Groups
A RADIUS server is a central server that provides authentication and authorization services for remote users who access a network. It receives authentication requests from RADIUS clients, such as routers, firewalls, or VPNs, verifies the credentials of the user, and returns an authorization decision to the client.
In a RADIUS server group, you must specify the IP address, port number, and shared key of a specified RADIUS server. Other settings, such as the RADIUS user name format and number of times RADIUS request packets are retransmitted, have default values and can be changed based on network requirements.
The RADIUS server group settings such as the RADIUS user name format and shared key must be the same as those on the RADIUS server.
