Prerequisites for Implementing Object Tracking
You must be in a user group associated with a task group that includes the proper task IDs. The command
reference guides include the task IDs required for each command. If you suspect user group assignment is
preventing you from using a command, contact your AAA administrator for assistance.
Information about Object Tracking
Object tracking is a mechanism to track an object and to take an action on another object with no relationship
to the tracked objects, based on changes to the properties of the object being tracked.
Each tracked object is identified by a unique name specified on the tracking command-line interface (CLI).
Cisco IOS XR processes then use this name to track a specific object.
The tracking process periodically polls the tracked object and reports any changes to its state in terms of its
being up or down, either immediately or after a delay, as configured by the user.
Multiple objects can also be tracked by means of a list, using a flexible method for combining objects with
Boolean logic. This functionality includes:
•
Boolean AND function—When a tracked list has been assigned a Boolean AND function, each object
defined within a subset must be in an up state, so that the tracked object can also be in the up state.
