Description
Identity
Shows the identity of the supplicant, as received in the Response Identity
EAPOL frame.
Clicking the link causes the supplicant's EAPOL and back end 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 back end 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. As long as the back end server hasn't
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.
Last Authentication
Shows the date and time of the last authentication of the client (successful
as well as unsuccessful).
