How to use switch in gns3 | switching labs in gns3 1.1

How to run a switch in Gns3:

In this article I will show you how to use Cisco switch in Gns3 1.1 and Gns3 0.8 virtualbox edition. You can perform switching functionality on GNS3 simply by using NM-16ESW module. This module is normally available or work with Cisco 3600 & 3700 series. Using NM-16ESW you can configure switching protocols like VLAN, STP, VTP on gns3 ect. 

Cisco Commands For Beginners

How to use Switch in Gns3 1.1:


Open Edit \ Preferences\ dynamips\IOS Router & click on new button.

Browse the Cisco 3600 & 3700 series image and click next.

Type it’s name and set a suitable RAM for it.


The next step is most important one, where you need to define NM-16ESW, you can choose it from drop down menu.

In next step, set the idle PC value for your router and finish this wizard.

After this you will find your router with switching functionality in Gns3 device menu.

You can drag it to gns3 stag and connect it via NM-16ESW module with other devices and you can try some switching commands that are mention at the end of this post.


How to use Switch in gns3 0.8 virtualbox edition:

  • First open the "Symbol Manger" from Edit tab.
  • Add a ethernet_switch from  available symbol to customize nodes. Type a name for switch and in Type field assign the Cisco router IOS to switch, in my case i select the  c3600 series and i have used IOS c3640-jk9o3s-mz.124-16a (33MB). You can download switch IOS for GNS3 from this link.

  • Click on apply and then on ok button.
  • Now you can find a new switch in nodes types.


  • Now drag this switch on stage and click on configuration and add  NM-16ESW module from slot tap.

  • click on OK you may received a message "You must use 'manual mode' to connect a link with a NM-16ESW module". Therefore use the manual method to configure this.

How to add switch image in GNS3 1.1

For gns3 1.1 open the edit\preferences, then explore the dynamips tab and click on "ios routers". now click on new and browse the above downloaded image, click next. 

Type name for router and click next. Now from slots tab choose the NM-16ESW for switching function and click finish.


Switching labs in gns3 

Now for test i shall configure two vlan on switch. For Vlan configuration you can use the following commands.
vlan database
vlan 10
vlan 20

  • Start your switch and try these commands also can see in screen-shot for vlan 10, 20.

For complete switching labs visit following posts of blog.   

1. Switch virtual interface SVI configuration on gns3 
2. Inter VLAN on gns3 
3. Hot Standby Router Protocol configuration on GNS3

    1. use the interfaces of fa1/0 ,fa1/1,fa1/2 .....etc

      instead of interface fa0/0 or fa0/1

      Delete
    2. Interface fa0/0 and fa0/1 are router interfaces. The Switch interfaces start from fa1/0.

  48. Hey thanks. Nice info. But what do I have to do to run vtp commands on this newly created switch. When I tried it in global mode, it asked me to create a file in which it will store the vtp database. I gave it the name : "vtp.dat". But then I couldn't do anything with that file or with any other vtp command. Any ideas?

    ReplyDelete
  49. I entered switchport mode access but it doesn't show up in the running config. Cant seem to figure out why... another site suggested that entering the commands in a specific order would make it work right but. I appreciate GNS3 but I wish I could just rent some real lab equipment for about three months..

    Unfortunately, GNS3 doesn't seem to be real tolerate of errors, once I write to the vlan.dat file when using these switch modules; so I have scrap the whole topology and start over just to test that theory... extra practice I suppose...

    Sw1Pod1#show run | section interface FastEthernet0/2

  72. hi!. please i set up my vlan using the vlan database command on a 3600 switch, and after setting the vlans, i proceeded to the global config mode to assign switchports to the vlans and also confirmed that the switchports have been assigned to the respective vlans using the 'sh vlan-switch brief' command. The issue i'm having is that after saving with the 'copy run start' and then restart the switch, and do the same 'sh vlan-switch brief' , all the initially assigned port would go to the default vlan (vlan 1). That is, there would be no more switchports assigned to the initially configured vlans.
    please, any form of assistance with this issue is welcome. my email address is bakaretemiloluwa@yahoo.com
