2. The services gateway functions as a DHCP server and automatically assigns

an IP address to the management device. Ensure that the management

device acquires an IP address on the 192.168.1.0/24 network.

If an IP address is not assigned to the management device, manually

conﬁgure an IP address in the 192.168.1.0/24 network. Do not assign the

192.168.1.1 IP address to the management device, as this IP address is

assigned to the services gateway. By default, the DHCP server is enabled

on the fxp0 interface and L3 VLAN interface, irb.0 (interface ge-0/0/1 to

ge-0/0/14, which is conﬁgured with an IP address of 192.168.2.1/24).

Conﬁgure the Device Using ZTP with Juniper

Networks Network Service Controller

Zero Touch Provisioning (ZTP) enables you to complete the initial conﬁguration

of the SRX345 Services Gateway in your network automatically, with minimum

intervention.

Network Service Controller is a component of the Juniper Networks Contrail

Service Orchestration platform that simpliﬁes and automates the design and

implementation of custom network services that use an open framework.

How to Set Up Your SRX345 Services Gateway 5

For more information, refer to the Network Service Controller section

in the datasheet at http://www.juniper.net/assets/us/en/local/pdf/

datasheets/1000559-en.pdf.

To conﬁgure the device automatically using ZTP:

NOTE: To complete the ZTP process, ensure that the services gateway

is connected to the Internet.

1. Access the J-Web interface (https://192.168.1.1). The recommended browser

is Internet Explorer version 10 or 11, Mozilla Firefox version 40 (or later), or

Google Chrome 55 (or later).

2. If you already have the authentication code, enter the code in the webpage

displayed.

On successful authentication, the initial conﬁguration is applied and

committed on the services gateway. Optionally, the latest Junos OS image is

installed on the device before the initial conﬁguration is applied.

If you do not have the authentication code, you can use the J-Web setup

wizard to conﬁgure the services gateway. Click Skip to J-Web and follow the

procedure in the “Conﬁgure the Device Using J-Web” section.

How to Set Up Your SRX345 Services Gateway 8

Verify the Settings

Access http://www.juniper.net to ensure that you are connected to the Internet.

This connectivity ensures that you can pass trac through the services gateway.

If the page does not load, perform the following checks to see if you can identify

the problem:

•Verify your conﬁguration settings, and ensure that you have applied the

conﬁguration.

•Check if the ISP-supplied device connecting your SRX Series device to the

Internet is turned on and working properly. Try turning it o and on again.

After you complete these steps, the SRX Series device can pass trac from any

trust port to the untrust port.

NOTE: With this step, you have successfully completed the initial

conﬁguration, and your SRX345 Services Gateway is ready for use.

Change the Conﬁguration Settings (Optional)

After you complete the initial setup conﬁguration, you can access the J-Web

setup wizard by clicking Conﬁgure > Device Setup > Set Up. You can either

edit the existing settings or create a new conﬁguration. If you choose to create

a new conﬁguration, then all the current conﬁguration in the services gateway

will be deleted.

Power O the Device

You can power o the device in one of the following ways:

• Graceful shutdown—Press and immediately release the Power button.

• Forced shutdown—Press the Power button, and hold it for 10 seconds.

back on.

How to Set Up Your SRX345 Services Gateway 9

Reset the Conﬁguration

Use the RESET CONFIG button to restore the device to the factory-default

conﬁguration or to a rescue conﬁguration. To press the RESET CONFIG button,

insert a small probe (such as a straightened paper clip) into the pinhole on the

front panel.

Pressing and quickly releasing the RESET CONFIG button loads and commits

the rescue conﬁguration. The rescue conﬁguration is a previously committed,

valid conﬁguration set through J-Web or the CLI. The STATUS LED is solid amber

during this time.

Pressing and holding the RESET CONFIG button for 15 seconds or more,

until the STATUS LED is solid amber, deletes all conﬁgurations (backup

conﬁgurations and rescue conﬁguration), and loads and commits the factory

conﬁguration.

NOTE: After resetting the device, check the device status by viewing the

LEDs on the front panel. For information on the LED states, see the Power

On the Device section.
