GNS3 stands for Graphical Network Simulator 3, and it is exactly what the name says: a software to simulate networks. Introducing GNS3īefore we start the GNS3 Tutorial, we should explain what is GNS3. Again, If you want to test a scenario before implementing it at work, GNS3 is the product for you. If you want to study CCNP without buying expensive hardware, you are in the right place. So, if you can’t stand the “Command not implemented in this version of Packet Tracer” message, you are in the right place.
We will give you the tools to train for CCNP and CCIE!
With this GNS3 Tutorial, we will teach you how to create a virtual data center on your laptop. Today, we take practice to the next level.
If you have followed the Free CCNA course, you know that you can start practicing with Packet Tracer. Practice with you the confidence you need to avoid that. In your career, you will face many moments when things aren’t working the way they should. Learning the concepts of networking is crucial, but still worthless with no practice. In this article, we examined the GNS3 Layer 3 Switch settings, the most popular network simulator program used to prepare for Cisco exams.If you are a network engineer (or starting to be one), you know the importance of practice. You can watch the video below to use Switch on GNS3 and also subscribe to our YouTube channel to support us!

Please update the IOS to enable the "macro" command! Warning: You are using an old IOS image for this router.
To view existing vlans use the command "show vlan-switch brief" To create vlans use the command "vlan database" from exec modeĪfter creating all desired vlans use "exit" to apply the config It has been preconfigured with hard coded speed and duplex This is a normal Router with a SW module inside (NM-16ESW) You can see that pinging between VPCS is successful.ĭescription *** Unused for Layer2 EtherSwitch *** ESW1# conf tĮSW1(config-if)#ip address 192.168.10.1 255.255.255.0Ĭonfigure the VPCS and then ping the VLAN1 interface to test the connection as follows. Now, to test the Switch, execute the show vlan-switch command in the CLI command interface.Ĭonfigure the switch by executing the following commands. Wait while calculating the Idle-PC value.Īfter determining the optimal Idle-PC value for IOS, click OK to continue.Īs you can see in the image below, the Layer 3 Switch (EtherSwitch Router) has added successfully.ĭrag and drop the Switch to the GNS3 workspace.Ĭreate a topology as follows and double click on 元 Switch. In the Network Adapters window, select the NM-16ESW interface in Slot 0 and continue to the next step.Ĭlick the Idle-PC Finder button to select the optimal value for your computer’s processor performance for Layer 3 Switch IOS. Leave the RAM value of Layer 3 Switch as default and click Next.
In this step, select “ This is an EthernetSwitch Router” and then click Next. The GNS3 program asks if you want to copy the IOS to the default image folder, click Yes.Īfter adding Switch IOS, click Next to continue. Select the IOS you downloaded from the above button and click the Open button. In the IOS Image window, select New Image, then click Browse. To add 元 Switch, click the New button in the IOS Router templates window. Previously we added L2 Switch from Qemu VMs. In the General Preferences window, click the IOS Routers tab.
