Associating Track with interface management
The interface management module monitors the link status or network-layer protocol status of the
interface. The interface management module functions as follows when it is associated with a track entry:
•
When the link or network-layer protocol status of the interface changes to up, the interface
management module informs the Track module of the change and the Track module sets the track
entry to Positive.
•
When the link or network-layer protocol status of the interface changes to down, the interface
management module informs the Track module of the change and the Track module sets the track
entry to Negative.
