Cisco CCNA Network Simulator is a boxed software product derived from the previously self-published Boson NetSim from Boson Software. It provides users with a means to develop hands-on skills at the CCNA level without the investment in expensive hardware. The software, which includes the Boson Router Simulator, was designed to give users the skills needed to pass the new CCNA 800 series exams (640-801, 640-811, and 640-821). The combination of Cisco IOS and Catalyst simulated command line interface (CLI) establishes a foundation of knowledge that is integral to CCNA success, both in taking the CCNA exams and in their daily job as a CCNA professional. The title includes a drag-and-drop Network Designer that supports up to 200 devices using 45 different device models, including 40 different router models and 2 Catalyst switch models. Users can have up to 200 active telnet sessions configuring devices inside the simulator. Currently no other network simulation packages offer this much versatility and support. This unique feature allows users to create their own lab topologies, freeing them for the first time from the configurations locked in place by the software vendor. Cisco CCNA Network Simulator also includes a comprehensive lab menu that contains more than 100 structured labs for users to run. More than 20 advanced-level labs from Wendell Odom's CCNA texts allow users to perform complex tasks on networks that combine all the various CCNA technologies.
