Managing the LECS

You can rig the election of a resilient LECS, by placing it on a higher priority level 
than other LECSes. 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. 
Avaya recommends that you set the priority of one of the resilient LECS to have a 
higher priority than the others. This will ensure that this LECS will be elected as the 
active LECS.
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. 

If the network is recovering from a network 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. 

To change the priority of the local LECS, use the

 

lane lecs priority

 

command:

Command:

M15-155s8:/>lane lecs priority <priority>

Parameters:

<priority>

Indicates the level of priority assigned to the resilient LECS during the 
election process.
0 

- LECS candidate is not available for election.

1 

- Lowest priority that can be assigned to a LECS.

128  - Default priority assigned to a LECS.
255  - Highest priority that can be assigned to a LECS. 
This will guarantee that the LECS will be elected.
