Capturing Traffic Using SDM UI#

This guide explains how to capture network traffic using the Simplicity Device Manager (SDM) user interface (UI) with Wireshark.

Prerequisites#

Before starting, make sure that:

  • The SDM server is running.

  • Wireshark is properly set up with SDM. For more information, see the Getting Started guide.

Capturing from a Single Adapter#

Step 1. View Available Adapters#
