Hello everyone! I'm a networking student preparing to refresh my VLAN and trunk configurations. Right now I have a 3750X as my core device and a 3750G for hosting vSphere traffic. Only one VLAN seems to be active anymore, and the switches aren't configured to trunk. *Extra point*, I might need to reset the switches—I can access the WebUI but the CLI is refusing authentication. My current VLAN layout looks like this: VLAN 10 (10.1.8.0/24) for CoreLAN+WiFi, VLAN 20 (10.1.9.0/25) for Active Directory Lab with active clients, VLAN 30 (10.1.9.129/28) for Guest WiFi (captive portal + WPA2), VLAN 40 (10.1.9.145/29) for DMZ, and VLAN 50 (10.1.3.0/24) for vSphere and JumpServer traffic (only on the 3750G). These ranges are subject to change, but in the AD lab we need a /24. It seems the only working WiFi VLAN is VLAN 10. The VLANs 20 and 30 aren't functioning as before. My APs are connected to Gi 0/1/2, 0/1/4, and 0/1/6, while the trunk port from my firewall is Gi 0/1/1. The WiFi SSIDs don’t match real ones—secure VLAN 10 AD Lab, Guest VLAN 20, VLAN 30. I’m unsure how to set this up properly with the right native VLAN and trunks. Thanks for your help!
