    What is the difference between RAP MTU and SAP MTU?


    Is RAP for Remote Access Point and SAP for CAP?

    Check this part of the documentation:

    SAP MTU

    MTU, in bytes, on the wired link for the AP. The supported range is 1024-1578 bytes.

    RAP MTU

    Configures the maximum size of the GRE packets exchanged between a RAP and the controller. The supported range is 1024-1578 bytes and the default value is 1200 bytes.

    So SAP MTU is for the wired port, the RAP MTU for the GRE tunnel MTU.
