Time Protocols

SNTP: Viewing, Selecting, and Configuring

Changing the SNTP Poll Interval.

Syntax:

sntp < 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 inter
val 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.

Syntax:

no timesync

Halts time synchronization without changing your 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:

ProCurve(config)# show sntp

SNTP Configuration

Time Sync Mode: Disabled
SNTP Mode : Broadcast
Poll Interval (sec) [720] : 720
