◆
Start - The number of EAPOL Start frames that have been received by
the switch.
◆
Logoff - The number of valid EAPOL logoff frames that have been
received by the switch.
◆
Invalid Type - The number of EAPOL frames that have been received
by the switch in which the frame type is not recognized.
◆
Invalid Length - The number of EAPOL frames that have been
received by the switch in which the Packet Body Length field is invalid.
Transmit EAPOL Counters
◆
Total - The number of EAPOL frames of any type that have been
transmitted by the switch.
◆
Request ID - The number of EAP initial request frames that have been
transmitted by the switch.
◆
Requests - The number of valid EAP Request frames (other than initial
request frames) that have been transmitted by the switch.
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.
There are slight differences in the interpretation of the counters between
port- and MAC-based authentication as shown below.
◆
Access Challenges
For port-based authentication, this field counts the number of times
that the switch receives the first request from the backend server
following the first response from the supplicant. It indicates that the
backend server has communications with the switch.
For MAC-based authentication, this field counts all Access Challenges
received from the backend server for this port (left-most table) or client
(right-most table).
◆
Other Requests - For port-based authentication, this field counts the
number of times that the switch sends an EAP Request packet following
the first to the supplicant. It indicates that the backend server chose an
EAP-method. For MAC-based authentication, this field is not applicable.
◆
Auth. Successes - For both port- and MAC-based authentication, this
field counts the number of times that the switch receives a success
indication. It indicates that the supplicant/client has successfully
authenticated to the backend server.
◆
Auth. Failures - For both port-based and MAC-based authentication,
this field 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.
