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 switch 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:
n Master Up Time: how long the switch 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.
n VRRP Master State Priority: the master state of another VRRP.
Tracking can also be based on the interface states of the switch:
n 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.
