- CCNA Study Notes: These are my original CCNA Routing and Switching Study notes (from around 2009). They are good bullet point summaries of some of the topics covered. Download CCNA Summary Notes
- CCNP Service Provider Study Requirements: I’m currently working to earn my CCNP SP. When I made this docuemnt, I had done one of the four necessary exams (SPROUTE 642-883), but found it difficult to source the necessary study material. As such, I made a spreadsheet listing the syllabus from the Cisco site for each of the other 3 exams, combined with the material (including book title and page number/chapter) needed to fulfil those requirements.
- TCP/IP vs OSI Comparison: A simple comparison of the TCP/IP and OSI Protocol Stacks.
- Layered Structure of a Frame: ok so… ARP is used to get MAC addresses but it’s not an IPv4 protocol? EIGRP and OSPF don’t use TCP? Port numbers, Ethertypes and protocols at all different levels. Check out this pdf to get a clear picture of the breakdown of the different layers when looking at a frame and how they interrelate. Ethernet, IPv4 has been shown as an example.
