Verifying the Configuration Register Setting
Enter the show version EXEC command to verify the current configuration register setting. In
ROM-monitor mode, enter the o command to verify the value of the configuration register boot field.
To verify the configuration register setting, perform this task:
Command
Router# show version | include Configuration register
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 ROM-monitor mode
and waits for user-entered ROM monitor commands. The new setting instructs the switch to load a
system image from commands in the startup configuration file or from a default system image stored on
a network server.
Router1# show version | include Configuration register
Configuration register is 0x2102
