Re: Weird Null Packets

["Michael Glenn" <MGlenn () cco state oh us>]

I extracted just the funky packets; otherwise the segment is working fine atm. 
The packets are the same for Wireshark on both a Win7 box and a Linux laptop. Several ports on the switch were tried, 
so they're in there, all right.

What hardware/OS/... are you using to capture these frames ?

Are you also getting good frames using the same setup ??

Wireshark shows the frames as being all zeros with no ethernet address, 
etc. which makes me wonder if these frames are actually really "on the 
wire".

Do do get the same results using an alternate capture program (windump 
for Windows or tcpdump for *nix) ?

The same with an alternate capture platform ? (eg: Windows iso *nix)?
