Wireshark · Wireshark-users: [Wireshark-users] Weird Null Packets

["Michael Glenn" <MGlenn@xxxxxxxxxxxxxxx>]

Hi.

 

I'm getting the weirdest packets trickling out of a network segment, and I'm trying to determine if the switch is dying, or if Microsoft has struck again (I've been installing some Win7 PCs on that segment).

 

The packets are pretty-much nothing but a slew of zeroes; Wireshark guessed them to be FibreChannel traffic, but no such hardware on the segment. I'm attaching an extracted packet capture.

 

Anyone seen this before?

 

Thanks.
