How to upgrade Cisco IOS-Image over USBflash with a TAR-File.

Download the TAR-File from the Cisco Software Download Portal ( and copy the new IOS-Image in the USB Flash Drive.  The TAR File contains the .bin IOS Image and an additional set of html & other files. In our case we took the IOS-Version as a TAR-File because the Client needs the Web-Management via web browser.

1. Copy the new IOS-Image from usbdrive in to the flash memory

Switch#archive tar /xtract usbflash0:/c2960s-universalk9-tar.150-2.SE6.tar flash:

2. Now its start extracting the TAR-file into the Switch flash memory

2. Check if everything is copied into Flash Memory. Erase the old IOS and the vlan.dat if its present from the Switch flash memory

Switch#delete /recursive /force flash:/c2960s-universalk9-mz.122-55.SE7
Switch#delete flash:/vlan.dat

Delete flash:/vlan.dat? [confirm]


3. Erase the running and startup config

Switch#write erase
Erasing the nvram filesystem will remove all configuration files! Continue? [confirm]
Erase o….
nvram: complete

4. Set the new default IOS to boot system

I know that boot system take the ios were are avaliable to boot the system.
but to be sure that the correct ios version is booting set this command.

Switch#show boot
BOOT path-list : flash:/c2960s-universalk9-mz.122-55.SE7/c2960s-universalk9-mz.122-55.SE7.bin

Switch(config)#boot system flash:/c2960s-universalk9-mz.150-2.SE6/c2960s-universalk9-mz.150-2.SE6.bin

5. Dobble Check

Switch#show boot:
BOOT path-list : flash:/c2960s-universalk9-mz.150-2.SE6/c2960s-universalk9-mz.150-2.SE6.bin

6. Put the new config and save

Building configuration…


Switch#copy running-config startup-config
Destination filename [startup-config]?
Building configuration…

7. Reboot Switch for finisch the IOS-Image installation

8. After reboot check if the new IOS-Image is installed.
