RADIUS Configuration
RADIUS servers provide additional security for networks. The RADIUS server maintains a 
user database, which contains per-user authentication information. The switch passes 
information to the configured RADIUS server, which can authenticate a user name and 
password before authorizing use of the network. RADIUS servers provide a centralized 
authentication method for: 
• W
eb Access
• Access Con
trol Port (802.1X)
The RADIUS folder contains links to the following features:

The Current Server IP Address field is blank if no servers are configured (see RADIUS 
Server Configuration o
n page 173). The switch supports up to three configured RADIUS 
servers. If more than one RADIUS servers are configured, the current server is the server 
configured
 as the primary server. If no servers are configured as the primary server, the 
current server is the most recently added RADIUS server.
