3.7.13 MAC Filtering (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 each defined filter rules
sequentially. When a match is determined, the appropriate filtering action (determined by the
access type selected i.e. allow or deny) is performed. Please note that the bridge filter will only
examine frames from interfaces, which are part of the bridge itself. Twenty filter rules are
supported with bridge filtering. See
Fig 1-24.
