Once a topology has been created, connectivity can be tested between devices by using either simple or complex PDUs. Although it is possible to do the same by pinging devices from their command-line interface, using the PDU option is quicker for large topologies.
The Add Simple PDU option uses only ICMP (Internet Control Message Protocol). We will create a topology with a PC and a server to demonstrate how this option works:
Add a PC and a server to the workspace and connect them using a copper crossover cable.
Assign IP addresses to both of them in the same subnet. Example, PC1:
192.168.0.1/255.255.255.0and PC2:192.168.0.2/255.255.255.0.From the common tools bar, click on the closed envelope icon or use the shortcut key P.
The pointer will change to an envelope symbol. Click on the PC first and then on the server. Now look at the User Created Packet box. You'll see the status as Successful and will also see the source, the destination, and the type...
