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
The following example shows how to configure tracking using the track command.
DellEMC(conf-if-tf-1/1)#vrrp-group 111
DellEMC(conf-if-tf-1/1-vrid-111)#track twentyFiveGigE 1/2
The following example shows how to verify tracking using the show conf command.
DellEMC(conf-if-tf-1/1-vrid-111)#show conf
