Customizable Interface

Rearranging and organizing your NetSim experience is easy with our Window Docking feature. The dockable user interface allows you to rearrange and organize your display the way you want. The entire application is customizable.
You can undock anything and everything. Want to move the lab tree to the right or auto hide it? That’s easy—each tool window ("pane") may be closed, auto hidden or undocked. Plus, each console window can be dragged out of the application and relocated across multiple computer monitors.

Network Designer™

The Network Designer menu enables you to create a new topology and modify existing ones. You can add devices and connections to the topology, and you can also click and drag the devices to rearrange your simulated network.
In NetSim, the Network Designer is intuitive and robust.
With NetSim you can:
  • annotate topologies with notes and labels.
  • align elements exactly with drag snapping.
  • connect in fewer clicks with new tool types focused on specific activities.
  • configure Frame Relay easier with a new simple port-to-DLCI mapping interface.
  • locate active connections and devices easier with two new support panes.

NetSim Community Sharing

NetSim Community is a feature that allows you to easily share your own labs, lab packs and topologies directly in the application. Once your creations are approved, they will be available in the NetSim Community for other NetSim users to download.
You can also search, sort or filter the NetSim Community to look for shared content that you find helpful.

Lab History allows you to easily identify where you left off or labs that you may want to revisit. Progress icons show the status of the labs that you’ve started, completed successfully or failed.
The Lab Tree will indicate the “best” result, and the history section in Lab Preview will display your complete history.
