Cisco Wireless Lan Manager

Unanswered Question

I'm fairly new with getting cisco AP and 4400 working together.

I inherit a network of 100 cisco access points and a wireless lan manager. The network needs to be updated with a new subnet. However, each AP has a static ip address.

Can you provide any suggestions as far:

1) how to change all the APs to new subnet address

2) how to configure the wireless lan manager to work with the APs?


I have this problem too.

What do you mean by Cisco Wireless Lan Manager? Wireless Control System (WCS) ? Wireless Lan Control System (WLSE)? the 4400 Wireless Lan Controller UI?

In any case, you can change individually the ip addresses of the access points from the WLC GUI, the WCS but there is no easy way to change it as a bundle.

In WLC UI: go to Wireless -> Access Points -> All APs. Click on the AP in question and in IP Config, uncheck static IP.

WCS : Configure -> Access Point. Click on the AP and change the IP.

I dont see a way to change this in a template for all the APs simultaneously on the software.

I suggest is to use the CLI on the WLC with the command :

(Cisco Controller) >config ap static-IP disable .

You can list all your aps in a file and then paste the output on the CLI of the WLC :

config ap static-IP disable AP1


config ap static-IP disable AP2



Be aware that your APs will reboot after entering this command.

If you want to keep static-IP and move it, you can have the following command line script to paste in your WLC :

config ap static-IP enable ' '


This will also reboot the AP as there is an IP address change.

Regardless of the code of WLC, check the release notes for open defects :

4400 WLC :

2100 WLC :


I'm running version on my Wireles Lan Controller.

Two questions...

1) Do I need both a wireless lan manager and the wireless controller?

2) When I reset the APs, they do not connect to my Wireless Lan Controller. What kind of configuration needs to go into Wireless Lan Controller and if there is something wrong?

Hi Pedro,

The "lwapp" enable command is disabled if the AP is running on the LWAP image. In enable mode, check if you have two IOS in the AP: one for LWAP and the rcovery image ("RCV" in the filename). If there is, you can delete the LWAP image (delete /f /r flash:) and allow the AP to boot into the RCV image before trying the "lwapp" enable command.

What are your AP's models? Firmware 3.X will NOT support 1140 & 1250 APs.

Hope this helps.

NOTE: Not being picky, but do you have an idea why are you still using the 3.X firmware?

Hi Pedro,

Managing Controller Software and Configurations

Have a read of the link above. Take special attention to Table 8-1 Upgrade Path. Before you do any upgrade, I recommend the following:

1. I will not recommend any version for you to upgrade to. This is your choice.

2. When choosing the version of your choice, read the Release Notes.

3. I recommend that you upgrade the Bootstrap FIRST. Bootstrap has the suffix -ER in the filename and contains patches and fixes not associated to the firmware.

Hope this helps.
