Security > RADIUS > Configuration
This page allows you to configure up to five RADIUS servers.
RADIUS (Remote Authentication Dial In User Service) is a networking protocol that provides centralized access,
authorization and accounting management for computers to connect and use a network service.
Global Configuration: These settings are common for all of the RADIUS servers.
Timeout: Timeout is the number of seconds, in the range 1 to 1000, to wait for a reply from a RADIUS server
before retransmitting the request.
Retransmit: Retransmit is the number of times, in the range 1 to 1000, a RADIUS request is retransmitted to a
server that is not responding. If the server has not responded after the last retransmit it is considered to be dead.
Deadtime: Deadtime, which can be set to a number between 0 to 1440 minutes, is the period during which the
switch will not send new requests to a server that has failed to respond to a previous request. This will stop the
switch from continually trying to contact a server that it has already determined as dead. Setting the Deadtime to
a value greater than 0 (zero) will enable this feature, but only if more than one server has been configured.
Key: The secret key - up to 63 characters long - shared between the RADIUS server and the switch.
NAS-IP-Address (Attribute 4): The IPv4 address to be used as attribute 4 in RADIUS Access-Request packets. If
this field is left blank, the IP address of the outgoing interface is used.
