Cisco Systems OL-11497-03 manual Boot slot # imagename command

Chapter 4 Troubleshooting the Installation

Performing Other Configuration Tasks

If you enter the boot command with arguments (that is, by instructing the system to boot from a specific source), you have these options:

–You can instruct the system to boot from a specific Flash SIMM image by entering the boot bootflash:filename command, or from a specific image stored on a PCMCIA Flash memory card by entering the

boot slot #: imagename command.

–You can instruct the system to boot from a network TFTP server either by sending broadcast TFTP requests by entering a boot filename command, or by sending a direct request to a specific network TFTP server by issuing a boot filename ip-addresscommand.

•When the boot field is set to 1, the system automatically boots using the first image found in the onboard Flash SIMM on the RP.

•When the boot field is set to a bit pattern other than 0 or 1, the router uses the software configuration register settings to compute the filename of a default system image stored on a network TFTP server. It then uses that system image to boot the router. But if the configuration file contains boot instructions, the system uses these instructions to boot the system, rather than using the filename it computed from the software configuration register settings.

To form this filename, the system starts with cisco and links the octal equivalent of the boot field value and the processor type in this format:

cisco<bootfieldvalue>-<processorname>

For example, the filename formation process would yield a range of filenames such as the following:

cisco2-grp

.

.

.

cisco17-grp

or

cisco2-prp

.

.

.

cisco17-prp

The system would use one of the filenames in this range to boot a default system image stored on a network TFTP server.
