When I tested bandwidth my network, I was monitoring two clients who made a load and a switch. Each clients showed about 950 Mb, but switch shows about 400 Mb. After changed the Scanning Interval from 60 seconds to 30 seconds, I can see a real bandwidth on switch.

This very much looks like an overflow issue. Please make sure that the parent device to this sensors is set to SNMP v2c, then add the sensors again. Do they (the new sensors) show proper results now with 60 seconds as scanning interval?

I removed a device, made a new device, set to SNMP v2c and a Scanning Interval to 60 seconds. And I see again an old result. If need I can make a screen shots.
