| Web and MAC Authentication are designed for employment on the “edge” of |
| a network to provide |
| networks and the switch itself from unauthorized access. Because neither |
| method requires clients to run any special supplicant software, both are |
| suitable for legacy systems and temporary access situations where introduc- |
| ing supplicant software is not an attractive option. Both methods rely on using |
| a RADIUS server for authentication. This simplifies access security manage- |
| ment by allowing you to control access from a master database in a single |
| server. (You can use up to three RADIUS servers to provide backups in case |
| access to the primary server fails.) It also means the same credentials can be |
| used for authentication, regardless of which switch or switch port is the |
| current access point into the LAN. |
| Web Authentication |
| authenticate users for access to the network. When a user connects to the |
| switch and opens a web browser the switch automatically presents a login |
| page. The user then enters a username and password, which the switch |
| forwards to a RADIUS server for authentication. After authentication, the |
| switch grants access to the secured network. Other than a web browser, the |
| client needs no special supplicant software. |

| network by authenticating devices for access to the network. When a device |
| connects to the switch, either by direct link or through the network, the switch |
| forwards the device’s MAC address to the RADIUS server for authentication. |
| The RADIUS server uses the device MAC address as the username and |
