Hello,


i have tried to synchronise the CCM 6 cluster with NTP server, the problem iw when i verify at GUI, i found that the NTP was accessible, and when i search at CLI, it was different.

When i want to recover the system time, the time became unsynchronized between Publisher and Subscriber.


How can i recover the time accurately.


Thanks

Hi Driss,


Can you try this method;


NTP Servers


Ensure that external NTP server is stratum 9 or higher (1-9). To add, delete, or modify an external NTP server, follow this procedure:




--------------------------------------------------------------------------------


Note You can only configure the NTP server settings on the first node or publisher.



--------------------------------------------------------------------------------


Procedure



--------------------------------------------------------------------------------


Step 1 From the Cisco Unified Communications Operating System Administration window, navigate to Settings>NTP Servers.


The NTP Server Settings window displays.


Step 2 You can add, delete, or modify an NTP server:


•To delete an NTP server, check the check box in front of the appropriate server and click Delete.


•To add an NTP server, click Add, enter the hostname or IP address, and then click Save.


•To modify an NTP server, click the IP address, modify the hostname or IP address, and then click Save.




--------------------------------------------------------------------------------


Note Any change you make to the NTP servers can take up to five minutes to complete. Whenever you make any change to the NTP servers, you must refresh the window to display the correct status.



--------------------------------------------------------------------------------


Step 3 To refresh the NTP Server Settings window and display the correct status, choose Settings>NTP.




--------------------------------------------------------------------------------


Note After deleting, modifying, or adding NTP server, you must restart all the other nodes in the cluster for the changes to take affect.
