Configuration on Cisco C3750 for ZF7982

Question

I has problem on getting the DHCP from the AP for both users vlan on Cisco switch configuration. The AP manage to discover the ZD and AP are able distribute the SSID. The question is i'm not able to get any IP address when connected to both SSID.

From the Cisco configuration when i change to 'switchport mode access', AP will lost connection to ZD.

i have 3 VLANs:

80 - MANAGEMENT

81 - WIRELESS_STAFF

91 - WIRELESS_GUEST

Cisco IOS Software, C3750 Software (C3750-IPBASEK9-M), Version 12.2(53)SE2, RELEASE SOFTWARE (fc3))

!

interface GigabitEthernet5/0/12

description Connect_to_PutraWiFi_AP

switchport access vlan 80

switchport trunk encapsulation dot1q

switchport trunk native vlan 80

switchport trunk allowed vlan 81,91

switchport mode access

no cdp enable

spanning-tree portfast

!

Could someone help me to check whether the configuration are correct or I'm miss some step.

switchport trunk native VLAN 80       # will untag VLAN 80

switchport trunk allowed vlan 80,81,91       # but you still need to allow VLAN 80 too
