Changing the SNTP Poll Interval.
This command lets you specify how
long the switch waits between time polling intervals. The default is 720
seconds and the range is 30 to 720 seconds. (This parameter is separate from
the poll interval parameter used for Timep operation.)
Syntax:
sntp poll-interval <30 . . 720>
For example, to change the poll interval to 300 seconds:
HP4108(config)# sntp poll-interval 300
Disabling Time Synchronization Without Changing the SNTP
Configuration.
The recommended method for disabling time synchroniza-
tion is to use the
timesync
command. This halts time synchronization without
changing your SNTP configuration.
Syntax:
no timesync
For example, suppose SNTP is running as the switch’s time synchronization
protocol, with
Broadcast
as the SNTP mode and the factory-default polling
interval. You would halt time synchronization with this command:
HP4108(config)# no timesync
If you then viewed the SNTP configuration, you would see the following:

Disabling the SNTP Mode.
If you want to prevent SNTP from being used
even if selected by
timesync
(or the Menu interface’s
Time Sync Method
param-
eter), configure the SNTP mode as disabled.
Syntax:
no sntp Disables SNTP by changing the SNTP mode configura-
tion to
Disabled
.
For example, if the switch is running SNTP in Unicast mode with an SNTP
server at 10.28.227.141 and a server version of 3 (the default),
no sntp
changes
the SNTP configuration as shown below, and disables time synchronization
on the switch.
