Add NTP reference in CCM 6.1

Answered Question
Feb 1st, 2008

The docs make it look too easy: 'utils ntp config' seems like it should change the NTP references, but all it does is give me the following status:

"This node is configured to synchronize with its hardware clock".

Is there any way to set the server up with additional external NTP references? I don't believe that using the GUI to add a phone reference is what I need... would appreciate any ideas!

I have this problem too.

Hi Matthew,

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.

Thanks man! I'm already missing 4.1.3; in those good old days (last month), all I needed was "administration" and "servicability"... none of this fancy OS Administration stuff.

Seriously, thanks for a very concise and helpful post.

Hi Matthew,

You are most welcome my friend! This stuff doesn't seem to get any easier does it :)

Best of luck and continued success,

Rob
