Filtering Frames by a Specific MAC Address
A switch examines frames and sends them through the internetwork according to the destination address;
a switch does not forward a frame back to its originating network segment. You can use the software to
configure specific administrative filters that filter frames based on information other than the paths to
their destinations.
You can filter frames with a particular MAC-layer station destination address. Any number of addresses
can be configured in the system without a performance penalty.
Follow the steps below to filter by the MAC-layer address.
