Network Layer - Takes care of finding the best (and quickest) way to send the data.Data Link Layer- Makes sure the data is error-free.Physical Layer - Responsible for the actual physical connection between devices.The OSI Model segments network architecture into 7 layers: Application, Presentation, Session, Transport, Network, Datalink, and Physical. The Open Systems Interconnection (OSI) model standardizes the way two or more devices connect with each other. This is important to understand the core functions of Wireshark. I am assuming you are new to networking, so we will go through some basics of the OSI model. While most security tools are CLI based, Wireshark comes with a fantastic user interface. Wireshark is also completely open-source, thanks to the community of network engineers around the world. Most enterprises and government organizations now prefer Wireshark as their standard network analyzer. It can run on all major operating systems. Wireshark was first released in 1998 (and was called Ethereal back then). It lets you dissect your network packets at a microscopic level, giving you in-depth information on individual packets. Wireshark is a network analyzer that lets you see what’s happening on your network. In this article, we will look at it in detail. ‘Play’ button at the lower right side in the Main tab to initiate the programming.Wireshark is the best network traffic analyzer and packet sniffer around. Make sure that Erase, Program and Verify are checked. Images are located with the SimpleLink CC13x0 SDK installation in the folderĬ:\ti\simplelink_cc13x0_sdk_1_30_00_xx\tools\ti154stack\TiWsPc2\sniffer_fw\bin. Your TI 15.4-Stack configuration (See Table 19.). In the Main tab browse to the correct sniffer firmware image depending on Select the CC1350/CC1310 device in the list of connected devices at left side. Perform the following steps to program the Launchpad board with sniffer firmware:Ĭonnect the Launchpad board to the PC with a USB cable. The firmware can be programmed with SmartRF Flash Programmer 2. The firmware image to use depends on the frequency band and TI-Stack PHY mode.
The Launchpad board must be programmed with the correct firmware before it can be used as packet sniffer.
