In one embodiment, methods for monitoring devices within a network by a controller are described. The method may include receiving a first request from a first device to authenticate a role of the first device as a grandmaster in a precision time protocol (PTP). Additionally, the method may include granting the first request designating the role of the first device as the grandmaster. The method may further include receiving a second request from a second device to authenticate that a clock announce message is from an authorized grandmaster. Additionally, the method may include determining whether the first device is authorized to send the clock announce message to the second device and, based on the determining, sending a message granting or denying permission for the first device to sync with the second device.
