Chapter 11 Avaya P330 Layer 2 Features
Intermodule Port Redundancy
The intermodule port redundancy feature supports one pair of redundant ports per stack. The secondary port is activated:
•when the primary port link is down, or
•when the module in the stack holding the primary port has been powered down or removed.
Switching time for intermodule port redundancy is approximately 1 second. Defining intermodule port redundancy on ports with no link causes both ports to be disabled. You should connect the link prior to attempting to define intermodule port redundancy.
Once a port has been designated in a redundancy scheme, either as a primary or a secondary port, it can not be designated in any other redundancy scheme. Intermodule Port Redundancy does not interworks with the Spanning Tree Algorithm.
