The number of RADIUS Access-Request packets destined for the server that
have not yet timed out or received a response. This variable is incremented
when an Access-Request is sent and decremented due to receipt of an Access-
Accept, Access-Reject, Access-Challenge, timeout, or retransmission.
Timeouts:
The number of authentication 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.
IP Address:
IP address and UDP port for the authentication server in question.
State:
Shows the state of the server. It takes one of the following values:
Disabled:
The selected server is disabled.
Not Ready:
The server is enabled, but IP communication is not yet up and running.
Ready:
The server is enabled, IP communication is up and running, and the
RADIUS module is ready to accept access attempts.
Dead (X seconds left):
Access attempts were made to this server, but it did not reply within the
configured timeout. The server has temporarily been disabled, but will get
re-enabled when the dead-time expires. The number of seconds left before
this occurs is displayed in parentheses. This state is only reachable when
more than one server is enabled.
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.
