◆ 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.

◆ The reauthentication time is a global setting and applies to all ports.
◆ When the reauthentication time expires for a secure MAC address it is
reauthenticated with the RADIUS server. During the reauthentication
process traffic through the port remains unaffected.
