Filtering IP/MAC Address Pairs

Packet filtering can also be used to deny network access to clients using a

specified MAC/IP address pair.

Command Usage

• Both the specified source MAC address and source IP address for an

entry must be matched to satisfy the filtering rule. Any packet matching

a specified entry is dropped at the input port.

• To delete an entry for a MAC and IP address pair, you can specify either

the MAC address or both the MAC and IP address.

• To specify a port list, use a hyphen to indicate a range of ports, or a

comma to indicate a group of non-consecutive ports.

• To specify a MAC address use either of the following hexidecimal

formats: xx-xx-xx-xx-xx-xx or xxxxxxxxxxxx
