Filtering Database 5-25
Bridging
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 applies to all ports of the bridge (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, as described
in the next section. Use the scroll bars to view the filtering/forwarding status for
all available ports; only two consecutive ports are displayed 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 the OK
button in the bottom right of the window. This saves the new configuration. If you
change the window without clicking OK, then attempt to exit the window by
clicking Cancel, a text box will appear stating “Changes have been made. Cancel
them?”. Click on Yes to exit the window without changing the Filtering Database,
or No to return to the window.
NOTE
When you reconfigure the Filtering Database and click OK, the screen will clear
temporarily and a message will appear to indicate that the information is being updated.
When the changes have been successfully set and the Filtering Database has updated, the
screen information will be refreshed.
