> Where did you find this? 

Found out the hard way after buying and installing 20 of them. When a single node in a VC reboots, it starts switching traffic some seconds before it does STP so any loops that were previously blocked now flood - usually overloading the other 3400s on the network. Apparently this is just how the Broadcom chip works and cannot be fixed. That, twinned with some other significant stability issues, caused them to all go back for a refund. They did say a PR would be raised for this though I don't believe it has been - I can't find an external one, anyway.

The QFX51XX issue is currently a won't fix. Worked fine in 17.x, broke in 18.x. No documentation or reasoning for the change, other than giving the distinct impression that we don't spend enough for them to care.
