3Repeat steps 1 and 2 for each LEC you require.

4Assign a unique LES address for each bridgeport LEC on the same module. If a bridgeport LEC has an address configured that is a duplicate of another bridgeport LEC, it never joins the ELAN.

For a complete list of optional DMM LAN Emulation commands and parameters, see the ATM Backbone SwitchModule Command Reference. For descriptions and examples of the LAN Emulation commands, refer to the DMM Commands Guide.

Verifying After Automatic or Manual LEC configuration, use the SHOW Bridgeport-LECBPORT_LEC STATUS command to verify that the bridgeport-LEC is

Status successfully joined to the intended ELAN.

Configuring ATM	If you install a second ATM OC-3 card on your ATM Backbone
OC-3 Card	SwitchModule, use the following procedure to configure the module
Redundancy	for ATM OC-3 card redundancy:
1	Use the following command to designate one of the two ATM OC-3
	cards as the active ATM OC-3 card.
	CB5000> set module <slot>.1 phy_selection <1 or 2>
	The ATM OC-3 card near the top of the ATM Backbone SwitchModule
	is 1. The lower ATM OC-3 card is 2.
	The ATM OC-3 card you do not make active becomes the redundant
	ATM OC-3 card.
2	Use the following command to enable the ATM Backbone
	SwitchModule to automatically make the redundant ATM OC-3 card
	active if the primary ATM OC-3 card fails (or performance degrades
	significantly):
