HELP !! IOS upgrade failed with Cisco Aironet 1100

vannaktok · ‎06-01-2004

Hi,

After trying to upgrade the IOS of my AP1100, and waiting a long time (132 minutes instead of 5 to 15 min)... The loading of the IOS never stopped...

So I unplugged my AP and now I can't connect to it anymore. Even after trying to go to the default setting (press mode button while powering up the AP), I can't ping the AP.

Thanks for your help.

Here is alink that should get you up and running. Click on the Process Failure and work your way down to Recovering from a Failure.

Hi,

You can recover an AP1120 by using the mode button reset with image reload steps.

Using the MODE button

http://www.cisco.com/en/US/products/hw/wireless/ps4570/products_configuration_guide_chapter09186a0080184ad5.html#1040300

Using the MODE button

You can use the MODE button on the access point to reload the access point image file from an active Trivial File Transfer Protocol (TFTP) server on your network or on a PC connected to the access point Ethernet port.

--------------------------------------------------------------------------------

Note If your access point experiences a firmware failure or a corrupt firmware image, indicated by three red LED indicators, you must reload the image from a connected TFTP server.

--------------------------------------------------------------------------------

Note This process resets all configuration settings to factory defaults, including passwords, WEP keys, the access point IP address, and SSIDs.

--------------------------------------------------------------------------------

Follow the steps below to reload the access point image file:

--------------------------------------------------------------------------------

Step 1 The PC you intend to use must be configured with a static IP address in the range of 10.0.0.2 to 10.0.0.30.

Step 2 Place a copy of the access point image file (such as c1100-k9w7-tar.122-15.JA.tar for an 1100 series access point or c1200-k9w7-tar.122-15.JA.tar for a 1200 series access point) in the TFTP server folder on your PC. For additional information, refer to the "Obtaining the Access Point Image File" and "Obtaining TFTP Server Software" sections.

Step 3 Rename the access point image file in the TFTP server folder to c1100-k9w7-tar.default for an 1100 series access point or c1200-k9w7-tar.default for a 1200 series access point.

Step 4 Activate the TFTP server.

Step 5 Connect the PC to the access point using a Category 5 (CAT5) Ethernet cable.

Step 6 Disconnect power (the power jack for external power or the Ethernet cable for in-line power) from the access point.

Step 7 Press and hold the MODE button while you reconnect power to the access point.

Step 8 Hold the MODE button until the status LED turns red (approximately 20 to 30 seconds), and release the MODE button.

Step 9 Wait until the access point reboots as indicated by all LEDs turning green followed by the Status LED blinking green.

Step 10 After the access point reboots, you must reconfigure the access point by using the Web interface, the Telnet interface, or IOS commands.

We have been having a similar problen. The image is not corrupted--we don't have to use the mode button. If we repeatedly telnet to the wap and issue the upgrade commands, eventually, the wap upgrades.

(these are1100s, upgrade from (11) to (13) )

We use the Airwave Management Platform to do these upgrades, but packet captures for these, and for when we manually telnet to the wap and do the upgrade are the same.

I suspect that the entire image is being tftp'd to the wap because the number of UDP packets in a successful or unsuccessfull upgrade are about the same. But for some reason, the wap doesn't send the "extracting [image filename]" message back to the tftp server after the UDP frames cease. It just sits there and eventually closes the connection.

A successful upgrade takes about 15 minutes. A failure will take 45 minutes before contact is lost.

It's really irritating and unacceptible, but not fatal.

Hi Linda,

This is not an issue that I have seen from the field as far as TAC cases being generated as far as the command and subsequent upgrade not taking through the CLI.

The only real hot issues with upgrading on the Access Point is that sometimes you cannot use the browser due to memory requirements and with 12.2(15)JA you have to use CLI and a tftp server. Also if you are trying to upgrade through the browser you have to disable your popup blockers.

Just to verify the syntax of the command you should be using it is as follows?

AP# archive download-sw /force-reload /overwrite tftp://x.x.x.x/c1100-k9w7-tar.122-15.JA.tar

where x.x.x.x is the IP address of your tftp server and c1100-k9w7-tar.122-15.JA.tar is the name of your image.

Would be interested if you are do a "term mon" on your telnet server, does it appear to go through the IOS loading process before it disconnects?

Regards,

Charlie

Linda replies:

No, these are the commands I am using.

(This is what the Airwave management applications

uses too.) It is missing the force-reload switch

in the archive cmd.

delete /recursive /force flash:/update

archive download-sw /safe /overwrite tftp:///

copy running-config startup-config

reload

Linda replies:

I'm looking at the process with package capture, and I can see that it only does the IOS reload in a successful upgrade. These successes sometimes occur using the four cmds showns above. In the cases where it fails, it fails immediately after the stream of tftp udp frames end. From comparing the number of tftp frames in a successful upgrade to an unsuccessful upgrade, I think that the firmware is fully loaded at this point. It could be that the WAP is expecting an explicit reload command, and it doesn't get it. When I look at the frames of a successfull upgrade, however, it looks like the WAP does the reload spontaneously.

We have about 150 Cisco 1100s that we bought over the last year. Could there be slight differences between them and that is why it happens on some waps and not on others?

Hi,

I am also facing a problem regarding the firmware upgrade of cisco1100 AP.The firmware tar file gets downloaded to the access point but is not extracted.But the diffrence is i am trying to do it through SNMP.

The entries i set in the mib are

ciscoFlashCopyCommand.1:-->copyToFlashWithErase(2)

ciscoFlashCopyProtocol.1:-->tftp(1)

ciscoFlashCopyServerAddress.1:-->192.168.110.161

ciscoFlashCopySourceName.1:-->c1200-k9w7-tar.122-13.JA3.tar

ciscoFlashCopyDestinationName.1:-->

ciscoFlashCopyRemoteUserName.1:-->0

ciscoFlashCopyEntryStatus.1:-->createAndGo(4)

The tar file gets downloaded to the access point.But it is not decompressed and subsequent

reset results in the Access point not rebooting with the error "No IOS Image".

Can anyone help me out on this?

I never heard back from anyone on this thread after June either. Sounds like the same symptom via another route.
