Time Protocols

SNTP: Viewing, Selecting, and Configuring

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 Global config level of the CLI, execute no timesync.
