Multiple PreShared Key (MPSK) is the ideal replace for the old-fashioned static PSK environments. MPSK provides the flexibility and scalability which traditional PSK networks are lacking. MPSK provides a per device pre shared key. Aruba ClearPass is the authentication server to verify the pre shared key entered on a device. To create a pre shared key, you have to register a device in the Guest Device Repository in ClearPass.
During the registration and afterwards when editing the device, you don’t have the option to manually generate a MPSK. However there is an option to manually set the MPSK by importing a device and setting the MPSK in the Excel / CSV file. You can achieve this by adding to extra columns to the CSV file, called mpsk and mpsk_enable.
mpsk_enable should have a fixed value of 1 and mpsk is the actual key you like to use for the device.
This way you still have the flexibility to add / import multiple devices at once and generate the MPSK manually per device of use the same MPSK for multiple devices, like Sonos or Ring endpoints.
