if I use a hub to connect multiple hosts to a port of a 802.1x enabled
switch/router, how can I authenticate each of the host/supplicant? Is there
any such solution? In Cisco IOS 12.0 and earlier, the mulit-host mode of 802
.1x, will allow all the hosts to access the network if one of the host can
be authenticated.
What I wanted to do is, even I used a hub, I want each host to be
authenticated individually. Can I achieve such an objective? I know in Ixia
test solution, on one port they can emula

I believe this basic function can be done by most if not all of current
devices.

actually, if you read the 802.1x standard, this function should not be
supported by a switch/router, although it should be supported in wireless
access points. Is there any standard/rfc/draft that can be used to support
this function and extends the standard? the requirement is switches/routers
have to use MAC addresses to identify different supplicants. I didn't see
Cisco has any mode in dot1x to support this kind of function from their
website and from my past experience on the cisco switches.

It's called port-based authentication because 802.1x is originally designed
for wireless access in which a port is a user.
But technically speaking mac-based 802.1x is no difficultier than port-based
802.1x at all. I'm not sure if Cisco's Catalyst switches don't support mac-
based. Even that's the case, I believe the reason being even Catalyst
desktop switches are designed for one port per user. So I guess it's easier
to find mac-based feature on lower-end vendors.
Just googled "mac based 802.1x

I think you need nac which can be .1x based, l2 IP based or l3 IP based

routers

the document says "future firmware release". :P
I think zher is right, currently it may have to work together with NAC to
find a solution. Mac-based 802.1x is still under project planning at vendors
or may have some proprietary solutions not in any standard track yet.
anyway, thanks.

en, you are also right. on cisco swithes, now they support multiple
authentication mode, which is cisco proprietary:
http://www.cisco.com/en/US/products/hw/switches/ps708/products_configuration_
guide_chapter09186a00801dd679.html#wp1032759:
"You can specify multiple authentications so that more than one host can
gain access to an 802.1x port. Multiple authentication is Cisco proprietary
and allows multiple dot1x-hosts on a port; every host is authenticated
separately. "
