Updating the Artificial Intelligence Engine Database Using the CLI

Before updating the artificial intelligence engine database, do as follows:

• Checking the License Status

  Before updating the artificial intelligence engine database, ensure that the artificial intelligence engine license has been purchased and activated.

  To check the license status, perform the following operation:

  1. Run the display license command to check whether the required license has been activated or has expired.

     • If the status is Disabled, activate the license. For details on how to activate the license, see License Management.

     • If the status is Enabled, check whether the license has expired. If yes, purchase the license.

• Checking the Free Space of the CF Card and Memory

  Before updating the artificial intelligence engine database, check whether the free space in the device CF card and memory is sufficient. The following table lists the CF card and memory space required for updating the artificial intelligence engine database.

  Item	CF Card Space	Memory Space
  artificial intelligence engine database	100 MB or higher	50 MB or higher

  Perform the following operation:

  1. In the user view, run the dir command to check the free space of CF card.

     <sysname> dir
     Directory of hda1:/                                                             
                                                                                     
       Idx  Attr     Size(Byte)  Date        Time       FileName

     1,200,576 KB total (379,168 KB free)                              

  2. In the user view, run the delete command to delete unwanted files from the CF card if the free space is insufficient.

     

     Files are deleted and cannot be restored after the delete command with the /unreserved parameter is executed.

• Checking the Current Update Status

  You can update artificial intelligence engine database only after the current update status is idle.

  To check the current update status, perform the following operation:

  1. Run the display update status command to check the update status.

     <sysname> display update status
       Current Update Status: Idle.
     

     If Current Update Status is Idle, you can update the AI Engine. Otherwise, repeat the display update status command until Current Update Status changes to Idle, and then update the AI Engine.

• Checking the artificial intelligence engine database Version

  Check the artificial intelligence engine database version to determine whether the AI Engine needs to be updated.

  Details are as follows:

  1. Run the display version aie-sdb command to check the artificial intelligence engine database.

     <sysname> display version aie-sdb

     ------------------------------------------------------------------------------

The artificial intelligence engine database can be updated in either of the following modes:

• Online update

  If the FW can communicate with the update center directly over the Internet or through a proxy server, you can update the artificial intelligence engine database in online mode.

• Local update

  When the FW is physically isolated from the Internet and no proxy server is deployed on the intranet, you can update artificial intelligence engine database locally.

The FW is deployed at the border of the internal network as the security gateway. The FW can communicate with sec.huawei.com through the Internet. Through immediate update or scheduled update, the FW can automatically download the artificial intelligence engine database and update the local artificial intelligence engine database.

Figure 1 Networking diagram for online update

The update package has been uploaded to the memory of the FW using SFTP, FTP or TFTP.
