Parameter
Description
Aging Time
Synopsis:
15 to 800
Default:
300 s
This parameter configures the time that a learned MAC address is held before being
aged out.
Age Upon Link Loss
Synopsis:
{ No, Yes }
Default:
Yes
When set to Yes, all MAC addresses learned on a failed port will be aged-out
immediately upon link failure detection.
When link failure occurs the switch may have some MAC addresses previously learned
on the failed port. As long as those addresses are not aged-out the switch will still be
forwarding traffic to that port, thus preventing that traffic from reaching its destination via
the new network topology.
Note that when a network redundancy protocol, e.g. RSTP/MSTP, is enabled on the
switch, that redundancy protocol may, upon a link failure, flush MAC addresses learned
on the failed port regardless of the setting of this parameter.
