Volume 1-Configuration Fundamentals / Chapter 7-Time Configuration Configuration Commands In the following example, the user configures the clock on the Switch to be 14:45:00 on the 5th August 2010 and verifies that the time has been set correctly: DGS-6600:2>enable DGS-6600:15#clock set 14:45:00 5 August 2010 DGS-6600:15#show clock Current Time Source : No Time Source Current Time : 14:45:03, 2010-08-05 Time Zone : UTC +00:00 Daylight Saving Time : Disable Offset in Minutes : 60 From : N/A To : N/A DGS-6600:15# Automatic Configuration of Time The Switch supports the Simple Network Time Protocol (SNTP), which allows automatic time configuration on the Switch. SNTP is a client-only version of the Network Time Protocol (NTP). Unlike NTP, SNTP is a simplified protocol that does not support the packet authentication or other complex mechanisms. When an NTP server address is configured, the system will automatically synchronize the time with the NTP servers. Once the Switch has synchronized with a specific server, the Switch will re-synchronize with the specified server at regular intervals. Whenever the Switch synchronizes with the NTP server, the latest time will be reflected in the RTC. The SNTP server will always synchronize with the Switch using UTC time. After synchronizing with the SNTP server, the Switch's RTC will adjust to local time, according to the local time zone configured on the Switch. The following commands are used to configure SNTP: Command sntp server IP-ADDRESS show sntp clock timezone {+|-} HOURS-OFFSET [MINUTESOFFSET] show clock Explanation Configures the SNTP server.
