30
NOTE:
•
For types of users, the maximum number of transmission attempts multiplied by the RADIUS server
response timeout period must be less than the client connection timeout time and must not exceed 75
seconds. Otherwise, stop-accounting messages cannot be buffered, and the primary/secondary
server switchover cannot take place. For example, the product of the two parameters must be less
than 10 seconds for voice users, and less than 30 seconds for Telnet users because the client
connection timeout period for voice users is 10 seconds and that for Telnet users is 30 seconds.
•
When configuring the maximum number of RADIUS packet transmission attempts and the RADIUS
server response timeout period, be sure to take the number of secondary servers into account. If the
retransmission process takes too much time, the client connection in the access module may be timed
out while the router is trying to find an available server.
•
When a number of secondary servers are configured, the client connections of access modules that
have a short client connection timeout period may still be timed out during initial authentication or
accounting, even if the packet transmission attempt limit and server response timeout period are
configured with small values. In this case, the next authentication or accounting attempt may succeed
because the router has set the state of the unreachable servers to
blocked
and the time for finding a
reachable server is shortened.
•
Be sure to set the server quiet timer properly. Too short a quiet timer may result in frequent
authentication or accounting failures because the router has to repeatedly attempt to communicate
with an unreachable server that is in the
active
state.

Configuring RADIUS accounting-on
The accounting-on feature enables a router to send accounting-on packets to the RADIUS server after it
reboots, making the server log out users who logged in through the router before the reboot. Without
this feature, users who were online before the reboot cannot re-log in after the reboot because the
RADIUS server considers them to already be online.
If a router sends an accounting-on packet to the RADIUS server but receives no response, it resends the
packet to the server at a particular interval for a specified number of times.
