Console Download
You can use console download, a ROM monitor function, to download either a software image or a
configuration file over the router console port. After download, the file is either saved to the mini-flash
memory module or to main memory for execution (image files only).
Use console download when you do not have access to a TFTP server.
Note If you want to download a software image or a configuration file to the router over the console port, you
must use the ROM monitor dnld command.
Note If you are using a PC to download a Cisco IOS image over the router console port at 115,200 bps, ensure
that the PC serial port is using a 16550
universal asynchronous transmitter/receiver (UART). If the PC
serial port is not using a 16550
UART, we recommend using a speed of 38,400 bps or less when
downloading a Cisco IOS image over the console port.
