Which NTP command configures the local devices as an NTP reference clock source?
- NTP Peer
- NTP Broadcast
- NTP Master
- NTP Server
Explanation: From a Cisco perspective, getting the clock from an Internet time source and/or from a local timing device both require the same command (ntp server). To have a specific network device consider itself as a reference clock source, another command is used (ntp master)
For example, the command
Router(config)#ntp server 192.168.1.1
configures the local device to use a remote NTP clock source from 192.168.1.1 while the command:
Router(config)#ntp master 1
configures the local device as a NTP reference clock source with stratum of 1.
