PowerConnect 3500 Monitor Errors on Interface

Good Day,

We use PRTG for monitoring, at the moment we  pull traffic in and out which works fine, we'd like to add errors but whenever we do it says "no such name" Whenever i queried PRTG Support they said

"

I'm very much afraid, we have seen this issue already a few times. The problem is then, that the target device simply does not have / offer values for those additional channels.

The OIDs for those are not available on the target device (http://www.paessler.com/knowledgebase/en/topic/26783-oids-of-traffic-sensor

s). There is nothing we can do to solve this though."

I'm trying to import a MIB to monitor (if possible) but there is a vast amount of MIB that is confusing me.

Any idea how to proceed?
