3. Configure the following parameters as needed. The parameters are

defined 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:

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.

Force-unauthorized - Places the port in the unauthorized state,
ignoring all attempts by the client to authenticate. The switch cannot
provide authentication services to the client through the interface.

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

Quiet Period.
Sets the number of seconds that the port remains in the quiet state
following a failed authentication exchange with the client. The default
value is 60 seconds. The range is 0 to 65,535 seconds.

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.

Maximum Request.
Sets the maximum number of times that the switch retransmits an EAP
Request packet to the client before it times out the authentication
session. The default value for this parameter is 2 retransmissions. The
range is 1 to 10 retransmissions.
