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. -Sam.

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 .
