Boot and Image Files
Although the switch’s flash memory can contain many file
types (e.g., log and snapshot files), there are three specific file
types that provide key switch and network functions. These
files include the
boot.cfg file, the boot.params file, and image
( .img ) files.
boot.params File
The boot.params file provides IP address, gateway, and mask
information for the switch’s Ethernet Management Port
(EMP). This information is required for direct Ethernet
connections to the switch’s primary CMM.
This file also contains default console port parameters (baud
rate, etc.) and can be modified via the
modify boot parameters CLI command.
To be read by the switch, the boot.params file must be placed
in the /flash directory. If the file is deleted for any reason, a
new boot.params file will be generated automatically on the
next system boot. However, all user-configured information,
such as IP address, gateway, and mask information, will be
lost. Therefore, it is recommended that you keep a backup
copy of this file at all times.
boot.cfg File
The boot.cfg file stores your network configuration
parameters. When you first boot the switch, the boot.cfg file is
not present. This file is automatically generated when you first
issue a
write memory command to save your configuration
changes. The file is then automatically placed in the
/flash/working directory.
Important. Your switch must be running from the
/flash/working directory in order to save changes to the
boot.cfg file. Refer to “Working and Certified Directo-
ries” on page 31 for more information.
Once the configuration parameters stored in the boot.cfg file
are considered tested and reliable, the file can be copied to the
certified directory and become part of the “last known good”
software for the switch.
If all copies of this file are deleted and a system boot occurs,
your network configuration will be lost. Therefore, it is
recommended that you keep a backup copy of this file at all
times.
