Setting Up Network Time<br />

Protocol<br />

About this appendix This appendix provides a brief introduction to Network Time Protocol<br />

(NTP) and describes how to set up NTP on the <strong>Sidewinder</strong> <strong>G2</strong>. This<br />

appendix covers the following topics:<br />

“Overview” on page B-1<br />

“Configuring NTP on a <strong>Sidewinder</strong> <strong>G2</strong>” on page B-5<br />

“References” on page B-8<br />

Overview NTP provides a way to synchronize all clocks on a network, or to<br />

synchronize the clocks on one network with those on another<br />

network. You may find NTP useful in the following situations:<br />

When your internal network includes a system that already<br />

provides time for the rest <strong>of</strong> your network.<br />

When, for time-critical services, it is important to synchronize your<br />

network with a more accurate chronometer on an external<br />

network.<br />

Important: If exact synchronization is not important to your site, you may ignore NTP<br />

entirely. NTP is not automatically enabled during <strong>Sidewinder</strong> <strong>G2</strong> installation, and is active<br />

only if you configure and enable it as described later in this appendix.<br />

This release <strong>of</strong> the <strong>Sidewinder</strong> <strong>G2</strong> is compatible with NTP versions 1,<br />

2, and 3. Version 3 is the preferred version and is the default on the<br />

<strong>Sidewinder</strong> <strong>G2</strong>.<br />
