What is NTP broadcast?

What is NTP broadcast?

An NTP server can also operate in a broadcast mode. Broadcast servers send periodic time updates to a broadcast address, while multicast servers send periodic updates to a multicast address. Using broadcast packets can greatly reduce the NTP traffic on a network, especially for a network with many NTP clients.

How do I connect to a NTP server?

1. Select the Use NTP to synchronize the system time check box.
2. To remove a server, select the server entry in the NTP Server Names/IPs list and click Remove.

4. Click OK.

What happens in broadcast mode in NTP server?

NTP Broadcast Mode. It is important to keep in mind that NTP broadcast mode usually yields less accuracy than the standard client/server mode. Normally an NTP client sends a request packets to a server, and the server sends a reply packet back to the client.

Where does the NTP network get its time from?

All NTP communication uses Coordinated Universal Time (UTC), which is the same as Greenwich Mean Time. An NTP network usually gets its time from an authoritative time source, such as a radio clock or an atomic clock that is attached to a time server.

How does a NTP server respond to a request?

Normally an NTP client sends a request packets to a server, and the server sends a reply packet back to the client. This allows the client to estimate and thus compensate the network delay for each individual packet exchange. See also Time Synchronization Accuracy With NTP .

Is the NTP server accessible by the client switch?

An NTP server must be accessible by the client switch. NTP uses the User Datagram Protocol (UDP) as its transport protocol. All NTP communication uses Coordinated Universal Time (UTC), which is the same as Greenwich Mean Time.
