Sample ATM Backbone SwitchModule Configurations
1-13
The features of the dual-homing/module redundancy configuration
include:
■
Load balancing
LEC support is distributed manually across two ATM Backbone
SwitchModules
■
ATM PHY redundancy
On either ATM Backbone SwitchModule, if the loss of any critical
function is detected, the redundant ATM OC-3 card becomes active
and the primary ATM OC-3 card is disabled.
■
Module redundancy
Using spanning tree parameters, one ATM Backbone SwitchModule
assumes the LEC support of the other ATM Backbone SwitchModule
if the other ATM Backbone SwitchModule fails.
Refer to the
CoreBuilder 5000 SwitchModule User Guide
for
information on Spanning Tree parameters and configuration
information.
