Users Guide

For a virtual group, you can also track the status of a configured object (the track object-id command) by entering its
object number.
NOTE: You can configure a tracked object for a VRRP group (using the track object-id command in INTERFACE-VRID
mode) before you actually create the tracked object (using a track object-id command in CONFIGURATION mode).
However, no changes in the VRRP group’s priority occur until the tracked object is defined and determined to be down.
In addition, if you configure a VRRP group on an interface that belongs to a VRF instance and later configure object tracking on
an interface for the VRRP group, the tracked interface must belong to the VRF instance.
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 and 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
The following example shows how to configure tracking using 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.
Dell(conf-if-te-1/1/1-vrid-111)#show conf
