Release Update: Network Director 3.1 Brings More Junos Fusion Fun!
Jul 31, 2017

Networks used to be relatively straightforward to manage, but the rise of cloud technologies and demand in business agility has drastically changed management requirements. Network Director (ND) is a single-pane-of-glass management platform optimized for the cloud era that allows users to visualize, analyze, and control an entire enterprise network. Since the inception of ND, the goal has always been to bring ease, control, and simplicity back into enterprise networks. As a key management and orchestration component of the Juniper Unite Cloud-Enabled Enterprise framework, ND delivers greater business agility, builds greater trust within the network, and enhances operational efficiency through insights and analytics. In alignment with Junos OS 17.1 and 17.2, ND 3.1 highlights include:  

  • Support for Junos Fusion Data Center
  • New automation and management features for Junos Fusion Enterprise
  • Enhanced port profiles
  • Media Access Control (MACsec) profile support


Junos Fusion Data Center (JFD)

The expansion of Junos Fusion technology into data center environments provide users the ability to plan, deploy, operate, and monitor JFDs through a single point of management running one Junos OS. A template driven network design allows for customization without compromising the ease of scalability of green and brown field deployments. ND automates all pre and post deployment workflows, such as SNOS image push to aggregation device, standalone satellite member provisioning, and multi-home JFD pairing to name a few. What worked well in JFE can now also be applied to JFD across the entire enterprise network.


Junos Fusion Enterprise (JFE)

Junos Fusion Enterprise reduces network complexity, simplifies management, and reduces operational costs for enterprise customers by interconnecting several switches to form a port-dense device that appears to the network as a single switch.


Enhancements in ND 3.1 offer greater levels of profile customization yet allows users to maintain full network visibility and control. Users will go through the Quick Templates feature to configure parameters such as storm control or MAC limit, 802.1x, DHCP relay, PVLAN, and Jumbo frames fragmentation in JFE.


ND 3.1 not only provides standardized profile templates, but also offers the ability to design specific network configurations to meet certain business needs and demands. New templates for Interchassis Control Link (ICL) and/or Interchassis Control Protocol (ICCP) as Link Aggregation Group (LAG) interfaces ensure redundancy and load balancing between two aggregation devices. There are options for manual ICCP provisioning, or an auto-ICCP feature to automatically establish sessions that simplify multi-home configurations. Once multi-home is setup, users can edit alias names of the satellite devices for uniform management across both aggregation devices. Another new feature ND 3.1 supports is the ability to configure and edit the FPC slot ID for a satellite device for the selected cascade port.


Enhanced Port Profiles

Profiles streamline the day-to-day operations and condense the effort needed to edit individual profile configurations. Users have an increased level of insight via two new columns, “Assigned to Devices” and “Assigned to Ports” into profile search queries from ND 3.1. From the port profile landing page, users can also filter and view profiles assignments to specific ports, devices, and interfaces within the same VLAN. The ability to quickly search and filter through specific port profiles in a large network helps users to save time and reduce manual labor, thus leading to increased efficiency.


MACsec Profiles

MACsec is an 802.1AE IEEE industry-standard security technology that provides secure communication for all traffic on point-to-point Ethernet links. Starting with ND 3.1, users can create and apply MACsec profiles to aggregation devices and have it extended to satellite ports in JFE topology. From the main landing page, users can create, edit, delete, view, and assign MACSec profiles to devices. In some industries, such as government, customers may have strict requirements for MACsec capabilities to comply with encryption regulations and practices.


…And More!

Adding more to the list of updates and enhancements, ND 3.1 continues to make things easier. ND 3.1 is capable of preserving changes made to IP fabric topologies even if the user navigates away from the page. From the Device Connectivity view, ND 3.1 represents Samsung Access Points with a unique icon so users can understand the devices in their network much faster. Through prior releases of ND, users only supported the deployment and post-deployment of L3 fabrics created in ND. With ND 3.1, users are able to discover existing L3 Fabrics created outside of ND and OpenClos. Even then, ND 3.1 can play nice with the capability to discover those existing fabrics. In the case of a brownfield Layer 3 network, users simply specify the IP subnet range and ND will take care of the rest.


Network Director is the smart, comprehensive, and automated turnkey solution for enterprises to help ease the day-to-day of administrators. The new features in ND 3.1 further simplify network operations with streamlined templates and profiles so that users have time to work on more engaging and innovative projects.


Before users begin to install ND 3.1, ensure the requirements and latest patches are up to date. For more information, please refer to the Network Director datasheet or Junos Space Network Director Release Notes. Juniper also offers a Network Director QuicksStart program that provides an on-site consultant who works with clients to plan the deployment of Junos Space and Network Director.
