Parameters
track-entry-number: Specifies the track entry ID in the range of 1 to 1024.
interface-type interface-number: Specifies an interface by its type and number.

the track entry state has changed. If this keyword is not specified, the Track module notifies the
application modules immediately when the track entry state changes.
negative negative-time: Specifies the amount of time the Track module waits before notifying the
application modules that the state of the track entry has changed to Negative. The negative-time
argument represents the delay time in the range of 1 to 300 seconds.
positive positive-time: Specifies the amount of time the Track module waits before notifying the
application modules that the state of the track entry has changed to Positive. The positive-time argument
represents the delay time in the range of 1 to 300 seconds.
Usage guidelines
When you create a track entry that is associated with the physical state of a specific interface, the state
of the track entry is Positive if the physical state of the interface is up. The state of the track entry is
Negative if the physical state of the interface is down. To display the physical state of an interface, use
the display ip interface brief command.
After a track entry is created, you can only use the track interface delay command to modify its
notification delay settings. To modify other settings, you must delete the entry and create a new one.
