Figure 7-10 Redundant Soft PVC Destinations, Two Switch Example

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

Purpose

Step 1

Switch(config)# atm soft redundancy group
group-name
Switch(atmsoft-red)#

Configures a soft VC redundancy group and
changes to ATM soft VC redundant configuration
mode.

Step 2

Switch(atmsoft-red)# nsap-address nsap-address Configures the NSAP-format ATM end-system

address of an ATM interface.

Step 3

Switch(atmsoft-red)# [no] load-balance

Configures load balancing on a soft VC
redundancy group.

Step 4

Switch(atm-soft-red)# exit
Switch(config)#

Switches back to Global command mode.

Step 5

Switch(config)# interface atm card/subcard/port
Switch(config-if)#

Selects the interface, on the terminating switch,
being configured.

Step 6

Switch(config-if)# atm soft redundancy
member group-name {active | standby}

Creates the redundant soft VC destination.

Step 7

Switch(config-if)# end

Switches to EXEC command mode.
