Bridge Filtering

Protocol Filtering

What is It?Protocol filtering is used to prevent nodes operating with a certain protocol from operating outside their intended scope. For protocol filtering, the same fundamentals apply as with MAC Address Filtering except the Bridge Link record specifies Protocol Filtering Action.

This table shows how to configure the Bridge Link record for protocol filtering.

Parameter		Values
Entry Number	1	5	6
Protocol Filtering Action	Pass	Pass	Pass

When protocol filtering is performed, the system checks the Bridge Link Table of the bridge link involved with the frame to see if the Protocol Filtering Action parameter is configured to disable all filtering on that bridge link.

Figure 30, which describes the MAC Address filtering process, is also applicable to protocol filtering. For example, if the parameter is configured to disable filtering (NONE selected), then the frame is allowed to pass and no filtering is applied.

The Protocol Filter Table is used with the Bridge Link Table to specify filtering action. It includes the link action parameters used to apply filtering action to every link.
