Specified addresses are exempt from network access authentication.
•
This command is different from configuring static addresses with the
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.
