Parameter Description
Admin State Administrative state of the VRRP instance. To start the VRRP instance, change
the admin state to UP in the WebUI.
VLAN VLAN on which the VRRP protocol runs.
Tracking Configures a tracking mechanism that modifies a specified value to the
priority after a controller has been the master for the VRRP instance. This
mechanism is used to avoid failing over to a backup master for transient
failures.
Tracking can be based on one of the following:
l Master Up Time: how long the controller has been the master. The
duration is the length of time that the administrator expects will be long
enough that the database gathered in the time is too important to be lost.
This will vary from instance to instance.
l VRRP Master State Priority: the master state of another VRRP.
Tracking can also be based on the interface states of the controller:
l VLAN and Interface: prevents asymmetric routing by tracking multiple
VRRP instances. The priority of the VRRP interface determined by the sub
value can increase or decrease based on the operational and transitional
states of the specified VLAN or Fast Ethernet/Gigabit Ethernet port. When
the VLAN or interface comes up again, the value is restored to the previous
priority level. You can track a combined maximum of 16 interfaces and
VLANs.
NOTE: The tracked VLAN is different from the VRRP VLAN.
For example, you can track an interface that connects to a default gateway. In
this situation, configure the VRRP priority to decrease and trigger a VRRP
master re-election if the interface goes down. This not only prevents network
traffic from being forwarded, but reduces VRRP processing.
