Objective for this lecture

• Introduce ourselves
• to the course
• To the e-learning technology
• The resources available to you
• The course level and Detail
• Covered in detail CH 0 on-line curriculum
• Introduce you to my Site
• Introduce you to Packet Tracer
• Identify what is expect of me as an instructor-
  (What do you require)
• Identify what is expected of you as a student

Course Description

• Concepts, Terminology, OSI Model, IP Addressing,
  Subnetting, Ethernet, LANs, Protocols, Packets,
  Frames, Data Communications
• It introduces networking standards, concepts,
  topology, media and terminology including LANs,
  WANs, the OSI model, cabling, IP addressing,
  subnetting, network hardware and various
  protocols.
• This course also provides additional information
  on networking theory and protocols beyond that of
  the basic Cisco Networking Academy Semester 1
  course, leading to a more detailed understanding
  of networking.

Introduction Cont.

• I Rely Greatly On
• Routing Protocols and Concepts by Rick Graziani
  and Allan Johnson (Cisco Press) Cisco on line
  Course Material
• I will use the above material and the
  supplemental material form the above without
  referencing the same
• You may use this Material but please do not
  distribute the same
• The material is probably the property of Cisco or
  the above references

5
Course Information

• Introduction to networking protocols.
• Training is for a job HOW
• Education is for a career " WHY
• Those who know HOW will always have a job
• Those who know WHY will always be their Bosses
• The focus should be on Whys education and to
  help the you develop a real understanding of
  networking, not merely memorizing facts and
  commands.
• Focus on
• Protocols
• Algorithms
• Processes

6
What about Certifications?

• Degrees
• Certifications
• Courses
• Experience

• For those students interested in certifications,
  our goal is not only to help you obtain your
  CCNA, CCNP and other certifications, but to help
  you develop the knowledge and skills to live up
  to that certification title.
• We want to help develop networking professionals,
  CCNAs, CCNPs, etc., not just people who can pass
  the exams.

CCNA CCNP CCIE Levels (Very General)
CCIE PHD in networking --? ??? Well not really
but you get the point
Discovery High School/Tech School
Exploration College/University
8
The CCNA Exploration Routing Course

• CCNA and CCNP went through major revisions
• CCNA
• Separate courses for Basic Education - Discovery
  
• Advanced Education - Exploration
• Updating all curriculum including text and labs
• CCNP
• Still four courses
• CCNP is undergoing another review apart from the
  changes below
• Change 25
• CCNP 1 Advanced Routing (BSCI)
• CCNP 3 Multilayer Switched Networks (BCMSN)
• New Courses (Replacements)
• CCNP 2 Implementing Secure Cisco WANs (ISCW)
• CCNP 4 Optimizing Network Technologies (ONT)

9
CCNA Curriculum

• Exploration Advanced Education
• Discovery Introductory Level
• Refer to my Site for Details More on this later

10
What about Cisco Systems?

• 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 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.

Course Information
Some of the fundamental networking topics covered

• 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

• Network Topologies
• Transmission media
• Coax, twisted pair, fiber
• Modulation
• NICs
• Hubs and Repeaters,
• Switches and Bridges
• ISO and the OSI Model
• Cabling, UTP
• Collisions domains
• Broadcast domains
• Binary and Hexadecimal number systems

This will not be the last time you learn about
these topics in your networking education and
career.
14
Understanding not Memorizing

• Example Duplex mismatches on a switch
• Memorization Two connected switches must be
  configured with the same duplex setting.
• Understanding Understand the difference between
  full-duplex and half-duplex, along with Ethernet
  operations and slot time, TCP retransmission, and
  troubleshooting.
• Understand why this is happening and why the
  switches duplex settings must match.
• (I do not like auto settings you can challenge me
  on this or anything else PLEASE)

15
Self Evaluation

• What should I already know? I dont know any of
  this.
• Great, 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, email, word processing, windows, file
  management
• I think I know most, if not all of this
  fundamental networking information.
• See me off-line and we can discuss options.

16
Approach Will Adjust To The Class

• Repetition
• Documentation (PowerPoints, Reader, Books,
  Internet)
• Tools
• Ethereal Protocol Analyzer
• Packet Tracer
• Dont expect you to know something I dont cover
  in class.
• Do expect you to be able to extend your knowledge
  on your own.
• Encourage courteous participation but will not
  force it.
• No surprise tests.
• Suggestions Welcomed

My BackGround Your BackGround

• Computer Science/Networking Instructor, McGill,
  JAC, Dawson, ,etc
• All CCNA and CCNP courses, Data Communications,
  Programming, Operating systems, Security etc..
• Previous Work Experience
• Bell Canada
• Consulting for a Number of Smaller Companies

18
Herding Cats

• In some ways, the hardest networking course you
  will ever take.
• Not because it is difficult, but because
• A lot of new concepts
• These concepts become more clear in later
  courses, after you have seen them multiple times.
• Learning networking is like trying to herd cats.
  No one great place to start.
• The material this semester will make much more
  sense in later semesters. The more you learn
  about other areas, the more a certain topic makes
  sense.
• A lot of, You will learn more about that later.
• A lot of, Good question, but there is no short
  answer right now.
• Sometimes, See me off-line and I can explain
  it.
