Time Protocols
SNTP: Viewing, Selecting, and Configuring
9-14
For example, to change the poll interval to 300 seconds:
ProCurve(config)# sntp poll-interval 300
Changing the Priority. You can choose the order in which configured serv-
ers are polled for getting the time by setting the server priority.
Syntax: sntp server priority <1 - 3> <ip-address>
Specifies the order in which the configured servers are polled
for getting the time. Value is between 1 and 3.
Note: Both IPv4 and IPv6 addresses can be entered. For more
information about IPv6 addresses, see the "IPv6 Configura-
tion Guide" for your switch.
For example, to set one server to priority 1 and another to priority 2:
ProCurve(config)# sntp server priority 1 10.28.22.141
ProCurve(config)# sntp server priority 2
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:
