Network Time Protocol

PN 1275005-100 Rev E6

77

Chapter 9. Network Time Protocol

...synchronizing the system clock with an external reference

9.1. NTP Introduction

Network Time Protocol (NTP) synchronizes the clocks of computer systems communicating in packet-
switched, variable-latency data networks. NTP uses UDP port 123 for its transport layer. NTP avoids large
time jumps, reversals, and other discontinuities by adjusting the clock incrementally. It makes backward
time adjustments by slowing the system clock until the time is correct.

9.2. NTP Server Hosts

NTP requires at least one "upstream" server to synchronize the local time. Add an NTP server host to
the EM316LNXNM with the "

ntp-server host A.B.C.D

" command from the main configuration

context. "

A.B.C.D

" represents the IP address of the added NTP server.

fiberdriver# configure terminal

fiberdriver(config)# ntp-server host A.B.C.D

fiberdriver(config)#

Use one of the many public servers that offer NTP if you do not have any local NTP servers. Avoid using
more than five servers.

Check that the NTP servers are added correctly with the "

show ntp-server hosts

" command from

the main configuration context.

fiberdriver(config)# show ntp-server hosts

ntp-server host 192.168.14.98

ntp-server host 192.168.14.106

ntp-server host 10.1.1.8

fiberdriver(config)#

9.3. Enabling/Disabling NTP

NTP is disabled by default. After adding the NTP server hosts and verifying them, enable NTP from the
main configuration context with the "

ntp

" command. Add the server hosts before enabling NTP so that

the system can set the time most accurately when NTP starts up.

fiberdriver(config)# ntp

fiberdriver(config)#

Disable NTP at any time with the "

no ntp

" command from the main configuration context. The

EM316LNXNM clock may gradually gain or lose accuracy without synchronization.

fiberdriver(config)# no ntp

fiberdriver(config)#
