It depends on what you are after. A broadcast storm will normally kill a CPU and so it does not matter what VLAN you were in as they would all suffer as the switch as a whole suffers
So monitoring something like CPU and MEM with a quick trigger is important in my mind as well as syslog.
And in actuality with a spanning-tree loop or a broadcast storm outside of CPU it is very hard to detect anything is wrong unless you have a high end switch and have black-plane monitoring or storm control in place.
Thanks, thats kind of what I suspected since the CPU sent from around 10% to 100% in seconds. I am looking at ways to control it on the switch but would like to get some sort of trap something is wrong.
