If you have a Cisco 1000 series LAP in a network, which runs WLC versions 18.104.22.168, the 1000 series LAP does not join the controller and you see this trap message You could also try Option 43 on your DHCP pool for the APs but since you are using DNS I don't think that this is necessary. 0 Sonora get frequency Display the radio frequency (MHz). Management IP addresses of controllers the LAP remembers previously A Layer 3 broadcast on the subnet Over the air provisioning Statically configured information From this list, the easiest method to use have a peek here
If your network is live, make sure that you understand the potential impact of any command. This is known as Layer 2 LWAPP mode. Note:Some lines of the output has been moved to the second line due to space constraints. Sunday, August 9, 2009 Configure your LWAPP AP from the AP CLI I had this case a couple of times and thought it might be useful for all of us...
I tried to reboot the AP couple of times already but to no avail I still can't get to the CLI prompt of the AP. Open System Authentication (Response) 3.

If two controllers have the same excess capacity, then send the join request to the first controller that responded to the discovery request with a discovery response. Check This Out In Layer 2 mode, the LAPs are required to be on the same subnet as the management interface and the Layer 3 mode AP-manager interface is not present on the controller.

Check whether the Accept Self Signed Certificate check box is enabled. The debug pm pki enable command will also display the AP hash key during the join process if the AP has a self-signed certificate (SSC) created by the LWAPP conversion program.

The reason the controller needs an IP address on each subnet is so it can fill in the DHCP gateway address in the DHCP request.

The reason it does this is because when Windows roams between APs, the first thing it does is try to contact the DHCP server and renew the address. The more you practice, the easier the debugs are to perform and read. get authentication Display the authentication type. get association Display the association table.
