I have one laptop connected at 100 mbps to switch 1, a gigabit fibre
link to another switch where I connect a 2nd laptop running iperf at 100
mbps.
Laptop 1 is running iperf using the command "iperf -s -u -w 64k"
while laptop 2 is running "iperf -c 192.168.0.1 -u -b 95M -w 64k -i 1"
The transfer kicks off fine but I then get the following result

Why am i getting this error, when I do the same test with the two laptops
and a cross over cable it completes.
Any ideas, sorry if this has been covered in the past.
Cheers
