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 congured 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 conguration. 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 conguration 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 conguration of tracked objects in VRRP groups on a specied interface.
EXEC mode or EXEC Privilege mode
show running-config interface interface
Examples of Conguring 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.
