Why can't you just add your plugin to run after ethernet-input and enable it
on all physical interfaces so that you can avoid spanning.
For your approach, are you sure you added your node to run after span-input and
correctly placed on a feature-arc?pls run "show vlib graph" it will tell you
where your node is plugged and it will give you clear idea on where your node
is running.

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.sock2.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:=======================
Thank You very much in advance .Awaiting for your reply as early as possible .
