By default, a RADIUS server
is in active state.
The configured server status
cannot be saved to any
configuration file, and can
only be viewed by using the
display radius scheme
command. After the device
restarts, all servers are
restored to the active state.
Enabling the RADIUS server load sharing feature
By default, the device communicates with RADIUS servers based on the server roles. It first attempts
to communicate with the primary server, and, if the primary server is unavailable, it then searches for
the secondary servers in the order they are configured. The first secondary server in active state is
used for communication. In this process, the workload is always placed on the active server.
Use the RADIUS server load sharing feature to dynamically distribute the workload over multiple
servers regardless of their server roles. The device forwards an AAA request to the most appropriate
server of all active servers in the scheme after it compares the weight values and numbers of
currently served users. Specify a weight value for each RADIUS server based on the AAA capacity of
the server. A larger weight value indicates a higher AAA capacity.
In RADIUS server load sharing, once the device sends a start-accounting request to a server for a
user, it forwards all subsequent accounting requests of the user to the same server. If the accounting
server is unreachable, the device returns an accounting failure message rather than searching for
another active accounting server.
