certexams-logo-small CCNA Network Simulator has been updated to include Graphical User Interface (GUI). Conventionally, a network administrator needs to configure a router or a switch using CLI (Command Line Interface), with the exception of some Wi-Fi routers that allowed GUI configuration. Cisco, as part of its product enhancements, has been working on improving the user interface, and have come up with Cisco Configuration Professional, a GUI tool that allows network administrators to configure and troubleshoot Cisco network devices using a visual GUI interface. Certexams has introduced a limited version of the GUI based Network Configurator that allows users to do mundane tasks such as assigning IP addressses and subnet masks,  setting up DHCP, assigning host name, etc. The GUI is intended to provide some hands-on experience of working with CCP (Cisco Configuration Professional) and simulates the CCP navigation.



A typical screenshot of the feature may be seen the figure. As seen in the figure, the GUI consists of a left pane that outlines the configuration tasks, and when selected, the right pane provides the work area, where the user may select or type-in appropriate configuration. Several labs have been given to familiarize the user to configuring the network using GUI. However, this being the first release, more enhancements may be expected to Network Configurator. More configuration tasks, as well as new labs will be added in due course of time.

Other important features of the netsim software are:

  • The software is completely stand alone, and there is no need for any other software.
  • Hundreds of lab exercises to get familiarized with concepts of routing, NAT, Access lists, subnet masking, etc.
  • Configure and troubleshoot VLANs, VTP, and other switch related tasks
  • There is no hardware required, it s completely software based too.
