Time Protocols
SNTP: Viewing, Selecting, and Configuring
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.
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
2001:db8::215:60ff:fe79:8980
Disabling Time Synchronization Without Changing the SNTP
Configuration.
The recommended method for disabling time synchroniza-
tion is to use the
timesync
command.
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:
Figure 9-10. Example of SNTP with Time Sychronization Disabled
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.
Syntax:
no timesync
Halts time synchronization without changing your SNTP
configuration.
