WLC with AP's and Layer 3 switch acting as a dhcp pool/server(?)

[Consolacion]

so as the title suggests, ive been trying many times and configuring to make the wlc work without an external dhcp server. 

image below is the topology of what ive been working on

so i have 4 vlans for each switches, the layer 3 switch on the left serves as the dhcp pool/server, and the other is relay. and after all that's done, computer and ap's can get ip addresses, but the problem is when i go in the gui of wlc and go to wireless, there are no ap's listed on it

If the AP is getting IP address but not join the WLC, it might be connectivity issue.

When creating DHCP scope in cisco devices, always use excluded-address to avoid conflict

ip dhcp excluded-address 192.168.0.1 192.168.0.15

ip dhcp excluded-address 192.168.4.1 192.168.4.15

ip dhcp excluded-address 192.168.8.1 192.168.8.15

ip dhcp excluded-address 192.168.12.1 192.168.12.15

In order to the AP to discovery the WLC being in a different vlan, you need to add the option 43 to the DHCP scope of that vlan. Repeat the below configuration to other vlan you want to put APs.

!

ip dhcp pool VLAN30

network 192.168.8.0 255.255.252.0

default-router 192.168.8.1

option 43 ip 192.168.0.3
