There is also a TenGigabitEthernet5/0/1-tx node. Since you Are using DPDK on this interface, that will call: dpdk_interface_tx() from src/plugins/dpdk/device/device.c hth neale From: <vpp-dev-boun...@lists.fd.io> on behalf of Yuliang Li <yuliang...@yale.edu> Date: Wednesday, 1 November 2017 at 05:31 To: "vpp-dev@lists.fd.io" <vpp-dev@lists.fd.io> Subject: [vpp-dev] dpdk output function Hi, Some node is called "TenGigabitEthernet5/0/1-output".
