JUNIPER Space Network Director

Quick Start Guide

Junos Space Network Director can be used for campus network management. On campus, Network Director automates routine management tasks such as network provisioning and troubleshooting, dramatically improving operational efficiency and reliability. Campus networks have increased variability and unpredictability stemming from a wide range of user and IoT devices. Juniper’s portfolio of services, software, and hardware products securely addresses end- to-end campus network solutions. Junos Space Network Director enables unified management of EX Series Ethernet Switches, MX Series routers, QFX Series switches, and Junos Fusion Enterprise in your network. It provides for full network life cycle management by simplifying the discovery, configuration, visualization, monitoring, and administration of large networks containing physical and virtual devices. This chapter describes how you can install Network Director, upgrade Network Director, and bring your devices under Network Director management. These installation steps are intended for network operators and administrators who install, configure, and manage Junos switching with EX Series, QFX Series, and virtualized devices using Network Director. Before you install Network Director, you must configure the Junos Space Appliance as a Junos Space node. You can install Network Director in Junos Space Virtual Appliance. For details, see “Setting up a Junos Space Appliance for Network Director”

Setting up a Junos Space Appliance for Network Director

IN THIS SECTION

• Junos Space Virtual Appliance

You can install Network Director in one of the following appliances

• “Junos Space Virtual Appliance”

Junos Space Virtual Appliance

The Junos Space Virtual Appliance consists of preconfigured Junos Space Network Management Platform 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 provides all the functionality available in a Junos Space physical appliance. However, you must deploy the virtual appliance on the VMware ESX or ESXi server, or Kernel-based virtual machine (KVM) which provides a CPU, hard disk, RAM, and a network controller, but requires installation of an operating system and applications to become fully functional. For information about installing Junos Space appliances in a fabric configuration and installing Junos Space Virtual Appliance on a VMware ESX or ESXi server, see Junos Space Virtual Appliance.

Uploading DMI Schemas

Junos Space Network Management Platform interfaces with network devices using an open API called the Device Management Interface (DMI), which is a standard interface used by Juniper Networks devices. Each device type is described by a unique data model (DM) that contains all the configuration data of the device. The DMI schema lists all the possible fields and attributes for a type of device. The newer schemas describe the new features coming out with recent device releases. It is important that you load all your device schemas into Junos Space Network Management Platform; otherwise only a default schema is applied when you try to edit a device configuration by using the device configuration edit action in the Devices workspace. Typically, when you perform a clean installation of Junos Space Platform, a schema (usually the latest one) is automatically set as the default for each device family. If an exact matching schema is not available, the default schema for the device family is used. For the list of DMI schema that you can obtain and upload in Junos Space before you start working on Network Director 6.2R1 Release, see Junos Space DMI Schema Requirements for Network Director. If you cannot find the schema equivalent, use the latest DMI schema from the main release or contact Juniper Support. For example, for an EX4500 switch running Junos OS Release 13.2X51-D20, you must use the Junos OS Release 13.2X51-D20 schema. If this is not available, you can use the latest schema available from the Junos OS Release 13.2X51 releases. You can download the schema from Schema Repository. To install or update a DMI schema on Junos Space Platform, see Adding Missing DMI Schemas or Updating Outdated DMI Schemas by Using the Update Schema Menu.

Next Steps

After your devices are up and synchronized, much of the function in Network Director is automatically enabled. However, there are a few additional tasks that you will need to perform to use all the features of the Network Director. We suggest that you explore:

Set up a Location View
Location View is one of seven different views, or perspectives, in your network. In Location View, you can manage devices based on a site. Here you define the buildings, floors, wiring closets, and outdoor areas. You can upload floor maps for easy reference and assign devices to a specific spot. To set up a Location View:

1. Click Build in the Network Director banner.
2. Select Location View in the View pane to the left of the screen.
3. Click Setup Locations in the Tasks pane to start setting up your location, buildings, floors, racks, wiring closets, and outdoor areas.

Enable Trap Forwarding and Alarms for Fault Management
A key component of the Network Director is to diagnose problems with precision and ease. Network Director correlates multiple traps from the same device to a single alarm.
You must complete device discovery and the devices must be up before you can enable trap forwarding. Traps are not enabled by default; you need to enable them after device discovery.

1. Use Set SNMP Trap Configuration in the Tasks pane of Deploy mode to configure your device to send SNMP traps to Network Director.
2. Review the list of alarms in Preferences, located in the Network Director banner. All alarms are enabled by default, but you might want to disable those alarms that are not pertinent to your installation. You can also change the severity of an alarm by using Preferences.

Set up users
After you install Network Director, there is only one username defined: super with the default password, juniper123.
You have the ability to set up users with different Network Director privileges. New Network Director users are set up in Junos Space and follow the roles and privileges as defined in Junos Space. For a complete discussion on how to properly set up users, see Understanding Network, Director User Administration.

• Configure Network Director API—The Network Director API is a set of Representational State Transfer (REST) APIs that enable network management functions and is installed when you install Network Director. To know more about configuring Network Director API, see Network Director API Guide.

• Learn what you can do with Network Director
  There are two ways you can become familiar with the functions and features of the Network Director:

• Use the extensive online help system that guides you through Network Director. Clicking the main Help icon provides a top-down view into the help system; clicking a Help icon on a pane or window provides context-sensitive information. Use the help system to familiarize yourself with Network Director and the different modes and panes in the interface.

• Refer to the Network Director User Guide.

Preparing Devices for Management by Network Director

To discover and manage devices, Network Director requires the following minimum device configuration as a prerequisite. Ensure that the device:

• Has a static management IP address. The address can be in-band or out-of-band but must be reachable from the Junos Space server.

• Is enabled for SSH v2. On EX Series switches you need to enable SSH. Issue the set system services ssh protocol-version v2 command to enable SSH v2 on EX Series switches.

• Has a user ID with the superuser class been configured? Junos Space and Network Director use this user ID to authenticate the SSH connection with the device.

• Is enabled for SNMP with the appropriate read-only V1, V2, and V3 credentials created. You do not need to configure SNMP trap receivers; Network Director configures traps as a deployment task. In addition, the following protocol ports must be open for the Network Director’s communication

• Port 22 for SSH connections. If you have changed the SSH port to a port other than port 22 on your Network Management Platform, you must change the SSH ports on your managed devices to the port that the Network Management Platform is using.

• Port 10162 for SNMP traps. Network Director receives traps from managed devices on this port.
  (After you install Network Director, use Network Director to configure SNMP on your devices to send traps to Network Director on this port.)

• Port 21 (TCP) and port 69 (UDP) for uploading the software image and configuration file to the FTP server.

Discovering Devices

When you start Network Director for the first time, the system does not have any devices. The first step is to build your network. Even with large networks, Network Director has made this step relatively easy and straightforward. You will add devices to Network Director and the database by using a process called device discovery. Once a device is discovered, it shows in the interface and Network Director begins to monitor the device. Network Director provides a wizard for device discovery. The following example shows the path for device discovery through the wizard. For an alternate path, you can get step-by-step instructions from the help system. In this example, we provide an IP address range, and Network Director populates the database with all supported devices within that range.

1. While in the Build mode, select Logical View, Location View, Device View, or Custom Group View from the View selector.

2. To discover physical devices, click Discover Devices in the Tasks pane. Each mode has a Tasks Pane that displays the actions you can take while in that mode and that particular network view.

3. (Optional) Type a name for the discovery job. The default name is ND Discovery.

4. Click Add in the Device Targets window. You can add a single device IP address, a range of IP addresses, an IP subnet, or a hostname. In this example, we select an IP address range.

5. Provide the initial or the lowest IP address value and the ending or highest IP address value for the range and click Add. You can have up to 1024 devices in a range. After you click Add, the address range is listed in the Device Targets window.

6. Click Next or click Discovery Options to proceed to specify the device credentials and method of discovery.

7. Click Add in the Device Credentials window and enter the username and password assigned for administrative access.

8. Select Ping, SNMP, or both as the method of device discovery. Selecting both is the preferred method if the device is configured for SNMP.
   If you select SNMP, the Add SNMP Settings dialog box is displayed. In this example, because we run SNMP version 2, we need to provide the community string. Click Add to save the setting.
   NOTE: You cannot choose a method for device discovery for virtual network discovery.

9. Click Next or Schedule Options to proceed to schedule the time when discovery is run.
   NOTE: Scheduling options are not available for virtual network discovery.

10. Indicate whether to run the device discovery now or set up a schedule to minimize network traffic. In this example, we set the schedule to run during off hours.

11. Click Review to review the settings before you exit the wizard.

12. Click Finish to complete the discovery setup and to save the settings.

13. Click View Discovery Status to view all scheduled and completed jobs. After a job completes, you can click Show Details to view further information on any unexpected results.
