  • Transfer the file from the TFTP server to the flash memory of the switch. This can be done by issuing the copy command on the switch.

    • Router#copy tftp flash

  • Check if the file has been transferred successfully to the router by executing the commands given below:

    • Router#show flash:

    Directory of flash:/

  • Configure the switch to load the new IOS version. If we reboot the system now, the old IOS file will be loaded.

    • Router#reload

    Proceed with reload? [confirm]

  • Instruct the switch to load the new file. The easiest way to do it is by using the boot system command.

    • Router(config)#boot system c2960-lanbasek9-mz.150-2.SE4.bin

  • Save the configuration and reload the device. We can verify that the newer version of IOS is being used by issuing the show version command:

    • Router#show version
