Description
The SET FILTER MODE PROTOCOL_ID_TABLE command enables you to set
the mode in which entries in the protocol id table will be used.
Each packet received by the bridge goes through the destination address
filter of the bridging process. If the packet is to be forwarded and the
mode of the protocol ID table is forward or filter, an additional filter
process is applied to all packets.
The Ethernet protocol type of the packet is compared against the contents
of the protocol type ID table. For example, if a match is found and the
mode is forward, then the packet is forwarded and transmitted out the
other port of the Bridge Module. If no match is found and the mode is
forward, the packet is discarded. If a match is found and the mode is filter,
the packet is also discarded. If a match is found and the mode is filter, the
packet is bridged and transmitted out the other port of the bridge.
