How to configure the system clock for Huawei MA5600 series

Here we describes how to configure the system clock to restrict the clock frequency and phase of each node on a network within the preset tolerance scope. This prevents transmission performance deterioration caused by poor timing at both the transmit and receive ends in the digital transmission system. This configuration also works for Huawei MA5603T and Huawei MA5608T.

Background Information

On a digital network comprising the MA5600 series and other devices, the primary problem is clock synchronization. To ensure that the system uses a unified clock standard, you must specify the clock signals from a certain port as the system clock source.

Procedure

1.           Run the clock source command to configure the system clock source.

Specify the clock signals extracted from a certain port as the system clock source.

2.           Run the clock priority command to configure the priority of the clock source.

Example

To obtain two clock sources from ports 0/5/0 and 0/5/1 of the SHEB board as clock source 0 and clock source 2 of the system, configure clock source 2 with the highest priority, and configure clock source 0 with the second highest priority, do as follows:

huawei(config)#clock source 0 0/5/0

huawei(config)#clock source 2 0/5/1

huawei(config)#clock priority sdh 2/0
