546 DHCP and USB Auto-Configuration

What Is USB Auto Configuration?

The USB Auto Configuration feature can be used to configure or upgrade one

or more switches that have not been previously configured, such as when new

switches are deployed. Before deploying the switch, the following steps must

be performed:

Create a text file that contains IP addresses and netmasks (and optionally,

MAC addresses) and file names that are parsed and used to configure the

switch. The optional MAC address used to identify the switch is the MAC

address of the base MAC address of the switch, although the feature will

accept any of the switch MAC addresses (see "Switch MAC Addresses" on

page 181 for further information). The IP address and netmask are the

minimum required fields in the configuration file. Refer to the example

below for an explanation of the file format.

Copy the file onto a USB device, along with any desired switch firmware

and configuration files.

Insert the USB device into the front-panel USB port on the

switch.

When the Auto Configuration process starts and no saved startup-config file

is present on the switch, the feature automatically searches a plugged-in USB

device for information.

What Files Does USB Auto Configuration Use?

The USB Auto Configuration feature uses the following file types:

• *.setup file for initial switch configuration

• *.text file for configuration information

• *.stk file for software image installation

The Auto Configuration feature first searches the USB device for a file with a

*.setup extension. If only one .setup file is present, the switch uses the file.

When multiple *.setup files are present, the switch uses only the

dellswitch.setup 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

NOTE: Neither USB Configuration nor Auto Install is invoked if a saved startup

configuration file is on the switch.
