You can achieve this by creating a Net QOS Policy via PowerShell. This cannot be done in the GUI.
To create a policy open PowerShell as administrator and run:
New-NetQosPolicy “Replication Traffic from vmms.exe" -IPPortMatchCondition 80 -AppPathNameMatchCondition *vmms.exe -IPProtocolMatchCondition TCP –ThrottleRateActionBitsPerSecond 500000000
The ‘ThrottleRateActionBitsPerSecond’ parameter is the speed in bits oer second. 500000000 is 500Mbps.
