Creating VLANS in a GNS3 Switch

djfunz

Hopefully, this will be helpful to some here. Some of the commands appear to be different for the NM-16ESW module than for a standard switch.

I've never done it in GNS3. I was thinking I had to use a real switch. Thanks for sharing!

I'd rather not get used to typing commands that aren't going to be switch commands.

You can do [basic] switching, but the switching isn't a "switch" CLI. Typing "vlan database" instead of "vlan [id-numnber]", and in the exec-mode instead of Global-Config mode, Respectively.

No question the real thing is better. I just personally can't afford real gear at the moment. For others in the same situation, GNS3 provides just about everything I'll need at the CCNA level. Port Security, VTP, VLAN and STP are also pretty well supported in Packet Tracer I believe.

Yes, Packet tracer has switching

Don't change the subject! GNS3 is where we were discussing!

Packet tracer is for alumni of cisco academy, and academy students and not everyone is an alumni.

It's expensive, im not going to say otherwise, i've yet to buy my first piece of lab equipment because I don't have the money. Im trying to hold off on buying equipment until I pass the NA exam. In this way I can justify the buying to the other half, instead of a washer and dryer. Ebay has been mentioned as a good place to buy, you can find deals - i've been watching. Im going to get switches first, then work my way to routers.

Honestly, you can get (3) 2950 switches on eBay for well under $100.

GNS3 is great but for practicing switching nothing beats the real thing.

How about two routers how much will that be?

Roguetadhg

depends on the model. 1720 are dirt cheap routers that'll give you hardware experience. They don't stack too well though. Under 50$ used easily on ebay.
