11 Configuring Network
Time Protocol (NTP)
Network Time Protocol (NTP) is used to synchronize the time of a computer client or server to another
server or reference time source, such as a radio or satellite receiver. It provides client time accuracies
within a millisecond on LANs, and up to a few tens of milliseconds on WANs relative to a primary server
synchronized to Universal Coordinated Time (UTC) (via a Global Positioning Service receiver, for example).
In This Chapter
This chapter describes the basic components of the OmniSwitch implementation of Network Time Protocol
and how to configure it through Command Line Interface (CLI). CLI commands are used in the
configuration examples; for more details about the syntax of commands, see the OmniSwitch AOS Release
8 CLI Reference Guide.
Configuration procedures described in this chapter include:
• Enabling the NTP client and selecting the NTP mode. See “Configuring the OmniSwitch as a Client”
on page 11-9.
• Selecting an NTP server for the NTP client and modifying settings for communicating with the server.
See “NTP Servers” on page 11-10.
• Enabling authentication in NTP negotiations. See “Using Authentication” on page 11-12.
