At this point, I think I just need to re-design this network and get some vlans in place and work from there. I should see a decrease in broadcast traffic if I do that. I'm going to split this building into 3 vlans so that all 3 floors are separate from one another. This should at least help me isolate the traffic and or this will calm the switch ports down.
