WLAN controller redundancy
What is the method to provide redundancy to the WLAN controller
The unified access point allows a backup controller WLAN? In this case, the configuration of the two controllers is automatically synchronized?
The world of WLC is how an AP is covered in case of failure of a WLC. It is not without some "down time" in case of failure, but two controllers are active. You must keep in mind that the AP cannot be certified a WLC both so it of the best you can do when a WLC fails AP then must re - register with the backup, it is not a process completely seamless.
This has some really good info;

I bought a new controller (model 2500) Cisco wlan and a point of access from a provider certified Cisco. Can I register the controller on the
Site Web of Cisco to enable access download software associated with this controller? I want to download the latest version of the software "AIR-CTVM-K9-8-0-100-0.aes".
but I'm not allowed according to my profile.
So, how can I access the latest version of the software for my 2500 WLAN controller?
Can I register the controller on the Cisco website to enable access to download software related to this controller?
Yes and no.
The quick answer is no. your authorized reseller of Cisco should be able to "join" the serial number of your WLC in your Service Agreement and your Service agreement is attached to your CCO login.
If you go direct to Cisco, it will take time to get to the bottom of the details, you need to provide a lot of information so it's best to get your Cisco reseller to contact them.
We have awireless LAN Controller "Cisco 4402 with software version 188.8.131.52" we use the Access Point 'AIR-LAP1242AG-E' and his works fine, we bought the new APs with the model "AIR-LAP1142N-E-K9" but its not working with our controller and restart continuously. I connected the console and checked the logs from the console that is given below. Please let me know is this controller WLAN is compatible with the APs new or not, or do I need to upgrade the operating system of the LAN Controller and if I upgrade the operating system of the WLAN controller it will support the old APs or not.
Thank you in advance for your response and support.

Remember messages useful rate. Thank you.
Just need to activate authentication RADIUS and accounting on Cisco 4402 WLAN controller, so this controller WLAN what admins can be authenticated through a RADIUS server.
I want to assure you that I could connect via the console or the local user account, if the RADIUS auth/acct on WLAN controller does not work for some reason any. I don't want me locked out if RADIUS auth/acct does not work.
I have set up RDIUS for switches cisco 3750 and works very well.
any suggestions please.
Thank you very much.
You must set the order

I recently bought a 2112 a Wlan controller a number of LAP1042n Ap of the AP will not join the command and the message I get in the console of the AP, it is that the AIR-WLC2100-K9-6-0-199-4.aes firmware does not support this model? Can someone please verify that this is the case?
Firmware AIR-WLC2100-K9-7-0-98-0.aes to overcome this problem?
Thanks in advance
Yes, 7.0 doesn't suppoert he...
CHECK THE RELEASE NOTES for more details...
I'm a novice guy with computers.
Well, I re-formated my laptop and re-installed all the drivers, but my wirless lan controller does not seem to be in my device manager.
I was just wondering, if the driver needed to be installed in a certain order. I also had my add on the Vodaphone mobile card plugged into slot on the side that would make a difference?
in any well any help would be great
As far as I know that the WLan card was optional on this unit. In this case, if you bought the device with wireless network card that WLAN should appears in Device Manager. But if you bought the laptop without the WLan card you won't find it in Device Manager.
PS: The recovery CD already includes the WLan driver and you don't need to t in addition no driver to install.
I am designing a solution for a hotel WiFi facility. This is mainly to provide access to the visitors of the hotel.
I wonder bandwidth throughput on a per customer basis - which I know can be done on the controller.
I was also asked to verify if the use of data restrictions may be implemented by the customer.
For example, they want that the restriction of the use of 1 GB / 2 GB on their visitors, after which they are not able to access the network without additional authorization.
Is there a way to do this on a Cisco controller?
This doco is convenient for the speed limit:
In addition, Rasika explains very well vs TCP UDP in a blog:
Regarding limiting the total data of a user; I don't think it's possible with just a Cisco WLC. You would probably need some kind of third-party tool... I can't find much except this post earlier which is probably still very relevant:
I always thought that we need two WLAN controllers for reliable connectivity, just in case where a single controller down APs can reach the second controller (backup). one of the reference expertise Cisco, that no two controllers need after APs connect same controller down APs will continue to work. Can you someone confirm please?
My understanding if the controller of down and APs power recycling would be down. Any help would be appreciated.
I always thought we need two WLAN controllers for reliable connectivity just in case one controller goes down APs can join the second controller (backup).Fix.
one of Cisco expert mention that no need for two controllers after APs connect even controller go down APs will continue to work.IF the access points are in mode FlexConnect (and a local authentication server is present), it is possible, as long as the APs are NOT restarted.
We have set up a wifi zone based on a few 1131AG access points and a few Cisco 3750 integrated WLAN controllers. We are now trying to use web authentication for our comments area. No problem by defining a WLAN of COMMENTS and the associated VLAN. We have also managed to download a custom controller authentication web page.
However, when I try to display the custom page, both controllers of show me the internal default page (preview and during the phase of actual authentication).
Global web authentication settings are the following: Security--> Auth Web--> Web Login Page--> custom (downloaded).
On the controller software version is 188.8.131.52, and the page is an HTML page.
Reveal any help be appreciated.
What you need to do is set internally (by default) and hit apply, then play again to custom and click on apply. You can still see the defaul if you use the preview, but if you associate the SSID and open your web browser, you should get the webauth page. I hope this helps.
I formatted the laptop above using the hidden partition.
Since that the wireless network controller is not installed and I can not find the drivers for it.
Could someone help, please
Can you please post model mobile exact please?
Back to your problem: what did you do exactly? Have you installed original recovery image and try to reuse for laptop with factory settings?
Sorry for this question but I m confused a little. In General, after recovery image installation, all drivers must be installed correctly.
What is the status of your WIFI card in Device Manager?
I am eager to test a 1510 Aironet Wireless AP without running a wireless LAN controller, is it possible? I can't find any documentation to be able to do this.
Unfortunately, you need a wireless controller for the operation of the series of 1510.
The 1510 is a fist light access; in other words, there are firmware and options that only a controller can provide.
If you need a full air mesh AP, you can check in the 1520 series, which is available with a standalone IOS. If you just need a robust outdoor AP, the 1300 series is available as a standalone AP.
How can I disconnect client PC to help AP Wireless LAN controller 4402? Only, I can disconnect my APs but not the client of the AP.
Thanks in advance.
You're not the only one who is busy! :)
When you choose to "CONTAIN" an AP, client or something, it means that up to 4 of your KNEES, will adopt an approach of Robin and transmit a massive amount to authenticate the package for the poor bastard. Basically, he's got a back and the target will not be able to authenticate on your wireless network until you raise containment. So be sure you want to do this.
The main Web page, Ad - Hoc Snape. You can find the MAC address of your target customer wireless. Click on this. In a new page, you will find a number of drop-down menus. Choose "external", "malicious" and choose the number of APs, and then you choose contains.
\Hope this helps.
Suppose that the AP and controller communicate over a network of L3.
NAT can be done between the two?
For example, suppose that the AP is connected to a DSL router that is running NAT.
Yes, I worked on projects where we did a DRY VPN with NAT. As long as the AP is routable, it will call home.
I read in other threads that it is possible to use several Interfaces AP (disabled LAG) and have a port connected to a switch and the second trunk port connected to a second switch, with two switches in question connected with each other and running HSRP (our two 6500 hearts). My understanding on 5508 controller is very limited and I have just thrown into this, because it is a "high priority" project and is said today to sketch something for a meeting later, but if I connect it all together, it's then not create a loop? I guess my question is, is the data/network traffic through the 5508 in a trunk (port1) to another (port2) and I'll finish by fighting errors on my carrots, that data would be to pass a downlink of reference1 to port1 (for example), then again down port2 and on another soul?
I read through the version 6 of the document as we speak, but it is not particularly clear on the delivery of the goods.
Correct... you cannot divide ports if the WLC is configured for LAG. For your use, with 6 AP, then Yes, I don't see why using a port connected to different switches will cause performance problems. If it is a trial and you later decide that you will have 2 WLC, then connecto a swithc and develop WLC to the other switch and use LAG.
I want to upgrade my nc8430 (EM741AV) to the Standard WLAN n. is possible to do?
What card is accepted by my Board?
Thanks in advance,
Without hacking (modify) the BIOS (which I do not know how), you can install one of the adapters listed in the service manual for your laptop wireless.
There is no card n wireless supported for your model.
You must buy an external USB Wireless N adapter if you want faster connection speeds.
Installing an unsupported card will cause the laptop to put an end to started until the card is removed.
