    • MAC-based Auth.
  • Selected Counters: The Selected Counters table is visible when the port is in one of the following administrative states:
    • Multi 802.1X

    • MAC-based Auth.

      The table is identical to and is placed next to the Port Counters table. It is empty if no MAC address is currently selected.

  • Attached MAC Addresses
    • Identity: Shows the identity of the supplicant, as received in the Response Identity EAPOL frame. Clicking the link causes the supplicant's EAPOL and Backend Server counters to be shown in the Selected Counters table. If no supplicants are attached, it shows No supplicants attached. This column is not available for MAC-based Auth.
    • MAC Address: For Multi 802.1X, this column holds the MAC address of the attached supplicant. For MAC-based Auth., this column holds the MAC address of the attached client. Clicking the link causes the client's Backend Server counters to be shown in the Selected Counters table. If no clients are attached, it shows No clients attached.
    • VLAN ID: This column holds the VLAN ID that the corresponding client is currently secured through the Port Security module

    • State: The client can either be authenticated or unauthenticated. In the authenticated state, it is allowed to forward frames on the port, and in the unauthenticated state, it is blocked.

      If the backend server hasn't successfully authenticated the client, it is unauthenticated. If an authentication fails for one or the other reason, the client remains in the unauthenticated state for Hold Time seconds.

    • Last Authentication: Shows the date and time of the last authentication of the client (successful and unsuccessful)
