Enabling Network Time Servers
!
Important:
Important:
Avaya strongly recommends enabling Network TIme Protocol (NTP) and
configuring at least one network time server. If a network time server is not used,
the Date/Time settings on the media server should be reset regularly (at least
monthly), using the Maintenance Web Interface. The network time strategy
should be determined by the network administrator.
Enabling Network Time Protocol allows you to specify one, two, or three network time servers to
provide accurate time-of-day data to the clocks on the media servers. The network time servers,
in turn, get their source timing from one of several highly accurate time services available on the
Internet.
To use a network time server, the NTP service must be enabled. The Avaya Installation Wizard
prompts for enabling the NTP service.
If you are not using the Installation Wizard, or if you want to see if NTP is enabled, follow these
steps:
1. Open the Maintenance Web Interface
2. Click on the Firewall link under Security.
3. Enable ntp 123/udp in the "Output from Server" column by clicking on the checkbox.
Note:
Note:
It is not necessary to enable the "Input to Server" ntp service but if it is already
enabled, you don’t have to disable it.
In the next section, Using the Avaya Installation Wizard (IW) on page 161, the Avaya Installation
Wizard prompts for information about network time servers. When prompted, enter the DNS
name or IP address for the primary (and secondary and tertiary, if any) network time server. If
you enter a DNS name instead of an IP address for the network time server, the DNS server IP
address must be specified. You are prompted for this information by the Installation Wizard.
If you are not using the Installation Wizard, the network time servers can be configured using
the Configure Server function on the Maintenance Web Interface.
For detailed information about NTP, see RFC 958.
