Configuring EAD 177

Networking and As shown in Figure 47, a user host is connected to Ethernet 1/0/1 on the switch. Configuration On the host runs the 802.1x client supporting 3Com EAD extended function. You Requirements are required to configure the switch to use the RADIUS server for remote user

authentication and the security policy server for EAD control of users.

A CAMS server acts as the RADIUS server and another acts as the security policy server.
