license revoke
Usage Guidelines
Usage Scenario
License is an authorization file. You can apply for, upgrade, or activate the license file to get corresponding user rights.
If new devices are deployed, you can purchase new licenses as needed to enable license-controlled features and functions on the devices. This reduces purchase costs. If the capacities of the existing devices need to be expanded, you can update the licenses used on the devices to enable more license-controlled features and functions.
You can upgrade a license file to:
- Add new features.
- Optimizes device performance or functions.
- Fix bugs in the current version.
Before updating a license file, run the license revoke command to revoke the existing license. The system then returns a license revocation code. This code is an evidence for license invalidation and is used to apply for a new license.
A license revocation code is a character string generated after a license file becomes invalid. You can check the revocation code to determine whether the unique license file becomes invalid.
Precautions
When the existing license is going to expire, apply for a new license, upgrade, and activate the license. If the license has expired, the service modules are disabled and services are interrupted.
After you run the license revoke command, the license file enters the Trial state and cannot be reactivated regardless of how long the file expires.
- This command cannot be executed if the ESN in the license file is different from the device ESN. Re-apply for the license based on the device ESN and activate the license on the device.
