Tracking the Line Protocol State of an Interface

Perform this task in global configuration mode to track the line protocol state of an interface.
A tracked object is considered up when a line protocol of the interface is up.
After configuring the tracked object, you may associate the interface whose state should be tracked and specify
the number of seconds to wait before the tracking object polls the interface for its state.
SUMMARY STEPS

2. track track-name
3. type line-protocol state
4. interface type interface-path-id
5. exit
6. (Optional) delay {up seconds|down seconds}
7. Use one of the following commands:
