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 Modes

This command was introduced.


Usage Guidelines

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.

Examples

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.

Cisco 7500 series

clear lane le-arp [interface slot/port[.subinterface-number] | name elan-name] [mac-address mac-address | route-desc segment segment-number bridge bridge-number]

Cisco 4500 and 4700 routers

clear lane le-arp [interface number[.subinterface-number] | name elan-name] [mac-address mac-address | route-desc segment segment-number bridge bridge-number]

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.

11.0

This command was introduced.


Usage Guidelines

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.

Cisco 7500 Series

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]

Cisco 4500 and 4700 Routers

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]

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

Modification

11.0

This command was introduced.


Usage Guidelines

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.

Examples

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

Related Commands

Command
Description

client-atm-address name

Adds a LANE client address entry to the configuration database of the configuration server.

lane database

Creates a named configuration database that can be associated with a configuration server.

mac-address

Sets the MAC layer address of the Cisco Token Ring.

show lane server

Displays global information for the LANE server configured on an interface, on any of its subinterfaces, on a specified subinterface, or on an ELAN.


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.


Defaults

No address and no emulated LAN name are provided.

Command Modes

Database configuration

Command History

Release
Modification

11.0

This command was introduced.


Usage Guidelines

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:

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 the 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 (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

clear vlan

To delete an existing virtual LAN (VLAN) from a management domain, use the clear vlan command in privileged EXEC mode.

clear vlan vlan

Syntax Description

vlan

Number of the VLAN. Valid value are 2 to 1000.


Command Modes

Privileged EXEC

Command History

Release
Modification

12.0

This command was introduced.


Usage Guidelines

Follow these guidelines for deleting VLANs:

When you delete an Ethernet VLAN in Virtual Terminal Protocol (VTP) server mode, the VLAN is removed from all switches in the same VTP domain.

When you delete a VLAN in VTP transparent mode, the VLAN is deleted only on the current switch.

To delete a Token Ring Bridge Relay Function (TRBRF) VLAN, you must either first reassign its child Token Ring Concentrator Relay Functions (TRCRFs) to another parent TRBRF or delete the child TRCRFs.


Caution When you clear a VLAN, all ports assigned to that VLAN become inactive. However, the VLAN port assignments are retained until you move the ports to another VLAN. If the cleared VLAN is reactivated, all ports still configured on that VLAN are also reactivated. A warning is displayed if you clear a VLAN that exists in the mapping table.

Examples

The following example shows how to clear an existing VLAN (VLAN 4) from a management domain:

Router# clear vlan 4 
This command will deactivate all ports on vlan 4 
in the entire management domain 
Do you want to continue(y/n) [n]? y 
VLAN 4 deleted

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.


Defaults

No name is provided.

Command Modes

Database configuration

Command History

Release
Modification

11.0

This command was introduced.


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 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.

Examples

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 [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.


Defaults

No specific ATM address is set.

Command Modes

Command History

Release
Modification

11.0

This command was introduced.


Usage Guidelines

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

Specifies that the fixed configuration server ATM address assigned by the ATM Forum will be used.


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.


Defaults

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

Command Modes

Command History

Release
Modification

11.0

This command was introduced.


Usage Guidelines

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:

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)

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 (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 {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.


Defaults

No LANE clients are enabled on the interface.

Command Modes

Usage Guidelines

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.

Examples

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

Usage Guidelines

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.

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:

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.


Defaults

No specific ATM address or method is set.

Command Modes

Modification

11.0

This command was introduced.


Usage Guidelines

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:

If you configure the LECS with only the well-known address, the LECS will not participate in the SSRP, act as a "standalone" master, and only listen on the well-known LECS address. This scenario is ideal if you want a "standalone" LECS that does not participate in SSRP, and you would like to listen to only the well-known address.

If only the well-known address is already assigned, and you assign at least one other address to the LECS, (additional addresses are assigned using the lane config auto-config-atm-address command and/or the lane config config-atm-address command) the LECS will participate in the SSRP and act as the master or slave based on the normal SSRP rules. This scenario is ideal if you would like the LECS to participate in SSRP, and you would like to make the master LECS listen on the well-known address.

If the LECS is participating in SSRP, has more than one address (one of which is the well-known address), and all the addresses but the well-known address is removed, the LECS will declare itself the master and stop participating in SSRP completely.

If the LECS is operating as an SSRP slave, and it has the well-known address configured, it will not listen on the well-known address unless it becomes the master.

If you want the LECS to assume the well-known address only when it becomes the master, configure the LECS with the well-known address and at least one other address.

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 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 fixed-config-atm-address

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

interface atm 2/0.1
 ip address 172.16.0.4 255.255.255.0

Release
Modification

11.2

This command was introduced.


Usage Guidelines

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

11.0

This command was introduced.


Usage Guidelines

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 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

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.


Defaults

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

Usage Guidelines

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:

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)

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 (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...

Usage Guidelines

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.

Examples

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

This command was introduced.


Usage Guidelines

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.

Examples

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

name MYELAN preempt

You cannot set multiple VLANs for Inter-Switch Link (ISL) ports using this command. The VLAN name can be from 1 to 32 characters in length. If adding a new VLAN, the VLAN number must be within the range 2 to 1001. When modifying a VLAN, the valid range for the VLAN number is 2 to 1005.

On a new Token Ring VLAN, if you do not specify the parent parameter for a TRCRF, the default TRBRF (1005) is used.

Examples

The following example shows how to set VLAN 850 to include ports 4 through 7 on module 3. Because ports 4 through 7 were originally assigned to TRCRF 1003, the message reflects the modification of VLAN 1003.

Router# set vlan 850 3/4-7
VLAN 850 modified.
VLAN 1003 modified.
VLAN  Mod/Ports

Related Commands

Command
Description

clear vlan

Deletes an existing VLAN from a management domain.

show vlans

Displays VLAN subinterfaces.



set vlan mapping

To map 802.1Q virtual LANs (VLANs) to Inter-Switch Link (ISL) VLANs, use the set vlan mapping command in privileged EXEC mode.

set vlan mapping dot1q 1q-vlan-number isl isl-vlan-number

Syntax Description

dot1q

Specifies the 802.1Q VLAN.

1q-vlan-number

Number identifying the 802.1Q VLAN; valid values are 1001 to 4095.

isl

Specifies the ISL VLAN.

isl-vlan-number

Number identifying the ISL VLAN; valid values are 1 to 1000.


Defaults

No 802.1Q-to-ISL mappings are defined.

Command Modes

Privileged EXEC

Usage Guidelines

IEEE 802.1Q VLAN trunks support VLANs 1 through 4095. ISL VLAN trunks support VLANs 1 through 1000. The switch automatically maps 802.1Q VLANs 1000 and lower to ISL VLANs with the same number.

The native VLAN of the 802.1Q trunk cannot be used in the mapping.

Use this feature to map 802.1Q VLANs above 1000 to ISL VLANs. Note that if you map a 802.1Q VLAN over 1000 to an ISL VLAN, the corresponding 802.1Q VLAN will be blocked. For example, if you map 802.1Q VLAN 2000 to ISL VLAN 200, then 802.1Q VLAN 200 will be blocked.

You can map up to seven VLANs. Only one 802.1Q VLAN can be mapped to an ISL VLAN. For example, if 802.1Q VLAN 800 has been automatically mapped to ISL VLAN 800, do not manually map any other 802.1Q VLANs to ISL VLAN 800.

You cannot overwrite existing 802.1Q VLAN mapping. If the 802.1Q VLAN number is in the mapping table, the command is aborted. You must first clear that mapping.

If vlan-number does not exist, then either of the following occurs:

If the switch is in server or transparent mode, the VLAN is created with all default values.

If the switch is in client mode, then the command proceeds without creating the VLAN. A warning will be given indicating that the VLAN does not exist.

If the table is full, the command is aborted with an error message indicating the table is full.

Examples

The following example shows how to map VLAN 1022 to ISL VLAN 850:

Router# set vlan mapping dot1q 1022 isl 850
Vlan 850 configuration successful
Vlan mapping successful

The following example shows the display if you enter a VLAN that does not exist:

Router# set vlan mapping dot1q 1017 isl 999
Vlan mapping successful
Warning: vlan 999 non-existent
Vlan 999 configuration successful

The following example shows the display if you enter an existing mapping:

Router# set vlan mapping dot1q 1033 isl 722
722 exists in the mapping table. Please clear the mapping first.

The following example shows the display if the mapping table is full:

Router# set vlan mapping dot1q 1099 isl 917
Vlan Mapping Table Full.
