Cisco 3850 Change MTU on just one port

[Ravs]

Hi Guys

We need to change the MTU to 9192 on just one port on the 3850 Switch. The rest of the 11 ports will still be at 1500.

Did some research and it's just stating System MTU which will change the MTU on all the ports.  We cant change the System MTU.

Secondly can we change the MTU on the 9500 to 9192 on just few physical ports and SVI. When we changed the System MTU the ospf adjacencies dropped.

Not possible.
MTU is global for 3850.

Hi,

    On most hardware switch platforms, the MTU is a system wide configuration, as the change is done at the ASIC's level (for this reason it also requires a reboot), not at the port level.
