Who should attend this Wireshark course
Systems support staff wanting to monitor and analyse modern telecommunications and networking protocols.
All Network and Telecommunications support staff, regardless of the types of networks they support.
All staff needing to learn the insider tips, tricks and techniques that unleash the power of Wireshark.
Wireshark Course Pre-requisites
This abridged one-day course does not allow time to give in-depth working explanations of the protocols being analysed. For this reason:
Delegates must have a good working knowledge of IP, TCP, UDP, DNS, DHCP, Ethernet and 802.1q VLANs.
See course 313: IPv4: Protocols, Implementation, Analysis, Troubleshooting and Support
The course incorporates focussed hands-on practical labs that give all student access to active networks and target systems to teach advanced hands-on practical skills.
Lifetime Post-Course Support
After completing this
Wireshark training course, delegates receive lifetime post-training support from LEVER Technology Group PLC, to help them apply the technologies and skills they have learned with us, to provide career-long support, and to ensure they are better equipped for their future roles in IT and networking.

Section 4 - Advanced Capture and Analysis of Commonly used Network and Application Protocols
This section gives a theoretical description of each of the protocols, their structure, and operation.
Delegates use the techniques taught in the previous sections to perform advanced Wireshark analysis on each of protocol.
This is particularly important as some Wireshark decode displays are specific to their respective protocols, and vary considerably from each other.
Delegates learn the importance of Wireshark advanced features when working in multiprotocol environments.
