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 by the

switch and removed automatically from the forwarding table. These

addresses are removed due to non-use based on the time period

defined by the Forwarding Table Ag ing Time pa ramete r in the Sw itch

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.

For 10/100 ports, if Auto-negotiation Enable is set to

"No", the Full Duplex and Port Speed parameters can

be configured. For Gigabit Ethernet ports, if Auto-ne-

gotiation Enable is set to "No", the Flow Control En-

able parameter can be configured.

For 10/100 ports, if Auto-negotiation Enable is set to

"Yes", the Full Duplex and Port Speed fields disappear

and the system automatically configures these func-

tions. For Gigabit Ethernet ports, if Auto-negotiation

Enable is set to "Yes", the Flow Control Enable field

disappears and the system automatically configures

this function.
