DELL PC7024 User Manual

RADIUS Commands

Managing and determining the validity of users in a large network can be 

significantly simplified by making use of a single database of accessible 

information supplied by an Authentication Server. These servers commonly 

use the Remote Authentication Dial In User Service (RADIUS) protocol as 

defined by RFC 2865.
RADIUS permits access to a user’s authentication and configuration 

information contained on the server only when requests are received from a 

client that shares an encrypted secret with the server. This secret is never 

transmitted over the network in an attempt to maintain a secure 

environment. Any requests from clients that are not appropriately configured 

with the secret or access from unauthorized devices are silently discarded by 

the server.
RADIUS conforms to a client/server model with secure communications 

using UDP as a transport protocol. It is extremely flexible, supporting a 

variety of methods to authenticate and statistically track users. It is very 

extensible allowing for new methods of authentication to be added without 

disrupting existing network functionality.
PowerConnect supports a RADIUS client in conformance with RFC 2865 and 

accounting functions in conformance with RFC2866. The RADIUS client 

will apply user policies under control of the RADIUS server, e.g. password 

lockout or login time of day restrictions. The RADIUS client supports up to 

32 named authentication and accounting servers.
Table 32-1below indicates the RADIUS attributes supported by various 

PowerConnect switch service. Administrators may configure these attributes 

on the RADIUS server(s) when utilizing the swith RADIUS service.
