Overview

H3C offers licensing options for you to deploy features and expand resource capacity on an as needed basis. To use license-based features, you purchase licenses from H3C and install the licenses.

License types

H3C offers preinstalled, trial (or temporary), and formal licenses. Support for preinstalled and trial licenses varies by product. For more information about the license options available for a product, see the license matrixes document for that product.

Preinstalled licenses

Preinstalled licenses are built into a system and are available for use on initial startup of the system. Users do not need to activate them.

A preinstalled license is typically time limited and cannot be uninstalled or transferred.

When a preinstalled license expires, the license-based feature becomes unavailable. To continue to use the feature, you must purchase and install a formal license for it.

Trial licenses

Trial licenses are provided for you to verify the functionality of premium features so you can make an educated purchase decision.

A trial license is time limited and cannot be uninstalled or transferred.

When a trial license expires, the license-based feature becomes unavailable. To continue to use the feature, you must purchase and install a formal license for it.

To obtain a trial license for a feature:

1.     Contact your H3C sales representative or technical support.

2.     Register the trial license key with H3C License Management Platform to obtain an activation file.

3.     Install the activation file to activate the feature.

Formal licenses

To gain most from a license-based feature, purchase a formal license for it.

Formal licenses are available with different validity periods and their support for uninstallation and transfer of formal licenses depends on product model. For more information, see the license compatibility information document for the product.

To install a formal license for a feature:

1.     Purchase a software license certificate through an official channel.

2.     Access H3C License Management Platform, and then enter the license key in the certificate and the required device information to obtain an activation file.

3.     Install the activation file in the target system.

Concepts

The following information describes the basic concepts that you might encounter when you register, install, and manage licenses.

H3C License Management Platform

H3C License Management Platform provides product licensing services for H3C customers. You can access this system to obtain license activation file, transfer licenses, or remove the device and license binding for an uninstalled license.

H3C License Management Platform is accessible at https://new-licensing.h3c.com/website/anonymous/navIndex/en-US/activate/input-license.

Software license certificate

A software license certificate allows users to use a license-based feature. It contains license key, license capacity, and other information.

License key

A license key uniquely identifies a license.

·     To obtain a formal license key, purchase a software license certificate. The authorization serial number in the software license certificate is the license key.

·     To obtain a trial license key, contact your H3C sales representative or H3C technical support. Support for trial licenses depends on the device model. For more information, see the license compatibility information document for the product.

Device serial number

A device serial number (SN or S/N) is a barcode that uniquely identifies a device. It comes with the device and must be provided when you request a license in H3C License Management Platform.

Device ID (DID) and DID file

A DID is a string of characters that uniquely identifies a hardware device. A DID file stores the DID and other information. The product comes with a DID or DID file. You must provide the DID or DID file when you request a license for the device on H3C License Management Platform.

Activation file

An activation file (AF) binds a license to a system.

To use a license-based feature on a system, you must perform the following tasks:

1.     Use the license key and the system’s SN information to obtain an activation file from H3C License Management Platform.

2.     Install the activation file on the system.

Uninstall key and Uninstall file

When you uninstall an activation key or file, the system generates an Uninstall key (UK) or Uninstall file (UF), respectively. This information proves that the license and system binding has been removed. You must provide this information when you transfer an unexpired license from one system to another.

License storage

License storage is a persistent storage of fixed size for storing licensing information. This information includes the licensing state, licensing time, Uninstall key or file, and other related information.

Data in the license storage persists through reboot. This ensures licensing accuracy and continuity.

License sharing

License sharing enables the member devices in a multichassis system to share their licenses for a feature. For more information about license sharing, see "Appendix  A License sharing."

Online automatic installation for local licensing

About license online automatic installation

License online automatic installation simplifies license installation. You can complete license installation on the local Web interface without logging in to H3C License Management Platform.

To install a license online automatically, perform the following tasks:

1.     Obtain a license key for the license.

2.     Configure network settings on the device to ensure that the device can access the public network and connect to H3C License Management Platform.

3.     Configure license online automatic installation on the Web interface. The device will automatically connect to H3C License Management Platform in the background to request an activation file and install the activation file on the device.

Restrictions and guidelines

·     License online automatic installation is supported only on the Web interface in expert mode.

·     Support for license online automatic installation depends on the device model. To identify whether the device supports this feature, log in to the Web interface of the device in expert mode and go to the System > System > License Management > License configuration page. If you can select online automatic installation or local manual installation, the device supports license online automatic installation.

·     Make sure the device can access the public network and connect to H3C License Management Platform. If the device acts as a gateway or acts as an AC in hairpin mode, it obtains an IP address through DHCP by default. You can configure PPPoE, static IP address, and static routing to ensure that the device can access the public network through the upstream network.

Installing a license

Installation workflow

The procedures for installing formal licenses and trial licenses are the same except the channels to obtain license keys. Figure 1 shows the workflow to install a license online automatically.

Figure 1 License installation workflow

 

 

Obtaining a license key

CAUTION

CAUTION:

After you obtain a license key, back it up and keep the backup license key in a safe place for future use.

For some device models, you must make sure the number of AP licenses installed on a device does not exceed the number of AP license allowed on the device to ensure successful license installation. MSG series multiservice gateways and WAC and MAK series access controllers are examples of such device models.

 

Obtaining a formal license key

1.     Log in to the Web interface of the device, click the system view tab at the bottom of the page, and then select System > License Management from the left navigation pane. On the Licenses and features tab, identify features that require licensing.

Figure 2 Sample from the Web interface

 

2.     To use a license-based feature, purchase a software license certificate for it. The authorization serial number in the software license certificate is the license key.

Obtaining a trial license key

If you need a trial license key to verify the functionality of a feature before you making a purchase decision, contact your H3C sales representative or H3C Support.

Installing a license

1.     Log in to the Web interface of the device.

2.     Click the system view tab at the bottom of the page.

3.     From the left navigation pane, select System > License Management.

About local licensing

Local licensing requires license activation device by device. It is applicable to small-sized networks.

To install a license on a device:

1.     Obtain the license key and the SN of the device.

2.     Access H3C License Management Platform to request an activation file based on the license key and the device's SN.

3.     Install the activation file on the device to activate the license.

The activation file for a license is device locked. You cannot install the activation file for one device to activate the license on another device.

Figure 6 Local licensing procedure

 

Restrictions and guidelines

Management operation restrictions and guidelines

·     Purchase licenses from H3C authorized channels.

·     To identify the validity periods of the licenses that have been installed on the device, execute the display license command or do that from the Web interface. If the license for a feature is time limited, install a new license for the feature before the old license expires.

Figure 7 Sample output from the display license command

 

Figure 8 Sample from the Web interface

 

·     Licenses are typically device locked. To ensure a successful licensing, use the following licensing guidelines:

a.     When you purchase a license certificate, verify the following items:

-     Make sure the license is compatible with the target device.

-     Make sure its licensed functionality and capacity meet your requirements.

b.     When you obtain an activation file, make sure the provided license key and hardware information are correct.

c.     Install the activation file on the correct target device.

·     Make sure no one else is performing license management tasks while you are managing licenses on the device.

·     Unless otherwise stated, all character strings entered on H3C License Management Platform are case sensitive. As a best practice to ensure a successful licensing, copy and paste license keys, device SNs, and values for other critical fields as long as possible.

File operation restrictions

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

·     To avoid licensing error, do not modify the file name or edit the file content.

·     Before you install an activation file, download the activation file to the storage media of the device such as flash memory. When installing an activation file, the device automatically copies the activation file to the license folder in the root directory of the storage media. The license folder stores important files for licensing. For licensed features to function correctly, do not delete or modify the license folder or the files in this folder.

Registering and installing a license

The procedures for registering and installing formal licenses and trial licenses are the same.

Figure 9 shows the licensing procedure.

Figure 9 Licensing procedure

 

Licensing requirements

Single-node deployment

Licenses for fixed-port devices are device locked (also called chassis locked). You purchase, register, and install licenses on a per-device basis.

Licenses for access controller modules are module locked. You purchase, register, and install licenses on a per-module basis. If you remove an access controller module from Device A and then install it on Device B of the same series, the licensed features on Device A do not take effect and the licensed features on Device B can operate correctly before the licenses expire.

Licenses for unified wired and wireless modular devices are device locked or MPU locked, depending on the device series. To identify the license locking type, execute the display license feature command.

·     If the command output does not contain slot fields, the license is device locked. Use the following guidelines:

¡     You purchase licenses and install their activation files on a per-device basis.

¡     When you install an activation file, the system automatically copies the activation file to all MPUs of the device.

-     The licensed feature can operate correctly after you remove one of the MPUs.

-     If you replace one of the MPUs, the system automatically copies all activation files to the new MPU to make sure the licensed features can operate correctly after an active/standby switchover.

-     If you are replacing both MPUs at the same time, back up the activation files. After the replacement, you must copy the activation files back to the new active MPU for the licensed features to continue to take effect. The system will automatically copy the activation files to the standby MPU.

Figure 10 Command output without the slot field

 

·     If the command output contains slot fields, in Slot xx or Chassis xx Slot xx format, the licenses are MPU locked. Use the following guidelines:

¡     You purchase, register, and activate licenses of the same specifications for each MPU in the device. This ensures that the license-based features can continue to take effect after an active/standby switchover.

¡     If you move the MPUs to another device, the license-based features can continue to take effect on the destination device as long as they are still valid. To have the license-based features continue to take effect on the source device, you must purchase, register, and activate new licenses for the new MPUs.  

Figure 11 Command output with slot fields

 

1+N node redundancy deployment

In a 1+N node redundancy deployment, only the licenses installed on the current master node are used if the deployment does not support license sharing. For a license-based feature to take effect after a master/standby switchover, you must purchase, register, and install a license of the same specification on each of the member node. The license installation requirements and license installation procedures are the same across the member devices. If the deployment supports license sharing, see "Appendix  A License sharing."

Obtaining a license key

After you obtain a license key, back up it and keep the backup license key in a safe place for future use. For some device models, you must make sure the number of AP licenses installed on a device does not exceed the number of AP license allowed on the device to ensure successful license installation.

Obtaining a formal license key

1.     Obtain a formal license key from the CLI or Web interface:

a.     Log in to the CLI of the device and execute the display license feature command in any view to identify features that require licensing.

Figure 12 Sample output from the display license feature command

 

b.     Log in to the Web interface of the device, click the system view tab at the bottom of the page, and then select System > License Management > Licenses and features from the left navigation pane to identify features that require licensing.

Figure 13 Sample from the Web interface

 

2.     To use a license-based feature, purchase a software license certificate for it. The authorization serial number in the software license certificate is the license key.

Obtaining a trial license key

If you need a trial license key to verify the functionality of a feature before you making a purchase decision, contact your H3C sales representative or H3C Support.

Identifying the license storage on the device

To identify the free space of the license storage, access the CLI or Web interface of the device.

·     From the CLI, execute the display license feature command in any view.

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.

Figure 14 Identifying the license storage

 

·     From the Web interface, click the system view tab at the bottom of the page, select System > License Management from the left navigation pane, and then click the Compress tab to identify the license storage.

Figure 15 Identifying the license storage

 

Compressing the license storage on the device

About this task

The license storage stores licensing information and has a fixed size.

You compress the license storage to delete expired and uninstalled license information to ensure sufficient storage space before applying for an activation file.

If no license has been installed on the device, you do not need to compress the license storage.

Restrictions and guidelines

Back up the Uninstall keys for the uninstalled licenses for subsequent license transfer or license uninstallation on H3C License Management Platform.

If uninstalled licenses or expired licenses exist on the device, the compression operation will make the DID change. You will be unable to install the activation key or activation file obtained by using the old DID on the device. As a best practice, install all activation files registered with the old DID before performing a compression.

If you have not installed an activation file registered with the old DID, take the following actions:

·     If the license storage is sufficient, install the activation file on the device. For more information, see "Installing an activation file on the device."

·     If the license storage is insufficient and the activation file cannot be installed after the compression, contact H3C Support.

Procedure (from the CLI)

1.     Execute the system-view command to enter system view.

2.     Execute the license compress command to compress the license storage.

Procedure (from the Web interface)

1.     Click the system view tab at the bottom of the page.

2.     From the left navigation pane, select System > License Management, click the Compress tab, click Compress, and then click OK in the dialog box that opens.

Figure 16 Compressing the license storage

 

Obtaining device information from the device

Device information is required for license registration on H3C License Management Platform.

CLI

Log in to the CLI of a device and obtain the following parameters:

·     H3C device SNYou can execute the display device serial-number command in any view to obtain the value of the SN field.

·     DID or DID fileYou can execute the display license device-id command in any view to obtain the value of the Device ID field. Use FTP or TFTP to upload the DID file to the PC. If FTP is used to transfer the DID file, use the Binary mode.

Figure 17 Obtaining the DID file

 

The values for the fields depend on the device model.

Web interface

1.     Click the system view tab at the bottom of the page.

2.     From the left navigation pane, select System > License Management, click the Obtain DID tab, and then click Export DID.

Appendix  A License sharing

Overview

WLAN AP license sharing technology is introduced. It allows ACs to share AP licenses with the ACs without any AP licenses installed. This technology also achieves centralized management of licenses and efficient use of license resources.

WLAN AP license sharing technology functions in different networks to implement different purposes.

·     WLAN IRF license sharing.

·     WLAN AP license synchronization between ACs.

·     License sharing in distributed unified wireless AC (UWAC) deployment.

WLAN IRF license sharing

The WLAN IRF technology virtualizes multiple physical devices into one virtual fabric. AP licenses installed on member devices are shared across the IRF fabric.

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

·     The sum of AP count allowed by all licenses on member devices.

·     The upper limit on the AP count supported by the connected device.

As shown in Figure 49, AC 1 has L1 licenses installed, allowing L1 concurrent online APs. AC 2 has L2 licenses installed, allowing L2 concurrent online APs.

·     After an IRF fabric is formed, it has a total of L1 + L2 licenses, allowing L1 + L2 concurrent online APs.

·     If a member device is faulty or leaves the IRF fabric, its licenses continue to function for a 30-day grace period in the IRF fabric to ensure service continuity.

·     After the grace period, the licenses on the leaving member device are no longer available. The license capacity reduces to the sum of the remaining licenses in the fabric. The license capacity change will not bring the existing online APs offline even if the number of existing online APs exceeds the license limit. The new limit takes effect after the number of existing online APs goes below the limit.

Figure 49 WLAN IRF license sharing

 

WLAN AP license synchronization between ACs

In this solution, each AC manages their own APs independently. You can configure the AP license synchronization feature on the ACs that can reach each other.

According to the number of ACs configured with the AP license synchronization feature, WLAN license sharing functions in the following modes: dual-AC mode and N+1 mode (N≥2).

Dual-AC mode

When two ACs are configured with the license synchronization feature, they work in the dual-AC mode. In this mode, the number of licenses is accumulated.

The maximum number of concurrent APs associated with an AC cannot exceed the following limits:

·     The sum of AP count allowed by all licenses on the two ACs.

·     The upper limit on the AP count supported by the connected AC.

As shown in Figure 50, AC 1 has L1 licenses installed, allowing L1 concurrent online APs. AC 2 has L2 licenses installed, allowing L2 concurrent online APs.

·     After configuring AP license synchronization, each AC has L1 + L2 licenses, allowing L1 + L2 concurrent online APs.

·     If an AC is faulty, its licenses continue to function for a 30-day grace period to ensure service continuity.

·     After the grace period, the licenses on the leaving AC are no longer available. The license capacity reduces to the number allowed by the licenses on the remaining AC. The license capacity change will not bring the existing online APs offline even if the number of existing online APs exceeds the license limit. The new limit takes effect after the number of existing online APs goes below the limit.

Figure 50 License sharing in dual-AC mode

 

 

NOTE:

1+1 backup is a typical example of dual-AC mode. In this mode, licenses are installed on only the master AC. After configuring AP license synchronization, the master AC synchronizes its licenses to the backup AC. When the master AC fails, the backup AC will take over the service, and APs will be reassociated with the backup AC.

 

N+1 mode

When more than two ACs are configured with the license synchronization feature, they work in the N+1 (N≥2) mode.

In this mode, N master ACs are configured, and one AC acts as the backup AC. The master ACs do not share their licenses with each other. They only synchronize their licenses to the backup AC. In this case, the license capacity on the ACs varies:

·     Each master AC allows the number of APs that are licensed by its own licenses.

·     The backup AC allows the accumulated number of licensed APs allowed on all master ACs.

In addition, the maximum number of concurrent APs associated with an AC cannot exceed the upper limit supported by the AC.

When a master AC fails, the APs associated with to the AC switch to the backup AC. When the faulty AC recovers, the APs are reassociated with the recovered AC.

As shown in Figure 51, AC 1 through AC n act as master ACs, and AC n+1 acts as the backup AC. AC 1 has L1 licenses installed, allowing L1 concurrent online APs. AC n has Ln licenses installed, allowing Ln concurrent online APs. No licenses are installed on the backup AC.

·     After configuring AP license synchronization on the ACs, the license capacity on the backup AC equals the accumulated number of licenses on the master ACs. The license capacity on each master AC remains unchanged.

·     If a master AC is faulty, its licenses continue to function for a 30-day grace period to ensure service continuity. The APs associated with the AC switch to the backup AC.

·     After the grace period, the licenses on the leaving AC are no longer available. The license capacity on the backup AC reduces to the number of the licenses on the remaining master ACs. The license capacity change will not bring the existing online APs offline even if the number of existing online APs exceeds the license limit. The new limit takes effect after the number of existing online APs goes below the limit.

Figure 51 License sharing in N+1 mode

 

Distributed UWAC deployment license sharing

The unified wireless AC (UWAC) technology enables a switch to support the WLAN function through a unified wired-wireless AC feature pack installed on the switch. The unified wired-wireless AC feature pack is installed on the MPU of a modular switch or on a fixed-port switch.

Switches in distributed UWAC deployment operate in the following modes: dual-MPU mode or IRF mode. The unified wired-wireless AC feature packs are installed on both master and backup devices. All WLAN packets received by the master and backup devices are sent to the master device and only one unified AC provides WLAN access service at a time.

The license sharing in a distributed UWAC network functions similarly as the license sharing in a WLAN IRF network.

In dual-MPU mode

Typically, a high-end modular switch uses two MPUs. After installing unified wired-wireless AC feature packs on two MPUs, AC functionality is enabled and the standby MPU functions as a backup AC.

As shown in Figure 52, the master MPU has L1 licenses, allowing L1 concurrent online APs. The standby MPU has L2 licenses installed, not allowing any APs to access.

·     With license sharing enabled, each MPU has L1 + L2 licenses, but only the master MPU allows L1 + L2 concurrent online APs.

·     If the master MPU is faulty, the backup MPU takes over the services. The master MPU's licenses continue to function for a 30-day grace period to ensure service continuity.

·     After the grace period, the licenses on the leaving MPU are no longer available. The license capacity reduces to the licenses on the remaining MPU. The license capacity change will not bring the existing online APs offline even if the number of existing online APs exceeds the license limit. The new limit takes effect after the number of existing online APs goes below the limit.

Figure 52 Dual-MPU mode license sharing

 

 

NOTE:

In a live network, the standby MPU has no licenses installed, and it uses the licenses shared by the master MPU.

 

In IRF mode

As shown in Figure 53, multiple switches form an IRF fabric. The unified wired-wireless AC feature pack is installed on each IRF member device and each IRF standby device functions as a backup AC.

·     The master switch has L1 licenses installed, allowing L1 concurrent online APs. The standby switch n has Ln licenses installed, not allowing any APs to access.

·     After an IRF fabric is formed, the license capacity on each AC equals the accumulated number of licenses on all ACs, but only the master AC allows the access of APs.

·     If the master switch is faulty or leaves the IRF fabric, a standby switch becomes the master to provide AP access services. The licenses of the original master device continue to function for a 30-day grace period in the IRF fabric to ensure service continuity.

·     After the grace period, the licenses on the leaving member device are no longer available. The license capacity reduces to the sum of the remaining licenses in the fabric. The license capacity change will not bring the existing online APs offline even if the number of existing online APs exceeds the license limit. The new limit takes effect after the number of existing online APs goes below the limit.

Figure 53 IRF mode license sharing

 

 

NOTE:

In a live IRF network, standby devices typically have no licenses installed, and they use the licenses shared by the master device.

Appendix C  FAQ

License activation

Q: What is a license key and what is an activation file?

A: A license key uniquely identifies a license. An activation file uniquely binds a license key to a device. To use a license-based feature on a device, you must install the activation file for that license on the device.

·     To obtain a license key, purchase a software license certificate from an H3C approved sales channel.

·     To obtain an activation file, access H3C License Management Platform at https://new-licensing.h3c.com/website/anonymous/navIndex/en-US/activate/input-license. Then, request an activation file based on the license key and hardware information of the target device.

Q: Can I modify the system time of the device after a license is installed?

A: For a permanent license or a days-restricted license, modifying the system time does not affect the license validity period.

Q: Might the DID file for the device change? What impact does a DID file change have?

A: The DID file would change if you compress the license storage area by using the license compress command.

The DID file change does not affect the activated licenses on the device. However, you will be unable to install the activation files obtained by using the old DID on the device. To resolve the issue, contact H3C Support.

To obtain a new activation file, you must export the new DID file from the device.

Q: Do I need to purchase and install new licenses for licensed features on the device after a software upgrade?

A: No, you do not need to do this. Unexpired licenses will continue to take effect after the device software upgrades.

Q: Will activated license activation files be lost after the device reboots or the device software upgrades?

A: No, they will not.

License uninstallation

Q: Can I uninstall an expired license?

A: No, you cannot. To delete expired licenses, execute the license compress command.

Q: How do I obtain the Uninstall key for a license?

A: Execute the display license command, identify the activation key for the feature license, and examine the Uninstall Key field for its Uninstall key. The value for this field depends on the device model.

Figure 76 Sample output from the display license command

 

Q: Can I install an uninstalled activation file on the device again?

A: No. An activation file will become invalid after you uninstall it. To restore the license, use one of the following methods:

·     License transferOn H3C License Management Platform, use the Uninstall key to transfer the license to the device again and obtain a new activation file. Then, install the new activation file on the device.

·     License uninstallation and reactivationPerform the following operations:

a.     On H3C License Management Platform, use the Uninstall key to request license uninstallation, which unbinds the device and the license key.

b.     Use the license key and device information to request a new activation file.

c.     Install the new activation file on the device.

Support for license transfer and uninstallation depends on the device model. For more information, see the license matrixes document for that product..

Q: How do I delete expired and uninstalled licenses?

A: Execute the license compress command. This operation will change the DID or DID file.

As a best practice, perform the following tasks before you compress the license storage:

·     Back up the Uninstall keys of uninstalled licenses for subsequent license transfer or license uninstallation.

·     Install all idle activation files registered with the old DID.

Q: What should I do if I inadvertently delete the activation file for a license?

A: After you delete the activation file for a license, you will be unable to use the licensed feature or uninstall its license for file transfer.

To resolve the issue:

1.     Execute the copy command to copy the backup activation file to the license folder in the root directory of the storage medium on the device, for example, flash:/license.

2.     Reboot the device. Then, the licensed-feature continues to take effect and you can uninstall the license if needed.
