Bridge Filters
The bridge filtering mechanism provides a way for the users to define rules to
allow or 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 (allow or deny) is
performed. The bridge filter will only examine frames from interfaces which are
part of the bridge itself. Twenty filter rules are supported with bridge filtering.
