I am attempting to monitor snmp traffic across a VLAN Sub-Interface (VLAN ID 240) on a Sonicwall NSA 2400 using snmp traffic sensor with PRTG Network Monitor 188.8.131.523.
The probe I am attempting to monitor from is also in VLAN 240 and I have conenctivity to the interface. I can add the VLAN Sub-Interface to PRTG with no problems, the interface appears and I can select it as normal. The sensor turns green but no data is ever recorded.
Would anyone be able to help?
