Managing the LECS
This chapter describes how to use the command-line interface to manage the LECS
in the Avaya M770 ATM Switch. For information about how to access and use the
Avaya M770 ATM Switch command-line interface, see Chapter 3, “How to Use the
Command-line Interface”.

LECS Location
Any ATM network using LANE must have one active LECS that acts as a central
coordinator, making sure that all LECs join the correct ELANs, even though there
may be a number of resilient (standby) LECS.
Each ATM module can host the LECS locally or look for a remote LECS. A remote
LECS can be in another module, switch, or in an end-station such as a NetWare
server.
The LECS type can be configured as a:

The LECS type can be configured as a:
•
Local Simple LECS
This will force all local LECs to use the local LECS in the M770 ATM Switch.
This will force all local LECs to use the local LECS in the M770 ATM Switch.
•
Local Resilient LECS
This resilient LECS will enter the election and will need to be elected to become
the active elected LECS. If the resilient LECS is not elected, it will become a
standby LECS. For more information about the election process, see Proprietary
resilient LECS in Chapter 13, “LANE Services”.

Remote LECS
This will force all local LECs to use a remote LECS in the network.
This will force all local LECs to use a remote LECS in the network.
Advertised address of a LECS
You can specify the address that the LECS will be advertising. By default on the
M770 ATM Switch the management LEC and LES/BUS will seek a remote LECS at
the WKA.
For information on how to change the location of the LECS, see Changing the
location of the LECS later in this chapter.
