AP's config is irrelevant, because it will be erased when LWAPP image is installed (only static management IP address can be saved).


The switch ports that AP connects to will have to be configured in 'switchport mode access'. You can put it in any VLAN you want as long as it has reachability to the WLC's management/ap-manager interface IP addresses.


WLC's interface on the switch should be configured as "switchport mode trunk"

Ok, now I recall this past week attempting to do the LWAPP upgrade on the access points, and I kept getting an error similar to the documentation where it shows something was stoping the upgrade tool to access the APs.


The computer used was windows xp and it was connected directly with the same subnet configuration of the APs. So, connectivity was not an issue. It was like if something in the access point was stoping the Upgrade tool from making any changes.


I had followed the instructions creating a text file with the following information.


ap-ip-address,telnet-username,telnet-user-password,enable-password


10.2.1.2 (AP ip address),admin,password,password


How do I troubleshoot this?


The instructions on the paper says..

Upgrade Tool Window-Firewall or Access Control List with Internal TFTP Server

was it complaining about recovery image not being right? (use older recovery image)


was it complaining about tftp not being able to start? (make sure tftp is not already running on your machine)


did you enable telnet access on WLC? (by defaul it's SSH only)


can you telnet to AP from your machine with that admin, password, password?


telnet to AP, enable "term mon", and try upgrade tool, watch for any error messages in the logs on the AP


upgrade tool basically telnets to your AP in the background, does a bunch of commands, downloads the image, and reboots. it also telnets to the WLC to check few things.

if you are interested, here's a script of what upgrade tool does on the AP. I captured it with wireshark

Hoooooooo boy. This is going to be a looooooooong night. Please pass the grog.


I recommend that you spend time to get yourself acquainted with the Cisco Wireless LAN Controller Configuration Guide.


http://www.cisco.com/en/US/docs/wireless/controller/5.2/configuration/guide/Controller52CG.html


If you have been given the task of managing the WLN of your organization, this will give you a better understanding of what you will be dealing with and minimize the chances network outages.


Hope this helps.

Great News!


I finally got the Access Points working with my WLC.


The access points are showing on the WLC screen and obtaining their individual ip addresses.


Now, How do I ensure the wireless clients gets their ip address?


The wireless SSID is been advertised, but, the clients can not get an ip address.


I know when the AP were autonoumus, I could setup a VLAN for the clients. I do not know how to setup the same VLANs for the LWAPP access points.


Thanks

It is no use asking forum members all the questions when it can easily be found if you spend a little bit of time reading the documents.
