5. If there is no boot system command the Cisco 12000 Series 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 system from onboard Flash memory and to ignore Break at the next reboot of the system Router conf term Enter configuration commands one per line End with CNTL Z Router config config register 0x2102 Router config boot system flash filename Crtl z Router The server creates a default boot filename as part of the automatic configuration process 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 processor type name GRP Table 11 lists the default boot filenames A boot system configuration command in the configuration file in NVRAM overrides the default filename created for booting over the network Note If a bootable Cisco IOS software image exists in a Flash memory card or Flash disk installed in PCMCIA slot 0 or slot 1 the configuration register setting is overridden and the bootable Cisco IOS software image will be booted instead of the default TFTP bootable Cisco IOS software image cisco2 GRP through ciscol17 GRP Table 11 Default Boot Filenames Action File Name Bit3 Bit2 Bit1 Bit 0 Bootstrap mode 0 0 0 0 Default software 0 0 0 1 cisco2
