Using USB Zero Touch Provisioning

To use USB Zero Touch Provisioning (ZTP):

Gather the files that you need from the source switch by using one of the following methods:
- Run clone.py, and then rename the file ztp.cln:
```
run script clone.py usb –o
```
- Use tar or WinZip to create a compressed file containing all of the files from the source switch, and then rename it ztp.lst.
- Create a plain text file with a list of all of the file names from the source switch, and then reanme it ztp.lst.
- Select .xos, .xmod, .cfg, .xsf, and .py files as needed, and then append "ztp" (not case sensitive) to the beginning of each file name.
Copy the necessary file(s) (dependant on which method you used) to the USB drive:
- clone.py.
- ztp.lst (compressed file).
- ztp.lst (plain text list), plus the files listed in ztp.lst.
- ExtremeXOS image, configuration, and script files, as needed.
Ensure that the receiving switch is unconfigured—either "just out-of-the-box" or run unconfigure switch {all | erase [all |nvram]}.
Insert the USB drive in the receiving switch.
Files found on the USB drive are processed in the following order:
- ztp.xos is installed to the inactive partition
- ztp.xmod is installed in the inactive parttion
- ztp.cfg is copied to primary.cfg
  Note
  When a configuration file is present, some processing is deferred until after reboot by using the ExtremeXOS autoexec.xsf capability. The deferred actions are:
  - Configuration files—autoexec.xsf issues a use configuration command, since ExtremeXOS does not recognize .cfg file unless the file is present at bootup.
  - Script files—Since script files are likely to modify the configuration, scripts are processed after implementing the configuration (.cfg) by autoexec.xsf.
  - Save—the last action of autoexec.xsf is to save.
  - Remove autoexec.xsf—autoexec.xsf file is automatically removed after it is processed for USB ZTP.
- ztp.xsf is run using the load script ztp.xsf command
- ztp.py is run using the run script ztp.py command

If the switch supports it, during the USB ZTP process the front panel LEDs display a flashing pattern instead of the usual link activity. If a stacking slot seven-segment display is available and the hardware supports it, the switch scrolls the letters "U S b". When USB ZTP finishes, the LEDs resume their normal behavior.
