DGS-6604 m sntp server sntp server Use this command to allow the system clock to be synchronized with the SNTP time server. To remove a server from the list of SNTP servers, use the no form of this command. sntp server IP-ADDRESS no sntp server [ IP-ADDRESS ] Syntax Description IP-ADDRESS IP address of the time server which provides the clock synchronization. Default Command Mode Usage Guideline Example Not configured Global configuration When using no sntp server without any option, the Switch will delete all configured SNTP servers and synchronization with the SNTP server will be disabled. SNTP is a compact, client-only version of the NTP. SNTP can only receive the time from NTP servers; it cannot be used to provide time services to other systems. SNTP typically provides time within100 milliseconds of a precise time source, but it does not provide the complex filtering and statistical mechanisms of NTP. In addition, SNTP does not authenticate traffic, although it can be configured with extended access lists to provide some protection. Enter this command once for each NTP server. The switch must be configured with this global configuration command in order to enable SNTP. Create multiple SNTP servers by entering this command multiple times with different SNTP server IP addresses. The time obtained from the SNTP server refers to the UTC time. The following example shows how to configure a switch to allow its software clock to be synchronized with the clock by the SNTP server at IP address 192.168.22.44: Switch# configure terminal Switch(config)# sntp server 192.168.22.44 Switch(config)# end Verify the settings by entering the show sntp server command.
