Juniper Device Agent
This document describes how to manually install Juniper device agents.
Juniper ZTP
For an option that's simpler and easier to support at scale, see Apstra ZTP, which shows you how to automatically boot and install Apstra device agents and prerequisite switch configuration.
Disable ZTP
If you want to install agents manually because a previous attempt to install them
with Apstra ZTP failed, you must first delete the ZTP mode (since it remains active)
with the command delete chassis auto-image-upgrade.
If you're going to provision the Juniper switch without ZTP (ZTP Disabled), make sure
that the ZTP process is disabled before proceeding. After logging into the switch
for the first time and setting system root-authentication,
configure delete chassis auto-image-upgrade.

root>Appy Initial Juniper Junos Configuration
Before installing Apstra device system agents on Juniper Junos devices, apply the minimum configuration below to the devices.
system {
login {
user aosadmin {
uid 2000;
class super-user;
authentication {
encrypted-password "xxxxx";
}
}
}
services {
ssh;
netconf {
ssh;
}
}
management-instance;
}
interfaces {
em0 {
unit 0 {
family inet {
address <address>/<cidr>;
}
}
}
}
routing-instances {
mgmt_junos {
routing-options {
static {
route 0.0.0.0/0 next-hop <management-default-gateway>;
}
}
}
}Configure super-user User
For the device system agent to connect to the Juniper Junos device, you must
configure a local device user with class super-user.

system authentication-order [ password radius ]
Configure IP address and Management VRF
Device system agents use the Junos mgmt_junos management-instance
VRF and the management interface (such as em0).

Configure SSH and NETCONF
Device system agents require Junos SSH and NETCONF access to be configured under
system services.

root>Add Junos License Configuration
You can add license configuration before installing the system agent (to make it part of the pristine configuration), but the preferred method is to add license configuration with configlets.
