have a higher bandwidth than its standby link, traf-
fic is not automatically switched back to the main
link when it recovers. Use this field to manually
switch traffic back to the main link.

enable or disable the resilient link pair. Before you
disable a resilient link pair, you must remove
cabling from the ports to avoid creating loops in
your network configuration.
