546 DHCP and USB Auto-Configuration

If the *.setup file configuration line contains an IP address but no

configuration or image 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 be using the

same configuration file and/or image on the USB device. This method allows

different IP addresses to be assigned, but the same configuration file or image

is downloaded to multiple switches. Alternatively, the line may contain a

specific configuration or image file name, or both.

After the current switch has been configured and/or upgraded and the

completion message is displayed on the switch, the current line in the *.setup

text file will be marked as used. This allows using the *.setup file for

additional switches without manually changing the file. The USB device can

then be removed and inserted into the next switch to begin the process again.

Also, the switch MAC address of a switch that has been automatically

configured is added to the beginning of the line (if no MAC address was

specified in the file) for lines using the IP address lookup method so that the

MAC and IP address combinations are recorded within the *.setup file for

future use bindings.

At the start of the next USB auto download, if all lines in the *.setup file are

marked as already “in-use” or “invalid,” and there is no MAC address match

for a switch, the process will halt, and a message similar to the following is

displayed on the console:

<###> APR 22 08:32:43 Error: Auto Configuration has terminated

due to there being no more lines available for use within the

USB file “XXXXX.setup”.

Configuration File

The *.text configuration file identified in the *.setup file contains the

running-config to be loaded on to the switch. The configuration file may be

specified on a line in the .setup file to assign specific configuration to specific

switches, or, if it is desired to assign a single configuration to all switches, the

configuration file need not be specified in the .setup file as long as it is

present on the USB device. The configuration file specified in the *.setup file

should exist on the USB device. It must have a .text file name extension. No

other file name extension is allowed. For information about the format and

contents of the *.text file, see Editing and Downloading Configuration Files.
