To configure the settings by port, click on the hyperlinked port number under the Port
heading, which will display the following table to configure:
Figure 6- 59. 802.1X Authenticator Settings - Modify
This screen allows you to set the following features:
Parameter Description
Configure Port from [ ] to [ ] Enter the port or ports to be set.
AdmCtrlDir:<both>
Sets the administrative-controlled direction to either in or both. If in
is selected, control is only exerted over incoming traffic through the
port you selected in the first field. If both is selected, control is
exerted over both incoming and outgoing traffic through the
controlled port selected in the first field.
PortControl:<
forceUnauthorized
>
This allows you to control the port authorization state. Select
forceAuthorized to disable 802.1X and cause the port to transition
to the authorized state without any authentication exchange
required. This means the port transmits and receives normal traffic
without 802.1X-based authentication of the client. If
forceUnauthorized is selected, the port will remain in the
unauthorized state, ignoring all attempts by the client to
authenticate. The Switch cannot provide authentication services to
the client through the interface. The third option is auto. This
enables 802.1X 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 transitions from down to up, or when an EAPOL-
start frame is received. The Switch then requests the identity of the
client and begins relaying authentication messages between the
client and the authentication server.
