Set the MAC Address Aging Time and click the
Apply
button. MAC Address Aging Time specifies the length of time a
learned MAC Address will remain in the forwarding table without being accessed (that is, how long a learned MAC
Address is allowed to remain idle). The Aging Time can be set to any value between 10
and 1,000,000 seconds.
NOTE: A very long Aging Time can result with the out-of-date Dynamic Entries
that may cause incorrect packet filtering/forwarding decisions. A very short
aging time may cause entries to be aged out to soon, resulting in a high
percentage of received packets whose source addresses cannot be found in
the address table, in which case the switch will broadcast the packet to all
ports, negating many of the benefits of having a switch.
