Managing licenses

About licenses

License-based features require licenses to run on your device.

License types

Licenses include trial licenses and formal licenses. Trial licenses typically have time limits. After a trial license expires, the license-based feature is not available unless you purchase and install a formal license for the feature.

Licenses for different device types

In an IRF fabric, only the license on the master device takes effect. The total number of concurrent online APs cannot exceed the sum of AP count allowed by licenses on the master device. For example, three member devices form an IRF fabric. The license on member device 1 allows a maximum of 10 concurrent online APs, the license on member device 2 allows 5, and no license is installed on member device 3. If member device 2 is the master device, a maximum of 5 concurrent online APs are allowed. If member device 3 becomes the master device, no AP is allowed to go online.

As a best practice, install licenses on all member devices to ensure service continuity after a master/subordinate switchover.

If a member device installed with a license leaves the IRF fabric, its license is available for a 30-day grace period in the original IRF to ensure service continuity. Meanwhile, the license continues to take effect on the leaving device.

Restrictions: Hardware compatibility with license management

The following switches do not require licenses for the unified wired and wireless access controller feature because they do not support this feature:

·     S6520X-26MC-SI and S6520X-26MC-UPWR-SI switches.

·     S6520-22SG-SI and S6520-30SG-SI switches.

·     S5000-EI switch series.

Restrictions and guidelines: License management

Management operation

Make sure no one else is performing license management tasks on the device you are working with.

Activation file and DID file operations

When you manage DID files or activation files, follow these restrictions and guidelines:

·     Do not open and edit the files to avoid file corruption.

·     Do not modify the names of the files to avoid licensing error.

·     For licensed features to function correctly, do not delete files that are usable or in use in the flash:/license directory. The license management feature uses this directory for license management.

License consistency in an IRF fabric

Only the unified wired and wireless AC licenses on the master device take effect. The licenses on the subordinate devices are not effective. As a best practice, install licenses on all member devices to ensure service continuity after a master/subordinate switchover.

The maximum number of concurrent online APs in the whole IRF fabric cannot exceed the following limits:

·     The sum of AP count defined by licenses on the master device.

·     The upper limit on the AP count supported by the master device. The supported upper limit varies by device type.

For licensed features to function correctly in an IRF fabric, make sure all IRF member devices are installed with the same licenses.

License management tasks at a glance

To manage licenses, perform the following tasks:

1.     Identifying the license storage

2.     (Optional.) Compressing the license storage

3.     Obtaining required information for license registration

4.     Registering a license

5.     Installing a license

6.     Managing installed licenses

¡     Uninstalling a license

¡     Transferring a license

¡     Recovering an activation file

 

Identifying the license storage

To identify the license storage, execute the following command in any view:

display license feature

From the command output, view the Total and Usage fields to examine whether the remaining license storage is sufficient for installing new licenses. If the remaining license storage is not sufficient, compress the license storage.

Compressing the license storage

About this task

Compress the license storage to delete expired and uninstalled license information to ensure sufficient storage space for installing new licenses.

Restrictions and guidelines

The compression operation clears expired licenses and uninstalled licenses that are installed by using activation files or activation keys.

If uninstalled licenses or expired licenses exist on the device, the compression operation will make the DID change. Before performing a compression, make sure all licenses registered with the old DID have been installed. You will be unable to install such licenses after the compression.

Procedure

1.     Back up the Uninstall keys of uninstalled licenses.

When you uninstall an unexpired formal license, an Uninstall key is created. The Uninstall key is required for transferring the license.

2.     Make sure all licenses generated based on the old DID have been installed.

3.     Enter system view.

4.     Compress the license storage.

Obtaining required information for license registration

1.     Identify whether the required features need to be licensed on the device.

Execute the following command in any view:

display license feature

2.     Execute the following command in any view to display the current license status.

1.     Use FTP or TFTP to upload the file to the Web client, such as PC.

If FTP is used to transfer the .did file, use the Binary mode.

2.     Back up the license key in case of loss.

Registering a license

About registering a license

License registration has the following procedures:

·     Registering licenses for the first time—Register a license for a device that has not previously been registered.

·     Registering upgrade licenses—Register licenses for capacity expansion, feature enhancement, or a time extension. This procedure is also applicable to the scenario that you register a new license for a device that has expired or uninstalled licenses.

If you do not know which registration procedure should be used, select registering licenses for the first time. If the selection is not correct, the website will display messages for the correct registration choice after you enter the required information.

Uninstalling a license

About license uninstallation

Perform this task to uninstall an unexpired formal license when the license remains unused for a while or needs to be transferred to another device.

After uninstallation, Uninstall keys are generated, which will be used for license transfer.

Restrictions and guidelines for license uninstallation

Back up the Uninstall key of a license properly for the license's next use.

Trial licenses cannot be transferred. Uninstall a trial license does not create any uninstallation information.

Expired licenses cannot be uninstalled.

Once the activation file is uninstalled, you cannot install it on the device again. To recover the license on the device, perform the following steps:

1.     Contact the customer service to unbind the license from the device.

2.     Use the license key to apply for a new activation file for the device.

3.     Install the new activation file on the device.

Uninstalling an activation file
