New 2019 deployments!
What is the best practice regarding jumbo? A couple months ago I had a customer core switch fragmenting packets from a controller for years and CPU utilization was over 70% this entire time. (Illustrated with monitoring software) After jumbo deployed to the controller the CPU dropped to..30-40%.
Fundamentals guide states.
To achieve maximum performance benefits with Tunnel Mode, end-to-end jumbo frame support
should be enabled on a wired switch due to the increased aggregation introduced with the IEEE
802.11ac standard.
Do you deploy jumbo to APs or just the controller side? I'd assume Jumbo support from AP to controller.
What about when doing PUTN or PPTN with switches? Same situation I'd guess...?
