This chapter describes the Catalyst 5000 series switch command-line interface (CLI), the Asychronous Transfer Mode (ATM) module CLI, and the Route Switch Module (RSM) CLI, which are used to configure and maintain Catalyst 5000 series switch supervisor engine and switching modules. For descriptions of all switch CLI, ATM and RSM module CLI commands, refer to the Catalyst 5000 Series Command Reference publication. For additional information on IOS commands, refer to the Configuration Fundamentals Command Reference publication.
The Catalyst 5000 series switch CLI is a basic command-line interpreter, similar to the UNIX C shell, that provides command-line editing, history substitution, and the creation of aliases.
You can access the CLI from a console terminal connected to an EIA/TIA-232 port or through a Telnet session. Telnet sessions are automatically disconnected after remaining idle for a configurable time period.
To access the switch through the EIA/TIA-232 port, perform these steps:
After accessing the switch through the console port (EIA/TIA-232), you see this display:
Cisco Systems Console
Enter password:
Console>
Console>
Console> quit
To use Telnet, you must first set the Internet Protocol (IP) address for the switch. Refer to "Configuring the Supervisor Software," for information about setting the IP address. You can conduct multiple sessions through Telnet.
To access the switch from a remote host with Telnet, perform these steps:
After connecting through a Telnet session, you see this display:
%telnet catalyst1Trying 123.236.273.11...Connected to catalyst1.Escape character is '^]'.Cisco Systems Console Fri Mar 10 1995, 17:50:45Enter password:Sorry. Try again. Enter password:Console>Console>Console>quitConnection closed by foreign host.%
This section describes how to access the command modes and operate the switch CLI.
There are two modes of operation, both password protected: normal and privileged. Enter normal-mode commands for everyday system monitoring. Enter privileged commands for system configuration and basic troubleshooting.
After you log in, the system automatically enters normal mode, which gives you access to normal-mode commands only. You can enter privileged mode by entering the enable command followed by a second password. To return to normal mode, enter the disable command at the prompt.
The following sample session shows how to enable privileged mode:
Cisco Systems Console Fri Mar 10 1995, 17:50:45 Enter password: Console> Console> Console> enable Enter Password: Console> (enable)
The switch administration command sets are not case-sensitive. In addition, commands and parameters can be abbreviated as long as they contain enough letters to be unique with reference to the other commands or parameters at that level.
| Command | Function |
|---|---|
| Ctrl -W | Deletes last word typed. |
| Ctrl -U | Deletes entire line. |
| Ctrl -C | Escapes and terminates prompts and lengthy tasks. |
| Delete key or backspace key | Erases mistake when entering a command; reenter command after using this key. |
Commands that you enter during each terminal session are stored in a history buffer. Commands in the history buffer can be repeated or edited in a style similar to using the UNIX C shell. The history buffer stores the last 20 commands entered during a terminal session.
To repeat a recent command:
!! - repeat the most recent command !-nn - repeat the nnth most recent command !nn - repeat command nn !aaa - repeat the command beginning with string aaa !?aaa - repeat the command containing the string aaa
To modify and repeat the most recent command:
^aaa^bbb - replace the string aaa with the string bbb in the most recent command
To add a string to the end of a previous command and repeat it:
!!aaa - add string aaa to the end of the most recent command !nn aaa - add string aaa to the end of command nn !aaa bbb - add string bbb to the end of the command beginning with string aaa !?aaa bbb - add string bbb to the end of the command containing the string aaa
Context-sensitive help for commands is provided. Enter help or ? in normal or privileged mode to see a listing of the commands available in those modes. On selected commands, entering help or ? after a command provides additional information. In general, command usage, the help menu, and, when appropriate, parameter ranges are provided if you enter a command using the wrong number of arguments or inappropriate arguments.
The ? command allows you to display usage and syntax information about a specific command or to list groups of commands. In normal mode, enter the ? command to display a list of top-level commands, as follows:
Console> ?
Commands:
----------------------------------------------------------------------
enable Enable privileged mode

The Catalyst 5000 series switch is a multimodule system. Commands you enter from the CLI can apply to the entire system or to a specific module, port, or virtual LAN (VLAN).
Catalyst 5000 series module slots, ports, and VLANs are numbered starting with 1. The supervisor engine module is module 1, residing in the top slot. If you have a Catalyst 5500 switch with a redundant supervisor engine, the supervisor modules reside in slots 1 and 2. On each module, port 1 is the left-most port. To reference a specific port on a specific module, the command syntax is mod_num/port_num. For example, 3/1 denotes module 3, port 1. In some commands, such as set trunk, set cam, and set vlan commands, you can enter lists of ports and VLANs.
To designate ports, enter the module and port number pairs, separated by commas. To specify a range of ports, use a hyphen (-) between the module number and port number pairs. Hyphens take precedence over commas. The following examples show several ways of designating ports:
Example 1. 2/1,2/3 denotes module 2, port 1 and module 2, port 3.
Example 2. 2/1-12 denotes module 2, ports 1 through 12.
Example 3. 2/1-2/12 is the same as Example 2.
Each VLAN is designated by a single number. You specify lists of VLANs the same way you do for ports. Individual VLANs are separated by commas (,); ranges are separated by hyphens (-). In the following example, VLAN numbers 1 through 10 and VLAN 1000 are specified:
1-10,1000
Some commands require a Media Access Control (MAC) address, IP address, or IP alias, which must be designated in a standard format. The MAC address format must be six hexadecimal numbers separated by hyphens, as shown in the following example:
00-00-0c-24-d2-fe
The IP address format is 32 bits, written as 4 octets separated by periods (dotted decimal format) that are made up of a network section, an optional subnet section, and a host section, as shown in the following example:
126.2.54.1
If the IP alias table is configured, you can use IP aliases in place of the dotted decimal IP address. This is true for most commands that use an IP address, except for commands that define the IP address or IP alias. For more information about the set interface and set ip alias commands, refer to the Catalyst 5000 Series Command Reference publication.
The ATM module uses a subset of the Cisco IOS software. The Cisco IOS user interface provides access to several different command modes. Each command mode provides a group of related commands. This section describes how to use the ATM module CLI to access and list the commands available in each command mode and explains the primary uses for each command mode.
For security purposes, Cisco IOS software provides two command access modes: user EXEC and privileged EXEC. The user EXEC mode does not require a password, and allows you direct access only to the ATM module with which you have established a session. The commands available in user EXEC mode are a subset of the commands available in privileged EXEC mode.
The privileged EXEC mode requires a password (the default password is atm). From the privileged level, you can access the six configuration modes: user EXEC, privileged EXEC, global configuration, interface configuration, line configuration, and LAN Emulation (LANE) database configuration. Entering a question mark (?) at the system prompt displays a list of commands available for each command mode.
Almost every configuration command also has a no form. In general, enter the no form to disable a feature or function. Enter the command without the keyword no to reenable a disabled feature or to enable a feature that is disabled by default. Refer to the Catalyst 5000 Series Command Reference publication for more information about the ATM module commands.
The user interface also provides context-sensitive help on command syntax. The section "Getting Context-Sensitive Help" (later in this chapter) describes how to use the help system. It also describes the command editing and command history features that enable you to recall previous command entries and easily edit command entries.
To access an ATM module installed in a Catalyst 5000 series switch, enter the session mod_num command at the Console> prompt. The switch responds with the Enter Password prompt. Enter atm as the default password. The ATM module responds with the ATM> prompt. At this point, you are in user EXEC command mode, and you have direct access only to the ATM module with which you have established a session.
The following example shows how to open a session on an ATM module:
Console>session mod_num Console> Enter Password: Console>atmATM>
This section describes the command modes and functions that allow you to access and operate the ATM module CLI.
Table 2-1 lists the command modes, how to access each mode, the prompt you see while you are in that mode, the main uses for each configuration mode, and the method to exit that mode. The prompts listed assume the default name ATM.
After you log in to the ATM module, you are automatically in user EXEC command mode. The user EXEC commands are a subset of the privileged EXEC commands. The user EXEC commands allow you to change terminal settings on a temporary basis, perform basic tests, and list system information.
To list the user EXEC commands, complete this task:
| Task | Command |
|---|---|
| List the user EXEC commands. | ? |
The user-level prompt is as follows:
ATM>
To list the commands available in user EXEC mode, enter a question mark (?) at the ATM> prompt, as shown in the following example:
ATM> ? Exec commands: connect Open a terminal connection disable Turn off privileged commands disconnect Disconnect an existing network connection enable Turn on privileged commands exit Exit from the EXEC help Description of the interactive help system lock Lock the terminal login Log in as a particular user logout Exit from the EXEC name-connection Name an existing network connection ping Send echo messages resume Resume an active network connection show Show running system information systat Display information about terminal lines telnet Open a telnet connection terminal Set terminal line parameters traceroute Trace route to destination tunnel Open a tunnel connection where List active connection ATM>
Because many privileged commands set operating parameters, use password protection to restrict access to privileged EXEC mode. The privileged EXEC command set includes those commands contained in user EXEC mode, as well as the configure command through which you can access the remaining command modes. Privileged EXEC mode also includes high-level testing commands, such as debug.
To access and list the privileged EXEC commands, complete these steps:
| Task | Command |
|---|---|
| Step 1 Enter the privileged EXEC mode. | enable password |
| Step 2 List privileged EXEC commands. | ? |
If the system administrator has set a password, you are prompted to enter it before being allowed access to privileged EXEC mode. The password is not displayed on the screen and is case-sensitive. If an enable password has not been set, you can only access privileged EXEC mode from the console. The default password for the ATM module is atm.
The following example shows how to access privileged EXEC mode and list privileged EXEC commands:
ATM> enable Password: ATM# ? Exec commands: clear Reset functions clock Manage the system clock configure Enter configuration mode connect Open a terminal connection copy Copy a config file to or from a tftp server debug Debugging functions (see also 'undebug') disable Turn off privileged commands disconnect Disconnect an existing network connection enable Turn on privileged commands exit Exit from the EXEC help Description of the interactive help system lock Lock the terminal login Log in as a particular user logout Exit from the EXEC name-connection Name an existing network connection no Disable debugging functions ping Send echo messages reload Halt and perform a cold restart resume Resume an active network connection rsh Execute a remote command send Send a message to other tty lines setup Run the SETUP command facility show Show running system information systat Display information about terminal lines telnet Open a telnet connection terminal Set terminal line parameters test Test subsystems, memory, and interfaces traceroute Trace route to destination tunnel Open a tunnel connection undebug Disable debugging functions (see also 'debug') where List active connections write Write running configuration to memory, network, or terminal ATM#
From the privileged EXEC mode, you can access global configuration mode. For instructions, see the following section "Accessing Global Configuration Mode."
To return from privileged EXEC mode to user EXEC mode, perform this task:
| Task | Command |
|---|---|
| Go from privileged EXEC mode to user EXEC mode. | disable |
Global configuration commands apply to features that affect the ATM module as a whole. To enter global configuration mode, enter the configure privileged EXEC command. When you enter this command, the privileged EXEC mode prompts you for the source of the configuration commands, as follows:
Configuring from terminal, memory, or network [terminal]?
You can then specify either the terminal, nonvolatile random-access memory (NVRAM), or a file stored on a network server as the source of configuration commands (see the "System Image, Microcode Image, and Configuration File Load Commands" chapter in the Router Products Command Reference publication). The default is to enter commands from the console terminal. Pressing Return begins this configuration method.
To access and list the global configuration commands, complete these steps:
| Task | Command |
|---|---|
| Step 1 At the console terminal, from the privileged EXEC mode, enter global configuration mode. | configure |
| Step 2 List the global configuration commands. | ? |
The following example shows how to access global configuration mode and list global configuration commands:
ATM# configure terminal Enter configuration commands, one per line. End with CNTL/Z. ATM(config)# ? Configure commands: aaa Authentication, Authorization and Accounting. access-list Add an access list entry alias Create command alias arp Set a static ARP entry async-bootp Modify system bootp parameters banner Define a login banner boot Modify system boot parameters buffers Adjust system buffer pool parameters clock Configure time-of-day clock config-register Define the configuration register downward-compatible config Generate a configuration compatible with older software default-value Default character-bits values dnsix-dmdp Provide DMDP service for DNSIX dnsix-nat Provide DNSIX service for audit trails enable Modify enable password parameters end Exit from configure mode exit Exit from configure mode help Description of the interactive help system hostname Set system's network name interface Select an interface to configure ip Global IP configuration subcommands lane Configure LAN Emulation line Configure a terminal line logging Modify message logging facilities map-class Configure static map class map-list Configure static map list priority-list Build a priority list privilege Command privilege parameters queue-list Build a custom queue list scheduler Scheduler parameters service Modify use of network based services snmp-server Modify SNMP parameters tacacs-server Modify TACACS query parameters tftp-server Provide TFTP service for netload requests username Establish User Name Authentication
To exit global configuration command mode and return to privileged EXEC mode, enter one of these commands:
| Task | Command |
|---|---|
| Exit global configuration mode. | exit end Ctrl-Z |
Interface configuration commands modify the operation of the ATM interface. Interface configuration commands always follow an interface global configuration command, which defines the interface type.
To access and list the interface configuration commands, complete these steps:
| Task | Command |
|---|---|
| Step 1 From global configuration mode, enter interface configuration mode. | interface type-number1 |
| Step 2 List the interface configuration commands. | ? |
The following example shows how to access interface configuration mode and list interface configuration commands to configure ATM interface 0:
ATM(config)# interface atm 0 ATM(config-if)# ? Interface configuration commands: arp Set arp type (arpa, probe, snap) or timeout asig ATM Signalling Interface Subcommands atm Modify ATM parameters backup Modify dial-backup parameters bandwidth Set bandwidth informational parameter custom-queue-list Assign a custom queue list to an interface delay Specify interface throughput delay description Interface specific description exit Exit from interface configuration mode Fair-queue Enable Fair Queuing on an Interface help Description of the interactive help system hold-queue Set hold queue depth ip Interface Internet Protocol config commands keepalive Enable keepalive lane Modify LANE parameters load-interval Specify interval for load calculation for an interface loopback Configure internal loopback on an interface map-group Configure static map group mtu Set the interface Maximum Transmission Unit (MTU) no Negate a command or set its defaults priority-group Assign a priority group to an interface shutdown Shutdown the selected interface snmp Modify SNMP interface parameters sscop SSCOP Interface Subcommands transmit-interface Assign a transmit interface to a receive-only interface tx-queue-limit Configure card level transmit queue limit ATM(config-if)#
To exit interface configuration mode and return to global configuration mode, enter the following command:
| Task | Command |
|---|---|
| Exit interface configuration mode. | exit |
To exit global configuration mode and return to privileged EXEC mode, enter one of the following commands:
| Task | Command |
|---|---|
| Exit global configuration mode. | end Ctrl-Z |
Line configuration commands modify the operation of a terminal line. Line configuration commands always follow a line command, which defines a line number. These commands change terminal parameter settings either on a line-by-line basis or for a range of lines.
To access and list the virtual terminal line configuration commands, complete these steps:
| Task | Command |
|---|---|
| Step 1 From global configuration mode, configure a virtual terminal line. | line {vty} line-number [ending-line-number]1 |
| Step 2 List the line configuration commands. | ? |
The following example shows how to enter line configuration mode for virtual terminal line 4 and list the line configuration commands. The ATM (config-line)# prompt indicates line configuration mode:
ATM(config)# line 0 4 ATM(config-line)# ? Line configuration commands: access-class Filter connections based on an IP access list autocommand Automatically execute an EXEC command ata-character-bits Size of characters being handled databits Set number of data bits per character editing Enable command line editing escape-character Change the current line's escape character exec Start an EXEC process exec-banner Enable the display of the EXEC banner exec-character-bits Size of characters to the command exec exec-timeout Set the EXEC timeout exit Exit from line configuration mode flowcontrol Set the flow control full-help Provide help to unprivileged user help Description of the interactive help system history Enable and control the command history function ip IP options length Set number of lines on a screen location Enter terminal location description logging Modify message logging facilities login Enable password checking modem Configure the Modem Control Lines monitor Copy debug output to the current terminal line no Negate a command or set its defaults notify Inform users of output from concurrent sessions padding Set padding for a specified output character parity Set terminal parity password Set a password privilege Change privilege level for line refuse-message Define a refuse banner rotary Add line to a rotary group rxspeed Set the receive speed session-timeout Set interval when there is no input traffic special-character bits Size of the escape (and other special) characters speed Set the transmit and receive speeds start-character Define the start character stop-character Define the stop character stopbits Set async line stop bits terminal-type Set the terminal type transport Define transport protocols for line txspeed Set the transmit speeds vacant-message Define a vacant banner width Set width of the display terminal
To exit line configuration mode and return to global configuration mode, enter the following command:
| Task | Command |
|---|---|
| Exit line configuration mode. | exit |
To exit global configuration mode and return to privileged EXEC mode, enter one of the following commands:
| Task | Command |
|---|---|
| Exit global configuration mode. | end Ctrl-Z |
This section describes the following functions that are performed by the ATM module:
The previous sections described the first level of help available with the user interface. Entering a question mark (?) at the system prompt displays the commands for each command mode. You can also get a list of any command's associated keywords and arguments with the context-sensitive help feature.
To get help specific to a command mode, a command, a keyword, or arguments, perform one of these tasks:
| Task | Command |
|---|---|
| Obtain a brief description of the help system in any command mode. | help |
| Configure a line or lines to receive help for the full set of user-level commands when you enter ?. | full-help |
| Configure a line to receive help for the full set of user-level commands for this EXEC session. | terminal full-help1 |
| Obtain a list of commands that begin with a particular character string. | abbreviated-command-entry? |
| Complete a partial command name. | abbreviated-command-entry<Tab> |
| List all commands available for a particular command mode. | ? |
| List a command's associated keywords. | command ? |
| List a keyword's associated arguments. | command keyword ? |
When using context-sensitive help, the space (or lack of a space) before the question mark (?) is significant.
To obtain a list of commands that begin with a particular character sequence, enter the form of help called word help. Type in characters followed immediately by the question mark (?). Do not include a space. This form of help completes the word for you.
To list keywords or arguments, enter the form of help called command syntax help. Enter a question mark (?) in place of a keyword or argument. Include a space before the ?. This form of help reminds you which keywords or arguments are applicable based on the command, keywords, and arguments you have already entered.
You can abbreviate commands and keywords by using a number of characters that allow a unique abbreviation. For example, you can abbreviate the show command to sh.
Enter the help command (which is available in any command mode) for a brief description of the help system:
ATM#helpHelp may be requested at any point in a command by enteringa question mark '?'. If nothing matches, the help list willbe empty and you must back up until entering a '?' shows theavailable options.Two styles of help are provided:1. Full help is available when you are ready to enter acommand argument (e.g. 'show ?') and describes each possibleargument.2. Partial help is provided when an abbreviated argument is enteredand you want to know what arguments match the input(e.g. 'show pr?'.)
You can enter a partial command name and a question mark (?) to obtain a list of commands beginning with a particular character set. See "Completing a Partial Command Name" later in this chapter for more detail.
The following example illustrates how context-sensitive help enables you to create an access list from configuration mode. Enter the letters co at the system prompt followed by a question mark (?). Do not leave a space between the last letter and the question mark (?). The system provides the commands that begin with co.
ATM# co?
configure connect copy
Enter the configure command followed by a space and a question mark (?) to list the command's keywords and a brief explanation:
ATM# configure ?
memory Configure from NV memory
network Configure from a TFTP network host
terminal Configure from the terminal
<cr>
An error indicator (^) symbol appears at the point in the command string where you have entered an incorrect command, keyword, or argument. The error location indicator and interactive help system allow you to easily find and correct syntax errors.
In the following example, suppose you want to clear a virtual circuit. First, use context-sensitive help to check the syntax for the command.
ATM# clear ? access-list Clear access list statistical information arp-cache Clear the entire ARP cache atm-vc Clear ATM virtual circuits on an interface counters Clear counters on one or all interfaces host Delete host table entries interface Clear the hardware logic on an interface ip IP lane lane line Reset a terminal line
The help output shows that the atm-vc keyword is required. Next, check the syntax for specifying the type of virtual circuit:
ATM# clear atm-vc ? ATM ATM interface
Enter the type of virtual circuit:
ATM# clear atm-vc atm 0 % Incomplete command.
The system indicates that you need to provide additional arguments to complete the command. Press Ctrl-P (see the next section, "Using the Command History Features") to automatically repeat the previous command entry. Then add a space and question mark (?) to reveal the additional arguments:
ATM# clear atm-vc atm 0 ? <1-4095> Virtual Circuit Number (VCD)
Now you can complete the command entry:
ATM# clear atm-vc atm 0 4096
^
% Invalid input detected at '^' marker.
The caret symbol (^) and help response indicate an error at 6. To list the correct syntax, enter the command up to the point where the error occurred, and then enter a question mark (?):
ATM# clear atm-vc atm 0 ? <1-4095> Virtual Circuit Number (VCD)
Enter the year using the correct syntax, and press Return to execute the command.
ATM# clear atm-vc atm 0 11
The command history feature keeps a record of commands you have entered and allows you to recall these commands. The functions of the command history feature are as follows:
| Task | Command |
|---|---|
| Enable the command history feature for the current terminal session. | terminal history [size number-of-lines]1 |
| Task | Command |
|---|---|
| Enable the command history feature. | history [size number-of-lines]1 |
| Task | Key Sequence/Command |
|---|---|
| Recall commands in the history buffer, beginning with the most recent command. Repeat the key sequence to recall successively older commands. | Press Ctrl-P or the up arrow key.1 |
| Return to more recent commands in the history buffer after recalling commands with Ctrl-P or the up arrow key. Repeat the key sequence to recall successively more recent commands. | Press Ctrl-N or the down arrow key.1 |
| While in EXEC mode, list the last several commands you have just entered. | show history |
| Task | Command |
|---|---|
| Disable the command history feature for the current session. | terminal no history1 |
| Task | Command |
|---|---|
| Configure the line so that the command history feature is disabled. | no history |
Catalyst 5000 series software release 2.3 includes an enhanced editing mode that provides a set of editing key functions similar to those of the Emacs editor. You can enter commands in uppercase, lowercase, or a mix of both. Only passwords are case sensitive. You can abbreviate commands and keywords to the number of characters that allow a unique abbreviation.
For example, you can abbreviate the show command to sh. After entering the command at the system prompt, press Return to execute the command. The editing features are as follows:
| Task | Command |

The RSM is a fully-functional router running Cisco IOS software. The Cisco IOS user interface provides access to several different command modes. Each command mode provides a group of related commands.
For security purposes, Cisco IOS software provides two levels of access to commands: user and privileged. The unprivileged user mode is called user EXEC mode. The privileged mode is called privileged EXEC mode and requires a password. The commands available in user EXEC mode are a subset of the commands available in privileged EXEC mode.
From the privileged level, you can access global configuration mode and six specific configuration modes: interface, subinterface, line, router, ipx-router, and route-map configuration. Entering a question mark (?) at the system prompt displays a list of commands available for each command mode.
Almost every configuration command also has a no form. In general, enter the no form to disable a feature or function. Enter the command without the keyword no to reenable a disabled feature or to enable a feature that is disabled by default. Refer to the Catalyst 5000 Series Switch Route Switch Module Installation and Configuration Note, Catalyst 5000 Series Command Reference, and the Cisco IOS Configuration Fundamental Command Reference publications for more information about the RSM commands.
The user interface also provides context-sensitive help on command syntax. It also describes the command editing and command history features that enable you to recall previous command entries and easily edit command entries.
To access an RSM installed in a Catalyst 5000 series switch, enter the session mod_num command at the Console> prompt. The switch responds with the Enter Password prompt. Enter the password for the RSM. The RSM responds with the Router> prompt. At this point, you are in user EXEC command mode, and you have direct access only to the RSM with which you have established a session.
The following example shows how to open a session on an RSM:
Console>session mod_num Console> Enter Password:Router>
Refer to the Configuration Fundamentals Command Reference publication for router commands and how to use the CLI.
