Setting the Status of RADIUS Servers
When a primary server fails, the device automatically tries to communicate with the secondary server.
When both the primary and secondary servers are available, the device sends request packets to the
primary server.
Once the primary server fails, the primary server turns into the state of block, and the device turns to
the secondary server. In this case:
z
If the secondary server is available, the device triggers the primary server quiet timer. After the
quiet timer times out, the status of the primary server is active again and the status of the
secondary server remains the same.
z
If the secondary server fails, the device restores the status of the primary server to active
immediately.
If the primary server has resumed, the device turns to use the primary server and stops communicating
with the secondary server. After accounting starts, the communication between the client and the
secondary server remains unchanged.
