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.
Background Information
On a digital network comprising the MA5600 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
- 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.
- 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
