  - **Ethernet**: The captured data is from the wired network packets.
  - **WLAN**: The captured data is from the wireless network packets.
- **PCAP Specific Port**: Select the specific port from 1-65535 so that only the data packet from the specific port can be captured. You can leave the field blank by default.
