Hi all,
We have a DXS-3350SR as our core switch. It has served us well until Windows XP SP3 came around. If a machine with Windows XP Pro (32 or 64bit) with IEEE 802.1x authentication enabled on the network interface is booted or a user login via remote desktop. The CPU load of our DXS-3350SR goes to 100% and it stops forwarding traffic and all link led's blinks simultaneously. We have upgraded to latest fw. with no luck. I think this is a configuration problem so I have attached the 802.1x part from our configuration.
The basic setup of our network is:
3350

5x3024 (With 4x 1Gbit/s trunks)
