3.
a. Viewing the configuration variables.
b. Setting the configuration variables:
Note When you're in the ROM monitor, any variable or parameter you set should be in
all uppercase, and any command that is typed should be in all lowercase. If you mistype
the case, the ROM monitor cannot process the command.
c. Saving the configuration variables:
rommon> command
The rommon command line interprets input a line at a time like the Cisco IOS
Software CLI.
You can enter a question mark (?) at the beginning of a rommon> prompt to get a
list of available commands for rommon.
The rommon interface keeps a history of the previous 16 commands a user
typed. To view the history, use the command history or the letter h to view the
list of commands in history. When the history is listed, users should see a numer-
ic value to the left of each command. The user can recall the commands by using
the repeat value or r value, where the value is the number to the left of the com-
mand shown during a history listing.
rommon> set
The ROM monitor loads the configuration variables for the switch before giving
the user access to the prompt. These variables include the location of the config-
uration file and the boot image that ROM monitor will look for. Use the com-
mand set with no options to view these variables.
rommon> PARAMETER=value
To set a configuration variable, use the parameter value exactly as it is shown in
the set command (these are case-sensitive) followed by a value. To nullify a con-
figuration variable, leave the value blank. For example, use the following com-
mand to clear the boot image that was specified for the switch:
rommon> BOOT=
rommon> sync
To save the configuration variables, use the command sync. This command saves
the new variables to NVRAM to be used the next time the switch is reset.
