I've been researching this for about 2 hours now and and I have the basic cmd:
wmic path Win32_PerfRawData_Tcpip_NetworkInterface Get BytesReceivedPersec,BytesSentPersec,BytesTotalPersec
I don't want the bytes for all of my network interfaces.

I want to get the total bytes for a certain interface, does anybody know how to do this because I cannot find anything on here or the web.
