I'm trying to use the internal DHCP-server on a 4402 WLC v.7 for air-lap 1141n. But the WLC log says:

*DHCP Proxy DTL  Recv Task: Jan 18 14:51:58.591: c4:71:fe:34:14:c7 DHCP received op  BOOTREQUEST (1) (len 310,vlan 228, port 2, encap 0xec00)
*DHCP Proxy  DTL Recv Task: Jan 18 14:51:58.591: c4:71:fe:34:14:c7 DHCP dropping  packet from AP c4:71:fe:34:14:c7 received on port 2, vlan 228

Here are a screenshot of the ap-manager interface.

Primary DHCP server is set to management interface (

I'm not sure how the Internal DHCP server and ap-manager works togheter, is there a way to connect the DHCP scope to ap-manager?



I have this problem too.

The DHCP server information should be filled under MANAGEMENT interfcae DHCP server as well..

that is..

instead of configuring the DHCP server ip on AP-manager, do it on MANAGEMENT interface... check this DOC..

that is..


Lemme  know after making this changes, this will help you!! and keep in mind,  DHCP AP to get an IP from the WLC = Same VLAN for management and  AP-manager and AP VLAN.

lemme know if this answered your question..
