NOTE
Packets from different base stations may carry different user VLANs. Ensure that user VLANs are consistent
with the actual ones during configuration.

14.4.3.7 Configuring Clock Synchronization
In this scenario, the synchronous Ethernet clock can be used to achieve network-wide clock
synchronization.
Prerequisites
l
The clock daughter board CKMC/CKMD of the SCU board must be in position.
l
The ethernet upstream board must be GICK/GSCA (GE port) or X2CS (10GE port)/SPUF
(need an independent service board slot).
l
The upstream MAN PSN of the OLT must feature the capability of Ethernet
synchronization.
Context
According to actual requirements, Ethernet base stations support synchronous Ethernet
(frequency synchronization) and 1588v2 (time synchronization). This document uses
synchronous Ethernet as an example. For details about how to configure 1588v2 time
synchronization, see "

Data
GIU upstream board Port: 0/19/0
ETH port on the
ONU
0/3/1
Procedure
l
Configure a clock on the OLT.
1.
Add a system clock source.
Configure the Ethernet line clock input from GIU port 0/19/0 as the system clock 0.
Set the priority to 0 (highest priority).
huawei(config)#
clock source 0 0/19/0
huawei(config)#
clock priority system 0
2.
Query configurations and the status of the system clock source.
Run the
display clock source system
command to query configurations and the status
of the clock source. Ensure that configurations of the system clock source are correct
and the status is
Normal
.
