atm pvc

Use the atm pvc command to create a PVC on the Catalyst 5000 series switch interface. The no form of this command deletes the specified PVC.

atm pvc vcd vpi vci [aal5snap | ilmi | qsaal]
no atm pvc vcd vpi vci

Note This version of the atm pvc command is available only in ATM software release 50.1(1) and later, ATM software release 51.1(1) and later.
atm pvc vcd vpi vci [aal5snap | ilmi | qsaal] [peak_rate average_rate [burst_size]]
   [
oam
seconds]
no atm pvc vcd vpi vci
Syntax Description

vcd Virtual circuit descriptor; a unique number for each Catalyst 5000 series switch that identifies which VPI/VCI to use for a particular packet.
vpi VPI for the PVC. The range of vpi is 0 to 255. The VPI value is unique only on a single interface, not throughout the ATM network.
vci VCI for the PVC. The range is from 0 to 65535. The VCI value is unique only on a single interface, not throughout the ATM network.
aal5snap (Optional) Keyword that specifies the use of AAL5 with LLC/SNAP encapsulation.
ilmi (Optional) Keyword that specifies the use of ILMI.
qsaal (Optional) Keyword that specifies signaling AAL.
peak_rate (Optional) Maximum rate (in kbps) at which this virtual circuit can transmit. The range is from 0 to 155000. Available in ATM PVC traffic-shaping software release 50.1(1) and later. The maximum rate for peak_rate in ATM PVC traffic-shaping software release 51.1(1) and later is 45000 kbps.
average_rate (Optional) Average rate (in kbps) at which this virtual circuit can transmit. The range is from 0 to 1000. Available in ATM PVC traffic-shaping software release 50.1(1) and later, and 51.1(1) and later.
burst_size (Optional) Burst cell size in number of cells. Acceptable values are 0 to 1. Available in ATM PVC traffic-shaping software release 50.1(1) and later, and software release 51.1(1) and later.
oam seconds (Optional) Keyword that specifies how often to generate an OAM 5 loopback cell from this virtual circuit. Available in ATM PVC traffic-shaping software release 50.1(1) and later, and software release 51.1(1) and later.
Default

If the peak_rate and average_rate options are omitted, the PVC defaults to the highest bandwidth rate queue available. By default, the VC is configured to run as fast as possible. If the oam keyword is omitted, OAM cells are not generated. If you use the oam keyword without specifying seconds, the default value of 10 seconds is used.

Command Type

Cisco IOS ATM command.

Command Mode

Interface configuration.

Usage Guidelines

The atm pvc command creates a PVC and attaches it to the VPI and VCI specified. You cannot specify both vpi and vci as 0.

If you are configuring an SVC, you must use this command to configure the PVC that handles the SVC call setup and termination. In this case, specify the qsaal keyword.

The peak_rate argument determines the size of the rate queue used. ATM PVC traffic-shaping software release 50.1(1) and later, and software release 51.1(1) and later dynamically create rate queues to satisfy the specifications of atm pvc commands. When an atm pvc command specifies a peak rate that does not match any use-configured rate queue, a rate queue is created dynamically.

The oam keyword causes the Catalyst 5000 series switch to generate and echo OAM F5 loopback cells, used to verify connectivity. Once OAM cell generation is enabled, OAM cells are transmitted periodically. The remote end must respond by echoing back the cells.

Examples

This example shows how to create a PVC to be used for ATM signaling for an SVC, using VPI 0 and VCI 5:

ATM(config-if)#atm pvc 1 0 5 qsaal

This example shows how to create a PVC in ATM PVC traffic-shaping software release 50.1, specifying the peak and average rates and OAM cell generation:

ATM(config-if)#atm pvc 1 0 5 aal5snap 155000 1000 oam

atm sonet

Use the atm sonet command to set the mode of operation and control type for cell-rate decoupling on the SONET PLIM. The no form of this command restores the default value.

atm sonet {stm-4 | sts-12c}
no atm sonet

Syntax Description
stm-4 Keyword that specifies synchronous transport module level 4 (STM-4) operation.
sts-12c Keyword that specifies synchronous transport signal level 12, concatenated (STS-12c) operation.
Default

The default is STS-12c operation.

Command Type

Cisco IOS ATM command.

Command Mode

Interface configuration.

Usage Guideline

This command applies only to the ATM dual PHY OC-12 module.

The no atm sonet stm-4 command is the same as the atm sonet sts-12c command.

Example

This example shows how to set the mode of operation to stm-4:

ATM (config-if)#atm sonet stm-4
ATM (config-if)# 

atm traffic-shape rate

Use the atm traffic-shape rate command to configure output throttling on your Catalyst 5000 series switch ATM module. The no form of the command returns the output rate to the default.

atm traffic-shape rate 1-155
no atm traffic-shape rate
Syntax Description
1-155 Number between 1 and 155 indicating Mbps.
Default

The default is 155 Mbps.

Command Type

Cisco IOS ATM command.

Command Mode

Interface configuration.

Usage Guideline

This command is not supported by the ATM dual PHY OC-12 module.

Example

This example shows how to set the output throttle to 50:

ATM(config)#int atm0
ATM(config-if)#atm traffic-shape rate 50
ATM(config-if)#end

atm uni-version

Use the atm uni-version command to specify the UNI version (3.0 or 3.1) the switch should use when ILMI link autodetermination is unsuccessful or ILMI is disabled. The no form of this command restores the version to the default.

atm uni-version version_num
no atm uni-version

Syntax Description
version_num UNI version for the interface. Valid values are 3.0 or 3.1.
Default

The default UNI version is 3.0.

Command Type

Cisco IOS ATM command.

Command Mode

Configuration.

Example

This example shows how to set the UNI version to 3.1:

ATM(config)#atm uni-version 3.1

atm vc-per-vp

Use the atm vc-per-vp command to set the maximum number of VCIs to support per VPI. The no form of this command restores the default value.

atm vc-per-vp num
no atm vc-per-vp

Syntax Description
num Maximum number of VCIs to support per VPI. Valid values are 32, 64, 128, 256, 512, and 1024.
Default

By default, the maximum number of VCIs to support per VPI is 1024.

Command Type

Cisco IOS ATM command.

Command Mode

Interface configuration.

Usage Guidelines

This command controls the memory allocation in the Catalyst 5000 series switch for the VCI table. It defines the maximum number of VCIs to support per VPI; it does not designate the VCI numbers.

An invalid VCI causes a warning message to display.

Example

This example shows how to set the maximum number of VCIs to support per VPI to 512:

ATM(config-if)#atm vc-per-vp 512

atmsig close

Use the atmsig close command to disconnect a particular SVC.

atmsig close atm0 vcd
Syntax Description
atm0 Keyword used to specify the atm0 interface number to close the SVC, because VCs are numbered per interface.
vcd Virtual circuit descriptor of the SVC to close.
Command Type

Cisco IOS ATM command.

Command Mode

EXEC.

Example

This example shows how to close SVC 2 on the ATM module:

ATM#atmsig close atm0 2

client-atm-address name

Use the client-atm-address name command to add a LANE address entry to the configuration server's database. The no form of this command removes a client address entry from the table.

client-atm-address atm-address-template name elan-name
no client-atm-address
atm-address-template
Syntax Description
atm-address-template Template that explicitly specifies an ATM address or a specific part of an ATM address and uses wildcard characters for other parts of the ATM address.

Wildcard characters can replace any nibble or group of nibbles in the prefix, the ESI, or the selector fields of the ATM address.

name elan-name Name of the ELAN. The maximum length of elan-name is 32 characters.
Default

By default, no address and no ELAN name are configured.

Command Mode

Database configuration.

Usage Guidelines

This command binds to the specified ELAN any client whose address matches the specified template. When a client comes up, it consults the LANE configuration server, which responds with the ATM address of the LANE server for the ELAN. The client then initiates join procedures with the LANE server.

You must create the ELAN specified by the elan-name argument using the name server-atm-address command before you use the client-atm-address command.

If an existing entry in the configuration server's database binds the LANE client ATM address to a different ELAN, the new command is rejected.

This command affects only the bindings in the named configuration server database. It has no effect on the LANE components themselves.

A LANE ATM address has the same syntax as a NSAP, but is not a network-level address:

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.

In LANE, a prefix template explicitly matches the 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 our implementation of LANE, the prefix corresponds to the specific subinterface of the interface.

Examples

This example uses an ESI template to specify the part of the ATM address corresponding to an interface. This template allows any client on any subinterface of the interface that corresponds to the displayed ESI value, no matter which switch the router is connected to, to join the engineering ELAN:

ATM(lane-config-database)#client-atm-address ...0800.200c.1001.** name engineering

This example uses a prefix template to specify the part of the ATM address corresponding to the switch. This template allows any client on the subinterface of any interface connected to the switch that corresponds to the displayed prefix to join the marketing ELAN:

ATM(lane-config-database)#client-atm-address 47.000014155551212f.00.00... name marketing
Related Commands

default-name
lane database
name server-atm-address

default-name

Use the default-name command to provide an ELAN name in the configuration server's database for those client MAC addresses and client ATM addresses that do not have explicit ELAN name bindings. Use the no form of this command to remove the default name.

default-name elan-name
no default name

Syntax Description
elan-name Default ELAN name for any LANE client MAC address or LANE client ATM address not explicitly bound to any ELAN name. The maximum length of elan-name is 32 characters.
Default

By default, no name is configured.

Command Type

Cisco IOS ATM command.

Command Mode

Database configuration.

Usage Guidelines

This command affects only the bindings in the configuration server's database. It has no effect on the LANE components themselves.

The named ELAN must already exist in the configuration server's database before this command is used. If the default name-to-ELAN name binding already exists, the new binding replaces it.

Table 11-1: Keys To Enter and Edit Commands
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 lists the commands that begin with that string.
Delete or Backspace Erases the character to the left of the cursor.
Return Processes a command when you are at the command line. 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 to 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 older commands.
Down Arrow1 or Ctrl-N 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 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 deleted or cut. Ctrl-Y can be used with Esc Y.
Ctrl-Z Ends configuration mode and returns 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 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, press Esc Y to cycle back to it.

1 The arrow keys function only with ANSI-compatible terminals such as VT100.

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 Type

Cisco IOS ATM command.

Command Mode

Available in all ATM command modes.

Usage Guidelines

To list all commands available for a particular command mode, enter a question mark (?) at the system prompt.

To obtain commands that begin with a particular character string, enter the abbreviated command entry and then 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 associated keywords or arguments for a command, 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

This example shows how to display 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?'.)

This example shows how to use word help to display the privileged EXEC commands that begin with the letters co:

ATM#co?
configure copy

history

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

history [size number-of-lines]
no history
Syntax Description
size (Optional) Keyword used to specify the number of command entries that the system records in its history buffer.
number-of-lines (Optional) Number of command line entries; valid values are 0 to 256.
Default

By default, number-of-lines is set to 10.

Command Type

Cisco IOS ATM command.

Command Mode

Line configuration.

Usage Guidelines

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

The history command enables the history function with the last buffer size specified or with the default of ten lines if there was no prior setting. The history size number-of-lines command sets the number of command entries stored in the command history buffer.

The no history command disables the history feature but remembers the buffer size if it was set to a value other than the default. The no history size command resets the buffer size to the default.

Table 11-2 lists the keys and functions you can use to recall commands from the command history buffer.


Table  11-2: History Keys
Key Function
Up Arrow or Ctrl-P1 Recalls commands in the history buffer in a backward sequence, beginning with the most recent command. Repeat the key sequence to recall 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 more recent commands.

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

This example shows how to configure virtual terminal line 4 with a history buffer size of 35 lines:

ATM#config terminal
Enter configuration commands, one per line. End with Ctrl-Z.
ATM(config)#line vty 4
ATM(config-line)#history size 35

Usage Guideline

If you do not specify the mul keyword when entering a subinterface number, the CLI does not accept the command.

Examples

This example shows how to enter interface configuration mode for interface atm0:

ATM(config)#interface atm0
ATM(config-if)#

This example shows how to enter subinterface configuration mode for subinterface atm0.1:

ATM(config-if)#interface atm0.1
ATM(config-subif)#

lane auto-config-atm-address

Use the lane auto-config-atm-address command to specify that the ATM address is computed automatically for the LECS or the LES and LEC, depending on whether the config keyword is used. To remove the previously assigned ATM address, use the no form of this command.

lane [config] auto-config-atm-address
no lane [config] auto-config-atm-address
Syntax Description
config (Optional) Keyword used to specify the LECS ATM address.
Default

By default, no specific ATM address or method is set.

Command Type

Cisco IOS ATM command.

Command Mode

Interface configuration.

Usage Guidelines

When the config keyword is not present, this command causes the LES and LEC on the subinterface to use the automatically assigned ATM address for the LECS.

When the config keyword is present, this command assigns the automatically generated ATM address to the LECS configured on the interface. Multiple commands that assign ATM addresses to the LECS can be issued on the same interface to assign different ATM addresses to the LECS. Commands that assign ATM addresses to the LECS include lane auto-config-atm-address, lane config-atm-address, and lane fixed-config-atm-address.

Example

This example shows how to associate the LECS with the database named network1 and how to specify that the LECS's ATM address is automatically assigned:

ATM(config-if)#lane config auto-config-atm-address
lane database network1
name eng server-atm-address 39.0000014155551211.0800.AA00.1001.02
name mkt server-atm-address 39.0000014155551211.0800.AA00.4001.01
lane config network1
lane auto-config-atm-address
ATM(config-if)#
Related Commands

lane client

Use the lane client 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_num [elan-name]
no lane client
[ethernet vlan_num [elan-name]]
Syntax Description
ethernet Keyword that indicates the type of ELAN attached to the interface.
vlan_num Number of the VLAN that corresponds to the specified ELAN.
elan-name (Optional) Name of the ELAN. This argument is optional because the client obtains its ELAN name from the configuration server. Maximum length for elan-name is 32 characters.
Default

None.

Command Type

Cisco IOS LANE command.

Command Mode

Interface configuration.

Usage Guidelines

If you already entered a lane client command on the subinterface for a different ELAN, the client initiates termination procedures for that ELAN and joins the new ELAN.

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

Example

This example shows how to activate the LANE client for a VLAN 3 called eng:

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

lane client-atm-address

lane client-atm-address

Use the lane client-atm-address command to specify an ATM address and to override 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 revert to 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

Cisco IOS LANE command.

Command Mode

Interface configuration.

Usage Guidelines

If you use this command on a selected subinterface, but with a different ATM address than was used previously, it replaces the LANE client's ATM address.

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

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 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 our 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.

Examples

This example shows how to use 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, designated by the double asterisks:

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

This example shows how to use 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, designated by the ellipses:

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 command to specify the ATM address of a given configuration server. 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
atm-address-template ATM address, or 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

By default, no specific ATM address or method is set.

Command Type

Cisco IOS LANE 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.

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

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 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 our 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.

Example

This example shows how to specify the ATM address of the LANE configuration server:

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

lane config database

Use the lane config database command to associate a named configuration table (database) with the configuration server on the selected ATM interface. To remove the association between a named database and the configuration server, use the no form of this command.

lane config database database-name
no lane config database

Syntax Description
database-name Name of the LANE database.
Default

By default, no configuration server is defined and no database name is provided.

Command Type

Cisco IOS LANE command.

Command Mode

Interface configuration.

Usage Guidelines

This command is valid only on a major interface, not a subinterface, because only one LANE configuration server can exist for a switch cloud.

The named database must exist before you enter the lane config database command. Refer to the lane database command for more information.

You cannot enter multiple lane config database commands on the same interface. You must delete an existing association using the no form of this command before you can enter a new association.

Activating a LANE client requires the lane config database command and one of the following commands: lane fixed-config-atm-address, lane auto-config-atm-address, or lane config-atm address.

Example

This example shows how to associate a named configuration database with the configuration server:

ATM(config)#int atm0
ATM(config-if)#lane config database test
Related Commands

lane auto-config-atm-address
lane config-atm-address
lane database

lane database

Use the lane database command to create a named configuration database that can be associated with a configuration server when one is configured. Use the no form of this command to delete all entries in the specified database.

lane database database-name
no
lane database database-name
Syntax Description
database-name Database name (32 characters maximum).
Default

By default, no name is provided.

Command Type

Cisco IOS LANE command.

Command Mode

Global configuration.

Usage Guidelines

A LANE database contains entries that bind an ELAN name to the ATM address of the LANE server, bind LANE client MAC addresses to an ELAN name, and bind LANE client ATM address templates to an ELAN name.

Entering the lane database command places you in database configuration mode, in which you can enter the client-atm-address name, default name, mac-address name, and name server-atm-address commands to create entries in the specified database. When you are done creating entries, type Ctrl-Z or exit to return to global configuration mode.

Example

This example shows how to create a configuration database named test:

ATM(config)#int atm0
ATM(config-if)#lane database test
ATM(lane-config-database)#end
Related Commands

lane le-arp

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

lane le-arp mac-addr atm-addr
no lane le-arp mac-addr atm-addr
Syntax Description
mac-address MAC address to bind to the specified ATM address.
atm-address ATM address to bind to the specified MAC address.
Default

By default, no static address bindings are provided.

Command Type

Cisco IOS LANE 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, enter the clear lane le-arp command.

Example

This 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
Related Command

show lane le-arp

lane register

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

lane register vcd mac-addr atm-addr
no lane register
vcd [mac-addr atm-addr]
Syntax Description
vcd Virtual channel descriptor of the Server Direct PVC through which the LANE client is connected to the LANE server.
mac-addr MAC address of the LANE client.
atm-addr ATM address of the LANE client.
Default

By default, no PVC is defined and no MAC address and ATM address are provided.

Command Type

Cisco IOS LANE command.

Command Mode

Interface configuration.

Usage Guidelines

Ordinarily, SVCs are used instead of PVCs for communications within ELANs, and registration occurs dynamically via the LANE protocol. Use the lane register command only when you use PVCs.

If you use PVCs 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 ELAN.

Use the lane pvc command on a LANE client and the lane register command on a LANE server to enable 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.

Example

This example shows how to register a LANE client connected by a PVC to the LANE server on the subinterface:

ATM(config)#int atm0.1

ATM(config-subif)#lane register 98 0800.aa00.0101 47.000014155551212f.00.00.0800.200C.1001.01

reload

Use the reload command to reload the operating system.

reload
Syntax Description

This command has no arguments or keywords.

Command Type

Cisco IOS Configuration command.

Command Mode

EXEC.

Usage Guidelines

The reload command halts the ATM module. If you set the ATM module to restart on error, it reboots itself. Use the reload command after you enter configuration information into a file and save 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 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

This example shows how to reload the system from the privileged EXEC prompt:

ATM#reload
