Track an Interface or Object
You can set Dell Networking OS to monitor the state of any interface according to the virtual group.
Each VRRP group can track up to 12 interfaces and up to 20 additional objects, which may affect the priority of the VRRP group. If the
tracked interface goes down, the VRRP group's priority decreases by a default value of 10 (also known as cost). If the tracked interface's
state goes up, the VRRP group's priority increases by 10.
The lowered priority of the VRRP group may trigger an election. As the Master/Backup VRRP routers are selected based on the VRRP
group's priority, tracking features ensure that the best VRRP router is the Master for that group. The sum of all the costs of all the tracked
interfaces must be less than the configured priority on the VRRP group. If the VRRP group is configured as Owner router (priority 255),
tracking for that group is disabled, irrespective of the state of the tracked interfaces. The priority of the owner group always remains at
255.
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 stack/slot/port/subport information.
•
For a 25-Gigabit Ethernet interface, enter the keyword twentyFiveGigE then the stack/slot/port/subport information.
•
For a 40-Gigabit Ethernet interface, enter the keyword fortyGigE then the stack/slot/port[/subport] information.
•
For a 50-Gigabit Ethernet interface, enter the keyword fiftyGigE then the stack/slot/port/subport information.
•
For a 100-Gigabit Ethernet interface, enter the keyword hundredGigE then the stack/slot/port information.
•
For a port channel interface, enter the keywords port-channel then a 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 and the UP or DOWN state of tracked objects, including the client (VRRP group) that is tracking an
object's state.
