265. Sample Application Tests: Basic Forwarding/Skeleton Application

The Basic Forwarding sample application is a simple skeleton example of a forwarding application.

It is intended as a demonstration of the basic components of a DPDK forwarding application. For more detailed implementations see the L2 and L3 forwarding sample applications.

265.1. Build DPDK and example skeleton

cd dpdk CC=gcc meson –werror -Denable_kmods=True -Dlibdir=lib –default-library=static x86_64-native-linuxapp-gcc ninja -C x86_64-native-linuxapp-gcc -j 50

meson configure -Dexamples=skeleton x86_64-native-linuxapp-gcc ninja -C x86_64-native-linuxapp-gcc

265.2. Running the Application

To run the example in a linux environment:

./build/examples/dpdk-skeleton -c 2 -n 4

Refer to DPDK Getting Started Guide for general information on running applications and the Environment Abstraction Layer (EAL) options.

265.3. Test case: skeleton

Running:

./x86_64-native-linuxapp-gcc/examples/dpdk-skeleton  /build/basicfwd -c 2 -n 4

waked up:

Core X forwarding packets.

Send one packet from port0, check the received packet on port1. It should receive the packet sent from port0.
