ntp-service broadcast-server
Function
The ntp-service broadcast-server command configures the local device to work in NTP broadcast server mode.
The undo ntp-service broadcast-server command removes the device from the NTP broadcast server mode.
By default, the broadcast server mode is not configured.
Format
ntp-service broadcast-server [ version number | authentication-keyid key-id ] *
undo ntp-service broadcast-server
Parameters
| Parameter | Description | Value |
|---|---|---|
| version number | Indicates the NTP version number. If this parameter is not specified, the version number is a default value. |
The value is an integer that ranges from 1 to 4. The default value is 3. |
| authentication-keyid key-id | Indicates the authentication key number used to transmit
a message to broadcast clients. If this parameter is not specified, authentication is not performed. |
Key ID is an integer and ranges from 1 to 4294967295. |
Usage Guidelines
On a synchronization subnet, when the IP address of a server or a symmetric peer is not determined, or when the clocks on a large number of devices need to be synchronized on the network, you can implement clock synchronization by configuring the broadcast mode.
On a specified interface on the broadcast server, run the ntp-service broadcast-server command to configure an interface on the local device to send NTP broadcast packets. When the local device automatically runs in the broadcast server mode, the device can send synchronization packets to a broadcast client. For the configuration of the broadcast client, see the ntp-service broadcast-client command.
When the configuration is complete, you can run the display ntp-service sessions command to obtain information about sessions between the broadcast server and the client.
