Filter Address

Filter Ethernet packets based on MAC address


To filter network buffer packets by their MAC addresses, use the Filter Address block. See Filter Type and Filter Address Blocks for cautions on setting the parameters for this block.

If you specify one MAC address, one port appears with the name Match. The block directs packets with this MAC address to port Match.

If you specify more than one MAC address, multiple ports appear, matched to the values in parameter MAC Address. The block directs packets with the first address to Match Addr (1), with the second address to Match Addr (2), and so on.


The port count depends on how many MAC addresses appear in parameter MAC Address.

Packets that do not meet the filter criteria appear at this port.


To activate this port, clear Drop non-matches.

Enter a cell array that contains the MAC addresses for the filter.

To discard packets that do not match the filter criteria, select this parameter.

To filter addresses for the source address, clear this check box (default).
