[c-nsp] Issues with Air Fortress and Aironet when trunking to the AP

[McLean Pickett]

Has anyone else out there seen issues with aironets and Air Fortress software when trunking to the AP?
 
If I do not create a trunk to the AP from my 3750 and do not associate my SSID with a VLAN then the client application is able to connect and authenticate to the Air Fortress gateway devices. If I setup a trunk to the AP and assoicate the SSID with a non-native vlan then traffic does not apprear to be bridged to the switch. I see no mac address table entries on that switchport for the non-native VLAN. The trunking configuration works fine if I remove the Air Fortress software.
 
While looking over sniffer traces I came across an Ethernet II protocol which is listed on Cisco's site as Aironet DDP that appears to be some sort of broadcast sourced from the wireless client. Can anyone tell me what DDP is?
 
Thanks,
McLean
