— “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.
