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?

Don't you usually set Ignore Interface Discards on switches?
