TimeP: Viewing, Selecting, and Configuring
Time Protocols
For example, suppose:
■Time synchronization is configured for SNTP.
■You want to: 
1.View the current time synchronization.
2.Select TimeP as the time synchronization mode.
3.Enable TimeP for DHCP mode.
4.View the TimeP configuration.
The commands and output would appear as follows:
Figure 8-15.  Example of Enabling TimeP Operation in DHCP Mode
Enabling Timep in Manual Mode. Like DHCP mode, configuring TimeP for 
Manual mode enables TimeP. However, for manual operation, you must also 
specify the IP address of the TimeP server. (The switch allows only one TimeP 
server.) To enable the TimeP protocol:
Syntax:timesync timepSelects Timep.
ip timep manual <ip-addr>Activates TimeP in Manual mode with a  spec-
ified TimeP
server.
no ip timepDisables TimeP.
Note
To change from one TimeP server to another, you must (1) use the no ip timep 
command to disable TimeP mode, and then reconfigure TimeP in Manual 
mode with the new server IP address.
show timep displays the TimeP configuration and also shows 
that SNTP is the currently active time synchronization mode.
