Hello all
I'm currently very confused about the Jumbo MTU configuration on Nexus 9336C and 31108TCV running NX-OS 9.3(7).
As with the old Nexus 5548, I've configured a network qos policy. On the interfaces with servers attached to, I see the Jumbo Frames counter increasing, while the Giants and input error counter remains at 0. But the servers don't work with jumbo frames on the new Nexus and work again once plugged into the old switch.
About the confusion, this document here states that if the Jumbo counter increases while the Giants doesn't increase, it should be correctly forwarded:

While this document here states, that I probably should configure it on a per interface basis:
https://www.cisco.com/c/en/us/support/docs/switches/nexus-9000-series-switches/118994-config-nexus-00.html
So which one is correct? For time reasons I can't currently further test this until the new maintenance window.
