Displaying Tracked Objects

To display the currently configured objects used to track Layer 2 and Layer 3 interfaces, and IPv4 and IPv6 routes, use the following show commands.

To display the configuration and status of currently tracked Layer 2 or Layer 3 interfaces, IPv4 or IPv6 routes, or a VRF instance, use the show track command. You can also display the currently configured per-protocol resolution values used to scale route metrics when tracking metric thresholds.
  • Display the configuration and status of currently tracked Layer 2 or Layer 3 interfaces, IPv4 or IPv6 routes, and a VRF instance.
    show track [object-id [brief] | interface [brief] [vrf vrf-name] | ip route [brief] [vrf vrf-name] | resolution | vrf vrf-name [brief] | brief]
  • Use the show running-config track command to display the tracking configuration of a specified object or all objects that are currently configured on the router.
    show running-config track [object-id]
