Network Access (MAC Address Authentication)
– 306 –
Command Usage
Authenticated MAC addresses are stored as dynamic entries in the switchs
secure MAC address table and are removed when the aging time expires. The
address aging time is determined by the mac-address-table aging-time
command.
This parameter applies to authenticated MAC addresses configured by the MAC
Address Authentication process described in this section, as well as to any
secure MAC addresses authenticated by 802.1X, regardless of the 802.1X
Operation Mode (Single-Host, Multi-Host, or MAC-Based authentication as
described on page 278).
The maximum number of secure MAC addresses supported for the switch
system is 1024.

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
