Managing licenses

License-based features require a license to run on your device.

This chapter describes how to license a feature, transfer a license between devices, remove a license, and manage the license storage space.

Licenses include trial licenses and formal licenses. Trial licenses typically have time limits. Purchase and install a formal license for a license-based feature before its trial license expires, so that the feature is still usable.

License types

The following types of licenses are available depending on validity period:

·     Permanent—A permanent license is always valid and never expires.

·     Days restricted—A license valid for a limited period in days, for example, 30 days.

Locking methods

The following locking methods are available:

·     Device locked—A license can be installed only on the DID-specific device. The license takes effect on any MPU in the device even after an MPU replacement.

·     MPU locked—A license can be installed only on the DID-specific MPU. The license takes effect on the MPU even after the MPU is moved to a different device.

Restrictions and guidelines

General restrictions and guidelines

When you manage licenses, follow the general restrictions and guidelines:

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

·     Trial licenses and expired formal licenses cannot be uninstalled. Expired licenses remain in the license storage area unless you compress the license storage area.

·     Licenses cannot be installed if the license storage area is not sufficient. Before registering licenses, use the display license feature command to identify the number of available licenses. Do not register licenses more than the available number.

·     When installing a license, the system also searches the storage media for a matching feature package. When it finds a matching package, it stops searching and installs the package.

·     When uninstalling a license, the system checks whether the feature package for the license is running. If it is running, the system uninstalls the package automatically.

·     If you cannot obtain or re-register the activation file due to problems such as operating system and browser errors, contact H3C Support.

License file safety

When you manage licenses, follow these restrictions and guidelines for license file safety:

·     Save and back up the obtained activation file or license key in case of loss.

·     If you use FTP to transfer the .id file and the activation file, use the Binary mode.

·     Do not open and edit the .id file or activation file to avoid file corruption.

·     Do not modify the name of the .id file or activation file to avoid licensing error.

·     Do not delete or move files in the flash:/license directory on a device. The license management feature uses this directory for license management. An incorrect file operation can cause problems. For example, if you delete an activation file that is usable or in use, the related feature will not function correctly. If a file is missing or corrupted, use the copy command to copy its backup file to the directory to recover the license. If the state of the recovered license is In use but not all licensed features can function, reboot the device. To verify the license state, use the display license command.

Licenses for different device types

When you register and install licenses, follow these restrictions and guidelines:

·     Install one license for the feature on each member in the fabric. Make sure the SN and DID used for registering the feature license matches the current SN and DID of the specified member device.

·     Make sure the licenses installed on the members are the same.

·     A registered license takes effect on the member device where it is installed, and it is effective even after the member device joins another IRF fabric.

Compressing the license storage



·     Compressing the license storage deletes expired licenses, uninstalled licenses, and Uninstall files. Back up the Uninstall files before you compress the license storage.

·     The DID changes each time the license storage is compressed. Before performing a compression, make sure all activation files generated based on the old DID have been installed. They cannot be installed after the compression.


When the value for the Total field equals that of the Usage field from the output of the display license feature command, the license storage area is full. To ensure sufficient storage space for installing new licenses, compress the license storage area.

To compress the license storage:




1.     Enter system view.


2.     Compress the license storage.

Registering and activating a license

Make sure you have purchased a license for the first registration or an upgrade license for add-on nodes, add-on features, or time extensions.

To register and activate a license:




1.     Identify the number of available license storage entries.

2.     (Optional.) Compress the license storage if the free license storage is not sufficient for licenses to be activated.

See "Compressing the license storage."

3.     Obtain the SN string and the .id file on the member device.

4.     Use FTP or TFTP to transfer the .id file to the PC.


5.     Identity the license key on your license.


6.     Access http://www.h3c.com.hk/Technical_Support___Documents/Product_Licensing/, and select Register the First Time or Register Upgrade Licenses from the navigation tree.


7.     Select the product category and use the license key, SN, and DID to register the license.


8.     Download the activation file to the member device.


9.     Enter system view.


10.     Install the activation file.

Transferring a license

You can transfer a license from one device to another if its activation file has not expired. If the activation file has expired, the license is not transferrable.

To transfer a license:





1.     Enter system view on the source device.



2.     Uninstall the activation file.

license activation-file uninstall file-name slot slot-number

When an activation file is uninstalled, the system creates an Uninstall file. This file is required when you register the license for the target device.

The uninstallation action does not delete license data from the license storage area. To free storage space, you must compress the license storage (see "Compressing the license storage").

3.     Obtain the Uninstall key of the source device.

4.     Access the target device and display SN and DID information.

5.     Access http://www.h3c.com.hk/Technical_Support___Documents/Product_Licensing/, and use the target device's SN and DID information and the source device's Uninstall key to generate a new activation file.



6.     Download the new activation file to the target device.



7.     Install the activation file on the target device.
