SNTP server configuration

Last Updated : Oct 13, 2023 |

Simple Network Time Protocol (SNTP) server is a time maintenance application. Avaya J100 Series IP Phones use the SNTP mechanism for time-synchronization. The phones the network time server that runs on the devices.

SNTP specifies the IP address or DNS of the network time server. You can configure SNTP using one of the following methods listed in the table:

No

Method

Notes

1

DHCP option 42

You can configure DHCP option 42 that provides SNTP IP address list. See DHCP options in Related links.

2

46xxsettings.txt file

Use the settings file for configuring date and time using SNTP parameter. See SNTP parameter in Related links.

3

Administration menu on the phone

Use the administration menu to update the SNTP server information on the phone. See IP configuration field description in Related links.

4

Web interface of the phone

Use the IP Configuration field for updating SNTP server information using the web interface of the phone. See Ethernet settings field descriptions in Related links.

On Avaya J100 Series IP Phones, the value of SNTPSRVR parameter can be a comma-separated list of SNTP server addresses, which can be IPv4 or IPv6 addresses. This parameter has following default values:

0.avaya.pool.ntp.org,1.avaya.pool.ntp.org,2.avaya.pool.ntp.org, 3.avaya.pool.ntp.org

If these servers are not reachable, you can configure the phone with an alternate list of SNTP servers. Set the SNTPSRVR parameter value in the 46xxsettings.txt file to ntpserver-1,ntpserver-1,ntp-server-2. The parameter provides IP address or Fully Qualified Domain Name (FQDN) of the required NTP servers. Specify the correct SNTPSRVR to prevent any delay caused by the phone waiting for NTP server timeouts.

Note:

The phone can obtain the date and time from an NTP server. If you do not configure an NTP server or if the phone cannot access the NTP server, the phone uses a SIP server. In CCMS mode in the IP Office environment, if the phone connects to a SIP server to obtain the date and time values and displays the incorrect values, the SIP server might have the incorrect date and time configuration.
