windows通过命令获取mtu
代码语言：javascript复制一、支持＞2008R2的系统，不支持≤2008R2
#快
$NICName=(Get-WmiObject Win32_NetworkAdapter -Filter 'NetEnabled=True').NetConnectionID
Get-NetAdapter $NICName| Format-List *|findstr /i mtu
#快
$NICName=(Get-WmiObject Win32_NetworkAdapter -Filter 'NetEnabled=True').NetConnectionID
(Get-NetAdapter $NICName).MtuSize
#有点慢
$NICName=(Get-WmiObject Win32_NetworkAdapter -Filter 'NetEnabled=True').NetConnectionID
(Get-NetIPConfiguration -InterfaceAlias $NICName -Detailed).NetIPv4Interface.NlMTU
二、支持≥2008R2的系统
#快
$NICName=(Get-WmiObject Win32_NetworkAdapter -Filter 'NetEnabled=True').NetConnectionID
((netsh interface ipv4 show subinterface $NICName| Select-Object -Index 3).substring(0,14)).Trim(" `t`n`r")windows通过命令修改mtu：
