Default Level

2: System level

Parameters

track-entry-number: Track object ID, in the range 1 to 1024.

interface-type interface-number: Type and number of the interface to be monitored.

Description

Use the track interface command to create a Track object to be associated with the physical status of a specified interface.

Use the undo track command to remove the created Track object.

By default, no Track object to be associated with the physical status of a specified interface is created.

Note that:

l          After a track object is created, you cannot use the track interface command to modify it; you must reconfigure it after deleting the track object.

l          After a track object to be associated with the physical status of a specified interface is created, the status of the track object is Positive if the physical status of the interface is up; the status of the track object is Negative if the physical status of the interface is down. You can use the display ip interface brief command to display the physical status of an interface.
