4.6.6 MAC Address Filters
The MAC filtering mechanism provides a way for the users to define rules to allow/deny frames through the bridge based on source MAC address, destination MAC address and/or frame type. When bridge filtering is enabled, each frame is examined against the defined filter rules sequentially, and when a matched is determined, the appropriate filtering action (determined by the access type selected . . . i.e. allow or deny) is performed. The user should note that the MAC filter will only examined frames from interfaces that are part of the bridge itself. Twenty filter rules are supported with MAC filtering. To enable MAC Filters, click Advanced and under Advanced, select MAC Filters. Figure 15 illustrates a typical Bridge filter configuration.
The User Interface for MAC Filter allows the user to add/edit/delete, as well as, enables the filter rules. To add rules, simply define the source MAC address, destination MAC address and frame type with desired filtering type (i.e. allow/deny), and click the “Add” button. The MAC address must be in the
To edit/modify an existing filter rule, select the desired rule created previously from “Add” in the “Edit” select box. The selected filter rule will appear on the top section, as with the “Add” filter rule. Make the desired change to the MAC address, frame type and/or access type, and click “Apply”.
