Switches are Unifi 48p POE.
We are having a broadcast storm that is pretty hard to troubleshoot. We are borrowing a layer2 link from our ISP that connects both our sites together via trunk, and our main site holds the gateway to the WAN.
Whenever a broadcast storm happens, it trips the ISPs switches so they disable us, so I can't go through and disconnect things until it starts working like I'd normally do.
So we have a link between two buildings, fiber, mm, connected with SFP+ modules.
When doing show interface counters I see Switch1 sending a moderate amount of broadcast traffic to Switch2 (moderate meaning nothing out of the ordinary), but when doing show interface counters on Switch2, I see a shitload of recieved broadcast traffic from Switch1, and of course a ton of broadcast traffic OUT of all the other ports on Switch2.
So Switch1 doesn't think it's sending that much broadcast traffic, but Switch2 is receiving a shitload of it from Switch1.
Could Switch1 be faulty? Or maybe one of the SFP+ modules causing frames to be re-transmitted?
This is my nightmare.
If you want exact numbers, Switch1 thinks it only sent 252627 packets to Switch2, but Switch2 says that it recieved 514,848,042. There is nothing inbetween switches, other than SFP+ modules and fiber in the ground.
And they were both rebooted about 3 hours ago.
