TRex

Trex是思科的一款基于DPDK的网络测试工具。首先安装centos 7.5，然后安装kernel-devel-3.10.0-862.el7.x86_64.rpm。

最好不要用# yum install kernel-devel，以免安装了最新的，和当前kernel不匹配。

下载MLNX_OFED_LINUX-4.4-1.0.0.0-rhel7.5-x86_64.iso，安装：

./mlnxofedinstall  --upstream-libs --dpdk --without-fw-update

下载DPDK，https://github.com/DPDK/dpdk.git

编译DPDK：

export RTE_SDK=`pwd`;
export RTE_TARGET=x86_64-native-linuxapp-gcc;
make install T=x86_64-native-linuxapp-gcc -j16

下载TRex：

wget https://trex-tgn.cisco.com/trex/release/latest -O /tmp/trex_latest
mkdir /usr/trex
tar -xvf /tmp/trex_latest -C /usr/trex

配置 /etc/trex_cfg.yaml

sudo ./t-rex-64 -c 4 -i

然后再另外一个窗口：

./trex-console
trex>start -f stl/udp_1pkt_tuple_gen.py -p 0 -m 1%
trex>stop

输出如下：
