Network Synchronization Support
Most services that are provided over networks must be fully synchronized in order to operate correctly.
If the network devices that constitute a network do not operate at the same clock rates, there is an overall
decrease in the performance of the network and a consequent degradation in the quality of the services
offered by the network. This document explains how to configure network synchronization on Cisco
ASR 1000 Series Aggregation Services Routers.
