Hello All,
We have a Cisco infrastructure with several controllers on our network.
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;

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.
