Hi,

If you can check this, that is great. I've no knowledge of this protocol
nor access to the resources you have.

I found this in a customer trace. I also look them over for anomalies,
This was one of them. Maybe I can pick up some more information when I get
on site.

What does ATALK_PS80211 2D-3 for anyway? Is it a device or AP?

Thanx,
Jaap
