Hi, what switches? with Cisco you can use various fallthroughs - and you can ensure that even the non 802.1X clients are catered for.... MAB will allow you to send request to RADIUS server and then its your policy that matters.. eg
eg any MAC address, returns an ACCEPT but with a VLAN attribute. the switch then puts the client on the correct, limited network.... or you can use guest-vlan or fail vlan methods on the switch too... ..are you going via the route of 'if not known, then get a network that send them to a web portal with intructions, install program etc' - or are you dealing with these people individually? alan - List info/subscribe/unsubscribe?
