Example
To configure system clock resource 0 for receiving ACM clock packets from Layer 3 interface
whose IP address is 20.20.20.20 (assume that the subnet mask length is 24), run the following
commands:
huawei(config)#
vlan 14
huawei(config)#
interface vlanif 14
huawei(config-if-vlanif14)#
ip address 20.20.20.20 24
huawei(config-if-vlanif14)#
quit
huawei(config)#
port vlan 14 0/0 0
huawei(config)#
acm-clock-ip 20.20.20.20 0/2
huawei(config)#
clock source 0 acm-clock 0/2

3.8.1.2 Configuring the Line Clock Reference Source
The MA5616 supports tracing of the uplink GE, GPON line clock. The clock synchronized
through the physical layer and restored from the line code stream can serve as the reference
source of the system clock.
Procedure
Step 1
Run the
clock source srcindex frameid/slotid/portid
command to configure the clock restored
at a certain GE, GPON, or port as the reference source of the system clock.
Step 2
Run the
display clock source
command to check whether the line clock source information is
consistent with the data plan.
----End
Example
To configure clock source 0, set the reference source to the GPON line clock, and set the
reference source port to 0/0/1, do as follows:
huawei(config)#
clock source 0 0/0/1
Clock source set succeeded
huawei(config)#
clock priority system 0
Clock source priority set succeeded
huawei(config)#
display clock source

3.8.2 Configuring the Priority of the System Clock
This topic describes how to configure the priority for the clock reference source of the system.
The MA5616 selects the system clock according to the configured clock priorities.
