An SNMP sensor setup against a Cisco router sub-interface returns no data, even though there is data traversing that interface. I believe this is because the sub-interface is configured as the dot1q native VLAN.
Does anyone know whether this is a bug/know problem with PRTG and whether it has been fixed in a more recent version?
Details: interface Ethernet0
interface Ethernet0.200000 description SNMP Sensor 1 - No Data encapsulation dot1Q 200 native
interface Ethernet0.200201 description SNMP Sensor 2 Shows Data Correctly encapsulation dot1Q 201
interface Ethernet0.200202 description SNMP Sensor 3 Shows Data Correctly encapsulation dot1Q 202
I am using PRTG version 188.8.131.521
