The maximum number of MAC addresses per port is 1024, and the
maximum number of secure MAC addresses supported for the switch
system is 1024. When the limit is reached, all new MAC addresses are
treated as authentication failures.

u
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.
u
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).
u
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.
u
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.
u
MAC authentication, 802.1X, and port security cannot be configured
together on the same port. Only one security mechanism can be
applied.
u
MAC authentication cannot be configured on trunk ports.
