Windows Server 2016设置网卡的顺序

 

参考文章:
Grid Infrastructure on Windows: How to Set Bind Order of Network Adapters on Windows 2016 [2290811.1]
https://docs.microsoft.com/en-us/windows-server/networking/technologies/network-subsystem/net-sub-interface-metric

背景:在Windows下安装过rac的工程师都知道需要为public网卡和private网卡设置顺序:
在Windows Server 2016之前的版本中,可以通过如下的方式实现"public网卡在上面,private网卡在下面"

 

 

 

 

从Windows Server 开始,如上方式已经行不通了,也就是Windows Server 2016中根本没有设置网卡顺序的Tab页(即:如上的Tab页已经没有了) ,见下图:



从Windows Server 2016开始,需要通过设置每个网卡的InterfaceMetric来间接的"设置"网卡顺序.这一点,可以从如下网址中得到证实:
https://docs.microsoft.com/en-us/windows-server/networking/technologies/network-subsystem/net-sub-interface-metric

 

 

查看InterfaceMetric的命令,注意,如下的命令是在powershell中执行的:

设置InterfaceMetric的命令:

值得注意的是, InterfaceMetric的值是小值优先还是大值优先,目前我还没有从微软的官方文档上看到,也没有找到可以证实的方法.

另外:
关于InterfaceMetric的解释如下:

 

 

https://technet.microsoft.com/zh-cn/library/hh826135.aspx

 

 

InterfaceMetric
Specifies an array of metrics of IP interfaces.
When routes are chosen, the overall metric used to determine the preference is the sum of the route metric and the interface metric. 
Typically, the interface metric gives preference to a particular interface, such as using wired if both wired and wireless are available. 
The default value is automatic.
