I have a problem with SNMP traffic sensors on some server interfaces. I create the sensors manualy. When I get the list of interfaces, they are all there and I select the ones I am interested in. But as soon as PRTG starts polling them, it fails, giving "No Such Name (SNMP error #2)".
I suspect this happens when the ifAlias and/or ifDescription has a colon character (:) in it. For example, I am looking at an interface that has ifDescription "Device vmnic0 at 03:00.0 bnx2", and ifAlias "03:00.0".
How can I work around this?
