<h1 class="topictitle1">SNTP server</h1>
|
||
|
|
<div><p>You can configure your iSeries™ server as an SNTP server. This
|
||
|
|
topic explains how you can use this feature to maintain time on your network.</p>
|
||
|
|
<p>You can use your iSeries server as an SNTP server. This enables you
|
||
|
|
to configure your iSeries to act as a time server for other devices.
|
||
|
|
Other SNTP clients check time by polling your iSeries SNTP server. If a client's time
|
||
|
|
values do not match the iSeries SNTP server time, a time adjustment begins.
|
||
|
|
The client's system time is adjusted until the required time value is reached.
|
||
|
|
This can be useful for maintaining time within a network.</p>
|
||
|
|
<p>In <a href="#rzaktserver__sntpclient">Figure 1</a>, the iSeries Server
|
||
|
|
A uses the SNTP server. In this situation, the coordinated universal time
|
||
|
|
(UTC) is retrieved from the iSeries server rather than being synchronized with
|
||
|
|
an external time source. This internal time value is sent to all SNTP client
|
||
|
|
systems (iSeries Server
|
||
|
|
B and Client A) connected to it.</p>

|
||
|
|
<p>In addition to using the SNTP server to synchronize clocks on the network,
|
||
|
|
you can concurrently run your iSeries as an SNTP client to obtain time
|
||
|
|
from an outside time source. For an example, refer to Scenario: Synchronize
|
||
|
|
clocks with iSeries server.</p>
