to disable Address Learning is used where the DAC ES connection is
supported from an external switch, such as in a ring/mesh Ethernet network
where protection is provided by an external RSTP switch. To avoid conflict
between the self-learning functions within the DAC ES and external RSTP
switches during path failure situations, the DAC ES capability must be
disabled. Failure to do so means that in the event of an Ethernet path failure,
and subsequent re-direction of traffic by the external switch to an alternate
path, the DAC ES will inhibit re-direction of current/recent traffic until its
address register matures and deletes unused/un-responsive destination
addresses, which may take up to 5 minutes.
