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.
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:
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.
