END USER LICENSE AGREEMENT
READ THIS END USER LICENSE AGREEMENT (“AGREEMENT”) BEFORE DOWNLOADING, INSTALLING, OR USING THE SOFTWARE.
BY DOWNLOADING, INSTALLING, OR USING THE SOFTWARE OR OTHERWISE EXPRESSING YOUR AGREEMENT TO THE TERMS
CONTAINED HEREIN, YOU (AS CUSTOMER OR IF YOU ARE NOT THE CUSTOMER, AS A REPRESENTATIVE/AGENT AUTHORIZED TO
BIND THE CUSTOMER) CONSENT TO BE BOUND BY THIS AGREEMENT. IF YOU DO NOT OR CANNOT AGREE TO THE TERMS CONTAINED
HEREIN, THEN (A) DO NOT DOWNLOAD, INSTALL, OR USE THE SOFTWARE, AND (B) YOU MAY CONTACT JUNIPER NETWORKS
REGARDING LICENSE TERMS.
1. The Parties. The parties to this Agreement are (i) Juniper Networks, Inc. (if the Customer’s principal office is located in the Americas) or
Juniper Networks (Cayman) Limited (if the Customer’s principal office is located outside the Americas) (such applicable entity being referred
to herein as “Juniper”), and (ii) the person or organization that originally purchased from Juniper or an authorized Juniper reseller the applicable
license(s) for use of the Software (“Customer”) (collectively, the “Parties”).
2. The Software. In this Agreement, “Software” means the program modules and features of the Juniper or Juniper-supplied software, for
which Customer has paid the applicable license or support fees to Juniper or an authorized Juniper reseller, or which was embedded by
Juniper in equipment which Customer purchased from Juniper or an authorized Juniper reseller. “Software” also includes updates, upgrades
and new releases of such software. “Embedded Software” means Software which Juniper has embedded in or loaded onto the Juniper
equipment and any updates, upgrades, additions or replacements which are subsequently embedded in or loaded onto the equipment.
3. License Grant. Subject to payment of the applicable fees and the limitations and restrictions set forth herein, Juniper grants to Customer
a non-exclusive and non-transferable license, without right to sublicense, to use the Software, in executable form only, subject to the
following use restrictions:
a. Customer shall use Embedded Software solely as embedded in, and for execution on, Juniper equipment originally purchased by
Customer from Juniper or an authorized Juniper reseller.
b. Customer shall use the Software on a single hardware chassis having a single processing unit, or as many chassis or processing units
for which Customer has paid the applicable license fees; provided, however, with respect to the Steel-Belted Radius or Odyssey Access
Client software only, Customer shall use such Software on a single computer containing a single physical random access memory space
and containing any number of processors. Use of the Steel-Belted Radius or IMS AAA software on multiple computers or virtual machines
(e.g., Solaris zones) requires multiple licenses, regardless of whether such computers or virtualizations are physically contained on a single
chassis.
c. Product purchase documents, paper or electronic user documentation, and/or the particular licenses purchased by Customer may
specify limits to Customer’s use of the Software. Such limits may restrict use to a maximum number of seats, registered endpoints, concurrent
users, sessions, calls, connections, subscribers, clusters, nodes, realms, devices, links, ports or transactions, or require the purchase of
separate licenses to use particular features, functionalities, services, applications, operations, or capabilities, or provide throughput,
performance, configuration, bandwidth, interface, processing, temporal, or geographical limits. In addition, such limits may restrict the use
of the Software to managing certain kinds of networks or require the Software to be used only in conjunction with other specific Software.
Customer’s use of the Software shall be subject to all such limitations and purchase of all applicable licenses.
d. For any trial copy of the Software, Customer’s right to use the Software expires 30 days after download, installation or use of the
Software. Customer may operate the Software after the 30-day trial period only if Customer pays for a license to do so. Customer may not
extend or create an additional trial period by re-installing the Software after the 30-day trial period.
e. The Global Enterprise Edition of the Steel-Belted Radius software may be used by Customer only to manage access to Customer’s
enterprise network. Specifically, service provider customers are expressly prohibited from using the Global Enterprise Edition of the
Steel-Belted Radius software to support any commercial network access services.
The foregoing license is not transferable or assignable by Customer. No license is granted herein to any user who did not originally purchase
the applicable license(s) for the Software from Juniper or an authorized Juniper reseller.
4. Use Prohibitions. Notwithstanding the foregoing, the license provided herein does not permit the Customer to, and Customer agrees
not to and shall not: (a) modify, unbundle, reverse engineer, or create derivative works based on the Software; (b) make unauthorized
copies of the Software (except as necessary for backup purposes); (c) rent, sell, transfer, or grant any rights in and to any copy of the
Software, in any form, to any third party; (d) remove any proprietary notices, labels, or marks on or in any copy of the Software or any product
in which the Software is embedded; (e) distribute any copy of the Software to any third party, including as may be embedded in Juniper
equipment sold in the secondhand market; (f) use any ‘locked’ or key-restricted feature, function, service, application, operation, or capability
without first purchasing the applicable license(s) and obtaining a valid key from Juniper, even if such feature, function, service, application,
operation, or capability is enabled without a key; (g) distribute any key for the Software provided by Juniper to any third party; (h) use the
iiiCopyright © 2010, Juniper Networks, Inc.

Software in any manner that extends or is broader than the uses purchased by Customer from Juniper or an authorized Juniper reseller; (i)
use Embedded Software on non-Juniper equipment; (j) use Embedded Software (or make it available for use) on Juniper equipment that
the Customer did not originally purchase from Juniper or an authorized Juniper reseller; (k) disclose the results of testing or benchmarking
of the Software to any third party without the prior written consent of Juniper; or (l) use the Software in any manner other than as expressly
provided herein.
5. Audit. Customer shall maintain accurate records as necessary to verify compliance with this Agreement. Upon request by Juniper,
Customer shall furnish such records to Juniper and certify its compliance with this Agreement.
6. Confidentiality. The Parties agree that aspects of the Software and associated documentation are the confidential property of Juniper.
As such, Customer shall exercise all reasonable commercial efforts to maintain the Software and associated documentation in confidence,
which at a minimum includes restricting access to the Software to Customer employees and contractors having a need to use the Software
for Customer’s internal business purposes.
7. Ownership. Juniper and Juniper’s licensors, respectively, retain ownership of all right, title, and interest (including copyright) in and to
the Software, associated documentation, and all copies of the Software. Nothing in this Agreement constitutes a transfer or conveyance
of any right, title, or interest in the Software or associated documentation, or a sale of the Software, associated documentation, or copies
of the Software.
8. Warranty, Limitation of Liability, Disclaimer of Warranty. The warranty applicable to the Software shall be as set forth in the warranty
statement that accompanies the Software (the “Warranty Statement”). Nothing in this Agreement shall give rise to any obligation to support
the Software. Support services may be purchased separately. Any such support shall be governed by a separate, written support services
agreement. TO THE MAXIMUM EXTENT PERMITTED BY LAW, JUNIPER SHALL NOT BE LIABLE FOR ANY LOST PROFITS, LOSS OF DATA,
OR COSTS OR PROCUREMENT OF SUBSTITUTE GOODS OR SERVICES, OR FOR ANY SPECIAL, INDIRECT, OR CONSEQUENTIAL DAMAGES
ARISING OUT OF THIS AGREEMENT, THE SOFTWARE, OR ANY JUNIPER OR JUNIPER-SUPPLIED SOFTWARE. IN NO EVENT SHALL JUNIPER
BE LIABLE FOR DAMAGES ARISING FROM UNAUTHORIZED OR IMPROPER USE OF ANY JUNIPER OR JUNIPER-SUPPLIED SOFTWARE.

or licensors’ liability to Customer, whether in contract, tort (including negligence), breach of warranty, or otherwise, exceed the price paid
by Customer for the Software that gave rise to the claim, or if the Software is embedded in another Juniper product, the price paid by
Customer for such other product. Customer acknowledges and agrees that Juniper has set its prices and entered into this Agreement in
reliance upon the disclaimers of warranty and the limitations of liability set forth herein, that the same reflect an allocation of risk between
the Parties (including the risk that a contract remedy may fail of its essential purpose and cause consequential loss), and that the same
form an essential basis of the bargain between the Parties.
9. Termination. Any breach of this Agreement or failure by Customer to pay any applicable fees due shall result in automatic termination
of the license granted herein. Upon such termination, Customer shall destroy or return to Juniper all copies of the Software and related
documentation in Customer’s possession or control.
10. Taxes. All license fees payable under this agreement are exclusive of tax. Customer shall be responsible for paying Taxes arising from
the purchase of the license, or importation or use of the Software. If applicable, valid exemption documentation for each taxing jurisdiction

•Understanding How Junos Space Uses Ethernet Interfaces eth0 and eth3 on page 9
Junos Space Virtual Appliance Overview
The Junos Space Virtual Appliance consists of preconfigured Junos Space software with
a built-in operating system and application stack that is easy to deploy, manage, and
maintain.
A Junos Space Virtual Appliance includes the same software and all the functionality
available in a Junos Space physical appliance. However, you must deploy the virtual
appliance on the VMware ESX or ESXi Server, which provides a CPU, hard disk, RAM, and
a network controller, but requires installation of an operating system and applications
to become fully functional.
Just as you can install additional physical appliances to create a fabric to provide
scalability and availability, you can deploy multiple virtual appliances to create a fabric
that provides the same scalability and high availability as a fabric of physical appliances.
You can create a fabric of JA1500 Junos Space appliances, Junos Space virtual appliances,
or a hybrid fabric of both physical and virtual appliances.
Understanding How Nodes Are Connected in a Fabric
Each Junos Space appliance (physical or virtual) that you install and configure is
represented as a single node in the fabric. You can add nodes without disrupting the
services that are running on the fabric. When you install and configure the first appliance,
Junos Space automatically creates a fabric with one node. For each additional appliance
you install and configure, you must add a node to logically represent the appliance in the
fabric. You add nodes to the fabric from the Administration workspace in the Junos Space
user interface. Each node that you add to the fabric increases the resource pool for the
node functions to meet the scalability and availability requirements of your network. By
default, Junos Space automatically enables node functionality across the nodes in the
fabric to distribute workload. The nodes in the fabric work together to provide a virtualized
resource pool for each of the node functions: load balancer, database, and application
logic.
3Copyright © 2010, Juniper Networks, Inc.

In a fabric comprising two or more nodes, Junos Space provides failover when a node
functioning as the active server (load balancer server or database server) goes down. By
default, Junos Space marks a particular node down and routes failover requests to the
node that Junos Space designates as standby server. Junos Space uses a heartbeat
mechanism to check whether the nodes in the fabric are running. When a node functioning
as the active server fails (the appliance crashes or stops sending heartbeats), the node
functioning as the standby server takes over all resources that were managed by the
node functioning as active server. Nodes in a Junos Space fabric rely on IP multicast
messages to discover each other, therefore ensure that IP multicast packets are reachable
between all nodes.
To add, manage, and monitor the nodes in the fabric, a Junos Space user connects to a
single Web IP address. The IP address of first (active) node and second (standby) node,
and the Web (virtual) IP address must all be in the same subnet. The Web IP needs to
work on both the first and second node in the fabric. When both nodes are in same subnet,
and the first (active) node goes down, the second (standby) node becomes the active
node and packets continue to be directed from the router, to the Junos Space Web IP,
and then to the second node, because both nodes are in same subnet. However, if the
second (standby) node is configured in a different subnet than the first (active) node,
and the first node goes down, the second node becomes the active node, but because
the Web IP now points to the different subnet of the second node, all packets originally
destined for first node won’t be received by the second node.
Virtual Appliance Deployment
The Junos Space Virtual Appliance is stored in the Open Virtualization Format (OVF) 1.0
and is packaged as an *.ovf file, which is a tar file that contains all the files of the Junos
Space Virtual Appliance. OVF is not a bootable format, and you must deploy each Junos
Space Virtual Appliance to a hosted ESX or ESXi server before you can run the Junos
Space Virtual Appliance.
You can deploy a Junos Space Virtual Appliance on a VMware ESX server, version 3.5. or
higher, or ESXi version 4.0 or higher to convert the Junos Space Virtual Appliance to a
virtual machine. After the Junos Space Virtual Appliance is converted to a virtual machine,
you use the VMware vSphere client that is connected to the VMware ESX (or ESXi) Server
to deploy the Junos Space Virtual Appliance on the server.
NOTE: Where the Junos Space Virtual Appliance documentation references
“ESX server” you can use either the ESX server Version 3.5 or later, or ESXi
server, Version 4.0 or later.
Recommendations for Deploying Virtual Appliances on the VMware ESX Server
The CPU, RAM, and disk space provided by the VMware ESX server must meet or exceed
the documented CPU, RAM, and disk space requirements for deploying a Junos Space
Virtual Appliance. In addition, Juniper recommends that, for a multi-node fabric, you
deploy the first and second virtual appliance on separate VMware ESX servers to ensure
failover support.

Junos Space Virtual Appliance Installation Guide

The distributed Junos Space Virtual Appliance files are created with 5 GB of disk space,
and you add an additional 40GB of disk resources when you first deploy the virtual
appliance to a VMware ESX server. In many cases, the 45 GB of disk space will be
sufficient; however, if the percent of Junos Space disk resources utilized reaches 80%
capacity, Juniper recommends that you add another 40 GB of disk space to your virtual
appliance. You can monitor the percent of disk space utilized in the Fabric Monitor
inventory panel in the Junos Space user interface.
Configuring an NTP Time Source For Each Appliance
To ensure consistent behavior among all nodes in a multi-node fabric, each node’s time
must be synchronized with every other node in the fabric. When you configure the first
Junos Space Virtual Appliance (and JA1500 Junos Space Appliance) with an NTP server,
you ensure that, if the first node (which is used to synchronize time for all nodes in the
fabric) goes down, all other nodes in the fabric remain synchronized. Additional nodes
installed into the same fabric will automatically get their time setting from the first node
in the fabric without any additional NTP server configuration.
NOTE: By default, Junos Space translates time so that the time displayed in
the user interface corresponds to Junos Space server time, but the time is
mapped to the local time zone of your client computer.
To ensure time remains synchronized across all nodes in the fabric, Juniper strongly
recommends that you add an NTP server to the first appliance (physical or virtual) during
initial set up.
NOTE: You must add the NTP server before you add the appliance/node to
the fabric from the Junos Space user interface.
Fabric Management Overview
You can deploy Junos Space appliances to create a fabric that provides the scalability
and availability that your managed network requires as you add more devices, services,
and users.
A Junos Space fabric comprises one or more IP-connected nodes. A node is a logical
object that represents a single JA1500 Junos Space Appliance or Junos Space Virtual
Appliance, its operating system, and the Junos Space software that runs on the operating
system. Each Junos Space appliance or virtual appliance that you install and configure
is represented as a single node in the fabric. You can add nodes without disrupting the
services that are running on the fabric. When you add nodes to the fabric, you can manage
and monitor the nodes from the Administration workspace. To add, manage, and monitor
nodes in the fabric, a fabric administrator connects to a single virtual IP address, as shown
in the illustration.

Chapter 1: Installation Overview

NOTE: All appliances (nodes) in a fabric must be from same Junos Space
release. For example, a fabric comprises Junos Space Release 1.4 appliances
or Junos Space Release 2.0 appliances, but not both.
Single Node Functionality
When the fabric comprises a single appliance, all devices in the managed network connect
to the appliance. When you install and configure the first appliance, Junos Space
automatically creates a fabric with one node. By default, a fabric that consists of a single
node provides complete Junos Space management functionality, with the following node
functions enabled for the node:
•Load Balancer— for processing HTTP requests from remote browsers and NBI clients
•Database— for processing database requests (create, read, update, and delete
operations)
•Application Logic— for processing back-end business logic (Junos Space service
requests) and DML workload (device connectivity, device events, and logging)
NOTE: A fabric that comprises a single node provides no workload balancing
and no backup if the appliance goes down.
