The QFX5130-32CD switch provides enhanced scale with up to 1.24 million routes, 80,000 firewall filters, and 160,000 media access control (MAC) addresses. It supports high numbers of egress IPv4/IPv6 rules by programming matches in egress ternary content addressable memory (TCAM) along with ingress TCAM.

Today’s cloud-native applications have critical dependency on buffer size to prevent congestion and packet drops. The QFX5130-32CD has a 132 MB shared packet buffer that is allocated dynamically to congested ports.

With its low-power 7 nm process, the QFX5130-32CD typically consumes 373 W, bringing improvements in speed, less power consumption, and higher density on chip.

The QFX5130-48C supports 100GbE ports with SFP-DD form-factor, which helps to increase the number of ports that can be supported in a standard 1U box. This increase in port density is achieved with reduced power consumption and makes it an excellent choice for a top-of-rack device.

Having the right amount of on buffer is critical to preventing congestion and packet drops. The QFX5130-48C has an 82 MB shared packet buffer that is allocated dynamically to congested ports.

The QFX5130-48C typically consumes 285 W, bringing improvements in total power consumption and better power efficiency per port.

• Automation and programmability: The QFX5130 line supports multiple network automation features for plug-and-play operations, including zero-touch provisioning (ZTP), Network Configuration Protocol (NETCONF), Juniper Extension Toolkit (JET), Junos telemetry interface, operations and event scripts, automation rollback, and Python scripting.
  
  The QFX5130 line revolutionizes performance for data center networks by providing a programmable software-defined pipeline. The QFX5130 uses a compiler-driven switch data plane with full software program control to enable and serve a diverse set of use cases, including in-band telemetry, fine-grained filtering for traffic steering, traffic monitoring, and support for new protocol encapsulations.
• Cloud-level scale and performance: The QFX5130-32CD supports best-in-class cloud-scale L2/L3 deployments with a low latency of 630 ns and superior scale and performance. This includes L2 support for 160,000 MAC addresses and Address Resolution Protocol (ARP) learning, which scales up to 64,000 entries at 500 frames per second. It also includes L3 support for 1.24 million longest prefix match (LPM) routes and 160,000 host routes on IPv4. Additionally, the QFX5130-32CD supports 610,000 LPM routes and 80,000 host routes on IPv6, 128-way equal-cost multipath (ECMP) routes, and a filter that supports 80,000 ingress and 18,000 egress exact match filtering rules. The QFX5130-32CD supports up to 128 link aggregation groups, 4096 VLANs, and jumbo frames of 9216 bytes. Junos OS Evolved provides configurable options through a CLI, enabling each QFX5130-32CD to be optimized for different deployment scenarios.
• VXLAN overlays: The QFX5130 is capable of both L2 and L3 gateway services. Enterprises, cloud operators, and service providers can deploy overlay networks to provide L2 adjacencies for applications over L3 fabrics. The overlay networks use VXLAN in the data plane and EVPN for programming the overlays, which can operate without a controller or be orchestrated with an SDN controller.
• IEEE 1588 PTP Boundary Clock with Hardware Timestamping: IEEE 1588 PTP transparent/boundary clock is supported on QFX5130-32CD, enabling accurate and precise sub-microsecond timing information in today’s data center networks. In addition, the QFX5130-32CD supports hardware timestamping; timestamps in Precision Time Protocol (PTP) packets are captured and inserted by an onboard field-programmable gate array (FPGA) on the switch at the physical (PHY) level.
• RoCEv2: As a switch capable of transporting data as well as storage traffic over Ethernet, the QFX5130 line provides an IEEE data center bridging (DCB) converged network between servers with disaggregated flash storage arrays or an NVMe- enabled SAN. The QFX5130 line offers a full-featured DCB implementation that provides strong monitoring capabilities on the top-of-rack switch for SAN and LAN administration teams to maintain clear separation of management.
• Junos OS Evolved features: The QFX5130 line supports features such as L2/L3 unicast, EVPN-VXLAN, BGP add-path, RoCEv2 and congestion management, multicast, 128-way ECMP, dynamic load balancing capabilities, enhanced firewall capabilities, and monitoring.
• Junos OS Evolved Architecture: Junos OS Evolved is a native Linux operating system that incorporates a modular design of independent functional components and enables individual components to be upgraded independently while the system remains operational. Component failures are localized to the specific component involved and can be corrected by upgrading and restarting that specific component without bringing down the entire device. The switch’s control and data plane processes can run in parallel, maximizing CPU utilization, providing support for containerization, and enabling application deployment using LXC or Docker.
• Retained state: State is the retained information or status pertaining to physical and logical entities. It includes both operational and configuration state, comprising committed configuration, interface state, routes, hardware state, and what is held in a central database called the distributed data store (DDS). State information remains persistent, is shared across the system, and is supplied during restarts.
• Feature support: All key networking functions such as routing, bridging, management software, and management plane interfaces, as well as APIs such as CLI, NETCONF, JET, Junos telemetry interface, and the underlying data models, resemble those supported by the Junos operating system. This ensures compatibility and eases the transition to Junos Evolved.
• Automation and Monitoring: Apstra intent-based networking delivers full Day 0 through Day 2+ capabilities for IP/EVPN fabrics with closed-loop assurance in the data center for the QFX5130 line of switches. Apstra is the state-of-the art fabric management solution that empowers organizations to automate and manage their networks across virtually any data center design, vendor, and topology, making private data center as easy as cloud. Apstra provides full Day 2+ operations assurance with multiple built-in intent-based analytics probes to assure your network is running as designed, plus Apstra provides a simple UI workflow to create custom intent-based analytics to capture, enrich, and visualize data from the managed devices.

  Additionally, the Junos Evolved operating system supports a robust API set to support automation through Terraform, Ansible, ZTP, operations and event scripts, automatic rollback, and Python scripts. The QFX5130 supports Junos telemetry interface, a modern telemetry streaming tool that provides performance monitoring in complex, dynamic data centers.

Streaming data to a performance management system lets network administrators measure trends in link and node utilization and troubleshoot issues such as network congestion in real time.

Junos Telemetry Interface provides:

• Application visibility and performance management by provisioning sensors to collect and stream data and analyze the application and workload flow path through the network
• Capacity planning and optimization by proactively detecting hotspots and monitoring latency and microbursts
• Troubleshooting and root cause analysis via high-frequency monitoring and correlating overlay and underlay networks

The QFX5130 line can be deployed as a universal device in cloud data center to support 100GbE and 200GbE (with QFX5130-32CD) server access and 400GbE spine-and-leaf configurations. This optimizes data center operations by using a single device across multiple network layers. The QFX5130 line can also be deployed in more advanced overlay architectures like an EVPN-VXLAN fabric. Depending on where tunnel terminations are desired, the QFX5130 line can be deployed in either Edge Routed Bridging (ERB) deign or the Bridged Overlay architecture. Juniper offers complete flexibility and a range of data center fabric designs that cater to data centers of different sizes and scalability in cloud operator, service provider, and enterprise environments.

• Architecture 1: Edge Routed Bridging (ERB) EVPN-VXLAN with distributed anycast IP gateway architecture supporting L2 and L3 for enterprises and 5G Telco-Cloud. This type of design offers a combination of L2 stretch between multiple leaf/top-of-rack switches and L2 active/active multihoming to the server with MAC-VRF EVI L2 virtualization support as well as L3 IP VRF virtualization at the leaf/top of rack through the Type-5 EVPN-VXLAN. This type of design in data centers can be used for optimized and redundant connections toservers/compute nodes, Blade Center, IP storage nodes running ROCEv2, as well as other appliances.
• Architecture 2: Bridged Overlay (BO) EVPN-VXLAN design using MAC-VRF instances and different EVPN service-types (vLAN-aware, vLAN-bundle, vLAN-based). In this case an external to the fabric first hop IP gateway can be used, such as at the firewall or external, existing, data center gateway routers. In this design the data center fabric is offering L2 active/active multihoming using ESI-LAG and fabric wide L2 stretch between the leaf top-of-rack nodes.
• Architecture 3: Seamless DCI for ERB fabric design DCI border-leaf design with seamless T2/T2 EVPN-VXLAN to EVPN-VXLAN tunnel stitching (RFC 9014) and T5/T5 EVPN-VXLAN tunnel stitching support. With this design the data center gets the benefit of geographical redundancy for the application deployed in the private cloud data center. The QFX5130 line is used in this design also as a border-leaf node.
• Architecture 4: Collapsed spine design with ESI-LAG support and anycast IP In this case a pair of QFX5130-32CD or QFX5130-48C switches is deployed with a back-to-back connect, without a spine layer. The L2 active/active multihoming using ESI-LAG is used for the server NIC high availability as well as anycast IP gateway.

The QFX5130 line can be deployed in campus core, distribution and access layer networks using 100GbE/400GbE ports to support technologies such as EVPN multihoming and campus fabrics. Juniper offers complete flexibility in choosing any of the following validated EVPN-VXLAN designs that cater to networks of different sizes, scale, and segmentation requirements:

• EVPN multihoming (collapsed core or distribution): A collapsed core architecture combines the core and distribution layers into a single switch, turning the traditional three-tier hierarchal network into a two-tier network. EVPN Multihoming on a collapsed core eliminates the need for Spanning Tree Protocol (STP) across campus networks by providing link aggregation capabilities from the access layer to the core layer. This architecture is best suited for small to medium distributed enterprise networks and allows for consistent VLANs across the network. It uses ESI (Ethernet Segment Identifier) LAG (Link Aggregation) and is a standards-based protocol.
  • Campus Fabric Core distribution: When EVPN-VXLAN is configured across core and distribution layers, it becomes a campus Fabric Core Distribution architecture, which can be configured in two modes: centrally or edge routed bridging overlay. This architecture provides an opportunity for an administrator to move toward campus-fabric IP Clos without a fork-lift upgrade of all access switches in the existing network, while bringing in the advantages of moving to a campus fabric and providing an easy way to scale out the network.
  • Campus Fabric IP Clos: When EVPN-VXLAN is configured on all layers including access, it is called the campus fabric IP Clos architecture. This model is also referred to as “end-to-end,” given that VXLAN tunnels are terminated at the access layer. The availability of VXLAN at access provides policy enforcement and micro segmentation to the access layer (closest to the source) using standards-based Group Based Policy (GBP) to segment traffic even within a VLAN. GBP tags are assigned dynamically to clients as part of Radius transaction by Juniper Mist Cloud NAC. This topology works for small, medium, and large campus architectures that need macro and micro segmentation.

In all these EVPN-VXLAN deployment modes, the QFX5130 line can be used in the distribution or core. All three topologies are standards-based and interoperable with third-party vendors.
