Enabling Network Time Servers - Avaya S8400 Installing & Configuring

Chapter 4: Server configuration

Enabling network time servers

!
Important:
Avaya strongly recommends that you enable Network Time Protocol (NTP) and
Important:
configure at least one network time server. If a network time server is not used the
Date/Time settings on the server must be reset regularly, at least monthly, using
the Maintenance Web Interface. The network time strategy is determined by the
network administrator.
With NTP, you can specify one, two, or three network time servers to provide the accurate time
of day data to the clocks on the servers. The network time servers, in turn, get their source
timing from one of several highly accurate time services that are available on the Internet.
To use a network time server, the NTP service must be enabled. The Avaya Installation Wizard
prompts you to enable the NTP service. If you do not use the Installation Wizard, use the
Configure Server function on the Maintenance Web Interface to configure the network time
servers.
1. From the Maintenance Web Interface, under Server Configuration, click Configure
Server.
2. Click Continue on the Review Notices page and the Backup Up Data page.
3. On the "Specify how you want to use this wizard" page, select Configure individual
services and then click Continue.
4. In the menu on the left side of the Configure Server page, click Configure Timer Server.
5. Enter the NTS information on the Configure Time Server screen and click Change.
6. On the main menu, under Security, click Firewall.
7. In the "Output from Server" column, select ntp 123/udp.
Note:
It is not necessary to enable the "Input to Server" ntp service. If this service is
Note:
already enabled, you do not need to disable it.
When the Avaya Installation Wizard prompts you for information about the network time
servers, enter the DNS name or the IP address for the primary network time server and the
secondary and the tertiary time servers if any. If you enter a DNS name instead of an IP address
for the network time server, you must specify the IP address of the DNS server on the DNS/
DHCP web page. For more information, see
For more information about NTP, see RFC 958.
