Boot Using ZTP
Zero Touch Provisioning (ZTP) is used to deploy minimal configurations on several chassis. ZTP is used to
boot, set up, and configure the system. Configurations such as configuring the management ethernet interface,
installing SMUs, applications, and optional packages can be automated using ZTP. ZTP does not execute if
a user name is already configured in the system.
ZTP auto provisioning involves:
•
Configuration:
Downloads and executes the configuration files. The first line of the file must contain
!! IOS XR
for ZTP to process the file as a configuration.
•
Script:
Downloads and executes the script files. These script files include a programmatic approach to
complete a task. For example, scripts created using IOS XR commands to perform patch upgrades. The
first line of the file must contain
#! /bin/bash
or
#! /bin/sh
for ZTP to process the file as a script.
The user can either use the ZTP bash script or the ZTP configuration file.
host n1k {
#hardware ethernet 00:a0:c9:00:00:00;
option dhcp-client-identifier "<chassis-serial-number>";
filename "http://<IP-address>/<folder>/ncs1k-ztp.script";
#filename "http://<IP-address>/<folder>/ncs1k-ztp.cfg";
}
The following is the sample content of the ZTP bash script.
#! /bin/bash
#
# NCS1K Demo Sample
# ZTP installation of config and day-0 SMU's
#
source ztp_helper
wget http://downloads.sourceforge.net/project/yourcode/application.tgz
#install the downloaded application.tgz
#Run XR CLI’s from the script
`xrcmd “show version”`
The following is the sample content of the ZTP configuration file. The user can automate all the configurations
such as configuring the management ethernet interface, slice provisioning, and so on.
