Claim:
1. One or more non-transitory computer-readable media having embodied thereon computer-usable instructions that, when executed by a processing device, perform a method of characterizing a synchronization behavior of a slave device by dropping sync packets, the method comprising: transmitting a sequence of sync packets from a grandmaster device to the slave device, wherein the slave device includes a clock source, and wherein the sequence of sync packets is usable by the slave device to synchronize the slave device with the grandmaster device; modifying the transmitted sequence of sync packets such that one or more sync packets are removed from the sequence, providing a pattern of removed sync packets; while modifying the transmitted sequence of sync packets, storing a characterization of the synchronization behavior of the slave device, wherein the characterization includes an indication of whether the slave device is synchronized or not synchronized with the grandmaster device while the sequence of sync packets is modified; wherein prior to said modifying the transmitted sequence of sync packets, determining that the slave device is synchronized with the grandmaster device.
