Preface
Obtaining Technical Assistance
Technical Assistance Center
The Cisco TAC is available to all customers who need technical assistance with a Cisco product,
technology, or solution. Two types of support are available: the Cisco TAC website and the Cisco TAC
Escalation Center. The type of support that you choose depends on the priority of the problem and the
conditions stated in service contracts, when applicable.
We categorize Cisco TAC inquiries according to urgency:
•
Priority level 4 (P4)—You need information or assistance concerning Cisco product capabilities,
product installation, or basic product configuration. There is little or no impact to your business
operations.
•
Priority level 3 (P3)—Operational performance of the network is impaired, but most business
operations remain functional. You and Cisco are willing to commit resources during normal
business hours to restore service to satisfactory levels.
•
Priority level 2 (P2)—Operation of an existing network is severely degraded, or significant aspects
of your business operations are negatively impacted by inadequate performance of Cisco products.
You and Cisco will commit full-time resources during normal business hours to resolve the
situation.
•
Priority level 1 (P1)—An existing network is “down,” or there is a critical impact to your business
operations. You and Cisco will commit all necessary resources around the clock to resolve the
situation.
Cisco TAC Website
The Cisco TAC website provides online documents and tools to help troubleshoot and resolve technical
issues with Cisco products and technologies. To access the Cisco TAC website, go to this URL:
http://www.cisco.com/tac
All customers, partners, and resellers who have a valid Cisco service contract have complete access to
the technical support resources on the Cisco TAC website. Some services on the Cisco TAC website
require a Cisco.com login ID and password. If you have a valid service contract but do not have a login
ID or password, go to this URL to register:
http://tools.cisco.com/RPF/register/register.do
If you are a Cisco.com registered user, and you cannot resolve your technical issues by using the Cisco
TAC website, you can open a case online at this URL:
http://www.cisco.com/tac/caseopen
If you have Internet access, we recommend that you open P3 and P4 cases online so that you can fully
describe the situation and attach any necessary files.
Cisco TAC Escalation Center
The Cisco TAC Escalation Center addresses priority level 1 or priority level 2 issues. These
classifications are assigned when severe network degradation significantly impacts business operations.
When you contact the TAC Escalation Center with a P1 or P2 problem, a Cisco TAC engineer
automatically opens a case.

Command-Line Interface
Using the No and Default Forms of Commands
Using the No and Default Forms of Commands
Almost every configuration command has a no form. In general, enter the no form to disable a function.
Use the command without the keyword no to reenable a disabled function or to enable a function that is
disabled by default. For example, IP routing is enabled by default. To disable IP routing, specify the
no ip routing command and specify ip routing to reenable it. This publication provides the complete
syntax for the configuration commands and describes what the no form of a command does.
Configuration commands can have a default form. The default form of a command returns the command
setting to its default. Most commands are disabled by default, so the default form is the same as the no
form. However, some commands are enabled by default and have variables set to certain default values.
In these cases, the default form of the command enables the command and sets variables to their default
values. This publication describes what the default form of a command does if the command is not the
same as the no form.
Using the CLI String Search
The pattern in the command output is referred to as a string. The CLI string search feature allows you to
search or filter any show or more command output and allows you to search and filter at --More-prompts. This feature is useful when you need to sort though large amounts of output, or if you want to
exclude output that you do not need to see.
With the search function, you can begin unfiltered output at the first line that contains a regular
expression you specify. You can then specify a maximum of one filter per command or start a new search
from the --More-- prompt.
A regular expression is a pattern (a phrase, number, or more complex pattern) software uses to match
against show or more command output. Regular expressions are case sensitive and allow for complex
matching requirements. Examples of simple regular expressions are Serial, misses, and 138. Examples
of complex regular expressions are 00210..., ( is ), and [Oo]utput.
You can perform three types of filtering:
•
Use the begin keyword to begin output with the line that contains a specified regular expression.
•
Use the include keyword to include output lines that contain a specified regular expression.
•
Use the exclude keyword to exclude output lines that contain a specified regular expression.
You can then search this filtered output at the --More-- prompts.
Note
The CLI string search function does not allow you to search or filter backward through previous output;
filtering cannot be specified using HTTP access to the CLI.
Regular Expressions
A regular expression can be a single character that matches the same single character in the command
output or multiple characters that match the same multiple characters in the command output. This
section describes how to create both single-character patterns and multiple-character patterns and how
to create more complex regular expressions using multipliers, alternation, anchoring, and parentheses.

Command-Line Interface
Using the CLI String Search
Single-Character Patterns
The simplest regular expression is a single character that matches the same single character in the
command output. You can use any letter (A-Z, a-z) or digit (0-9) as a single-character pattern. You can
also use other keyboard characters (such as ! or ~) as single-character patterns, but certain keyboard
characters have special meaning when used in regular expressions. Table 1-3 lists the keyboard
characters with special meaning.
Table 1-3
Characters with Special Meaning

.
Matches any single character, including white space.
*
Matches 0 or more sequences of the pattern.
+
Matches 1 or more sequences of the pattern.
?
Matches 0 or 1 occurrences of the pattern.
^
Matches the beginning of the string.
$
Matches the end of the string.
_ (underscore)
Matches a comma (,), left brace ({), right brace (}), left parenthesis ( ( ),
right parenthesis ( ) ), the beginning of the string, the end of the string, or a
space.
To enter these special characters as single-character patterns, remove the special meaning by preceding
each character with a backslash (\). These examples are single-character patterns matching a dollar sign,
an underscore, and a plus sign, respectively.
\$ \_ \+
You can specify a range of single-character patterns to match against command output. For example,
you can create a regular expression that matches a string containing one of the following letters: a, e, i,
o, or u. One and only one of these characters must exist in the string for pattern matching to succeed. To
specify a range of single-character patterns, enclose the single-character patterns in square brackets
([ ]). For example,
[aeiou]
matches any one of the five vowels of the lowercase alphabet, while
[abcdABCD]
matches any one of the first four letters of the lower- or uppercase alphabet.
You can simplify ranges by entering only the end points of the range separated by a dash (-). Simplify
the previous range as follows:
[a-dA-D]
To add a dash as a single-character pattern in your range, include another dash and precede it with a
backslash:
[a-dA-D\-]
You can also include a right square bracket (]) as a single-character pattern in your range. To do so, enter
the following:
[a-dA-D\-\]]

Command-Line Interface
Using the CLI String Search
The previous example matches any one of the first four letters of the lower- or uppercase alphabet, a
dash, or a right square bracket.
You can reverse the matching of the range by including a caret (^) at the start of the range. This example
matches any letter except the ones listed:
[^a-dqsv]
This example matches anything except a right square bracket (]) or the letter d:
[^\]d]
Multiple-Character Patterns
When creating regular expressions, you can also specify a pattern containing multiple characters. You
create multiple-character regular expressions by joining letters, digits, or keyboard characters that do not
have special meaning. For example, a4% is a multiple-character regular expression. Put a backslash in
front of the keyboard characters that have special meaning when you want to remove their special
meaning.
With multiple-character patterns, order is important. The regular expression a4% matches the character
a followed by a 4 followed by a % sign. If the string does not have a4%, in that order, pattern matching
fails. This multiple-character regular expression
a.
uses the special meaning of the period character to match the letter a followed by any single character.
With this example, the strings ab, a!, or a2 are all valid matches for the regular expression.
You can remove the special meaning of the period character by putting a backslash in front of it. In the
following expression
a\.
only the string a. matches this regular expression.
You can create a multiple-character regular expression containing all letters, all digits, all keyboard
characters, or a combination of letters, digits, and other keyboard characters. These examples are all
valid regular expressions:
telebit 3107 v32bis
Multipliers
You can create more complex regular expressions to match multiple occurrences of a specified regular
expression by using some special characters with your single- and multiple-character patterns. Table 1-4
lists the special characters that specify “multiples” of a regular expression.
Table 1-4
Special Characters Used as Multipliers
Character
Description
*
Matches 0 or more single- or multiple-character patterns.
+
Matches 1 or more single- or multiple-character patterns.
?
Matches 0 or 1 occurrences of the single- or multiple-character patterns.
This example matches any number of occurrences of the letter a, including none:
a*

Chapter 1
Command-Line Interface
Using the CLI String Search
This pattern requires that at least one letter a in the string is matched:
a+
This pattern matches the string bb or bab:
ba?b
This string matches any number of asterisks (*):
\**
To use multipliers with multiple-character patterns, you enclose the pattern in parentheses. In the
following example, the pattern matches any number of the multiple-character string ab:
(ab)*
As a more complex example, this pattern matches one or more instances of alphanumeric pairs (but not
none; that is, an empty string is not a match):
([A-Za-z][0-9])+
The order for matches using multipliers (*, +, or ?) is to put the longest construct first. Nested constructs
are matched from outside to inside. Concatenated constructs are matched beginning at the left side of
the construct. Thus, the regular expression matches A9b3, but not 9Ab3 because the letters are specified
before the numbers.
Alternation
Alternation allows you to specify alternative patterns to match against a string. You separate the
alternative patterns with a vertical bar (|). Exactly one of the alternatives can match the string. For
example, the regular expression
codex | telebit
matches the string codex or the string telebit, but not both codex and telebit.
Anchoring
You can match a regular expression pattern against the beginning or the end of the string. That is, you
can specify that the beginning or end of a string contains a specific pattern. You “anchor” these regular
expressions to a portion of the string using the special characters shown in Table 1-5.
Table 1-5
Special Characters Used for Anchoring
Character
Description
^
Matches the beginning of the string.
$
Matches the end of the string.
This regular expression matches a string only if the string starts with abcd:
^abcd
In contrast, this expression is in a range that matches any single letter, as long as it is not the letters a,
b, c, or d:
[^abcd]

OL-3354-01
Chapter 1
Command-Line Interface
Using the CLI String Search
With this example, the regular expression matches a string that ends with .12:
$\.12
Contrast these anchoring characters with the special character underscore (_). The underscore matches
the beginning of a string (^), the end of a string ($), parentheses ( ), space ( ), braces { }, comma (,), or
underscore (_). With the underscore character, you can specify that a pattern exist anywhere in the string.
For example:
_1300_
matches any string that has 1300 somewhere in the string. The string’s 1300 can be preceded by or end
with a space, brace, comma, or underscore. For example:
{1300_
matches the regular expression, but 21300 and 13000 do not.
Using the underscore character, you can replace long regular expression lists, such as the following:
^1300$ ^1300(space) (space)1300 {1300, ,1300, {1300} ,1300, (1300
with
_1300_
Parentheses for Recall
As shown in the “Multipliers” section on page 1-7, you use parentheses with multiple-character regular
expressions to multiply the occurrence of a pattern. You can also use parentheses around a single- or
multiple-character pattern to remember a pattern for use elsewhere in the regular expression.
To create a regular expression that recalls a previous pattern, you use parentheses to indicate a
remembered specific pattern and a backslash (\) followed by an integer to reuse the remembered pattern.
The integer specifies the occurrence of the parentheses in the regular expression pattern. If you have
more than one remembered pattern in your regular expression, then \1 indicates the first remembered
pattern, \2 indicates the second remembered pattern, and so on.
This regular expression uses parentheses for recall:
a(.)bc(.)\1\2
This regular expression matches an a followed by any character (call it character 1), followed by bc
followed by any character (character 2), followed by character 1 again, followed by character 2 again.
The regular expression can match aZbcTZT. The software remembers that character 1 is Z and character
2 is T and then uses Z and T again later in the regular expression.
alt Keyword Usage
When you enable high-availability redundancy, every configuration command executed on the
designated MSFC is sent to the nondesignated MSFC. Also, the running configuration synchronization
is updated when you enter the copy source running-config command on the designated MSFC.

The two states for the configuration synchronization are as follows:
•
Config Sync AdminStatus—Signifies what the user has configured for this feature at that moment
•
Config Sync RuntimeStatus—Enabled only when the following occurs:
– The Config Sync AdminStatus is enabled on both the designated and nondesignated MSFCs
– The designated and nondesignated MSFCs are running compatible images
To configure both MSFCs from a single console, enter the alt keyword to specify an alternate
configuration. When specifying the alternate configuration, the configuration that is specified before the
alt keyword relates to the MSFC on the supervisor engine in slot 1 of the switch; the configuration that
is specified after the alt keyword relates to the MSFC on the supervisor engine in slot 2.
Note
You must enter the alt keyword when you enable Config Sync AdminStatus.
When you enable the Config Sync RuntimeStatus, the following occurs:
•
No configuration mode is available on the CLI of the nondesignated MSFC; EXEC mode is
available. Configuration of both MSFCs is made through the console or a Telnet session on the
designated MSFC.
•
The alt keyword is available and required (see the “alt Keyword Usage” section on page 1-9 for
more information on the alt keyword)
•
The running and startup configurations are synchronized
When the Config Sync RuntimeStatus is in disabled mode, the following occurs:
•
Configuration mode is available on the CLI of both MSFCs
•
The alt keyword is available but optional
•
The running and startup configurations are not synchronized
Table 1-6 shows the interface and global configuration commands that contain the alt keyword:

Saving Configuration Changes
To save your configuration changes to your startup configuration so that they will not be lost if there is
a system reload or power outage, enter the following command:
Router# copy system:running-config nvram:startup-config
Building configuration...
It might take a minute or two to save the configuration. After the configuration has been saved, the
following output appears:
[OK]

On most platforms, this step saves the configuration to NVRAM. On the Class A Flash file system
platforms, this step saves the configuration to the location specified by the CONFIG_FILE environment
variable. The CONFIG_FILE environment variable defaults to NVRAM.
MSFC CLI
You can access the Multilayer Switch Feature Card (MSFC) command-line interface (CLI) by entering
commands from the supervisor engine CLI. These sections describe the MSFC CLI:

You can enter the session mod command to access the MSFC CLI from the supervisor engine CLI using
a Telnet session. To exit from the MSFC CLI back to the supervisor engine CLI, enter the exit command
at the Router> prompt.
Note
The supervisor engine software sees the MSFC as module 15 (when installed on a
supervisor engine in slot 1) or module 16 (when installed on a supervisor engine in slot 2).
This example shows how to access the MSFC from the supervisor engine CLI, and how to exit the MSFC
CLI and return to the supervisor engine CLI:

Cisco IOS Command Modes
The Cisco IOS user interface is divided into many different modes. The commands available to you
depend on which mode you are currently in. To get a list of the commands in a given mode, type a
question mark (?) at the system prompt. For more information, see the “Getting a List of Cisco IOS
Commands and Syntax” section on page 2-14.
When you start a session on the supervisor engine, you begin in user mode, often called user EXEC
mode. Only a limited subset of the commands are available in EXEC mode. To have access to all
commands, you must enter privileged EXEC mode. Normally, you must type in a password to access
privileged EXEC mode. From privileged EXEC mode, you can type in any EXEC command or access
global configuration mode. Most of the EXEC commands are one-time commands, such as show
commands, which show the current configuration status, and clear commands, which clear counters or
interfaces. The EXEC commands are not saved across reboots of the supervisor engine.

MSFC CLI
The configuration modes allow you to make changes to the running configuration. If you later save the
configuration, these commands are stored across supervisor engine reboots. You must start at global
configuration mode. From global configuration mode, you can enter interface configuration mode,
subinterface configuration mode, and a variety of protocol-specific modes.
ROM monitor mode is a separate mode used when the supervisor engine cannot boot properly. For
example, the supervisor engine might enter ROM monitor mode if it does not find a valid system image
when it is booting, or if its configuration file is corrupted at startup. For more information, see the
“Catalyst 6500 Series IOS Command Reference.”

Usage Guidelines
Hexadecimal or decimal value that represents the 16-bit configuration register
value that you want to use the next time the router is restarted; vaild values are from
0x0 to 0xFFFF (0 to 65535 in decimal).
This command applies only to platforms that use a software configuration register.
The lowest four bits of the configuration register (bits 3, 2, 1, and 0) form the boot field. The boot field
determines if the router boots manually, from ROM, or from Flash or the network.
To change the boot field value and leave all other bits set to their default values, follow these guidelines:
•
If you set the configuration register boot field value to 0x0, you must boot the operating system
manually with the boot command.
•
If you set the configuration register boot field value to 0x1, the router boots using the default ROM
software.
•
If you set the configuration register boot field to any value from 0x2 to 0xF, the router uses the boot
field value to form a default boot filename for booting from a network server.
For more information about the configuration register bit settings and default filenames, see the
appropriate router hardware installation guide.

interface range
interface range
To execute a command on multiple ports at the same time, use the interface range command.
interface range {port-range | macro name}
Syntax Description
port-range
Port range; for a list of valid values for port-range, see the “Usage
Guidelines” section.
macro name
Specifies the name of a macro.
Defaults
This command has no default settings.
Command Modes

Command History
Release
Modification
12.1E
This command was introduced on the MSFC.
Usage Guidelines
You can use the interface range command on existing VLAN SVIs only. To display VLAN SVIs, enter
the show running config command. VLANs not displayed cannot be used in the interface range
command.
The values entered with the interface range command are applied to all existing VLAN SVIs.
Before you can use a macro, you must define a range using the define interface-range command.
All configuration changes made to a port range are saved to NVRAM, but port ranges created with the
interface range command do not get saved to NVRAM.
You can enter the port range in two ways:
•
Specifying up to five port ranges
•
Specifying a previously defined macro
You can either specify the ports or the name of a port range macro. A port range must consist of the same
port type, and the ports within a range cannot span slots.
You can define up to five port ranges on a single command, with each range separated by a comma.
When you define a range, you must enter a white space between the first port and the hyphen (-):
When you define a range, you must enter a white space before and after the hyphen (-) as follows:
interface range pos 7/1 - 7, pos9/5 - 408
If your system is configured with a Supervisor Engine 1, valid values for vlan-id are from 1 to 1005. If
your system is configured with a Supervisor Engine 2, valid values for vlan-id are from 1 to 4094.
Extended-range VLANs are not supported on systems configured with a Supervisor Engine 1.

interface range
When entering the port-range, these formats can be used:
•
card-type {slot}/{first-port} - {last-port}
•
card-type {slot}/{first-port} - {last-port}
Valid values for card-type are as follows:
•
ge-wan
•
pos
•
vlan vlan-id
You cannot specify both a macro and an interface range in the same command. After creating a macro,
the CLI does not allow you to enter additional ranges. If you have already entered an interface range, the
CLI does not allow you to enter a macro.
You can also specify a single interface in port-range.
Examples
This example shows how to execute a command on two port ranges:
Router(config)# interface range pos 7/1 - 7, pos 9/5 - 408
Router(config-if)#

To set a primary or secondary IP address for an interface, use the ip address command. Use the no form
of this command to remove an IP address or disable IP processing..

Syntax Description
ip-address
IP address.
mask
Mask for the associated IP subnet.

(Optional) Specifies that the configured address is a secondary IP address. If this
keyword is omitted, the configured address is the primary IP address.
Defaults
No IP address is defined for the interface.

Modification
12.1E
This command was introduced on the MSFC.
Usage Guidelines
The alt keyword is used to specify an alternate configuration and is used in the following:
[no] ip address ip-address mask [secondary] alt [no] ip address ip-address mask [secondary]
An interface can have one primary IP address and multiple secondary IP addresses. Packets generated
by the Cisco IOS software always use the primary IP address. Therefore, all routers and access servers
on a segment should share the same primary network number.
Hosts can determine subnet masks using the Internet Control Message Protocol (ICMP) Mask Request
message. Routers respond to this request with an ICMP Mask Reply message.
You can disable IP processing on a particular interface by removing its IP address with the no ip address
command. If the software detects another host using one of its IP addresses, it will print an error message
on the console.
The optional keyword secondary allows you to specify an unlimited number of secondary addresses.
Secondary addresses are treated like primary addresses, except the system never generates datagrams
other than routing updates with secondary source addresses. IP broadcasts and ARP requests are handled
properly, as are interface routes in the IP routing table.
Secondary IP addresses can be used in a variety of situations. The following are the most common
applications:

OL-3354-01
Chapter 2
Catalyst 6500 Series Switch MSFC Commands
ip address
•
There may not be enough host addresses for a particular network segment. For example, your
subnetting allows up to 254 hosts per logical subnet, but on one physical subnet you need to have
300 host addresses. Using secondary IP addresses on the routers or access servers allows you to have
two logical subnets using one physical subnet.
•
Many older networks were built using Level 2 bridges. The judicious use of secondary addresses can
aid in the transition to a subnetted, router-based network. Routers on an older, bridged segment can
be easily made aware that there are many subnets on that segment.
•
Two subnets of a single network might otherwise be separated by another network. This situation is
not permitted when subnets are in use. In these instances, the first network is extended, or layered
on top of the second network using secondary addresses.
Note
If any router on a network segment uses a secondary address, all other devices on that same
segment must also use a secondary address from the same network or subnet. Inconsistent
use of secondary addresses on a network segment can very quickly cause routing loops.
Note
When you are routing Open Shortest Path First (OSPF), ensure that all secondary addresses
of an interface fall into the same OSPF area as the primary addresses.
To transparently bridge IP on an interface, you must do two things:
•
Disable IP routing (specify no ip routing).
•
Add the interface to a bridge group. (See the bridge-group command.)
To concurrently route and transparently bridge IP on an interface, see the bridge crb command.
Examples
In the following example, 131.108.1.27 is the primary address and 192.31.7.17 and 192.31.8.17 are
secondary addresses for Ethernet interface 0:
interface ethernet 0
ip address 131.108.1.27 255.255.255.0
ip address 192.31.7.17 255.255.255.0 secondary

Usage Guidelines
Specifies the maximum number of login attempts: valid values are from 1

This command is supported on firewall interfaces only.
The maximum login attempt functionality is independent of the watch-list feature. If you do not
configure the watch-list feature (using the ip access-list hardware permit fragments command) and
you configure the maximum login attempt functionality, the existing authentication proxy behavior
occurs but with the new number for retries. If you configure the watch-list feature, once the configured
number of attempts has been reached, the IP address is put in the watch list.

Usage Guidelines
The valid values for minutes are from 0 to the largest 32-bit positive number (0x7FFFFFFF or
2147483647 in decimal). Setting the minutes to 0 (zero) places the entries in the list permanently.
This command is supported on firewall interfaces only.
Use the no form of this command to do the following:
•
no ip auth-proxy watch-list—Disables the watch-list functionality.
•
no ip auth-proxy watch-list add-item ip-addr—Removes the IP address from the watch list.
•
no ip auth-proxy watch-list expiry-time—Returns to the default setting.
A watch list consists of IP addresses that have opened TCP connections to port 80 and have not sent any
data is implemented. No new connection are accepted from this type of IP address (to port 80) and the
packet is dropped.
The watch-list entry remains in the watch list for the time specified by expiry-time minutes.
When you disable the watch-list functionality, no entries are put into the watch list, but the sessions are
put in SERVICE_DENIED state. The sessions are deleted after 2 minutes by the timer.

Usage Guidelines
The local proxy ARP feature allows the MSFC to respond to ARP requests for IP addresses within a
subnet where normally no routing is required. With the local proxy ARP feature enabled, the MSFC
responds to all ARP requests for IP addresses within the subnet and forwards all traffic between hosts in
the subnet. Use this feature only on subnets where hosts are intentionally prevented from communicating
directly to the Catalyst 6500 series switch on which they are connected.
ICMP redirects are disabled on interfaces where the local proxy ARP feature is enabled.

Modification
12.1(11b)E
Support for this command was introduced on the MSFC.
Usage Guidelines
If you do not enable the triggered RPF check, PIM periodically polls the routing tables for changes (set
using the ip multicast rpf interval command). When you enable the triggered RPF check, PIM polls the
routing tables when a change in the routing tables occurs. The min argument sets the initial backoff time.
Once triggered, PIM waits for additional routing table changes. If the min period expires without further
routing table changes, PIM scans for routing changes. If additional routing changes occur during the
backoff period, PIM doubles the length of the backoff period. You can set the maximum interval for the
doubled backoff period with the max argument.
Use this command in the following situation:
•
You have frequent route changes in your router (for example, on a dial-in router).
•
You want to either reduce the maximum RPF-check interval (for faster availability of IP multicast
on newly established routes).
•
You want to increase the RPF-check interval to reduce the CPU load that is introduced by the RPF
check.

Usage Guidelines
Note
Unicast RPF provides three basic modes:
•
Exists-only mode—A source address needs only to be present in the FIB and reachable through a
“real” interface; this situation also applies to the ip verify unicast source reachable-via any
allow-default command. The exists-only mode requires that a resolved and reachable source
address is present in the FIB table. The source address must be reachable through a configured
interface.
•
Any mode—The source must be reachable through any of the paths. For example, the source has
per-destination load balancing.
•
Rx mode—A source address must be reachable on the arrived interface. For example, the source
must be reachable without load balancing.
Unicast RPF is an input function and is applied only on the input interface of a router at the upstream
end of a connection.

ip verify unicast source reachable-via
To use Unicast RPF, enable CEF switching or dCEF switching in the router. You do not need to configure
the input interface for CEF switching. As long as CEF is running on the router, you can configure
individual interfaces with other switching modes.
Note
Unicast RPF will not work without CEF.
Do not use Unicast RPF on interfaces that are internal to the network. Internal interfaces are likely to
have routing asymmetry, which means that there are multiple routes to the source of a packet. You should
apply Unicast RPF only where there is natural or configured symmetry.

The ip wccp service redirect in command allows you to configure WCCP redirection on an interface
receiving inbound network traffic. When the command is applied to an interface, all packets arriving at
that interface will be compared against the criteria that is defined by the specified WCCP service. If the
packets match the criteria, they will be redirected.
The ip wccp service redirect out command allows you to configure the WCCP redirection check at an
outbound interface.
Caution
Note
Be careful not to confuse the ip wccp service redirect {out | in} interface configuration command with
the ip wccp redirect exclude in interface configuration command.
This command has the potential to affect the ip wccp redirect exclude in command. (These
commands have opposite functions.) If you have ip wccp redirect exclude in set on an interface and
you subsequently configure the ip wccp service redirect in command, the ip wccp redirect
exclude in command will be overridden. The opposite is also true: Configuring the ip wccp
redirect exclude in command will override the ip wccp service redirect in command.

Description
arpa
For Ethernet interfaces only—Use Novell’s Ethernet_II encapsulation.
This encapsulation is recommended for networks that handle both TCP/IP
and IPX traffic.
hdlc
For Serial interfaces only—Use HDLC encapsulation.
novell-ether
For Ethernet interfaces only—Use Novell’s “Ethernet_802.3”
encapsulation. This encapsulation consists of a standard 802.3 Media
Access Control (MAC) header followed directly by the IPX header with a
checksum of FFFF. It is the default encapsulation used by all versions of
NetWare up to and including Version 3.11.
novell-fddi
For FDDI interfaces only—Use Novell’s “FDDI_RAW” encapsulation.
This encapsulation consists of a standard FDDI MAC header followed
directly by the IPX header with a checksum of 0xFFFF.

•
For Ethernet interfaces—Use Novell’s Ethernet_802.2
encapsulation.This encapsulation consists of a standard 802.3 MAC
header followed by an 802.2 LLC header. This is the default
encapsulation used by NetWare Version 3.12 and 4.0.
•
For Token Ring interfaces—This encapsulation consists of a standard
802.5 MAC header followed by an 802.2 LLC header.
•
For FDDI interfaces—This encapsulation consists of a standard FDDI
MAC header followed by an 802.2 LLC header.
•
For Ethernet interfaces—Use Novell Ethernet_Snap encapsulation.
This encapsulation consists of a standard 802.3 MAC header followed
by an 802.2 SNAP LLC header.
•
For Token Ring and FDDI interfaces—This encapsulation consists of
a standard 802.5 or FDDI MAC header followed by an 802.2 SNAP
LLC header.
The ipx network command allows you to configure a single logical network on a physical network or
more than one logical network on the same physical network (network cable segment). Each network on
a given interface must have a different encapsulation type.
Note
You cannot configure more than 200 IPX interfaces on a router using the ipx network
command.
The first network you configure on an interface is considered to be the primary network. Any additional
networks are considered to be secondary networks; these must include the secondary keyword.
Note
In future Cisco IOS software releases, primary and secondary networks may not be
supported.
NLSP does not support secondary networks. You must use subinterfaces in order to use multiple
encapsulations with NLSP.

Catalyst 6500 Series Switch MSFC Commands
ipx network
Note
When enabling NLSP and configuring multiple encapsulations on the same physical LAN
interface, you must use subinterfaces. You cannot use secondary networks.
You can configure an IPX network on any supported interface as long as all the networks on the same
physical interface use a distinct encapsulation type. For example, you can configure up to four IPX
networks on a single Ethernet cable because Ethernet supports four encapsulation types.
The interface processes only packets with the correct encapsulation and the correct network number. IPX
networks using other encapsulations can be present on the physical network. The only effect on the
router is that it uses some processing time to examine packets to determine whether they have the correct
encapsulation.
All logical networks on an interface share the same set of configuration parameters. For example, if you
change the IPX RIP update time on an interface, you change it for all networks on that interface.
When you define multiple logical networks on the same physical network, IPX treats each encapsulation
as if it were a separate physical network. This means, for example, that IPX sends RIP updates and SAP
updates for each logical network.
The ipx network command is useful when migrating from one type of encapsulation to another. If you
are using it for this purpose, you should define the new encapsulation on the primary network.
To delete all networks on an interface, use the following command:
no ipx network
Deleting the primary network with the following command also deletes all networks on that interface.
The argument number is the number of the primary network.
no ipx network number
To delete a secondary network on an interface, use one of the following commands. The argument
number is the number of a secondary network.
no ipx network number
no ipx network number encapsulation encapsulation-type
Novell’s FDDI_RAW encapsulation is common in bridged or switched environments that connect
Ethernet-based Novell end hosts via a FDDI backbone. Packets with FDDI_RAW encapsulation are
classified as Novell packets, and are not automatically bridged when you enable both bridging and IPX
routing. Additionally, you cannot configure FDDI_RAW encapsulation on an interface configured for
IPX autonomous or SSE switching. Similarly, you cannot enable IPX autonomous or SSE switching on
an interface configured with FDDI_RAW encapsulation.
With FDDI_RAW encapsulation, platforms that do not use CBUS architecture support fast switching.
Platforms using CBUS architecture support only process switching of novell-fddi packets received on
an FDDI interface.

Support for this command was extended to the E train. This command was
change to support the ODM-based ACL merge function on both security
ACLs and ACLs used for QoS filtering.
Usage Guidelines
The BDD-based ACL merge function uses a method of representing Boolean functions to condense entries
into a single merged list of TCAM entries that can be programmed into the TCAM.
The ODM-based ACL merge function uses an order-dependent merge algorithm to process entries that can
be programmed into the TCAM.
Note
In Cisco IOS Release12.2(14)SX, the bdd option is supported on systems configured with a Supervisor
Engine 1 or a Supervisor Engine 2. The bdd option is not supported on systems configured with a
Supervisor Engine 3.
Note
In releases earlier than Cisco IOS Release 12.1(12c)E1, the ODM-based ACL merge function supports
only security ACLs and does not apply to ACLs used for QoS filtering. In Cisco IOS Release
12.1(12c)E1 and later releases, the ODM-based ACL merge function supports both security ACLs and
ACLs used for QoS filtering.
If you change the algorithm method, the change is not retroactive. For example, ACLs that have had the
merge applied are not affected. The merge change applies to future merges only.
Use the show fm summary command to see the status of the current merge method.

Support for this command was extended to the E train.
The mls ip cef rate-limit command is supported on systems configured with the Supervisor Engine 2
only.
Certain denial-of-service attacks target the route processing engines of routers. Certain packets that
cannot be forwarded by the PFC2 are directed to the MSFC2 for processing. Denial-of-service attacks
can overload the route processing engine and cause routing instability when running dynamic routing
protocols. The mls ip cef rate-limit command can be used to limit the amount of traffic sent to the
MSFC2 to prevent denial-of-service attacks against the route processing engine.
This command rate limits all CEF-punted data packets including the following:
•
Data packets going to the local interface IP address
•
Data packets requiring ARP
Setting the rate to a low value could impact handling of packets destined to the IP addresses of the local
interfaces and packets requiring ARP.
You should use this command to limit these packets to a normal rate and to avoid abnormal incoming
rates.

Support for this command was introduced on the MSFC.
Usage Guidelines
When you enable the ACL-based method of filtering RPF failures by entering the mls ip multicast stub
command on the redundant router, the following ACLs automatically download to the PFC and are
applied to the interface that you specify:
•
access-list 100 permit ip A.B.C.0 0.0.0.255 any
•
access-list 100 permit ip A.B.D.0 0.0.0.255 any
•
access-list 100 permit ip any 224.0.0.0 0.0.0.255
•
access-list 100 permit ip any 224.0.1.0 0.0.0.255
•
access-list 100 deny ip any 224.0.0.0 15.255.255.255
The ACLs filter RPF failures and drop them in hardware so that they are not forwarded to the router.
Use the ACL-based method of filtering RPF failures only in sparse-mode stub networks where there are
no downstream routers. For dense mode groups, RPF failure packets have to be seen on the router for
the PIM assert mechanism to function properly. Use CEF-or NetFlow-based rate limiting to rate limit
RPF failures in dense-mode networks and sparse-mode transit networks.

Changing the MTU value with the mtu command can affect values for the protocol-specific versions of
the command (for example, the ip mtu command). If the values specified with the ip mtu command is
the same as the value specified with the mtu command, and you change the value for the mtu command,
the ip mtu value automatically matches the new mtu command value. However, changing the values for
the ip mtu command has no effect on the value for the mtu command.

Support for this command was introduced on the MSFC.
Usage Guidelines
(Optional) Displays all of the flow information.
If you can configure a VACL on the port before you configure CBAC, the status displayed is INACTIVE;
otherwise, it is ACTIVE. If PFC resources are exhausted, the command displays BRIDGE followed by
the number of failed currently active NetFlow requests that have been sent to the MSFC2 for processing.
The show fm insp command output includes this information:
•
interface:—Interface on which the IP inspect feature is enabled.
•
(direction)—Direction in which the IP inspect feature is enabled (IN or OUT).
•
acl name:—Name used to identify the packets that are being inspected.
•
status:—(ACTIVE or INACTIVE) tells you if HW-assist is provided for this interface+direction
(ACTIVE=hardware assisted or INACTIVE).
The detail option also displays the ACEs that are part of the ACL that is used for IP inspect on the given
interface direction.
Examples
This example shows how to display the list and status of CBAC-configured ACLs and ports:
Router> show fm insp

Modification
12.1(11b)E
Support for this command was introduced on the Catalyst 6500 series switches.
Usage Guidelines
For additional notification types, refer to Cisco IOS documentation.
SNMP notifications can be sent as traps or inform requests. This command enables both traps and inform
requests for the specified notification types. To specify whether the notifications should be sent as traps
or informs, use the snmp-server host [traps | informs] command.
If you do not enter an snmp-server enable traps command, no notifications controlled by this command
are sent. In order to configure the router to send these SNMP notifications, you must enter at least one
snmp-server enable traps command. If you enter the command with no keywords, all notification types
are enabled. If you enter the command with a keyword, only the notification type related to that keyword
is enabled. In order to enable multiple types of notifications, you must issue a separate
snmp-server enable traps command for each notification type and notification option.
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 notifications. In order
to send notifications, you must configure at least one snmp-server host command.

Modification
12.1(13)E
Support for this command was introduced on the MSFC.
Usage Guidelines
The minimum delay period applies to all subsequent interface events.
The delay period applies only to the first interface-up event after the router has reloaded.
If the active router fails or is removed from the network, the standby router automatically becomes the
new active router. If the former active router comes back online, you can control whether it takes over
as the active router by using the standby preempt command.
However, even if the standby preempt command is not configured, the former active router resumes the
active role after it reloads and comes back online. Use the standby delay minimum reload command
to set a delay period for HSRP group initialization. This command allows time for the packets to get
through before the router resumes the active role.
We recommend that you use the standby delay minimum reload command if the standby timers
command is configured in milliseconds or if HSRP is configured on a VLAN interface of a switch.
In most configurations, the default values provide sufficient time for the packets to get through and it is
not necessary to configure longer delay values.
The delay is canceled if an HSRP packet is received on an interface.

Modification
12.1E
Support for this command was introduced on the MSFC.
Usage Guidelines
The standby ip command activates HSRP on the configured interface. If an IP address is specified, that
address is used as the designated address for the Hot Standby group. If no IP address is specified, the
designated address is learned through the standby function. For HSRP to elect a designated router, at
least one router on the cable must have been configured with, or have learned, the designated address.
Configuring the designated address on the active router always overrides a designated address that is
currently in use.
When the standby ip command is enabled on an interface, the handling of proxy ARP requests is
changed (unless proxy ARP was disabled). If the Hot Standby state of the interface is active, proxy ARP
requests are answered using the MAC address of the Hot Standby group. If the interface is in a different
state, proxy ARP responses are suppressed.
When group number 0 is used, no group number is written to NVRAM, providing backward
compatibility.

standby ip
To assist in troubleshooting, configure the group-number to match the VLAN number.
Increase the priority of at least one interface in the HSRP group. The interface with the highest priority
becomes active for that HSRP group.
All interfaces in the HSRP group should use the same timer values.
All interfaces in the HSRP group should use the same authentication string.
The alt keyword is used to specify an alternate configuration and is used in the following:
[no] standby [group-number] ip [ip-address [secondary]] alt [no] standby [group-number] ip
[ip-address [secondary]]
[no] standby [group-number] priority priority [preempt [delay delay]] alt [no] standby
[group-number] priority priority [preempt [delay delay]]
For additional information, see the “alt Keyword Usage” section on page 2-9.
Examples
This example shows how to enable HSRP for group 1 on an interface. The IP address used by the Hot
Standby group will be learned using HSRP.

This command was changed to include the designated-router option.
Usage Guidelines
This command is supported on systems configured with an MSFC2 only. This command is not supported
on systems configured with an MSFC1.
Prior to entering the designated-router option, you must ensure that the new designated router has a
higher HSRP priority than the current designated router to take over.
When a tracked interface goes down, the Hot Standby priority decreases by the number specified by the
priority-decrement argument. If an interface is not tracked, its state changes do not affect the Hot
Standby priority. For each interface configured for Hot Standby, you can configure a separate list of
interfaces to be tracked.

Catalyst 6500 Series Switch MSFC Commands
standby track
When multiple tracked interfaces are down, the decrements are cumulative whether they are configured
with priority-decrement values or not.
A tracked interface is considered down if the IP address is disabled on that interface.
You must enter the group-number when using the no form of this command.
If you configure HSRP to track an interface, and that interface is physically removed as in the case of an
OIR operation, then HSRP regards the interface as always down. You cannot remove the HSRP interface
tracking configuration. To prevent this situation, use the no standby track interface-type
interface-number command before you physically remove the interface.
When you enter a group-number 0, no group number is written to NVRAM, providing backward
compatibility.
Examples
This example shows how to enable HSRP tracking for group 1 on an interface:
Router(config-if)# standby 1 track Ethernet0/2
Router(config-if)#
This example shows how to specify that if the designated router becomes nondesignated, the active
HSRP router becomes the designated router:
Router(config-if)# standby 1 track designated-router 15

Catalyst 6500 Series Switch MSFC Commands
upgrade rom-monitor
Note
Releases 12.1(8a)EX and earlier do not support the field-upgradable ROMMON feature on a Supervisor
Engine 2. If you revert to a release prior to 12.1(8a)EX on a Supervisor Engine 2, the previously
upgraded ROMMON will be invalidated and returned to run the ROMMON stored on the PROM. If you
wish to use releases prior to 12.1(8a)EX on a Supervisor Engine 2, but upgrade your ROMMON, you
must physically replace a ROMMON PROM with a ROMMON PROM that is programmed with the new
ROMMON image. Contact Cisco TAC for additional information.
The slot num is required for this command to function properly.
The sp keyword is not supported.
You can enter the upgrade rom-monitor rp {invalidate | preference} {region1 | region2} command to
manually set the execution preference on a ROMMON in region1 or region2. This command is entered in
EXEC privileged mode only.
You can enter the upgrade rom-monitor rp file {device:filename} command to program a new
ROMMON into a FLASH (region1 or region2) region.
Examples
This example shows how to program the new ROMMON into the MSFC2 ROMMON flash file:
Router# upgrade rom-monitor rp file bootflash:FUR_173.srec
ROMMON image upgrade in progress
Erasing flash
Programming flash
Verifying new image
ROMMON image upgrade complete, MSFC2 must be reloaded.
