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.
L 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.
L 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.
L Intermodule Port Redundancy does not interworks with the Spanning Tree
Algorithm.
