Appendix C Using the ROM Monitor
Entering the ROM Monitor Mode
Using the upgrade rom-monitor Command
Use the upgrade rom-monitor command to upgrade the ROM monitor to a new version. Depending on
where the image is located, use the following commands to upgrade the ROM monitor:
•
upgrade rom-monitor file <URL>
•
upgrade rom-monitor preference <readonly | upgrade>
upgrade rom-monitors file <URL> command installs the new version of ROM monitor on the router
by taking the image from the location indicated in the URL. The image is in the form of “.srec’ file. It
will then reload the router.
Following is an example of the output when the upgrade version of ROM monitor is located at
tftp://223.255.254.254/ajayhn/c3745_RM2.srec:, and the system configuration has not been saved:
