Associating Track with interface management

The interface management module monitors the physical status, link status, or network-layer protocol status of interfaces. The associated Track and interface management operate as follows:

When the physical, link, or network-layer protocol status of the interface changes to up, the interface management module informs the Track module of the change. The Track module sets the track entry to positive state.
When the physical, link, or network-layer protocol status of the interface changes to down, the interface management module informs the Track module of the change. The Track module sets the track entry to negative state.

To associate Track with interface management:

Step	Command	Remarks
1. Enter system view.	system-view	N/A
2. Create a track entry, associate it with an interface, and enter its view.	Create a track entry, and associate it with the interface management module to monitor the link status of an interface:track track-entry-number interface interface-type interface-number Create a track entry to monitor the physical status of an interface: track track-entry-number interface interface-type interface-number physical Create a track entry to monitor the network-layer protocol status of an interface: track track-entry-number interface interface-type interface-number protocol { ipv4 \| ipv6 }	By default, no track entries exist.
3. Set the delay for notifying the application module of track entry state changes.	delay { negative negative-time \| positive positive-time } *	By default, the Track module notifies the application module immediately when the track entry state changes.
