Modifying an MQTT broker profile

You can change the name and settings of an MQTT broker profile.

To change the name of an MQTT broker profile:

1. In the menu in the left part of the web interface page, select the MQTT broker section.

   The Profiles table is displayed.

2. In the Name column, click the name of the profile that you want to edit.

   The Edit MQTT broker profile pane opens on the right.

3. In the Name field, enter a new profile name.
4. Click Save in the lower part of the page to save the changes.

The modified MQTT broker profile will appear in the Profiles table.

To change the settings of the MQTT broker profile:

1. In the menu in the left part of the web interface page, select the MQTT broker section.
2. In the Profiles table, in the Name column, click the  icon next to the profile that you want to change.

   This opens the Profile settings table containing a list of configuration files and certificates that are part of the MQTT broker profile. If the profile was created based on the None template, the list of files will be empty. An empty profile must be completed.

3. If you need to add a prepared configuration file to the profile, click the Upload button in the lower part of the page. In the opened file upload window, select a file in CONF format.

   The configuration file will be uploaded to the system and will appear in the MQTT broker profile settings.

   Kaspersky IoT Secure Gateway 1000 does not let you upload the main configuration file. This type of file can only be created.

4. If you need to edit a configuration file in the MQTT broker profile, click the name of the configuration file that you want to edit and do the following in the Edit MQTT broker configuration file pane that opens on the right:
   1. Click the  icon in the lower part of the pane.
   2. In the opened text editor window, change the settings as required.

      For detailed information on the settings of the Eclipse Mosquitto configuration file, please refer to the documentation on the developer's website. There are limitations when configuring the MQTT broker profile for Kaspersky IoT Secure Gateway 1000.

   3. Click Save in the lower part of the page to save the changes.

      The selected configuration file will be changed. The text editor window closes.

5. If you need to delete a configuration file from the MQTT broker profile, click the name of the configuration file and click the  icon located in the lower part of the Edit MQTT broker configuration file pane that opens on the right. Confirm file deletion.

   The selected configuration file will be deleted from the MQTT broker profile settings.

6. If you are planning to use an MQTT broker profile to connect to devices or cloud services in an external network, upload the Certification Authority certificate, client certificate, and private key. To do so, click the Upload button in the lower part of the page. In the opened file upload window, select the relevant files. Repeat this step as many times as required to upload all necessary certificates and keys to the system. In Kaspersky IoT Secure Gateway 1000, you can only upload certificates in PEM format with the CRT extension, and keys in PEM format with the KEY extension. The size of each file must not exceed 131 KB.

   The uploaded files are displayed in the profile settings.

7. If you need to remove a certificate or key from the profile, click the name of this certificate or key in the Profile settings table and click the  icon in the pane that opens on the right. Confirm removal of the certificate or key.

   The selected file will be removed from the MQTT broker profile settings.
