User Guidelines
RADIUS servers are keyed by the host name, therefore it is advisable to use
unique server host names.

characteristics:
Server host IP address — 192.168.10.1

Use the radius-server key command to set the authentication and encryption
key for all RADIUS communications between the switch and the RADIUS
server. Use the no form of the command to disable the key.
