Use the lane auto-config-atm-address command to specify that the ATM address is computed automatically for the LECS or the LES and LEC, depending on whether the config keyword is used. To remove the previously assigned ATM address, use the no form of this command.
lane [config] auto-config-atm-address
config | (Optional) Keyword to specify the LECS ATM address. |
By default, no specific ATM address or method is set.
IOS ATM command.
Interface configuration.
When the config keyword is not present, this command causes the LES and LEC on the subinterface to use the automatically assigned ATM address for the LECS.
When the config keyword is present, this command assigns the automatically generated ATM address to the LECS configured on the interface. Multiple commands that assign ATM addresses to the LECS can be issued on the same interface to assign different ATM addresses to the LECS. Commands that assign ATM addresses to the LECS include lane auto-config-atm-address, lane config-atm-address, and lane fixed-config-atm-address.
This example shows how to associate the LECS with the database named network1 and how to specify that the LECS's ATM address is automatically assigned:
ATM(config-if)#lane config auto-config-atm-address
lane database network1 name eng server-atm-address 39.0000014155551211.0800.AA00.1001.02 name mkt server-atm-address 39.0000014155551211.0800.AA00.4001.01 lane config network1 lane auto-config-atm-address ATM(config-if)#
lane config database
lane config-atm-address
Use the lane bus-atm-address command to define the ATM address for the LANE BUS. To remove the ATM address for the BUS, use the no form of this command.
lane bus-atm-address bus_name atm-addr
bus_name | Name of the BUS. |
atm-address | ATM address of the BUS. |
This command has no default setting.
IOS ATM command.
Interface configuration.
This example shows how to define the ATM address for the LANE BUS:
ATM(config-if)#lane bus-atm-address
ATM(config-if)#
Use the lane client command to activate a LANE client on the specified subinterface. To remove a previously activated LANE client on the subinterface, use the no form of this command.
lane client [ethernet vlan_num [elan-name]]
ethernet | Keyword to indicate the type of ELAN attached to the interface. |
vlan_num | Number of the VLAN that corresponds to the specified ELAN. |
elan-name | (Optional) Name of the ELAN. This argument is optional because the client obtains its ELAN name from the configuration server. Maximum length for elan-name is 32 characters. |
This command has no default setting.
IOS ATM command.
Interface configuration.
If you already entered a lane client command on the subinterface for a different ELAN, the client initiates termination procedures for that ELAN and joins the new ELAN.
If you do not provide an elan-name value, the client contacts the server to find which ELAN to join. If you provide an elan-name value, the client consults the configuration server to ensure that no conflicting bindings exist.
This example shows how to activate the LANE client for a VLAN 3 called eng:
ATM(config-subif)#lane client ethernet vlan 3 eng
Use the lane client-atm-address command to specify an ATM address and to override automatic ATM address assignment for the LANE client on the specified subinterface. To remove the ATM address previously specified for the LANE client on the specified subinterface and revert to automatic address assignment, use the no form of this command.
lane client-atm-address atm-address-template
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.
IOS ATM command.
Interface configuration.
If you use this command on a selected subinterface, but with a different ATM address than was used previously, it replaces the LANE client's ATM address.
A LANE ATM address has the same syntax as an NSAP (but it is not a network-level address):
LANE ATM address templates can use two types of wildcards: an asterisk (*) to match any single character and an ellipsis (...) to match any number of leading or trailing characters. The values of the characters replaced by wildcards come from the automatically assigned ATM address.
In LANE, a prefix template matches the ATM address prefix explicitly but uses wildcards for the ESI and selector fields. An ESI template matches the ESI field explicitly 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.
This example shows how to use an ESI template to specify the part of the ATM address corresponding to the interface; the remaining parts of the ATM address come from automatic assignment, designated by the double asterisks:
ATM(config-if)#lane client-atm-address...0800.200C.1001.**
This example shows how to use a prefix template to specify the part of the ATM address corresponding to the switch; the remaining parts of the ATM address come from automatic assignment, designated by the ellipses:
ATM(config-if)#lane client-atm-address 47.000014155551212f.00.00...
Use the lane client mpoa client name command to bind a LEC to the named MPC. Use the no form of this command to unbind the named MPC from a LEC.
lane client mpoa client name mpc-name
mpc-name | Name of the specific MPC. |
This command has no default setting.
IOS ATM command.
Interface configuration.
When you enter this command, the named MPC binds to a LEC. The named MPC must exist before this command is accepted. If you enter this command before a LEC is configured (not necessarily running), a warning message is issued.
This example shows how to bind a LEC on a subinterface to the MPC:
ATM (config-subif)#lane client mpoa client name ip_mpc
ATM (config-subif)#
Use the lane config-atm-address command to specify the ATM address of a given configuration server. To remove an assigned ATM address, use the no form of this command.
lane config-atm-address atm-address-template
atm-address-template | ATM address or template in which wildcard characters are replaced by any nibble or group of nibbles of the prefix bytes, the ESI bytes, or the selector byte of the automatically assigned ATM address. |
By default, no specific ATM address or method is set.
IOS ATM command.
Interface configuration.
This command causes the LANE client on the subinterface to use the specified ATM address (rather than the ATM address provided by the ILMI) to locate the configuration server.
A LANE ATM address has the same syntax as an NSAP (but it is not a network-level address):
LANE ATM address templates can use two types of wildcards: an asterisk (*) to match any single character and an ellipsis (...) to match any number of leading or trailing characters. The values of the characters replaced by wildcards come from the automatically assigned ATM address.
In LANE, a prefix template explicitly matches the ATM address prefix but uses wildcards for the ESI and selector fields. An ESI template explicitly matches the ESI field but uses wildcards for the prefix and selector.
In our implementation of LANE, the prefix corresponds to the switch, the ESI corresponds to the ATM interface, and the Selector field corresponds to the specific subinterface of the interface.
This example shows how to specify the ATM address of the LANE configuration server:
ATM(config-subif)#lane config-atm-address 39.000000000000014155551211.0800200c1001.00
Use the lane config database command to associate a named configuration table (database) with the configuration server on the selected ATM interface. To remove the association between a named database and the configuration server, use the no form of this command.
lane config database database-name
database-name | Name of the LANE database. |
By default, no configuration server is defined, and no database name is provided.
IOS ATM command.
Interface configuration.
This command is valid only on a major interface, not a subinterface, because only one LANE configuration server can exist for a switch cloud.
The named database must exist before you enter the lane config database command. Refer to the lane database command for more information.
You cannot enter multiple lane config database commands on the same interface. You must delete an existing association using the no form of this command before you can enter a new association.
Activating a LANE client requires the lane config database command and one of these commands: lane fixed-config-atm-address, lane auto-config-atm-address, or lane config-atm address.
This example shows how to associate a named configuration database with the configuration server:
ATM(config)#int atm0
ATM(config-if)#lane config database test
lane auto-config-atm-address
lane config-atm-address
lane database
Use the lane database command to create a named configuration database that can be associated with a configuration server when one is configured. Use the no form of this command to delete all entries in the specified database.
lane database database-name
database-name | Database name (32 characters maximum). |
By default, no name is provided.
IOS ATM command.
Global configuration.
A LANE database contains entries that bind an ELAN name to the ATM address of the LANE server, bind LANE client MAC addresses to an ELAN name, and bind LANE client ATM address templates to an ELAN name.
Entering the lane database command places you in database configuration mode, in which you can enter the client-atm-address name, default name, mac-address name, and name server-atm-address commands to create entries in the specified database. When you are done creating entries, type Ctrl-Z or exit to return to global configuration mode.
This example shows how to create a configuration database named test:
ATM(config)#int atm0
ATM(config-if)#lane database test
ATM(lane-config-database)#end
client-atm-address name
default-name
name
Use the lane le-arp command to add a static entry to the LE ARP table of the LANE client configured on the subinterface. To remove a static entry, use the no form of this command.
lane le-arp mac-addr atm-addr
mac-address | MAC address to bind to the specified ATM address. |
atm-address | ATM address to bind to the specified MAC address. |
By default, no static address bindings are provided.
IOS ATM command.
Interface configuration.
This command only adds or removes a static entry binding a MAC address to an ATM address. It does not add or remove dynamic entries. Removing the static entry for a specified ATM address from an LE ARP table does not release Data Direct VCCs established to that ATM address. However, clearing a static entry clears any fast-cache entries that were created from the MAC address-to-ATM address binding.
Static LE ARP entries are not aged and are not removed automatically.
To remove dynamic entries from the LE ARP table of the LANE client on the specified subinterface, enter the clear lane le-arp command.
This command adds a static entry to the LE ARP table:
ATM(config-if)#lane le-arp 0800.aa00.0101 47.000014155551212f.00.00.0800.200C.1001.01
Use the lane register command to register a LANE client connected by a PVC to the LANE server on the subinterface. To remove a prior entry, use the no form of this command.
lane register vcd mac-addr atm-addr
vcd | Virtual channel descriptor of the Server Direct PVC through which the LANE client is connected to the LANE server. |
mac-addr | MAC address of the LANE client. |
atm-addr | ATM address of the LANE client. |
By default, no PVC is defined, and no MAC address and ATM address are provided.
IOS ATM command.
Interface configuration.
Ordinarily, SVCs are used instead of PVCs for communications within ELANs, and registration occurs dynamically via the LANE protocol. Use the lane register command only when you use PVCs.
If you use PVCs instead of SVCs for Server Direct circuits between the LANE server and LANE clients, use this command on the LANE server to identify the MAC address and the ATM address of the LANE client at the other end of a virtual circuit. If the client at the other end has a different ATM address, it is not allowed to join the ELAN.
Use the lane pvc command on a LANE client and the lane register command on a LANE server to enable PVCs, instead of SVCs alone, for LANE. The vcd value in the lane register command must match the vcd value in a lane pvc command and in an atm pvc command.
If you use PVCs for the Control Direct VCCs, you must also use PVCs for the Control Distribute VCCs. If you use PVCs for the Multicast Send VCCs, you must also use PVCs for the Multicast Forward VCCs.
This example shows how to register a LANE client connected by a PVC to the LANE server on the subinterface:
ATM(config)#int atm0.1
ATM(config-subif)#lane register 98 0800.aa00.0101 47.000014155551212f.00.00.0800.200C.1001.01
ATM(config-subif)#end
Use the lane server-atm-address command to configure the LES ATM address. The no version of this command deletes the specified LES.
lane server-atm-address les_name atm-address-template
les_name | Name of the LES. |
atm-address- template | ATM address or template in which wildcard characters are replaced by any nibble or group of nibbles of the prefix bytes, the ESI bytes, or the selector byte of the automatically assigned ATM address. |
The default is Ethernet.
IOS ATM command.
Interface configuration.
For complete information on using ATM address templates, refer to the "Configuring ATM LANE Emulation" chapter in the Catalyst 5000 Series Software Configuration Guide.
This example shows how to configure the LES ATM address:
ATM(config-if)#lane server-atm-address 39.000000000000014155551211.0800200c1001.00.
ATM(config-if)#
Use the lane server-bus command to configure the LES and BUS for the specified ELAN on the subinterface. The no version of this command deletes the specified LES/BUS.
lane server-bus {ethernet | tokenring} elan_name [elan-id id]
ethernet | Keyword to specify an Ethernet network. |
tokenring | Keyword to specify a Token Ring network. |
elan_name | Name of the ELAN. |
elan-id | (Optional) Keyword to specify the ELAN ID. |
id | ELAN ID of the ELAN. |
The default is Ethernet.
IOS ATM command.
Interface configuration.
The LES/BUS of an ELAN must be collocated.
The maximum length of the elan_name is 32 characters.
If the lane server-bus command has already been entered on the subinterface for a different ELAN, the LES terminates procedures with all LECs and comes up as the LES for the new ELAN.
To participate in MPOA, a LEC must have an ELAN ID. The lane server-bus command enables the LEC to obtain the ELAN ID from the LES when the LEC bypasses the LECS phase.
| Caution If an ELAN ID is supplied, ensure that it corresponds to the same ELAN ID value specified in the LECS for the same ELAN. |
You can also enter the name elan-id command to obtain the ELAN ID from the LECS. The no form of this command removes a previously configured LES/BUS on the subinterface.
This example shows how to enable the LES/BUS for an Ethernet ELAN:
ATM(config-subif)#lane server-bus ethernet default
ATM(config-subif)#end
