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
2.7.2 Configuring the Clock Source Protection
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.
