The Port Authentication Settings Page contains the following port authentication parameters:

• Port — Displays a list of interfaces on which port-based authentication is enabled.

• User Name — Displays the supplicant user name.

• Current Port Control — Displays the current port authorization state. The possible field values are:

– Authorized — Indicates the interface is in an authorized state.

– Unauthorized — Denies the selected interface system access.

• Admin Port Control — Indicates the port state. The possible field values are:

– Auto —Enables port-based authentication on the device. The interface moves between an authorized or

unauthorized state based on the authentication exchange between the device and the client.

– ForceAuthorized — Indicates the interface is in an authorized state without being authenticated. The

interface re-sends and receives normal traffic without client port-based authentication.

– ForceUnauthorized — Denies the selected interface system access by moving the interface into

unauthorized state. The device cannot provide authentication services to the client through the interface.

• Enable Guest VLAN — Indicates if the Guest VLAN is enabled. The possible field values are:

– Checked — Enables the Guest VLAN.

– Unchecked — Disables the Guest VLAN. This is the default value.

• Authentication Method — Defines the user authentication methods. MAC authentication ensures that end-

user stations meet security policies criteria, and protects networks from viruses.

To activate MAC authentication first define the following:

1. Enable Guest VLAN.

2. Set the Admin Port Control option to Auto.

The possible values are:

– 802.1X Only – Enables only 802.1X authentication on the device.

– MAC Only — Enables only MAC authentication on the device.

– MAC + 802.1X – Enables MAC Authentication + 802.1X authentication on the device. In case of MAC+

802.1x, 802.1x takes precedence.

• Enable Periodic Reauthentication — Permits port reauthentication. The possible field values are:

– Enable — Enables port reauthentication. This is the default value.

– Disable — Disables port reauthentication.

• Reauthentication Period — Displays the time span (in seconds) in which the selected port is

reauthenticated. The field default is 3600 seconds.

• Reauthenticate Now — Reauthenticates the port immediately.

• Authenticator State — Displays the current authenticator state (as defined in Admin Port Control).

• Quiet Period — Displays the number of seconds that the device remains in the quiet state following a failed

authentication exchange. The possible field range is 0-65535. The field default is 60 seconds.

• Resending EAP — Defines the amount of time (in seconds) that lapses before EAP requests are resent.

The field default is 30 seconds.

• Max EAP Requests — Displays the total amount of EAP requests sent. If a response is not received after the

defined period, the authentication process is restarted. The field default is 2 retries.

• Supplicant Timeout — Displays the amount of time (in seconds) that lapses before EAP requests are resent

to the supplicant. The field default is 30 seconds.

• Server Timeout — Displays the amount of time (in seconds) that lapses before the device re-sends

a request to the authentication server. The field default is 30 seconds.

• Termination Cause — Indicates the reason for which the port authentication was terminated.
