Section I: Basic Operations 47
Daylight Savings Time (DST)
Enables or disables the system’s adjustment for daylight savings time.
The default is enabled.
Note
The switch does not set DST automatically. If the switch is in a
locale that uses DST, you must remember to enable this in April
when DST begins and disable it in October when DST ends. If the
switch is in a locale that does not use DST, this option should be set
to disabled all the time.
Status
Enables or disables the SNTP client on the switch. The default is
disabled.
Server IP Address
Specifies the IP address of an SNTP server.
Note
If the switch is obtaining its IP address and subnet mask from a
DHCP sever, you can configure the DHCP server to provide the
switch with an IP address of an NTP or SNTP server. If you
configured the DHCP server to provide this address, then you do not
need to enter it here.
Poll Interval
Specifies the number of seconds the switch waits between polling the
SNTP or NTP server. The default is 600 seconds. The range is from 60
to 1200 seconds.
6. When you finish configuring the parameters, click the Apply buttons.
Note
If you enabled the SNTP client, the switch immediately polls the
SNTP or NTP server for the current date and time. (The switch
automatically polls the server whenever a change is made to any of
the parameters in this menu, so long as SNTP is enabled.)
7. To permanently save your changes to the SNTP client, click Save
Config.
