Accessing Cisco Modeling Labs (CML) for Free

[Music] hey welcome back to the channel everybody this is Kevin and in this week's video we want to take a look at how you can get free access to Cisco's newest network emulator it's sort of the evolution of viral some people call it viral 2.0 but it's called CML cisco modeling labs personal version now what I do is I paid the $199 yearly licensing fee so I can run it on one of my local machines and I can access it whenever I want to I can have sessions as long as I want but if you don't want to pay the $199 the great folks over at Cisco dev net have made it available to you for free what you can do is go over to the Cisco dev net sandboxes we're gonna do in this video and we can reserve a block of time as long as four hours at a time where you can get access to CML personal version and you can set up your own topologies it's a great way to study it's a great way to to lab out concepts now if you enjoyed this video please do me a favor click like on this video and subscribe so you don't miss any of our weekly content now let's take a look at how we can connect for free to cisco modeling labs over at the cisco dev net sandbox I'm sitting over at the Cisco Devon at sandbox now and the way you can get here I've created a shortcut for you we can go to kW train com slash sandbox and you'll be prompted to log in and if you don't have a login you can create a free login but once you get logged in you're gonna see a screen much like this and I say much like this because the fantastic folks over at Cisco dev net they're continually iterating and adding things to what's available in the sandbox so this might look a bit different when you watch it but what I want to do is I want to search for Cisco modeling labs now at the time of this recording they have both CML personal and enterprise versions available I just want to use the personal version so in my browser I'm gonna do a find and I'm gonna look for the word modeling and I find this lab that says Cisco modeling labs and I need to reserve it so let's say I want to reserve it and we can reserve it for up to four hours at a time notice it's two hours by default but I and chains that if I want to and I can bump that up to as long as four hours notice that is the maximum and I'm gonna start right now so let's say Reserve and it's gonna take a bit of time to do the reservation but we have some work to do while everything is being set up notice we're in setup mode right now and we're told that it could take about 10 minutes or so to get everything set up one thing we need to do is to get secure access into the sandbox in other words VPN access if you go to the VPN access tab notice that there is a link to download Cisco's anyconnect VPN client software if you don't have that you'll want to go ahead and download that and there are instructions for getting it set up on your particular operating system I'm personally running on Mac OS and I've already got Cisco anyconnect set up and I'm gonna be either emailed my credentials or if you didn't say you want to get emailed at your credentials when the lab is set up you can click on this output button up at the top which is what I typically do so I don't have to bounce over to my email I'll click on output and once it has everything set up and it has my credentials ready they'll be listed here and then I'll open up my cisco anyconnect VPN software and using those credentials I'll get logged in and this is going to take a few more minutes right now it's estimating eight minutes to completion so after this is set up and after my credentials are displayed here in this window I'm going to resume the video and then we're gonna connect using the ne Connect software and we're going to build our own topology using Cisco modeling labs I'll see you back in a moment as soon as this setup is complete well good news the setup has completed so we're ready to connect and I'm given my username and password and if we scroll down just a bit we'll see our access credentials I'm gonna copy the VPN network name bring up our ne Connect software we'll say that is our destination we want to connect for the password I'll type that in say okay and we are connected excellent now in order to get to the CML screen I can go to this link so click on that it's going to open up in a separate browser tab and what is my username my username is developer I'll copy and paste that and my password is Cisco one-two-three-four-five with some creative capitalization and numbering I'll paste that in and we'll say login and just like that we're in Cisco modeling labs and they give us a lab by default that we can play with pretty nice topology and if you want to see details on that topology just scroll down here and here is that topology but the point of this video is I wanted to show you how to go out here and set up your own topology for laughing things up and studying for your exams so what I'm gonna do I'm gonna go to lab manager and I'm gonna turn this off it's taking up 14 of my 20 nodes right now and I want to create my own topology so I'm gonna say stop lab and you'll see this number 14 count all the way down and we won't have anything started and what I want to do is I want to add our own lab I'm going to say add lab and I'll put in a name of demo really creative and if I go into this demo lab then I can drag-and-drop devices over into this pane and I want to make a really simple topology let's get a couple of Cisco IOS virtual routers and we'll get an unmanaged switch to sit in the middle so that doesn't take up a resource and here's the way we can get things connected let me zoom in just a bit here so you can see it better if I hover over this router notice the little link icon here if I click and hold that I can drag a link over to the Sun manage switch and then it says what ports do you want to use well on that router I'm going to say Gigabit Ethernet 0/0 and I'll just use the first of it will switch for it and for my router on the right I'll do the same thing and say I want to use Gigabit Ethernet 0/0 connecting to port 1 on the switch and I might want to rename these so I'll click on this router and under no name I'm gonna say I want this to be known as r1 and for the switch I want it to be known as SW 1 and for this other router I want it to be known as r2 and now I want to start this topology up I'll go under simulate and I'll say Star lab and you'll see the little arrows indicating that these devices are booting up the unmanaged switch it went active fairly quickly we see that indicated with the green dot and when we get green dots on our routers we know that we can connect to them as well and by the way when we connect to them we can use the console that is built into CML and to do that for example our to see this little console icon if I click that I can open a console down at the bottom I can resize this so I have some more real estate but I can connect to router r2 after it boots up and do my configuration in that pain now in this version of CML there's not a tabbed interface where we can just have tabs for each of our devices that's coming in an upcoming release I'm told but for now we were just gonna have to go to one device at a time if we use this built-in console and we see things booting up there now let me show you what I prefer to do though what I would prefer to do is go to my own terminal emulator that supports a secure shell that does have a tabbed interface and you might have your own favorite terminal emulator I'm just going to use the terminal program that comes built-in to Mac OS because it makes a great secure shell client and it can have tabbed interfaces so let's go back to our definite sandbox and I want to see where I'm secure shelling it's gonna be this IP address let's go to my terminal and I'll say SSH and I want to go to developer at that address and what is the password copy and paste the password press ENTER and now I'm connected to CML via this secure shell connection and I can say the list and that's gonna list out my nodes and right now I've got r1 and r2 and there's a lab ID because I can have multiple labs running at once as long as I don't exceed 20 nodes and I've got a node ID and the lines the zero indicates the console port and the one indicates the auxilary port so on a managed switch you would see just a zero because the switch doesn't have an auxilary port let's say I want to connect to r1 here's how we do that I would say open forward slash and I'm gonna copy and paste the lab ID Florence slash and for r1 that's gonna be node in zero slash zero and that's the console so again here's the lab here's the node here's the line on that node I'll press ENTER and what I like to enter the configuration dialog no I would not that'll start booting up all it's booting up I want to create another tab and in this other tab I'm gonna go to this very same secure shell connection now we're in I'll say list and I'll open up in another tab r2 so I'll say open forward slash forward slash and one port slash zero and this is my r2 connection no I would not like to enter the configuration dialog and here on r1 let's just do a really basic setup to make sure we have connectivity I want to say the hostname is r1 I like to do a no IP domain - look up so if I type something incorrect it's not going to try to resolve it with the DNS server it just knows that it was a typo let's go into my console zero line and I'm going to say logging synchronous so these syslog messages popping up on the screen they're not going to interrupt something that I'm topping and I usually set in a lab environment I usually set the exact timeout to 0 0 so it doesn't timeout so what I'll do is say interface gig zero size zero' IP address 10.1.1.1 with a 30 bit subnet mask no shutdown let's go over to r2 new IP domain - look up console zero exec timeout zero zero and logging synchronous just sort of a set of best practice commands I almost always give when setting up a new router let's go into interface gigabit 0/0 and we'll say it's IP address yes 10.1.1.1 subnet mask no shutdown let's see if we've got connectivity oh I'm neglected to change the router name let me do that really quick I'll say hostname r2 there we go can I do a can I do a ping to 10.1.1.1 which is our one it looks like we've got an issue so we get to a little bit of troubleshooting here let's do a show IP interface brief and I assign the IP address to the wrong interface that was my bad let's fix that I'll say interface gigabit 0/1 no IP address shutdown interface gigabit 0/0 IP address thirty bit subnet mask no shutdown now can I ping you 10.1.1.1 yes I can the first was an arc timeout so no concern there the subsequent pings will all work though so we've got connectivity now let's go back here and that was just a super simple look at how we can for free go lab something up using the cisco dev net sandbox CML and we could create some fairly advanced topologies like the one we see here so if you want to play with this one this is quite extensive but for now we'll wrap up this video and look at how to use cisco modeling labs for free thanks to the great folks over at cisco dev net and i'll see you in our next video [Music]
