Selected Counters
This table is visible when the port is one of the following administrative
states: Multi 802.1X or MAC-based Auth.
The table is identical to and is placed next to the Port Counters table, and
will be empty if no MAC address is currently selected. To populate the
table, select one of the attached MAC Addresses from the table.
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 to 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. As long as the backend
server has not successfully authenticated the client, it is
unauthenticated. If an authentication fails for one or the other reason,
the client will remain in the unauthenticated state for Hold Time
seconds (see page 209).
◆ Last Authentication – Shows the date and time of the last
authentication of the client (successful as well as unsuccessful).
