LWAPP use as a L2
Hi,
I want to know whether we can use LWAPP as a layer 2 mode. If yes please provide the command and the method.
Stick to firmware 4.X and you can use the LWAP as L2.

Converting air-sap2602i-s-k9 from autonomous to LWAPP
Hi guys,
I need your expertise regarding how to convert from autonomous to LWAPP using AIR-SAP2602i-s-k9 with IOS version of ap3g2-k9w7-xx.152.-2.JA.
I'm following these commands but it is not available
debug capwap console cli or debug lwapp console cli
I cannot proceed to convert it Did I miss something or the 2600 series doesn't support LWAPP convertion ?
thank you
ErikHi Erik,
Those commands aren;t going to work, they're debug commands for a lightweight AP.
Here is the guide to upgrading:
http://www.cisco.com/en/US/docs/wireless/access_point/conversion/lwapp/upgrade/guide/lwapnote.html
It's pretty simple though, get the lightweight software follow the upgrade tool instructions to load new software.
Though, you have a newer AP so you'd be ok just to load the new software on, if it's only for a small amount this is fine.
Thanks

I am converting an 1131AG autonomous to LWAPP using the conversion tool v3.2. The conversion fails when checking input variables, specifically the text file containing the IP address, telnet username, telnet password, and enable password. I can't believe I'm doing something wrong, as I've read the doc on how to prepare this file and it's just a TXT file with comma separated values. As an example, I tried:
192.168.1.1,scott,password,password and saved it as "IP File.txt"
Can anyone tell me what is wrong with this information?
Regards,
ScottI meant telenet enabled.... Have you looed at the read me file:
List of Prerequisites before running Upgrade Tool 3.2
1) The Upgrade tool operates only on a PC with the Windows 2000/XP
work station operating system.
2) The Upgrade tool operates only with Cisco Aironet 1100, 1130, 1200,
1240, 1250, 1310(AP mode only) series access points and C3201 WMIC
running Cisco IOS Release 12.3(7)JA software or greater.
3) The person installing and running the Upgrade tool must be
logged in and must be the administrator of the PC.
4) If the Upgrade tool is used on WAN link then link speed should be greater
than or equal to 128 Kbps.
5) The Upgrade tool requires a valid IP file containing IP address,
Username, Password and enable Password separated by a comma, for
each access point to be upgraded.
Note: Have a check that no multiple entries for same AP are mentioned.
6) Presence of Fire-wall may result in download of image failure. So, have
a check of Fire-wall presence and its configuration.
7) All the access-points and Controller must have telnet service enabled.
8) Make a check whether the system time is configured properly.
Post a screen capture of the error if possible. -
Is there a way to configure an SNMP string on a lightweight access point (LWAPP)? WCS is running version 7.0.164.3. The 4402 controller is running version 7.0.98.0. The LWAPP is using image version 7.0.98.0. I can access the LWAPP using SSH and get to the enable prompt. Below are the commands I'm using.

If there is a way to add the SNMP community from the controller or WCS, please let me know.
Thanks,
TimHi,
ok.. Please correct me if my understanding are correct.. "You would like to poll LWAPP Via SNMP"?? is this right??
If So.
You cannot poll the APs directly, but will be able to get AP statistics by polling the WLC.
lemme know if this answered your question..

Trouble getting 1130AG LWAPP to Connect to Controller
I'm having trouble getting any of my 1130AG LWAPPs to connect to my WLC.
I have not configured my DHCP server to deliver option 43 or option 60.
However, I have manually configured the LWAPP using the CLI. I have assigned a static IP address, the default-gateway, gave it a hostname, and gave it the controller ip address.
When I issue the command:
show lwapp ip config
all of the information appears correctly.
However, the controller never registers the LWAPP.
This is a completely new setup, so there are no previous configs to contend with.
If I issue the command on the LWAPP:
debug lwapp client event
Two debug messages appear consistently every 3-5 seconds. They are:
*Mar 1 00:34:26.733: LWAPP_CLIENT_EVENT: spamResolveStaticGateway - gateway found
*Mar 1 00:34:36.733: LWAPP_CLIENT_EVENT: spamHandleDiscoveryTimer: Could not discover any MWAR
Any suggestions?
~ Vance R. GregoryYou have to put option 43 in hexadecimal no. below you will find an example of DHCP configurations on router that act as a DHCP for LWAPP in different network:
ip dhcp excluded-address 172.16.1.1 192.168.1.1
ip dhcp pool WAP_DHCP_SCOPE
network 192.168.1.0 255.255.255.0
option 43 hex f104c0a814f0
The hex string is assembled by concatenating the TLV values shown below:
Type + Length + Value
Type is always f1(hex). Length is the number of controller management IP addresses times 4 in hex. Value is the IP address of the controller listed sequentially in hex.
WLC IP is 192.168.20.240 f1+1*4+ac10.14f0 = f104c0a814f0
default-router 192.168.1.1 -
Hello all, I have a project ahead and I need to clarify some things before starting this project.
I will install a new WLC 5508 and I have 8 AIR-BR1310G-A-K9-R, so Im wondering if I can use them.
- Can this model be converted to LAP?, right now they are autonomous.
- I need to used them as AP not bridge and under the governance of a WLC. Could this be possible?
- The intention is to use them for outdoor operation. Should I use one or two outdoord antennas?.
- ANT-2506 could be a good choice?.
A lot of questions, I know, but please I need your support and expertise on this matter.
Thanks in advance!!To be able to use the AIR-BR1310G-A-K9-R you will need to convert them to LWAPP using the normal IOS upgrade procedure but instead of an IOS image use an LWAPP image.
Then once the unit is in LWAPP mode you can make it join the WLC with the different optiosn avilable and if you want to use them as a point to point link you need to use MESH setup.
Just in case here is the IOs upgrade procedure, remmber to use the correct image for your unit and that it is LWAPP.
RECOMMENDED UPGRADE TROUGH CLI:
The following are the proper steps to do an IOS upgrade in a CLI/Telnet
session (This is the recommended upgrade):
1st: Use a TFTP server in the computer that you are going to use for the
upgrades. If you don't have one, get the free TFTP server in the following
link:
http://tftpd32.jounin.net
Note: Make sure that the computer and the APs are in the same subnet. For
example and AP in default settings will have IP: 10.0.0.1, so you need to
have the computer as IP 10.0.0.2, subnet mask: 255.255.255.0.
2nd: Download the IOS image from the Cisco.com Web site.
Note: Do not "unzip" the image.
3rd: Open the TFTP server (make sure that the TAR file's name of the IOS
image is shown as in the web site, because sometimes it gets renamed to
"Download .tar" and if that happens you need to rename it). Browse the TAR
file and select it, then click ok.
4th: Telnet the unit, go to enable mode and enter the following command:
ap#archive download-sw /overwrite /force-reload tftp://IPAddress
of_the_tftp_server/name_of_the_IOS_image_you_downloaded
In this link, you must specify the extension, as an example:
ap#archive download-sw /overwrite /force-reload tftp://10.0.0.2/c1200-k9w7-tar.122-13.JA.tar
Note: The IOS image name is case sensitive, and it should be complete. -
H-REAP and Client Load-Balancing
I'm told by Cisco that H-REAP does not support client load-balancing.
We have a situation where we want to deploy LWAPPs using H-REAP into a conference room where training would take place.
Any suggestions on how to overcome the inevitable slowness these people are going to experience from being unevenly associated with the APs?
We can't re-write the application so we are looking for a wireless solution.
Anyone hear about how other organizations have dealt with this type of situation?
I'll be glad to supply more details if I am not being clear in my description of the problem.
Thanks in advance. All responses will be rated.
PaulThis is the functionality which is missing in H-REAP: Client and Network Load Balancing
"Radio Resource Management (RRM) load-balances new clients across grouped lightweight access points reporting to each controller. This function is particularly important when many clients converge in one spot (such as a conference room or auditorium) because RRM can automatically force some subscribers to associate with nearby access points, allowing higher throughput for all clients. The controller provides a centralized view of client loads on all access points. This information can be used to influence where new clients attach to the network or to direct existing clients to new access points to improve wireless LAN performance. The result is an even distribution of capacity across an entire wireless network.
Note: Client load balancing works only for a single controller. It is not operate in a multi-controller environment."
I suppose if we limit the number of users that can associate with a particular AP then we will achieve some client load-balancing. Though a hard limit on the number of end-users will also lead to situations where some end users will not be allowed any access. -
4404 WLC AP's will not connect
I have a network with 75 Ap's on it I am registering 65 of them on the WLC and the other ten I have 6 that when I search for them in the WCS I find them and they say that they are connected to the correct controller but the WLC doesnt show them connected then there are 4 that dont register at all I am using 2 ports on the WLC already what am I missing ?
Establish that the 'missing' APs actually work by unplugging a known-to-work AP and plugging the missing ones in. Check they power up, talk to WLC, etc...
If they register successfully, then it's likely a switchport config / cabling issue. If your failing APs are all in specifc areas / grouped together, it could also be worth considering other things like there being something wrong with a whole VLAN, Switch, etc..
If APs don't register, then could be a number of things;
1. AP is actually running IOS(!!)
2. AP has an SSC instead of a MIC, and the SSC Hash / AP MAC isn't installed on the WLC
3. AP has an inappropriate Static Config
4. Broken AP
Solutions
1 - Migrate from IOS to LWAPP using LWAPP Migration Utility
2 - Add the MAC & SSC Hash to each WLC in your mobility group
3 - Factory reset the AP to delete the static config
4 - RMA! -
1130 not connecting to controller after setting to HREAP
I had an 1130 AP connected to my 4402 controller running 4.2.207. I went to set the AP to HREAP and after I applied the HREAP setting, the AP rebooted and will no longer connect to the controller.
This is the error message I am getting on the controller.
WARNING: invalid slot ID (255) passed to REAP -Traceback=
0x4F026C 0x4F0394 0x498B24 0x491DC4 0x4AAF90 0x48DAC4 0x48E35C 0x197630o REAP -Traceback=
The AP part number is AIR-LAP1131AG-A-K9.
This AP was up and running with no problem until I tried to change it to HREAP.
Any suggestions on how I can recover this AP?
SethI had reloaded the AP last night using c1130-k9w7-tar.124-10b.JDA3.tar renamed to C1130-k9w7-tar.default. After the AP came up in Autonomous mode I then converted back to LWAPP using c1130-rcvk9w8-tar.124-21a.JA2.tar. Once the AP joined the controller and got the image it then rebooted and came up with the same error.
So after reading your response I deced to rename c1130-rcvk9w8-tar.124-21a.JA2.tar to c1130-k9w7-tar.default and let the AP load this image. After downloading the image the AP then joined the controller, got its image, then reloaded and succesfully joined.
Thank you for the help.

Unable to join AP to controller
Hi All,
I’m having a problem of joining new Aps( Ari-ap1242G-E-k9 ) to the following wireless LAN controller. WLC details as follows,
Model No - AIR-CT5508-K9
Software Version - 7.0.116.0
AP Model - ARI-AP1242G-E-K9
AP console logs attached in Error.jpg file
Thanks,
AsaI should have looked at your attachment first sorry about that. Speaking of upgrades, have you considered upgrading the 5508 IOS? 7.2.111.3 has been out since September and may have a fix for the error you are running into.
Also someone ran into the same issue here: https://supportforums.cisco.com/thread/335438
They fixed this by changing the country code of the AP to be the same as the WLC. 3 people confirmed this before I stopped reading this post.
You can see how to configure the country code for the LWAPP using CLI from this document, page 8-108:

WLC Guidelines L3 Transport Mode and functionality
Hi,
I'm implementing a LWAPP Solution and I would like to have some confirmation about LWAPP solution
If I understand right all the traffic from the WLAN client have to pass through the dynamic interface of the controller and there are no
opportunity to configure it in another way...
Best Practises suggest that LWAPP AP should be placed in a different VLAN (IP Subnet) from the LWAPP WLAN client and to use LWAPP L3 Transport Mode...
Which are the drawback if I put the LWAPP APs on the same VLAN(IP Subnet) as the LWAPP APs? If I implement the solution in this way I can still configure
LWAPP L3 transport Mode or it isn't working???
Thanks for sharing your opinionActually, Layer 2 LWAPP mode is considered depreciated by Cisco. Also, only 4400 controllers support Layer-2 LWAPP discovery. 2000 series WLCs doesn't.
The reason why Layer-3 LWAPP is preferable than Layer-2 LWAPP is "Layer-3 LWAPP discovery involves a series of steps in its algorithm and finds the candidate list of controller in different ways like DHCP option43, OTAP, DNA etc..,
Layer-2 LWAPP discovery just uses one method of controller discovery that is by using layer-2 broadcast in a LWAPP frame. Since, layer-3 lwapp uses a series of controller discovery methods, it is more secured and reliabel than layer-2 LWAPP mode. -
Problem to register upgraded AP 1242 to WLC 4402
Hi,
I am running a small Cisco WLAN with about 20 APs (all 1242) that are managed by two WLC 4402 (running v4.0.155.0).
WLCs are in Mobility group, serveral WLANs/VLANs are configured (including 802.1x, guest access with WebAuthentication etc.). All APs are configured for the same WLC as primary and the other as secondary. Everthing was working fine until I tried to upgrade another AP from IOS to LWAPP using the Cisco Upgrade tool.
After the AP was flashed and rebooted it started to discover a WLC but fails. The console messages look like this:
*Mar 1 00:00:05.962: %CDP_PD-4-POWER_OK: Full power - AC_ADAPTOR inline power source
*Mar 1 00:00:06.952: %LINK-3-UPDOWN: Interface FastEthernet0, changed state to up

*Mar 1 00:00:54.397: LWAPP_CLIENT_ERROR_DEBUG: No more AP manager IP addresses remain.
*Mar 1 00:00:54.397: %SYS-5-RELOAD: Reload requested by LWAPP CLIENT. Reload Reason: DID NOT GET JOIN RESPONSE.
*Mar 1 00:00:54.398: %LWAPP-5-CHANGED: LWAPP changed state to DOWN
The switchport of the AP is configured for the same VLAN as the management and ap-management interface of the controller (not native VLAN), the primary controller is set to master controller mode and I see no other error messages (e. g. on the WLC).
Does anyone know how to fix this problem?

What ports do LWAPP AP's use to talk to the controllers.
Upon boot what ports and protocols are used for the
LWAPP AP to find the Controller.
What we are trying to do is, If we have an AP on a
vendor site in which we have a Site to Site VPN connection.
Can we get the AP connected and have a device on the vendors site connect to our network?
Thanks for the Help.
PeteIf you are running version 5.1 or earlier the packets are encapsulated in LWAPP so the ports are UDP 12222 or 12223.
If you are running version 5.2 or later the protocol changed to CAPWAP which uses UDP ports. 5246 and 5247.
For mobility the controllers use UDP 16666 to talk to eachother and IP Protocol 97 to tunnel the client's traffic if tunneling is needed. -
Want to use LWAPP Bridge on mobile cart in our wireless deployment.
Want to use LWAPP Bridge on mobile cart in our wireless deployment.
Question.
I have several mobile carts that use an automous AP in bridge mode to connect to our wireless network. The cart machine connects to the ethernet port in the AP. We use this for ultrasound carts, moble video units, cardio-echogram machines. I need the same functionality, but I want to have the AP(s) be LWAPP for better managability and troubleshooting capabilities. I plan to put them in their own AP group.
How can I do this? Thank you in advance.No, but there is for the 1262 and 1142 which won't be discontinued for awhile yet probably. Most newer items are starting to have wireless cards installed in them thus removing the need for bridges, this is a trend that we will probably see more of going forward.
