3 Repeat steps 1 and 2 for each LEC you require.
4 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.

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.
