Post Views: 18 The Cisco Discovery Protocol (CDP) Wireshark Profile is designed to make CDP traffic faster and easier to analyze. Rather than manually building filters and columns each time you open a capture, this profile provides a ready-to-use workspace focused on Cisco device discovery, neighbor identification, interface information, platform details, software versions, device capabilities, […]

Post Views: 84 This is our OSPF Profile for Wireshark. If you work with OSPF and you do packet capture for troubleshooting, you need this profile. See OSPF Clearly This OSPF Wireshark Profile transforms a busy packet capture into a focused routing-analysis workspace. With purpose-built filters, columns, and views for Hello packets, neighbor formation, DR/BDR

Post Views: 414 LLDP (Link Layer Discovery Protocol) is a vendor-neutral Layer 2 protocol defined by the IEEE 802.1AB that allows network devices to advertise identity and capabilities to directly connected neighbors on the same Ethernet segment. Think of LLDP as a “hello, here’s who I am and what I can do” broadcast at Layer

Post Views: 426 CAN bus (Controller Area Network) is a robust, multi-master, message-based serial communication protocol used primarily in vehicles and industrial systems to allow Electronic Control Units (ECUs) to communicate over a shared two-wire differential bus without a central host. It was developed by Robert Bosch GmbH in the 1980s for automotive applications and

Post Views: 5,590 Special thanks to Peter Gaudiomonte for sharing this profile to the repository. What is JA4+? JA4+ is an extension of the JA4 (Just Another 4-tuple) family of fingerprinting techniques. It’s used for network traffic fingerprinting—especially in encrypted traffic analysis—and can be useful for threat detection, TLS/QUIC fingerprinting, and application identification, even when

Post Views: 12,839 Now that we have the IETF QUIC and HTTP3 released and in play in the network, if you want to see this protocol, use this profile. Read more at my article here. This profile will help you work with IETF QUIC that has not been decrypted so you cannot see the HTTP3

Post Views: 1,566 This is a new version of our HTTP Profile for Wireshark. Wireshark defaults to this header reassembly process being ON. I have added a different version of this profile with this setting turned off – FYI. Header reassembly in HTTP troubleshooting can be confusing due to a combination of protocol layering, packet

Post Views: 1,822 This is a new version of our HTTP Profile for Wireshark. Wireshark defaults to a header reassembly process. I have added this version of the profile with this header reassembly setting turned off. Everything else is the same between the two profiles. Header reassembly in HTTP troubleshooting can be confusing due to

Post Views: 94,775 For those of you who love Wireshark and are supporting IPv6, we would like to offer an alternative to our default profile for IPv6. This one I call my IPv6 Super Profile. I created this based on modifying the Default IPv6 profile for a client that they called “super”. Think of it

Post Views: 6,291 Here is a UDP specific profile for Wireshark. Don’t be one of the people who overlook UDP in their troubleshooting! So many critical events in network operations actually use UDP! Especially today, with the rapid emergence of QUIC essentially replacing TCP. Enjoy. Many people overlook the UDP (User Datagram Protocol) in troubleshooting
Post Views: 113,741 TCP Delta Time refers to the time difference between consecutive Transmission Control Protocol (TCP) packets in a data transmission. It is an important metric when analyzing network performance for several reasons: 1. Network Latency and Performance High Delta Times: When the delta time between TCP packets is high, it may indicate network

Post Views: 92,092 TCP Sequence analysis is critical in network troubleshooting because it provides insights into the flow and order of data being transmitted over a network. Here’s why it plays such a crucial role in diagnosing network issues: 1. Ensuring Data Integrity and Order TCP Sequence Numbers: TCP assigns sequence numbers to each byte

Post Views: 1,227 This is a Wireshark profile that helps analyze IEC 60870 packets. IEC 60870 part 5 is one of the IEC 60870 set of standards which define systems used for telecontrol (supervisory control and data acquisition) in electrical engineering and power system automation applications. Part 5 provides a communication profile for sending basic
