status of the interface.
Track availability for WAN tracks Layer 3 reachability for WAN
circuits. If there is a transport issue causing middle mile failure, using
track availability for WANs, an HA switchover can be induced by
lowering the priority of the active device.
A maximum of four interfaces can be tracked for availability.
Only WAN facing interfaces with an attached circuit label are
listed for tracking Layer 3 reachability on the WAN.

3 reachability over the WAN circuits is down.
The device is added to the HA Group. An up arrow indicates
that the device is enabled.
The HA switchover from active to backup device
occurs when the track availability fails. As soon as the interface
is available again or when the Layer 3 reachability on the WAN is
restored, an HA switchover is induced restoring the devices to their
