RADIUS Global Configuration
The Remote Authorization Dial-In User Service (RADIUS) client on the PowerConnect 6200 Series
switch supports multiple, named RADIUS servers. The RADIUS authentication and accounting server
groups can contain one or more configured authentication servers that share the same RADIUS server
name.
If you configure multiple RADIUS servers with the same RADIUS Server Name, designate one server as
the primary and the other(s) as the backup server(s). The switch attempts to use the primary server first,
and if the primary server does not respond, the switch attempts to use one of the backup servers with the
same RADIUS Server Name.
The software also supports RADIUS Attribute 4, which is the configuration of a NAS-IP Address. The
network access server (NAS) IP address is only used in Access-Request packets.
In some networks, the RADIUS server is responsible for assigning traffic to a particular VLAN. The
RADIUS enhancements include the Authorization Network RADIUS feature that allows the switch to
accept VLAN assignment by the RADIUS server.
The RADIUS server maintains a user database, which contains per-user authentication information.
RADIUS servers provide a centralized authentication method for:
•Telnet Access
• Web Access
• Console to Switch Access
• Access Control Port (802.1x)
