image found on the local flash, user has the option to either continue using the same image by
entering the command 'admin auto init stop" within a fixed amount of time as prompted on the
screen. If the user executes this command, then a BOF is created and saved on the local flash with
the image location pointing to the image on the flash. If the user does not execute this command,
then the system reboots again attempting to find an image through the auto-init process (that is,
sending out DHCP requests).
Configuration and Image Loading
The bootstrap image processes the initialization parameters from the BOF. The bootstrap image
attempts to locate the configuration file as configured in the BOF. Up to three locations can be
configured for the system to search for the configuration file. The locations can be local or remote.
The first location searched is the primary configuration location. If not found, the secondary
configuration location is searched, and lastly, the tertiary configuration location is searched. If the
configuration file is in a remote location, the bootstrap process saves it on the flash as cf1:/
default.cfg. Users must not delete this file or create a file with this name. The configuration file
includes chassis, MDA, and port configurations, as well as system, routing, and service
configurations. Like the configuration file, three locations can be configured for the system to
search for the files that contains the runtime image. The locations can be local or remote. The first
location searched is the primary image location. If not found, the secondary image location is
searched, and lastly, the tertiary image location is searched. Figure 5, Figure 6, Figure 7, Figure 8,
Figure , and Figure 10 describe the bootstrap process.
The following diagrams and paragraphs provide details of how the 7210 platform boot up on
power ON, how it obtains the Timos image file, the BOF file, the configuration file loads, the
image, and the configuration file to bring up the platform.
