Dell EMC SmartFabric OS10 User Guide Release 10.5.0

You can monitor the state of any interface according to the virtual group. OS10 supports a maximum of 10 track groups and each track group can track only one interface.

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 the priority cost.

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 priority cost of the tracking group must be less than the configured priority of the VRRP group. If you configure the VRRP group as the owner router with a priority 255, tracking for that group is disabled, regardless of the state of the tracked interfaces. The priority of the owner group always remains 255.

For a virtual group, track the status of a configured object using the track command and the object number. You can also configure a tracked object for a VRRP group with this command before you create the tracked object. No changes in the VRRP group’s priority occur until the tracked object is determined to be down.
