III. Configuration procedure
Configurations on the Switch A (configure the master clock).
# Set the interface POS 1/1/1 to work in master clock mode, using local clock signals.
<Sysname> system-view
[Sysname] interface pos 1/1/1
[Sysname-Pos1/1/1] clock master
Configurations on the Switch B (configure the slave clock).
# Set the line clock source input interface on Switch B to POS 1/1/1.
<Sysname> system-view
[Sysname] clock lpuport pos 1/1/1
# Set the interface POS 1/1/1 to work in slave clock mode.
[Sysname] interface pos 1/1/1
[Sysname-Pos1/1/1] clock slave
# Enable the clock source from POS 1/1/1; set the clock to work in manual mode and
adopt clock source 8, which corresponds to slot 1 (refer to
[Sysname] clock manual source 8
Through the above configurations, all the other POS interface cards get the same clock
frequency derived by the clock monitoring module from the port 1 line clock of the POS
interface card in slot 1. In this way, all the service cards on the device can get precise,
reliable, synchronized SDH line interface clock signals.
