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 ]
  description <desc-text>
