Configuring Persistent Backup Settings for a Primary

Connection

Even though you install a backup module in a specific module slot, the
corresponding backup line can provide redundancy for any of the WAN
connections on the router. You enable backup for a connection by configuring
a backup dial list on the primary connection's logical interface.
For the primary logical interface, you must configure:
backup call mode
a backup dial list:
• peer's number
• the type of backup connection
• backup interface
You can also configure:
times at which backup support is enabled
backup intervals and timers

Accessing the Primary Connection's Logical Interface

Move to the logical interface associated with the primary connection to access
the backup commands.
Syntax: interface <interface ID>
You can configure backup for these interfaces:
PPP interfaces
Frame Relay subinterfaces
ATM subinterfaces
HDLC interfaces
tunnel interfaces
For example, if the logical interface for the primary connection is Frame Relay
1.101, enter:
ProCurve(config)# int fr 1.101
