Appendix B ROM Monitor

 

Console Download

 

 

 

 

Argument

Description

 

 

 

 

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.

 

 

 

 

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.
