    The current firmware is running 8.4.0.0 on the controller.

    I try to configure summit netmask /22 but error message show 

    "Failed to add pool xxx which has more than 256 addresses".

    Does it support?

    Is it limitation of DHCP server on the controller?

    Check Table 22 in the ArubaOS 8.4.0.0 user guide for max leases and the command to increase to 512 for the smaller platforms. Max for smaller platforms is now 512.

    Can I do or more hidden command to increase more?
