I'd like to know if this statement is true...
"A multicast storm occurs when STP fails (for whatever reason) to do it's job of blocking ports on redundant uplinks hence allowing loops to form. Therefore in the event of a multicast storm one quick way to stop it would be to manually remove one of the two uplinks from each edge switch stack to the core switch stack in effect manually breaking the loop."
This sounds right to me but I'd like some further opinions. Also, on a more general note, what else can one do if one experiences a multicast storm to isolate the source of the problem?
