Verifying the Configuration Register Setting

Enter the show version EXEC command to verify the current configuration register setting. In
ROMMON mode, enter the show version command to verify the configuration register setting.
To verify the configuration register setting for the switch, perform this task:
Command
Switch# show version
In this example, the show version command indicates that the current configuration register is set so that
the switch does not automatically load an operating system image. Instead, it enters ROMMON mode
and waits for you to enter ROM monitor commands.
