A license is an agreement in which the supplier authorizes a customer to use certain functions of the purchased products within a validity period. The physical form of a license is a license file, also called Global Trotter License (GTL). NetEngine 8000 F software is subject to a license, which specifies features, versions, capacities, and expiration for the product. Through the license, a customer obtains the services committed by the supplier. A license grants a customer the right to use software but not ownership of software.
A license file is an authorization file that controls the capacity and functions of a product. This file is generated on the Electronic Software Delivery Platform (ESDP) website (https://app.huawei.com/sdp/) based on the project contract and device information. In most cases, a license file is preinstalled on a device before device shipment. Alternatively, Huawei technical support engineers can download the license file from the ESDP website based on the project contract and the device's electronic serial number (ESN).
A license file is encrypted using the device's sequence number as the key. A license can be obtained from the license management server.
