We have Ruckus APs (600 & 710s) connected to Brocade 7250 switches at one site with each building at the site having an IDF. For a lab in one building, there's an HP 2510-48 (for the lab computers) connected to the building Brocade 7250. Someone needed some special equipment (3-D printers I think) plugged into the network and there weren't enough ports in that corner of the room so they plugged in a wifi router to use as a dumb switch.
Either the wifi router or the special equipment took down several non-Brocade switches in other buildings and ALL the Ruckus 600s around the site (much like a broadcast storm). The 710s stayed up and none of the Brocade switches went down.
I thought I had the Brocades correctly set to disable the ports in the event of a broadcast storm but whatever this was got past the Brocades and affected the entire site. And I'm not sure but I think that the switches/APs didn't actually go down, there was just enough network congestion that our monitoring software couldn't ping them reliably.
Regardless, I'm hoping someone could give me some ideas of what to look for and maybe how to prevent it in the future.
Thanks in advance.
