244 Managing General System SettingsThe switch can obtain the time from a Simple Network Time Protocol(SNTP) server, or you can set the time manually. Table 11-2 describes thesettings that help the switch keep track of time.Why Does System Information Need to Be Configured?Configuring system information is optional. However, it can be helpful inproviding administrative information about the switch. For example, if youmanage several standalone PowerConnect M6220, M6348, M8024, andM8024-k switches and have Telnet sessions open with several differentswitches, the system name can help you quickly identify the switch becausethe host name replaces console as the CLI command prompt.SDM Template Determines the maximum resources a switch or router can usefor various features. For more information, see "What Are SDMTemplates?" on page 248Table 11-2. Time SettingsFeature DescriptionSNTP Controls whether the switch obtains its system timefrom an SNTP server and whether communicationwith the SNTP server requires authentication andencryption. You can configure information for up toeight SNTP servers. The SNTP client on the switch canaccept updates from both IPv4 and IPv6 SNTP servers.Real time clock (RTC) If SNTP is disabled, you can manually enter the systemtime and date.Time Zone Allows you to specify the offset from CoordinatedUniversal Time (UTC), which is also known asGreenwich Mean Time (GMT).Summer Time In some regions, the time shifts by one hour in the falland spring. In the United States, this is called daylightsaving time.Table 11-1. System InformationFeature Description
