Clock monitoring module configuration example
Network requirements
• Device A and Device B are connected through the POS interfaces. Device A is equipped with clock
monitoring module on its SRPU.
• The synchronized clock of Device A is provided by the clock monitoring module on its SRPU.
• Device B adopts the line clock from Device A to synchronize with the SDH line of Device A.

Configuration procedure
1. Configure Device A (master clock):
# Set the interface POS 3/1/1 to work in master clock mode, using local clock signals.
system-view
[DeviceA] interface pos 3/1/1
[DeviceA-Pos3/1/1] clock master
2. Configure Device B (slave clock):
# Set the LPU port on Device B to POS 3/1/1.
system-view
[DeviceB] clock lpuport pos 3/1/1
# Set the interface POS 3/1/1 to work in slave clock mode.
[DeviceB] interface pos 3/1/1
[DeviceB-Pos3/1/1] clock slave
[DeviceB-Pos3/1/1] quit
