Packet Tracer 7.2.2 for Beginners - How to

okay here we go here's a quick introduction to packet tracer packet tracer is network simulation software where we can emulate different devices and simulate a network in action you have the mainstage here and basically you drag-and-drop devices connect them together and then watch how communication works from device to device you can use end devices like PCs and phones and you can also use intermediary devices like routers and switches and wireless access points etc you've got pulldown menus tools and the new toolbar is right up here at the top mostly I use the logical workspace and not the physical workspace so most of the time I'm in the logical workspace you know you can watch communication in real time or you can slow everything down and watch packets as they go from device to device in simulation mode so real time mode and simulation mode when you're in simulation mode or real time mode you also have this pop-out menu here which is it's easy to not notice so I'm going to point it out okay let's start off with a basic communication we need to pick our devices down here now the main devices are the networking devices if I click on this icon I can see my routers my switches my hubs wireless devices firewalls and cloud devices then you've got n devices like a PC laptop server printer IP phone etc you've got IOT devices like a microcontroller or single board computer and you've got your cables or your connections to connect the devices together so for a quick example I'm going to go to my end devices and I'll click on a PC and drop it here so click and click and then another PC and click and click and I want to connect them together so I could connect them directly together by going to connections and choosing a crossover cable which is right here but let's use an intermediary device so I'll click my network devices and then over to switches and then I have a choice of switches that I can choose from I'm gonna go for a basic or group switch 2960 Cisco switch right here and so there's my switch now we want to connect these devices together before I do that I'm going to zoom in on the workspace so I'm a little bit closer now okay now to connect these devices together I can use this tool right here which is the automatic connection choose connection type kind of wizard or I can choose which cable so a PC to connect to the switch I'm going to click on a straight-through Ethernet cable I'll click on the PC and then I can choose between rs-232 serial port nope USB USB or fast ethernet that's the port that we use for an Ethernet cable Fast Ethernet 0 so I'll click there and then drag over to the switch when I get to the switch I can hover over and see all of the ports on the switch but what I'll do is I'll just click on this switch and then I can see what we have here so the switch has a console port for a console connection serial connection I've got fast ethernet ports here one through 24 and two gigabit ethernet ports so this is it mostly a fast ethernet switch it's kind of an old standby switch that we use in the Cisco Networking Academy so I'll just choose one of these ports let's say Fast Ethernet port 10 so the interface is up with the green up arrow here this interface is coming up it's orange right now when it gets to green the switch port will be in forwarding mode so that'll take a couple of seconds here then I'll grab another cable this time I'll start off by clicking on the switch I'll choose a port and click and then drag over to the other PC over here and click and click so now I'm connected now these ports are not up yet oh there one went up and this one will go up in a second so I can fast forward time down here by clicking this button to fast forward time if you don't want to wait so to communicate from this PC to this PC we need to configure these pcs to configure a PC or a switch all you have to do is click on the PC and you have let's see here five tabs physical config guest top programming and attributes so on the PC you're mostly going to be using the desktop tab where you have desktop programs like a web browser a command prompt you have a special IP configuration tool this would be like network connections and windows so I'll go to network connections and I'll give myself a static IP address 192.168.0 will say dot five and then I'll click here and put a subnet mask 255.255.255.0 and now I'm done I could put a default gateway if we had a router and I could put a DNS server if we had a DNS server but we don't have one right now so I'll just leave it as is and I'll close that tool then I can use these other tools here you can see there's a bunch of tools to choose from all right I'll close this window and I'll go over to the other PC and I'll configure it likewise so we've got the physical connections we've got the config window there's the desktop IP configuration and will similarly give ourselves and IP address so this one will be 192.168.0.1 and the subnet mask and we're done now I don't need to configure a switch because with a Cisco switch their plug-and-play ready to go as soon as you plug in the switch and turn it on which it's on by default it's ready to go however you can see here if I click on it I see the physical representation of the switch here with the ports and this is way it looks and I've got a config window which we usually don't use because it's kind of like a cheat so we use usually the command-line interface to do most of our configurations so the text is a little small so I always encourage my students to go to options preferences and then font and then I can go to the command line interface setting and I can increase the font size so that it's easier to see when I'm working on the switch now in the command line interface if I'm gonna configure the switch I can see the the fonts a little bit bigger but we don't have to configure the switch so I'll just close that window and now we want to see a communication from this PC to this PC so I'll open up PC one and a command prompt and I'll issue a ping ping space 192.168.0 not 10 I'll hit enter and you can see I'm getting a reply from that device so there we are we have a communication from this end to this end and back again now if I want to do that really quickly and watch a ping go from this side to this side I can just click right here in the under simple PDU and then click here and then click here and the PDU is executed from here to here a ping is executed from here to here and down here in this window I see that it's successful if I want to watch that execution I can go to simulation mode and I can hit play and there goes the ping over threw the switch and we'll see here keep going there it goes and back again and I can see the packets as they travel across and that's in simulation mode alright I'll go back to real-time mode and I'll delete that let's switch this PC out or let's add another end device this time I'll add a server and set up a client-server relationship this server desktop IP configuration will give it the address 192.168.0.0 to five 5.25 5.25 5.0 notice the server which once again is right here under end devices located right here the server has services a services tab and these are some of the servers that it runs it has an HTTP server a dhcp server dhcp version 60 ftp dns syslog Triple A Network Time Protocol email server FTP server and so on and so forth so under HTTP server we can see there it is it's on HTTP is also on and then it has a web page index.html which you can edit and you can change instead of saying hello world dot let's see here instead of saying welcome to Cisco packet tracer I'll say welcome to Dan's courses or welcome to the network all right and save okay so and then file manager so there it is so there's the server it's on so if we wanted to see that web page all I've got to do is go to cables here connections I'll get Ethernet cable click and then click on Fast Ethernet 0 over to the switch this time we'll put in a Gigabit Ethernet port now the port is listening and learning and then forwarding so I'll do fast-forward to bring it up quickly and then I'll open up the PC open up the web browser put in the URL into the address bar 192.168.0.1 go and there it is there's the web page and it says right here welcome to the network so I was able to edit the homepage on the server so you can set up all kinds of client-server relationships you can set up connected local area networks you can set up routers that connect to other networks you can implement all kinds of routing protocols you can simulate or emulate the WAM and connections let's say across the internet emulate those types of connections you can use serial connections emulate DSL connections cable connections you name it but this is a perfect tool for learning about networking in kind of a simple easy to learn environment
