I am tuning the DFM to filter the alarms that I don't want to see. I am trying to setup "Expression Filering" in the DFM Console but I am not well versed in regular expressions. My problem is: I want to filter EVENT "Unresponsive" for CLASSES "Switch,RSM,Router" but I do not want to filter that event for CLASS "IP". The reason is the unresponsive event for Switch,Router,RSM will read as false if the SNMP agent does not respond but ICMP polls are successfull, this give a false alarm. The CLASS"IP" EVENT"Unresponsive" is only for ip connectivity which is what I want to see.
