I’ve noticed that your email goes out twice. Also, without trying to peruse your configs (respectfully, I’m not JTAC), are you having a problem? Is something not working?
Me0 is not mandatory to manage the switch, but it is advised as an OOBM (Out Of Band Management) channel for management purposes. As far as your Jumbo Frames, you might want to check the MTU settings on the connecting devices to these switches as well.

I'm assuming mtu should be higher to allow some overhead on the packet. I have noticed that there are quite a few gaint frames in the network. Also do I need to use the me0 interface for management of the switch for access ? For a better view I've attached the configs of both switches.
