3 Configuring Network Time
Protocol (NTP)
The 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 accura-
cies 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 Proto-
col and how to configure it through the Command Line Interface (CLI). CLI commands are used in the
configuration examples; for more details about the syntax of commands, see the
OmniSwitch CLI Refer-
ence 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 3-8 .
•
Selecting an NTP server for the NTP client and modifying settings for communicating with the server.
See
“NTP Servers” on page 3-9 .
•
Enabling authentication in NTP negotiations. See “Using Authentication” on page 3-10 .
