Build Your Network
The first step after you install and log in to Network Director is to build your network. Even with large networks, Network Director has made this step relatively easy and straightforward. The steps that you need to perform depend on whether your network contains legacy devices, or new devices, or a combination of both.
You add legacy devices, which already have some configurations, to Network Director by using a process called device discovery. Once such a device is successfully discovered, Network Director reads the device configurations and replicates these configurations in the form of profiles in Network Director. You can use device discovery to add Juniper Networks switches and Wireless LAN Controllers (WLCs) to Network Director. For more details, see Brownfield Deployment in Network Director.
With new devices or devices that are set to factory-default configuration, you can use the zero touch provisioning (ZTP) feature to provision the device. ZTP enables you to auto-discover, auto-upgrade, and load the requisite default configuration on Juniper Networks switches in your network automatically—without manual intervention. When you physically connect a switch that has the factory-default configuration to a network and boot the switch, the switch attempts to upgrade Junos OS automatically and autoinstall a configuration file from the network.
Discovering Devices
The first step to manage your existing network devices using Network Director is to discover these devices from Network Director. You can discover devices from Network Director using an easy-to-use wizard-based workflow.
To discover devices in Network Director:
- Log in to Network Director.
Network Director user interface opens with Dashboard View selected.
- Select Logical View from the View selector in the Network Director banner to open the Logical View.
- Click Discover Devices from the Device Discovery
menu in the Tasks pane.
The Discovery Devices wizard opens.
- Do one of the following:
- 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.
- To add devices in bulk, click Import from CSV and select a CSV file that has details about the devices that you want to add to Network Director. You can download a sample CSV to understand the format of the CSV file by clicking CSV Sample.
- Click Next and then click Add in the Device Credentials table to add the device credentials.
- Specify the device administrator username and password for the device that you want to discover, and confirm the password. The username and password must match the name and password configured on the device that is to be discovered.
- Click Add to save the username and password that you specified or click Add More to add another username and password. Click Add after you have finished adding all login credentials. The Device Credentials table displays the usernames that you configured.
- In the Specify Probes section, select both the Use Ping and the Use SNMP check boxes to enable Network Director for faster discovery of the target devices, provided the device is pingable and also SNMP is enabled on the device. Specify the SNMP settings and click Next.
- Do one of the following:
- Click Run Now to discover the devices immediately.
- Use the scheduling option if you want the discovery job to be run at a later time.
Click Next to review the discovery options.
- Click Finish. If you chose to discover the
devices immediately, Network Director starts the discovery process.
A message window opens, displaying the status of the device discovery job name and job ID. Click OK.
The Device Discovery Jobs page opens, displaying a list of scheduled jobs.
Adding Devices Using Zero Touch Provisioning
Zero touch provisioning (ZTP) simplifies the deployment of networks without requiring user intervention, providing policy-driven plug-and-play provisioning and network bring-up operations for both fabrics and individual devices.
To add devices using ZTP, follow the steps mentioned here or watch this video-based tutorial:
Video 1: Zero Touch Provisioning using Network Director
Before you begin:
Ensure that the switch has access to the following network resources:
- The DHCP server that provides the location of the software
image and configuration files on the network
See your DHCP server documentation for configuration instructions.
- The anonymous FTP server, the HTTP server, or the Trivial
File Transfer Protocol (TFTP) server on which the software image and
configuration files are stored. If you are using an FTP server, ensure
that the FTP server is configured to enable anonymous access. Refer
to your FTP server documentation to know more about this.
Note: Although TFTP is supported, we recommend that you use FTP or HTTP, because these transport protocols are more reliable.
- (Optional) A Network Time Protocol (NTP) server to perform time synchronization on the network.
- (Optional) A system log (syslog) server to manage system log messages and alerts.
Identify the type of DHCP server that you will use for zero touch provisioning:
- CentOS DHCP Server—If your DHCP server uses the
following command to restart the server, then select CentOS as the DHCP server type:
service dhcpd restart
- Ubuntu DHCP Server—If your DHCP server uses the
following command to restart the server, then select Ubuntu as the DHCP server type:
service isc-dhcp-server restart
- Other—If your server is not an ISC DHCP server running on Linux operating system, then you must select Other and configure the DHCP server manually.
To configure ZTP:
- While in the Deploy mode, select Zero Touch Provisioning > Setup in the Tasks pane. The Zero Touch Provisioning wizard appears.
- Specify the server details in the Server Setup wizard page as described in Specifying the Server Details.
- Click Next and proceed to specify the software image, configuration file, and the IP address range to be configured on the DHCP server. For more details, see Specifying the Software Image and Configuration Details.
- Click Next to review the details of the ZTP
profile that you created.
In the Review page, you make changes to or save a ZTP profile:
- To make changes to the profile, click the Edit button associated with the configuration you want to change.
Alternatively, you can click the appropriate buttons in the ZTP workflow at the top of the page that correspond to the configuration you want to change.
When you are finished with your modifications, click Review to return to the Review page.
- To save the ZTP profile or to save modifications to the settings of an existing profile, click Finish.
- To make changes to the profile, click the Edit button associated with the configuration you want to change.
You can use the Monitor ZTP Profiles page to view details about the switches that were provisioned using a given ZTP profile and added successfully to the Network Director inventory.
To monitor a ZTP profile:
- While in the Deploy mode, select Zero Touch Provisioning > Monitor in the Tasks pane. The Monitor ZTP Profiles page appears.
- In the Choose ZTP Profile box, select the ZTP profile
that you want to monitor.
Network Director displays the ZTP summary and details of switches that were discovered using the selected profile.
