RADIUS - Remote Authentication Dial In User Service
RADIUS is a client / server system that secures the LTE against unauthorized access. It is based on open
standard RFCs: RFC 2865/6, 5607, 5080 and 2869. It is used for remote user Authorization, Authentication
and Accounting.
When a user logs into an LTE with RADIUS enabled, the user’s credentials are sent to the RADIUS server for
authentication of the user.
Transactions between the RADIUS client and RADIUS server are authenticated through the use of a shared
secret, which is never sent over the network.
For a RADIUS server to respond to the LTE, it must be configured with the following Management-Privilege-
level attributes:
Admin Level = 4
Technician Level = 2
Viewer Level = 1
Alternatively, for Admin level only, for a RADIUS server to respond to the LTE, it must be configured with
attributes Service-Type (6) = Administrative (6) which will grant the user admin access to the LTE.
A RADIUS server can act as a proxy client to other RADIUS servers or other kinds of authentication servers.
