If the NTP server is on the publicnetwork, do not specify this option.ip-address: IP address of the NTP server. It must be a unicast address, rather than a broadcast address,a multicast address or the IP address of the local clock.server-name: Host name of the NTP server, a string of 1 to 20 characters.authentication-keyid keyid: Specifies the key ID to be used for sending NTP messages to the NTP server,where keyid is in the range of 1 to 4294967295.priority: Specifies this NTP server as the first choice under the same condition.source-interface interface-type interface-number: Specifies the source interface for NTP messages. In anNTP message the local device sends to the NTP server, the source IP address is the primary IP address ofthis interface. interface-type interface-number represents the interface type and number.version number: Specifies the NTP version. The value range for the number argument is 1 to 4, and thedefault is 3.
