VIP Advocate.The flash memory of Cisco routers is usually internal or can be a removable flash card on higher end routers. However, it may happen that for various reasons the operating system image may not be available, maybe due to file corruption, flash memory corruption, accidental deletion, etc.

In this case the device does not have a valid image to load and therefore the router boots into ROM monitor mode rommon. This mode gives a reduced set of commands that essentially allow the administrator to manually run the boot sequence. The obvious prerequisite of this procedure is to have a valid IOS image, which is suitable for the device you want to put into operation, stored on a USB flash drive.

Once we have this resource, we must enter into ROM Monitor mode rommon. If the device did not have a valid IOS image in the internal flash memory, it will go directly in that mode. In this mode we can see the list of available commands using the question mark or help command:.

Note: The command is dir usbflashx: where x assumes a value of 0 or 1 depending on which USB port of the router you are using. Router format? Format operation may take a while.

You may need to tell the switch what file to retrieve from the usbflash0 device. Router dir? So if the router doesnt support usb I'll use the tftp route.

Nothing happens until you reload the router or you issue the command "copy start config" to reflect those configuration to the running-config file. You will copy cfg file in startup configuration on router.
