Configuring Enhanced Object Tracking Features
This example configures the tracking of an interface line-protocol state and verifies the configuration:
Switch(config)# track 33 interface gigabitethernet 1/0/1 line-protocol
Switch(config-track)# end
Switch# show track 33
Track 33
Interface GigabitEthernet1/0/1 line-protocol
Line protocol is Down (hw down)

Configuring a Tracked List
You can configure a tracked list of objects with a Boolean expression, a weight threshold, or a percentage
threshold. A tracked list contains one or more objects. An object must exist before it can be added to the
tracked list.

tracked list.
•
You configure a Boolean expression to specify calculation by using either “AND” or “OR”
operators.
operators.
•
When you measure the tracked list state by a weight threshold, you assign a weight number to each
object in the tracked list. The state of the tracked list is determined by whether or not the threshold
was met. The state of each object is determined by comparing the total weight of all objects against
a threshold weight for each object.

interface-id ip routing
interface-id ip routing
(Optional) Create a tracking list to track the IP routing state of an interface, and
enter tracking configuration mode. IP-route tracking tracks an IP route in the
routing table and the ability of an interface to route IP packets.

The object-number identifies the tracked object and can be from 1 to 500.

The interface interface-id is the interface being tracked.
