Reference Information
If you set the boot field value to 0x2 through 0xF and there is a valid boot system command stored in the configuration file, then the router boots the system software as directed by that value. If there is no boot system command, the router forms a default boot filename for booting from a network server. (See Table 11 for the format of these default filenames.)
In the following example, the software configuration register is set to boot the router from onboard Flash memory and to ignore the Break function at the next reboot of the router:
Router# configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
Router(config)#
Router(config)# boot system flash [filename]
Router(config)# end
Router#
The server creates a default boot filename as part of the automatic configuration processes. To form the boot filename, the server starts with the name cisco and adds the octal equivalent of the boot field number, a hyphen, and the
Table 11 lists the default boot filenames or actions for the processor.
Note A boot system configuration command in the router configuration in NVRAM overrides the default netboot filename.
