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 or modem. It provides accuracies typically within a
millisecond on LANs and up to a few tens of milliseconds on WANs relative to
Coordinated Universal Time (UTC) through a Global Positioning Service
(GPS) receiver, for example. Typical NTP configurations utilize multiple
redundant servers and diverse network paths in order to achieve high
accuracy and reliability.
To configure NTP:
1. Select Option 3 from the main menu.
NTP Servers
===========
xxx.xxx.xx.x
Modify the NTP Servers <Add, Delete or eXit>[eXit]:
2. Enter the desired option and add or delete an NTP server or enter
X to return to the main menu.
Domain name resolution allows you translate and search domain names. The
Domain Name System (DNS) is a global network of servers that translate host
names like www.mycompany.com into numerical IP (Internet Protocol)
addresses, for example 24.62.13.19.
To configure domain name resolution:
1. Select Option 4 from the main menu.
Domain Name Resolution Configuration
====================================
1) DNS Servers
2) DNS Search Domains
