The tool also provide two mode, which are real time mode, and simulation mode.
In the real time, students/ user can have a clear vison of how the devices behaves. In this mode, devices behave as real devices.
In the other hand, the simulation mode help students / user to understand the fundamental concept behind the network operations. This mode permit user to see and control time intervals, and to visualize the propagation of data across a network. [3]
Cisco devices configuration methods
Cisco packet tracer allow us to configure devices using two options: config tab or CLI tab (command line interface).
With command line interface, we configure devices using cisco command line. The advantage of using the command line interface is that, the commands we use to configure devices virtually are the same command we use with the real devices. [8]
The Figure 2.3 below represents a router configuration using a Command line interface (CLI).
The config tab did not required any cisco commands knowledge. Configuration with config tab is done through a graphical interface. This configuration method can be use in the situation where user does not have enough time and want to configure devices quickly. This technique can help us saving time during configuration. [8]
The Figure 2.4 represent a router configuration with Config Tab.
