Connectivity Guide

• In the ZTD provisioning script, enter the URL locations of an OS10 image, CLI batch le, and/or post-ZTD script. Enter at least one
URL, otherwise the ZTD fails and exits to CLI conguration mode.
ZTD guidelines
• You can store the ZTD provisioning script, OS10 image, CLI batch le, and post-ZTD script on the same server, including the DHCP
server.
• Write the ZTD provisioning script in bash.
• Write the post-ZTD script in bash or Python. Enter #!/bin/bash or #!/usr/bin/python as the rst line in the script. The default
python interpreter in OS10 is 2.7.
Use only common Linux commands, such as curl, and common Python language constructs. OS10 only provides a limited set of Linux
packages and Python libraries.
• ZTD is disabled by default on automatically provisioned switch fabrics, such as Isilon backend, PowerEdge MX, and VxRail.
Cancel ZTD in progress
To exit ZTD mode and manually congure a switch by entering CLI commands, stop the ZTD process by entering the ztd cancel
command. You can enter ztd cancel only when ZTD is in a waiting state; that is, before it receives an answer from the DHCP server.
Otherwise, the command returns an error message; for example:
OS10# ztd cancel
% Error: ZTD cancel failed. ZTD process already started and cannot be cancelled at this stage.
Disable ZTD
To disable ZTD, enter the reload command. The switch reboots in ZTD disabled mode.
Re-enable ZTD
To automatically upgrade OS10 and/or activate new conguration settings, re-enable ZTD by rebooting the switch. Enter the reload
ztd command. You are prompted to conrm the deletion of the startup conguration.
NOTE
: To upgrade OS10 without losing the startup conguration, back up the startup conguration before ZTD runs the
provisioning script. Then use the backup startup conguration to restore the previous system conguration.
OS10# reload ztd
This action will remove startup-config [confirm yes/no]:
