Command Usage
The maximum number of MAC addresses per port is 2048, and the maximum
number of secure MAC addresses supported for the switch system is 1024.

Command Mode
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
username and password are both equal to the MAC address being
authenticated.
• On the RADIUS server, PAP username 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’s
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.
• Configured static MAC addresses are added to the secure address table
when seen on a switch port. Static addresses are treated as authenticated
without sending a request to a RADIUS server.
• MAC authentication, 802.1X, and port security cannot be configured together
on the same port. Only one security mechanism can be applied.
• MAC authentication cannot be configured on trunk ports.
