Configuration	This section provides an overview of the following configuration
Process Overview	information:
	■	Configuration Components
	■	Configuration Defaults
Configuration	ATM Backbone SwitchModule configuration consists of three main
Components	components, described in the following sections:

LAN Emulation Configuration

Defines up to 64 LECs (LAN Emulation Clients) and assigns each to a unique ELAN. LEC configuration also involves defining various ELAN parameters for created LECs.

Initial LEC configuration requirements are specified in Configuring LAN

Emulation Parameters later in this document.

Bridge Configuration

After it is created, a LEC must be assigned to an existing SwitchModule vbridge and can be configured as a normal SwitchModule bridge port, except that the SwitchModule never elects a bridgeport-LEC as master bridge port.

See the CoreBuilder 5000 SwitchModule User Guide for more information on master bridge ports.

Initial bridge configuration requirements are specified in Configuring LAN Emulation Parameters later in this chapter. For a complete list of configurable bridging parameters, see the CoreBuilder 5000 SwitchModule User Guide.
