Configuring the Forwarding Table
The Forwarding Table allows you to designate forwarding treatment
through the switch for specific MAC addresses, allowing you to maintain
the efficiency and security of your network. You can search for specific
MAC addresses by the address itself or by port num ber. The switc h learns
addresses dynamically from incoming p ackets and bu ilds a table of th ese
addresses along with their associated ports. There are three types of
MAC addresses in the forwarding table:
•Dynamic MAC addresses, which are dynamically learned and
removed by the switch based on a time period defined using the
Forwarding Table Aging Time option in the Switch Configuration
Menu.
•Static MAC addresses, which are entered manually, stored in
nonvolatile memory and automatical ly plac ed i n the forw arding tab le.
•System MAC addresses, which are set by the system software and
cannot be modified. Each switch port has a permanent system MAC
address assigned to it.
There are three types of dispos itions a ssoc iated w ith each a ddres s in the
forwarding table:
•Forward, which directs packets destined for a specific MAC address
to a specific port.
•Discard, which drops packets destined for a specific MAC address
(and thus provides a security function by blocking certain packets).
•Local, which is for packets destined for the switch itself (such as a
“local” SNMP management packet).
To configure the forwarding table, do the following:
1. Select Switch Configuration Menu from the Main Menu.
2. Select Forwarding Table Configuration Menu.
If Auto-negotiation Enable is set to No, the Full Duplex
and Port Speed modes need to be configured.
If Auto-negotiation Enable is set to Yes, the Full Duplex
and Port Speed fields disappear and the system auto-
matically configures these functions.
