Configuring Switch-to-RADIUS-Server Communication

A RADIUS security server is identified by its host name or IP address, host name and specific UDP port number, or IP address
and specific UDP port numbers. The combination of the IP address and UDP port number creates a unique identifier, which
enables RADIUS requests to be sent to multiple UDP ports on a server at the same IP address. If two different host entries on
the same RADIUS server are configured for the same service (for example, authentication), the second host entry configured
acts as the failover backup to the first one. The RADIUS host entries are tried in the order they were configured.
