    Hello All, I have a good one..

    Suddenly, all my switches at my site on central (100+ 2930s/6300s) began reporting exceeding uplink usage within 5 minutes.. I think I may know the issue, but I want to see what everyone else thinks.

    From your other post, this may well be a network loop. Further analysis may make clear what device or where that loop is created.

    Hm, I've been investigating this. We experienced a cyber attack so I wasn't quite sure if that was why. The issue is still on-going. The only other change we've made is created a vlan and connected our other site that is on a different subnet. See below for my amazing artwork lol..
