Also to for 'show trace' to show anything, you need to enable tracing ... e.g.
trace add <interface> 50 to trace next 50 packets > -----Original Message----- > From: vpp-dev-boun...@lists.fd.io [mailto:vpp-dev-boun...@lists.fd.io] On > Behalf Of Dave Barach (dbarach) > Sent: Friday, December 1, 2017 12:32 AM > To: Yeddula, Avinash <ayedd...@ciena.com>; vpp-dev@lists.fd.io > Subject: Re: [vpp-dev] Question on node type "VLIB_NODE_TYPE_PROCESS" > > At least for now, process nodes run on the main thread.
