The Purpose of the Configuration Register
The Purpose of the Configuration Register
The configuration register can be used to change router behavior in several ways, such as:
how the router boots (into ROMmon, NetBoot)
options while booting (ignore configuration, disable boot messages)
console speed (baud rate for a terminal emulation session)
The configuration register can be set from configuration mode using the config-register command. From ROMmon, use the confreg command. Issue the show version command to view the current setting of the configuration register:
