Command Usage
◆ Specified addresses are exempt from network access authentication.
◆ This command is different from configuring static addresses with the mac-
address-table static command in that it allows you configure a range of
addresses when using a mask, and then to assign these addresses to one or
more ports with the network-access port-mac-filter command.
◆ Up to 64 filter tables can be defined.
◆ There is no limitation on the number of entries that can entered in a filter table.
Example
Console(config)#network-access mac-filter 1 mac-address 11-22-33-44-55-66
Console(config)#
