License: A license is an agreement that the supplier and customer arrive at and authorizes the range and period of using the purchased product (it refers to the software product in this document). Through the license, the customer also obtains the services committed by the supplier. A license contains a license file and a license authorization certificate.
After purchasing a product, you can only use basic functions of the product. To use value-added service features or expand device resources, purchase licenses of corresponding device functions or resources to meet service requirements.
The license reduces costs for you. You can select the licenses to obtain customized functions.
Depending on purpose, licenses are classified into commercial (COMM) licenses and non-commercial (DEMO) licenses.
Typically, most licenses purchased according to contracts are permanently valid and some with a fixed validity period. All purchased licenses are COMM licenses.
The temporary license is also known as a DEMO license, which is used for special purposes such as test and trial, and are strictly controlled.
Depending on authority, licenses are classified into function licenses and resource licenses:
A function license controls the usage of a specific function. To use a restricted function, obtain authorization for this function first.
A resource license controls the number of available resource items. To use a resource item, obtain authorization for this resource item first.
You may not select a resource license as the default license is sufficient for your resources. You can also select one or more resource licenses based on actual service needs. You can select multiple types of resource licenses. The resource quantity is the sum of all resources in all selected resource licenses.
The resource capacity allowed by the licenses you purchased cannot exceed the maximum capacity of the product. To learn the maximum capacity of the product, contact Huawei local office.
Installing a license file on a device does not require a device reboot and will not affect running services.
Traditional license mechanism binds license files to Equipment Serial Numbers (ESNs). That is, a license file belongs to only one device. If a license file is modified manually, the file becomes invalid. This protects the license against theft.
If an accident such as an earthquake happens and rescue is organized, you can set the status of the license activated by traditional license mechanism to Emergency. In this status, the resource license does not limit resource usage. The device provides maximum number of resources to meet service requirements. The Emergency state can only be used certain times within the specified period. For details, see Other: How Do I Enable Emergency State of a License?.
Only one license file can be loaded on a device. If features or resources provided by a license file are insufficient, you can expand the license capacity to expand features or resources available on a device. The ESDP automatically sums up all the license items on a device to generate the total capacity license file, which simply needs to be re-loaded for use.
Only a commercial license requires a license certificate.
