For example VLAN 5 is only for wireless access points, so every Switch I want to have an Access point on must have VLAN 5 defined on it and added to the interface. This also allows me to set up a test switch so I can test equipment at my desk, with the IP address it will have out in the field.  It's been running fine with this setup for years. 

Now there's a push from corporate to isolate the VLANs, one VLAN per switch, or a couple, but they can't be defined on any other access switches on the network. This is going to require a major undertaking by me to define new VLANs add them to the switches, set up, reserves / DHCP scopes and re-Ipaddress static / reserve devices with the new VLANs,  Does anyone know what the logic in this is?  Is this a more secure networking design?  My understanding if a loopback address is added, it can cause a VLAN spanning tree loop because the VLANs are located on so many switches.

I guess I'm not seeing the bigger picture here. What ever that looks like.
