DHCP relay agent on 1941w

I have a 1941W and an external DHCP server. Wireless clients should get their IPs the same way when they are wired. I have checked the documentation but no help. Someone share such a document or help on how it can be done.

So the interface in your router should look like this

interface Wlan-GigabitEthernet0/0
description CONNECTION_TO_AP
switchport trunk native vlan 100
switchport mode trunk
switchport trunk allowed vlan 1.100, 600
no ip address
spanning-tree portfast
