All-
Here's some more information on this thread I started related to
Cisco's IP Source Guard feature (with ARP probes) and intermittent

Our network engineers opened a case with Cisco, and Cisco e

Thanks,
Tim

tcpdump: unknown data link type 524288

I'm running hipster, updated a few days ago, illumos-b106467
Our network engineers recently enabled Cisco's IP Source Guard on the
subnet my workstation is on. The IP Source Guard overview is here:
