You can use the Get-NetAdapter cmdlet to display all network adapters on the server that have a link speed of 100 megabits per second (Mbps) like this:
PS C:\> Get-NetAdapter | Where-Object -FilterScript {$_.LinkSpeed -eq “100 Mbps”}
Name InterfaceDescription ifIndex Status MacAddress LinkSpeed
———– —————————— ——- —— ——————– ———
Ethernet 2 Broadcom NetXtreme Gig… 13 Up A4-BA-DB-0A-96-0C 100 Mbps
Ethernet Broadcom NetXtreme Gig… 12 Up A4-BA-DB-0A-96-0B 100 Mbps
The output of this command consists of objects that can be passed through the pipeline to other cmdlets. For example, you could pipe the output into the Set-NetIPInterface cmdlet to assign a metric value of 5 to all interfaces having a link speed of 100 Mbps as follows:
PS C:\> Get-NetAdapter | Where-Object -FilterScript {$_.LinkSpeed -eq “100 Mbps”} | `
Set-NetIPInterface -InterfaceMetric 5
