1142N autonomous to lwapp conversion question...

G'day All,
I have a handful of 1142n APs to convert to lwapp mode. I am ok the upgrade process (i.e: tftp the rcv file to the AP, run the archive command, boot the AP with the rcv file, etc) but what I'm confused about is if the 1142s I have currently have 1140-k9w7-tar.124-25d.JA what is the corresponding rcv file version? From the CCO I can't see a 12.4.25 version in the lwapp ios files. I can see 12.4.21a-JX, 12.4.23c-JA5, 12.4.23c-JA2, 12.4.18a-JA1.
Also under the Latest Release is the 12.4.21a-JX rcv file, but it is labelled as a WIRELESS LAN LWAPP RECOVERY version which I am not sure I can use.
Any help is greatly appreciated.
JS

G'day There Scott.
I've done a couple of test runs of this and everything went pretty successfully. I wanted to ask, as once the AP was rebooted pointing to the new rcv file, it would connect to the WLC and download a lower version of software. I used
c1140-rcvk9w8-tar.152-2.JA.tar as you recommended, but once the AP connected to the WLC is reported something like it couldn't find the correct software version, so it downloaded and ran the folllowing version of software:
12.4(25e)JA$.
Did I miss a step with the use of the RCV file or is it just simply the fact that the WLC on has 12.4(25) version software so that is what the AP takes from the WLC?
Cheers,
JS

LWAPP Conversion of 1252 AP failing

Hello. I am having trouble performing a simple autonomous to lwapp conversion on a 1252 .11n AP. It is the LWAPP model number, but of course it shipped with Autonomous code on it. So I have to convert.
I have version 3.4 of upgrade tool. I create the flat file with the one AP in it and enter all the necessary information. I use the upgrade tool TFTP server and navigate/select the image file: exact file is -> "c1250-rcvk9w8-tar.124-10b.JA3.tar". When I select upgrade I get an error indicating the recovery image is not a valid one.
Does anyone know what I am missing here? Can someone outline the steps? This is my first conversion attempt as I have been running 1000 Series APs for the past 3 years.
Thanks
Chuck

Try this:
Autonomous to LWAPP (Shortcut)
Requirements:
â¢ Image file (The recovery file has the prefix ârcvâ in the image name, such as c1200-rcvk9w7-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.
Procedure
1. Copy the recovery file to the AP using the following command:
archive tar /x tftp:/// flash:
2. Let the AP boot on this image:
boot system flash://.bin
3. Reboot the AP.
OPTIONAL
â¢ DO NOT ALLOW THE AP TO JOIN THE WIRELESS LAN CONTROLLER.
â¢ IF POSSIBLE, type the following commands:
ï¾ clear lwapp private-config (This will bring the AP to factory default.);
ï¾ clear lwapp ap ip address
ï¾ clear lwapp ap hostname
ï¾ clear lwapp ap controller ip address
4. Let the AP connect to the Wireless LAN controller.
OPTIONAL
If an AP refuses to join the Wireless LAN Controller, type the following command from the AP:
lwapp ap controller ip address

Autonomous to LWAPP - Air1261 APs

Hi All,
I have just download the Auto-to-LWAPP upgrade tool and it is saying that it does not upgrade Air1261 from Auto-to-LWAPP, is it so? If yes, then what is the procedure to convert Air 1261 APs from Autonomous to LWAPP?
Also, when I start the upgrade tool, it says that a TFTP server is already running on the PC so it will start the application with "User external TFTP" option, however there is not TFTP running on my PC. Why this error is coming? Following is the snapshot of the error.
Looking for valuable response.
Regards,
Sohail

Take a look at these links as it will explain how to convert the AP's.

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
Erik

Hi 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
Chris

LWAPP Conversion Error

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,
Scott

I 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.

1142 autonomous to lwapp

hi folks:
Has anyone of you tried to convert autonomous to lwapp mode? I used upgrade tool v3.4 and it said 1140 is not supported. Or is there any other way to do the conversion? Thanks.
regards
Alex

Was it a LAP to begin with? If so, follow the "LWAPP revert to autonomous" steps using the recovery image as your file. Yes - I know you are going to LAP, not to autonomous. These steps worked great for me when going from autonomous back to LAP (without using the conversion tool):
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 Set the timeout value on the TFTP server to 30 seconds.
Step 4 On the PC where the TFTP server is located, perform these steps:
a. Disable any software firewall products, such as Windows firewall, ZoneAlarm firewall, McAffee firewall, or others.
b. Ensure all Windows files are visible. From Windows Explorer, click Tools > Folder Options > View; then uncheck the Hide extensions for known file types check box.
Step 5 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, c1240-k9w7-tar.default for a 1240 series access point, and c1250-k9w7-tar.default for a 1250 series access point.
Step 6 Connect the PC to the access point using a Category 5 (CAT5) Ethernet cable.
Step 7 Disconnect power from the access point.
Step 8 Press and hold MODE while you reconnect power to the access point.
Step 9 Hold the MODE button until the status LED turns red (approximately 20 to 30 seconds) and then release.
Step 10 Wait until the access point reboots, as indicated by all LEDs turning green followed by the Status LED blinking green.
Step 11 After the access point reboots, reconfigure it using the GUI or the CLI.

Upgrading 1252s from autonomous to LWAPP

I need to upgrade several 1252s from autonomous to LWAPP.
I have not been able to find the upgrade tool for 1250s or instructions for CLI upgrade.
I wil be using NCS to do final configuration once the APs come online.
Can someone assist?
Thanks,
Kristin

So long as you pull the rcv file for the AP you should be able ti use NCS to do the conversion.
Other than that a standard AP upgrade should work, with the rcv file as well.

UPGRADE 1103 to 1159 - PAYMENTS CONVERSION QUESTION!

Hello,
UPGRADE 1103 to 1159 - PAYMENTS CONVERSION QUESTION!
This is the scenario, we are planning to do. Currently we have 11.0.3 in one box. We are planning for re-implementation for 11.5.9 in the new box. So we
have to convert approx 14 months of open and closed data for the historic purposes. (Like PO's, Invoices, Payments and ledger data etc.)
Again, these conversions cannot be handled through the front end using some Data Loader kind of tool etc...
Data Loader tool, I used a lot for loading Flexfield Value Set Values, Category Codes etc...
But my question is converting these AP_PAYMENTS related data in the back end. (Like Check num, Payment Batch ID, Invoice Number, Invoice ID, Supplier Number,
Supplier ID, etc.) from old 11.0.3 box to new 11i box.
Since there was some confusion is going on with Payments related areas, because there was now API's etc... some of them are telling it is very difficult to migrate "AS IS" into 11i. I also heard that oracle won't support this.
Just want to clarify clearly on this issues.
Because we are moving from the small box of 11.0.3 into Big box for 11.5.9. So we don't want to loose all the histories for about 20 months. especially open
Closed / Open - Invoices, Payments, PO's, REQ's, Active Items which are in the Open Blanket PO's, Employees, etc...
Of all these everything sounds like doable because they do have API's etc... Of course, I belive there is no API for the Vendors only. We want to know is this true for the Payments also.
Any urgent clarifications is very much appreciated with clear explanation.
Thanks in advance
Mani Varadan

The payment conversion is little bit tricky in term on its understanding and functionality.
There are lot of dependices of payments conversion on the others objects like invoice.
You need to be very clear in requirements.
Here is the extracted documents for giving you clear understanding about payments.
Overview of Process
Prior to creating a payment batch, four setup are required.
A.Define a bank for bank branches with which you do business.
B.Define bank accounts.
C.Choose a predefined or custom payment format.
D.Finally, define payment documents for disbursements for each bank account.
To give an overview of the steps required to create payment batch payments:
1) Initiate the payment batch by entering the criteria for invoices you want to pay. The payment batch process selects invoices, and then builds the payments. It determines which invoices will be paid on each payment document, and lists this information for you on the Preliminary Payment Register.
2) Make any necessary modifications to your payment batch, such as selecting additional invoices, deselecting invoices, deselecting suppliers, etc. Once modifications are complete, the modify payment batch process automatically builds the payments if any invoices were added.
3) Format payments to produce an output file.
4) Print checks from the output file if you are not creating electronic payments or sending the output file to a third party for printing.
5) Confirm the payment batch by recording the document numbers associated with each payment. During this step, the invoice status is updated to Paid and a document number is associated with the invoice and invoice payment.
As conversion(from 11.0.3 to 11.5.9) is concern step 3,4 is excluded from the standard processes.
These are the tables involved during the payment conversion.
AP_SELECTED_INVOICES_ALL
AP_INV_SELECTION_CRITERIA_ALL
AP_INVOICES_ALL
AP_PAYMENT_SCHEDULES_ALL
These are background (concurrent) processes involved in batch process consists of the following
a. Autoselect
b. Build Payments
c. Preliminary Payment Register
d. Format
e. Confirm
f. Final Payment Register.
10.7:
If you are using the application in character mode, navigate to the Reset Payment Batch form. The navigation path is
\Navigate --> Controls --> Payment --> ResetPaymentBatch.
Select the payment batch name and the system displays the status of the batch. Your options for proceeding vary according to the batch status.
11.5.8/9
You can perform actions on your batch in Payment Batches form by clicking on the Actions button. The appropriate actions are highlighted depending on the status of the batch.
THIS SECTION TALK ABOUT THE DETAIL TECHNICAL OVERVIEW
Payment Conversion Technical Overview
For the conversion is concern we are following four-step process
I.Defined and prerequisite steps as discussed above
II.Selecting the Invoice
III.Building the Payment
IV.Confirm
THESE ARE THE PREREQUISITE SETUP
We are assuming the bank set is already done from 10.7 to 11i.Bank set up means bank account id, and its corresponding payment format.
For this purpose we are using mapping function for bank account id and on that basis we are getting corresponding checks stock id.This means defining a payment documents for disbursements
SELECT INVOICES
When a payment batch is started one row for each record is created in the
AP_INV_SELECTION_CRITERIA_ALL table.
This table stores the criteria that a payment batch uses to select invoices for payments. The module name for the Auto Select process is APXPBSEL. The Select Invoices, or AutoSelect, is the first step in the payment batch process.
When we run a concurrent program the AutoSelect process starts by loading records that meet the invoice selection criteria into the table AP_SELECTED_INVOICES_ALL from the tables AP_INVOICES_ALL and AP_PAYMENT_SCHEDULES_ALL.
The criteria that AutoSelect uses to determine which record to select from AP_INVOICES_ALL and AP_PAYMENT_SCHEDULES_ALL is stored in AP_INV_SELECTION_CRITERIA_ALL.
To be sure that no duplicate invoices get selected, invoices that are already selected in another payment batch are not selected. Invoice payments that have no remaining payment amounts are not selected either.
BUILD PAYMENTS
The module name for the Build Program is APXPBBLD. From the list created by AutoSelect, the Build program determines which invoices will be paid on each
Payment document, and lists this information on the Preliminary Payment Register if Selected. The Build program is spawned when AutoSelect has completed. When the Build Program starts, the application uses information from the table AP_SELECTED_INVOICES_ALL to create rows in the table AP_SELECTED_INVOICE_CHECKS_ALL.
In addition to creating rows in the AP_SELECTED_INVOICE_CHECKS_ALL, the build payments program also performs the following tasks:
Assigns document numbers for payments
Assigns Check Ids
Renumbers the remaining documents starting from the first_available_document
Updates the payment batch status to BUILT
Since we are doing conversion from 10.7 to 11i where all payments need to converted hence we are keeping payment batch status as FORMATTED
CONFIRM
This is the final step for the payment batch process, where we will pick a payment batch from front end, and then making confirm. The menu for this
AP Payable =>Payment Batches form =>by clicking on the Actions button
Internally the confirm program first updates the AP_SELECTED_INVOICE_CHECKS_ALL records,
then transfers those records to
AP_CHECKS_ALL.
In addition, the AP_SELECTED_INVOICES_ALL
records are transferred into the corresponding
AP_INVOICE_PAYMENTS_ALL,
AP_INVOICES_ALL and
AP_PAYMENT_SCHEDULES_ALL.
Table Involved in Payment Batch Process
These are the various table involved in the payment process of 10.7 and 11i.It is recommended that if corresponding earlier conversion is done then use the mapping function to get the new value.
oAP_SELECTED_INVOICES_ALL
oAP_INV_SELECTION_CRITERIA_ALL
oAP_INVOICES_ALL
oAP_PAYMENT_SCHEDULES_ALL
oAP_SELECTED_INVOICE_CHECKS_ALL
oAP_CHECKS_ALL
oAP_INVOICE_PAYMENTS_ALL
oAP_PAYMENT_SCHEDULES_ALL
oAP_INVOICES_ALL
oAP_BANK_ACCOUNTS_ALL `
Common Issue:
1.Determine the status of the Payment Batch?
A: Query up the Payment Batch in the Payment Batches Summary window to view the status. If you can not get into the application, you can select the status from SQL*Plus:
SELECT status FROM ap_inv_selection_criteria_all
WHERE checkrun_name = ?<payment batch name>?;
2. Dont change the last update date
We are doing the conversion for payments, hence we cant change he last_updated_date to sysdate as this will create a problem by concurrent program, in that case we need to populate the field for FUTURE_DATED_PAYMENT=N
3. dont populate the value for INVOICE_PAYMENT_TYPE
If there are some prepayments in the conversion process donor populate this field and pass NULL, otherwise this will create a duplicate invoice, which will cause a problem for concurrent batch for payment.
Hope now you will be very clear about the process.
let me me offline, if you need further.

Upgraded outdoor 1310G bridge from Autonomous to LWAPP

I recently got a pair of outdoor 1310G bridge radios to create a bridge. I upgraded one of the APs from Autonomous to LWAPP so that it could connect to our 4402 controller so that it could be monitored and controlled by it.
Everything looks like it upgraded fine with the upgrade tool never got any errors however the file: Config_18June2009_95613.csv that is suppose to have a hash key so that I can load that into the WCS or directly into the WLC is blank nothing is in that document. So at the moment the AP is not joining up with the WLC. Anybody have any advice?
Thanks,
Ryan

Hi Ryan,
You can run 'debug pm pki enable' when the AP is trying to join to find out the hash key.

AP1602I autonomous to lighweight conversion problem

Hi guys,
I'm doing migration from autonomous to LWAPP for some 1602i APs. I followed the usual procedure with the recovery image but after downloading and rebooting the AP keeps its ip/gw settings and is neither using the DHCP option 43 nor the DNS entry (it has no DNS settings), also tried with the erase of startup config after and before the download but the ip/gw is always there.
I was able to connect to the AP with the rcv image running with the default Cisco user, i set the controller IP both with :
capwap ap controller ip address ip_address
and :
capwap ap primary-base controller_name controller_ip_address
After that the AP joins the controller, downloads the software, reboots but never joins the controller again, it seems that it looses the controller setting and of course with static ip address and no dns settings it can't retrieve the controller IP.
Ios in autonomous mode was 15.2(2)JB2, WLC is 8.0.100.0
Any idea ?
Must the AP have a different software level for the rcv image to clean up the static ip ?
Or is there a way to save the controller IP when the ap reboots with the rcv image ?
Tomorrow I'm going to call the on site people to do the "factory default" procedure, I think it'll fix the problem but anyway I've other APs to migrate and an answer is appreciated.

Autonomous to LWAPP with Cisco Prime 2.2

Hello, I need to know if exist any procedure to convert Autonomous to LWAPP access point with Cisco Prime 2.2.

Here are the Steps Cristian.
To create an autonomous AP migration template, follow these steps:
Step 1 Choose Design > Configuration > Wireless Configuration > Autonomous AP Migration Templates .
Step 2 From the Select a command drop-down list, choose Add Template, then click Go . If you are updating an already existing template, click the applicable template in the Template Name column.
Step 3 Complete the required fields. For information about the field descriptions, see: http://www.cisco.com/c/en/us/td/docs/net_mgmt/prime/infrastructure/2-0/reference/guide/prime_infr_ref.html
Step 4 To view the migration analysis summary, choose Operate > Wireless > Migration Analysis .
Note: After an access point has been converted to lightweight, the previous status or configuration of the access point is not retained.
Hope this will resolve your issue ;)

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.

Converting back AP 2600 from Autonomous to LWAPP

Hello,
I have Cisco AP 2600, Previously i had converted it from LWAPP mode into Autonomous-Mode. But now I need to revert it back to LWAPP mode.
Can anyone send me the link on how to do it ?

HI Imran,
Yes you can convert it to lightweight. Just need the lightweight recovery image.
http://www.cisco.com/en/US/docs/wireless/access_point/conversion/lwapp/upgrade/guide/lwapnote.html
For the LWAP conversion, use the recovery image (example: c1140-rcvk9w8-tar.124-25d.JAL.tar). after thatuse the command on the autonomous AP priviledge mode.
AP#archive download-sw /force-reload /overwrite tftp://10.10.10.1/c1140-rcvk9w8-tar.124-25d.JA.tar

Autonomous or LWAPP for fast roaming

We are looking to deploy wifi to support Tablet PCs. The software we are using is very sensitive to loosing its connection to the SQL database. I am worried particually about roaming. We need to use 802.1x for security and would like to use the MS IAS servier with EAP-TLS for authentication. We have 4 locations which should each be well covered by 3 base stations at each location. Medical providers need to be able to move around the office without losing connections. Time is more important than money. An hour of lost provider time (and when our app crashes it crashes hard) is worth avoiding with addition money. My questions are the following:
1. Do we need LWAPP or will autonomous with WLSE work for us? (Specifically for fast secure roaming, or quick handoff, or whatever it is we need)
2. Do we need to use EAP-FAST (and thus a Cisco AAA server) or will EAP-TLS with IAS be enough?
3. If we use LWAPP do we need WCS or will managing each 2000 series WLAN controller be enough?
4. Will all this work with my HP switches and Andtran routers?

1. Do we need LWAPP or will autonomous with WLSE work for us? (Specifically for fast secure roaming, or quick handoff, or whatever it is we need)
A: Go with LWAPP, more reliable, and easier to work with.
2. Do we need to use EAP-FAST (and thus a Cisco AAA server) or will EAP-TLS with IAS be enough?
A: I'd recommend, PEAP. More secure, and with everything Cisco, much easier to support, since TAC does not support the IAS server.
3. If we use LWAPP do we need WCS or will managing each 2000 series WLAN controller be enough?
A: If you are only contemplatign using 2006 at 4 locations, WCS wouldn't be a necessity. If you expand beyond that and decide to do something else, then yes WCS.
4. Will all this work with my HP switches and Andtran router?
A: It probably will, and it should, but for best results, going Cisco for the whole solution works the best.
Now, why go with 2006's? They are nice boxes, but you would need 4 of them. If you are static at 4 locatiosn with out need for growth, I'd go with a 4402-25. This is a single controller that can handle up to 25 AP's. With this, if you purchase the 1242 or the 1131, you can do HREAP, and keep all the subnets locally switched, that way if the WAN goes out, or the controller goes out, then the WiFi stays up for the local subnets. Naturally anything acrosss the WAN is not accessable.
That beign said, if you are backhauling everything to a central site anyway, might as well go with one 4402-25, single point of controll, instead of 4. And if you do need to add another site, then you still have 13 more AP's that can join instead of having to purchase another controller.
