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.

To associate Track with interface management:

Associating Track with
interface management.

Create a track entry, associate it with

the interface management module to
monitor the link 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.

module

Associating Track with VRRP

Associate the Track module with the VRRP group to implement the following actions:

Change the priority of a router according to the status of the uplink. If a fault occurs on the uplink
of the router, the VRRP group is not aware of the uplink failure. If the router is the master, hosts in the

LAN cannot access the external network. This problem can be solved by establishing a Track-VRRP
