Configuring MAC Address Filters
MAC address filters are used to specify MAC addresses to be excluded from
network access authentication. MAC addresses in a filter are not authenticated by a
RADIUS server when seen on a port, the addresses are immediately added to the
secure MAC address table.
MAC address filters must first be created and assigned a filter ID, then the filter can
be applied to a port interface. Multiple MAC addresses can be included in a filter, but
only one filter can be applied to a port.
Command Attributes
