Configuring ATM OC-3 Card Redundancy 3-9

2Save the settings as follows:

CB5000> save all

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):

CB5000> set module <slot>.1 phy_automatic_failover enable
