Changing the TimeP Poll Interval. This command lets you specify how
long the switch waits between time polling intervals. The default is 720
minutes and the range is 1 to 9999 minutes. (This parameter is separate from
the poll interval parameter used for SNTP operation.)
Syntax: ip timep dhcp interval < 1 . . 9999 >
ip timep manual interval < 1 . . 9999 >
For example, to change the poll interval to 60 minutes:
ProCurve(config)# ip timep interval 60
Disabling Time Synchronization Without Changing the TimeP
Configuration. The recommended method for disabling time synchroniza­
tion is to use the timesync command. This halts time synchronization without
changing your TimeP configuration.
Syntax:
no timesync
For example, suppose TimeP is running as the switch's time synchronization
protocol, with DHCP as the TimeP mode, and the factory-default polling
interval. You would halt time synchronization with this command:
ProCurve(config)# no timesync
If you then viewed the TimeP configuration, you would see the following:
