Changing the SNTP Poll Interval.
Syntax: sntp poll-interval < 30 . . 720 >
Specifies 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.)
For example, to change the poll interval to 300 seconds:
ProCurve(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 to avoid changing the switch’s SNTP
configuration.
Syntax: no timesync
Halts time synchronization without changing the switch’s
SNTP configuration
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:
ProCurve(config)# no timesync
If you then viewed the SNTP configuration, you would see the following:
