Mediatrix 1204 127
SNTP
The ipAddressConfigSntp group provides the configuration necessary for contacting a NTP/SNTP server.
If you are using a NTP or SNTP server (see “Chapter 20 - SNTP Settings” on page 239 for more details), the
DHCP server already has options that can be set to provide time server addresses, and the order in which
clients use them to attempt to discover servers.
The Mediatrix 1204 uses Option 42 to specify the IP address corresponding to the server that provides NTP/
SNTP (RFC 1769).
