How can I know all the incoming and outgoing data traffic from a WR-Transport?

I need to know how many data is being sent and received through my transport, in order to compare the information with the one received by my carrier. Thank you.

From a command line you can read the stats using:
at\mibs=ppp.1.stats

You can clear these stats with:
at\mibclr=ppp.1.stats

You can also see it in the webUI of TransPort Management - Network Status > IP Statistics
