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.
10. Type 6 to select Poll Interval to specify the time interval between
queries to the SNTP server.
The following prompt is displayed:
Enter interval to poll SNTP server [60 to 1200] -> 600
Note
Selection 7, Last Delta, reports the last adjustment that had to be
applied to the system time; the drift in the system clock between two
successive queries to the SNTP server. You cannot change this
value.
11. Enter 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.
12. Type 2 to select SNTP Status to enable or disable the SNTP client.
The following prompt is displayed:
SNTP Status (E-Enabled, D-Disabled) ->
13. Type E to enable SNTP client software on the switch or D to disable
the NTP client software and press Return. The default is disabled.
After SNTP is enabled, the switch immediately polls the SNTP or NTP
server for the current date and time. (The switch also automatically
polls the server whenever a change is made to any of the parameters
in this menu, so long as SNTP is enabled.)
The Last Delta option in the menu displays the last adjustment that
was applied to system time due to a drift in the system clock between
two successive queries to the SNTP server. This is a read only field.
Option U, Update System Time, allows you to prompt the switch to poll
the SNTP or NTP server for the current time and date. You can use
this selection to update the time and date immediately rather than wait
for the switch’s next polling period. This selection has no effect if you
set the date and time manually.
14. After making changes, type R until you return to the Main Menu. Then
type S to select Save Configuration Changes.
