— “switchback-interval” — the minimum time (in seconds) that the primary

port link has to be up (following failure) before the system switches back to

the primary port. The “none” parameter, if configured, prevents switching

back to the primary.

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.

Note: 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.

Note: 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.

Note: Intermodule Port Redundancy does not interworks with the Spnning Tree

Algorithm.
