• Max Users - Set the maximum number of clients supported on the port when MAC-based 802.1X authentication is enabled on the port. The number of users allowed to authenticate per port ranges from 1 to 16. • Termination Cause - Displays the reason for termination. • MAC Authentication Bypass - Enable this feature to provide 802.1x unaware clients controlled access to the network using the MAC address of the device as an identifier. The known and allowable MAC address and corresponding access rights must be configured in the authentication server. MAC Authentication Bypass only works when the port control mode of the port is MAC based. • When supplicants connect to the port, information about that supplicant is displayed in a table below the configuration fields. The supplicant table contains the following information: • Logical Port - The port to which the supplicant is connected. • Supplicant MAC Address - The MAC-address of the supplicant • Authenticator PAE - Current state of the authenticator PAE state machine. Possible values are Initialize, Disconnected, Connecting, Authenticating, Authenticated, Aborting, Held, ForceAuthorized, and ForceUnauthorized. • Backend PAE - Current state of the backend authentication state machine. Possible values are Request, Response, Success, Fail, Timeout, Idle, and Initialize. • VLAN Assigned - The VLAN assigned to the client by the RADIUS server. When VLAN assignments are disabled, the RADIUS server does not assign any VLAN to the port, and this field is set to 0. • VLAN Name - This feature is an extension of the Dot1x Option 81 feature added in PowerConnect Release 2.1. A VLAN name is accepted as an alternative to a number when RADIUS indicates the Tunnel-Private-Group-ID for a supplicant. Because this option is a text string, it can also be used for a VLAN name. To support this feature, ensure that VLAN names are unique. • Username - The username representing the identity of the Supplicant. This field shows the username when the Admin Interface Control is Automode or MAC-based. If the port is Authorized, it shows the username of the current user. If the port is unauthorized it shows the last user that was authenticated successfully. • Filter ID - The Filter Id assigned to the client by the RADIUS server. This field is not applicable when the Filter-Id feature is disabled on the RADIUS server and client. Displaying the Dot1x Authentication Table 1. Open the Dot1x Authentication page. 2.
