Pause parameters for ens192:
Cannot get device pause settings: Operation not supported

-a 查看网卡中 接收模块RX、发送模块TX和Autonegotiate模块的状态：启动on 或 停用off。
-A 修改网卡中 接收模块RX、发送模块TX和Autonegotiate模块的状态：启动on 或 停用off。
-c display the Coalesce information of the specified ethernet card。
-C Change the Coalesce setting of the specified ethernet card。
-g Display the rx/tx ring parameter information of the specified ethernet card。
-G change the rx/tx ring setting of the specified ethernet card。
-i 显示网卡驱动的信息，如驱动的名称、版本等。
-d 显示register dump信息, 部分网卡驱动不支持该选项。
-e 显示EEPROM dump信息，部分网卡驱动不支持该选项。
-E 修改网卡EEPROM byte。
-k 显示网卡Offload参数的状态：on 或 off，包括rx-checksumming、tx-checksumming等。
-K 修改网卡Offload参数的状态。
-p 用于区别不同ethX对应网卡的物理位置，常用的方法是使网卡port上的led不断的闪；N指示了网卡闪的持续时间，以秒为单位。
-r 如果auto-negotiation模块的状态为on，则restarts auto-negotiation。
-S 显示NIC- and driver-specific 的统计参数，如网卡接收/发送的字节数、接收/发送的广播包个数等。
-t 让网卡执行自我检测，有两种模式：offline or online。
-s 修改网卡的部分配置，包括网卡速度、单工/全双工模式、mac地址等。

bring up 的英文解释

bring up作为计算机专业术语的解释如下：cause to load(an operating system) and start the initial processes。
因此它的意思是“使......启动、调试、唤醒、让......跑起来”。

注意一下如果你想使用nutui来生成网卡配置文件，需要启动NetworkManager,生成之后建议马上关闭，否则你在重启网络的时候可能会死机．
因为nutui需要NetworkManager的支持.

Mar 23 10:40:20 k3master systemd[1]: Started LSB: Bring up/down networking.
复制代码

最后关闭NetworkManager开机启动

[root@k2master network-scripts]# systemctl disable NetworkManager
Removed symlink /etc/systemd/system/multi-user.target.wants/NetworkManager.service.
Removed symlink /etc/systemd/system/dbus-org.freedesktop.NetworkManager.service.
Removed symlink /etc/systemd/system/dbus-org.freedesktop.nm-dispatcher.service.

小结错误信息会包括

１，网卡配置文件不存在
　　存在多余网卡信息，需要先删除
２，Failed to start LSB: Bring up/down networking
３，network[65478]: RTNETLINK answers: File exists
４，Could not load file '/etc/sysconfig/network-scripts/ifcfg-lo'
操作不当可能造成死机，所以要注意
