Round-Trip Time – The time interval (measured in milliseconds)
between the most recent Access-Reply/Access-Challenge and the
Access-Request that matched it from the RADIUS authentication
server. The granularity of this measurement is 100 ms. A value of 0
ms indicates that there hasn't been round-trip communication with
the server yet.
RADIUS Accounting Statistics
◆ Receive Packets
■
Responses – The number of RADIUS packets (valid or invalid)
received from the server.
■
Malformed Responses – The number of malformed RADIUS
packets received from the server. Malformed packets include
packets with an invalid length. Bad authenticators or unknown
types are not included as malformed access responses.
■
Bad Authenticators – The number of RADIUS packets containing
invalid authenticators received from the server.
■
Unknown Types – The number of RADIUS packets of unknown
types that were received from the server on the accounting port.
■
Packets Dropped – The number of RADIUS packets that were
received from the server on the accounting port and dropped for
some other reason.
◆ Transmit Packets
■
Requests – The number of RADIUS packets sent to the server. This
does not include retransmissions.
■
Retransmissions – The number of RADIUS packets retransmitted
to the RADIUS accounting server.
■
Pending Requests – The number of RADIUS packets destined for
the server that have not yet timed out or received a response. This
variable is incremented when a Request is sent and decremented
due to receipt of a Response, timeout, or retransmission.
■
Timeouts – The number of accounting timeouts to the server. After
a timeout, the client may retry to the same server, send to a
different server, or give up. A retry to the same server is counted as
a retransmit as well as a timeout. A send to a different server is
counted as a Request as well as a timeout.
