ProCurve Series 2300 and 2500 Switches Release Notes

200
Enhancements in Release F.02.02
New Time Synchronization Protocol Options
New Time Synchronization Protocol Options
Using time synchronization ensures a uniform time among interoperating devices. This helps you to
manage and troubleshoot switch operation by attaching meaningful time data to event and error
messages.
Formerly, TimeP was the only time protocol available for time synchronization in Series 2500
switches. Beginning with software release F.02.02, the switches also offer SNTP (Simple Network
Time Protocol) and a new
timesync command for changing the time protocol selection (or turning off
time protocol operation).
Notes
Although you can create and save configurations for both time protocols without conflicts,
the switch allows only one active time protocol at any time.
Time synchronization is no longer active in the factory default configuration. You must first
select the desired protocol (default: TimeP), and then enable it.
In the factory-default configuration for release F.02.02 and later, the time synchronization
method is set to TimeP, with actual TimeP operation disabled. (In earlier releases, TimeP
was enabled with DHCP for acquiring a TimeP server address).
If you configure SNTP operation in the switch, but later download a configuration created
using a pre-F.02.02 version of the software, the SNTP configuration will be replaced by the
non-SNTP time synchronization settings in the downloaded configuration file.
In the menu interface, the time protocol parameters have been moved from the "Internet (IP)
Service" screen to the "System Information" screen, and the menu path is now:

TimeP Time Synchronization
You can either manually assign the switch to use a TimeP server or use DHCP to assign the TimeP
server. In either case, the switch can get its time synchronization updates from only one, designated
Timep server. This option enhances security by specifying which time server to use.
