DGS-3630 Layer 3 Stackable Managed Switch CLI Reference Guide Example This example shows how to display SNTP information. Switch#show sntp SNTP Status SNTP Poll Interval : Enabled : 720 sec SNTP Server Status: SNTP Server Version Last Receive 10.0.0.11 4 00:02:02 10::2 FE80::1111vlan1 Total Entries:3 Switch# 36-6 sntp server (Hybrid Mode Only) This command is used to allow the system clock to be synchronized with an SNTP time server. Use the no form of this command to remove a server from the list of SNTP servers. sntp server {IP-ADDRESS | IPV6-ADDRESS} no sntp server {IP-ADDRESS | IPV6-ADDRESS} Parameters IP-ADDRESS IPV6-ADDRESS Specifies the IP address of the time server which provides the clock synchronization. Specifies the IPv6 address of the time server. Default None. Command Mode Global Configuration Mode. Command Default Level Level: 12. Usage Guideline SNTP is a compact, client-only version of the NTP. Unlike 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 within 100 milliseconds of the accurate time, but it does not provide the complex filtering and statistical mechanisms of NTP. In addition, SNTP does not authenticate traffic, although you can configure extended access lists to provide some protection. Enter this command once for each NTP server. Create multiple SNTP servers by enter this command multiple times with different SNTP server IP addresses. 344
