(Optional) Updating the Artificial Intelligence Engine Database

Preparation

Before updating the AIE database, do as follows:

• Checking the License Status

  Before updating the AIE database, ensure that the AIE 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 so, purchase the license.

• Checking the Free Space of the CF Card and Memory

  Before updating the AIE 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 AIE database.

  Item	CF Card Space	Memory Space
  AIE 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

                                    ........

        49  -rw-          1,063  Feb 06 2015 09:13:26   nlog.log

     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 AIE 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 AIE Version

  Check the AIE database version to determine whether the AIE needs to be updated.

  Details are as follows:

  1. Run the display version aie-sdb command to check the AIE database.

     <sysname> display version aie-sdb

The AIE 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 AIE database in online mode.

  You can perform online update in either of the following modes:

  • Scheduled update

    The FW accesses the update center on a scheduled basis to check for the latest AIE database version. If the latest version is found, the FW automatically downloads the latest version and updates the local AIE database at scheduled time.

  • Immediate update

    When a new AIE database is available on the network but the scheduled update time is not reached or scheduled update is disabled on the FW, you can use the immediate update function.

    The AIE database download addresses for immediate update and scheduled update are the same, and the update processes in both modes are the same. The only difference is the update time. The immediate update can be implemented at any time.

• Local update

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

For details about how to upgrade the AIE database through the CLI in different scenarios, see Updating the Artificial Intelligence Engine Database.
