Filtering Database 2-45

Bridging
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 portÕs associated segment
( ). A red circle indicates that frames will be Þltered (blocked) from the portÕs
associated segment ( ). You can change the Port Filtering action, as described
in the next section. (Note that port Þltering is scrollable among all the potential
ports; however, only two consecutive ports can be viewed simultaneously.)
Configuring the Filtering Database
You can conÞgure the Filtering Database by:
¥ Altering the Aging Time for Dynamic and Learned entries.
¥ Changing the type of entry with the Type buttons.
¥ Changing the Receive port for the Þlter.
¥ 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 conÞguration changes will appear in the window, no action
actually takes place in the bridgeÕs Filtering Database until you click on the OK
button in the bottom right of the window. This saves the new conÞguration.
If you change the window without clicking on OK, then attempt to exit the
window by clicking on Cancel, a text box will appear stating ÒChanges have been
made. Cancel them?Ó. Click on Yes to exit the window without changing the
Filtering Database, or select No to return to the window.
Altering the Aging Time
To alter the Aging Time for Dynamic and Learned entries:
1. Highlight the Aging Time field with the cursor.
2. Type in the new Aging Time (allowable range is 10 to 1,000,000 seconds).
NOTE
When you reconÞgure 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.
