# 2.0.3 Packet Tracer - Examine Packets in the Small Office

## Objectives

- Part 1: Create a Simple PDU in Simulation Mode
- Part 2: View Contents of PDUs
- Part 3: Create a Complex PDU in Simulation Mode

## Background / Scenario

In this Packet Tracer activity, you will use the Simulation mode to create PDUs to explore network functionality.

> **Note:** Simulation mode does not work in Physical mode; therefore, Physical mode is locked.

## Procedure

### Part 1: Create a Simple PDU in Simulation Mode

- Step 1: Enter the Office network;

- Step 2: Enter Simulation mode;

- Step 3: Create a simple PDU that sends a ping from Office-Admin to Printer0;

- Step 4: Observe traffic moving through the network.

  1. PDU goes outbound from the Office-Admin PC to the Office-SW1 switch;

  2. Office-SW1 sends a multicast packet to find and get a response from Printer0;

  3. Printer0 replies with a response to Office-SW1

  4. Office-Admin recieves response from Printer0 forwarded by Office-SW1

### Part 2: View Contents of PDUs

- Step 1: Use the event list to see PDU information;

- Step 2: Delete the simple PDU.

### Part 3: Create a Complex PDU in Simulation Mode

- Step 1: Add a complex PDU to send pings from the PC to the laptop;

- Step 2: Configure complex PDU settings to send the pings every 5 seconds;

- Step 3: Observe traffic moving through the network.
