1 EET-1301 FUNDAMENTALS OF NETWORKING COURSE INTRODUCTION Tim R. Moore

2 2 For the courtesy of others Please turn off all laptops, PDAs, cell phones. Cell phones may be put on vibrate mode, but please take the call outside of the room. Please do not text message, chat, etc. with cell phone or other devices.

3 3 Introduce yourselves! Tell us: 1. Your name 2. Family 3. City 4. IT Background 5. Your goal at CCC 6. Tell us something about yourself that few people know about.

4 4 My description of this intro course: Introduction to networking protocols and how networks work. Networking Engineering 101 You are being educated for a career. Not trained for a job. This is not a job training course. The focus of this class is education and to help the you develop a real understanding of networking, not merely memorizing facts and commands. In semester 1 we will focus on: Protocols Algorithms Processes

5 5 You must decide your goal You must decide what level of investment you are going to make in this four-part series of Cisco courses: Are you making a small investment... or are you - all in? CCNA 1-4 College Credit? CCNA 1-4 CCENT Certification? CCNA 1-4 CCNA Certification? Time investment (can be considerable) Effort investment (can be considerable) Sacrifices you are willing to make: Leisure time activities Family (make sure everyone is onboard with your decision) Work related

6 6 You must decide your goal CCNA 1-4 College Credit? CCNA 1-4 CCENT Certification? CCNA 1-4 CCNA Certification? <10% <10% >90% Historically, what percentage of students do you think choose either of these three goals at the beginning of the four Cisco course series?

7 7 Historically, what actually happened? CCNA 1-4 College Credit? CCNA 1-4 CCENT Certification? CCNA 1-4 CCNA Certification? 80% 10% 10% Where do you think the majority of students are at the end of the four Cisco course series? Usually, only about 20% of students even attempt the certification exams.

8 8 With your help we can reverse these numbers! CCNA 1-4 College Credit? CCNA 1-4 CCENT Certification? CCNA 1-4 CCNA Certification? 80% 10% 10%

9 9 Where do you think my focus will be? CCNA 1-4 College Credit CCNA 1-4 CCENT Certification CCNA 1-4 CCNA Certification 80% 10% 10% My goal will be to help as many people be as successful as possible! DO NOT DROP YOU DROP, I FAIL!

10 10 Up and Beyond I will give optional and recommended assignments to students to help them reach the level of comprehension and understanding needed to pass the certification exams. These optional and recommended assignments have no points or grade associated with them. They are simply added value activities. These would require an extra time and effort commitment. You can get credit for these Cisco courses by testing out. You can do this by passing the certification exams.

11 Key: Understanding - not Memorizing 11

12 12 What am I going to learn in all four Cisco Academy semesters? Describe how a network works (semester 1) Implement an IP addressing scheme and IP Services to meet network requirements in a medium-size Enterprise branch office network. (semester 1) Configure, verify, and troubleshoot basic router operation and routing on Cisco devices (semester 2) Configure, verify and troubleshoot a switch with VLANs and interswitch communications (semester 3) Explain and select the appropriate administrative tasks required for a WLAN (semester 4) Implement, verify, and troubleshoot NAT and ACLs in a medium-size Enterprise branch office network. (semester 4) Implement and verify WAN links (semester 4) Identify security threats to a network and describe general methods to mitigate those threats (all semesters)

13 13 Course Information Semester 1 Some of the fundamental networking topics covered: Network Topologies Transmission media Coax, twisted pair, fiber Cabling, UTP Modulation NICs Hubs and Repeaters Switches and Bridges ISO and the OSI Model Collisions domains Broadcast domains Binary and Hexadecimal number systems Ethernet frames MAC addresses Layer 2 communications IP Addressing and Subnetting **** Classful and Classless addressing Introduction to Routers and Routing Protocols ARP ICMP DHCP and DNS TCP and UDP This will not be the last time you learn about these topics in your networking education and career.

14 14 What about Certifications? Experience + Certifications + Courses/Degrees = Salaries To earn CCNA, must pass two exams: ICND1 (CCENT) + ICND2 OR Just one big CCNA exam

16 16 Should you be here? What should I already know?... I don t know any of this! Perfect! You are in the right class But you should already have basic computer literacy knowledge and skills: Hardware, software, CPU, RAM, ROM, disk drives, interface cards, bits, bytes, software development WWW, , word processing, windows, file management

17 17 My Teaching Style (do unto others) My approach: Simple minded (me) keep it simple Repetition, repetition, repetition... part me, part academy. External Resources (PowerPoints, Podcasts, Books, Internet, YouTube, Videos, Labs). I m not a control freak. I m not going to lecture you any more than necessary. This is a hands-on class if at all possible. Hands-on tools to learning: Wireshark Protocol Analyzer Packet Tracer Network devices

18 18 My Teaching Style (do unto others) My approach: I Don t expect you to know something that I don t cover in class. I Do expect you to be able to extend your knowledge on your own ask questions research independently for answers. I Encourage courteous participation but will not force it. No surprise tests relax! But, keep up with the class.

Certifications: Cisco Certified Network Associate (CCNA) Cisco Certified Entry Network Technician (CCENT) CompTIA A+ CompTIA Network+ CompTIA Security+ Others outside of networking AAB, CIS, Programming Major BBA, Management Major M.Ed., Curriculum & Instruction

20 20 Learning IT is like... Herding Cats Concepts, terms, devices... all going in different directions at the same time. Be PATIENT you will learn it over time. Jump in with both feet: keep trying, don t quit, and you will be successful. If you are the type of person who needs constant positive reinforcement, it will be difficult. You will feel lost at times; you will get frustrated often. This is a marathon not a sprint. Expect comprehension to come in clumps. Lots of aha moments after feeling overwhelmed for awhile. The good pay isn t because it s easy to learn. If it was easy, everyone would be doing it.

21 Student Responsibility 21

22 22 Student Responsibility Your education and success is your responsibility you get the credit for your success! You are working for You, Inc. Come to class prepared: Come to class and be on time Pen(s) and Paper Take Notes helps to stay focused! Let me know if I m going too fast! (Guys can t multitask well) Index cards (flash cards) Organized: prior handouts, notes, etc. Read the chapter in advance read multiple times!! Technical reading is difficult. Don t read like a novel.

23 23 Student Responsibility Outside of class: Schedule a time for reading and homework (no cell phones distractions) Find others to study with form a study group Missing class Ask other students BEFORE the next class what you missed Check the website: Late assignments I can t take late work unless extenuating circumstances. This is for YOUR success.

24 24 Student Successes You, Inc. Remember, you are developing your brand because you have competition for the career that you want. Live the standard or living that you want to live. I have many successful former students: Students who are now working as network engineers/administrators and/or continued on to a fouryear university. Some of these students had challenging disabilities, disadvantaged life circumstances and personal issues.

25 25 Student Successes Some common things they did: Made their education a priority set goals. Took baby steps. Expected it to be challenging. Found a way to make it to class - RTA Took as many classes as possible with available time Organized and prepared Took advantage of internships or found their own opportunities Worked hard and kept trying when they came upon obstacles. Anyone can find excuses. Anyone can find many, many reasons to quit that sound perfectly reasonable.

27 Successful Students

28 Succeeding in EET-1301 Preparation and organization Pen/pencil, notebook/binder Taking notes Print slides Read textbook or online text (I prefer online) Do research question what you don t know Grades Not the only deciding factor. Grades aren t everything. Soft skills & hard skills - employers want both! Self Motivation Initiative to work Enthusiasm for job Professionalism/Organization skills Communication skills and working with diversity 28

29 29 What about this Cisco? Is it relevant? Question: Does this and some of the other courses focus only on Cisco Systems networking? Does it apply to using non-cisco equipment? Answer: All of the information in EET-1301 and more than 95% of the courses that use Cisco equipment applies to general networking knowledge. Cisco, Nortel, Lucent, Alcatel, Foundry, Juniper, and others, all apply industry standards protocols from IETF, IEEE, and others. Typing the commands on the equipment is very easy. Understanding what is happening; how to design, implement, and troubleshoot networks is the difficult part.
