About MAC-layer bridge packet filtering
To perform MAC-layer bridging, the switch must know the destination
MAC-layer address of each device on each attached network so it can
forward packets to the appropriate destination. MAC-layer addresses are
stored in the bridging table, and you can filter packet traffic based on the
destination MAC-layer address information.
MAC-layer address of each device on each attached network so it can
forward packets to the appropriate destination. MAC-layer addresses are
stored in the bridging table, and you can filter packet traffic based on the
destination MAC-layer address information.
The MAC filtering supported in the ERS 8300 is the Bridge MIB filtering
(RFC 1493). The number of MAC filters is limited to 100. You create a filter
entry in much the same way as you create a static MAC entry; by entering
a MAC address and the port it resides on. In the MAC filter record, you
also specify the ports for which to discard source or destination packets for
the MAC address on a port.
