to locally authorize all MAC authentication requests for connecting end‐systems, thereby not requiring a list of known MAC addresses. In fact, Enterasys NAC can be configured in a “learning mode” to dynamically learn the MAC addresses of all devices connecting to the network, permitting network access to all of these end‐systems for a period of time.

After the MAC addresses are learned, NAC can be reconfigured to permit access only to these end‐systems, requiring all other devices connecting to the network to go through a registration process.

With MAC authentication deployed on the network, a backend RADIUS server with associated directory services is not required, simplifying the implementation. Furthermore, because MAC authentication only requires the end‐system to generate an Ethernet packet onto the network, both human‐centric and machine‐centric end‐systems have the capability to authenticate to the network, regardless of whether the end‐system is a PC or a printer.

Case #2: Authentication methods are deployed on the network.

If authentication is currently deployed on the network with 802.1X, web‐based, and/or MAC authentication, then a RADIUS server with associated backend directory services must be deployed for user/device 802.1X and web‐based credential validation. Moreover, if RADIUS authentication for switch management logins is implemented, a RADIUS server must be deployed on the network. In this scenario, out‐of‐band NAC is configured to seamlessly proxy RADIUS authentication requests received from the switches at the intelligent edge of the network to the backend RADIUS server, without requiring complex configuration changes to the RADIUS server and associated directory services. In addition, NAC can also be configured to locally authorize MAC authentication requests.

Overview of Supported Authentication Methods

Following is an overview of authentication methods supported by Enterasys and some third‐party switches, and proxied by out‐of‐band NAC.

802.1X Authentication

The IEEE 802.1X standard for port‐based network access control, provides network administrators with the ability to authenticate and authorize an end user at the port level.

The 802.1X authentication method is usually implemented on PCs in secure environments and requires that the end‐system implement an 802.1X supplicant, which is special software that communicates in this protocol.

Because 802.1X requires the input of user credentials, 802.1X is normally used on user‐centric end‐ systems that have a concept of an associated user, such as a PC. Therefore, this authentication method may be inappropriate for machine‐centric devices, such as printers and IP cameras. However, newer software releases for IP phones may include an 802.1X supplicant.

Since Enterasys NAC only acts as a pass‐through to an upstream RADIUS Server, it is mandatory that a full authentication deployment is configured on the network if 802.1X is used.

Web‐Based Authentication

Web‐based authentication, or Port Web Authentication (PWA), is an authentication process that uses a web browser, user‐login process to gain access to ports. It employs either CHAP (Challenge Handshake Authentication Protocol) or PAP (Password Authentication Protocol).

Since web‐based authentication only requires that a web browser is on the end‐system, it is deployed in heterogeneous environments where certain end‐systems may not have an 802.1X supplicant installed.
