Does “show interface VirtualEthernet0/0/0 features” show your output feature?
You might try “trace add dpdk-input 10” and “show trace” to see what’s
happening to packet received on GigabitEthernet0/8/0.
The story about debug messages not appearing makes me wonder if you’re actually
running the code that you think you’re running.
Try running vpp manually: “.../build-root/build-vpp_debug_native/vpp unix
interactive” and see if your message appear. If not, work out what’s going on
before you do anything else...

Subject: [vpp-dev] VPP New plugin intergation
Hi Team,
We are trying to implement a plugin to process all packets on virtual
interface.
We are doing span from physical interface to virtual interface on vpp,by
running plugin arc node with interface-output.
We are facing some problems.
Could you please help us to resolve the issue by giving your valuable
inputs/suggestions in this regard?.
Steps:
=====
1. Creating virtual interface
cmd: create vhost-user socket /var/run/vpp/vhost1.sock
2.Spanning packet received from physical interface to virtual interface
cmd: set interface span GigabitEthernet0/8/0 destination
VirtualEthernet0/0/0 both
3.Enable my plugin to process all packets on virtual interface.
cmd:myplugin enable-disable VirtualEthernet0/0/0
Problems:
========
1. Couldn't receive packets from virtual interface using myplugin(while
mirroring from physical interface).
2.For debugging in VPP nodes ,tried to add clib
messages(clib_warning,clib_unix_warning,clib_error,clib_unix_error) using
library but we couldn't get any debug message. Even we didn't get debug
messages from dpdk-input and ethernet-input nodes.
3. In general , in VPP , how to enable to debug each node ?
4. Any input /document related to virtual interface packet processing ?
VPP version:
==========
20.01-rc0~519-g669f4e341
Our plugin implementation:
