I want to establish a few VLANs on my home network. Network diagram below. Though I thought I was comfortable with setting up VLANs my trial failed. I've watched every video available on YT, but now realizing it's true how different vendors act a little differently. For example, Ruckus/Brocade has no mention of PVID or trunk/access. Just tagged/untagged.

What I want:

• VLAN 1 for default/management
• VLAN 2 for IOT
• VLAN 3 for guests over wifi
• Want to be able to not have to designate single physical ports for each since switches are difficult to access. Want to be able to plug any line into any port and have them work. Not worried about physical port security or ensuring only certain devices can use certain ports. All guest traffic will come from Wifi.

What I tried:

• on "core" 7150 switch
  • VLAN 2 tag 1/1/1 to 1/1/12
  • VLAN 3 tag 1/1/1 to 1/1/12
  • VLAN 1 untagged 1/1/1 to 1/1/12 (says already defaulted)
• on first "edge" 6430
  • same things

Then, I had no access to anything. So reset 6430 and everything works again. But what am I doing wrong with planning this?
