Catalyst 9000 series Switch License.

This time, the communication related to the license authorize was blocked due to the firmware problem of the C9200L device, so the problem was solved through manual license key registration.
Reference Manual:

Through the above manual, all of the C9200L equipments that had problems seemed to be okay temporarily.
But for some reason, some devices again caused licensing problems.
Both cases of the equipment that were normal and the equipment that took the above measures were changed to trial mode.
When I logged in to and checked the SA, the last communication was about 2 weeks ago for the device with the problem, but the evaluation version of the device was about 30 days away.

Question 1. If the trial mode expires, is there any problem with the network function?
Question 2. Is there only OS upgrade to solve the above problem?

 - I would phrase that other wise and revert , the OS upgrade (resolved versions)  as mentioned in the field notice is the strongest advisory method to resolve these issues.
