Ok, after googling I found a very recent conversation on the same subject. But it seems there is divided discussion on interface discards.
And I apologize to Evan - I didn't understand his suggestion about turning off interface discards - I thought it was something configured on the device similar to the "fault-finding" items on HP switches but I found it in IM and I checked and indeed that switch doesn't "bubble" anymore. What's interesting about all the threads I read and my own experience is that many times I see interfaces reporting thousands of discards and no matter how hard we look the hardware never agrees with what IM is saying - aside from the fact that the hardware is sending SNMP info saying there is a problem. Whatever, Dartware typically blames the vendor for having a faulty implementation of SNMP and if we are going to accept that then in that case I think there is a reason enough to allow a global option for Set Behavior to ignore interface disregards and not have to set it switch by switch. Perhaps it shouldn't be set by default but at least give the admin the choice. If he sets it he gets what he pays for. Usually Dartware is pretty forward thinking and listens to the admins out there and I think this time the majority of admins would like to have the choice. regards, Kevin -----Original Message----- From: Kevin Wigle [mailto:[email protected]] Sent: 08 September, 2011 12:04 AM To: 'InterMapper Discussion' Subject: RE: [IM-Talk] SNMP Issues nope - in all the years in this job I have only seen 2 switches configured with that and they were local. If I set that option will that stop IM from bubbling? I still wonder, what does IM see that the hardware won't show me directly? And since IM is polling the hardware to get info to display bubbles - what is actually happening - and what is to be believed?
