Bridge Filters
The bridge 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 match 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 bridge filter only examines frames from
interfaces that are part of the bridge itself. Twenty filter rules are supported with
bridge filtering. To enable Bridge Filters, from the Home screen, click Advanced and
under Advanced, select Bridge Filters.
The User Interface for Bridge 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 press the “Add” button. The MAC address must be in a xx-xx-xx-xx-xx-xx format,
with 00-00-00-00-00-00 as “automatically allow”. Blanks can be used in the MAC
address space, and would be considered also as “automatically allow”.
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 top section, as with
the “Add” filter rule. Make the desired change to the MAC address, frame type and/or
access type, and press “Apply”.
The “Enable Bridge Filters” button allows the user to enable or disable bridge filtering.
It can be set/unset during any add/edit/delete operation. It can also be set/unset
independently by just pressing the “Apply” button.
