Using CiscoWorks LMS and I notice the notification threshold for switch port utilisation is set at 40%. I know I've seen this before, but I can't remember why 40% was the magic number. I've Googled and come up with nothing useful so I'm handing it over to the experts :)
Does this have something to do with this value being an "average" rather than a peak? I'm struggling to understand why, in a fully switched network, 40% utilisation is something to be concerned about.
Hope you can improve my education :)
