RADIUS Commands 32 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 switch RADIUS service. Table 32-1.
