Configuring NTP authentication in broadcast mode
Follow these instructions to configure NTP authentication in broadcast mode:
A broadcast client can synchronize to the broadcast server only when you configure all the required tasks on both the broadcast client and server.
If NTP authentication is not enabled on the client, the broadcast client can synchronize to the broadcast server no matter whether NTP authentication is enabled or not on the server.
Configuring NTP authentication for a broadcast client
Step | Command | Remarks |
|---|---|---|
1. Enter system view. | system-view | N/A |
2. Enable NTP authentication. | ntp-service authentication enable | By default, NTP authentication is disabled. |
3. Configure an NTP authentication key. | ntp-service authentication-keyid keyid authentication-mode md5 [ cipher | simple ] value | By default, no NTP authentication key is configured. Configure the same authentication key on the client and server. |
4. Configure the key as a trusted key. | ntp-service reliable authentication-keyid keyid | By default, the authentication key is not configured as a trusted key. |
Configuring NTP authentication for a broadcast server
Step | Command | Remarks |
|---|---|---|
1. Enter system view. | system-view | N/A |
2. Enable NTP authentication. | ntp-service authentication enable | By default, NTP authentication is disabled. |
3. Configure an NTP authentication key. | ntp-service authentication-keyid keyid authentication-mode md5 [ cipher | simple ] value | By default, no NTP authentication key is configured. Configure the same authentication key on the client and server. |
4. Configure the key as a trusted key. | ntp-service reliable authentication-keyid keyid | By default, the authentication key is not configured as a trusted key. |
5. Enter Layer 3 Ethernet interface view or VLAN interface view. | interface interface-type interface-number | N/A |
6. Associate the specified key with the broadcast server. | ntp-service broadcast-server authentication-keyid keyid | You can associate a non-existing key with the broadcast server. To enable NTP authentication, you must configure the key and specify it as a trusted key after associating the key with the broadcast server. |
