source-interface interface-type interface-number : Specifies the source interface for NTP messages.
In an NTP message the local device sends to the NTP server, the source IP address is the primary IP
address of this interface. interface-type interface-number represents the interface type and number.
version number : Specifies the NTP version, where number is in the range of 1 to 3 and defaults to 3.
Description
Use the ntp-service unicast-server command to designate an NTP server for the device.
Use the undo ntp-service unicast-server command to remove an NTP server designated for the
device.
No NTP server is designated for the device by default.
z
To synchronize the switch to another device in a VPN, you need to provide vpn-instance
vpn-instance-name in your command.
z
If you include vpn-instance vpn-instance-name in the undo ntp-service unicast-server
command, the command will remove the NTP server with the IP address of ip-address in the
specified VPN; if you do not include vpn-instance vpn-instance-name in this command, the
command will remove the NTP server with the IP address of ip-address in the public network.
