Abstract
A method for making IEEE 1588 master clock configuration for an ONU in a PON includes creating a PTP port on a UNI of the ONU, and generating a corresponding PTP port ME for the PTP port to indicate that the UNI is operating in a master clock mode; generating a 1588 master clock configuration data ME based on PTP port MEs of all PTP ports in the ONU, to store profiles of all PTP ports used as master clock devices; and generating a clock data set ME according to the 1588 master clock configure data ME, to indicate clock source information of all PTP ports used as master clock devices.
