Abstract
Systems, methods, and devices are described which implement an internal Precision Time Protocol (PTP) instance on a stacked network device within a larger external PTP instance in the network to which the stacked network device. The internal instance of PTP is local to the stacked network device synchronizes the N devices ('members') in the stack. Each of the members of the stacked network device may act as a BC in this local virtual instance of PTP. One member, which may be referred to as the commander node or primary member node, may synchronize its clock based on an external GSC or external BC, and then that member may act as a BC for a downstream member, and so on in an iterative manner until all of the members within the stacked network device have synchronized clocks. The individual members may also act as BCs to the external endpoints coupled thereto, providing PTP timestamp messages to those endpoints.
