I'm evaluating PRTG, and I'm getting implausible values for interface speeds on our Nortel based network core devices (8600). Can you advise how to diagnose this ?

Thanks.

Thanks for your response: I'm using "SNMP Traffic" to monitor mainly 1Gb and a few 10Gb links.

If you scan against the same OID using our SNMP Tester, what results do you get?
