Associating Track with interface management
The interface management module monitors the physical 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 physical 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 physical 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.

2. Associating Track
with interface
management.
• Create a track entry, associate it with the interface
management module to monitor the physical status of
an interface, and specify the delay time for the Track
module to notify the associated application module
when the track entry status changes:
track track-entry-number interface interface-type
interface-number [ delay { negative negative-time |
positive positive-time } * ]
• Create a track entry, associate it with the interface
management module to monitor the Layer 3 protocol
status of an interface, and specify the delay time for the
Track module to notify the associated application
module when the track entry status changes:
track track-entry-number interface interface-type
interface-number protocol { ipv4 | ipv6 } [ delay
{ negative negative-time | positive positive-time } * ]
Use either method.
No track entry is
created by default.
