73.5 Backup Group Commands
The commands below describe Backup Group.
73.5.1 backup-group
A backup group defines a set of interfaces so that only one of the interfaces is active at any
given moment. Other interfaces in the group are automatically disabled.
By default, the interface marked as "priority 1" will be activated; if the active interface loses
connectivity, the device attempts to bring up the next interface in the group. As soon as the
higher-priority interface regains connectivity, the lower-priority interface will be disabled.
To associate interfaces with a backup group, use the "backup monitoring group" command
in interface context.
Syntax
backup-group <group-name> [ primary-wan ]
