Then DFM will be polling these devices.  How are you testing the fault conditions?  That is, for one device which should be showing an alert in DFM, what is wrong with it EXACTLY?  If you have brought an interface down on the device, make sure that interface is down long enough for DFM to see it down.  For example, the default polling interval in DFM is four minutes.  If you bring down a managed interface, make sure it is down for at least four minutes for DFM to detect the fault.


If you're sure that DFM should be seeing these faults and it is not, start a sniffer trace filtering on udp/161 and ICMP traffic to this one device.  Let that trace run for at least eight minutes, then stop it.  If you post the trace, I can look at it to see if there are any obvious problems.  Additionally, post the output of the pdshow command.

Exactly which version of DFM are you using?

In what state are the devices in DFM? That is, are they Known, or are they in a Learning or Questioned state?
