This chapter describes the commands available to configure LAN emulation (LANE) in Cisco 7000 series, Cisco 7500 series and Cisco 4500 routers that contain an ATM Interface Processor (AIP) and are connected to a Cisco ATM switch.
For LANE configuration information and examples, refer to the chapter entitled "Configuring LAN Emulation (LANE)" in the Wide-Area Networking Configuration Guide.
To release a specified switched virtual circuit (SVC), use the clear atm vc EXEC command.
clear atm vc vcd| vcd | Virtual channel descriptor of the channel to be released. |
EXEC
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.
The following example releases SVC 1024:
clear atm vc 1024To 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] [mac-address] | name elan-name| 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 7000 series and Cisco 7500 series routers. |
| 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. |
| mac-address | (Optional) Media access control (MAC) address of the entry to be cleared from the LE ARP table. |
| 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. |
EXEC
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.
Use of this command also removes the fast-cache entries built from the LE ARP entries.
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 called 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 called red:
clear lane le-arp name red
After changing the bindings on a LANE configuration server, to force a LANE server on a specified subinterface or emulated LAN to drop the Control Direct and Control Distribute VCCs to a given LANE client and thus to force the client to rejoin subject to the new bindings, use the clear lane server EXEC command.
clear lane server {interface slot/port[.subinterface-number] | name elan-name}| interface slot/port[.subinterface-number] | Interface or subinterface on which the LANE server is configured for the Cisco 7000 series and Cisco 7500 series. |
| interface number[.subinterface-number] | Interface or subinterface on which the LANE server is configured for the Cisco 4500. |
| 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 lecid | (Optional) Keyword and LANE client ID. |
EXEC
This command first appeared in Cisco IOS Release 11.0.
After changing the bindings on the configuration server, enter this command on the LANE server. The effect is to force the client to leave one emulated LAN and join a different emulated LAN.
If no LANE client is specified, all LANE clients attached to the LANE server are dropped.
The following example forces all the LANE clients on the emulated LAN named red to be dropped. The next time they try to join, they will be forced to join a different emulated LAN.
clear lane server red
A dagger (+) indicates that the command is documented outside this chapter.
client-atm-address name
lane database
mac-address name +
show lane server
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| 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. |
| name elan-name | Name of the emulated LAN. Maximum length is 32 characters. |
No address and no emulated LAN name are provided.
Database configuration
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.
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
A dagger (+) indicates that the command is documented outside this chapter.
default-name
lane database
mac-address name +
name server-atm-address
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| 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. |
No name is provided.
Database configuration
This command first appeared in Cisco IOS Release 11.0.
This command is ordinarily used.
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.
A dagger (+) indicates that the command is documented outside this chapter.
client-atm-address name
lane database
mac-address name +
name server-atm-address
To specify that the configuration server ATM address is computed by our automatic method, use the lane config auto-config-atm-address interface configuration command from the configuration server. To remove the previously assigned ATM address, use the no form of this command.
lane [config] auto-config-atm-address| config | (Optional) Used to specify the configuration server's ATM address. |
No specific ATM address is set.
Interface configuration
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 Wide-Area Networking Configuration Guide.
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 39.0000014155551211.0800.AA00.1001.02 name mkt server-atm-address 39.0000014155551211.0800.AA00.4001.01 lane config database network1 lane config auto-config-atm-address
lane config-atm-address
lane database
lane fixed-config-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| 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. |
For the broadcast-and-unknown server, the default is automatic ATM address assignment.
Interface configuration
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.
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...
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 [elan-name]| ethernet | Identifies the type of emulated LAN attached to this subinterface. |
| elan-name | (Optional) Name of the emulated LAN. This argument is optional because the client obtains its emulated LAN name from the configuration server. Maximum length is 32 characters. |
None
Interface configuration
This command first appeared in Cisco IOS Release 11.0.
This command is ordinarily used.
If a lane client command has already been entered on the subinterface for a different emulated LAN, then the client initiates termination procedures for that emulated LAN and joins the new emulated LAN.
If you do not provide an elan-name value, the client contacts the server to find which emulated LAN to join. If you do provide an emulated LAN name, the client consults the configuration server to ensure that no conflicting bindings exist.
To specify an ATM address--and thus override the automatic ATM address assignment--for the LANE client on the specified subinterface, use the lane client-atm-address interface configuration command. To remove the ATM address previously specified for the LANE client on the specified subinterface and thus revert to the automatic address assignment, use the no form of this command.
lane client-atm-address atm-address-template| 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. |
Automatic ATM address assignment.
Interface configuration
This command first appeared in Cisco IOS Release 11.0.
Use of this command on a selected subinterface, but with a different ATM address than was used previously, replaces the LANE client's ATM address.
ATM Addresses. A LANE ATM address has the same syntax as an NSAP (but it is not a network-level address). 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 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.
For a discussion of Cisco's method of automatically assigning ATM addresses, refer to the "Configuring LAN Emulation (LANE)" chapter in the Wide-Area Networking Configuration Guide.
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 client-atm-address...0800.200C.1001.**
The following example uses a prefix template to specify the part of the ATM address corresponding to the switch; the remaining parts of the ATM address come from automatic assignment:
lane client-atm-address 47.000014155551212f.00.00...
To specify a configuration server's ATM address explicitly, use the lane config-atm-address interface configuration command. To remove an assigned ATM address, use the no form of this command.
lane [config] config-atm-address atm-address-template| 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. |
| config | (Optional) Used to specify the configuration server ATM address. |
No specific ATM address or method is set.
Interface configuration
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:
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 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 (LANE)" chapter in the Wide-Area Networking Configuration Guide.
lane auto-config-atm-address
lane config database
lane database
lane fixed-config-atm-address
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| database-name | Name of the LANE database. |
No configuration server is defined, and no database name is provided.
Interface configuration
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 entered. Refer to the lane database command for more information.
Multiple lane config database commands cannot be entered 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.
lane auto-config-atm-address
lane config-atm-address
lane database
lane fixed-config-atm-address
To create a named configuration database that can be associated with a configuration server, use the lane database global configuration command. To delete the database, use the no form of this command.
lane database database-name| database-name | Database name (32 characters maximum). |
No name is provided.
Global configuration
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.
A dagger (+) indicates that the command is documented outside this chapter.
client-atm-address name

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| config | (Optional) Specifies the configuration server ATM address. |
No specific ATM address or method is set.
Interface configuration
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 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 enter this command when a server is not a master, the server will listen on this address when it becomes a master. If you do not enter 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.
lane auto-config-atm-address
lane config-atm-address
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 atm-address| mac-address | MAC address to bind to the specified ATM address. |
| atm-address | ATM address. |
No static address bindings are provided.
Interface configuration
This command first appeared in Cisco IOS Release 11.0.
This command adds or removes a static entry binding a MAC address to an ATM address. It does not add or remove dynamic entries. Removing the static entry for a specified ATM address from an LE ARP table does not release Data Direct VCCs established to that ATM address. However, clearing a static entry clears any fast-cache entries that were created from the MAC address-to-ATM address binding.
Static LE ARP entries are not aged and are not removed automatically.
To remove dynamic entries from the LE ARP table of the LANE client on the specified subinterface, use the clear lane le-arp command.
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
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| 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. |
For the LANE server, the default is automatic address assignment; the LANE client finds the LANE server by consulting the configuration server.
Interface configuration
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 Wide-Area Networking Configuration Guide.
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...
To enable a LANE server and a broadcast-and-unknown server on the specified subinterface, use the lane server-bus interface configuration command. To disable a LANE server and broadcast-and-unknown server on the specified subinterface, use the no form of this command.
lane server-bus ethernet elan-name| ethernet | Identifies the type of emulated LAN attached to this subinterface. |
| elan-name | Name of the emulated LAN. Maximum length is 32 characters. |
No LAN type and emulated LAN name are provided.
Interface configuration
This command first appeared in Cisco IOS Release 11.0.
This command is ordinarily used.
The LANE server and the broadcast-and-unknown server are located on the same router.
If a lane server-bus command has already been entered on the subinterface for a different emulated LAN, then the server initiates termination procedures with all clients and comes up as the server for the new emulated LAN.
Use of the no form of this command removes a previously configured LANE server and broadcast-and-unknown server on the subinterface.
To specify or replace the ATM address of the LANE server for the emulated LAN in the configuration server's configuration database, use the name server-atm-address global configuration command. To remove it from the database, use the no form of this command.
name elan-name server-atm-address atm-address [restricted | un-restricted] [index n]| elan-name | Name of the emulated LAN. Maximum length is 32 characters. |
| atm-address | LANE server's ATM address. |
| restricted | un-restricted | (Optional) Membership in the named emulated LAN is restricted to the LANE clients explicitly defined to the emulated LAN in the configuration server's database. |
| index n | (Optional) Priority number. When specifying multiple LANE servers for fault tolerance, you can specify a priority for each server. 0 is the highest priority. |
No emulated LAN name or server ATM address are provided.
Database configuration
This command first appeared in Cisco IOS Release 11.0. The restricted command first appeared in Cisco IOS Release 11.1. The unrestricted and index commands 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 entered multiple times.
The no form of this command deletes the relationships.
A dagger (+) indicates that the command is documented outside this chapter.

To display detailed information for all the LANE components configured on an interface or any of its subinterfaces, on a specified subinterface, or on an emulated LAN, use the show lane EXEC command.
show lane [interface atm slot/port[.subinterface-number] | name elan-name] [brief]| interface atm slot/port | (Optional) ATM interface slot and port for the Cisco 7000 series and Cisco 7500 series. |
| interface atm number | (Optional) ATM interface number for the Cisco 4500. |
| .subinterface-number | (Optional) Subinterface number. |
| name elan-name | (Optional) Name of emulated LAN. Maximum length is 32 characters. |
| brief | (Optional) Keyword used to display the brief subset of available information. |
EXEC
The show lane [interface atm slot/port[.subinterface-number] | name elan-name] [brief] command first appeared in Cisco IOS Release 11.0.
The show lane [interface atm number[.subinterface-number] | name elan-name] [brief] command first appeared in Cisco IOS Release 11.1.
Entering the show lane command is equivalent to entering the show lane config, show lane server, show lane bus, and show lane client commands. The show lane command shows all LANE-related information except the show lane database information.
The following is sample output of the show lane command:

The show lane config [interface atm number]] command first appeared in Cisco IOS Release 11.1.
The following is sample output from the show lane config command when the configuration server has two ATM addresses:
Router# show lane config
LE Config Server ATM1/0 config table: table State: operational
ATM Address: 39.000000000000000000000000.000000000500.00

cumulative total number of unrecognized packets received so far: 0
cumulative total number of config requests received so far: 10
cumulative total number of config failures so far: 0
In the following case, although the configuration server is operational, its addresses are not completely registered. The first address is not registered with the ILMI, as indicated by the ilmi- state. The second address has the same problem plus the problem of not having been registered with the ATM signaling subsystem, as indicated by the atmsig- state.
Router# show lane config

cumulative total number of unrecognized packets received so far: 0
cumulative total number of config requests received so far: 10

In the following case, some physical connectivity problem must have occurred and as a result, the configuration server's ATM address has not yet been determined definitively. Either the prefix has not been obtained, or it is not there. As a result, the address cannot be computed and hence you see the "EXACT ADDRESS NOT YET SET (NO PREFIX ?)" message.

Table 40 describes significant fields shown in the display.
| Field | Description |
|---|---|
| interface | Subinterface on which this LANE server is configured. |
| name | Name of the emulated LAN. |
| type | LAN type. This release supports Ethernet only. |
| MTU | Maximum transmission unit (packet) size for this type of LAN. |
| AAL5-SDU length | Maximum number of bytes in a LANE service data unit (SDU) encapsulated in an AAL5 frame. This length includes a 2-byte marker and a full Ethernet-like frame from the destination MAC address field through the last byte of data. It does not include an Ethernet CRC (or FRC), which is not present on emulated LAN frames. The number does not include the 8-byte AAL-5 trailer in the last ATM cell of the frame, nor the padding between the last data byte and the 8-byte trailer. |
| NSAP | ATM address of this LANE server. |
| lecid | Unique LANE client identifier of the LANE client at the other end of this VCC. |
| proxy | When a LANE client joins an emulated LAN, it includes a "proxy" bit that tells the LANE server that the LANE client does not guarantee to register all its MAC address-ATM address pairs with the LANE server. Our LANE clients must set the proxy bit. Workstation LANE clients directly attached to ATM will not set it. |
| vcd | Unique virtual circuit descriptor for the VCC. |
| cnt | For Control Direct VCCs, the number of packets sent from the LANE client to the LANE server.
For Control Distribute VCCs, the number of packets sent from the LANE server to the LANE clients. |
| MAC | Type of VCC, or the MAC address of the device on the other end of this VCC. |
| NSAP | For Control Direct VCCs, the ATM address of the LANE client on the other end of this VCC.
For Control Distribute VCCs, the ATM address of the LANE server. |
