Interface/object tracking
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 line-protocol state of any interface using the interface command. Enter an interface type and
node/slot/port[:subport] information, or VLAN number:
● ethernet — Physical interface, from 1 to 48
● vlan — VLAN interface, from 1 to 4093
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.
Configure tracking
To track the object in a VRRP group, use the following commands:
1. Assign an object tracking unique ID number in CONFIGURATION mode, from 1 to 500.
track track-id
2. Monitor an interface in Track CONFIGURATION mode.
