BBI, perform the following steps to load a software image:
1.
Click the Configure context button in the toolbar.
2.
In the Navigation Window, select System > Config/Image Control.

/maint/uudmp
Uuencode Flash Dump
Using this command, dump information is presented in uuencoded format. This format makes it easy to capture the dump information as a file or a string of characters.
If you want to capture dump information to a file, set your communication software on your workstation to capture session data prior to issuing the uudmp command. This will ensure that you do not lose any information. Once entered, the uudmp command will cause approximately
23,300 lines of data to be displayed on your screen and copied into the file.
Using the uudmp command, dump information can be read multiple times. The command does not cause the information to be updated or cleared from flash memory.
N
OTE
– Dump information is not cleared automatically. In order for any subsequent dump information to be written to flash memory, you must manually clear the dump region. For more
information on clearing the dump region, see page 354 .
To access dump information, at the Maintenance# prompt, enter:
Maintenance# uudmp
The dump information is displayed on your screen and, if you have configured your communication software to do so, captured to a file. If the dump region is empty, the following appears:
No FLASH dump available.

Use this command to put (save) the system dump to a TFTP server.
N
OTE
– If the TFTP server is running SunOS or the Solaris operating system, the specified ptdmp
file must exist prior to executing the ptdmp command, and must be writable (set with proper permission, and not locked by any application). The contents of the specified file will be replaced with the current dump data.
To save dump information via TFTP, at the Maintenance# prompt, enter:
Maintenance# ptdmp
<server> <filename>
Where server is the TFTP server IP address or hostname, and filename is the target dump file.
/maint/cldmp
Clearing Dump Information
To clear dump information from flash memory, at the Maintenance# prompt, enter:
Maintenance# cldmp
The switch clears the dump region of flash memory and displays the following message:
FLASH dump region cleared.
If the flash dump region is already clear, the switch displays the following message:
FLASH dump region is already clear.

Alteon OS SNMP Agent
The Alteon OS SNMP agent supports SNMP version 3. Security is provided through SNMP community strings. The default community strings are “public” for SNMP GET operation and
“private” for SNMP SET operation. The community string can be modified only through the
Command Line Interface (CLI). Alteon WebSystems is registered as Vendor 1872. Detailed
SNMP MIBs and trap definitions of the Alteon OS SNMP agent are contained in the following
Alteon OS enterprise MIB document:
GbESM-1G-2223.mib
Users may specify up to two trap hosts for receiving SNMP Traps. The agent will send the
SNMP Trap to the specified hosts when appropriate. Traps are not sent if there is no host specified.
Alteon OS SNMP agent supports the following standard MIBs:
rfc1213.mib
rfc1215.mib
rfc1493.mib
rfc1573.mib
rfc1643.mib

The following are the enterprise SNMP traps supported in Alteon OS:
Table 9-10 Alteon OS-Supported Enterprise SNMP Traps
Trap Name Description
altSwPrimaryPowerSupplyFailure Signifies that the primary power supply failed. altSwFanFailure Signifies that the fan has failed. altSwDefGwUp altSwDefGwDown altSwDefGwInService altSwDefGwNotInService altSwVrrpNewMaster altSwVrrpNewBackup altSwVrrpAuthFailure altSwLoginFailure
Signifies that the default gateway is alive.
Signifies that the default gateway is down.
Signifies that the default gateway is up and in service
Signifies that the default gateway is alive but not in service
The newMaster trap indicates that the sending agent has transitioned to 'Master' state.
The newBackup trap indicates that the sending agent has transitioned to 'Backup' state.
A vrrpAuthFailure trap signifies that a packet has been received from a router whose authentication key or authentication type conflicts with this router's authentication key or authentication type. Implementation of this trap is optional.
A altSwLoginFailure trap signifies that someone failed to enter a valid username/password combination.

Any time an IP address is changed from one source IP or destination IP address to another address, network address translation can be said to have taken place. In general, half NAT is when the destination IP or source IP address is changed from one address to another.
Full NAT is when both addresses are changed from one address to another. No NAT is when neither source nor destination IP addresses are translated.
Preemption
In VRRP, preemption will cause a Virtual Router that has a lower priority to go into backup should a peer Virtual Router start advertising with a higher priority.
Priority
Proto (Protocol)
In VRRP, the value given to a Virtual Router to determine its ranking with its peer(s). Minimum value is 1 and maximum value is 254. Default is 100. A higher number will win out for master designation.
The protocol of a frame. Can be any value represented by a 8-bit value in the IP header adherent to the IP specification (for example, TCP, UDP, OSPF, ICMP, and so on.)
SIP (Source IP Address)
The source IP address of a frame.
SPort (Source Port)
The source port (application socket: for example, HTTP-80/HTTPS-443/DNS-53).
Tracking
In VRRP, a method to increase the priority of a virtual router and thus master designation
(with preemption enabled). Tracking can be very valuable in an active/active configuration.
You can track the following:
ifs: Active IP interfaces on the GbE Switch Module (increments priority by 2 for each)
ports: Active ports on the same VLAN (increments priority by 2 for each)
vrs: Number of virtual routers in master mode on the switch

VIR (Virtual Interface
Router)
A VRRP address that is an IP interface address shared between two or more virtual routers.
Virtual Router
VRID (Virtual Router
Identifier)
A shared address between two devices utilizing VRRP, as defined in RFC 2338. One virtual router is associated with an IP interface. This is one of the IP interfaces that the switch is assigned. All IP interfaces on the GbE Switch Module must be in a VLAN. If there is more than one VLAN defined on the GbE Switch Module, then the VRRP broadcasts will only be sent out on the VLAN of which the associated IP interface is a member.
In VRRP, a value between 1 and 1024 that is used by each virtual router to create its MAC address and identify its peer for which it is sharing this VRRP address. The standard
VRRP MAC address as defined in the RFC is 00-00-5E-00-01-{VRID}. For virtual routers with a VRID greater than 255, the following block of MAC addresses is allocated:
00:0F:6A:9A:40:00 - 00:0F:6A:9A:47:FF
If you have a VRRP address shared between two switches, then the VRID must be identical on both switches so each virtual router on each switch knows with whom to share.
VRRP (Virtual Router
Redundancy Protocol)
A protocol that acts very similarly to Cisco's proprietary HSRP address sharing protocol.
The reason for both of these protocols is so devices have a next hop or default gateway that is always available. Two or more devices sharing an IP interface are either advertising or listening for advertisements. These advertisements are sent via a broadcast message to an address such as 224.0.0.18.
With VRRP, one switch is considered the master and the other the backup. The master is always advertising via the broadcasts. The backup switch is always listening for the broadcasts. Should the master stop advertising, the backup will take over ownership of the
VRRP IP and MAC addresses as defined by the specification. The switch announces this change in ownership to the devices around it by way of a Gratuitous ARP, and advertisements. If the backup switch didn't do the Gratuitous ARP the Layer 2 devices attached to the switch would not know that the MAC address had moved in the network. For a more detailed description, refer to RFC 2338.
