2.15.11 Enabling/Disabling NTP Broadcasting
The NTP Broadcast mode is intended for one or a few servers and many clients.
SecureSync allows the NTP service to be configured to broadcast the NTP time only to the
network’s broadcast address at scheduled intervals.
NTP Broadcasting is used to limit the NTP service to only certain clients on the network.
NTP Broadcasting also reduces the amount of network traffic, but is therefore less accur-
ate since there is no compensation for cable delays, or other delays between NTP Server
and Client.
Note that NTP Broadcasting is rarely used and typically limited to special applications.
To enable NTP Broadcasting:
1.
Navigate to MANAGEMENT > NETWORK: NTP Setup.
2.
On the NTP Services panel, click the GEAR icon.
3.
The Edit NTP Services window will display. Check the Broadcast box.
4.
Select a Broadcast Interval. When NTP Broadcasting is selected, in addition to still
responding to NTP time requests sent from network appliances, SecureSync will
also send unsolicited NTP time packets to the local broadcast address at the Broad-
cast Interval specified by you.
