Files and Directories

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.

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 parame-
ters 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 user-configured 
information, such as IP address, gateway, and mask informa-
tion, will be lost. Therefore, it is recommended that you keep a 
backup copy of this file at all times.

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 

 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 recom-
mended that you keep a backup copy of this file at all times.
