Network Application Platform

The Junos Space Network Application Platform provides the essential tools the network

administrator needs for automating network operations, including device discovery and

management, topology visualization, deploying device images, job operation management,

user account management, audit logging, and network administration. Network

administration tasks include managing the Junos Space fabric (comprising one or more

IP-connected nodes), database, licenses, applications, upgrades, tags, and

troubleshooting.

New Features

The Junos Space Network Application Platform includes the following new features:

•(Administration) Junos Space 2.0 Upgrade—The Junos Space 2.0 software is bundled

with Service Now and Service Insight. Junos Space 2.0 Hot-pluggable applications

include:

•Ethernet Design

•Network Activate

•QoS Design

•Security Design

•Virtual Control

To upgrade to the Junos Space version 2.0 software from version 1.3 or 1.4, use the

Platform > Administration > Manage Applications Upgrade Platform action.

•(Scripts) Compare Script Versions—Junos Space enables you to compare two scripts

and view the differences in their content. You can compare two different scripts or two

versions of the same script. Different colors are used to indicate differences between

the compared scripts.

•(Scripts) Automatic selection of the latest scripts—Junos Space automatically picks

the latest version of a script for deploying, verifying, enabling, disabling, and executing

a script on devices. While the Manage Scripts page displays multiple versions of the

same script, only the latest version of the script is picked even when you select an older

version of the script.

•(Devices) Support for WW Junos OS Devices—The Junos Space wwadapter lets you

use Junos Space to manage devices running the world wide version of Junos OS. These

devices use Telnet protocol instead of Secure Shell protocol (SSHv2) for

communication. The wwadapter acts as a medium between Junos Space and the

device.

•(Devices) Connecting to Device Discovery Target Using Telnet—Junos Space connects

to devices running worldwide Junos OS with the Connect via Telnet option on the

Discover Target page.

•[Release Candidate Test Quality] (Device Templates) Device Templates—Device

templates let you remotely deploy and update the JUNOS OS configuration running

Junos Space 2.0 Release Notes

on multiple devices on your network. Device template creation involves two major

tasks:

•Creating and publishing a template definition based on configuration options for a

Juniper Networks Junos OS device family DMI schema and device specific values.

•Creating, validating, and deploying a device template based on a template definition

instance.

The network designer creates the template definition and assigns the network operator

to deploy the template.

•(Users) Create User-Defined Role—Add one or more application workspace tasks per

user-defined role using Platform > Users > Manage Roles > Create Role.

•(Administration) Different Back Up Database Location—The database back up

location has changed from var/lib/mysql/backup to /var/cache/jboss/backup. To back

up the Junos Space database, use Platform > Manage Databases > Backup Database.

•Administration) Configure New Application Settings—Use the Platform >

Administration > Manage Applications > Modify Application Settings action to configure

the following setting. The look and feel of the Application Settings page has changed

to a paged design instead of a dialog box.

•Allow users to auto log in to devices using SSH—Allows users to automatically log in

when starting an SSH connection on a device. The default, not selected, indicates

that you have to add your credentials to log in to a device using SSH.

•Junos Space initiates connection to device—Specifies connections between Junos

Space and managed devices. If selected, Junos Space initiate connection with devices

instead of the default behavior of device initiating connection.

•SSH port 22 for device connection—Specifies the SSH port on the device. Junos Space

uses this port to discover devices. The default value, 22, is the standard SSH server

port.

•(Administration Network Activate Application Settings—Using the Platform >

Administration > Manage Applications Modify Application Settings action, you can

modify Network Activate application settings.

•(Administration) Shutdown or Reboot a Fabric Node—From Junos Space, the super

administrator or system administrator can shut down or reboot fabric nodes (appliances

or virtual machine hosts) when moved or network settings reconfigured. Use the

Platform > Administration > Manage Fabric > Shut Down Node action. You can also

type an optional message for administrators logged in to an affected node.

•(Administration) Changing Node Network Settings—Using Platform > Administration

> Manage Fabric > Network Settings, you can change the following network settings:

•VIP

•Management IP, subnet mask and default gateway

•Change, add or delete device management IP, subnet mask and default gateway

Nodes require restart to apply new network settings.

Network Application Platform

Known Issues

The following issues are known in Junos Space release 2.0:

•If you modify the device management interface gateway from \ JMP_SETUP > -2(set

routing), the Network Setting still display the old Value. It displays the correct IP value

after you reboot the node. (PR 59885)

•Dynamic notification does not work for Service Now customers with Partner License.

It works only for connected member in the Organization inventory page. (PR 526175)

•The Platform > Manage Applications upload process does not display an error message

if it is interrupted. (PR 545034)

•The SSH connection state between Junos Space and a device still exists after automatic

logout of the system occurs for an idle user. (PR 554372)

•On the Administration > Manage Fabric inventory page in tabular view, the cursor focus

in the Console Message text box disappears and the text you are typing is not displayed

if you type continuously in Console Message text box for approximately 20 seconds.

Click in the Console Message text box to continue typing. (PR 551594)

•For a Junos Space initiated connection, the Platform > Manage Devices inventory page

fails to switch to the new master Routing Engine on the dual Routing Engine on a JUNOS

OS device. (PR 563648)

•Modifying a custom role sometimes does not show the task tree. Click Cancel, then

modify the role again. (PR 564018)

•When you add a new node to a prime node fabric to which an upgraded version of WW

Junos OS adapter has already been deployed, Junos Space does not automatically

deploy the adapter to the new node. As a workaround, delete the adapter from the

prime node before you add a new node to the fabric. After you add the new node, you

can deploy the WW Junos OS adapter to both the nodes on the fabric. (PR 565798])

•(Device Templates RCT Version) The template validation/deployment error messages

are ambiguous and will be improved. (PR 564379)

•(Device Templates RCT Version) When you create a template definition, do not enter

a lengthy description for a table or its label field. If the description occupies 3 or more

lines of the Specify Default Values for Configuration Parameters page header, any

message triggered by your input on that page would be below the visible part of the

screen, for example the “Do you want to save this draft before you leave this page?”

message that requires clicking a Yes or a No button. (PR 564751)

•(Device Templates RCT Version) Search results are under construction and will be

improved. (PR 564769)

•(Device Templates RCT Version) When creating a template definition with an option

of the ’choice’ data type, be sure to complete all your settings on the tabs and click

Next before you go on to another Configuration page in the Selected Configuration

Layout panel. If you need to return to another page, click Back. (PR 565072)

Junos Space 2.0 Release Notes

•(Device Templates RCT Version) When you enter a term in the Search field, hitting

Enter will not take you to the next occurrences of the term in the Available Configuration

options list. (PR 565665)

•(Device Templates RCT Version) When creating a template definition and using the

Search function, you cannot enter same search text sequentially (PR 565744)

•(Device Templates RCT Version) Do not leave the user interface idle for more than 19

minutes. (PR 564461)

Network Activate

Junos Space Network Activate software enables you to provision point-to-point and

multipoint services across networks. You provision point-to-point services across networks

that use LDP for signaling in the network core. These services use directed pseudowire

virtual circuits across the network to establish point-to-point virtual private networks

(VPNs). You provision multipoint services across networks that use BGP signaling in the

network core. These VPLS services use route targets and route distinguishers to establish

service connectivity. The Network Activate software supports multipoint-to-multipoint

(full mesh) services and point-to-multipoint (hub and spoke) services.

New Features

The Network Activate application supports the following new features:

•Aggregated Ethernet interfaces—UNI interfaces for prestaged PE devices can be

aggregated Ethernet (ae) interfaces.

•Fast Ethernet interfaces—UNI interfaces for prestaged PE devices can be Fast Ethernet

(fe) interfaces. Fast Ethernet (fe) interface support is limited to specific Ethernet

service configurations (on M Series devices with Junos 10.2R1.6). See “Prestaging

Devices Overview” in the Network Activate user documentation for more information.

•Force Deploying a Service—When a service fails a configuration audit because

configuration changes on a PE device do not match the configuration required for the

service, you can force deploy the service to push the configuration to the device. Force

Deployment pushes the same configuration to the device that was pushed during the

deployment of the service, thus allowing the operator to recover from a state in which

the configuration on the device was lost or changed out-of-band.

•Multihomed groups—Create one or more multihomed groups to connect a customer

site to multiple N-PE routers to provide redundant connectivity across a VPLS site

while preventing the formation of Layer 2 loops in the service provider’s network. A

VPLS site multihomed to two or more N-PE routers provides redundant connectivity

in the event of a PE-router-to-CE-device link failure or the failure of an N-PE router.

•QoS-enabled Ethernet services—Attach a QoS profile to a point-to-point or multipoint

(VPLS) service to define levels of service for UNI ingress and UNI egress traffic at the

provider edge.

•Services with flexible VLAN tagging—Specify the asymmetric tag height Ethernet

option to enable flexible VLAN tagging on VPLS services. A service with flexible VLAN

tagging allows transport of Ethernet frames between UNI endpoints with mixed

Network Activate

interface types (port, 802.1Q, and Q-in-Q). For example, a service normalized to 802.1Q

that specifies port, 802.1Q, and Q-in-Q UNI endpoints performs the necessary pop,

swap, or push operations to manipulate (inner and outer) VLAN tags to transport

single-tagged frames across the UNI endpoints.

•Enhancements to Normalization option—Configure an Ethernet service with a specified

interface type to transport frames with a different tag height. For example, you can

create Layer 2 VPN Q-in-Q to Q-in-Q service that transports single-tagged frames or

a Layer 2 VPN 802.1Q to 802.1Q service that transports double-tagged frames.

Network Activate Release 2.0 Issues

The Network Activate 2.0 release includes the following known issues:

•An AE interface that specifies one or more logical interfaces with assigned IP addresses

is not a candidate for UNI role assignment. [562759]

•A Functional Audit might show incomplete information in the Functional Audit result

window. [559092]

•Functional Audit might fail when you modify a service order by changing the role of an

N-PE device in a multihomed group from primary to secondary and then deploy the

service order, if the VPLS service definition specifies

"Asymmetric_Vlan_Range_Normalize_to_vlan_all" with Advanced option, and auto-pick

enabled. [565249]

QoS Design

The QoS Design application allows you to configure Quality of Service (QoS) features

to provide improved service to certain network traffic on Ethernet services. Enabling QoS

on an Ethernet service can improve network service by providing dedicated bandwidth,

setting traffic priorities across the network, improving loss characteristics, shaping network

traffic, and managing network congestion.

New Features

Create a QoS profile to configure classification and policing for UNI ingress traffic and

policing, scheduling and shaping for UNI egress traffic on Ethernet services. The QoS

Design application includes the following workspaces that allow you to define levels of

service that you can then apply to Ethernet services in the Network Activate application:

•QoS Domains—Prestage QoS to partition your network into domains. A domain

represents a group of N-PE routers for which the QoS treatment on the uplink interfaces

is the same or similar. You can perform a single domain discovery operation to discover

all the QoS domains on your network. Each QoS domain includes only those N-PE

routers that share the exact rewrite rules and classifiers. If the scheduler maps are

different, they are grouped in the domain as separate scheduler maps.

•Drop Profiles—Define parameters that allow packets to be dropped from the network.

Drop profiles define the meanings of the loss priorities. When the number of packets

queued is greater than the ability of the router to empty a queue, the queue requires a

method for determining which packets to drop from the network.

Junos Space 2.0 Release Notes

•QoS Schedulers—A QoS scheduler defines the output queue properties for each class

of service in the domain that is associated with the scheduler. Queue properties include

the amount of interface bandwidth assigned to the queue, the size of the memory

buffer allocated for storing packets, the priority of the queue, and the random early

detection (RED) drop profiles associated with the queue. The QoS Design software

supports two-level and three-level schedulers A two-level scheduler is a shared

scheduler (or scheduler profile) that allows logical interfaces belonging to the same

physical port to share one set of scheduling properties. A two-level scheduler can also

include a drop profile to reference WRED congestion control of the queue. With a

three-level scheduler, scheduling is performed at the interface level and the scheduler

defines two parameters—the port oversubscription ratio and the interface

oversubscription ratio.

•QoS Profiles—A QoS profile is a configuration template that allows you to create

service offerings that provide priority to certain traffic when you provision Layer 2

Ethernet Services. A QoS profile defines classification and policing for UNI ingress

traffic and policing, scheduling, and rewrite rules for UNI egress traffic on the N-PE

devices for Ethernet services.

Known Issues

The QoS Design 2.0 release includes the following known issues:

•Create scheduler issue when you deselect a class of service. If you clear the check box

for some CoS rows and then edit one or more selected CoS rows, when you click OK

the edited CoS rows that you configured are preserved. However, the CoS rows that

were cleared before you clicked OK are automatically selected again. As a workaround,

clear the checkbox for each CoS row that was automatically selected and then click

Create. Only the Cos rows you intentionally selected are saved for the QoS scheduler.

[565752]

Security Design

The Junos Space Security Design application is a powerful but easy-to-use solution that

allows you to design a security topology that represents your physical network, create

IPSec VPNs on different sections of your network to provide appropriate security on the

network, and create security policies that define a set of rules to permit, deny or reject

communication between security domains.

New Features

The Junos Space Security Design application presents the following new features:

•CLI Preview for Provisioning IPSec VPNs and Security Policies—The provisioning

workflow for IPSec VPNs and security policies allows you to view the CLI format of the

configuration pushed to the device.

•Support for Screen OS Devices— Screen OS devices are supported in IPsec VPN and

Security Policy creation and deployment.

Security Design

•Policy VPN Integration— When a security policy created between two security domains

is provisioned, the policy will use the paths defined by the IPSec VPN created between

the security devices associated with the security domains.

•Security Policy for Intermediate Firewall— An intermediate firewall with the security

policy which allows IKE/IPsec traffic for VPN is configured automatically when

provisioning a VPN with an intermediate firewall. The intermediate device is listed

along with the VPN endpoints.

•NAT— Create, manage and provision NAT policies to devices. Using Network Address

Translation (NAT), you can maintain network security by hiding internal IP addresses

from other networks. You can also use NAT to conserve IP addresses. Junos Space

supports two types of NAT:

•Source NAT— Translates the source address of outbound traffic.

•Static NAT— Maintains a constant one-to-one address translation. It translates the

same private address to the same public address.

Known Issues

•If you create a device group with more than 100 devices, the device group will not be

visible on the topology whiteboard.

Workaround: Click on the topology whiteboard. [PR 563375]

•When you decommission a VPN that has VPN Monitor setting enabled, VPN Monitor

options such as Interval and Threshold are not removed from the device.

Workaround: Manually remove the VPN Monitor options using the CLI interface.

[PR 546065]

•If you create and configure a group link that has a large number of devices, the Link

Properties window will still show that the group link is not configured. If you delete a

group link that has a large number of devices, the link is still displayed on the topology

whiteboard.

Workaround: Click on the topology whiteboard. [PR 561740]

Junos Space 2.0 Release Notes

Resolved Issues

•If you create two Provisioning Jobs to simultaneously provision two VPNs that use a

common set of security devices, only the first Provisioning Job will succeed. The second

Provisioning Job fails and displays an incorrect error message.

Workaround: You can either re-provision the second VPN that failed to provision after

the first VPN’s Provisioning Job is complete, or provision these VPNs, one at a time,

ensuring that the first VPN’s Provisioning Job is complete before you start provisioning

the next one. [PR 544595]

Service Insight

The Junos Space Service Insight application accelerates operational analysis and manages

exposure to known issues. The Junos Space Service Insight application presents the

following new features:

New Features

The Junos Space Service Insight application presents the following new features:

•Automated EOL analysis—Identifying the devices available for End Of Life (EOL)

reports and providing EOL information for those devices by enabling generation of EOL

reports that provide detailed device EOL information, such as, the number of devices

in the network with EOL parts, EOL announce date, number of EOL announce parts,

End Of Engineering SW date, number of End Of Engineering SW parts, End Of

Engineering HW date, number of End Of Engineering HW parts, End Of Support date,

number of End Of Support parts, top level assembly parts, circuit assembly parts, PSN

numbers, and replacement numbers. This helps ensure that software and devices are

serviceable and you can upgrade and replace equipment that is no longer supported

by Juniper Networks.

•PBNs for preventive action— Identifying devices with characteristics similar to devices

on which issues were found and displaying Proactive Bug Notifications (PBNs) that

provide information about issues, such as, the condition that triggered the issue,

symptoms of the issue, temporary solutions to the issue, and additional instructions

that users can follow to prevent the issue from occurring on the device. This is a

proactive measure to ensure that users are aware of the known issues that could affect

their network. Users can scan PBNs to display only those devices that are affected by

a particular PBN, flag PBNs to users, assign owners to the PBNs, e-mail the PBNs to

users, and delete them. Users can also list the PBNs that are associated to a particular

device.

•Notifications— Notifying users about EOL and PBN information arrival and PBN

information matches found for devices on the network. Managing these notifications

and also creating filters that further specify when users must be notified, such as, the

tag value that must match for the associated devices, the serial number or device

name that must be matched, and the words that must or must not match the title of

the PBN that has arrived. Users are allowed to edit notifications, enable or disable

them, copy the attributes of notifications, and delete notifications.

Service Insight

Service Now

The Junos Space Service Now application streamlines fault management for JUNOS

devices by automating the detection, isolation and resolution of network faults and

incidents.

New Features

The Junos Space Service Now application presents the following new feature:

•Installing AI-Scripts on Devices with Dual REs—When you install AI-Scripts on devices

with dual REs, Service Now installs AI-Scripts on both the primary and backup routing

engines. After the AI-Scripts are installed, the Manage Jobs page and the Service Now

Device Details dialog box display the status of installation for the individual REs (primary

and backup).

Known Issues

•The connected members displayed on the Manage Organizations page will not receive

dynamic notifications when Service Now operates in the partner proxy mode.

[PR/526175]

•Junos OS devices may not provide specific time zones for incidents, and hence Service

Now may display an incorrect time of occurrence for incidents. For example, when the

time zone is EST, Service Now uses US EST by default, while the time zone can also

be AEST (Australian EST). [PR/544087]

•The connection between the Service Now partner proxy and its end customers fails

when a user changes the IP address of a Service Now partner proxy.

Workaround: Manually update the IP address of the Service Now partner proxy in your

Service Now application. [PR/564827]

•Service Now cannot uninstall AI-Scripts from the back up RE of a device with dual REs.

[PR/555657]

Virtual Control

New Features

This release of Junos Space Virtual Control presents the following new features:

•Virtual Machine List— View the list of virtual machines and their respective virtual NICs

from the vNetwork workspace.

•Block Virtual Ports— Block and unblock virtual ports from Virtual Switch view.

•Purging of Configuration Audit Results — Purge configuration audit reports available

from vNetwork view either by its age or count.

•Cluster Support— The JSVC will now work in a Cluster setup (JA Fabric setup).
