Application settings

The Fabric Service System's Settings page provides access to several configuration settings that affect the way the system behaves.

  • the Image Management and Software Catalog panels pertain to the SR Linux software images available on the Fabric Services System's file server.
  • the Global Configuration panel manages FTP and NTP settings on the SR Linux nodes configured by the system.
  • the Common Application Settings page determines the background map image used with specific views, and whether you are using Kibana and Elasticsearch to view log data generated by the system's internal microservices.

Software and image catalogs

The Fabric Services System maintains a catalog of software images which are used to configure nodes within managed fabrics.

The software images in the catalog are used when:

  • creating a fabric intent; you must select one version of the SR Linux software which is deployed to all nodes participating in the fabric as part of their configuration. See Fabric intents.
  • creating a maintenance intent for changes to a node's software version; you must select one version of the SR Linux software from the catalog which is deployed to all nodes that are subjects of the maintenance intent. See Maintenance intents.

To view the system's current software catalog:

  1. Click to open the main menu.
  2. Select Settings. The Settings page displays.
  3. Click Software Catalog. The current software catalog displays, identifying for each entry:
    • the Vendor: currently only Nokia is supported.
    • the Operating System: currently only SR Linux is supported.
    • the Software Version: the system is pre-loaded with selected versions of the SR Linux software image, and this list grows as you load additional versions over time.

Adding a new software image

  1. Click to open the main menu.
  2. Select Settings.The Settings page displays.
  3. Click Image Management. The current image catalog displays.
  4. Click +ADD IMAGE. The Image Details dialog displays.
  5. Enter information for the new software image:
    • the Image URL: a location from which the system can download the image file to the file server.
    • the MD5 URL: a location (on the same file server as the Image URL) from which the system can download the MD5 file to the file server.
    • a Username and Password: credentials required to download files from the Image URL.
    • Optionally, a Description for this software image.
  6. Click SAVE.
    The system adds the image to the image catalog and downloads the specified image from the source you provided to its integrated file server.

    In addition to the information you provided in step 5, the image catalog displays for each software image:

    • Image Name: the name of the image file on the file server.
    • MD5: either True or False, indicating whether the MD5 file has been successfully added.
    • Upload Status: the image status, which can be any of the following:
      • Done
      • Failed
      • Adding
      • Overwriting
    • Path: for a successfully obtained image, the path to the image and MD5 files on the integrated file sever.

Global configuration settings

Global configuration settings represent data that the Fabric Services System incorporates into the configuration files of any node included within a fabric intent.

FTP

The FTP toggle enables or disables the use of File Transfer Protocol (FTP) by the nodes configured by the Fabric Services System.

The UI supports two settings for FTP:

  • Enabled (toggle ON): nodes configured by the Fabric Services System include a setting to enable FTP on the node.
  • Disabled (toggle OFF): nodes configured by the Fabric Services System include a setting to disable FTP on the node.

To configure the FTP setting:

  1. Click to open the main menu.
  2. Select Settings .
  3. Click Global Configuration.
  4. Set the Enable FTP toggle to either disabled (left, gray) or enabled (right, blue).
  5. Click the SAVE button at the lower right of the page.

NTP

The NTP setting specifies one or more Network Time Protocol (NTP) servers; this information is incorporated into the configuration file for all nodes configured by the Fabric Services System.

Adding one or more NTP server IP addresses enables the system NTP client on the node, and is used for system clock synchronization.

To add an NTP server that is included in node configurations going forward:

  1. Click to open the main menu.
  2. Select Settings .
  3. Click Global Configuration.
  4. Click + ADD.
  5. Enter the IP address of an NTP server.
    This should be an ipv4 address with an optional CIDR.
  6. Click the ADD button.
  7. Repeat steps 4 through 6 until you have added all the required NTP server addresses.
  8. Click the SAVE button at the lower right of the page.

Common application settings

The Common Application Settings panel determines the background map image used with certain views.

Geomap

The background image displayed for the region map is determined by the system's Geomap Tile Server setting.

To assign or change the background map:

  1. Click to open the main menu.
  2. Select Settings.
  3. Click Common Application Settings.
  4. In the Geomap panel, enter:
    1. Tile Server: enter a URL that points to a specific tile server and an image on that server to function as the background for the region map
    2. Attribution: enter an attribution for the background image.
      The attribution field is mandatory.
  5. Click the SAVE button at the lower right of the page.
The selected image displays the next time you open the region map.
