• How to Merge Wireshark Capture Files: A Simple Way to Combine Packet Captures
  When troubleshooting a network problem, you don't always end up with one convenient Wireshark capture file. Sometimes you have multiple packet captures taken from different interfaces, different locations, or different points in time. Instead of opening each file separately and trying to piece everything together, Wireshark can merge multiple capture files into a single file.

• Wireshark Trace File Reporting Using Excel
  If you have ever opened a large Wireshark capture file and thought, “There has to be an easier way to see what is happening here,” you are not alone. A packet capture contains an incredible amount of information, but sometimes the packet list itself makes it difficult to visualize a problem.

• Wireshark LLDP and CDP Capture: A Powerful Tool for Network Discovery and Troubleshooting
  If you're troubleshooting a network and you're not using Wireshark to look at LLDP and CDP packets, you're missing some incredibly useful information. Both Link Layer Discovery Protocol (LLDP) and Cisco Discovery Protocol (CDP) are designed to help network devices identify their neighbors, and Wireshark lets you see exactly what those devices are telling each other. Instead of relying solely on switch management interfaces or guessing which device is connected to which port, you can capture the actual discovery traffic and inspect it packet by packet.

  I would say packet slicing is one of the most critical techniques to understand. Back in the day when we had hard drives with limited disk space and we needed to capture for long periods of time, we used packet slicing.

• Filter Like a Pro: How Wireshark Display Filters Save You Hours of Headaches
   If you’ve ever opened Wireshark and stared at the endless flood of packets flying across your screen, you know it can feel like trying to find one drop of water in a waterfall. That’s where display filters come in. Learning how to use Wireshark display filters — especially for things like narrowing traffic down to a specific IP subnet — is like flipping on a spotlight in a dark room. Instead of drowning in packets, you can instantly zero in on exactly what matters.

• Passive Discovery with Wireshark: Finding Devices the Safe, Quiet Way
  Wireshark is an ideal tool for passive device discovery because it listens without touching the network — no probes, no ARP scans, no extra traffic that could disturb production systems. When you capture traffic at a mirror/span port or on an access point,  ..
