LWAPP Access Point IOS Upgrade?

Using a 4400 Wireless Controller and WCS how do you upgrade the LWAPP IOS on Access Points to the latest version or is this even necessary? My LWAPP access points are fully functional 1131's and converted 1230's, but I would like to know what the procedure to update ios's are when a new one comes out. Do these automatically install when you update the controller software or do I need to download new IOS periodically and copy it to the controller or WCS, etc? What do you think?

Hi Jim,
When a Lightweight AP is connected to the WLC it has the same Version as the WLC. For example if the WLC is running 4.0.155.1 the AP is running 4.0.155.1. If you upgrade the WLC to a new version the AP's are upgraded at the same time. There is no need to do anything with the AP's themselves.
Hope this helps!

LWAPP Access points flapping

Hi,
I have 1252 and 1260 LWAPP access points in 20 sites connected to a 5500 controller over WAN through flexconnect.
Last two weeks, i noticed that the access points associated to the primary controller keeps flapping.(ie) it stay in primary controller for a minute or two and then it goes off again and again. Moved the APs to the secondary controller. Again i see the same issue. Noticed that there is no issue with the bandwidth.
This issue happened so far in two sites. The issue happens with all the access points at both of these sites. Replaced the access points. Still no luck. So converted the APs to autonomous mode as a temporary fix. Please let me know the suggestions.
Thanks,
Abinaya

Hi Scott,
Thanks for your reply...me and abinaya with in same team
yes we have a huge gap between the AP up time and Joining time
Let me tel you in how we are connected...
We have 1000's of WAN link(MPLS) connected to Data Center.
In Data Center we have this WLC 5508
20 Locations are added to this WLC(Flex Connect), each location has 4-5 AP's
Points we observed.
When we change this AP's to Autonomus mode,its working fine. Even in autonomus mode AP has to reach DC for AAA
If the WAN link has some problem, it should effect other devices which connect to DC.
We replaced AP's...but no luck.
This happened with different locations,different controllers.
We found the below logs in all the AP's which met this problem.

LWAPP access points are unregistering from the controller

Our wireless controller network designed with one 4402 controller and 30 LWAPP 1000 series access points.
all lwapp access points are suddenly unregistering from the controller and registering with controller after few minutes. It was happen randomly 2 to 4 times in a day.
I am adding the attachment of log file please help me anyone know identified this problem.
Thanking you,

Hi,
What's the specific model of your 4402? How many access points do your controller support?
Can you also check if the uplink or distribution ports on your WLC goes up and down. Thanks.

Autonomous vs LWAPP access point

I am new to these 2 terms.
What's the main difference between autonomous and LWAPP access point?
Autonomous AP can work on it's own, while LWAPP need to be used with WNC?
If I need to deploy an wireless enironment, I should use LWAPP, right?

The main difference is autonomous do not require a controller to control the AP and it use WLSE for management software; the LWAPP require a WLC wireless controller to control all of the AP but provide ease of management for the communication / setting between APs, it use another management software call WCS.
If you will deploy many APs, LWAPP will be better for easier management. If only a few APs, autonomous is fine because do not require additional WLC.

How can I verify CAPWAP/LWAPP access point?

Hello,
I wonder how can I check / what command shoul I use on non-autonomous access points to see wether they are support capwap or they support lwapp??
Thank you folks..

Hello,
I think Leo means how to distinguish by autonomous and lightwieght. not between LWAPP and CAPWAP.
Autohomous APs have in their image nam: K9W7 while lightweight APs have K9W8. That is correct. But I think this is not the answer.
In order to distinguish if an AP uses LWAPP or CAPWAP you have first to know that:
- Some old APs support only LWAPP. They do not support CAPWAP (1010 and 1030 for example).
- CAPWAP started with WLC version 5.2. If you have 5.2 or later then your AP supports CAPWAP. (old APs metnioed above are not supported on 5.x. they are supported on up to 4.x).
- Some APs support CAPWAP only. They work onlyh on WLCs with version 5.2 and above that supports capwap. (1140 for example does not work with 4.x, 5.0 or 5.1). While some other APs may work with either lwapp or capwap (1240 works with lwapp if it joing WLC running 5.0 while it works with capwap if it joins WLC that runs 7.x).
Now, in order to know if your AP supports capwap or lwapp:
- You need to know if your AP has any limitation (if it is capwap only, lwapp only or can run on both).
- if your AP can run on both lwapp and capwap you can do follow the follownig steps:
* show version from the AP to know the IOS version running on it.
* Go to this link (wireless compatibility matrix): http://tiny.cc/k08thw
* in the page, look for your IOS versoin that you knew from show version command.
* find what is WLC version that your AP version corresponds to.
* If the corresponding WLC version is 5.2 or later then you are running CAPWAP. If your WLC runs 5.1 or earlier then you are running lwapp.

Switchport setup for lwapp access point running several ssid's

Hi all
when setting up an lwapp acces point, do I need to trunk all the vlans on the port to the ap? or do I only need to enable the management vlan to the acces point ? ie 1 vlan and normal access port ?
cheers
Carl

If its a LWAPP AP, then the switchport should be a ACCESS PORT.. this is just to get the IP address to the AP, then the AP wil try to join the WLC.. once the AP joins, the SSID and rest flow through the LWAPP tunnel..

LWAPP Access Points

Guys,
I have an issue in our Lightweight Access Points, we have 1242AG, the strange thing happen is, when I connect to the console to configure the access point, the text are garbled, I tried another access point but I got the same result, I used different hyperterminal application, change my console cable but still the same.
Anybody who can share the same experience what I have.
I check the Cisco Tac site maybe someone has already raise this issue but I did not find any.
Thank you.

I've had a lot of oddities with AP console connections as well (works fine on routers, switches, etc.) but not on AP's.
Using Putty - http://www.chiark.greenend.org.uk/~sgtatham/putty/
is your best bet if you aren't already using it.

LWAPP Access point wont advertise SSID's

I have a 4402 WLC and LWAPP AIR-LAP1131AG-E-K9 connected to it.
I have been wrestling with the config for sometime now.
I have a laptop right next to it that wont see the SSIDs I have configured being broadcast.
I have no idea why but I do have the following errors in the log.
Apr 17 11:37:59.091 sim.c:913 SIM-3-GW_MISMATCH: MAC address of the GW 00:0f:f7:32:c1:80 recieved in the JOIN Request differs from the cached MAC addr 00:00:0c:07:ac:64 of the Gw. Deleting the Gw IP 10.45.50.97 for the AP Mgr & sending ARP req. for resolv

I notice the first error related to the GW IP, but I am not sure where this is specified and why it is mismatched.
I also dont know what the second error means either about the wrong VLAN.
Please can anyone help!
Many thanks,
Neil

Ok I now understand why I am not seeing any SSID's
I am actually troubleshooting this remotely and have a laptop sat next to the AP. The laptop has a hard wired connection that when connected disables the Wireless adpater. Its a HP nc6400 laptop. I am not sure if it is a laptop setting or a GPO.
So the not seeing the SSID is fixed.
When I shutdown the switchport for the laptop. I did see the laptop pick up a DHCP address in the wireless scope I configured.
However this actually only worked once which was wierd.
I solved the gateway mismatch by actually putting the correct gateway address into ap-manager interface.
But I am still left with the message
Apr 17 11:37:49.080 spam_lrad.c:1107 LWAPP-3-DISC_INTF_ERR2: Ignoring discovery request received on a wrong VLAN (70) on interface (1) in L3 LWAPP mode
However this has been joined with another log entry;

The Mac address here is the Wireless Adapter of my test laptop.
The information of the WLC is

Possibly this is not what you are after but if you show me where to look that would be great.
It might be relevant but I have joined the AP to the switch with
switchport access vlan 70
switchport mode access
The config to the WLC is on a Gi port
switchport trunk encapsulation dot1q
switchport trunk allow vlan 2,11,70,80

I am wondering if I should have
switchport trunk native vlan 70 in here?

Wireless Access Points Specs.

Hello guys,
i need to ask about the different between SAP vs LAP vs CAP ( Wireless Access Points )
thanks in advanced
i hope that you help me out :)

Hope this helps:
SAP=Standalone (Autonomous AP)
LAP=LWAPP Access Point
CAP=Capwap Access Point
Q. What is CAPWAP?
A. In controller software release 5.2 or later, Cisco lightweight access points use the IETF standard Control and Provisioning of Wireless Access Points protocol (CAPWAP) in order to communicate between the controller and other lightweight access points on the network. Controller software releases prior to 5.2 use the Lightweight Access Point Protocol (LWAPP) for these communications.
CAPWAP, which is based on LWAPP, is a standard, interoperable protocol that enables a controller to manage a collection of wireless access points. CAPWAP is being implemented in controller software release 5.2 for these reasons:
To provide an upgrade path from Cisco products that use LWAPP to next-generation Cisco products that use CAPWAP
To manage RFID readers and similar devices
To enable controllers to interoperate with third-party access points in the future
LWAPP-enabled access points can discover and join a CAPWAP controller, and conversion to a CAPWAP controller is seamless. For example, the controller discovery process and the firmware downloading process when you use CAPWAP are the same as when you use LWAPP. The one exception is for Layer 2 deployments, which are not supported by CAPWAP.
You can deploy CAPWAP controllers and LWAPP controllers on the same network. The CAPWAP-enabled software allows access points to join either a controller that runs CAPWAP or LWAPP. The only exception is the Cisco Aironet 1140 Series Access Point, which supports only CAPWAP and therefore joins only controllers that run CAPWAP. For example, an 1130 series access point can join a controller that runs either CAPWAP or LWAPP whereas an 1140 series access point can join only a controller that runs CAPWAP.
For more information, refer to the Access Point Communication Protocols section of the configuration guide.

1130AG Access Point PoE Problem with Cat 3750G-24PS-E switch

I am having a problem on the PoE negotiation of Catalyst 3750G-24PS-E and 1130AG Access point. I used straight and cross cable for physical connection since by default the auto mdix per port of the switch is enabled/on. I used CLI, CNA and Web Device Manager on both devices to isolate and troubleshoot the problem but still the PoE negotiation on both devices won't work out. But when I used the access point into other switch (CE500 PoE Switch), the access point is working properly. Does anyone can help me to distinguish what the problem really is? The IOS Version of 3750G switch is 12.2(25) SEE2 and the 1130AG access point IOS Version is 12.3(8)JEA.

Hi Rob,
Thanks for your reply. Yes, I tried shut/no shut on the switchport many times. I saw that the switch grant power inline on the port but the port still can't/won't provide any power to boot up the access point.
Thanks,
Nelmar

IOS to LWAPP for 1130AG Access Points

We have initially installed IOS-based 1130 APs. If we would be upgrading it to LWAPP mode, could we pushed IOS-to-LWAPP upgrade thru the network? what procedures are required?

Hi Leopoldo,
This is possible and fully supported and can be done using the "LWAPP Upgrade Tool". Have a look at the following;
LWAPP Upgrade Tool Troubleshoot Tips
http://www.cisco.com/en/US/tech/tk722/tk809/technologies_tech_note09186a008072d9a1.shtml
Access points must run Cisco IOS Release 12.3(7)JA or later before you use the upgrade tool.
System Requirements
You can use the Autonomous to Lightweight Mode upgrade tool to install Cisco IOS Release 12.3(11)JX on these access points:
All 1100 series access points containing MP21G (802.11g) radios
***All 1130, 1230, and 1240 series access points
All modular 1200 series access points running Cisco IOS software and containing these supported radios:
802.11g: MP21G, MP31G
802.11a: AIR-RM21A-x-K9, AIR-RM22A-x-K9
All 1300 series access points in access point mode
http://www.cisco.com/en/US/docs/wireless/access_point/ios/release/notes/b311jx1.html
Cisco has released a free tool called the "Autonomous to Lightweight Mode Upgrade Tool" that allows selected Cisco Aironet autonomous access point models to be configured for lightweight mode operation.
The Autonomous to Lightweight Mode Upgrade Tool supports the following models:
Cisco Aironet 1240AG Series access points
Cisco Aironet 1230AG Series access points
Cisco Aironet 1200 Series access points that contain 802.11g (AIR-MP21G-x-K9) and/or second-generation 802.11a radios (AIR-RM21A-x-K9 or AIR-RM22A-x-K9)
Cisco Aironet 1130AG Series access points
**Cisco Aironet 1100 Series Access Points that contain 802.11g radios (AIR-AP1121G-x-K9)
Cisco Aironet 1300 Series Access Points/Bridges (AIR-BR1310G-x-K9 or AIR-BR1310G-x-K9-R). A Cisco Aironet 1300 Series operating in Lightweight Access Point Protocol (LWAPP) mode only operates as an access point. This series does not support LWAPP bridging mode.
The Autonomous to Lightweight Mode Upgrade Tool supports a process to migrate an autonomous access point from autonomous mode to lightweight mode. Unlike a VxWorks to Cisco IOS Software upgrade, this process is a Cisco IOS Software upgrade to the existing Cisco IOS Software image-not an operating system "swapout". In converted access points operating in lightweight mode, Cisco IOS Software continues to run on the access point, while LWAPP is used to communicate with a wireless LAN controller. Since LWAPP supports automatic access point configuration, there is no need to retain or convert the original autonomous Cisco IOS Software access point configuration.

Need some advice for AP IOS upgrade (Wireless Access Point 3702 Series) ?

Hi to all
I recently purchase a Wireless Access Point (AIRCAP 3702E-E) with 4 antenna, i will use this device like wifi hotspot in my home.
I would like to upgrade it but i see two kind of AP IOS :
Lightweight AP IOS Software
Autonomous AP IOS
What are the difference ?
In case of Lightweight AP IOS Software will be the one to choose, i have multiple IOS :
Wireless Lan, ap3g2-k9w8-tar.152-4.JB4.tar
Wireless Lan Recovery, ap3g2-rcvk9w8-tar.152-4.JB4.tar
Someone can tell me what is the difference between these two versions ?
Best Regards.
Elrick.

Hi Elrick,
Cisco AP AIRCAP3702E is Cisco enterprise unit. Cisco small business support WAP4410N, WAP121, WAP321, WAP551, and WAP561 AP. However I will answer your questions.
Lightweight AP ISO you can use it ONLY if you connect AP to wireless controller
Autonomous AP ISO for manage and modify AP by it self not required wireless controller.
Thanks,
Moh
