When trying to convert AP1242 from Lightweight to Standalone, without a WLC, it results to a "Connection timeout". How should I interpret the output from the <debug ip packet 101> that I did on the 3750 switch, and where can I get the definitions of FORUS and MCI check?

Thanks in advance.

Using a TFTP Server to Return to a Previous Release

Thanks for the reply LEO. The provided link gives the same set of instructions as the one I posted under PROCEDURE FOLLOWED.

Anything else you migh think of? Might it be that setting the TFTP server on a switch won't do the trick?

Rasika Nayanajith · ‎06-25-2015

Did you setup switch itself as TFTP server ?

Use a PC as TFTP server & see, that should work, see below for more details

Manannalage,

Correct, the switch was set as TFTP server, by adding the following commands:

tftp-server flash:c1240-k9w7-tar.default
ip tftp source-interface vlan 10
ip defaut-gateway 10.0.0.1

I've done it with a PC in the past, but this time I only have a switch as an option; because my PC new AV/Firewall is blocking the TFTP traffic. It's just an hassle to get it unblocked from that 3rd party security team; which is why I wanted to use the switch instead.

%Error opening  (connection timed out)Loading "flash:/c1240-rcvk9w8-mx.124-25e.JAP1/c1240-rcvk9w8-mx.124-25e.JAP1"

This error message is telling me that the AP cannot "see" the IP address 10.0.0.1.

djeffdupre · ‎06-26-2015

Leo,

From my understanding the AP does connect to the TFTP server, based on the <debug ip packet 101> I pasted in the post, and the AP does see the server 10.0.0.5 and Image, based on the following output, just above "%Error opening....":

" image_recovery: Download default IOS tar image tftp://255.255.255.255/c1240-k9w7-tar.default "

The "%Error opening" looks more like the AP is having trouble extracting the Image, therefore causing a timeout after several attempts.

Leo Laohoo · ‎06-26-2015

connection timed out

I disagree. The error message "connection timed out" basically means the AP did not hear a response from the TFTP server.

Look at your TFTP server and see if there are any errors or messages coming from the AP?

What is the IP address of the TFTP server?

Is FW turned off on the TFTP server?

Problem found and resolved. Here is a recap of what i've done to successfully upgrade the AP:

A. I used cisco 3750 as TFTP server to get c1240-k9w7-tar.default image, but I kept getting:
%Error opening (connection timed out)Loading "flash:/c1240-rcvk9w8-mx.124-25e.JAP1/c1240-rcvk9w8-mx.124-25e.JAP1"...

B. I tried with ubuntu Xinetd tftp server, but I kept getting:
ERROR: Image is not a valid IOS image archive.Loading "flash:/c1240-rcvk9w8-mx.124-25e.JAP1/c1240-rcvk9w8-mx.124-25e.JAP1".

C. I did a search as to why the Image is being seen as not valid, and found the following:

Note: These are the causes of the error message:
-There is a problem with the TFTP server. Some TFTP servers might not support the transfer of big files. In order to resolve this, use a different TFTP server. You can use the TFTP server available at http://tftpd32.jounin.net/ leavingcisco.com for a WLC software upgrade.
-If you use the incorrect image for the upgrade, you have to use the original .tar file (downloaded from Cisco.com) for the upgrade and not the extracted .JA file.

Ref: http://www.cisco.com/c/en/us/support/docs/wireless/aironet-1200-series/43800-AP1200upgrade.html

D. I went on a windows desktop, and used Pumpkin tftp, and it worked like a charm.

Conclusion, despite having a connection properly set, the AP seems to be finicky about the tftp server being used. Pumpkin tftp is the way to go for me in the future.

thank you guys for assisting me with this issue.
