Level 1

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.

In this case you have to use tftp

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.

HTH

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.

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.

HTH

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.

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

HTH

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.

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.

HTH

 

 

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