Configuring Input or Output Network Clocking
We recommend that you configure a stable input clock source from a GPS device before configuring PTP
master. The GPS device acts as a PTP grand master, and the BITS or 10-MHz port of a Cisco ASR
1002-X Router can be used to input or output the network clock. Perform these tasks to configure
network clocking on a Cisco ASR 1002-X Router:
