SNTP: Viewing, Selecting, and Configuring

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:

HPswitch(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:

HPswitch(config)# no timesync

If you then viewed the SNTP configuration, you would see the following:
