  • VPP环境搭建及配置

    git下载源码:https://github.com/vpp-dev/dpdk

    • VPP编译:

    1.cd vpp; compiler /bin/bash
    2.cd vpp; make install-dep 下载依赖包
    3.cd vpp/build-root; make distclean; ./boostrap.sh
    4.cd vpp;make; make build(debug版);make build-release(release版);

    • 配置文件:startup.config

    /*****************************************************************************/
    unix {
      Interactive //将CLI命令加入到输入输出,提供调试
      log /tmp/vpp.log //日志
      full-coredump //请求Linux内核转储所有内存映射地址区域
      cli-listen 127.0.0.1:5002 //绑定CLI监听TCP端口5002
    }

    api-trace {
      on //程序崩溃时可以追踪
    }

    cpu {
      //works <n> //创建n个线程
      //skip_cores <n> //对于worker线程来说跳过前n个核
      main-core 0 //将主线程分配给第0个核
      corelist-workers 1-3 //将worker线程放到核1 2 3上
    }

    dpdk {
        dev default {
               num-rx-desc 4096
               num-tx-desc 4096
             }
      dev 0000:04:00.0 {num-rx-queues 1} //将网卡与网卡驱动绑定
      dev 0000:04:00.1 {num-rx-queues 1}
      dev 0000:05:00.0
      dev 0000:05:00.1
      num-mbufs 128000 //IO缓冲区数量
      socket-mem 2048 //vpp感知NUMA,在NUMA0上分配2G内存
    }

    plugins{
        path /sf/data/vpp-multi/vpp-rxq/build-root/install-vpp-native/vpp/lib64/vpp_plugins
        //插件路径
    }
    /*****************************************************************************/

    • 运行脚本:run.sh

    #!/bin/bash
    export LD_LIBRARY_PATH=/sf/data/vpp-1710/vpp/build-root/install-vpp-native/vpp/lib64
    /sf/data/vpp-1710/vpp/build-root/install-vpp-native/vpp/bin/vpp 
    -c /sf/data/vpp-1710/vpp/startup.conf

    • dpkd绑定网卡相关操作

    查看dpdk绑定的网卡
    cd /sf/dpdk/sbin
    dpdk绑定网卡:
    ./dpdk-devbind --bind=igb_uio 0000:01:00.0
    dpdk解绑网卡:
    ./dpdk-devbind -u 0000:01:00.0
    将dpdk管理的网卡换成内核管理
    echo “0000:01:00.0” >/sys/bus/pci/driver/igb_uio/unbind
    echo “8086 100e” >/sys/bus/pci/drivers/网卡类型/new_id

    • vpp命令行:

    show int 查看基本信息
    show hardware-interfaces 查看收发队列的个数
    show interface rx-placement 查看收发队列分配
    show run 查看vpp运行信息
    show threads 查看线程信息
    开启二层转发:
    set interface state TenGigabitEthernet4/0/0 up 
    set interface state TenGigabitEthernet4/0/1 up
    set interface l2 bridge TenGigabitEthernet4/0/0 200
    set interface l2 bridge TenGigabitEthernet4/0/1 200
