Console Download

You can use console download, which is 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.

Command Description

The following are the syntax and descriptions for the xmodem console download command:

xmodem [-cyrx] destination_file_name

c Optional. Performs the download using 16-bit cyclic redundancy check (CRC-16) error

checking to validate packets. Default is 8-bit CRC.

Note The IAD2435 IAD only supports c and y.

y Optional. Sets the router to perform the download using Ymodem protocol. The default

is Xmodem protocol. The protocols differ as follows:

• Xmodem supports a 128-block transfer size. Ymodem supports a 1024-block

transfer size.

• Ymodem uses CRC-16 error checking to validate each packet. Depending on the

device that the software is being downloaded from, this function might not be

supported by Xmodem.

Note The IAD2435 IAD only supports c and y.

r Optional. Image is loaded into DRAM for execution. The default is to load the image

into flash memory.
