A sample commandline to start a pktgen instance would look something like the following, which you may need ‘sudo -E’ added to the front if not superuser. The -E option of sudo passes environment variables to sudo shell as the scripts need the RTE_SDK and RTE_TARGET variables:
启动 pktgen 实例的示例命令行如下所示，如果不是超级用户，您可能需要将“sudo -E”添加到前面。 sudo 的 -E 选项将环境变量传递给 sudo shell，因为脚本需要 RTE_SDK 和 RTE_TARGET 变量：
./app/pktgen -l 0-4 -n 3 -- -P -m "[1:3].0, [2:4].1
Pktgen, like other DPDK applications splits its commandline arguments into arguments for the DPDK Environmental Abstraction Layer (EAL) and arguments for the application itself. The two sets of arguments are separated using the standard convention of -- as shown above.
与其他 DPDK 应用程序一样，Pktgen 将其命令行参数分为 DPDK 环境抽象层 (EAL) 的参数和应用程序本身的参数。 两组参数使用标准约定 -- 分隔，如上所示。
These commandline arguments are explained in the EAL Commandline Options and Pktgen Commandline Options.
这些命令行参数在 EAL 命令行选项和 Pktgen 命令行选项中进行了解释。
The output when running pktgen will look something like the following:
运行 pktgen 时的输出将如下所示：
