configure ntp local-clock stratum

configure ntp local-clock stratum stratum_number


Configures the internal local clock with a stratum number. The stratum number defines the distance from the reference clock. The lower the number, the closer the switch is to the reference clock.

Syntax Description

stratum_number Specifies the distance from the reference clock from 2 through 16, with 2 being closest and 16 being the farthest away.


The local clock is disabled by default.

Usage Guidelines

The internal local clock is configured as a clock source with a given stratum number. Because the local clock is not as reliable as an external clock source with GPS or CDMA, the stratum number should be higher than the stratum number of the external clock source to allow the system to acquire the most reliable clock information from the clock source lists.


The following command configures the local clock with a stratum number of 3:

configure ntp local-clock stratum 3
