Hi there,

I think you will have to use both the SNMP Traffic Sensor and the SNMP Rmon Sensor to get all the metrics you want. The problem is, that the "transmitted" channel does not provide the actual traffic, as explained here.
If you don't need only CRC errors, but all errors from an interface, you can also use the SNMP Traffic Sensor with the "additional channel" "Errors in and Errors out" activated.

Kind regards,
