Catalyst 6500 Series Switch Command Reference—Release 8.4

Chapter 2 Catalyst 6500 Series Switch and ROM Monitor Commands
set boot config-register
The baud rate specified in the configuration register is used by the ROM monitor only and is different
from the baud rate specified by the set system baud command.
When you enable the ignore-config feature, the system software ignores the configuration. Enabling the
ignore-config parameter is the same as entering the clear config all command; that is, it clears the entire
configuration stored in NVRAM the next time the switch is restarted.
Examples This example shows how to specify booting from the ROM monitor:
Console> (enable) set boot config-register boot rommon
Configuration register is 0x100
ignore-config: disabled
console baud: 9600
boot: the ROM monitor
Console> (enable)
This example shows how to specify the default 16-bit configuration register value:
Console> (enable) set boot config-register 0x12f
Configuration register is 0x12f
break: disabled
ignore-config: disabled
console baud: 9600
boot: image specified by the boot system commands
Console> (enable)

Configuration register is 0x90f
ignore-config: disabled
console baud: 4800
