The RADIUS screen is used to configure a Remote
Authorization Dial-In User Service (RADIUS) server for user
authentication.
Security > RADIUS
RADIUS servers provide additional security for networks
by providing a centralized authentication method for web
access. Up to eight RADIUS servers can be configured. The
Switch attempts authentication using the listed sequence
of servers. The process ends when a server either approves
or denies access to a user.
IP Address Enter the IP address of the authentication
server.
Priority The server priority. The possible values are 0
to 65535, where 0 is the highest priority. This priority
determines the order in which RADIUS servers are queried
when more than one RADIUS server is configured. The
default priority is 0.
Authentication Port Enter the authentication port. The
authentication port is used to verify the RADIUS server
authentication. The default value is 1812.

seconds the device waits for an answer from the RADIUS
server before retrying the query, or switching to the next

Dead Time Defines the amount of time (minutes) that a
RADIUS server is bypassed for service requests. The range
is 0 to 2000. The default is 0 minutes.

between the device and the RADIUS server. This key must
match the RADIUS encryption.
