vlan IP i get from a AP

I am new to the company and I’m trying to figure out the infrastructure here. I am having hard time finding where my wireless IP is coming from.

I know it’s on VLAN 15. I looked on the core switch which is the vtp server. When I do show run, vlan 15 does not show up. When I do show vlan brief, vlan 15 shows as active. I cannot find anything associated on that switch with the subnet I received when logging into that wireless connection. How else could I get that IP or how can I pin point this? I went to gui of the AP and it’s clearly on vlan 15. When I do show vlan brief on thw switch the AP is connected to, the port does not belong to vlan 15.

In Aruba implementations, often the APs will tunnel on a single VLAN (like the default or a specified VLAN) back to the controller, where the other VLANs (such as vlan 15) will be reachable. This way, the DHCP packets in the tunnel and give the computer/AP the appropriate address. What kind of wireless gear do you have?

Well, there is no wireless controller, we have an ACS but did not see anything special there. I got an 1130 AP, I have a 3560 L3 core switch and 3560 server switches.

I also searched the entire workbook in excel which we have all the devices on and i did not find anything on the vlan 15 network address, the only thing i found was a ip route
