Forwarding

The Switch supports MAC forwarding.

MAC Forwarding

The MAC Forwarding feature is divided between MAC Address Aging Time and Configure
The Broadcast Storm Control Mode.
MAC Address Aging Time
The MAC Address Aging Time field 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
765 seconds.
Configure The Broadcast Storm Control Mode
This field can be toggled between Enable and Disable using the drop-down menu. This
enables or disables, globally, the Switch's reaction to Broadcast storms, triggered at the
threshold set in the last field.

Note: A very long Aging Time can result with the out-of-date Dynamic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 too 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.
