Enhancements in Release F.02.02
New Time Synchronization Protocol Options
•TimeP: DHCP or Manual
3. Configure the remaining parameters for the time protocol you selected.
The switch retains the parameter settings for both time protocols even if you change from one
protocol to the other. Thus, if you select a time protocol the switch uses the parameters you last
configured for the selected protocol.
Note that simply selecting a time synchronization protocol does not enable that protocol on the
switch unless you also enable the protocol itself (step 2, above). For example, in the factory-default
configuration, TimeP is the selected time synchronization method. However, because TimeP is
disabled in the factory-default configuration, no time synchronization protocol is running.
Disabling Time Synchronization
You can use either of the following methods to disable time synchronization without changing the
Timep or SNTP configuration:
■ In the System Information screen of the Menu interface, set the Time Synch Method parameter
to
None, then press [Enter], then [S] (for Save).
■ In the config level of the CLI, execute no timesync.
