Read this section carefully before you configure a license.
The automatic online activation and license trial functions can be configured only on the web UI.
In hot standby scenarios, you need to apply for license files for the active and standby devices and load the obtained license files to the two devices respectively.
In hot standby scenarios, information, such as license control item types, resource quantities, expiration dates of intrusion prevention, antivirus, and URL remote query update services and license statuses on the active and standby firewalls must be consistent.
If active/standby switchover occurs, hot standby services may be affected. For example, if the number of licensed resources on the active firewall is greater than that on the standby firewall, service resource usage might be affected after active/standby switchover. To prevent such conditions, ensure that the license control items and license status on the active and standby firewalls are consistent in hot standby scenarios.
After the license file expires(use the expiration time of the latest control item), there is a 60-day grace period. After the grace period expires, the license file immediately becomes invalid. After the license file enters the grace period, the system sends a FWLCNS_1.3.6.1.4.1.2011.6.122.16.5.7 hwLicenseFileExpired alarm every day to notify you that your license file has expired and how many days are left before the grace period expires. If some license control items have expired, the system sends a FWLCNS_1.3.6.1.4.1.2011.6.122.16.5.9 hwLicenseFeatureExpired alarm.
