Our Guest access system seems to be having problems with DHCP. It seems to take a while to deliver an IP address making the client device show the "limited or no connectivity" message, which of course makes the users complain. On one occassion I have seen my own client eventually picking up an address even after the limited connectivity message appeared. On another I saw the debug showing "Dhcp request for autoconfig address", which I suspect is a symptom of the problem.
Our Anchor Controller is the DHCP server and is a 4402 running 22.214.171.124 - I've attached some DHCP packet debug but I'm not sure if it is of any help.
Any suggestions re what I can do to fault find or any other info that would help you help me?
I assume you are getting the right IP.. however we do have a bug which is active on the version that you are running 7.0.98 , here is the bug id..
Just for the testing purpose move the DHCP server to any layer 3 device and see if that helps or open up a TAC case and we will help you providing the engineering special image which resolves this issue.. and also, run the "Debug client and see in what stae the client is in and try to oing the Client acquired IP fro mthe Default gateway or from the controller and let me know..
lemme know if this answered your question..
