SNTP Unicast Time Polling with Multiple SNTP Servers

Figure 9-14. Example of TimeP with Time Sychronization Disabled

Disabling the TimeP Mode. Disabling the TimeP mode means to configure it as disabled. (Disabling TimeP prevents the switch from using it as the time synchronization protocol, even if it is the selected Time Sync Method option.)

Syntax: no ip timep

Disables TimeP by changing the TimeP mode configuration to Disabled.

For example, if the switch is running TimeP in DHCP mode, no ip timep changes the TimeP configuration as shown below, and disables time synchronization on the switch.

Even though the Time Sync Mode is set to Timep, time synchronization is disabled because no ip timep has disabled the TimeP Mode parameter.

SNTP Unicast Time Polling with Multiple SNTP Servers

When running SNTP unicast time polling as the time synchronization method, the switch requests a time update from the server you configured with either the Server Address parameter in the menu interface, or the primary server in a list of up to three SNTP servers configured using the CLI. If the switch does not receive a response from the primary server after three consecutive polling intervals, the switch tries the next server (if any) in the list. If the switch tries
