Hello there,

Thanks for your KB thread.

Please check the manual for SNMP Traffic Sensor. It explains what the channel means for Traffic In and Out.


The traffic that goes through the interface does not necessarily give you an overview of your WAN speed. The below article could be helpful in explaining how to perform tests for your WAN network.


With kind regards,
