Explanation

The "ntp master" is used to configure the device as a master clock when external time synchronization is not possible; for example, the router is not connected to the Internet. If the network has ntp master configured and it cannot reach any clock with a lower stratum number, the system claims to be synchronized at the configured stratum number, and other systems synchronize to it via NTP. By default, the master clock function is disabled. When enabled, the default stratum is 8. In the world of NTP, stratum levels define the distance from the reference clock. A reference clock is a stratum-0 device that is assumed to be accurate and has little or no delay associated with it (typically an atomic clock). A server that is directly connected to a stratum-0 device is called a stratum-1 server, a server that is directly connected to a stratum-1 is called a stratum-2 server and so on. products_command_reference_chapter09186a008007dec6.html
