Tracking an Interface To track an interface, use the following commands. NOTE: The sum of all the costs for all tracked interfaces must be less than the configured priority of the VRRP group. • Monitor an interface and, optionally, set a value to be subtracted from the interface's VRRP group priority. INTERFACE-VRID mode track interface [priority-cost cost] The cost range is from 1 to 254. The default is 10. • (Optional) Display the configuration. Display the UP or DOWN state of tracked objects, including the client (VRRP group) that is tracking an object's state. EXEC mode or EXEC Privilege mode show track • (Optional) Display the configuration and the UP or DOWN state of tracked interfaces and objects in VRRP groups, including the time since the last change in an object's state. EXEC mode or EXEC Privilege mode show vrrp • (Optional) Display the configuration of tracked objects in VRRP groups on a specified interface. EXEC mode or EXEC Privilege mode show running-config interface interface Examples of Configuring and Viewing the track Command Dell(conf-if-te-1/1/1)#vrrp-group 111 Dell(conf-if-te-1/1/1-vrid-111)#track Tengigabitethernet 1/2/1 The following example shows how to verify tracking using the show conf command.
