Repeat steps 1 and 2 for each LEC you require.

Assign 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.

Verifying
Bridgeport-LEC
Status
After Automatic or Manual LEC configuration, use the SHOW
BPORT_LEC STATUS command to verify that the bridgeport-LEC is
successfully joined to the intended ELAN.
Configuring ATM
OC-3 Card
Redundancy
If you install a second ATM OC-3 card on your ATM Backbone
SwitchModule, use the following procedure to configure the module
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):
CB5000> set module <slot>.1 phy_automatic_failover enable
