1 Create the topology 

Add devices to topology area and connect them to eachother. In this task we need four layer 2 switches (e.g. Cisco 2950) and six hosts (PCs). 

To add switches to your topology area simply go to Network devices -> Switches and choose a 2950 switch.

To connect switches to eachother, you need to use Cross-Over cable. To do so, go to “Connections” category, select “Copper Cross-Over” connection and choose the interfaces that you want to connect on each switch.

Another option is to choose the first option from the left, “Automatically choose connection type”. In this case the appropriate cable and interface will be selected each time you decide to connect devices together.

Last but not least you need to connect PCs to switches. To do so, Copper Straight-Through cable needs to be used.

2 Determine IP addresses and subnet masks to be used 

Before configuring your devices with IP/Mask, you need to define your scope of IP addresses.

**It is recommended to write the Network ID/mask of each device/interface next to it, so you can keep track of all the IP addresses used in your scenario. To do so:

- Click on the “Place Note” icon (second icon from the top) in the right toolbar. Then click on the topology area and type the IP address/mask or any information that you need to add to your scenario.

* If you cannot see the right pane, go to View -> Toolbars and tick the “Right Toolbar”.

As it is shown in the figure, the IP/Mask that is used in this example is:

3 Assign IP addresses

To assign IP addresses to PCs:

Click on the intended PC -> IP Configuration -> Desktop tab

You need to repeat this for other 5 hosts as well.

4 Configure administrative settings

These settings include setting name, password, banners and interface descriptions

The following figures show required commands for each administrative setting as well as the correct mode that these commands should be issued.
