Step 1 Use the appropriate commands to enter all the required variables and any optional variables described in preceding sections. Perform these steps in ROM monitor mode to download a file through TFTP. Whether or not the router performs a checksum test on the downloaded image: Length of time, in seconds, before the download process times out. Number of times the router attempts ARP and TFTP download. This is the default setting.Ģ-Detailed progress is displayed during the file download process for example: There are both required variables and optional variables.Ĭonfigures how the router displays file download progress.ġ-Exclamation points (!!!) are displayed to indicate file download progress. This section describes the system variables that can be set in ROM monitor mode and that are used during the TFTP download process.

Use the tftpdnld command only for disaster recovery, because it erases all existing data in flash memory before downloading a new software image to the router.
USE TERMINAL EMULATOR TO SPOOF MAC ADDRESS HOW TO
This section describes how to load a Cisco IOS software image from a remote TFTP server to the router flash memory. However, if the router is unable to boot Cisco IOS software, you can load new software while in ROM monitor mode. The standard way to load new software on your router is to use the copy tftp flash privileged EXEC command from the Cisco IOS software command-line interface (CLI). If you do not enter a filename, this command will boot this first image in flash memory. This feature is available if the ROM monitor version that is installed on your router is 12.3(8r)YI6 or later.įor more information about the ROM monitor boot commands, see the Cisco IOS Configuration Fundamentals and Network Management Guide.Īttempts to boot the image directly from the first partition of flash memory. After the IOS software boots up, all of the four Fast Ethernet LAN interfaces are enabled. Note In ROM monitor mode, only the Fast Ethernet LAN interface FE0 is enabled and is available for communication, while the other three Fast Ethernet LAN interfaces (FE1, FE2, and FE3) are disabled. The number in the prompt increments with each new line. See the boot command in the " Command Descriptions" section in this appendix.Īfter the router reboots, it is in ROM monitor mode. The router remains in ROM monitor and does not boot the Cisco IOS software.Īs long as the configuration value is 0x0, you must manually boot the operating system from the console. Reboots the router with the new configuration register value. Perform these steps to configure the router to boot up in ROM monitor mode the next time it is rebooted.

To use the ROM monitor, you must be using a terminal or PC that is connected to the router over the console port. This appendix contains the following sections: If there is no Cisco IOS software image loaded on the router, the ROM monitor runs the router.

You can use the ROM monitor to perform certain configuration tasks, such as recovering a lost password or downloading software over the console port. The firmware helps to initialize the processor hardware and boot the operating system software. The ROM monitor firmware runs when the router is powered up or reset.
