DFM is missing environment traps

I am testing DFM before I install the software on site.

The problem is that DFM is not identifying environmental traps, have set the thresholds very low induced a high enough load on the router CPU and no results are being shown

Simple faults such as interfaces going down.


Re: DFM is missing environment traps

What specific env traps you're expecting DFM to alert for?. Temp/Power supply?

Re: DFM is missing environment traps

I'm expecting to see, alerts for high processor utilisation and memory alerts.

I have ensured the thresholds are low enough and pushed the 2610 above these thresholds, e.g 1% utilisation threshold for CPU!

I'm reciving traps for the up/down status of interfaces but this is all.

Any ideas?

Re: DFM is missing environment traps

I have seen similar results where nothing appears to be happening with traps, any fault conditions are detected via the periodic polling mechanism, not dynamically via trap handling.

Cisco have suggested altering the log window update frequency; Extract from message train of 'Ask the Expert Forum' follows :


Thanks for the reply.

Yes it's a good point about the message console display frequency as DFM may be detecting events but not displaying them, although I would expect an event to pop up as soon as it is processed.

Thanks for the URL, I had already seen the Apppendix in the user guide with the defined traps.

I will deal with any similar issues in the future on a case by case with the TAC.

Hi Ian,

You are correct - if you pulled out a network connection, DFM should

generate a notification for that since it acts upon the standard link

up/down traps. One possibility is that the refresh frequency of your

monitoring console is set to update at a lower frequency. In any case,

provided you have a CCO login, you can access the DFM user guide which

points you to which traps that the application listens for:

Hope this helps.
