Problem uploading ios into 2960x switch using xmodem.

krishna murthy — Fri, 08 Mar 2019 13:59:16 GMT

I have my flash directory empty in my catalyst cisco 2960x series switch.There is no .bin file present there. I tried uploading the ios using Xmodem protocol but an interrupt saying "NOT ENOUGH SPACE" pops out and on console i get.."cannot handle>1 setup packet in DMA mode Xmodem:: I/O error. I have formatted the flash directory and there is enough space in it. Looking forward for a solution. Thanks in advance..:-)

Did you notice the 2960X has a USB port? Guess what that is for?

You can command the switch to boot the IOS from a USB thumb drive (as long as the USB thumb drive is supported). You can also copy (from ROMmon) the IOS from a USB thumb drive to the flash of the appliance.

I am facing the same problem.

This will depend entirely on the make and size of the USB thumb drive being used. Not all USB thumb drive (aka flash drive) is supported.

In ROMmon, force the switch to boot the IOS found in the USB thumb drive using the command "boot usbflash0:IOS_filename.bin".

Once the switch boots up correctly, use the "archive download-sw" command to unpack/extract the IOS file into the switch.

Don't waste precious time by copying the IOS from the USB thumb drive into the switch in ROMmon mode.

You are correct. This never worked. tried "boot usbflash0:IOS_filename.bin" got read/write errors.

Tried tera term/hyperterminal to upload the ios via xmodem too. I/O error every time.

Hi,

Format your USB with FAT16 and give it a try...

If you are using USB console port while using xmodem, don't do it. It will not transfer anything. Use RJ45 console port for transfer using xmodem.

It worked for me.

USB don't work in ROMMON mode. Use xmodem while connected through RJ45 console port.

Use xmodem while connected through RJ45 console port. NOT USB CONSOLE PORT.

It worked for me.

USB won't work in ROMMON mode.
