Want to change AIR-CAP2602I-E-K9 from lightweight to autonomous mode

[StT2020]

Hi, i want to change lightweight mode to autnomous mode on my AIR-CAP2602I-E-K9

Therefor I downloaded the software ap3g2-k9w7-tar.153-3.JF15 and rename it to ap3g2-k9w7-tar.default. The file starts with

I start TFTP Server and hold the button and after the info "button is pressed, wait for button to be released..." on serial monitor appears, I stop pressing the button but nothing happend, the download did not start.

I try the same with AIR-LAP1142N-E-K9 and it works in same setup succesfully. File c1140-k9w7-tar.default is also on the TFTP server. I use TFTP Server winagents an Windows 10 system.

It seems that there is another Basic boot loader software, but no unusual because of different devices. 

What went wrong by trying to program AIR-CAP2602I-E-K9? I programm fout LAP1142N without any problem, but with two CAP2602 devices it did not work.

I check Ethernet transfer protokoll with wireshark, by CAP1142N I see a request from 10.0.0.1, when i try it with CAP2602I the ethernet transfer is quiet.

If someone needs additional information dont hesitade to contact me. 

thx for your help

 - Follow this procedure (instead) :

You need to perform these steps:

• Restart the Access Point
• While it loads the image in flash, press Escape, you’ll enter ROMMON mode:

The system boot has been aborted. The following

commands will finish loading the operating system
software:

ether_init

tftp_init

boot

• Set the IP address for the gigabit 0 interface:

ap:set IP_ADDR 10.0.0.1   ( ->change to subnet address of tftp server subnet if needed)

ap: set netmask 255.255.255.0

• Initialize the tftp, ethernet and flash subsystems:

ap: tftp_init

tftp_init success: You can now use tftp file system!

ap: ether_init

Initializing ethernet port 0...

Ethernet speed is 100 Mb - FULL Duplex

ap: flash_init

Initializing Flash...

...The flash is already initialized.

• Load the image from TFTP and extract it to flash:

ap:tar -xtract tftp://10.0.0.100/ap3g2-k9w7-tar.152-2.JB.tarflash         (->change tftp server address & filename accordingly)

• After it’s done, set the correct bootimage:

ap: set BOOT flash://ap3g2-k9w7-mx.152-2.JB/ap3g2-k9w7-xx.152-2.JB

• Boot the system:

ap: boot

Hi, thx for your fast answer.

I try to use your steps but it doesnt work.

Here are the whole serial Monitor:

additional information: 

There is no change, if i hit or not hit the escape key during ramp up.

I didn t get the answer "tftp_init success: You can now use tftp file system!" and i think that is the reason why the CAP didnt download the software from tftp server. Timeout is set to 600 sec in tft server settings. 

Do you have any other helpful steps, that enclose the problem 

Thanks a lot

Stephan

              >....tftp://10.0.0.10/ap3g2-k9w7-tar.153-3.JF15.tar: connection timed out
  - Check the tftp server's logs (is there an incoming connection from the AP ?) ; make sure that the tftp server is reachable from the same subnet  that the AP is on. Try to ping it from the AP (e.g.) (?)

Hi, 

i check logs in TFTP Server and there is no incoming from CAP just as checking with wireshark Ethernet transfer protokoll, no request from 10.0.0.1 (different to AP LAP1142, i see an request and starting download transfer on same hardware setup)

I can ping tftp Server from other linux device in subnet, but i cannot ping 10.0.0.10 from ap because AP told me "unkown command" when typing ap: ping 10.0.0.10.

I cannot ping AP (10.0.0.1) from linux device

I test the same routine on another CAP2602I-E-K9 with same result. Dont get messagt that "tftp_init success: You can now use tftp file system!" and cannot download from tftp Server. (I think tftp Server is working on port TCP 69, because it works stable with LAP1142.

Any other ideas for testing enclose the error

[Rich R]

I tested with my 1602 AP which is the same generation and it works fine.

Check https://community.cisco.com/t5/wireless-mobility-knowledge-base/access-point-rommon-recovery-ap-prompt-recovery-example/ta-p/3119495 and make sure you haven't missed any steps.  Also make sure you get all the commands exactly right and don't miss any parameters - eg in your above example I don't see DEFAULT_ROUTER getting set and flash seems to be missing the colon (:)

Also if you still have the CAPWAP software on the AP then just let it boot up, login and do the TFTP from IOS using the "archive download-sw" command which will extract the files and set the boot variable for you.  Just check that it's set correctly with "show boot" before you reload.

[StT2020]

Hi, 

it doesnt work. Same error 

DPAA Set for Independent Mode
DPAA_INIT = 0x0
tftp://10.0.0.10/ap3g2-k9w7-tar.153-3.JF15.tar: connection timed out
ap:

I think there is no capwap software on the device, because it boots in the way like post 1 (by pressing the button) or like the way i discript in secound post (with and without pressing escape during boot up)

I dont use default router because device is only in ethernet subnet with tftp Server (winagent) and wildshark linux device. There is no other device or gateway in ethernet subnet. But is set DEFALUT_ROUTER to tftp Server adress.

I try it twice do be clear that i dont miss any step or charactor. And from your destription step 3 i dont see. it goes directly in ap: command line, and abort at step 7.

Al this dicription from Rich R and marce1000 worked on CAP1142 device, so steps and doing a correct, but didnt work on the two CAP2602I-E-K9 devices.

[Rich R]

If it can't boot then that suggests there is no software on flash or the software is corrupted.
You can check what's on flash with "dir flash:"

>But is set DEFAULT_ROUTER to tftp Server adress.
Yes that should be fine.

I'm at a loss to why it's not working.  It's a basic procedure which has worked this way on IOS APs for years and I've used it myself on many different AP models without issue.  Attach your complete console log, from power-on, so we can see every command you typed and every response you got just in case there is something mis-typed or something else relevant which we might notice.   Save to a text file (.txt) and attach the file rather than pasting long logs into your reply.

Make sure that tftp server on DHCP server Mode

this will solve the issue

thanks

[Alnaas]

make sure that the TFTP server on DHCP server

hopefully this will solve the issue

[marce1000]

            >...make sure that the TFTP server on DHCP server
           @Alnaas      - Correcting ; your reply is invalid 

[Alnaas]

I have the same problem and when i put the tftp app. on the dhcp mode it works for me

                   - That may work , but it is not a requirement.
