Sntp: Selecting And Configuring - HP Aruba JL253A Management And Configuration Manual

Disabling the TimeP mode
Syntax:
no ip timep
Disables TimeP by changing the TimeP mode configuration to Disabled and prevents the switch from using it as
the time synchronization protocol, even if it is the selected Time Sync Method option.
Example:
If the switch is running TimeP in DHCP mode, no ip timep changes the TimeP configuration as shown below
and disables time synchronization. Even though the TimeSync mode is set to TimeP, time synchronization is
disabled because no ip timep has disabled the TimeP mode parameter.
Disabling time synchronization by disabling the TimeP mode parameter
switch(config)# no ip timep
switch(config)# show timep
Timep Configuration
Time Sync Mode: Timep
TimeP Mode : Disabled

The following table shows the SNTP parameters and their operations.

Poll Interval

Operation
The Default. SNTP does not operate, even if specified by the Menu interface Time Sync
Method parameter or the CLI timesync command.
Directs the switch to poll a specific server for SNTP time synchronization. Requires at
least one server address.
Directs the switch to acquire its time synchronization from data broadcast by any SNTP
server to the network broadcast address. The switch uses the first server detected and
ignores any others. However, if the Poll Interval expires three times without the switch
detecting a time update from the original server, the switch accepts a broadcast time
update from the next server it detects.
In Unicast Mode: Specifies how often the switch polls the designated SNTP server for a
time update.In Broadcast Mode: Specifies how often the switch polls the network
broadcast address for a time update.Value is between 30 to 720 seconds.
