Appendix B ROM Monitor
Console Download
Error Reporting
Because the ROM monitor console download uses the console to perform the data
transfer, error messages are displayed on the console only when the data transfer
is terminated.
If an error does occur during a data transfer, the transfer is terminated, and an
error message is displayed. If you have changed the baud rate from the default
rate, the error message is followed by a message telling you to restore the terminal
to the baud rate specified in the configuration register.
y Optional. Sets the router to perform the download
using ymodem protocol. Default is xmodem protocol.
The protocols differ as follows:
• The xmodem protocol supports a 128-block
transfer size, whereas the ymodem protocol
supports a 1024-block transfer size.
• The ymodem protocol uses 16-bit CRC error
checking to validate each packet. Depending on
the device that the software is being downloaded
from, this function might not be supported by the
xmodem protocol.
r Optional. Image is loaded into DRAM for execution.
Default is to load the image into Flash memory.
x Optional. Image is loaded into DRAM without being
executed.
destination_file_name The name of the system image file or the system
configuration file. In order for the router to recognize
it, the name of the configuration file must be
router_confg.
