Why device classes?

Quantellium does not support classless devices. Each device belongs to a class. The main reasons for the existence of classes are simplicity, consistency and ease of use. Properties assigned to a class are automatically inherited by any device belonging to that specific class.

Quantellium provides a number of standard classes for the most common purposes (see screenshot). A standard class can be used “as is” or locally cloned and modified. You can also create and use your own class definition.

Devices can be grouped into classes based on:

  • their (specialized) role in the network infrastructure (firewall, proxy, DHCP server)
  • their function (router, switch)
  • their operating system (Windows 2008R2, Red Hat EL6)
  • their importance (core router, main power supply)
Device classes

The row numbers below correspond to the hot spot numbers on the screenshot.

  1. dcName: The Class name is a mandatory field. Only characters from the limited set are allowed. There is no restriction on the name length but for sorting purposes it should begin with a letter (a..z,A.. Z).
  2. Repos: Is it a standard Quantellium class (FineConnection repository) or is it a custom-made class that is stored in the local repository?
  3. dcBSR: Supports this device class bridging, switching or routing. Quantellium uses this setting for “Error Control” and the determination of the ranking of a device of this class.
  4. dcManInt: Quantellium supports easy access to the management interface of a device by including an option in the context menu of a device. From the Quantellium browser session, a locally installed client (mstsc, putty) is used to provide access.
  5. dcsDCs: The Manage link gives access to a page with the options to specify the available data collectors for a class.
  6. dcETAF: Take action (send a message or start a program or script) in response to an event or incident for the events indicated by the icons.

To Clone a class

As mentioned earlier, Quantellium offers a series of predefined classes out-of-the-box. The ability to adjust properties of a standard class is limited. If you want to create a new class, it is advisable to clone an existing class and then adapt it to your needs.

To Delete a class

The Actions column also contains a link to delete a class. Note that both, in use as well as standard classes, can not be removed!

To Add or Modify a class

To Add a new class, click the Add Class button at the bottom of the page OR click the Add or Modify tab in the upper-right corner (screenshot below).

Use to Modify link in the Actions column to modify an existing class.

Upload and use your own class icons

Quantellium provides a default set of class images where you can choose from when building a custom class. Of course you can also upload your own images. The standard class images are stored in the directory:


Your image must meet the following requirements:

  • It must be a * .png file with a transparent background.
  • It must have a size of exactly 48×48 pixels.
  • The name of your images must be icon_xxx_48.png. Where xxx is a non-existent file index in the stdicons directory.

Upload your image to the stdicons directory mentioned above and reload the Add or Modify a class page. Your image should now be visible in the list.
