Cisco Ethernet Switch Ios For Gns3 Router

Posted on

This is post 3 of 3 in the series “GNS3”. Cisco switches in GNS3, the ultimate tutorial Learn how to add Cisco switches and L2 devices to your GNS3 topologyIn our last articles, we learned the beauty of GNS3 to create complex routing labs. However, networks are simply not complete without switches. By now, you should have a few routers (IOS images) on your GNS3 belt. Adding switches is not so easy, but it is definitely doable.

In this article, we are going to give you a step-by-step tutorial on how to add Cisco switches to your GNS3 topology. The GNS3 VMThe GNS3 Virtual Machine is simply a server packed in the form of a virtual machine. Its simple purpose is to run the emulation of your devices in a centralized point: this saves you a lot of resources. In fact, by adding routers with the traditional method of Dynamips, each router eats a lot of RAM and CPU. Well, not anymore with GNS3 VM. How does it work?The VM acts as a central point, and communicates with your PC through IP on a host-only adapter.

Your GNS3 GUI sends a request to the server, which elaborates them and returns replies. As simple as that. Both GNS3 and GNS3 VM run on your PC, but you interact with GNS3 which then interacts with the GNS3 VM. How can we benefit from this?Trust me, you are going to save tons of computational resources on this. However, this is not all: you add support for L2 devices.

Yes, this means you can have a manageable switch in your topology. Once you have this in place, you won’t be able go back to Dynamips anymore. Installing the GNS3 VM Getting the VMThe GNS3 VM is free, as GNS3. In fact, it was developed by the same team and you can download it for free from their. Ensure to download the VM with the same version of GNS3: in this example we are using 2.0.3, therefore the VM needs to be that version too.

The download link for the VM is quite small, as in the picture below. Click on the highlighted link to download the VM.At this point, the site will propose several options: VirtualBox, VMWare Workstation and VMWare ESXi. However, in our last article we have already used VirtualBox, since it is the only free option we have. Therefore, you can simply select VirtualBox. Since this tutorial will show you the steps to do that with VirtualBox, you need to have it installed. In case you haven’t, or you are confused about it, just check our latest article about.This download will give you a compressed file. You can simply un-zip it with our favourite tool (like 7zip), and you will find an OVA file in it.

The OVAOVA is a special file format that contains Virtual Appliances. Each file contains all the details for a virtual machine: its software, virtual disks and resource settings. It is like receiving a physical PC with all the needed software already on it. However, this is virtual: much simpler. If you installed VirtualBox correctly, your PC knows that it has to open OVA files with it. As a result, you will see an orange box icon next to the file. The Import Wizard.Here you can check all the settings, and eventually modify some.

However, the GNS3 VM was packed this way for a reason. Because of that, you don’t need to do anything special here: just click Import. The import will last a few seconds, then you will have to click on Finish. And this is it.

Now that we have the GNS3 VM, we need to associate it with GNS3. Setting-up GNS3 The Local ServerWith VirtualBox open, launch GNS3 as an administrator. When starting, GNS3 will raise a pop-up asking to configure a local server: today we are going to do it, and get rid of that pop-up forever.

In case your GNS3 doesn’t do that, don’t panic. Just navigate to the preference and find your way to Server and GNS3 VM. You will be able to follow this tutorial anyway.

The GNS3 Wizard appearing on start.Here, be sure that you have selected the first option: Run modern IOS, which should be the default. Then, click Next to move to the following step. At this point, the Wizard will ask you to configure a Local Server. Here, change the Host Binding to 127.0.0.1. This will ensure you will have GNS3 always working, even if you are offline. Click “next” and GNS3 will try connecting.In case you receive a failure message, navigate to the path specified in Server path and run gns3server.exe manually by double clicking on it. Then, click “next” again.

The GNS3 VMThe next point in the setup is finally the GNS3 VM. Here, you just have to select VirtualBox. GNS3 will automatically search in your list of Virtual Machines for the right one. In case it has trouble finding it, just hit “Refresh” and use the drop-down to select the GNS3 VM. Once finished, click “next”. The common DHCP error.If you see this error “GNS3VM: DHCP must be enabled on VirtualBox host-only network”, don’t worry.

You can continue the setup-with no problem. At this point you are going to have a recap window, where you can click Finish. Cisco IOS on Unix (IOU)IOS on Unix is what we are going to use our VM for. It is a reworked Cisco IOS that runs on top of Unix, as the name says.

As a result, we can efficiently run it on our normal CPU, without having to worry about ASIC emulation. In fact, IOU supports both L2 and L3 devices (including switches!). To install that, you need to have the Cisco IOU images: one for L2 and one for L3. This is copyrighted material, thus I can’t give it to you. If your company is entitled to that, just use it. In case it isn’t, the Internet is full of stuff, you can easily find it by googling.

Once you have the IOU image for L2 and L3, continue with the following steps. Installing IOUAs soon as you finish creating the GNS3 VM, the following window will appear. This is asking you to install a virtual router or appliance, and gives you the options to do that. Here, select IOU.In case this window doesn’t pop-up, don’t panic.

You can easily install IOU from Edit Preferences IOS on UNIX IOU devices. If that’s the case, navigate to this path and click New.A new window will appear, asking you what to do with the virtual router we are creating. However, the system will give us the only option to use the GNS3 VM, so we can only click Next.In the next tab, you will have to give the VM a name, select if that’s a L2 or L3 device, and load the image. Below, an example of configuration. Example configuration.Once you are happy with the settings, simply click Finish.

Repeat this step for the L3 machine, of course. If you did this process from Preferences, don’t forget to click Apply before clicking OK. Adding the IOU LicenseNow you need to add the license of your IOU images. If you got them online, chances are the images will come with a license. If not, the Internet is always your friend, you will probably be able to find even something to generate a license. To add the license, you need to navigate to Edit Preferences IOS on UNIX (not the devices’ section). Here you will have a big text box and a Browse button, which you should click.

Here, click Browse.Now, select the file containing your licenses, click Apply and then OK. The license will look something like that: licensegns3-vm=In case you got an old license for gns3-iouvm, simply rename that part to gns3-vm. If everything went the right way, you now can use IOU images to run L2 and L3 devices. With them, you will be able to do complex CCNP and CCIE labs, and boost your career. Try to drag into your project the IOU devices and see how they react, maybe when having multiple of them running.What are your thoughts about the GNS3 VM and IOU?

What labs are you going to build with them? Just let me know in the comments!

The Cisco enhanced EtherSwitch service modules connect to Cisco 2900 series and Cisco 3900 series routers through the service module console Gigabit Ethernet port to a serial interface on the router. This Gigabit Ethernet port gives the appearance of a Layer 3 port to the router.The Cisco enhanced EtherSwitch service modules also provide a physical Gigabit Ethernet serializer/deserializer integrated circuit transceiver High-Speed Intrachassis Module Interconnect (HIMI) interface. In the Cisco 2900 series and Cisco 3900 series routers, the HIMI link on the Cisco enhanced EtherSwitch service modules is connected to the router internal Gigabit Ethernet backplane. This link is used for interconnection between other interface cards or network modules attached to the router Gigabit Ethernet backplane bypassing the router host CPU, thus increasing CPU performance by decreasing CPU processing.To access the Cisco enhanced EtherSwitch service module, establish a session from the router over the serial interface to the Cisco enhanced EtherSwitch service module. To exchange and monitor control messages between the Cisco enhanced EtherSwitch service module and the router, a Router Blade Configuration Protocol (RBCP) stack operates concurrently on active IOS sessions running on both the router and the service module.Feature History for the Cisco Enhanced EtherSwitch Service Modules (SM-ES2-16-P, SM-ES3-16-P, SM-ES3G-16-P, SM-ES2-24, SM-ES2-24-P, SM-ES3-24-P, SM-ES3G-24-P, SM-D-ES2-48, SM-D-ES3-48-P, and SM-D-ES3G-48-P).

Access Cisco Feature Navigator at. You must have an account on Cisco.com. If you do not have an account or have forgotten your username or password, click Cancel at the login dialog box and follow the instructions that appear. Accessing the CLI Through a Console Connection or Through TelnetBefore you can access the Cisco enhanced EtherSwitch service module CLI, you must connect to the host router through the router console or through Telnet. Once you are connected to the router, you must configure an IP address on the Gigabit Ethernet interface connected to the Cisco enhanced EtherSwitch service module. Open a session to the Cisco enhanced EtherSwitch service module using the service-module gigabitethernet x/0 session command in privileged EXEC mode on the router.You can use one of these methods to establish a connection to the Cisco enhanced EtherSwitch service module:.

Connect to the router console using Telnet or Secure Shell (SSH) and open a session to the switch using the service-module gigabitethernet x/0 session command in privileged EXEC mode on the router. Use any Telnet TCP/IP or encrypted SSH package from a remote management station. The internal interface must have network connectivity with the Telnet or SSH client, and the internal interface must have an enable secret password configured.

After you connect through the CLI, a Telnet session, or an SSH session, the user EXEC prompt appears on the management station.The Cisco enhanced EtherSwitch service module or switch supports up to 5 simultaneous secure SSH sessions and up to 16 simultaneous Telnet sessions. Changes made by one Telnet user are reflected in all other Telnet sessions.You can use the following configuration examples to establish a connection:. To configure an IP address and subnet mask for Gigabit Ethernet interface (gigabitethernet 1/0) on the router, use the following command. Using Interface Configuration ModeYou can configure the individual Cisco enhanced EtherSwitch service module physical interfaces (ports) through the interface configuration mode on the CLI.

Type — Fast Ethernet (fastethernet or fa) for 10/100-Mbps Ethernet or Gigabit Ethernet (gigabitethernet or gi) for 10/100/1000-Mbps Ethernet ports. Module number — The module slot number on the Cisco enhanced EtherSwitch service module or switch (always 0 on the service module or switch). Port number—The interface number on the Cisco enhanced EtherSwitch service module or switch.

The port numbers always begin at 1, starting at the right when facing the front of the Cisco enhanced EtherSwitch service module, for example, gigabitethernet 0/1, gigabitethernet 0/2 with 0/1 on the top, 0/2 on the bottom, 0/3 on the top, 0/4 on the bottom and so on.You can identify physical interfaces by physically checking the interface location on theCisco enhanced EtherSwitch service module. You can also use the Cisco IOS show privileged EXEC commands to display information about a specific interface or all the interfaces on the Cisco switchingservice module.These are examples of specifying interfaces:. To specify Gigabit Ethernet port 4 on a standalone Cisco enhanced EtherSwitch service module, enter this command in global configuration mode.

Configuring the Cisco Enhanced EtherSwitch Service Module in the RouterThis section describes how to perform the initial configuration on the router with a Cisco enhanced EtherSwitch service module installed. This section also describes the initial configuration on the Cisco enhanced EtherSwitch service module itself. Once an IP address has been configured on the Gigabit Ethernet interface on the router (representing the Cisco enhanced EtherSwitch service module), you can open a console session to the Cisco enhanced EtherSwitch service module and configure its Fast Ethernet and Gigabit Ethernet interfaces for Layer 2 or Layer 3 functionality.Once the Cisco enhanced EtherSwitch service module interface has been configured and you boot up the service module image, you can switch back and forth between the router and the service module. The Cisco enhanced EtherSwitch service module software can be corrupted while upgrading the software, by downloading the wrong file to the Cisco enhanced EtherSwitch service module, and by deleting the image file. In all of these cases, the service module does not pass the power-on self-test (POST) and there is no connectivity.This procedure uses the Xmodem Protocol to recover from a corrupt or wrong image file. Many software packages support the Xmodem Protocol, and this procedure is largely dependent on the emulation software you are using.To start the Xmodem protocol process, issue the password reset command.

After you issue the password reset command, the following message appears. Recovering from a Lost or Forgotten PasswordThis section shows how to recover from a lost or forgotten password.The default configuration for the Cisco enhanced EtherSwitch service module allows an end user to recover from a lost password by entering a new password.During auto boot loader operation, you are not presented with the boot loader command-line prompt. You gain access to the boot loader command line if the switch is set to manually boot or, if an error occurs, the operating system (a corrupted Cisco IOS image) is loaded.

You can also access the boot loader if you have lost or forgotten the switch password. Note The default configuration for Cisco enhanced EtherSwitch service modules allows an end user to recover from a lost password. The password recovery disable feature allows the system administrator to protect access to the switch password by disabling part of this functionality and allowing the user to interrupt the boot process only by agreeing to set the system back to the default configuration. With password recovery disabled, the user can still interrupt the boot process and change the password, but the configuration file (config.text) and the VLAN database file (vlan.dat) are deleted.

Switch# copy running-config startup-configCopies the configuration from the running configuration file to the switch startup configuration file. This procedure is likely to leave your Cisco enhanced EtherSwitch service module virtual interface in a shut down state. You can see which interface is in this state by entering the show running-configuration privileged EXEC command. To reenable the interface, enter the interface vlan vlan-id global configuration command, and specify the VLAN ID of the shut down interface. With the Cisco enhanced EtherSwitch service module in interface configuration mode, enter the no shutdown command.Step 10reload. Switch# copy running-config startup-configCopies the configuration from the running configuration file to the switch startup configuration file.
