Bridging

Type

Indicates the type of an entry in the database. The possible types are Static, Dynamic, Learned, Self, or Permanent. You can alter the entry type, as described in the next section.

Source Port

Indicates the index number of the port on which the address entry was first detected. A question mark (?) indicates that the address entry was not a learned entry, but Port Filtering information applies to it (i.e., the entry is a created Permanent, Dynamic, or Static entry and has corresponding filtering information).

Receive Port

Indicates the number of the port on which a frame must be received in order for the entry’s Port Filtering information to apply. An asterisk (*) indicates that the receive port is promiscuous, and filtering parameters will be applied to all packets regardless of their source (assuming no conflicting entry applies). You can change the receive port, as described in the following section.

Port Filtering

Indicates the action that will take place at each bridge port when it receives frames from the selected address entry. A green arrow indicates that the frames received from the address will be forwarded to the port’s associated segment

( ). A red circle indicates that frames will be filtered (blocked) from the port’s

associated segment ( ). You can change the Port Filtering action for Permanent, Static, and Dynamic entry types, as described in the next section. (Note that port filtering is scrollable among all the potential ports; however, only two consecutive ports can be viewed simultaneously.)

Configuring the Filtering Database

You can configure the Filtering Database by:

•Altering the Ageing Time for Dynamic and Learned entries.

•Changing the type of entry with the Type buttons.

•Changing the Receive port for the filter.

•Changing the Port Filtering action at each bridge port.

•Adding or deleting individual Filtering Database entries.

•Clearing all Permanent, Static, or Dynamic entries from the Filtering Database.

Note that although configuration changes will appear in the window, no action actually takes place in the bridge’s Filtering Database until you click on in the bottom right of the window. This saves the new configuration. If you

change the window without clicking , then attempt to exit the window by
