  • 0:00:13 goodmorning everybody and welcome to the ccna boot camp
    0:00:19 a my name is Brian McGahan and i am going to be the instructor for this class
    0:00:23 littlebit about myself
    0:00:24 a i am from Chicago
    0:00:26 and i been in networking for above 15 years now
    0:00:31 and
    0:00:32 i originally started in Microsoft networking like a
    0:00:37 desktop support and pc support
    0:00:40 a then i got into like
    0:00:42 windows server type step
    0:00:44 went through the MCSE
    0:00:46 in NT.4
    0:00:48 which is quite well known probably 15 years
    0:00:50 and then eventually that laid me into ccna and ccnp
    0:00:55 so it definitely was good basis for
    0:01:01 the cisco steps that according to since then
    0:01:03 and we will talk about that today what are you know the expectation of
    0:01:08 a the level of technology that are going through the ccna
    0:01:12 and some of the pre-requisites and recommendations on different resources you can use the stuff like that
    0:01:18 but atleast from the person I see MCSE was a great
    0:01:21 a pre-reck for this
    0:01:23 because one of a this is a lot a general networking theory
    0:01:26 and specially like from the application level what we really trying to do in the first step with the network
    0:01:32 and from their i got ccie in routing and switching
    0:01:36 service provider and security
    0:01:39 a and
    0:01:42 for any question you guyes have my address is there bmcgaham@ine.com
    0:01:46 I will put this on the white board later as well
    0:01:49 so any question you have offline
    0:01:51 during the week or after class you Guy's feel free
    0:01:54 to contact me I am more that happy that hope with anything
    0:01:57 the only one thing i do want to mention is that the actual ccna exam
    0:02:03 or essentially any of the cisco exams
    0:02:05 there is basically an agreement that you will sign that just says don't tell people what are the actual questions are
    0:02:10 so when we will going to talk about what is the actual question on the exam
    0:02:13 we will talk about all the technology that are within cisco
    0:02:17 so pretty much anything is fare again feel free to ask me anything you want
    0:02:20 whether or a during the lectures whether we are going to work in lab time
    0:02:25 more than happy to
    0:02:26 and the end of questions and thats why i am here for
    0:02:29 a now
    0:02:31 along with a class participations key
    0:02:34 so really the more question you ask the more you can get into the class
    0:02:37 so if
    0:02:38 you know we spent hours and hours everyday answering questions thats fine i more than happy to do that
    0:02:43 so like i said just no you know don't feel
    0:02:47 don't hold back on anything else you want to ask me
    0:02:51 for offline questions there is a couple resources that we have
    0:02:54 one of them is a discussion forum
    0:02:57 which is at IEOC.com
    0:03:01 and basically this is a combination of a web forum and a mailing list
    0:03:05 so for
    0:03:10 the web forum you can just go to ccie forum where a lot of topics as well
    0:03:15 so you see this once for
    0:03:17 ccna in just different technologies topics
    0:03:21 but we will good about this
    0:03:23 is not only to
    0:03:24 you know to read and begin discussion with other people
    0:03:28 there is a lot of good information in the archives
    0:03:30 because the forum is gone upto for
    0:03:32 gone on my 10years now
    0:03:34 so if
    0:03:36 a there is a particular technical topic you want to get more information on
    0:03:39 usually you can go to the search
    0:03:42 and
    0:03:43 a you know search for particular keyword in get some good information on that
    0:03:47 there is a another one
    0:03:49 if you haven't seen this yet that is the cisco learning network
    0:03:54 is a really good forum
    0:03:56 for this type of discussions
    0:03:59 that is a littlebit more target into this type of level like ccent,ccna,ccnp type level
    0:04:05 so there is
    0:04:06 a there is lot of information here
    0:04:08 the only one thing i don't like about this one
    0:04:11 is the you can reply through email
    0:04:13 which is one of the features that our forum has that IEOC
    0:04:18 so if you ,you can go through the web and read all the posts and reply there
    0:04:23 a the advantage with this one now is that you subscribe to the individual lists
    0:04:27 and then if you want to go on you web browser reply condition reply through email
    0:04:35 the other one is our ccie blog basically just our a general technology blog
    0:04:41 and the there if this one is blogged that is ine.com
    0:04:45 main idea for this one is technical write-ups on different topics
    0:04:50 some of there is a littlebit more advanced that we are going to talk about this week
    0:04:54 but if you go to our web site
    0:04:57 which is ine.com
    0:05:00 you find links at the bottom you find links or both of them so this one is going to send you as blog
    0:05:05 and then to the
    0:05:07 a the online community IOC
    0:05:09 so
    0:05:10 we will talk about this is we go through the different topics to otherwise what are different resources that you can get access to
    0:05:16 because very much 99% of this step
    0:05:19 you could figure out just going through cisco's documentation by going through different online resources
    0:05:26 since this certification been around for so long there are so many resources that available for
    0:05:31 now almost of the point where you can over whelming to figure out
    0:05:34 how do i really narrow down my scope of what i need to learn
    0:05:37 for this forum even more some in order to learn inapply this into the field
    0:05:42 so we are going to take out like i mentioned a littlebit more practical approach to
    0:05:47 a to the topics
    0:05:49 where i will be going through
    0:05:51 a the theory
    0:05:53 for the topics which is definitely important to understand like how do you look really networks works whats the different between LAN and wide area network
    0:06:01 how does
    0:06:02 layer 2 switching work how does layer 3 IP routing work
    0:06:05 and also the configuration
    0:06:08 so we can go through a lot of practical examples on
    0:06:11 a this cisco ios command line and this switches command line
    0:06:15 you can also make this
    0:06:17 changes through a web interface GUI
    0:06:21 which is called the cisco SDM
    0:06:25 which is the router and security device manager
    0:06:28 so we will look at some examples by using this
    0:06:30 which is can i like a wizard for configuring the routers and the switches
    0:06:35 to do some of the basic operations
    0:06:37 but most of this we are going spend on the command line interface which like a telnet interface for you typing commands in the router
    0:06:45 and switches sending you feed back on it
    0:06:49 now like i mentioned the one of the big problems i had when i was first learning this step
    0:06:54 is you can rethrough the document you can rethrough lot of resources that say you know these are the commands you need to enter in order to a complex lists
    0:07:02 but then once you do that how do you know that is really works
    0:07:04 and how do you tide together that theory and the configuration to see
    0:07:09 how would really fix together
    0:07:11 and thats going to be the second two portion we are going to focus on
    0:07:15 is verifying of this step
    0:07:17 so what are the different show commands you can use on the routers and switches
    0:07:21 what are the different debug commands
    0:07:23 that if we run into problems
    0:07:25 what are the important to wants to use and then more important that how do we rethrough the output
    0:07:29 is this none of really not a good documentation that shows you you know if you have this problem run the show command
    0:07:35 where at this problem run this debug commands and look for this output
    0:07:39 so we will go through then only the theory i can mention
    0:07:43 how to configure the step and how to test to make sure that how its actually working
    0:07:51 now the general outline the class is pretty
    0:07:54 well follow along with the blueprint is for
    0:07:57 the ccna exam
    0:08:00 and there is basically three different variations that you can go through
    0:08:03 a to get the certification
    0:08:05 and if you go to
    0:08:07 cisco.com/go/ccna
    0:08:11 ccna
    0:08:13 its going to take you to the main certification page
    0:08:16 where its going to give you information like whats the
    0:08:19 you know what is ccna why i would want to get this to begin with
    0:08:23 whats the syllabus
    0:08:24 and then also
    0:08:26 you see here the different exam paths you can take
    0:08:30 chichi currently is either
    0:08:32 a ccna as a hole
    0:08:34 which is what we are going to doing this week
    0:08:36 or you can take it as two separate exams icnd1 and icnd2
    0:08:41 so if you look you either this for any of these i should say
    0:08:46 this one here the composite exam
    0:08:50 basically is the same outline
    0:08:52 as the other two but its going to be all in one
    0:09:11 so here if you go to cisco's web site
    0:09:13 a you no need to log in and you can create and account if you don't really have one
    0:09:16 then it tells you some general information about the
    0:09:20 the exam if
    0:09:22 if you never take a exam before never take another exam or it exam like Microsoft
    0:09:29 or something similar
    0:09:30 then
    0:09:31 you probably want to expansion time going through the exam tutorial
    0:09:36 which is shows you the format of it like multiple choice questions drag and drop questions
    0:09:42 just the basic interface of what the exam is actually going to look like
    0:09:45 but mainly whats important here is what are the exam topics
    0:09:49 so what is the technology that we need to talk about within the scope of
    0:09:53 ccna
    0:10:00 so first of from us
    0:10:03 describe how network works
    0:10:05 this is mainly we are going to be spending
    0:10:08 probably the vast majority today talking about just general theory of networking
    0:10:13 what are the differences between like the OSI model
    0:10:16 and th TCP/IP model
    0:10:18 a what are the some other basic
    0:10:20 differences between like LAN networks and WAN networks different types of a networking protocols
    0:10:26 so this is just more generic thing on networking
    0:10:30 once we get a littlebit further in then we get into the specifics of how cisco implements this technology
    0:10:36 so how do you configure switches how does VLANs work how does Spanning tree work
    0:10:41 also with
    0:10:43 a IP addressing and IP routing
    0:10:46 so we will talk about things like
    0:10:47 subnetting
    0:10:49 a different services for IP like DHCP servers DNS servers
    0:10:53 we will look at lot of example of this
    0:10:55 some of this you see specifically it says like configure DHCP and DNS
    0:11:00 then we do both on the command line interface and SDM
    0:11:03 so we are going to look at a number of variations of this
    0:11:07 what you may also find as you getting into a littlebit more on advance
    0:11:11 features of this
    0:11:13 let's say few example you no how DHCP is configured
    0:11:17 by give the general idea what is DHCP to begin with
    0:11:22 when you learning this step on the command line first
    0:11:26 a lot of time it take how to figure out
    0:11:28 what are the individual commands you need to do get this functional
    0:11:32 and thats where the SDM really help you a lot
    0:11:35 that is a kind of wizard that just works you through you know what are the different options you need to configure this technology
    0:11:40 but then you can work backwards from now
    0:11:43 so we will look at some cases where we go through the web interface of the SDM
    0:11:47 but then whats look at whats the result of the commands that are used on the CLI of the command line interface to actually that
    0:11:58 a next one i can configure verify troubleshoot basic cisco network operation
    0:12:02 here we actually talk about this step before we get into
    0:12:06 the configuration of the other topic
    0:12:09 because this is just like hurry get into the router
    0:12:12 a what are the different kinds of connectors you need use to talk to it
    0:12:17 how does the basic
    0:12:19 IOS interface work which is going to be for managing the routers and for managing the switches
    0:12:26 then we will talk about
    0:12:27 a network security a littlebit
    0:12:30 including access control list and network
    0:12:33 address translation
    0:12:35 where access list or ACL this is used for security and network
    0:12:40 where network address translation or NAT this is going to be used for
    0:12:44 a like largest scale implementation of addressing
    0:12:48 then we talk about littlebit about
    0:12:50 WAN links
    0:12:51 like what are the difference between the frame relay protocol and PPP or HDLC
    0:12:58 this is a really huge focus
    0:13:00 of the ccna curriculum
    0:13:02 more than just trying get into figure out whats the different between where the majority about
    0:13:06 a
    0:13:07 topics go which is on the LAN
    0:13:09 and then whats the difference between that in the WAN
    0:13:11 and does that change the something design and operation the network
    0:13:16 so its going to
    0:13:18 petty theorily closely follow that are long
    0:13:21 so today we mainly talk about
    0:13:23 what are the different pieces that make up a network
    0:13:26 a how does they fit in to the difference models they come up with the over the years
    0:13:30 and why would you want to even use that to begin with
    0:13:34 in this one the OSI models and the TCP/IP models
    0:13:37 i think its requirement by law
    0:13:39 that every book thats written on networking
    0:13:41 you have to start the first chapter that talks about the OSI model
    0:13:45 so if
    0:13:46 you know you been in networking before you have seen this step
    0:13:49 but in the long run these actually important especially when we get into the troubleshoot the network
    0:13:54 or to look at how do we build the network in a structured fashion
    0:13:59 it actually is go to lot of the times to fall back to that
    0:14:01 a the layered approach that the OSI or the TCP/IP models define
    0:14:07 we will also talk about
    0:14:08 some of the different requirements of network applications
    0:14:12 and then how do we interpret network diagrams
    0:14:14 and try to visualise
    0:14:16 what should be the end result of our network design what should be the end result
    0:14:20 like if i go to browse a web server
    0:14:23 from behind the scenes point of view how does they actually work
    0:14:26 is it goes through the different devices on the topology different devices on the network
    0:14:33 we will then talk about the
    0:14:35 a the LAN switching
    0:14:37 get into the some specific to the configuration of the catalyst switches with ethernet
    0:14:42 then as i mentioned IP addressing
    0:14:45 we are going to focus mainly on IPV4 this week
    0:14:48 but we will talk about the newer version of that which IPV6
    0:14:53 then routing is going to be very big
    0:14:56 focus as well
    0:14:58 where are some other different dynamic routing protocols like RIP
    0:15:01 EIGRP and OSPF
    0:15:03 why would we want to use one versus the other
    0:15:06 now thats going to effect the
    0:15:08 a some other network design
    0:15:10 there is a littlebit focus on wireless
    0:15:13 for this exam
    0:15:14 there is a separate wireless ccna certification
    0:15:18 so its more just touching on the general idea of what is wireless
    0:15:22 and if you want to get more information on that
    0:15:24 they would point you towards the wireless track
    0:15:26 a something is going to be true with security
    0:15:29 where we will talk about some of the basic requirements of security on networks
    0:15:33 but most of that
    0:15:34 and if you want details on it you would go towards ccna security and then eventually ccnp security,ccip security
    0:15:45 case again very much
    0:15:47 a pretty close to on the
    0:15:50 a the blue print there as well
    0:15:54 now as i mentioned everyone is also going to have an access to
    0:15:58 routers and switches to use this week
    0:16:01 littlebit later today we will talk about specifically how we get into those
    0:16:04 a what are the application we need to talk to the routers an switches
    0:16:08 but specifically there is going to be a five routers
    0:16:12 that are mixed 2600XMs
    0:16:15 because this is specific a hardware platform that we were using
    0:16:18 which has both an ethernet and serial interfaces
    0:16:22 which we will talk about it in detail what is that really mean over layer
    0:16:26 then those a 3 catalyst switches
    0:16:30 which are 3550s switches which means that both layer 2 and layer
    0:16:34 3 switches
    0:16:36 which we will going to tomorrow detail what does that mean
    0:16:38 which referring switching layer 2 switching and layer 3 switching
    0:16:41 and there is also a test pc
    0:16:44 that are going to be using for
    0:16:46 a testing a bunch of different applications
    0:16:49 so like TFTF server,web server, DNS,DHCP
    0:16:54 so you have a better idea of
    0:16:57 if i was on my laptop here and i browse to a web server
    0:17:01 when i look at that
    0:17:02 from my router configuration and from my
    0:17:05 switch configuration whats the end result it
    0:17:08 because sometimes if you look at just the network on its own
    0:17:11 like build a network with switches and routers you can't really visualise what's the end result
    0:17:16 and really the end result is always going to be based on what is the application doing
    0:17:21 because the whole point of network is to somehow service the application
    0:17:25 whether that's web browsing or financial data
    0:17:29 or phone calls that are going over the ip network
    0:17:33 ultimately what we will worry about is the actual application
    0:17:38 so as I mentioned the rack access is going to be 24
    0:17:41 24/7 availability
    0:17:43 so later this evening or anytime you want to go through these examples
    0:17:47 I will have access to do that as well
    0:17:51 now some of the resources that we will be going through
    0:17:55 want to talk about just
    0:17:56 some of the recommended readings
    0:17:58 for after class
    0:18:00 that you want to go back through
    0:18:02 and then also we are going to spending a bunch of the time in the cisco's website
    0:18:06 which if you much time on it before
    0:18:09 you will see its not very self-explanatory how to actually navigate through it and how to find information on it
    0:18:16 but the thing
    0:18:18 so many free resources you can find just by using cisco's website
    0:18:23 and
    0:18:24 by knowning how the information is
    0:18:26 categorised
    0:18:28 pretty much every thing you could need to know is on there
    0:18:31 now whether its going to be neatly written as these
    0:18:35 these introductory ccna
    0:18:38 like the icnd and icnd 2 books
    0:18:41 depends on what particular topics we are looking at
    0:18:43 but we will spend a bunch of time navigating through the website looking at how the documentation works
    0:18:49 how can you find information about the actual hardware
    0:18:52 like I am trying to figure out what kind of router do I need for this application
    0:18:56 or look at how to go to that as well
    0:19:02 now for
    0:19:04 recommended readings
    0:19:06 once that are specific to the exam mainly is going to be the one is that
    0:19:10 you see the printed set there
    0:19:13 which is the
    0:19:17 the cisco press ccna
    0:19:19 certification library it is called
    0:19:22 and there is actually two versions of this
    0:19:25 the one that we have is
    0:19:31 this one here is by Windel Odelm
    0:19:35 who
    0:19:36 writes of different titles for cisco's press
    0:19:39 is a really good author puts a lots of stuff into a very plain language to make it easy to understand
    0:19:45 but basically what is says it that the two book set that covers both
    0:19:49 the icnd 1 and icnd 2 exams
    0:19:53 now you will that some of this is going to be
    0:19:57 pointed towards the theory, like what is networking what is switches what are routers
    0:20:02 bu the key is that this is
    0:20:03 specifically for the exam
    0:20:06 so a lot of times you will topics that are
    0:20:09 very specific to passing the exam
    0:20:11 not the actual questions, but just the type of specific information you need for the test
    0:20:18 what we are going to mainly focussing on this is the technologies
    0:20:22 where if you understand the technologies then should be able to pass the exam
    0:20:26 because how they format the question
    0:20:30 you really understand how switching works or really understand how routing works
    0:20:33 then its not going to be a problem
    0:20:36 but these two books set is really good
    0:20:39 there is a another one that is the self-study guides
    0:20:43 which is kind of similar to this
    0:20:45 ccna self-study
    0:21:08 which I want to say is the
    0:21:16 ccna preparation library
    0:21:18 so they separated into two different
    0:21:22 categories where this one is learning the topics
    0:21:26 and this one is preparing for the exam
    0:21:28 so the books set we have here is that one is specifically gear to the actual exam
    0:21:33 this is here the preparation library is a little bit
    0:21:36 little bit more general
    0:21:38 that focusses more just on the technologies of networking
    0:21:42 and you could use this to prepare for the exam
    0:21:44 like I said the other one is little bit more focussed towards the format of the actual questions
    0:21:51 another thing that lot of people use is
    0:21:54 different types of practice
    0:21:56 questions of practice exams flash cards
    0:21:58 you will find that there is couple of cds that are in these books set
    0:22:02 they go through practice exams
    0:22:04 this is going to basically be your very last step
    0:22:07 in the preparation for the exam
    0:22:10 so may be a week or two before you schedule the exams go through a couple of these practice exams
    0:22:15 just to see the format of the questions
    0:22:18 but you don't want to spend too much time here
    0:22:20 before you go through the theory
    0:22:23 so we are not going to spend a lot of time this week going through practice questions
    0:22:26 its kind of something you can do on your own with
    0:22:29 these resources that you have available to you
    0:22:34 that the other
    0:22:35 portion is
    0:22:37 going to be things that don't really relate
    0:22:39 specifically to cisco networking or don't relate to the exam
    0:22:43 but are more clear towards just networking in general
    0:22:46 now the ones that I have on the list here
    0:22:49 if you were to read all 3 of these
    0:22:53 it could
    0:22:54 easily take you 6 months to get through them or more
    0:22:58 so lot of them are really detail text which are kind of like almost college level text that are related to networking
    0:23:04 but pretty much any of these 3
    0:23:07 this is something that through out your career you can always come back to as a reference
    0:23:12 and if you look at any of these 3 like the
    0:23:17 I will say like amazon the
    0:23:21 inter connections
    0:23:26 bridges, routers and switches
    0:23:31 pretty much all 3 of those that I have on the list have 5 star ratings
    0:23:35 anywhere that they sell the book
    0:23:38 and you will see that
    0:23:39 a lot of them are older text
    0:23:43 I am not sure what says the
    0:23:45 this one is from 99 and this is the 2nd edition
    0:23:48 but the key is the stuff that these text cover
    0:23:51 they don't change
    0:23:53 so its the same stuff thats been going out in networking for the past 20-25 years
    0:23:58 where
    0:23:59 like this offer for example Radia Perlman
    0:24:03 she wrote what's known as the spanning tree protocol algorithm
    0:24:06 or STP
    0:24:08 so this is one of the topics that we are going to talking about this week
    0:24:12 but the key is that she wrote this book about switching
    0:24:15 and every switch that runs ethernet runs this protocol that she wrote
    0:24:20 so pretty much she an expert on this is
    0:24:23 the same is going to be true with the other two the internetworking with tcp/ip and tcp/ip illustrated
    0:24:30 these two
    0:24:32 are authors, one them is
    0:24:34 Douglas Comar
    0:24:36 and the other is
    0:24:42 i will get everyone of these slides afterwards
    0:24:47 so you don't have write all the
    0:24:49 like the books and stuff down
    0:24:51 this one here is really good
    0:24:55 which talks about the general theory of
    0:24:57 tcp, and the general theory of ip
    0:25:00 we will go into a lot of specifics of these, this week
    0:25:04 but this is part of a series
    0:25:06 where this one just says
    0:25:09 what the general theory behind ip networking, what are the protocols that make up
    0:25:13 what we call ip stack or the tcp/ip stack
    0:25:17 from here he goes on to a couple of more books which are the actual implementation
    0:25:22 like from programming code how do you write ip
    0:25:26 for my web client in order to talk to your web browser
    0:25:29 so depending on
    0:25:31 where you want to go
    0:25:33 like in your career of networking or in the field
    0:25:36 if you were to get into actually
    0:25:38 designing applications and designing programming
    0:25:41 than
    0:25:42 there is lot of more detail that goes into this the volume 2 and the volume 3
    0:25:48 in this case server programming and application BST socket version
    0:25:52 so this means like how do you actually implement ip on Linux or Unix
    0:25:58 same is going to be true with the other one which the tcp/ip illustrator
    0:26:11 which is by this gentleman Richards Stevens
    0:26:14 so he has a another set that is similar
    0:26:17 first book that just talks about what are the protocols that make up ip
    0:26:21 so whats the theory behind them
    0:26:23 what are they suppose to do
    0:26:25 then the ones beyond this go into the actual implementation so like the programming logic behind ip
    0:26:32 and then further than that
    0:26:34 transaction this is like the applications http would be for web servers
    0:26:40 this one is for time
    0:26:43 network time protocol
    0:26:46 NNTP that is for
    0:26:49 network news
    0:26:52 but the key is that
    0:26:54 these 3 in general
    0:26:56 are kind of like bibles that come along with ip networking
    0:27:01 so wouldn't necessary have to read all three of them
    0:27:04 but if you pick up one of them you can always use it as a reference throughout your career
    0:27:08 and for lot of the details that you want to know
    0:27:11 like we will talk about today
    0:27:13 in the OSI model
    0:27:16 what are the different
    0:27:17 what are called the packet data units or the protocol data units
    0:27:21 that make up
    0:27:22 like ethernet vs ip
    0:27:24 if you wanted to see actually what is that look like from programming point of view
    0:27:29 these books would be
    0:27:31 the type of resources that we would use
    0:27:33 so that level of detail we are not getting into, we don't need to look at
    0:27:37 what is an ip packet look like, what is an ethernet packet look like
    0:27:41 there are tons of resources that you can see after class to go through that
    0:27:45 but
    0:27:46 keeping things in mind once you go through the
    0:27:49 the general cisco press stuff
    0:27:51 if you want to get more information on it them I would definitely recommend it to go through
    0:27:55 atleast one of these 3
    0:27:58 we will also spend some time going through
    0:28:01 what's
    0:28:02 some of the technology information that's available on cisco's website
    0:28:07 so if you go to
    0:28:09 cisco's main website
    0:28:11 what are the main sections is here under support
    0:28:16 this is where the lot of the product documentation that they have is
    0:28:20 and lot of the general technology documentation
    0:28:24 so if were to go to support
    0:28:26 and then go down to
    0:28:29 the bottom of the page here
    0:28:31 there is a link that says configure
    0:28:37 now I am not going to go through all of the details of this right now
    0:28:40 as we go through different topics, like as we go through ip routing as we get through layer 2 switching
    0:28:45 this here is where cisco documents how do you use all other products
    0:28:49 and how do you use all of the technologies
    0:28:52 within the scope of their specific implementation
    0:28:55 so how they do ospf vs how
    0:28:58 another vendor does, how they do lan switching versus how someone else does
    0:29:04 but this is going to be
    0:29:05 a lot of good examples of how would you configure something
    0:29:09 how would you test that it is working
    0:29:11 or under the technology here
    0:29:14 like lets say lan switching for example
    0:29:17 technology lan switching
    0:29:19 then ethernet
    0:29:23 all ethernet
    0:29:26 and then all technology information
    0:29:33 so from here you would find a lot of links
    0:29:36 that go to external resources
    0:29:40 like in the case of running gigabit ethernet over copper interfaces
    0:29:44 this is to find by a standard that is known as 802.3ab
    0:29:49 so if you wanted to see the actual specifications of
    0:29:53 how does running this protocol over
    0:29:55 this particular type of media different than its other variations
    0:29:59 you will see that this is one place that you can go for a lot of these links
    0:30:03 so you wouldn't necessarily read this end to end
    0:30:07 you will see its just
    0:30:08 mass the amount of technology documentation thats on cisco's website
    0:30:12 but the key is that if you know how to get
    0:30:15 through some of these pages
    0:30:16 then
    0:30:17 you may be able to find some of the answers are aren't' as clear in some of the these books or some of the other resources that we are going through
    0:30:24 so as we get to the specifics of these different protocols we will go through the technology documentation
    0:30:29 so a couple of key things that is going to show
    0:30:32 one is going to be frequently asked questions
    0:30:35 which talks about
    0:30:37 what is some of the problem
    0:30:38 are common problems that people run into the field
    0:30:41 if I am implementing
    0:30:43 lan switching
    0:30:44 what are common problems I need to look out for, and what are ways I can get around this
    0:30:49 same is going to be true of like ip routing the different ip routing protocols
    0:30:55 the other one is going to link to different types of standards
    0:30:59 like I mentioned before the
    0:31:01 the gigabit ethernet was defined by 802.3ad
    0:31:05
    0:31:08 but these may be some of the questions they would ask you in the exam
    0:31:12 what's the
    0:31:13 standard no. of the gigabit ethernet
    0:31:16 what's the standard no. for gigabit ethernet for copper
    0:31:19 this is the type of stuff that cracked questions are going to cover
    0:31:21 when I am going to spend a lot of time trying to memorise stuff like this week
    0:31:29 you also see they go through
    0:31:31 design guides
    0:31:33 which there is couple of we are going to look when we get to
    0:31:37 the lan switching and also the routing
    0:31:40 that are good kind to give you a over all picture
    0:31:43 of how does everything fit in together
    0:31:46 so why would I want to use
    0:31:47 ospf versus eigrp or why would I want to use these particular
    0:31:51 variations of layer 2 networking versus the layer 3 networking
    0:31:55 and even if you don't get into the minigrade details behind the individual technologies
    0:32:01 is just a good
    0:32:02 umbrella to figure out
    0:32:04 what's the over all idea why do you want to use this in the first place
    0:32:11 we will also spend some time going through
    0:32:13 the actual product documentation
    0:32:16 that talks about how do actually configure these different features in
    0:32:20 the routers how do you configure them in the switches
    0:32:23 this is going to be made up of a couple of different portions that we will go through
    0:32:27 the mainly
    0:32:29 two portions we look at one is called the configuration guides
    0:32:32 one is called the command reference
    0:32:34 where configuration guides says if I want to implement a dhcp server
    0:32:39 this is the individual steps you need to go through in order to do that
    0:32:42 where the command reference would say if you issue this specific command this is what its going to do
    0:32:47 and then these are the different options that you can change on it
    0:32:51 so though have different uses depending on the exactly what we are trying to accomplish
    0:32:55 but the more familiar that you can get with
    0:32:57 the configuration guide in the command reference
    0:32:59 a lot of questions you will be able to answer to yourself just by going through the
    0:33:03 the no. of different documentations that they have
    0:33:12 so some of the other portions like the master index with these notes we will talk about it later when we get to specifics of them
    0:33:20 so the main thing is that
    0:33:23 everyone is going to have access to equipment
    0:33:25 and that's where we are doing most of our discussion is
    0:33:28 on the cisco ios command line on the switches command line
    0:33:32 we are looking how to go through the different configurations
    0:33:35 what are actual end result of that how do we test it
    0:33:38 and then how does this fit into some of the theory
    0:33:42 so as the supplement of the topics that I am going through
    0:33:45 you are still going to need to read a lot of material that is related to this
    0:33:49 which is where the certification library is come in the printed book
    0:33:53
    0:34:04
