Enabling Sending Trap Message When A Radius Server Goes Down - H3C S5600 Series Operation Manual

Operation Manual – AAA
H3C S5600 Series Ethernet Switches
For the primary and secondary servers (authentication/authorization servers, or
accounting servers) in a RADIUS scheme:
When the switch fails to communicate with the primary server due to some server
trouble, the switch will turn to the secondary server and exchange messages with the
secondary server.
After the primary server remains in the block state for a specific time (set by the timer
quiet command), the switch will try to communicate with the primary server again when
it has a RADIUS request. If it finds that the primary server has recovered, the switch
immediately restores the communication with the primary server instead of
communicating with the secondary server, and at the same time restores the status of
the primary server to active while keeping the status of the secondary server
unchanged.
To control the interval at which users are charged in real time, you can set the real-time
accounting interval. After the setting, the switch periodically sends online users'
accounting information to RADIUS server at the set interval.
Follow these steps to set timers for RADIUS servers:
Enter system view
Create a RADIUS scheme
and enter its view
Set the response timeout
time of RADIUS servers
Set the time that the
switch waits before it try to
re-communicate with
primary server and
restore the status of the
primary server to active
Set the real-time
accounting interval
