Receive Backend Server Counters
For MAC-based ports there are two tables containing backend server counters. The left-most
shows a summary of all backend server counters on this port. The right-most shows backend
server counters for the currently selected client, or dashes if no client is selected or available.
A client can be selected from the list of authorized/unauthorized clients below the two counter
tables.
◆ Access Challenges –
■ 802.1X-based: Counts the number of times that the switch receives the first request from
the backend server following the first response from the supplicant. Indicates that the
backend server has communication with the switch.
■ MAC-based: Counts all Access Challenges received from the backend server for this
port (left-most table) or client (right-most table).
◆ Other Requests –
■ 802.1X-based: Counts the number of times that the switch sends an EAP Request
packet following the first to the supplicant. Indicates that the backend server chose an
EAP-method.
■ MAC-based: Not applicable.
◆ Auth. Successes –
■ 802.1X- and MAC-based: Counts the number of times that the switch receives a success
indication. Indicates that the supplicant/ client has successfully authenticated to the
backend server.
◆ Auth. Failures –
■ 802.1X- and MAC-based: Counts the number of times that the switch receives a failure
message. This indicates that the supplicant/client has not authenticated to the backend
server.
Transmit Backend Server Counters
