LWAPP and Autonomous

hello friends,
I need your help. We have a 4402-12AP and a 1121G outside the unified wireless network.
There are 2 vlans confgured on the WLC4402, 101 & 102. The ap-manager, management interface and AIR-1000-AP are on the vlan101. The port on the switch for the management interface is configured as a trunk with 101,102 allowed.
The 1121G is configured with those vlans with trunk configured on the switch too.
The problem is that when I associate to the 1121G i can't see the clients of the Unified WLAN.
Any help would be appreciated.
Thank you.

Hi,
I believe you need to examine the configuration of the switch port your LWAPP is connected to. Here is the documentation:
"While Cisco WLCs always connect to 802.1Q trunks, Cisco lightweight APs do not
understand VLAN tagging and so should be connected only to untagged, access ports on
the neighbor switch. This is fundamentally different from how autonomous APs connect
to switches, which must be connected to 802.1Q trunking ports."
Hope this helps. Please let us know if this answers your problem.
Best,
Paul

Roll-back LWAPP to Autonomous IOS and retain a configuration

I have a WLC-4404-100 with a mix of c1131 and c1232 access points associated. All my AP's are LWAPP (either ordered as LWAPP or converted from IOS to LWAPP), and I have just realised that I have more than 100 AP's to be rolled out. I know that an LWAPP AP can be converted back to Autonomous IOS, but cannot seem to find a definitive explanation about the configuration state of the AP after it has been converted back to Autonomous IOS.
I wish to convert some of my AP's which have already been setup to connect to my controller back to Autonomous IOS. My problem is that they are already rolled out and installed in ceiling spaces etc, and are not easy to physically get to and plug into the console. When I issue the 'config ap tftp-downgrade tftp-server-ip-address filename access-point-name' command on the controller CLI for an AP, when it boots up into autonomous IOS, what is the configuration state? Is it a blank "factory default" configuration, or does it retain a configuration based on how it was configured on the controller? Will I be able to remotely access the AP over the wire at all?
Thanks in advance.

Try the following steps:
LWAPP to Autonomous
Requirements:
â¢ Image file (such as c1200-k9w7-tar.122-15.JA.tar);
â¢ AP is connected to the Wireless LAN Controller; and
â¢ AP can ping the TFTP server where the image is located.
Procedures:
1. Find out what AP needs to be converted from LWAPP to Autonomous mode by entering the following command:
sh ap summary
2. Enter the following CLI command on the Wireless LAN Controller:
config ap tftp-downgrade
3. The AP will download the software and after a reboot, the AP will be on Autonomous mode.
Does this help?

Lwapp to autonomous

Hi all,
I'm having a problem converting lwapp ap1231 to autonoumous mode. I followed all the steps on cisco docs, and also checked on other similar posts here on this forum.
First, I tried the tftp server with ip 10.0.0.10 set and tried to upload the image file "c1200-k9w7-tar.default". I held the mode until status went red and released and watched if it received image file from the tftp server but everytime it booted off with lwapp file. It's as if it never talked to the server at all. I changed several tftp servers, different file name and nothing worked out well.
So I moved on with using the wlc. I connected ap back to wlan and did "config ap downgrade...." and I received this error message "*Nov 12 15:32:06.737: lwapp_image_proc: unable to open tar file". I tried several file names ".default", ".tar" and kept getting same error message.
Please help me with this problem. Could it be the setting on the tftp server, corrupted tar files? I'm all out of idea.
Thanks in advance.

'just did the lwapp to autonomous conversion today (first time) via tftp following the document and it worked well.
1. try to download a fresh copy of the image and rename it to the specified filename.
2. check the ram of the ap if it has enough space, if not delete some files.
3. you can delete the image and do it from "ap: " mode.
4. check out the 'Reloading the Image" section of the attached document.
good luck!

1250 LWAPP TO AUTONOMOUS

Hi,
I can't seem to find the image for upgrading a 1250 from LWAPP to Autonomous?
Also do I need the upgrade tool? If so where can I find it? (No Controller)
Please can someone point me in the right direction?
Many Thanks.

jcomment,
There is an IOS image for the 1250 series AP on cisco's site, you must have a CCO account to access this. If you have access to that goto www.cisco.com, click on support> Download Software> Wireless> Access Points> Cisco Aironet 1250 Series> Cisco Aironet 1250 Series Access Point
then select IOS Software and you should get a list of versions.
In terms of converting this the easiest way is to use the mode button and do a reset.
Step 1 set your computer to 10.0.0.100 255.255.255.0
Step 2 Place image file into a TFTP server folder on your PC.
Step 3 Rename the access point image file in the TFTP server folder to c1250-k9w7-tar.default.
Step 4 Using an ethernet cable connect your PC to the power injector/AP
Step 5 Disconnect power from the access point.
Step 6 Press and hold the MODE button while you reconnect power to the access point.
Step 7 Hold the MODE button until the Radio LED turns a red color (approximately 20 to 30 seconds), and release the MODE button.
Step 8 it will download the firmware image and decompress it.
Step 9 After the access point reboots, you must reconfigure the access point by using the Web interface, the Telnet interface, or Cisco IOS commands.
Hope this helps.... Please rate helpful posts.

LWAPP and routed network

Hi, I wish to connect LWAPP AP on a remote office. The controler will be reachable through on OSPF L3 network. Moreover, I wish to define my WLAN VLAN on the remote office so as the WLAN client have a remote IP and are switched by the remote switch.
AP--[L3 swith]--OSPF---[L3 backbone sw]--[LWAPP controller]
Is this architecture possible ??? (either with a 4400 controler or with a WiSM card on a 6500)
Thanks for your help?

If you have Gig between the AP and controller, then I'd classify that as LAN :) I would not worry about LWAPP traffic.
The only way I'd recommend H-REAP is if you have resources at the remote site that need to be accessed directly from the wireless clients. Let's say you have a Cisco Call manager GW at the remote site. It would be inefficient to encapsulate the voice traffic via LWAPP and send back to the controller in the data center, only for the controller to send the packets back to the Call Manager GW on the remote network. It all depends where your resources are located. If I needed to keep traffic local to the remote site, then I might think about a 2006 or a small 4402. Remember if the link goes down with H-REAP, then so does any dot.1x authentication. I believe only static WEP and WPA-PSK will survive when H-REAP is cut off from the controller.

Changing from LWAPP to autonomous

I have a 1130AG access point in LWAPP mode with no controller. How can change it to an autonomous mode if I dont have access to a wireless controller.

Yes. Follow the link below and use the guide "Using a TFTP Server to Return to a Previous Release"

Convert APs LWAPP to Autonomous without WLC

How can I convert an Access Point with lightweight version to autonomous without a Controller??
Regards,

Hi Juan Carlos,
No worries my friend, this should work :)
Here is a conversion method;
Reverting the Access Point Back to Autonomous Mode
http://www.cisco.com/en/US/products/hw/wireless/ps430/prod_technical_reference09186a00804fc3dc.html#wp161272
You can convert an access point from lightweight mode back to autonomous mode by loading a Cisco IOS Release that supports autonomous mode (Cisco IOS release 12.3(7)JA or earlier). If the access point is associated to a controller, you can use the controller to load the Cisco IOS release. If the access point is not associated to a controller, you can load the Cisco IOS release using TFTP.
Using a TFTP Server to Return to a Previous Release
Follow these steps to revert from LWAPP mode to autonomous mode by loading a Cisco IOS release using a TFTP server:
Step 1 The static IP address of the PC on which your TFTP server software runs should be between 10.0.0.2 and 10.0.0.30.
Step 2 Make sure that the PC contains the access point image file (such as c1200-k9w7-tar.122-15.JA.tar for a 1200 series access point) in the TFTP server folder and that the TFTP server is activated.
Step 3 Rename the access point image file in the TFTP server folder to c1200-k9w7-tar.default for a 1200 series access point, c1130-k9w7-tar.default for an 1130 series access point, and c1240-k9w7-tar.default for a 1240 series access point.
Step 4 Connect the PC to the access point using a Category 5 (CAT5) Ethernet cable.
Step 5 Disconnect power from the access point.
Step 6 Press and hold MODE while you reconnect power to the access point.
Step 7 Hold the MODE button until the status LED turns red (approximately 20 to 30 seconds) and then release.
Step 8 Wait until the access point reboots, as indicated by all LEDs turning green followed by the Status LED blinking green.
Step 9 After the access point reboots, reconfigure it using the GUI or the CLI.

LWAPP to Autonomous/IOS

I have a Aironet LAP-1232AG (AIR-LAP1232AG-A-K9) that I need to downgrade to an Autonomous AP. I can't find any documentation on how to do this. I have downloaded c1200-k9w7-tar.123-8.JA2.tar and set up a tftp server, but the LAP won't connect.
Any help would be GREATLY appreciated!

Hi Tom,
Here is the related info :)

Ora 02290 when using qms_transaction_mgt and autonomous transactions

Hi all,
I'm using the qms procedures:
qms_transaction_mgt for openeing and closing transactions.
Somewhere in my procedure when the transaction is opened i call another procedure which contains a autonomous transaction.
The next time qms_transaction_mgt.close_transaction is called i get an ORA-02290: check constraint (HST65.QMS_NEED_TO_CLOSE_TRANSACTION) violated
When i debug the qms_transaction_mgt.close transaction the g_current_trans_id variable is empty, which indicates the transaction is allready closed.
When i remove the pragma autonomous_transaction statement and the commit statement from the procedure i call, the problem is resolved.
Version information:
Designer 9.0.2 with a with a Oracle 9i 9.2 database and Headstart 9i.
Does anybody know how i can resolve this or if this is a bug and how to fix it?
Thanks,
Yvon

Ian, Yvon,
It is unfortunately a know restriction that the CDM RuleFrame component of both Headstart for Designer 6i and Headstart for Designer 9i doesn't work in combination with autonomous transactions.
The reason is that the RuleFrame administration relies on information stored in 1. pl/sql package variables and 2. database tables. Using autonomous transactions (that involve CDM RuleFramed DML) causes this information to dissynchronize.
A year ago I investigated the possibilities to make autonomous transactions possible with RuleFrame but unfortunately this is fundamental problem: RuleFrame wants to combine multiple DML-actions into one logical transaction (gards this with the "need_to_close_transaction" constraint), while autonomous transactions intend to to the opposite: commit a part of a transaction while the rest of the transaction still is posted/not committed.
There is one exception: if you call an atonomous procedure that does DML on a non-ruleframe-enabled table (no TAPI triggers that intend to open/close the transaction, no CAPI etc), everything functions.
Problem explanation:
====================
1. Outer transaction is opened (by front end or TAPI triggers of first DML)
2. DML takes place
3. Autonomous transaction-procedure is called
4. Auto-transaction again tries (and succeeds!) to open the transaction, it doesn't see that the transaction is opened (db table qms_transactions is empty for the autonomous transaction on query)
5. DML within auto-transaction is posted
6. Auto-transaction closes transaction
7. Auto-transaction is committed
8. Outer transaction thinks the transaction is already closed, because the auto-transaction cleaned out the package variables when it closed the transaction.
9. Commit of the outer transaction fails as the deferred check constraint need_to_close_transaction avoids this to happen (rollback takes place because of this violation).
Hope this helps

Hi Andrew,
LAP always download the image run on a WLC (in this case 3850). So no point upgrade LAP independantly as it will always sync with image run on the controller it joins.
In this case you can upgrade 3850 to 3.3.2 (which is the latest image as of today) if you are not already running that code

WLC 5508 and Autonomous AP 1240 upgrade to Lightweight

Hi All,
very simple question, for who knows it... :-)
Does an autonomous Cisco AP 1240G/AG series upgraded to Lightweight register/associate to a WLC 5508 ??
I found some documention, it seems not:
These Cisco wireless LAN controllers support autonomous access points upgraded to lightweight mode:
• 2000 series controllers
• 4400 series controllers
• Cisco Wireless Services Modules (WiSMs) for Cisco Catalyst 6500 Series Switches
• Controller Network Modules within the Cisco 28/37/38xx Series Integrated Services Routers
• Catalyst 3750G Integrated Wireless LAN Controller Switches
The 5500 is not in the list...
However based in some posts and other webpages, it looks that the 1240 converted to LAP can join a 5508...
Somebody can help please??
MANY THANKS!!!
Alex Bertrán

Yes, it can. Always check release notes for controller code, it lists supported access points:

I am trying to implement Workflow to execute PL/SQL procedures that are currently executed manually on my project. Most of the procedures issue commits or rollbacks and per Oracle support I needed to use PRAGMA AUTONOMOUS_TRANSACTION in the Workflow "wrapper" procedures to prevent errors with workflow. This has been successful with the vast majority of our procedures, however, in at least one case, a procedure that we execute (inserting millions of rows, Gbs of data) never finishes.
At first I thought that workflow might be the problem, but I have tested the procedure outside of Workflow in SQLPLus with the PRAGMA declared with the same result.
If I execute the procedure without the PRAGMA from SQL Plus without workflow it finishes in just under 4 hours (the expected time frame). Any ideas about what might be the cause of this strange behavior?
The problem seems to be caused by the PRAGMA which I need to implement Workflow. Any help would be much appreciated.

This sounds like a database issue rather than a workflow issue. If it does not work from PL/SQL outside of workflow, then I would suggest logging a TAR with Oracle Support. Sounds like you have narrowed it down to an autonomous transaction that runs for > 4hours.
You might want to include a simple reproducible test case as well in the TAR. In the mean time, you could try and break down the amount of work being done into a number of PL/SQL calls instead of one. For example 4 * 1hour PL/SQL calls instead of 1 that lasts 4 hours and doesnt work.

Problems converting 1242AP from LWAPP to Autonomous

I tried to downgrade a 1242 LAP to Autonomous through a WLC using cisco's brief instructions:
Step 1 Log into the CLI on the controller to which the access point is associated.
Step 2 Enter this command:
config ap tftp-downgrade tftp-server-ip-address filename access-point-name
Seems easy enough, i copied the IOS file (c1240-k9w7-tar.123-7.JA5.tar) to my TFTP root. Then i ran the command mentioned above from the CLI of the WLC. The WLC takes the command but nothing happens, if i hold down mode and reboot the AP it retains its previous settings? Any ideas?

In the end i ended up using the a version of the IOS that was one iteration older and it worked......bizzare

LWAPP and MSS (Maximum Segment size)

I fell in the problem described in http://www.cisco.com/en/US/partner/tech/tk827/tk369/technologies_tech_note09186a0080093f1f.shtml
A server sent a MTU greater than 1500 and the frame wasn't able to pass thru a GRE tunnel.
I am asking if the same problem could happen passing thru an LWAPP tunnel. And if the answer is yes, is it possible to bypass the problem coding the "TCP ADJST-MSS XXXX" on the WLC interface controller?

FYI - A documentation bug that may apply here:
CSCse34118 Bug Details
LAG documentation incomplete
The 4400 series Wireless LAN Controllers (including the 4402, the 4404, the controllers on the WiSM, and the embedded controller in the 3750G) are not able to reassemble packets from fragments that arrive on different ports.
Where we see this problem is when the LAG is connected to a channel group that uses a load balancing method that fails to ensure
that all fragments of a given IP datagram are transmitted on the same port. If an IP datagram's fragments arrive on different
ports, then that datagram will be discarded. As a result, an AP may be seen to be unable to join the controller - for example,
the controller may fail to process the incoming LWAPP JOIN request. Or, an AP may join, but some large data packets that are in transit to a wireless client may fail to be forwarded from the switch to the AP.
Given the following options (from Understanding EtherChannel Load Balancing and Redundancy on Catalyst Switches):
port-channel load-balance {src-mac | dst-mac | src-dst-mac | src-ip | dst-ip | src-dst-ip | src-port | dst-port | src-dst-port}
src-dst-ip is the load balancing method recommended for use with a WLC LAG, and is the default on the 6500.
The following methods are expected to work, but have not been extensively tested, and would not balance the traffic as well:
dst-mac | src-dst-mac | src-ip | dst-ip
src-port, dst-port and src-dst-port are known not to work with WLCs.
Workaround: if the switch cannot be configured to use a supported load balancing method, then either configure the WLC not to use LAG, or use LAG with a single member link.
