    Where should I set jumbo frames in a VMC environment?
    I set it up as in the picture, but it didn't work properly. What's wrong?

    How did you determine that it didn't work? And what is the use case you have in mind that requires Jumbo frames?
    As you correctly drew, jumbo frame support (generally speaking packets >1500 Bytes) needs to be enabled on all network devices in the path.

    Depending on your use case, you might have to also explicitly enable Jumbo Frame Support on your VMC: https://www.arubanetworks.com/techdocs/ArubaOS_87_Web_Help/Content/install-guide/virt-appl/appendix/jum-fra.htm

    Hi. Oliver.

    The User Guide has recommendations for Jumbo Frames. So I try to test applying it.

    However, when jumbo frames were activated as shown in the picture, communication between the controller and the AP did not seem to work.

    Also, the controller appeared and disappeared repeatedly in the conductor.

    Thanks.

    You need to enable Jumbo (MTU) on the vSwitch itself as well. I didn't see an arrow there in your diagram.
