Ethernet Clock Syntonization Configuration - Huawei Quidway S9300 Configuration Manual

Quidway S9300 Terabit Routing Switch
Configuration Guide - Device Management
About This Chapter
The Ethernet clock syntonization technology synchronizes clocks through the Ethernet. This
chapter describes how to implement Ethernet clock syntonization on the S9300.
11.1 Overview of Ethernet Clock Syntonization
Compared with the Global Positioning System (GPS), the Ethernet Syntonization function
synchronizes the clock frequency on the Ethernet at lower costs.
11.2 Ethernet Clock Syntonization Features Supported by the S9300
This section describes the hardware of the S9300 required for implementing Ethernet clock
syntonization, and the clock sources and clock source selection modes supported by the
S9300.
11.3 Forcibly Specifying a Reference Clock Source
The S9300 allows you to forcibly specify a reference clock source flexibly.
11.4 Manually Specifying a Reference Clock Source
The S9300 allows you to manually specify a reference clock source flexibly.
11.5 Selecting a Clock Source Based on the Priority
When the SSM quality level is not used in clock source selection, you can select the clock source
based on the priority. This is a typical application scenario of Ethernet clock syntonization.
11.6 Selecting the Clock Source Based on the SSM Quality Level
If the SSM quality level is used in clock source selection, the S9300 selects the clock source
based on the SSM quality level and then based on the priority.
11.7 (Optional) Configuring Other Attributes of a Clock Source
This section describes the method of configuring other attributes of a clock source.
11.8 Configuration Examples
This section provides several configuration examples of Ethernet clock syntonization.
