Newbie Powershell - Network capture

Hello, at this point I need to accomplish a basic task in Powershell:

Since I have multiple network adapters configured, I need to pick the desired network adapter I want to capture packets from/to.

THen to get started, I write the Powershell script which will display the respective packet output.

Can you someone point me a to a script which can let me do that or kindly give me an example?

Thanks,

M
