ATM Module Command Reference

You access the ATM module by creating a session with it. To open a session with the ATM module, use the session mod_num command from the Console> prompt. After you enter this command, the switch responds with the Enter Password prompt. Enter atm as the default password. At this point, you are at the ATM#> prompt, and you have direct access to only the ATM module that you have established a session with.

Once you are connected to the ATM module, a subset of the Internetwork Operating System (IOS) commands normally available for Cisco routers is available for configuring it. Some of these commands have been slightly modified to accommodate the differences specific to the ATM module in the Catalyst 5000 series switch.

The IOS commands for the Catalyst 5000 series switch ATM module are divided into the following categories:

ATM Module User Interface Commands

This section describes the commands used to enter and exit the various Cisco Internetwork Operating System (Cisco IOS) configuration command modes. It provides a description of the help command and help features, lists the command editing keys and functions, and details the command history feature.

You can abbreviate the syntax of Cisco IOS configuration commands. The ATM module recognizes a command when you enter enough characters of the command to uniquely identify it.

For user interface task information and examples, see the "Administrative Interfaces" chapter.

disable

Usage Guidelines

Table 7-1 provides a description of the keys used to enter and edit commands. Ctrl indicates the Control key. It must be pressed simultaneously with its associated letter key. Esc indicates the Escape key. It must be pressed first, followed by its associated letter key. Keys are not case sensitive.

Table 7-1 : Editing Keys and Functions

Keys Function

Tab Completes a partial command name entry. When you enter a unique set of characters and press the Tab key, the system completes the command name. If you enter a set of characters that could indicate more than one command, the system beeps to indicate an error. Enter a question mark (?) immediately following the partial command (no space). The system provides a list of commands that begin with that string.

Delete or Backspace Erases the character to the left of the cursor.

Return At the command line, pressing the Return key processes a command. At the "---More---" prompt on a terminal screen, pressing the Return key scrolls down a line.

Spacebar Allows you to see more output on the terminal screen. Press the Spacebar when you see "---More---" on the screen to display the next screen.

Left Arrow¹ Moves the cursor one character to the left. When you enter a command that extends beyond a single line, you can press the Left Arrow key repeatedly to scroll back toward the system prompt and verify the beginning of the command entry.

Right Arrow¹ Moves the cursor one character to the right.

Up Arrow¹ or Ctrl-P Recalls commands in the history buffer, beginning with the most recent command. Repeat the key sequence to recall successively older commands.

Down Arrow¹ or
Ctrl-N Return to more recent commands in the history buffer after recalling commands with the Up Arrow or Ctrl-P. Repeat the key sequence to recall successively more recent commands.

Ctrl-A Moves the cursor to the beginning of the line.

Ctrl-B Moves the cursor back one character.

Ctrl-D Deletes the character at the cursor.

Ctrl-E Moves the cursor to the end of the command line.

Ctrl-F Moves the cursor forward one character.

Ctrl-K Deletes all characters from the cursor to the end of the command line.

Ctrl-L or Ctrl-R Redisplays the system prompt and command line.

Ctrl-T Transposes the character to the left of the cursor with the character located at the cursor.

Ctrl-U or Ctrl-X Deletes all characters from the cursor back to the beginning of the command line.

Ctrl-V or Esc Q Inserts a code to indicate to the system that the keystroke immediately following should be treated as a command entry, not as an editing key.

Ctrl-W Deletes the word to the left of the cursor.

Ctrl-Y Recalls the most recent entry in the delete buffer. The delete buffer contains the last ten items you have deleted or cut. Ctrl-Y can be used in conjunction with Esc Y.

Ctrl-Z Ends configuration mode and returns you to the EXEC prompt.

Esc B Moves the cursor back one word.

Esc C Capitalizes from the cursor to the end of the word.

Esc D Deletes from the cursor to the end of the word.

Esc F Moves the cursor forward one word.

Esc L Changes to lowercase from the cursor to the end of the word.

Esc U Capitalizes from the cursor to the end of the word.

Esc Y Recalls the next buffer entry. The buffer contains the last ten items you have deleted. Press Ctrl-Y first to recall the most recent entry. Then press Esc Y up to nine times to recall the remaining entries in the buffer. If you bypass an entry, continue to press Esc Y to cycle back to it.

Use the enable EXEC command to enter privileged EXEC mode.

enable

Syntax Description

This command has no arguments or keywords.

Command Mode

EXEC

Usage Guidelines

Because many of the privileged commands set operating parameters, privileged access should be password-protected to prevent unauthorized use. If the system administrator has set a password with the enable password global configuration command, you are prompted to enter it before being allowed access to privileged EXEC mode. The password is case sensitive. The factory default password on the ATM module is atm.

Example

In the following example, the user enters the enable command and is prompted to enter a password. The password is not displayed on the screen. After entering the password, the system enters privileged command mode as indicated by the pound sign (#).

ATM> enable
Password:
ATM#

Related Commands

help

help

Use the help command to display a brief description of the help system.

help

Syntax Description

This command has no arguments or keywords.

Command Mode

Available in all command modes

Usage Guidelines

The help command provides a brief description of the context-sensitive help system.

To list all commands available for a particular command mode, enter a question mark (?) at the system prompt.
To obtain a list of commands that begin with a particular character string, enter the abbreviated command entry immediately followed by a question mark (?). This form of help is called word help, because it lists only the keywords or arguments that begin with the abbreviation you entered.
To list a command's associated keywords or arguments, enter a question mark (?) in place of a keyword or argument on the command line. This form of help is called command syntax help, because it lists the keywords or arguments that apply based on the command, keywords, and arguments you have already entered.

Examples

Enter the help command for a brief description of the help system:

ATM# help
Help may be requested at any point in a command by entering
a question mark '?'. If nothing matches, the help list will
be empty and you must backup until entering a '?' shows the
available options.
Two styles of help are provided:
1. Full help is available when you are ready to enter a
   command argument (e.g. 'show ?') and describes each possible
   argument.
2. Partial help is provided when an abbreviated argument is entered
   and you want to know what arguments match the input
   (e.g. 'show pr?'.)

The following example shows how to use word help to display all the privileged EXEC commands that begin with the letters ¨co¨:

ATM# co?
configure  connect  copy

history

Use the history line configuration command to enable the command history function, or to change the command history buffer size for a particular line. To disable the command history feature, use the no form of this command.

history [size number-of-lines]
no history [size number-of-lines]

Syntax Description

size number-of-lines (Optional) Specifies the number of command lines that the system will record in its history buffer. The range is 0 to 256.

Default

10 lines

Command Mode

Line configuration

Usage Guidelines

The history command, without the size keyword and the number-of-lines argument, enables the history function with the last buffer size specified or with the default of 10 lines, if there was not a prior setting.

The no history command, without the size keyword and the number-of lines argument, disables the history feature but remembers the buffer size if it was something other than the default. The no history size command resets the buffer size to 10.

The command history feature provides a record of EXEC commands you have entered. This feature is particularly useful for recalling long or complex commands or entries, including access lists.

Table 7-2 lists the keys and functions you can use to recall commands from the command history buffer.

Table 7-2 : History Keys

Key Function

Up Arrow or Ctrl-P ¹ Recalls commands in the history buffer in a backward sequence, beginning with the most recent command. Repeat the key sequence to recall successively older commands.

Down Arrow or Ctrl-N¹ Returns to more recent commands in the history buffer after recalling commands with the Up Arrow or Ctrl-P . Repeat the key sequence to recall successively more recent commands.

¹ The arrow keys function only with ANSI-compatible terminals such as VT100s.

Key	Function
Up Arrow or Ctrl-P ¹	Recalls commands in the history buffer in a backward sequence, beginning with the most recent command. Repeat the key sequence to recall successively older commands.
Down Arrow or Ctrl-N¹	Returns to more recent commands in the history buffer after recalling commands with the Up Arrow or Ctrl-P . Repeat the key sequence to recall successively more recent commands.

Example

In the following example, virtual terminal line 4 is configured with a history buffer size of 35 lines:

Configuration Commands

This section describes the commands available to configure Flash memory on the ATM module.

reload

Use the reload EXEC command to reload the operating system.

reload

Syntax Description

This command has no arguments or keywords.

Command Type

IOS Cnfiguration command.

Command Mode

EXEC

Usage Guidelines

The reload command halts the ATM module. If the ATM module is set to restart on error, it reboots itself. Use the reload command after configuration information is entered into a file and saved to the startup configuration.

You cannot reload from a virtual terminal if the system is not set up for automatic booting. This prevents the system from dropping to the ROM monitor and thereby taking the system out of the remote user's control.

If you modify your configuration file, the system prompts you to save the configuration. During a save operation, the system asks you if you want to proceed with the save if the CONFIG_FILE environment variable points to a startup configuration file that no longer exists. If you say "yes" in this situation, the system goes to setup mode upon reload.

Example

The following example illustrates how to enter the reload command at the privileged EXEC prompt:

ATM>reload

show version

Use the show version EXEC command to display the configuration of the system hardware, the software version, the names and sources of configuration files, and the boot images.

show version

LAN Emulation Commands

This section describes the commands available to configure a LAN client on the ATM interface for LAN emulation (LANE). For ATM LANE configuration information and examples, refer to the chapter entitled "Configuring the ATM Module."

Because some LANE commands are used often and others are used very rarely, the command descriptions in this chapter identify the commands you are most likely to use. Look under "Usage Guidelines" for the indicator This command is ordinarily used.

lane client

Use the lane client interface configuration command to activate a LANE client on the specified subinterface. To remove a previously activated LANE client on the subinterface, use the no form of this command.

lane client ethernet vlan# [elan-name]
no lane client [ethernet vlan# [elan-name]]

Syntax Description

ethernet Identifies the type of emulated LAN attached to this subinterface.

elan-name (Optional) Name of the emulated LAN. This argument is optional because the client obtains its emulated LAN name from the configuration server. Maximum length is 32 characters.

vlan# Identifies the number of the vlan that corresponds to the specified emulated LAN.

Default

None

Command Type

IOS LAN emulation command.

Command Mode

Interface configuration

Usage Guidelines

This command is ordinarily used.

If a lane client command has already been entered on the subinterface for a different emulated LAN, then the client initiates termination procedures for that emulated LAN and joins the new emulated LAN.

If you do not provide an elan-name value, the client contacts the server to find which emulated LAN to join. If you do provide an emulated LAN name, the client consults the configuration server to ensure that no conflicting bindings exist.

Example

In the following example, the LANE client is activated for VLAN 3 called eng:

ATM(config-if)# lane client ethernet vlan 3 eng

Related Command

lane client-atm-address

lane client-atm-address

Use the lane client-atm-address interface configuration command to specify an ATM address, and thus override the automatic ATM address assignment, for the LANE client on the specified subinterface. To remove the ATM address previously specified for the LANE client on the specified subinterface and thus revert to the automatic address assignment, use the no form of this command.

lane client-atm-address atm-address-template
no client-atm-address [atm-address-template]

Syntax Description

atm-address-template ATM address or a template in which wildcard characters are replaced by any nibble or group of nibbles of the prefix bytes, the ESI bytes, or the selector byte of the automatically assigned ATM address.

Default

Automatic ATM address assignment.

Command Type

IOS LAN emulation command.

Command Mode

Interface configuration

Usage Guidelines

Use of this command on a selected subinterface, but with a different ATM address than was used previously, replaces the LANE client's ATM address.

ATM Addresses. A LANE ATM address has the same syntax as an NSAP (but it is not a network-level address):

A 13-byte prefix that includes the following fields defined by the ATM Forum: AFI (Authority and Format Identifier) field (1 byte), DCC (Data Country Code) or ICD (International Code Designator) field (2 bytes), DFI field (Domain Specific Part Format Identifier) (1 byte), Administrative Authority field (3 bytes), Reserved field (2 bytes), Routing Domain field (2 bytes), and Area field (2 bytes).
A 6-byte end-system identifier (ESI)
A 1-byte selector field

Address Templates. LANE ATM address templates can use two types of wildcards: an asterisk (*) to match any single character, and an ellipsis (...) to match any number of leading or trailing characters. The values of the characters replaced by widlcards come from the automatically assigned ATM address.

In LANE, a prefix template explicitly matches the ATM address prefix but uses wildcards for the ESI and selector fields. An ESI template explicitly matches the ESI field but uses wildcards for the prefix and selector.

In Cisco's implementation of LANE, the prefix corresponds to the switch, the ESI corresponds to the ATM interface, and the Selector field corresponds to the specific subinterface of the interface.

For a discussion of Cisco's method of automatically assigning ATM addresses, refer to the "Configuring LAN Emulation" chapter in the Router Products Configuration Guide.

Examples

The following example uses an ESI template to specify the part of the ATM address corresponding to the interface; the remaining parts of the ATM address come from automatic assignment:

ATM(config-if)# lane client-atm-address...0800.200C.1001.**

The following example uses a prefix template to specify the part of the ATM address corresponding to the switch; the remaining parts of the ATM address come from automatic assignment:

ATM(config-if)# lane client-atm-address 47.000014155551212f.00.00...

Related Command

lane client

lane config-atm-address

Use the lane config-atm-address interface configuration command to specify a given configuration server's ATM address. To remove an assigned ATM address, use the no form of this command.

lane config-atm-address atm-address-template
no lane config-atm-address [atm-address-template]

Syntax Description

Default

No specific ATM address or method is set.

Command Type

IOS LAN emulation command.

Command Mode

Interface configuration

Usage Guidelines

This command causes the LANE client on the subinterface to use the specified ATM address (rather than the ATM address provided by the ILMI) to locate the configuration server.

ATM Addresses. A LANE ATM address has the same syntax as an NSAP (but it is not a network-level address):

A 13-byte prefix that includes the following fields defined by the ATM Forum: AFI (Authority and Format Identifier) field (1 byte), DCC (Data Country Code) or ICD (International Code Designator) field (2 bytes), DFI field (Domain Specific Part Format Identifier) (1 byte), Administrative Authority field (3 bytes), Reserved field (2 bytes), Routing Domain field (2 bytes), and Area field (2 bytes).
A 6-byte end-system identifier (ESI)
A 1-byte selector field

Address Templates. LANE ATM address templates can use two types of wildcards: an asterisk (*) to match any single character, and an ellipsis (...) to match any number of leading or trailing characters. The values of the characters replaced by wildcards come from the automatically assigned ATM address.

In Cisco's implementation of LANE, the prefix corresponds to the switch, the ESI corresponds to the ATM interface, and the Selector field corresponds to the specific subinterface of the interface.

For a discussion of Cisco's method of automatically assigning ATM addresses, refer to the "Configuring the ATM Module" chapter.

Example

The following example specifies the LANE configuration server's ATM address:

ATM(config-subif)#lane config-atm-address 39.000000000000014155551211.0800200c1001.00

lane le-arp

Use the lane le-arp interface configuration command to add a static entry to the LE ARP table of the LANE client configured on the specified subinterface. To remove a static entry from the LE ARP table of the LANE client on the specified subinterface, use the no form of this command.

lane le-arp mac-address atm-address
no lane le-arp mac-address atm-address

Syntax Description

mac-address MAC address to bind to the specified ATM address.

atm-address ATM address.

Default

No static address bindings are provided.

Command Type

IOS LAN emulation command.

Command Mode

Interface configuration

Usage Guidelines

This command only adds or removes a static entry binding a MAC address to an ATM address. It does not add or remove dynamic entries. Removing the static entry for a specified ATM address from an LE ARP table does not release Data Direct VCCs established to that ATM address. However, clearing a static entry clears any fast-cache entries that were created from the MAC address-to-ATM address binding.

Static LE ARP entries are not aged and are not removed automatically.

To remove dynamic entries from the LE ARP table of the LANE client on the specified subinterface, use the clear lane le-arp command.

Example

The following command adds a static entry to the LE ARP table:

ATM(config-if)# lane le-arp 0800.aa00.0101 47.000014155551212f.00.00.0800.200C.1001.01

lane pvc

Use the lane pvc interface configuration command to associate an ATM address, and optionally a LANE client ID, with a PVC previously created on the specified subinterface. To remove a prior entry, use the no form of this command.

lane pvc vcd atm-address (for LANE client configuration)
no lane pvc vcd [atm-address [lec-id]]

Syntax Description

vcd Virtual channel descriptor that identifies the PVC.

atm-address ATM address of the LANE component at the other end of the PVC.

lec-id (Not used when the command is used to configure a LANE client; required when the command is used to configure a LANE server) Number in the range 1 to 65279 that uniquely identifies the LANE client connected to this PVC.

Defaults

No PVC is created. No virtual channel descriptor (VCD), ATM address, and LANE client ID are provided for PVCs.

Command Type

IOS LAN emulation command.

Command Mode

Interface configuration

Usage Guidelines

Ordinarily, switched virtual circuits (SVCs) are used instead of PVCs for communication within emulated LANs, and unique LANE client IDs are assigned dynamically by the LANE server. This command is used only when PVCs are used.

Use this command to configure a LANE client when PVCs are used instead of SVCs for Data Direct circuits between LANE clients; this command identifies the ATM address of the LANE client at the other end of the virtual circuit. In this case, do not use the lec-id argument.

To create the PVC, use the atm pvc command. The vcd value in the lane pvc command must match a vcd value in an atm pvc command.

Use of the lane pvc command on a LANE client and the lane register command on a LANE server enable the use of PVCs, instead of SVCs alone, for LANE.

If you use PVCs for the Control Direct VCCs, you must also use PVCs for the Control Distribute VCCs. If you use PVCs for the Multicast Send VCCs, you must also use PVCs for the Multicast Forward VCCs.

Example

The following example associates an ATM address with PVC 100:

ATM(config-subif)#lane pvc 100 55.005500550055005500550055.00000C0425C2.00

Related Commands

lane register

lane register

Use the lane register interface configuration command to register a LANE client that is connected by PVC to the LANE server on the specified subinterface. To remove a prior entry, use the no form of this command.

lane register vcd mac-address atm-address
no lane register vcd [mac-address atm-address]

Syntax Description

vcd Virtual channel descriptor of the Server Direct PVC through which the LANE client is connected to the LANE server.

mac-address MAC address of the LANE client.

atm-address ATM address of the LANE client.

Defaults

No PVC is defined. No MAC address and ATM address are provided.

Command Type

IOS LAN emulation command.

Command Mode

Interface configuration

Usage Guidelines

Ordinarily, SVCs are used instead of PVCs for communications within emulated LANs, and registration occurs dynamically via the LANE protocol. This command is used only when PVCs are used.

When PVCs are used instead of SVCs for Server Direct circuits between the LANE server and LANE clients, use this command on the LANE server to identify the MAC address and the ATM address of the LANE client at the other end of a virtual circuit. If the client at the other end has a different ATM address, it is not allowed to join the emulated LAN. This can function as a security check.

Use the lane pvc command on a LANE client and the lane register command on a LANE server to enable use of PVCs, instead of SVCs alone, for LANE. The vcd value in the lane register command must match the vcd value in a lane pvc command and in an atm pvc command.

If you use PVCs for the Control Direct VCCs, you must also use PVCs for the Control Distribute VCCs. If you use PVCs for the Multicast Send VCCs, you must also use PVCs for the Multicast Forward VCCs
