Licensing¶
Before you can start a simulation, you must choose a valid Product Configuration and enter a valid Registration Token for Smart Licensing. To complete the required actions, log into the CML UI as a user with admin privileges using a supported web browser.
To apply a license, you must be must have deployed CML and already completed the Initial Set-up so that you have network access to the CML server’s management IP address from your local system.
Note
The Direct transport setting for Smart Licensing requires an active connection to the CSSM (Cisco Smart Software Manager). If your CML server does not have access to the CSSM and SLR (Specific License Reservation) is enabled in your Smart Account, you can instead license your CML server using SLR - Specific License Reservation.
Caution
If you want to delete, move, or redeploy a licensed CML VM, you must deregister the instance first. Only one CML deployment may be associated with each valid license.
Failure to deregister the CML server will result in a license that is considered to be in use with no way for you to release the license from CML itself. You will not be able to authorize a different CML server with the license in that state. See Licensing - Deregistration.
If you ever delete the CML VM without deregistering the CML server first, your license will be unusable until you manually delete the old CML instance from the Smart Licensing servers. In that case, follow the instructions at the end of the “out of compliance” answer in the CML FAQ.
Procedure
Connect to the CML server by navigating to its assigned IP address, which is shown in the VM’s console window.
Open https://nnn.nnn.nnn.nnn in your web browser.
Log in using the initial user credentials defined during initial deployment or any application account with administrator privileges.
After successful login, the Dashboard page is shown.
Click on (available only for an application account with administrator privileges) in the menu bar at the top of the Dashboard page.
Click View/Edit next to the Product Configuration label under Smart Software Licensing Status. Choose the Product License based on the Product Configuration label that was sent to you from Cisco Licensing or based on the SKUs available in your Smart Account. Click Save when done.
Click Register.
Paste the Registration Token in the provided text field, and click Register.
If you do not have your registration token, see Getting the Registration Token for Licensing.
Wait for your CML server to register itself with your Smart Account on the Cisco Smart Software Manager (CSSM).
The Registration Status will change to Registered.
If the Registration Status continues to show Registering, and the UI shows the Communication Timeout - Will Reattempt Automatically dialog, your CML server may be having trouble communicating with the Cisco Smart Software Manager (CSSM). Your CML server will continue to retry registration with the CSSM. If the issue persists for more than a few minutes, it may indicate a networking misconfiguration. Check your network settings and/or licensing transport configuration. When your CML server successfully registers, the Registration Status will change to Registered.
(CML-Enterprise only) If you have purchased any CML - Expansion Nodes licenses, click Choose Licenses.
The Choose Smart Licenses popup dialog will open.
(CML-Enterprise only) In the Choose Smart Licenses dialog, check the checkbox next to CML - Expansion Nodes.
The count for the CML - Expansion Nodes license becomes editable.
(CML-Enterprise only) Enter the number of CML - Expansion Nodes that you want to use on this CML installation.
(CML-Enterprise only) Click Save in the Choose Smart Licenses dialog.
The Choose Smart Licenses dialog will close, and your new CML - Expansion Nodes count will be shown in the Smart License Usage table.
Wait for your CML server to authorize the number and type of licenses that you have configured.
The License Authorization Status will change to Authorized after a few minutes. The Smart License Usage table will show the number of each license that it has authorized for use.
Note
Before you delete, move, or re-deploy a CML VM, you must deregister the CML server to release its license. Only one CML deployment may be associated with each valid license.
See Licensing - Deregistration for instructions on deregistering your CML server’s license.
After validation, your CML server is now ready to run simulations.
