Entries in the filtering database consist of:

∙MAC Address

These are the addresses that have been learned dynamically by the Multiprotocol Interconnect module as well as fixed addresses that are entered by the user manually.

∙Scope

This field indicates the ports to which this entry applies, that is, the ports that can forward frames to this MAC address. The value of the scope can be a specific port number or all. All learned entries have a scope of all.

∙Disposition

This field specifies the action to be taken when a frame with a destination address matching this MAC address is received. The values for disposition can be a port number to which the frame will be forwarded or flood which means forwarding to all the bridge ports or discard which means the frame is not to be forwarded on any port. Note that disposition for learned entries is the port number on which the station was learned.

In front of each MAC entry there is a sign which has the following meaning:

−Unlearned (+)

This entry was learned but has been aged-out. Aged out entries will not be used for frame forwarding or discarding. They remain in the database to provide historical information about the MAC addresses learned on each port.

−Learned (#)

This entry has been learned automatically by the Multiprotocol Interconnect module.
