real-time accounting, the device must periodically send real-time accounting packets to the
accounting server for online users.
When you set RADIUS timers, follow these guidelines:
When you configure the maximum number of RADIUS packet transmission attempts and the
RADIUS server response timeout timer, consider the number of secondary servers. If the
retransmission process takes too much time, the client connection in the access module such as the
Telnet module might time out while the device 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 might 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 can
succeed because the device has set the status of the unreachable servers to blocked so time for
finding a reachable server is shortened.
Make sure the server quiet timer is set correctly. Too short a quiet timer might result in frequent
authentication or accounting failures because the device keeps attempting to communicate with an
unreachable server that is in active state.
A short real-time accounting interval helps improve accounting precision but requires many system
resources. When there are 1000 or more users, set the interval to 15 minutes or longer.
To set RADIUS timers:
Step
1.
Enter system view.
2.
Enter RADIUS scheme view.
3.
Set the RADIUS server
response timeout timer.
4.
Set the quiet timer for the
servers.
5.
Set the real-time accounting
timer.
Configuring the accounting-on feature
The accounting-on feature enables the device to send an accounting-on packet to the RADIUS server after
it reboots so the server can log out users who logged in through the device before the reboot. Without this
feature, users who were online before the reboot could not re-log in after the reboot, because the RADIUS
server would consider them already online.
If the device receives no response to the accounting-on packet, it resends the packet to the RADIUS server
at a particular interval for a specified number of times.
The accounting-on feature must work with the HP IMC network management system.
To configure the accounting-on feature for a RADIUS scheme:
Step
1.
Enter system view.
2.
Enter RADIUS scheme
view.
