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:

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.

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

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