When installing new DLU`s do you only upload them to the Pub or do you need to upload to all the servers in the cluster


I have this problem too.

Hi CU55,

Jon is most correct (5 points for your good work Jon :) Here is some additional reference material;

The Node License Manager is the Publisher so it is the MAC Address that you provide for any licensing additions/requirements;

Uploading a License file

Use the following procedure to upload a license file to the Cisco CallManager server with the matching MAC address that is provided when requesting for a license file. For information about obtaining a license file see the "Obtaining a License File" section. The Cisco CallManager server where the license file is loaded takes on the functionality of the license manager.


***Note - Upload the license file only on the first node of Cisco CallManager cluster.




Step 1 Choose System > License > Upload License File.

The License File Upload window displays.

Step 2 The Existing License Files drop-down list box displays the license files that are already uploaded to the server.


Note Click View File to view the file content of any existing files.


Step 3 To choose a new license file to upload, click Upload License File.

The Upload File pop-up window displays.

Step 4 Browse and choose a license file to upload to the server.

Step 5 Click Upload License File.

After the upload process is complete, the Upload Result file displays.

Step 6 Click Close.

Step 7 In the License File Upload window, the status of the uploaded file displays.

From this good doc:


The Cisco CallManager server where the license file is loaded, assumes the functionality of a license manager.

The license manager serves as the logical component that keeps track of the licenses that the customer purchases and the licenses that customer uses. It refers to the processes that control the checkin and checkout of the licenses. It keeps track of the number of license units that are required for each phone type. The license manager has responsibility for issuing and reclaiming licenses, and detecting whether there is an overdraft of licenses.


Hope this helps!
