LAN Emulation Commands

LAN Emulation Commands

This chapter describes the commands available to configure LAN emulation (LANE) in Cisco  4500 series routers, Cisco  4700 routers, and Cisco  7500 routers that contain an ATM Interface Processor (AIP) or an NP-1A ATM Network Processor Module (NPM) and are connected to a Cisco  ATM switch.

For LANE configuration information and examples, refer to the chapter entitled "Configuring LAN Emulation" in the Cisco IOS Switching Services Configuration Guide.


Note Because some LANE commands are used often and others are used very rarely, the command descriptions identify the commands you are most likely to use. See the "Usage Guidelines" section for the following indicator: "This command is ordinarily used."

clear atm vc

To release a specified switched virtual circuit (SVC), use the clear atm vc EXEC command.

clear atm vc vcd

Syntax Description

vcd

Virtual channel descriptor of the channel to be released.

Command Mode

EXEC

Usage Guidelines

This command first appeared in Cisco IOS Release 11.0.

For multicast or control VCCs, this command causes the LANE client to exit and rejoin an emulated LAN.

For data VCCs, this command also removes the associated LANE Address Resolution Protocol (LE ARP) table entries.

Example

The following example releases SVC 1024:

clear atm vc 1024

clear lane le-arp

To clear the dynamic LANE Address Resolution Protocol (LE ARP) table or a single LE ARP entry of the LANE client configured on the specified subinterface or emulated LAN, use the clear lane le-arp EXEC command.

clear lane le-arp [interface slot/port[.subinterface-number] | name elan-name] [mac-address
mac-address | route-desc segment segment-number bridge bridge-number]
(for the
Cisco  7500 series)
clear lane le-arp [interface number[.subinterface-number] | name elan-name] [mac-address
mac-address | route-desc segment segment-number bridge bridge-number]] (for the
Cisco  4500 and 4700 routers)

Syntax Description

interface slot/port[.subinterface-number]

(Optional) Interface or subinterface for the LANE client whose LE ARP table or entry is to be cleared for the Cisco  7500 series routers. The space between the interface keyword and the slot argument is optional.

interface number[.subinterface-number]

(Optional) Interface or subinterface for the LANE client whose LE ARP table or entry is to be cleared for the Cisco  4500 or 4700 routers. The space between the interface keyword and the number argument is optional.

name elan-name

(Optional) Name of the emulated LAN for the LANE client whose LE ARP table or entry is to be cleared. Maximum length is 32 characters.

mac-address mac-address

(Optional) Media access control (MAC) address of the entry to be cleared from the LE  ARP table.

route-desc segment segment-number

(Optional) LANE segment number. The segment number ranges from 1 to 4095.

bridge bridge-number

(Optional) Bridge number that is contained in the route descriptor. Valid bridge numbers range from 1 to 15.

Command Mode

EXEC

Usage Guidelines

This command first appeared in Cisco IOS Release 11.0.

This command removes dynamic LE ARP table entries only. It does not remove static LE ARP table entries.

If you do not specify an interface or an emulated LAN, this command clears all the LE ARP tables of any LANE client in the router.

If you specify a major interface (not a subinterface), this command clears all the LE ARP tables of every LANE client on all the subinterfaces of that interface.

This command also removes the fast-cache entries built from the LE ARP entries.

Examples

The following example clears all the LE ARP tables for all clients on the router:

clear lane le-arp

The following example clears all the LE ARP tables for all LANE clients on all the subinterfaces of interface 1/0:

clear lane le-arp interface 1/0

The following example clears the entry corresponding to MAC address 0800.AA00.0101 from the LE ARP table for the LANE client on the emulated LAN red:

clear lane le-arp name red 0800.aa00.0101

The following example clears all dynamic entries from the LE ARP table for the LANE client on the emulated LAN red:

clear lane le-arp name red 

The following example clears the dynamic entry from the LE ARP table for the LANE client on segment number 1, bridge number 1 in the emulated LAN red:

clear lane le-arp name red route-desc segment 1 bridge 1

Note MAC addresses are written in the same dotted notation for the clear lane le-arp command as they are for the global IP arp command.

clear lane server

To force a LANE server to drop a client and allow the LANE configuration server to assign the client to another emulated LAN, use the clear lane server EXEC command.

clear lane server {interface slot/port [.subinterface-number] | name elan-name}
[mac-address mac-address | client-atm-address atm-address | lecid lane-client-id |
route-desc segment segment-number bridge bridge-number]
 
(for the Cisco  7500 series)

clear lane server {interface number [.subinterface-number] | name elan-name}
[mac-address mac-address | client-atm-address atm-address | lecid lecid |
route-desc segment segment-number bridge bridge-number]
(for the Cisco  4500 and 4700 routers)

Syntax Description

interface slot/port[.subinterface-number]

Interface or subinterface where the LANE server is configured for the Cisco  7500 series. The space between the interface keyword and the slot argument is optional.

interface number[.subinterface-number]

Interface or subinterface where the LANE server is configured for the Cisco  4500 or 4700 routers. The space between the interface keyword and the number argument is optional.

name elan-name

Name of the emulated LAN on which the LANE server is configured. Maximum length is 32  characters.

mac-address mac-address

(Optional) Keyword and LANE client's MAC address.

client-atm-address atm-address

(Optional) Keyword and LANE client's ATM address.

lecid lane-client-id

(Optional) Keyword and LANE client ID. The LANE client ID is a value between 1 and 4096.

route-desc segment segment-number

(Optional) Keywords and LANE segment number. The segment number ranges from 1 to 4095.

bridge bridge-number

(Optional) Keyword and bridge number that is contained in the route descriptor. The bridge number ranges from 1 to 15.

Command Mode

EXEC

Usage Guidelines

This command first appeared in Cisco IOS Release 11.0.

After changing the bindings on the configuration server, use this command on the LANE server to force the client to leave one emulated LAN. The LANE server will drop the Control Direct and Control Distribute VCCs to the LANE client. The client will then ask the LANE configuration server for the location of the LANE server of the emulated LAN it should join.

If no LANE client is specified, all LANE clients attached to the LANE server are dropped.

Example

The following example forces all the LANE clients on the emulated LAN red to be dropped. The next time they try to join, they will be forced to join a different emulated LAN.

clear lane server name red

client-atm-address name

To add a LANE client address entry to the configuration server's configuration database, use the client-atm-address database configuration command. To remove a client address entry from the table, use the no form of this command.

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, making it easy and convenient to specify multiple addresses matching the explicitly specified part.

Wildcard characters can replace any nibble or group of nibbles in the prefix, the end-system identifier (ESI), or the selector fields of the ATM address.

elan-name

Name of the emulated LAN. Maximum length is 32  characters.

Default

No address and no emulated LAN name are provided.

Command Mode

Database configuration

Usage Guidelines

This command first appeared in Cisco IOS Release 11.0.

This command is ordinarily used.

The effect of this command is to bind any client whose address matches the specified template into the specified emulated LAN. When a client comes up, it consults the LANE configuration server, which responds with the ATM address of the LANE server for the emulated LAN. The client then initiates join procedures with the LANE server.

Before this command is used, the emulated LAN specified by the elan-name argument must have been created in the configuration server's database by use of the name server-atm-address command.

If an existing entry in the configuration server's database binds the LANE client ATM address to a different emulated LAN, 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.

See the lane database command for information about creating the database, and the name server-atm-address command for information about binding the emulated LAN's name to the server's ATM address.

The client-atm-address name command is a subcommand of the global lane database command.

ATM Addresses. A LANE ATM address has the same syntax as a network service access point (NSAP) but it is not a network-level address. It consists of the following:

Address Templates. LANE ATM address templates can use two types of wildcards: an asterisk (*) to match any single character (nibble), and an ellipsis (...) to match any number of leading, middle, 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 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

The following example uses an ESI template to specify the part of the ATM address corresponding to the interface. This example 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 emulated LAN:

client-atm-address ...0800.200C.1001.** name engineering

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

client-atm-address 47.000014155551212f.00.00... name marketing

default-name

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

default-name elan-name
no default-name

Syntax Description

elan-name

Default emulated LAN name for any LANE client MAC address or LANE client ATM address not explicitly bound to any emulated LAN name. Maximum length is 32 characters.

Default

No name is provided.

Command Mode

Database configuration

Usage Guidelines

This command first appeared in Cisco IOS Release 11.0.

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

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

The default-name command is a subcommand of the global lane database command.

Example

The following example specifies the emulated Token Ring LAN man as the default emulated LAN. Because none of the emulated LANs are restricted, clients are assigned to whichever emulated LAN they request. Clients that do not request a particular emulated LAN will be assigned to the man emulated LAN.

lane auto-config-atm-address

To specify that the configuration server ATM address is computed by our automatic method, use the lane auto-config-atm-address interface configuration command. 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) When the config keyword is used, this command applies only to the LANE configuration server (LECS). This keyword indicates that the LECS should use the auto-computed LECS address.

Default

No specific ATM address is set.

Command Mode

Interface configuration

Usage Guidelines

This command first appeared in Cisco IOS Release 11.0.

When the config keyword is not present, this command causes the LANE server and LANE client on the subinterface to use the automatically assigned ATM address for the configuration server.

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

For a discussion of Cisco's method of automatically assigning ATM addresses, refer to the "Configuring LAN Emulation (LANE)" chapter in the Cisco IOS Switching Services Configuration Guide.

Examples

The following example associates the LANE configuration server with the database named network1 and specifies that the configuration server's ATM address will be assigned by our automatic method:

lane database network1
  name eng server-atm-address 39.020304050607080910111213.0800.AA00.1001.02
  name mkt server-atm-address 39.020304050607080910111213.0800.AA00.4001.01
interface atm 1/0
  lane config database network1
  lane config auto-config-atm-address

The following example causes the LANE server and LANE client on the subinterface to use the automatically assigned ATM address to communicate with the configuration server:

interface atm 2/0.1
  ip address 172.16.0.4 255.255.255.0
  lane client ethernet
  lane server-bus ethernet eng
  lane auto-config-atm-address

lane bus-atm-address

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

lane bus-atm-address atm-address-template
no lane bus-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 end-system identifier (ESI) bytes, or the selector byte of the automatically assigned ATM address.

Default

For the broadcast-and-unknown server, the default is automatic ATM address assignment.

Command Mode

Interface configuration

Usage Guidelines

This command first appeared in Cisco IOS Release 11.0.

When applied to a broadcast-and-unknown server, this command overrides automatic ATM address assignment for the broadcast-and-unknown server. When applied to a LANE client, this command gives the client the ATM address of the broadcast-and-unknown server. The client will use this address rather than sending LE ARP requests for the broadcast address.

When applied to a selected interface, but with a different ATM address than was used previously, this command replaces the broadcast-and-unknown server's ATM address.

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

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

The values of the digits that are replaced by wildcards come from the automatic ATM assignment method.

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 switch, the ESI corresponds to the ATM interface, and the Selector field corresponds to the specific subinterface of the interface.

Examples

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

lane bus-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 values in the ATM address come from automatic assignment:

lane bus-atm-address 45.000014155551212f.00.00...

lane client

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

lane client {ethernet | tokenring} [elan-name]
no lane client
[{ethernet | tokenring} [elan-name]]

Syntax Description

ethernet

Identifies the emulated LAN attached to this subinterface as an Ethernet ELAN.

tokenring

Identifies the emulated LAN attached to this subinterface as a Token Ring ELAN.

elan-name

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

Default

No LANE clients are enabled on the interface.

Command Mode

Interface configuration

Usage Guidelines

This command first appeared in Cisco IOS Release 11.0.

If a lane client command has already been used 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

The following example enables a Token Ring LANE client on an interface:

lane client tokenring

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

Syntax Description

config

(Optional) When the config keyword is used, this command applies only to the LANE configuration server (LECS). This keyword indicates that the LECS should use the 20-byte address that you explicitly entered.

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

No specific ATM address or method is set.

Command Mode

Interface configuration

Usage Guidelines

This command first appeared in Cisco IOS Release 11.0.

If the config keyword is not present, this command causes the LANE server and LANE client on the subinterface to use the specified ATM address for the configuration server.

When the config keyword is present, this command adds an ATM address to the configuration server configured on the interface. A LANE configuration server can listen on multiple ATM addresses. Multiple commands that assign ATM addresses to the LANE configuration server can be issued on the same interface to assign different ATM addresses to the LANE configuration server.

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

LANE ATM address templates can use two types of wildcards: an asterisk (*) to match any single character (nibble), and an ellipsis (...) to match any number of leading, middle, 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 prefix, the ESI corresponds to a function of ATM interface's MAC address, 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 Cisco IOS Switching Services Configuration Guide.

Examples

The following example associates the LANE configuration server with the database named network1 and explicitly specifies the configuration server's ATM address:

lane database network1
  name eng server-atm-address 39.020304050607080910111213.0800.AA00.1001.02

  lane config config-atm-address 39.020304050607080910111213.0800.AA00.3000.00

The following example causes the LANE server and LANE client on the subinterface to use the explicitly specified ATM address to communicate with the configuration server:

interface atm 2/0.1
  ip address 172.16.0.4 255.255.255.0
  lane client ethernet

lane config database

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

lane config database database-name
no lane config

Syntax Description

database-name

Name of the LANE database.

Default

No configuration server is defined, and no database name is provided.

Command Mode

Interface configuration

Usage Guidelines

This command first appeared in Cisco IOS Release 11.0.

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

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

Multiple lane config database commands cannot be used multiple times on the same interface. You must delete an existing association by using the no form of this command before you can create a new association on the specified interface.

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

Example

The following example associates the LANE configuration server with the database named network1 and specifies that the configuration server's ATM address will be assigned by our automatic method:

lane database network1
  name eng server-atm-address 39.020304050607080910111213.0800.AA00.1001.02

Syntax Description

database-name

Database name (32  characters maximum).

Default

No name is provided.

Command Mode

Global configuration

Usage Guidelines

This command first appeared in Cisco IOS Release 11.0.

Use of the lane database command places you in database configuration mode, in which you can use the client-atm-address name, default name, mac-address name, name restricted, name unrestricted, name new-name, and name server-atm-address commands to create entries in the specified database. When you are finished creating entries, type ^Z or exit to return to global configuration mode.

Example

The following example creates the database named network1 and associates it with the configuration server on interface ATM 1/0:

lane database network1
  name eng server-atm-address 39.020304050607080910111213.0800.AA00.1001.02

lane fixed-config-atm-address

To specify that the fixed configuration server ATM address assigned by the ATM Forum will be used, use the lane fixed-config-atm-address interface configuration command. To specify that the fixed ATM address is not used, use the no form of this command.

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

Syntax Description

config

(Optional) When the config keyword is used, this command applies only to the LANE configuration server (LECS). This keyword indicates that LECS should use the well-known, ATM Forum, LEC address.

Default

No specific ATM address or method is set.

Command Mode

Interface configuration

Usage Guidelines

This command first appeared in Cisco IOS Release 11.0.

When the config keyword is not present, this command causes the LANE server and LANE client on the subinterface to use that ATM address, rather than the ATM address provided by the ILMI, to locate the configuration server.

When the config keyword is present, and the LECS is already up and running, please be aware of the following scenarios:

When you use this command with the config keyword, and the LAN Emulation Configuration Server (LECS) is a master, the master will listen on the fixed address. If you use this command when an LECS is not a master, the LECS will listen on this address when it becomes a master. If you do not use this command, the LECS will not listen on the fixed address.

Multiple commands that assign ATM addresses to the LECS can be issued on the same interface in order 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. The lane config database command and at least one command that assigns an ATM address to the LECS are required to activate a LECS.

Examples

The following example associates the LANE configuration server with the database named network1 and specifies that the configuration server's ATM address is the fixed address:

lane global-lecs-address

To specify a list of LECS addresses to use when the addresses cannot be obtained from the ILMI, use the lane global-lecs-address interface configuration command. The no form of this command removes an LECS address from the list.

lane global-lecs-address address
no lane global-lecs-address address

Syntax Description

address

Address of the LECS. You cannot use the well-known LECS address.

Default

No addresses are configured. The router obtains LECS addresses from the ILMI.

Command Mode

Interface configuration

Usage Guidelines

This command first appeared in Cisco IOS Release 11.2.

Use this command when your ATM switches do not support the ILMI list of LECS addresses and you want to configure Simple Server Redundancy. This command will simulate the list of LECS addresses, as if they were obtained from the ILMI. Use this command with a different address for each LECS. The order they are used determines their priority. You should enter the addresses in the same order as you would on the ATM switch.


Note You must configure the same list of addresses on each interface that contains a LANE entity.

If your switches do support ILMI, this command force the router to use the addresses specified and will not use the ILMI to obtain the LECS addresses.

Since the well-known LECS address is always used as a last resort LECS address, you cannot use the address in this command.

lane le-arp

To add a static entry to the LE ARP table of the LANE client configured on the specified subinterface, use the lane le-arp interface configuration command. 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 | route-desc segment segment-number bridge bridge-number}
atm-address
no lane le-arp {mac-address | route-desc segment segment-number bridge bridge-number}
atm-address

Syntax Description

mac-address

MAC address to bind to the specified ATM address.

segment-number

LANE segment number. The segment number ranges from 1 to 4095.

bridge-number

Bridge number that is contained in the route descriptor. The bridge number ranges from 1 to 15.

atm-address

ATM address.

Default

No static address bindings are provided.

Command Mode

Interface configuration

Usage Guidelines

This command first appeared in Cisco IOS Release 11.0.

This command adds or removes a static entry binding a MAC address or segment number and bridge number 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 neither aged nor 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.

Examples

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

lane le-arp 0800.aa00.0101 47.000014155551212f.00.00.0800.200C.1001.01

The following example adds a static entry to the LE ARP table binding segment number 1, bridge number 1 to the ATM address:

lane le-arp route-desc segment 1 bridge 1 39.020304050607080910111213.00000CA05B41.01

lane server-atm-address

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

lane server-atm-address atm-address-template
no server-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

For the LANE server, the default is automatic address assignment; the LANE client finds the LANE server by consulting the configuration server.

Command Mode

Interface configuration

Usage Guidelines

This command first appeared in Cisco IOS Release 11.0.

This command also instructs the LANE client configured on this subinterface to reach the LANE server by using the specified ATM address instead of the ATM address provided by the configuration server.

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

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

Address Templates. LANE ATM address templates can use two types of wildcards: an asterisk (*) to match any single character (nibble), and an ellipsis (...) to match any number of leading, middle, 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 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.

For a discussion of Cisco's method of automatically assigning ATM addresses, refer to the "Configuring LAN Emulation (LANE)" chapter of the Cisco IOS Switching Services 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:

lane server-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 part of the ATM address come from automatic assignment:

lane server-atm-address 45.000014155551212f.00.00...

lane server-bus

lane server-bus

To enable a LANE server and a broadcast-and-unknown server (BUS) on the specified subinterface with the ELAN ID, use the lane server-bus interface configuration command. To disable a LANE server and BUS on the specified subinterface, use the no form of this command.

lane server-bus {ethernet | tokenring} elan-name [elan-id id]
no lane server-bus {ethernet | tokenring} elan-name [elan-id id]

Syntax Description

ethernet

Identifies the emulated LAN attached to this subinterface as an Ethernet emulated LAN (ELAN).

tokenring

Identifies the emulated LAN attached to this subinterface as a Token Ring ELAN.

elan-name

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

elan-id

Identifies the ELAN.

id

Specifies the ELAN ID of the LEC.

Default

No LAN type or emulated LAN name is provided.

Command Mode

Interface configuration

Usage Guidelines

This command first appeared in Cisco IOS Release 11.0.

The elan-id keyword first appeared in Cisco IOS Release 12.0.

The LANE server and the BUS are located on the same router.

If a lane server-bus command has already been used on the subinterface for a different emulated LAN, the server initiates termination procedures with all clients and comes up as the server for the new emulated LAN.

To participate in MPOA, a LEC must have an ELAN ID. This command enables the LEC to get the ELAN ID from the LES when the LEC bypasses the LECS phase.

Caution If an ELAN ID is supplied, make sure that it corresponds to the same ELAN ID value
specified in the LECS for the same ELAN.

The LEC can also obtain the ELAN ID from the LECS by using the name elan-id command.

Example

The following example enables a LANE server and BUS for a Token Ring ELAN named MYELAN:

lane server-bus tokenring myelan

Default

No ELAN ID is configured.

Command Mode

LANE database configuration

Usage Guidelines

This command first appeared in Cisco IOS Release 12.0.

To participate in MPOA, a LEC must have an ELAN ID. The LEC obtains the ELAN ID from the LECS. In case the LEC bypasses the LECS phase, the LEC can get the ELAN ID from the LES by using the name elan-id command.

Example

The following example sets the ELAN ID to 10 for ELAN named MYELAN:

name MYELAN elan-id 10

name preempt

To set the ELAN preempt, use the name preempt LANE database configuration command. To disable preempt, use the no form of this command.

name elan-name preempt
no name
elan-name preempt

Syntax Description

elan-name

Specifies the name of the ELAN.

Default

Preempt is off by default.

Command Mode

LANE database configuration

Usage Guidelines

This command first appeared in Cisco IOS Release 11.3.

Previously, when the primary LES failed, Cisco SSRP protocol switched over to a secondary LES. But when a LES that is ranked higher in the list came back up, the SSRP protocol switched the active LES to the new LES which had a higher priority. This forced the network to flap multiple times. In this release, we have prevented the network flapping by staying with the currently active master LES regardless of the priority. If a higher priority LES comes back online, SSRP will not switch to that LES.

LES preemption is off by default. The first LES that comes on becomes the master. Users can revert to the old behavior (of switching to the higher priority LES all the time) by specifying the name elan-name preempt command in the LECS database.

Example

The following example sets the ELAN preempt for the ELAN named MYELAN:

name MYELAN preempt

name local-seg-id

To specify or replace the ring number of the emulated LAN in the configuration server's configuration database, use the name local-seg-id database configuration command. To remove the ring number from the database, use the no form of this command.

name elan-name local-seg-id segment-number
no name elan-name local-seg-id segment-number

Syntax Description

elan-name

Name of the emulated LAN. The maximum length of the name is 32  characters.

segment-number

Segment number to be assigned to the emulated LAN. The number ranges from 1 to 4095.

Default

No emulated LAN name or segment number is provided.

Command Mode

Database configuration

Usage Guidelines

This command first appeared in Cisco IOS Release 11.3.

This command is ordinarily used for Token Ring LANE.

The same LANE ring number cannot be assigned to more than one emulated LAN.

The no form of this command deletes the relationships.

Example

The following example specifies a ring number of 1024 for the emulated LAN red:

name red local-seg-id 1024

Default

No emulated LAN name or server ATM address are provided.

Command Mode

Database configuration

Usage Guidelines

This command first appeared in Cisco IOS Release 11.0. The restricted command first appeared in Cisco IOS Release 11.1. The un-restricted and index keywords first appeared in Cisco IOS Release  11.2.

Emulated LAN names must be unique within one named LANE configuration database.

Specifying an existing emulated LAN name with a new LANE server ATM address adds the LANE server ATM address for that emulated LAN for redundant server operation or simple LANE service replication. This command can be used multiple times.

The no form of this command deletes the relationships.

Example

The following example configures the example3 database with two restricted and one unrestricted emulated LANs. The clients that can be assigned to the eng and mkt emulated LANs are specified using the client-atm-address commands. All other clients are assigned to the man emulated LAN.
