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.

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.

Altering the Ageing Time

To alter the Ageing Time for Dynamic and Learned entries:

1.Highlight the Ageing Time field with the cursor.

2.Type in the new Ageing Time (allowable range is 10 to 1,000,000 seconds; the default is 300 seconds).

Changing the Type of Entry

You can change any entry type from its current type (Learned, Self, Permanent, Static, or Dynamic) to either a Permanent, Static, or Dynamic entry. When you have changed the entry type, the Receive Port and Port Filtering fields will be activated so that you can change the filtering information for the entry.

To do change the type of entry in the Filtering Database:

1.Scroll through the address list until the entry appears for which you want to define filtering information.

2.Click on the shadowed Type button. A pull-down menu will appear with the three possible types to which the entry can be changed.

3.Highlight the desired type: Permanent (if you want the filtering information stored in the device’s battery-backed RAM so that it remains even on shut down and power-up of the device), Static (if you want the filtering information only to be active until the device is shut down), or Dynamic (if you want the filtering information to be active only for the duration of the Ageing Timer).

Changing the Receive Port

You can change the Receive port of a Static, Permanent, or Dynamic address entry in the scrollable panel, so that a frame must be received at a specified port for the filtering action to apply. To do so, click on the Receive port in the panel. With each click, the Receive port will cycle to the next port (e.g., from promiscuous — *, to 1, to 2, to 3, to 4, to 5, and so on till the end of the interface stack, and then back to *).
