Chapter 1 Command-Line InterfaceUnderstanding Command ModesUnderstanding Command ModesThe Catalyst 6500 series switch Cisco IOS user interface is divided into many different modes. The commands that are available to you depend on which mode you are currently in. You can obtain a list of commands that are available for each command mode by entering a question mark (?) at the system prompt.
When you start a session on the Catalyst 6500 series switch, you begin in user mode, often called EXEC mode. Only a limited subset of the commands are available in EXEC mode. In order to have access to all commands, you must enter privileged EXEC mode. Normally, you must enter a password to enter privileged EXEC mode. From privileged EXEC mode, you can enter any EXEC command or enter global configuration mode. Most EXEC commands are one-time commands, such as show commands, which show the current status of a given item, and clear commands, which clear counters or interfaces. The EXEC commands are not saved across reboots of the Catalyst 6500 series switch.The configuration modes allow you to make changes to the running configuration. If you later save the configuration, these commands are stored across Catalyst 6500 series switch reboots. In order to get to the various configuration modes, you must start at global configuration mode where you can enter interface configuration mode, subinterface configuration mode, and a variety of protocol-specific modes.ROM-monitor mode is a separate mode that is used when the Catalyst 6500 series switch cannot boot properly. If your Catalyst 6500 series switch or access server does not find a valid system image when it is booting, or if its configuration file is corrupted at startup, the system might enter ROM-monitor mode. Table 1-3 provides a summary of the main command modes.

Chapter 1 Command-Line InterfaceUsing the No and Default Forms of CommandsFor more information on command modes, refer to the Using the Command Line Interface chapter of the Configuration Fundamentals Configuration Guide.
Note Prior to Cisco IOS Release 12.1(11b)E, you could issue EXEC-level commands (such as show, clear, and debug commands) in EXEC mode only. In Cisco IOS Release 12.1(11b)E or later, you can issue EXEC-level Cisco IOS commands (such as show, clear, and debug commands) from within global configuration mode or other modes by issuing the do command followed by the EXEC command. See the do command for information on how to use this command.
Using the No and Default Forms of CommandsAlmost 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 arguments that are set to certain default values. In these cases, the default form of the command enables the command and sets arguments 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.
Subinterface configuration
From interface configuration mode, specify a subinterface with an interface command.
Router(config-subif)# To exit to global configuration mode, enter the exit command.To enter privileged EXEC mode, enter the end command or press Ctrl-Z.
ROM monitor From privileged EXEC mode, enter the reload EXEC command. Press the Break key during the first 60 seconds while the system is booting.
Rommon> To exit ROM-monitor mode, you must reload the image by entering the boot command. If you use the boot command without specifying a file or any other boot instructions, the system boots from the default Flash image (the first image in onboard Flash memory). Otherwise, you can instruct the system to boot from a specific Flash image (using the boot system flash filename command).

Chapter 1 Command-Line InterfaceUsing the CLI String SearchUsing the CLI String SearchThe 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) that 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 ExpressionsA 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.
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 1-4 lists the keyboard characters with special meaning.
Table 1-4 Characters with Special Meaning
Character 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.1-7Catalyst 6500 Series Switch Cisco IOS Command ReferenceRelease 12.1 E
78-14058-05
Chapter 1 Command-Line InterfaceUsing the CLI String SearchTo 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\-\]] 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]
^ 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.

78-14058-05
Chapter 1 Command-Line InterfaceUsing the CLI String SearchMultiple-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 expressiona.
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 expressiona\. 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 1-5 lists the special characters that specify multiples of a regular expression.
This example matches any number of occurrences of the letter a, including none:a*
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 (*):\**
Table 1-5 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.1-9Catalyst 6500 Series Switch Cisco IOS Command ReferenceRelease 12.1 E
78-14058-05
Chapter 1 Command-Line InterfaceUsing the CLI String SearchTo 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.
AlternationAlternation allows you to specify alternative patterns to match against a string. You separate the alternative patterns with a vertical bar or pipe (|). 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.
AnchoringYou 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 1-6.
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] 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.
Table 1-6 Special Characters Used for Anchoring
Character Description
^ Matches the beginning of the string. $ Matches the end of the string.1-10Catalyst 6500 Series Switch Cisco IOS Command ReferenceRelease 12.1 E
78-14058-05
Chapter 1 Command-Line InterfaceSaving Configuration ChangesFor example: _1300_ matches any string that has 1300 somewhere in the string. The strings 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 RecallAs shown in the Multipliers section on page 1-9, 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, and 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.
Saving Configuration ChangesTo 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-configBuilding configuration...
It might take a minute or two to save the configuration. After the configuration has been saved, the following output appears:[OK]Router#
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.1-11Catalyst 6500 Series Switch Cisco IOS Command ReferenceRelease 12.1 E

Chapter 2 Cisco IOS Commands for the Catalyst 6500 Series SwitchesactionThe redirect action supports interface lists instead of single interfaces as shown in the following example:
[...] {redirect {{ethernet | fastethernet | gigabitethernet | tengigabitethernet} slot/port} | {port-channel channel-id}}
The action clause specifies the action to be taken when a match occurs. The number of valid values for port-channel number depends on the software release. For releases prior to Release 12.1(3a)E3, valid values are from 1 to 256; for Releases 12.1(3a)E3, 12.1(3a)E4, and 12.1(4)E1, valid values are from 1 to 64. Release 12.1(5c)EX and later support a maximum of 64 values ranging from 1 to 256. Release 12.1(13)E and later support a maximum of 64 values ranging from 1 to 282; values 257 to 282 are supported on the CSM and FWSM only.The forwarded packets are subject to any applied Cisco IOS ACLs. The capture action sets the capture bit in VACL-forwarded packets. Ports with the capture function enabled can receive VACL-forwarded packets that have the capture bit set. Only VACL-forwarded packets that have the capture bit set can be captured. The log option is supported on Supervisor Engine 2 only. When the log option is specified, dropped packets are logged in software. Only dropped IP packets can be logged. The redirect option allows you to specify up to five interfaces, which can be physical interfaces or EtherChannels. An EtherChannel member is not allowed to be a redirect interface.The log and redirect keywords are not supported for VACLs on WAN interfaces.The action clause in a VACL can be forward, drop, capture, or redirect. Traffic can also be logged. VACLs applied to WAN interfaces do not support the redirect or log actions.For systems with a Supervisor Engine 1, the redirect interface must be in the redirected packets source VLAN.
For systems with a Supervisor Engine 2, the redirect interface must be in the VLAN for which the VACL map is configured. In a VLAN access map, if at least one ACL is configured for a packet type (IP, IPX, or MAC), the default action for the packet type is drop (deny).If an ACL is not configured for a packet type, the default action for the packet type is forward (permit). If an ACL for a packet type is configured and the ACL is empty or undefined, the configured action will be applied to the packet type.
Examples This example shows how to define a drop and log action: Router(config-access-map)# action drop log Router(config-access-map)#
This example shows how to define a forward action: Router(config-access-map)# action forward Router(config-access-map)#

Use the no form of this command to remove the specification.
boot config {device:file-name}no boot config
Syntax Description
Defaults The configuration file is located in NVRAM.
Command Modes Global configuration
Command History
Usage Guidelines The configuration file must be an ASCII file located in the specified file system.disk0: is a Class C file system.bootflash:, slot0:, slot1:, and sup-bootflash: are Class A file systems.For Class A Flash file systems, the CONFIG_FILE environment variable specifies the file system and filename of the configuration file to use for initialization (startup). You set the CONFIG_FILE environment variable in the current running memory when you use the boot config command. This variable specifies the configuration file used for initialization (startup). When you use the boot config command, you affect only the running configuration. You must save the environment variable setting to your startup configuration to place the information under ROM monitor control and to have the environment variable function as expected. Use the copy system:running-config nvram:startup-config command to save the environment variable from your running configuration to your startup configuration.The software displays an error message and does not update the CONFIG_FILE environment variable in the following situations:
You specify nvram: as the file system, and it contains only a distilled version of the configuration. (A distilled configuration does not contain access lists.)
You specify a configuration file in the filename argument that does not exist or is not valid.
device: Device identification; valid values are bootflash:, const_nvram:, flash:, nvram:, slot0:, sup-bootflash:, or disk0:.

78-14058-05
Chapter 2 Cisco IOS Commands for the Catalyst 6500 Series Switchesboot configDuring initialization, the NVRAM configuration is used when the CONFIG_FILE environment variable does not exist or when it is null (such as at a first-time startup). If the software detects a problem with NVRAM or the configuration it contains, the device enters setup mode. When you use the no form of this command, the NVRAM configuration is used as the startup configuration.
You can view the contents of the BOOT, BOOTLDR, and the CONFIG_FILE environment variables using the show bootvar command. This command displays the settings for these variables as they exist in the startup configuration as well as in the running configuration if a running configuration setting differs from a startup configuration setting.The disk0: keyword is supported only on systems configured with a Supervisor Engine 2.
Examples This example shows how to set the configuration file located in the internal Flash memory to configure itself during initialization. The third line copies the specification to the startup configuration, ensuring that this specification takes effect upon the next reload.Router (config)# boot config flash:router-configRouter (config)# endRouter# copy system:running-config nvram:startup-configRouter#

cd [filesystem:][directory]
Syntax Description
Defaults Initial default file system is slot0:.
Command Modes EXEC
Command History
Usage Guidelines For all EXEC commands that have an optional filesystem argument, the system uses the file system specified by the cd command when you omit the optional filesystem argument. For example, the dir command, which displays a list of files on a file system, contain an optional filesystem argument. When you omit this argument, the system lists the files on the file system specified by the cd command.If you do not specify a directory on a file system, the default is the root directory on that file system.The disk0: keyword is supported only on systems configured with a Supervisor Engine 2.
Examples This example sets the default file system to the Flash PC card inserted in slot 0:Router# cd slot0:Router# pwdslot0:/
filesystem: (Optional) URL, alias of the directory, or file system followed by a colon; valid values are bootflash:, const_nvram:, flash:, nvram:, slot0:, sup-bootflash:, sup-image:, sup-slot0:, or disk0:.

Chapter 2 Cisco IOS Commands for the Catalyst 6500 Series Switcheschannel-groupUsage Guidelines The number of valid values for the channel-group number depends on the software release. For releases prior to Release 12.1(3a)E3, valid values are from 1 to 256; for Releases 12.1(3a)E3, 12.1(3a)E4, and 12.1(4)E1, valid values are from 1 to 64. Release 12.1(5c)EX and later support a maximum of 64 values ranging from 1 to 256. Release 12.1(13)E and later support a maximum of 64 values ranging from 1 to 282; values 257 to 282 are supported on the CSM and FWSM only.The channel group number is global and is shared between all the channeling protocols. If a specific channel number is used for the PAgP-enabled interfaces of a channel group, that same channel number cannot be used for configuring a channel that has LACP-enabled interfaces or vice versa.Entering the auto or desirable keyword enables PAgP on the specified interface; the command will be rejected if it is issued on an LACP-enabled interface.The active and passive keywords are valid on PAgP-disabled interfaces only.You can change the mode for an interface only if it is the only interface designated to the specified channel group. The on keyword forces the bundling of the interface on the channel without any negotiation.You can manually configure a switch with PAgP on one side and LACP on the other side in the on mode. With the on mode, a usable EtherChannel exists only when a port group in on mode is connected to another port group in on mode. If you enter this command on an interface that is added to a channel with a different protocol (than the protocol you are entering), the command is rejected. If the interface belongs to a channel, the no form of this command is rejected.All ports in an EtherChannel must use the same protocol; you cannot run two protocols on one module. PAgP and LACP are not compatible; both ends of a channel must use the same protocol. You can change the protocol at any time, but this change causes all existing EtherChannels to reset to the default channel mode for the new protocol. Configure all ports in an EtherChannel to operate at the same speed and duplex mode (full duplex only for LACP mode).On systems configured with nonfabric-enabled modules and fabric-enabled modules, you can bundle ports across all modules, but those bundles cannot include a DFC-equipped module port.You do not have to create a port channel interface before assigning a physical interface to a channel group. A port channel interface is created automatically when the channel group gets its first physical interface, if it is not already created.You do not have to disable the IP address that is assigned to a physical interface that is part of a channel group, but it is highly recommended.You can create both Layer 2 and Layer 3 port channels by entering the interface port-channel command or when the channel group gets its first physical interface assignment. The port channels are not created at runtime or dynamically.Any configuration or attribute changes you make to the port channel interface are propagated to all interfaces within the same channel group as the port channel (for example, configuration changes are also propagated to the physical interfaces that are not part of the port channel but are part of the channel group).
Caution Do not enable Layer 3 addresses on the physical EtherChannel interfaces. Assigning bridge groups on the physical EtherChannel interfaces causes loops in your network. 2-16Catalyst 6500 Series Switch Cisco IOS Command ReferenceRelease 12.1 E
