Interface Configuration
Command Usage
◆
When enabled on a port, the authentication process sends a Password
Authentication Protocol (PAP) request to a configured RADIUS server. The
user name and password are both equal to the MAC address being
authenticated.
◆
On the RADIUS server, PAP user name and passwords must be
configured in the MAC address format XX-XX-XX-XX-XX-XX (all in upper
case).
◆
Authenticated MAC addresses are stored as dynamic entries in the switch
secure MAC address table and are removed when the aging time expires.
The maximum number of secure MAC addresses supported for the switch
system is 1024.
