3. Type P to select Port No .
The following prompt is displayed:
Enter port number>
4. Enter the number of the port on the switch you want to configure. You
can configure only one port at a time.
The Port Based Access Control Configuration Menu is updated with
the current settings of the selected port.
5. Configure the 802.1x settings for the port. A change to a parameter
takes affect immediately on the port. The settings are described here:
NAS ID .
This parameter assigns an 802.1x identifier to the switch that applies
to all ports. The NAS ID can be up to sixteen characters. Valid
characters are 0 to 9, a to z, and A to Z. Spaces are allowed.
Specifying an NAS ID is optional.
Port Status.
Displays the current 802.1 status of the port as either authorized or
unauthorized. This is not an adjustable parameter.
Port Control.
Sets the 802.1x port control setting. The possible settings are:
A (Auto) - Enables 802.1x port-based authentication and causes the
port to begin in the unauthorized state, allowing only EAPOL frames to
be sent and received through the port. The authentication process
begins when the link state of the port changes or the port receives an
EAPOL-Start packet from a supplicant. The switch requests the identity
of the client and begins relaying authentication prompts between the
client and the authentication server.
U (Force-unauthorized) - Causes the port to remain in the
unauthorized state, ignoring all attempts by the client to authenticate.
F (Force-authorized) - Disables IEEE 802.1x port-based authentication
and causes the port to transition to the authorized state without any
authentication exchange required. The port transmits and receives
normal traffic without 802.1x-based authentication of the client. This is
the default setting.
Transmission Period .
Sets the number of seconds that the switch waits for a response to an
EAP-request/identity frame from the client before retransmitting the
request. The default value is 30 seconds. The range is 1 to 65,535
seconds.
