Vlan config

[Rookcr]

Good morning,

I would like to segment a test enviroment on my network. I have assigned a subnet and set my 2nd ethernet port on my router as the gateway. My question is how do I vlan through my multiple Cisco 2950 Switches to keep traffic seperate.

set up the vlan, assign the ipaddress and then assign the ports into the vlan.

If more than one vlan needs to pass between switches then an 802.1q trunk needs to be set up. Thsi tags the data on Egress from the port and is read at the far end on ingress.

I have done all of this and it works great. Much easier then I thought.

Please note that if you are running a multiple layer 2 switching environment, then you run the risk of a loop if you do not have Spanning tree enabled.

Create a Primary bridge with a low cost (something like 8192 - I think the default for Cisco switches is 32768 or something like that).

If you do not have lots of layer 2 switches then dont worry too much.
