Hi. I have been running two 2960X switches(ver- 15.0(2)EX4) in stack. I need to downrade image to 15.0(2)EX3 due to bug in current image.
I tried below image to download on flash1 & flash2 through "copy tftp flash1" command but it gave error of timed out.
Pls suggest me how could i downgrade image in this scenario.
current image : c2960x-universalk9-mz.150-2.EX4.bin
Downgrade image : c2960x-universalk9-mz.150-2.EX3.bin

No, this is not from Rommon mode.
maybe your switch does not come with USB than.
here is an output from a 3850 look at the line before last
test#copy ?
/erase Erase destination file system.
/error Allow to copy error file.
/noverify Don't verify image signature before reload.
/verify Verify image signature before reload.

In this case you have to use tftp
copy tftp flash1
copy tftp flash2

Hi.
Ok, so you don't have 15.0(2)EX3 on the flash. If you want to downgrade to 15.0(2)EX3 than you need to download it from Cisco.com first and than load it to the flash via tftp or USB.

Hi Reza,
I have downloaded image 15.0(2)EX3 from cisco site. But when i try to download it via tftp "copy tftp flash" it gave error of timed out.
pls tell me how could i download this image in flash on both stack switches.
10-31-2014 04:44 AM
Do you have physical access to the switches? if you do load the IOS into a flash drive and insert it into the USB slot on the switch and copy from USB to flash.

I do have physical access of switches but i dont know process of downloading image in switch via USB. Also should i need to insert USB on both switches
Is there any reason of tftp process not working.
10-31-2014 05:13 AM
If you have access to the devices there is no reason to use TFTP. USB is soooo much easier. All you have to do it download the image into the USB insert it into each switch and copy from usb to tftp

Hi Reza..
Which command do i need to execute to copy image from usb to flash.
Also since there is single management in stack, how could i copy it on both switches.
10-31-2014 06:34 AM
The command to copy from usb to flash should be something like this
copy usbflash0: flash:<ios name>
for switch-2 it should be usbflash1 and flash1
do a ? after copy it will show you all the options you have.

Hi Reza.. Would this above command run in rommon mode since i dont see this option now in switch now.
