Purpose
Enters interface configuration mode for the
interface for which you want to configure backup.
The example shows configuration of a backup
interface for an ATM WAN connection.
Assigns an interface as the secondary or backup
interface.
This can be a serial interface or an asynchronous
interface. For example, a serial 1 interface could
be configured to back up a serial 0/2/1 interface.
The example shows a BRI interface configured as
the backup interface for the ATM 0/0/0 interface.
Specifies the delay between the physical interface
going down and the backup interface being
enabled, and the delay between the physical
interface coming back up and the backup interface
being disabled.
Exits configuration interface mode.
