Abstract: A network device may assign, to a port of a plurality of ports on the network device, a precision timing protocol (PTP) port priority for PTP communications between the network device and another network device. The network device and the other network device may be communicatively connected via a plurality of links in a link aggregation group (LAG). Each port, of the plurality of ports, may be associated with a respective link, of the plurality of links, in the LAG. The network device may generate a link layer discovery protocol (LLDP) frame that includes information identifying the PTP port priority assigned to the port. The network device may transmit the LLDP frame to the other network device to identify, to the other network device, the PTP port priority.

Abstract: A device may determine a link master/slave relationship for an Ethernet link associated with a connection between a component of the device and a component of another device. The device may determine that Synchronous Ethernet (SyncE) is to be enabled on the Ethernet link. The device may identify the component of the device as a SyncE slave or a SyncE master associated with enabling SyncE on the Ethernet link. The device may provide an indication that the component of the device has been identified as the SyncE slave or the SyncE master. The device may determine a SyncE master/slave relationship associated with enabling SyncE on the Ethernet link. The SyncE master/slave relationship may supersede the link master/slave relationship without altering the link master/slave relationship. The device may cause the component of the device to recover a clock based on the SyncE master/slave relationship rather than the link master/slave relationship.
