The following Avaya switch platforms can use the SNTP software on the platform OS to directly synchronize the switch clock to the UTC time from an Internet Time Server:
Avaya IP600
DEFINITY One
Avaya S8000 Media Server
Avaya S8300 Media Server
Avaya S8700 Media Server
The platforms listed include either Red Hat Linux or Windows 2000 as the platform OS. The following conditions are in effect for the SNTP configuration on the systems:
For Linux platforms, configure the IP addresses for a minimum of three different Internet Time Servers.
For Linux platforms, go to the following Web sites for information on how to obtain NTP/SNTP software:
http://www.ubr.com/clocks/timesw/timesw.html
http://www.ntp.org/software/index.html
Linux platforms support the authentication/encryption mode provided in NTP/SNTP version 3 or later support. This capability is not enabled by default.
Windows 2000 platforms can use only one SNTP client (W32Time), which limits UTC polling to one Internet Time Server IP address at a time. For more information, see the Microsoft Windows 2000
documentation. Search for the keywords Window Time Service.
Windows 2000 platforms use the W32Time service for SNTP functions. This service does not support an authentication/encryption mode for the SNTP protocol.
W32Time service allows optional polling of a Microsoft network domain controller as the primary time server. Avaya does not support this configuration.
