•
You must first configure the redundant LES/BUS pairs on subinterfaces for that ELAN.
•
You must then enter the ATM addresses of the redundant LES/BUS pairs into the LECS database for
the ELAN.
To configure the LES/BUS pairs, use the following commands beginning in privileged EXEC mode:
SUMMARY STEPS
1.
ATM# configure terminal
2.
ATM (config)# interface atm0
3.
ATM (config-subif)# lane fssrp
4.
ATM (config-subif)# interface atm 0. subinterface-number
5.
ATM (config-subif)# lane server-bus tokenringelan-name
6.
Repeat Steps 2 and 3 for all LES/BUSs you want to configure on this ATM module.
7.
ATM (config-subif)# Ctrl-Z
8.
ATM# show lane server
DETAILED STEPS
Command or Action
Purpose
Step 1
ATM# configure terminal
Enters global configuration mode.
Step 2
ATM (config)# interface atm0
Specifies the major interface and enters subinterface
configuration mode.
Step 3
ATM (config-subif)# lane fssrp
Enables FSSRP on the major interface
Step 4
ATM (config-subif)# interface atm 0. subinterface-number Specifies the subinterface for the first ELAN.
Step 5
ATM (config-subif)# lane server-bus tokenringelan-name
Enables the LES/BUS for an ELAN on the subinterface
(you cannot configure more than one LES/BUS per
subinterface).
Step 6
Repeat Steps 2 and 3 for all LES/BUSs you want to
configure on this ATM module.
Step 7
ATM (config-subif)# Ctrl-Z
Exits subinterface configuration mode.
Step 8
ATM# show lane server
Verifies the LES/BUS configuration.
Configuring Fast SSRP for Redundant LANE Services
Note
The LES/BUSs are not fully operational until one or more LECs are configured and the LECS database is
configured and bound to the ATM module interface.
This example shows how to specify the LES/BUS for an ELAN and verify the configuration:
ATM# configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
ATM(config)# interface atm0.1
ATM(config-subif)# lane server-bus tokenring default
