RADIUS Commands

Dell Networking N2000/N3000/N4000 Series Switches
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.
Dell Networking 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 34-1below indicates the RADIUS attributes supported by various Dell
Networking switch service. Administrators may configure these attributes on
the RADIUS server(s) when utilizing the switch RADIUS service.
