Chapter 13 LANE Services

Proprietary resilient LECS

The proprietary resilient LECS provides automatic redundancy for the active LECS, by continuously monitoring the status of all resilient LECS.

From the list of available resilient LECSes on the network, the selection of the “active LECS” is done by a process of election. To carry out this election, all ATM switches must be M770s, and ILMI between them must be enabled.

Note: If you are not planning to use PNNI routing or want the switches in the third party environments to host resilient LECS, then you should contact Avaya Technical Support. They can provide you with further information on what manual configuration is required, depending on your third party switch, to get LECS redundancy on your M770 ATM Switches.

A proprietary protocol is used to provide automatic LECS redundancy with the following method of:

establishing an active mesh of SVCs between the switches hosting resilient LECSes.

discovering and advertising resilient LECSes on the network.

propagating the address of the “active LECS” and of the resilient standby LECSes.

Note: To ensure that a standby LECS can smoothly take over the running of the network, should the active elected LECS fail, it must be configured with the same LANE services information as the active elected LECS.

There is no checking of database consistency between switches that are hosting resilient LECSes.

The status of the elected active LECS is continually monitored by the other resilient LECS. Should the elected active LECS fail, another election process will take place to elect a new active LECS from one of the resilient LECSes. Providing all resilient LECS have the same database configurations then there should be no disruption in the working of LANE services in the ATM network.

If your switch is hosting a local LECS then you can view the details of other resilient LECS on the network. For more information about displaying details of other resilient LECS on the network, see Displaying a resilient LECS election candidate in Chapter 14 Managing the LECS.

The example below shows the M770 ATM Switch across a third party switch. It is recommended that if you have a M770 ATM Switch connected via a third party switch, then that M770 ATM Switch should not host a resilient LECS.
