Getting Started with Cisco Packet Tracer 7.3

hi folks I'm here today to talk to you about Cisco black tracer and in particular 7.3 so if you haven't seen packet tracer before or if you're new to it it's essentially a network design and simulation and monitoring tool that you can use for networking computer network studies and cybersecurity and Internet of Things so it's actually believe it or not Cisco back tracer is free now you will need to go to the cisco packet tracer so you look pop-top the link appear netacad comm and it's available as you can see on Mac which I'm using here today it's also on Windows on Linux and I've also got my phone here in my iPhone and you can see that it's actually available on mobile devices now so you can have lots of fun with it on different devices so what I'm going to do today is I'm gonna really just explore the interface and particularly seven points right there are some kind of new little little things that you should get to know and if you're gonna be spending some time with pocket tracer so I'm gonna kind of just walk through a quick example here today so essentially let's let's get started and I'm gonna talk to you first about this logical view that were in at the moment so in order to add things to packet tracer we literally just come down here and you can see we've got network devices we've got end devices we've got even components and us pocket tracers developed they've added more and more various different devices and so forth so what I'm going to do is I'm just going to go in and I'm gonna add in a first for example Arusha and I can pop it here in my topology I can go in and I can add for example switches so for example I might add a layer 3 switch so don't worry about too much about that the terminology just yet and also let's add an access layer switch and also what I can do is I can add an end device here a PC and from here I can actually start to cable up these devices so I can click on this little connections symbol and I can start to actually use these cables now I'm not sure on the cables and this is a copper straight true and I could use this little and that this connection button it looks like an electricity bolt you can use that too awesome actually cable up but what I like with this is it gives you flexibility with the copper straight route to actually choose the port and then choose the switch port so I'm just gonna choose any port here to connect up and you can see that on the PC goes green straight away and on the switch it's just going through a couple of different steps and maybe I'll come back and talk about that those steps is going through another day but essentially then I need to use a crossover cable between two switches and so I'm gonna connect here two gigabit zero 1 over two gigabit and we can choose 101 in this case so many Gigabit Ethernet ports on this layer 3 switch and what's interesting about this switch is that and it won't go this won't do this these ports won't come up at the moment and one of the reasons why it won't come up is with this by default you actually have to add in manually parasol's so you can see here you've got an AC power supply you have to drag this in once I drag this in I'll give it a little bit of time but we actually should see these going from this rare red or down state into a green state okay so it might take a minute or two to actually do that now you can see it's going through the process and that will eventually hopefully turn to green and lastly what we can do is we can cable up from our multi-layer switch ok - are you sure now what we'll see with this one this is because Reuters defaults thanks for reports I shut down this won't come up until I actually go in and start configuring my route so that's a security principle that by design so essentially they're they're not gonna come up so while that's happening you can see and this is just about to go green very shortly there's also another view that I'd like to show you because at the moment we're in what's called logical view but what's great about packet tracer is if you haven't had an experience with hands-on real equipment you can actually go into this physical view and this will bring you into kind of citywide view if you click on that you can go over then into an office view they click on that you can see then I can actually there's my PC one in this case and you can see it actually we've got and what's called a rack view and in this rack view we can see here is our equipment that we've actually added and to our topology and you can see in this case there's our rack I can so I can zoom out of but if I like to see all of them the pieces in the rack or I can zoom back in so I can see in this case I've got my switch I've got my multi-layer switch I've got my route shirt for example and I've also got Power Distribution power and up here at the top to pair my various different devices and what's really nice about this is we can get to our for example if I click on the switch I can change for example so again if I wanted to change that if I wanted to say this is switch 0 or switch 1 okay I can also give it a host name here I can do that and once I click on the X it will actually change so it's a she updated that immediately if I wanted to change one multi-layer switch and call it something else I could indeed go back to the config and I could call this multi-layer switch maybe two and essentially I could close that and you can see it's updated here if I wanted to change my Russia okay I can even believe it or not if I'm if I'd like to get more experience with this physical view I can actually go in here and shoes so if I wants to add let's say for example another switch let's say another access switch for example I can go here and I can literally click on that and in goes my switch so once I click on that switch maybe I'll call this switch - for example you can see it's still booting up so I can't get to and the prompt just yet have to wait until it boots so if I wanted to I could wait and I can now go switch to for example and you can actually add believe-it-or-not pcs to this design so for example if I click on here at the PC and so my devices and click PC I can literally just click here and what this will do is if I scroll down you can see I've added a PC here ok so once if I then connect believe it or not to this and to for example let's say I wants to connect to my new switch to this case can actually do it physical physical mode so I could click on the the end devices and the connections I can go straight through click on my PC click fast the internet and then what I will do is I'll click on switch to and then switch to ask me what pour TOI connecting so in this case I'm going to say fast internet zero one so you can see actually what I've added that it's added the connection in there so that's pretty cool and if I hover over it I can see exactly my configuration so I can see in this case I'm in fast internet 1 also I can see if I hover over and switch 1 I can see where it's going and where it's what port it is and where it's going to and likewise with the multi-layer switch now as I as I do this more in physical mode I can also go back to my logical view and I can see that this is acting now again I might need to move this across here and just drag this to where I want it and perhaps you can see the moment switch 1 and switch to they don't have a connection now can either do it from logical view or I could go back to physical view where I could literally go and say ok I'd like to connect up between maybe gigabit ports here so I'm gonna select gigabit 0 2 and maybe I'm gonna connect down to my switch 2 and let's connect this into gigabit 0 1 so once I do that you're gonna see then these two connections wants to go back to logical view there comes back my connections that are now connected up so just looking at this diagram now so that's if you like the difference between logical and physical view and so the best idea or at best advice I'd say is play around with that and but let's now modify some basic and packet tracer preferences so at the moment in physical view I could hover over and I can see the ports but what I like to see is you can do that by hovering off devices here as well you can see what devices so I can see gigabit zero one you can see is in an upstate for example but I'd like to see on the screen exactly what ports are going from PC wanted to this switch and from PC to into this switch so what I can actually do is I can go up to packet tracer and I can click on preferences and what I can do is I can click on this little button called always show port labels in the logical view and what I like about this is it shows it exactly where the cables are going into between the switches and I always leave that on when I'm configuring any devices now if you're on a Windows PC you'll be options and preferences ok but just have a look around for this myth I'd say explore these options and again don't be shy to actually try very simple things out you can add for example D Peaks the exact models after various different switches so you can see this is an is or into credit service Reuter and you can see in this case a 2960 switch but sometimes it can get a little bit too much text on the screen so but I like to just keep that the pork labels shown and so also if for example if you're very new to this and you want to say well I'd like to see traffic flowing across this network how do I do that well in actual fact that's very very simple what we can do is we can go into PC one go to desktop and I can simply just go into IP configuration and we can give a static IP address so I can put this on the one 92168 dot one and let's say this is the temp and I've just picked that roundly and I'm gonna use a slash 24 subnet mask or 255 255 255 dot 0 subnet mask and so that's temp and what I'm going to do is I'm going to go over to my friend here PC 2 and I'm gonna pop this guy on the same network the one 92168 dot one dot let's call him 11 and give him the same subnet mask so this guy's gonna be 191 safe 1.11 whereas pc 1 is going to be 192 168 1 dot 10 so they're both on this one ninety one state one network that signified by this subnet masks so this first 24 bits and the last section is the host part so now what we can do is we can actually create a basically now that we've put an IP address where we put some basic device configuration in we can simply add a simple PDU by clicking this that lamina and from here I can go from here to here and what will happen is essentially I'll be able to send a message now if you do that it looks like nothing's happened and that'd be that can come become frustrated but if we look down the right-hand corner and we can see we've got a real-time mode and a simulation mode now after moment were in real-time mode and in order to see if that was actually successful what we actually need to do is we need to click down here in the right hand corner we can see this little arrow if I click on that I get all of the options and you can see in this case the the source from pc1 to pc2 and it was an ICMP so this is an essentially a ping message you can see that this status of that was successful so indeed if I try that again from pc1 to pc2 we should see another successful message so this all looks good and now if I wanted to go one step more detailed I could go into for example simulation mode or it could actually dig into the details office now what I like to do before I go into these simulations I'd like to get rid of those tests that I've done previously and click into simulation and you'll get an extra simulation panel that will come up what I like about this is you can now select from pc1 to pc2 and what you can actually do is you can step chose so at the moment it's getting ready to sell this ICMP message that's gonna go from pc1 to pc2 so what I can actually do is I can click on here I can play it awesome Ashton or I can step through this one stage at a time you can see at the moment or kind of like in this pause stage so what I can do is I can press play once and I can see my message going across from pc1 optimized first switch one and in this we can actually click on this and this is called the PDU if you like this is called a PDE with a protocol data unit and what we're seeing here is the seven layer OSI model and what we what we notice here is that we can see in this case the first two layers because again switches on these access layer switches these work at their one and layer two and we can actually as we delve into this we can actually see the inbound message so this again this is the frame coming into the switch and we can also see the outbound but with the inbound we can see that the protocol that have to be used here layer 2 or the data link layer in OSI speak its Ethernet 2 we can see some details about first of all the source MAC address so back to my PC one go into the destination address and that has to be in this case PC 2 and we can then go to the layer so this going up into layer 3 now we've got IP this is inside our IP bucket and again we can see now our source IP and our destination IP and on top of this IP message what we can see encapsulated is our ICMP message so this is everyone's color echo request and if we press play again what we'll be able to see well close that down for a moment we'll see going across from switch 1 2 switch 2 and again if we want to dig into that we can see give the envelope inbound and outbound and we can basically then just added that there we can click on here it goes to PC - what - PC - you're gonna do it's gonna reply to this it's gonna send an echo response or an echo reply so now what's gonna happen is if I press on this and dig into this it's gonna show us and the message coming back now and I've just need to just move this out so you can see it again and just make that a nice bit bigger in the inbound we can see actually if I dig into this now I can see the comment from the source address so that's PC - now going to the destination address so again this is in this case this is gonna be PC one and if I keep pressing playlist I now can basically I can see that this has been successful so I can see that my little small test network between these two switches obviously I've got a multi-layer switch in Arusha here but between that's only needed to pass from and literally across this local area network from pc1 to pc2 and i can see most as successful okay I hope this has been a useful for you if you do find these videos and useful please subscribe and I'll be sure to put up some videos in the near future thanks for watching and talk soon
