### **🌟 Introduction**

This project demonstrates how to send and receive VLAN-tagged Ethernet frames using the W5500 Ethernet chip in **MACRAW mode**. The workflow involves:

- Sending and receiving Ethernet frames with VLAN tags.

- Analyzing network traffic with Wireshark.

- Capturing and reviewing hardware signals using an oscilloscope.

---

### **📂 Project Overview**

The project includes the following materials:

**Wireshark Capture Files**:

- `.png` files for analyzing network traffic.

- Example file: `data/vlan_test_capture.png`.

**Python Scripts**:

- Scripts for generating data frames and controlling the W5500.

- Example script: `./py/vlan.py`.

---

### **🛠️ Setup**

Follow these steps to set up the project:

**Install Python**:

- Python 3.7 or later is required.

- Install the required packages:

```plaintext
pip install pyserial scapy
```

**Install Wireshark**:

- Download and install Wireshark from the [official website](https://www.wireshark.org/).

---

### **🚀 How to UseRun the Python Script**:

- Generate VLAN-tagged frames and send them using the W5500:

```plaintext
python ./py/vlan.py
```

#### A VLAN packet Frame

#### ![](https://maker.wiznet.io/upload/ckeditor5/19234754%5F1732894933%2EPNG) **Analyze with Wireshark**:

- Open Wireshark and capture packets from your network interface.

- Apply a VLAN filter (`0x8100`) to isolate VLAN-tagged packets:

```plaintext
vlan
```
