If the status or quality of clock sources on a clock synchronization network does not remain stable, configure the automatic clock source selection mode to ensure that the NetEngine 8000 F selects an optimal clock source.
The NetEngine 8000 F supports three clock source selection modes: automatic clock source selection, manual clock source selection, and forcible clock source selection. In automatic clock source selection mode, the NetEngine 8000 F uses the automatic clock source selection algorithm to determine a clock source to be traced. The reference factors for automatic clock source selection include priorities, synchronous status message (SSM) levels, and clock IDs of clock sources. The automatic clock source selection algorithm uses one or more of the reference factors, depending on the actual configurations.
