The maximum number of provisionable servers on the network processor is five. The NTP client automatically queries servers and synchronizes to the best clock by considering the stratum value of the servers and the dispersion (latency). The maximum number of network processors that can be provisioned as the timing sources on a shelf processor is two. If more than one external timing server is provisioned, the system reverts to the backup network processor in the event the primary server is not reachable or servicing time of day requests.

For procedures on provisioning time of day synchronization parameters using Site Manager, see Security and Administration, 323-1059-302.
