Yesterday was interesting! We have a stack of 2x 5520s in one area of our school and someone put a patch cable from a port on one switch to a port on the other. This brought down the entire school
We have 2x Cisco Catalyst 4507 core routers with various Nortel & Cisco switches and most of them were affected at some point. They would go down then come up randomly.
I had a look at the Catalyst that the 5520s in question was connected to and saw a broadcast storm coming from it so I disconnected it and all settled. Then I found this loop cable on the 5520s.
The question is how do I stop this from happening again? I believe this has happened before my time here and a Nortel tech came to make a change that would keep any loop like this inside the switch and not affect any other switches but it appears this was not done on this switch.
Any ideas?
