2.7 Configuring Clocks

A clock is the basis for the normal operation of an NE. You need to configure the clocks for all
the NEs before configuring services. In addition, you need to configure the clock protection in
the case of a complicated network.

2.7.1 Configuring the NE Clock Source

Before configuring services, you must configure the NE clock source and specify the priority
level to ensure that correct clock trace relations are created for all the NEs on the network.
2.7.2 Configuring the Clock Source Protection
On a complicated clock network, you need to configure the clock protection for all the NEs.
After you set the clock source and specify the clock priority level for the NEs, you can enable
the standard SSM or extended SSM protocol to prevent the NEs from tracing an incorrect clock
source.
2.7.1 Configuring the NE Clock Source
Before configuring services, you must configure the NE clock source and specify the priority
level to ensure that correct clock trace relations are created for all the NEs on the network.
Prerequisite
You must be an NM user with "NE operator" authority or higher.
Background Information
To implement clock protection, you must configure at least two traceable clock sources for the
equipment. Generally, the tributary clock is not used as the clock source for the equipment.
After you set the clock sources for all the NEs, query the networkwide clock trace status again.
For details, see Querying the Clock Trace Status.

If the protocol controller is not started, select all the NEs of the protection subnet. Right-click and choose
Start/Stop Protocol > Start from the shortcut menu. Click Yes in the dialog box that is displayed twice.
Ensure that the status of all the values in the Protocol Controller column is Protocol Started.
The WTR time of all NEs in the same protection subnet should be the same.
