All:
As of some version of 18.x. (18.3.5, 18.4.302.), tcpdump started being run with the -p flag.
This definitely wasn't the case on 17.2.8 or 16.2.10.
That basically makes it useless for 90% of WAN troubleshooting scenarios.
Is this a mistake that got left in during a debug build? Any way to work around it?
