Please post any responses you get offline. I have the same problem, and others will. The solution from Cisco was to move the DHCP server to the same subnet as the controllers (not possible for me).

We run a WPA-TKIP environment with EAP-TTLS auth. The users are able to log into the network. However they never get an IP address. This kind of thing never happened to us before, while running the system for over three years. This is a sample dpug output from the controller; Has anyone seen anything like this; Fri Sep 19 10:49:09 2008: 00:40:96:a9:0b:96 DHCP REQUEST for autoconfig address - clearing server ip 0.0.0.0 (old IP 0.0.0.0) Fri Sep 19 10:49:09 2008: 00:40:96:a9:0b:96 DHCP selecting relay 1 - control block settings: dhcpServer: 0.0.0.0, dhcpNetmask: 0.0.0.0, dhcpGateway: 0.0.0.0, dhcpRelay: 10.10.10.16 VLAN: 252 Fri Sep 19 10:49:09 2008: 00:40:96:a9:0b:96 DHCP selected relay 1 - 10.10.10.1 (local address 10.10.10.16, gateway 10.10.10.1, VLAN 252, port 2) Fri Sep 19 10:49:09 2008: 00:40:96:a9:0b:96 DHCP transmitting DHCP DISCOVER (1) Fri Sep 19 10:49:09 2008: 00:40:96:a9:0b:96 DHCP op: BOOTREQUEST, htype: Ethernet, hlen: 6, hops: 1 Fri Sep 19 10:49:09 2008: 00:40:96:a9:0b:96 DHCP xid: 0x11291079 (287903865), secs: 6912, flags: 8000 Fri Sep 19 10:49:09 2008: 00:40:96:a9:0b:96 DHCP chaddr: 00:40:96:a9:0b:96 Fri Sep 19 10:49:09 2008: 00:40:96:a9:0b:96 DHCP ciaddr: 0.0.0.0, yiaddr: 0.0.0.0 Fri Sep 19 10:49:09 2008: 00:40:96:a9:0b:96 DHCP siaddr: 0.0.0.0, giaddr: 10.10.10.16 Fri Sep 19 10:49:09 2008: 00:40:96:a9:0b:96 DHCP requested ip: 169.254.49.163 Fri Sep 19 10:49:09 2008: 00:40:96:a9:0b:96 DHCP sending REQUEST to 10.10.10.1 (len 350, port 2, vlan 252) Fri Sep 19 10:49:09 2008: 00:40:96:a9:0b:96 DHCP selecting relay 2 - control block settings: dhcpServer: 0.0.0.0, dhcpNetmask: 0.0.0.0, dhcpGateway: 0.0.0.0, dhcpRelay: 10.10.10.16 VLAN: 252 Fri Sep 19 10:49:09 2008: 00:40:96:a9:0b:96 DHCP selected relay 2 - NONE Now what I do see, is that the client is trying to request a 169.254.49.163 address. The router should still respond with a proper IP address regardless of which one the client is asking for. Any help on this matter would be greatly appreciated. Thanks.
