• M - Toggle offline device visibility
  • Normally, offline devices are shown as grayed-out icons. This can be toggled to where offline devices are hidden instead.
• B - Toggle background image
  • The map of the Continental US can be toggled off and on.
• S - Toggle sprite layer
  • The sprite layer (with injected sprites) can be toggled on and off.
• X - Lock / unlock node positions
  • The default is to allow click-and-drag to move nodes (devices & hosts) on the display. 
• Z - Toggle oblique view (Experimental)
  • This mode will show a "sideways" view of the network, separating packet-layer nodes from optical-layer nodes.
  • As noted, this mode is currently experimental.
    
    

Custom Sprites

The Topology Sprite Layer mechanism allows custom "background" elements to be displayed (above the background map, but below the topology elements). This could be used, for example, to inject labeled "subnet clouds", or the plan of an office building or campus into the topology view. Typically, one would want to hide the background map layer (press 'B') and show the sprite layer (press 'S') instead.

In the current release (1.3.0 "Cardinal") sprite layers are defined in an external JSON format and uploaded to the controller via a REST command. They are loaded into the Topology view by manually adjusting the browser URL to include a "sprites" query parameter. We hope to provide a more user-friendly mechanism (directly through the GUI) in some future release.
