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 congured priority of the VRRP group. If you congure 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 congured object using the track command and the object number. You can also congure 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.
Congure tracking
To track the objects in a VRRP group or on interfaces, use these commands. The sum of all the costs for all tracked interfaces must be less
than the congured priority of the VRRP group.
