trying to find some documentation on jumbo frame best practice.
I am currently investigating some issues on my network. 4500's at the core with MTU 9128 on all interfaces. Downstream I am using 3850's and 2960x's. These are not using Jumbo frames. I want to make sure I have a clear understanding of the impact, with documentation, before I suggest setting jumbo frames on all of these switches.
thanks

All the connected interface to be supported and agreed with Jumbo Frames.
here is some good explanation :

There is a good thread for reference :
