I have a simple non-VLAN'ed network. I'd like to create a VLAN to carry guest traffic only. Do I need to create 2 VLAN's? one for the guest network and one for the corporate network? Or do I just create a VLAN for the guest network and leave the corporate network "untagged"? All my switches are managed and we have a SonicWall router so everything is VLAN capable but it's never been setup.
I know I will need to create trunk ports between the switches and access ports for everything else. Am I on the right track?
