For a virtual group, you can track the line-protocol state or the routing status of any of the following
interfaces with the interface interface parameter:
•
For a 10-Gigabit Ethernet interface, enter the keyword TenGigabitEthernet then the slot/port.
•
For a 40-Gigabit Ethernet: enter fortyGigE slot/port.
•
For a port extender 1-Gigabit Ethernet interface, enter the keyword peGigE then the pe-id/stack-
unit-number/port-number.
•
For a VLAN interface, enter the keyword vlan then a number from 1 to 4094.
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. 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
