PTF 安装及简单测试 Packet Testing Framework

PTF

Longer Start

需要先安装的东西：

    Python 2.7

    Scapy

    pypcap (optional - VLAN tests will fail without this)

    tcpdump (optional - Scapy will complain if it's missing)

Install PTF

git clone [email protected]:Wasdns/ptf.git

如何写ptf程序？

    run_client.sh: a wrapper around ptf

    switch_sai_thrift: empty directory, this is where the Python bindings to program the switch's control plane would be copied

    mytests/sai_base_test.py: a wrapper Python class around PTF's BaseTest class. It is the base class for all the tests we added to mytests/switch.py

    mytests/switch.py: some example tests

在安装p4factory的前提下，跑个样例

cd $P4FACTORY/tools/

sudo ./veth_setup.sh

cd $P4FACTORY/targets/switch/

make bm-switchsai

sudo ./behavioral-model

cd <ptf-dir>/example/

sudo ../ptf --test-dir mytests/ \

     --pypath $P4FACTORY/targets/switch/tests/pd_thrift/

     --interface 0@veth1 --interface 1@veth3 --interface 2@veth5 \

     --interface 3@veth7 --interface 4@veth9 --interface 5@veth11 \

     --interface 6@veth13 --interface 7@veth15 --interface 8@veth17
