dir
The suffix of the license file is *.dat. The license file must be saved in the root directory of the storage device. You can rename the license file but cannot change the file name extension .dat. Otherwise, the system cannot upload the license file properly.
The system can have only one activated license file. Activating a new license file deactivates the original one.
The license file is stored on the CF card of the device. After being activated, the license file cannot be manually deleted from the CF card during the device operating. If the CF card is damaged after the license file is activated or the license file is deleted mistakenly from the BootROM, the license file can still be used if the device is not restarted. If the device restarts, the license file is lost on the AntiDDoS, interrupting services. In this case, you should to re-upload the license file to the CF card and activate it.
After the license file is activated on the AntiDDoS8000, you need also to run the save command to save the currently activated license file. During the next startup, the AntiDDoS automatically activates the license file activated last time to ensure that the licenses files before and after the restart are the same.
After activating the license file, run the display license command to check license information.
