Chapter 7: Access Using RADIUS

7.1Introduction to 802.1x

7.1.1 Description

The TACACS+ protocol is the latest generation of TACACS. TACACS is a simple UDP (User Datagram Protocol) based access control protocol originally developed by BBN for the MILNET (Military Network). Later the enhancements were called TACACS+. TACACS+ is a TCP (Transmission Control Protocol) based access control protocol. TCP offers a connection- oriented transport, while UDP offers best-effort delivery making the access authentication reliable.

Remote Authentication Dial-In User Service or RADIUS is a server that has been traditionally used by many Internet Service Providers (ISP) as well as Enterprises to authenticate dial in users. Today, many businesses use the RADIUS server for authenticating users connecting into a network. For example, if a user connects PC into the network, whether the PC should be allowed access or not provides the same issues as to whether or not a dial in user should be allowed access into the network or not. A user has to provide a user name and password for authenticated access. A RADIUS server is well suited for controlling access into a network by managing the users who can access the network on a RADIUS server. Interacting with the server and taking corrective action(s) is not possible on all switches. This capability is provided on the MultiLink ML1200 Managed Field Switch.

RADIUS servers and its uses are also described by one or more RFCs.

7.1.2802.1x Protocol

There are three major components of 802.1x: - Supplicant, Authenticator and Authentication Server (RADIUS Server). In the figure below, the PC acts as the supplicant. The supplicant is an entity being authenticated and desiring access to the services. The switch is the authenticator. The authenticator enforces authentication before allowing
