DOCSIS Signal Levels reporting "nan"

Yes on all four counts.

As for the types of modems, we have a mix of Surfboard 4200/5100/5101 modems that we are monitoring, about 25 in total. Manually running the script server against the modems (I have tried modems from all three models) works just fine, and by that I mean I get valid data returned to me.

Any other suggestions here?

Hi,

For what it's worth - in our system I found that the Data Template DOCSIS Stats / 9:DownChannelPower was set to accept numbers between -80 and 80.

If the dBmV number in our management system for the CableModems shows -11.2 the OID .1.3.6.1.2.1.10.127.1 gives the number -112 which again was to low for the DataTemplate to handle.

Changing the negative number to -200 did the trick for me in our system.

But then again, I wouldn't have known where to even start searching without this chain of posts...

Thanks,
FrodeS
