RADIUS server must be configured accordingly.
When authentication is complete, the RADIUS server sends a
success or failure indication, which in turn causes the switch to
open up or block traffic for that particular client, using the Port
Security module. Only then will frames from the client be
forwarded on the switch. There are no EAPOL frames involved in
this authentication, and therefore, MAC-based authentication has
nothing to do with the 802.1X standard.
The advantage of MAC-based authentication over port-based
802.1X is that several clients can be connected to the same port
(e.g. through a 3rd party switch or a hub) and still require individual
authentication, and that the clients don't need special supplicant
software to authenticate. The advantage of MAC-based
authentication over 802.1X-based authentication is that the clients
do not need special supplicant software to authenticate. The
disadvantage is that MAC addresses can be spoofed by malicious
users - equipment whose MAC address is a valid RADIUS user
can be used by anyone. Also, only the MD5-Challenge method is
supported. The maximum number of clients that can be attached
to a port can be limited using the Port Security Limit Control
functionality.
Port State
The current state of the port. It can undertake one of the following
values:
Globally Disabled
: NAS is globally disabled.
Link Down
: NAS is globally enabled, but there is no link on the
port.
Authorized
: the port is in Force Authorized or a single-supplicant
mode and the supplicant is authorized.
Unauthorized:
the port is in Force Unauthorized or a single-
supplicant mode and the supplicant is not successfully authorized
by the RADIUS server.
X Auth/Y Unauth
: the port is in a multi-supplicant mode. Currently
X clients are authorized and Y are unauthorized.
Restart
Two buttons are available for each row. The buttons are only
enabled when authentication is globally enabled and the port's
Admin State is in an EAPOL-based or MAC-based mode.
