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
