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.
