Syncing the master key when creating a device group

When you attempt to create a Device Service Clustering (DSC) device group, the device that you are logged in to sends a copy of its BIG-IP configuration, including the master key, to all other devices that join the device group. In a working device group, the same master key lives on all devices.
For example, suppose you have two devices,
Device_A
and
Device_B
, and you want to create a device group. You can log in to
Device_A
, navigate to the Device Trust settings, and specify that you want
Device_B
to be the device that joins
Device_A
to comprise the trust domain. Then, while still logged in to
Device_A
, you can create a device group with both devices as members.
In this case, when
Device_B
joins the device group, it receives a copy of
Device_A
's master key, as part of the initial config sync that the BIG-IP system does to form the device group.
