Boot and Image Files
Although the flash memory on OmniSwitch 6850 Series switches can contain many file types (e.g., log and snapshot files), there are four specific file types that provide key switch and network functions. These files include the boot.cfg file, boot.params file, boot.slot.cfg file, and image (.img) files.
boot.params File
The boot.params file provides IP address, gateway, and mask information for the switch. This information is required for Ethernet connections to the switch.
This file also contains default console port parameters (baud rate, etc.) and can be modified via the modify boot parameters CLI command.
In order 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 automatically gener- ated on the next system boot. However, all
boot.cfg File
The boot.cfg file stores your network configuration parame- ters. When you first boot the switch, no boot.cfg file is 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 22 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 /flash/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 recom- mended that you keep a backup copy of this file at all times.
