thank you, keep on doing what you do best

When you try to add a layer 2 switch via an appliance from GNS3 you get the KVM not supported issue. Adding it this way thru QEMU under preferences was mindless. Thanks for the easy factor. Routing newbie and I appreciate the good videos.

Hi, I am having issues. I have installed the L2 & L3 but I continue to get Duplex Mismatch. It is auto negotiated. The switch is not full-duplex and the router is. the media type is rj45. (not sure if this has anything to do with it.) Please advise. Thank You.

[adrianord]

When installing on MAC, I'm not able to see the switch on installed appliances. Any advice?

[ajaykhanna]

Hey How many GIG port we can configure in this L2 Switch ?? I tried adding 10 but the switch was not booting up it got in some kind of loop. Please help!

[SeraphimTech_io]

thanks a lot for tutorial and iosv2 file....
if somebody has issue search in google
I had HAXM issue and search it in google and solved my problem...
never give up

[Ravindunethsara]

HI i can only add 3 network adaptors. is there any way to add more?

[numansmail]

Hello There, I followed your video and it installed OK BUT the IOS doesn't load when I telnet in can you assist I am using GNS3 2.1.21

[MsWorlder]

Hello, Thanks for this easy step switch build on GNS3, I just have a doubt when writing the configuration after the reboot of the switch it goes back to default configuration as if I did nothing any solution please for this ?

[Snowflake]

Hi, thx for the video.
But I have a problem after installing Vios-2 which is when I run the MSW then I issue for example #show int g0/0 then in the output it say unknown Media Type which in the result of that SW can't do the negotiation for speed and duplex and reads all the interfaces as shared type (Like a hub interface) in the output of # show spanning-tree .
I googled a lot about it but I couldn't find a solution to that, I also used different versions of GNS3 like 1.5.3 and 2 but the same issue.
if you could guide me through that it would be great.

If you need more intrefaces, you have to change the memory. 256MB = 4 intrefaces, 512MB= 8 interfaces ...etc

[ajithm]

I done all the things as you say but.that layer 2 switch was not shows 127.0.0.0 retrying...but it wasn't working why?

[henryluu]

Hey bro, Can you help me?
I have install IOU L2 SW in GNS3 2.0.3, I can not ping through IOU sw.
Example:
Simple topology => Router - IOU (L2) SW - Router:
+ I config interface in the same subnet but I can not ping each router another, but I replace the IOU sw by ethernet SW in GNS, each router can ping with another.
+ I have try many version of L2 IOS but it not work and config no ip routing, no shut interface, no shut interface vlan 1 but is no work to.

Tks you!

[mariamhachem]

Hello, what can I do if I want the switch to have fast ethernet ports?

[secndlife]

i got prompted with telnet and vnc, whcih one should i select

[super-super-]

What's the difference between this QEMU image and IOU images?
