[c-nsp] Ethernet Authentication

[Paul Stewart]

The subject may not be the right description but I'm trying to find a
way to authenticate a bunch of fixed-wireless customers currently...

Here's my scenario:

Remote POP with Cisco 2621 and Cisco 2924 or 2950 switch.  At the remote
POP, Motorola Canopy or Trango fixed wireless customers are connected
into the switch.  The Cisco 2621 provides DHCP to anyone connected as
the Motorola and Trango both do their own proprietary radio
authentication.

The problem is that once the radio authenticates, then the end user
computer gets an IP from the 2621 and they surf.  This is great until
you want to know who is on which IP address etc.  Obviously moving the
customers to PPPOE would work well, but that's a major change especially
on one site where we might have to change 150-180 users at once (our
helpdesk would shoot me lol)

Ideally, what I'd like to know if it's possible is some kind of
authentication via a web browser linked to our existing Radius.  Is
there a way to do this in IOS and/or 3rd party?  I was thinking of 802.x
but all these customers connect across the same ethernet port in most
locations (or a few ports)...

Thanks again to the list for your help...appreciate it...
