Glad you are still around, Chuck... :)
The bug being referred to has to deal with the Catalyst 5500 switches, and
early EARL versions...
http://www.cisco.com/warp/public/707/cat5k-8021x-vuln-pub.shtml
Basically, if you are going to roll out XP, you should be using the resource
kit, and configuring the networking of the workstations to disable the
802.1X authentication en-masse...
HTH,

I'm sure you've had your fair share of smart remarks by now. So I won't add
my own. I will remark that in fairness to your boss, there is probably
something he has heard or read which caused him to look for reassurance.
for example, is there a concern with VPN compatibility of operation using
Win XP VPN client software? is there a security concern based upon published
writings about the XP TCP stack?
if the question is "will Cisco routers pass traffic generated by XP
machines?" the answer is "sure. why not" after all, there is nothing in an
IP or a TCP header that indicates the type of host OS that originates the
packet. as long as the traffic is contained in valid packets, the router
will pass process them. knowing that, may I recommend you sit down with the
boss and ask what his concerns are. what has he read? what has he heard? why
would he think there is reason to be concerned? hell, he could be a victim
of MBBW ( Management By Business Week - where the president of the company
saw something in Business Week Magazine over the weekend and on Monday
morning told your boss to investigate and come back with report. ;->
( and yes, I know some bosses are "she" )

Guys,
After my boss delegated me to research all I can about what is need to
upgrade if necessary our Cisco routers and switches to work with Windows-XP,
I was only able to assert from information on the web that there is a bug in
the switch software that is incompatible with XP.
Does anyone here know of any valuable information that can help me with
compiling an educated assessment of this research? Is anyone out there
knowledgeable of this issue either from personal experience or from
literature? I would really appreciate some feedback.
The only problems that I have actually heard of thus far is that which
occurred during the beta test that brought down one of Xerox's network. I
understand that there is a patch that is available as a fix, in addition to
the option of upgrading the Switch code. My question is: -
a). Does the incompatibility only exist with the Switch software or with the
router IOS as
well?
b). Is the patch the best way of dealing with the problem?
I appreciate any help that I can get. Thanks
