Cisco Aironet Access Points IOS Recovery
Cisco AP (1200 Serials and 1300 Serials) only can carry one IOS.
“boot system flash:/xxx.bin" does not work for AP. Command line take the statement,
but "sh run" does not show it. "sh boot" will reflect the IOS which is specified.
never use "copy tftp flash:" in Cisco AP. It does not work.
Cisco 1310G IOS Upgrade Procedure:
Following is the proper command that you should use for a regular IOS upgrade with a .tar file on these Aironet devices:
ap#archive download-sw /overwrite /force-reload tftp://IP Address of the PC/the name of the IOS image you downloaded, even with the .tar extension Note: The IOS image name of the .tar file is case sensitive, and it should be complete.
Recovery Steps:
Using the CLI
Follow the steps below to reload the wireless device image using the CLI. When the wireless device begins to boot, you interrupt the boot process and use boot loader commands to load an image from a TFTP server to replace the image in the wireless device.
Note:- your wireless device configuration is not changed when using the CLI to reload the image file.
Step 1 Open the CLI using a Telnet session or a connection to the wireless device console port.
Step 2 Reboot the wireless device by removing power and reapplying power.
Step 3 let the wireless device boot until it begins to inflate the image. When you see these lines on the CLI, press Esc:
Loading “flash:/c350-k9w7-mx.v122_13_ja.20031010/c350-k9w7-mx.v122_13_ja.20031010″ …########################################################################### ################################################################################ ################################################################################ ####################
Step 4 When the AP: command prompt appears, enter the set command to assign an IP address, subnet mask, and default gateway to the wireless device.
Note You must use upper-case characters when you enter the IP-ADDR, NETMASK, and DEFAULT_ROUTER options with the set command.
Your entries might look like this example:
ap: set IP_ADDR 192.168.133.160
ap: set NETMASK 255.255.255.0
ap: set DEFAULT_ROUTER 192.168.133.1
Step 5 Enter the tftp_init command to prepare the wireless device for TFTP.
ap: tftp_init
Step 6 Enter the tar command to load and inflate the new image from your TFTP server. The command must include this information:
•the -xtract option, which inflates the image when it is loaded
•the IP address of your TFTP server
•the directory on the TFTP server that contains the image
•the name of the image
•the destination for the image (the wireless device Flash)
Your entry might look like this example:
Step 7 When the display becomes full, the CLI pauses and displays <!–

Note Keep pressing spacebar to complete decompress the file. If you do not press the spacebar to continue, the process eventually times out and the wireless device stops inflating the image.
Step 8 Enter the set BOOT command to designate the new image as the image that the wireless device uses when it reboots. The wireless device creates a directory for the image that has the same name as the image, and you must include the directory in the command. Your entry might look like this example:
ap: set BOOT flash:/c350-k9w7-mx.122-13.JA1/c350-k9w7-mx.122-13.JA1
Step 9 Enter the set command to check your bootloader entries.
ap: set
BOOT=flash:/c350-k9w7-mx.122-13.JA1/c350-k9w7-mx.122-13.JA1
DEFAULT_ROUTER=192.168.133.1
IP_ADDR=192.168.133.160
NETMASK=255.255.255.0
Step 10 Enter the boot command to reboot the wireless device. When the wireless device reboots, it loads the new image.
ap: boot
