SMCD3GN2 Wireless Cable Modem Gateway Administrator Manual
Using the SNTP Menu
The SNTP Settings menu lets you configure the Gateway to act as an SNTP client. SNTP is
a simplified, client-only version of NTP, a standard protocol used to synchronize system
clocks on computer systems. SNTP can be enabled on the Gateway to keep the Gateway’s
time accurate up to fractions of a second. The service is constantly updating the Gateway’s
clock, and can be used as a master time source for other systems on your network.
Note: While SNTP typically provides time within 100 milliseconds of the accurate
time, it does not provide the complex filtering and statistical mechanisms of NTP. In
addition, SNTP does not authenticate traffic. An SNTP client is more vulnerable to
misbehaving servers than an NTP client, and should only be used in situations
where strong authentication is not required.
To access the SNTP Settings menu, click Tools in the menu bar and then click the SNTP
Client submenu in the menu bar. Figure 82 shows an example of the menu and Table 32
describes the options you can select.
