Tracking the Line Protocol State of an Interface
Purpose
Enters track configuration mode.
• track-name—Specifies a name for the object to be tracked.
Creates a track based on the line protocol of an interface.
Specifies the interface to track the protocol state.
• type—Specifies the interface type. For more information,
use the question mark (?) online help function.
• interface-path-id—Identifies a physical interface or a virtual
interface.
Use the show interfaces command to see a list of all
Note
possible interfaces currently configured on the router.
The loopback and null interfaces are always in the up
Note
state and, therefore, cannot be tracked.
Exits the track line protocol configuration mode.
(Optional)
Schedules the delay that can occur between tracking whether the
object is up or down.
Saves configuration changes.
• When you issue the end command, the system prompts you
to commit changes:
Uncommitted changes found, commit them
before exiting(yes/no/cancel)?
[cancel]:
◦ Entering yes saves configuration changes to the
running configuration file, exits the configuration
session, and returns the router to EXEC mode.
