AAA and RADIUS Protocol Configuration 287
You can use the following command to set a real-time accounting interval.
Perform the following configurations in RADIUS Scheme View.
Tab le 329 Setting a Real-time Accounting Interval
minute
specifies the real-time accounting interval in minutes. The value should be
a multiple of 3.
The value of
minute
is related to the performance of NAS and RADIUS server. The
smaller the value, the higher the performances of NAS and RADIUS that are
required. When there are a large amount of users (more than 1000, inclusive),
3Com suggests a larger value. The following table recommends the ratio of
minute
value to the number of users.
Tab le 330 Recommended Ratio of Minute to Number of Users
By default,
minute
is set to 12 minutes.
Configure the RADIUS Server Response Timer
If the NAS receives no response from the RADIUS server after sending a RADIUS
request (authentication/authorization or accounting request) for a period of time,
the NAS resends the request, thus ensuring the user can obtain the RADIUS
service. You can specify this period by setting the RADIUS server response timeout
timer, taking into consideration the network condition and the desired system
performance.
Perform the following configurations in RADIUS Scheme View.
Tab le 331 Configure the RADIUS Server Response Timer
By default, the response timeout timer for the RADIUS server is set to three
seconds.
Displaying and
Debugging AAA and
RADIUS Protocol
After the above configuration, execute the display command in any view to
display the running of the AAA and RADIUS configuration, and to verify the effect
of the configuration. Execute the
reset command in User View to reset AAA and
RADIUS statistics. Execute the
debugging command in User View to debug AAA
and RADIUS.
