Abstract: The precision time protocol (PTP) runs on the peer switches in an MLAG domain. PTP messages received by one peer switch on an MLAG interface is selectively peer-forwarded to the other peer switch on the same MLAG interface in order to coordinate a synchronization session with a PTP node. The peer-forwarded messages inform one peer switch to be an active peer and the other peer switch to be an inactive peer so that timestamped messages during the synchronization session are exchanged only between the PTP node the active peer, and hence take the same data path.

Abstract: Particular embodiments described herein provide for a system, an apparatus, and a method to manage precision time protocol (PTP) domains with different domain numbers. The system, apparatus, and method can include activities for receiving an incoming PTP message at a logical PTP interface, which corresponds to one or more PTP ports of the network element; the incoming PTP message includes a first domain number. The activities also include translating the first domain number of the incoming PTP message into a second domain number to be included in a field of an outgoing PTP message, the translating includes identifying an active domain number entry in an active domain numbers database that includes the second domain number and that is part of a configuration, which allows domain number translations for a PTP region that is defined by its PTP domain and that corresponds to the logical PTP interface.
