Just a question.
Whatever possessed you to change the baud rate on the X870 console port to 115200?
Every one of the other 2000+ network devices I look after, including all our other Extreme switches use 9600. Which means, each time I connect to our X870s I have to change the baud rate on Putty and remember to flick a really REALLY tiny DIP switch on my Bluetooth serial adapter.
The life of a network engineer is tough enough without these pointless hassles.
