Other: Why Is a License in Trial State? What Should I Do?

Run the display license file-name and display esn commands in any view to check whether the ESN in the license file is the same as the actual ESN of the device.
1. If the ESNs are different, use the ESN of the device to apply for a new license file, upload the new license file to the device, and activate the license file.
2. If the ESNs are the same, go to step 2.
Check whether the license file contains a license revocation code (indicated by Revoke ticket). If you have run the license revoke command, the license file enters the Trial state.
1. If a revocation code is found in the license file, apply for a new license file based on this revocation code, upload the new license file to the device, and activate the license file.
2. If no revocation code is found in the license file, go to step 3.
Check whether the license file is a temporary license (whose Authorize type is demo) and whether its validity period has elapsed. If a temporary license file expires, it enters the Trial state.
1. If so, use the ESN of the device to apply for a commercial license, upload the license file to the device, and activate the license file.
2. If not, go to step 4.
If the license file still cannot restore to the Normal state, contact technical support personnel.
