Hosts the active elected LECS at WKA

Changing the priority of a resilient LECS

You can force the election of a resilient LECS, by placing it on a higher priority level than other resilient LECSes on the network. The higher the priority assigned to a resilient LECS, the better the chances of it winning the election. By default all resilient LECSes when created are assigned a priority of 128.

You can stop a resilient LECS being elected by assigning it a priority of zero. This enables you to configure the LANE services on a switch that is hosting a resilient LECS, without the possibility of the LECS becoming active.

Changing the priority of a LECS will trigger a new election process and the LECS with the highest priority will be elected. If two or more LECSes have the same priority level then the LECS with the higher ATM address will be elected.

Note: If the network is recovering from a failure, the election process is different. The resilient LECS with the highest up-time will remain the active LECS.

This is to minimize network disruption.

Note: If you configure the priority of a resilient LECS to the highest priority (255), this will force the LECS to be elected after a network failure regardless of the LECS up-time.

For information on the commands used to change the priority of a resilient LECS, see Setting priority level for a resilient LECS in Chapter 14 Managing the LECS.
