Usage
Information
Use this command to create an object that tracks the routing state of an IPv4 Layer 2 interface:
● The status of the IPv4 interface is UP only if the Layer 2 status of the interface is UP and the
interface has a valid IP address.
● The Layer 3 status of an IPv4 interface goes DOWN when its Layer 2 status goes down (for a Layer 3
VLAN, all VLAN ports must be down) or the IP address is removed from the routing table.

● show track – display information about tracked objects, including configuration, current state, and
clients which track the object.
● track interface line-protocol – configure object tracking on the line-protocol state of a Layer 2
interface.

Usage
Information
Use this command to create an object that tracks the line-protocol state of a Layer 2 interface by
monitoring its operational status (UP or DOWN).
When the link-level status goes down, the tracked object status is considered to be DOWN; if the link-
level status is up, the tracked object status is considered to be UP.
