Testing connectivity with PDUs

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.

Simple PDU

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:

  1. Add a PC and a server to the workspace and connect them using a copper crossover cable.
  2. Assign IP addresses to both of them in the same subnet. Example, PC1: 192.168.0.1/255.255.255.0 and PC2: 192.168.0.2/255.255.255.0.
  3. From the common tools bar, click on the closed envelope icon or use the shortcut key P.
  4. 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 of packet that was sent.

That was very simple, wasn't it? Now let's see what complex PDUs have to offer.

Complex PDU

We will demonstrate complex PDUs with the same PC-Server topology:

  1. Click on the open envelope icon or press C; this is the Add Complex PDU option.
  2. Click on the PC and the Create Complex PDU dialog box opens. Select the application and fill the Destination IP address (IP of the server), Starting Source Port, and Time fields, and then click on the Create PDU button.

  3. Now click on the server and then look at the user-created packet box. An entry indicates a successful TCP three-way handshake as shown in the following screenshot::

See the red button under the Fire column? Double clicking on it will send the same packet again.
