Problem with Interface.xml retrieving IfInOctets data

[Mombo]

I am running Cacti 8.4 and I would like to retrieve the InInOctets and IfOutOctets from the router using SNMP.

I used snmpwalk to verify the OID and it does retrieve the required data. Wehn inserting the OID in the XML script and checking from the verbose query retrieved by polling a host, the above two OID are always skipped.

Please advise.
