Configuring AAA and RADIUS 541
Configure the Request Retransmission Times
If the RADIUS server fails to respond, the router sends the authentication request
packet again periodically. If no RADIUS server response is received after the
configured value of timeout, the authentication request packet needs to be
transmitted again. The user can set the maximum number of times for the request
retransmission, when the number of request retransmission exceed it, the system
will consider the server fails to work normally and set it to dead.
Table 614 Configure the Times of Request Retransmission
By default, the times of request retransmission are three and the number ranges
from 1 to 255.
Configure the Time Interval at Which the Inquiry Packet is Sent
After the first RADIUS server breaks down (due to line failure between NAS and
the server or RADIUS process failure, the system sets this server to "dead", and
periodically queries whether it can work normally or not. If the server is found to
work normally, then after the currently used server breaks down, the system will
automatically uses the first one.
Table 615 Configure the Time Interval for the Inquiry Packet
By default, the inquiry packet is sent at intervals of 5 minutes after the RADIUS
server fails, and the interval ranges from 1 to 255 minutes.
Configure the Time Interval at Which the Real-Time Accounting Packet is
Sent to the RADIUS Server
After a user passes authentication, NAS sends the user's real-time accounting
information to the RADIUS server periodically. If the real-time accounting request
fails, the user is handled according to the
aaa accounting-scheme optional
command. If the
aaa accounting-scheme optional command has been
configured, the user can continue to use the network services, otherwise, NAS
disconnects the user.
Usually, the server sends the accounting packet only according to the access time
and disconnection time. But for higher reliability, the time interval at which the
real-time accounting packet is sent to the RADIUS server can be configured.
