Setup call to:
47.0091.8100.0000.1111.
1111.1111.1111.1111.1111.00
Using this redundant configuration, if the active interface on switch C8540-1, ATM 1/1/0, fails for any
reason or is shutdown, the calls are released and subsequently setup on the standby interface on switch
C8540-2, ATM 1/1/0. Also, if a failure occurs anywhere along the path of the soft VC that causes the
active destination to become unreachable from the source, the calls are automatically re-routed to the
standby destination interface.

Configuring Redundant Soft VC Destinations

To configure a redundant soft VC destination, follow these steps:
.
Command
Step 1
Switch(config)# atm soft redundancy group
group-name
Switch(atmsoft-red)#
Step 2
Switch(atmsoft-red)# nsap-address nsap-address Configures the NSAP-format ATM end-system
Step 3
Switch(atmsoft-red)# [no] load-balance
Step 4 Switch(atm-soft-red)# exit
Switch(config)#
Step 5 Switch(config)# interface atm card/subcard/port
Switch(config-if)#
Step 6 Switch(config-if)# atm soft redundancy
member group-name {active | standby}
Step 7 Switch(config-if)# end
