Hi Carl. How have you been? Awesome, good to hear. VLANs? Yeah, I can help you with that. Your network is like a field of sheep and a VLAN is like having a Border Collie that knows to pick out and gather certain sheep together. Add another sheep and the Border Collie looks at a tag on that sheep and figures out which group it goes into. Why would you do that? Well, maybe some sheep have great wool or know how to make a call on a VoIP phone. Others are more tasty and should only talk to file servers. Who knows, but the tag defines the group and the dog puts them where they belong and can't escape. No mixing! We good? Excellent. You buy.
