Trunk port on IAP93 is not work with Cisco Catalyst 3750 & 2960

I have configuring 4 SSID on IAP93 includes IT, STAFF, MGMT and GUEST each SSID map to VLAN follwing below

- IT SSID Assign VLAN 5 Network 192.168.0.0/24, SSID TYPE = Employee ---> Not working Client do not get IP Address from DHCP Server
- STAFF Assign VLAN 6 Network 192.168.1.0/24, SSID TYPE = Employee --> Not working Client do not get IP Address from DHCP Server

- MGMT Assign VLAN 7 Network 192.168.2.0/24, SSID TYPE = Employee --> Not working Client do not get IP Address from DHCP Server

- GUEST Assign VLAN 8 Network 192.168.3.0/24, SSID TYPE = Guest --> Wroking Cleint can get IP address from DHCP Server

Remark: I have testing my notebook connect LAN port direct to Cisco Catalyst 3750 & 2960 Switch to VLAN 5, 6, 7 and 8 can get IP Address from DHCP Server

I don't see anything attached. If you configure a WLAN in the IAP to be anything besides the "Default" VLAN, it will pass the traffic on that port and tag it with that VLAN. On the switch side, it needs to be configured like a trunk and it needs to allow all of the VLANs that you want to pass traffic for.'

The cisco switch config should look like this:

interface fastethernet 1/0
switchport mode trunk
switchport trunk native vlan 1
switchport trunk allowed vlan 1-10
