Auto Image and Configuration Update

file. If no dellswitch.setup file is available, the switch checks for a file with a 

*.text configuration file and a *.stk image file. If multiple .text files exist, the 

switch uses the dellswitch.text file. If multiple *.stk files are present, the 

switch uses the image with the highest (most recent) version. Finally, if no 

*.setup, *.text, or *.stk files are found, the switch proceeds to the DHCP 

Auto Configuration process.

The *.setup file can include the following information:

• MAC address of the switch (optional)
• Configuration file name (optional)
• Image file name (optional)
• IP address (mandatory)

The MAC address should be on the same line as the configuration file and/or 

image file name to allow a specific switch (identified by its MAC address) to 

be associated with a specific config file or image. If an IP address also exists 

on the line, this indicates a previous binding and requires this IP address to be 

configured for the management IP address. 

If the switch MAC address is not found within the .setup text file, the first 

line that contains an IP address and no MAC address and is not marked in-use 

will be used by the switch to assign the management IP address/netmask. The 

IP address line should include the configuration filename and/or image 

filename for the switch. This method allows a group of IP addresses to be 

handed out without regard to the specific switch identified by the MAC 

address. A switch will mark a line as invalid if it is read and failed to properly 

parse if, for example, it contains an invalid configuration, a duplicate IP 

address or an image file name that is not available. Once a switch selects an IP 

address from the file, it adds its MAC address to the line, marks the line as in-

use, and updates the file on the USB device.
If the *.setup file contains IP addresses but no file names, the management IP 

address will be assigned, and then the feature will search the USB device for 

files with the .text and .stk extensions, which indicates that all switches will
