A line-protocol object only tracks the link-level (UP/DOWN) status of a specified interface. When the linklevel status goes down, the tracked object status is DOWN; if the link-level status is up, the tracked object status is UP. To remove object tracking on a Layer 2 interface, use the no track object-id command. To configure object tracking on the status of a Layer 2 interface, use the following commands. 1. Configure object tracking on the line-protocol state of a Layer 2 interface. CONFIGURATION mode track object-id interface interface line-protocol Valid object IDs are from 1 to 65535. 2. (Optional) Configure the time delay used before communicating a change in the status of a tracked interface. OBJECT TRACKING mode delay {[up seconds] [down seconds]} Valid delay times are from 0 to 180 seconds. The default is 0. 3. (Optional) Identify the tracked object with a text description. OBJECT TRACKING mode description text The text string can be up to 80 characters. 4. (Optional) Display the tracking configuration and the tracked object's status.

You can track the routing status of any of the following Layer 3 interfaces: • For a 1-Gigabit Ethernet: enter gigabitethernet slot/port in the track interface interface command (see Step 1). • For a 10-Gigabit Ethernet interface, enter the keyword TenGigabitEthernet then the slot/port/ subport information. 690 Object Tracking
