    Data Center Server Access

    The QFX5110 switches are ideal for top-of-rack deployments of various densities and speeds. The QFX5110-48S offers 48 ports of native 10GbE for server connectivity, plus up to four 40GbE or 100GbE ports for uplink connectivity, providing very low oversubscription of 1.2:1 from access to aggregation. Meanwhile, the QFX5110-32Q offers 20 QSFP+ 40GbE ports for server connectivity and up to four 100GbE ports for uplink connectivity, providing an oversubscription of 2:1 from access to aggregation. Each 40GbE port can be further broken out into four 10GbE ports, providing additional options for server connectivity. The QFX5110 switches can operate in both cut-through and store-and-forward modes, delivering sustained wire-speed switching with sub-microsecond latency and low jitter for any packet size (including jumbo frames) in both modes. All QFX Series switches support extensive Layer 2 features, enabling the device to support high-density 10GbE Layer 2 access deployments. With features such as multichassis link aggregation group (MC-LAG), the QFX5110 supports active/active server dual homing and can utilize full bisectional bandwidth from server to switch. When the QFX5110 is deployed in the access layer, MC-LAG on QFX10000 switches in the aggregation layer provides maximum resiliency and full Layer 2 multipathing in the network. The Junos OS features the most advanced and robust routing capabilities in the industry. All QFX5110 switches include support for RIP and OSPF for both IPv4 and IPv6 in the base software. Advanced routing capabilities such as IS-IS and BGP are also supported. With additional capabilities like 64-way equal-cost multipath (ECMP) and BGP add path, the QFX5110 is an ideal building block for deploying the most robust Layer 3 underlay for SDN.

    Campus Deployments

    Juniper Networks campus fabrics provide a single, standards-based Ethernet VPN-Virtual Extensible LAN (EVPN-VXLAN) solution that can be deployed in any campus, whether a two-tier network with a collapsed core distribution or a campus-wide system that involves multiple buildings with separate distribution and core layers. The QFX5110-48S switch is ideal as campus distribution switches with 10GbE downlinks and 40GbE/100GbE uplinks supporting technologies like MC-LAG and EVPN multihoming. The QFX5110-32Q switch is ideal as a campus core switch with 32 ports of 40GbE and support for campus fabric with EVPN-VXLAN. Juniper campus fabrics support these validated architectures:
    • MC-LAG and EVPN Multihoming (Collapsed Core/Distribution). A pair of interconnected QFX5110 switches can be deployed to provide EVPN multihoming (ESI-LAG) or multichassis link aggregation (MC-LAG) in a collapsed core/distribution configuration. This eliminates the need for Spanning Tree Protocol (STP) across the campus network by providing multihoming capabilities from the access to the distribution layer, while distribution to the core is an L3 IP fabric. ESI-LAG also supports horizontal scaling with more than two devices in the distribution layer and can extend EVPN to the core.
    Figure 2: QFX5110 switch as a campus collapsed core/distribution switch with EVPN multihoming (ESI-LAG) and MC-LAG support
    • Campus Fabric Core-Distribution. A pair of interconnected QFX5110 switches can provide EVPN L2 and L3 VXLAN gateway support. This eliminates the need for STP across the campus network by providing a multihoming capability from the access to the distribution layer, while distribution to the core is an L3 IP fabric using EVPN technology. The IP fabric can also extend to connect multiple enterprise buildings, while VXLAN allows stretching L2 across buildings. An IP Clos network between the distribution and the core layers can exist in two modes, both of which are supported by the QFX5110 switch:
      • Centrally routed bridging overlay: An IRB interface placed at a central location in the fabric (in this case, a core device)
      • Edge routed bridging overlay: An IRB interface placed at the edge of the fabric (in this case, a distribution device)
    • Campus Fabric IP Clos: The campus fabric IP Clos architecture pushes VXLAN Layer 2/3 gateway functionality to the access layer. In this architecture, the QFX5110 switch acts as an IP fabric distribution switch.

    Features and Benefits

    • Automation—The QFX5110 switches support a number of features for network automation and plug-and-play operations. Features include zero touch provisioning, operations and event scripts, automatic rollback, and Python scripting. The switch also supports integration with VMware NSX Layer 2 Gateway Services, and OpenStack.
    • Flexible Forwarding Table—The QFX5110 includes a Unified Forwarding Table (UFT), which allows the hardware table to be carved into configurable partitions of Layer 2 media access control (MAC), Layer 3 host, and longest prefix match (LPM) tables. In a pure L2 environment, the QFX5110 supports 288,000 MAC addresses. In Layer 3 mode, the table can support 208,000 host entries. In LPM mode, it can support 128,000 prefixes. Junos OS provides configurable options through a CLI so that each QFX5110 can be optimized for different deployment scenarios.
    • Intelligent Buffer Management—The QFX5110 switches have a total of 16 MB shared buffers. While 25% of the total buffer space is dedicated, the rest is shared among all ports and is user configurable. The intelligent buffer mechanism in the QFX5110 effectively absorbs traffic bursts while providing deterministic performance, significantly increasing performance over static allocation.
    • MPLS—QFX5110 switches support a broad set of MPLS features, including L3 VPN, IPv6 provider edge router (6PE), RSVP traffic engineering, and LDP to allow standards-based network segmentation and virtualization. This enables the QFX5110 to be deployed as a low-latency MPLS label-switching router (LSR).
    • VXLAN Overlays—The QFX5110 switch is capable of supporting Layer 2 and Layer 3 gateway services. Customers can deploy overlay networks to provide Layer 2 adjacencies for applications over Layer 3 fabrics. The overlay networks utilize VXLAN in the data plane and EVPN or OVSDB to program the overlays. The overlays can operate without a controller, or they can be orchestrated with an SDN controller.

    Data Center Server Access

    The QFX5120-48Y and QFX5120-48YM support tri-speed 1GbE/10GbE/25GbE, making them a perfect fit for top-of-rack deployments. The 48 ports of native 10GbE/25GbE for server connectivity, plus up to eight 40GbE or 100GbE ports for uplink connectivity, provide very low oversubscription of 1.5:1 from access to aggregation. The QFX5120-48T supports dual-speed 1GbE/10GbE, also making it a perfect fit for top-of-rack deployments. The 48 native 10GbE RJ-45 copper ports for server connectivity, plus up to six 40GbE or 100GbE ports for uplink connectivity, provide an unsubscribed (0.8:1) access-to-aggregation ratio. The QFX5120-32C can also be used for high-density 25GbE server connectivity, with an option to break out the 100GbE ports into four 25GbE ports.
    In Figure 1, the QFX5120 is deployed as a leaf acting as an edge-routed gateway. In this topology, the VXLAN tunnel encapsulation and decapsulation take place on the QFX5120 leaf switches, while Juniper Networks QFX5200-32C or Juniper Networks QFX5210-64C spine switches are used for IP transit. Juniper Networks QFX5110-32Q switches can also be used in the spine to build a 40GbE fabric.

    Figure 1: Edge-routed bridging at the leaf with QFX5200-32C/QFX5210-64C as spine switches
    In Figure 2, the QFX5120-48YM leaf and Juniper Networks QFX10008 Switch spine are deployed as EVPN-VXLAN switches acting as centrally routed gateways or distributed edge-routed gateways. If centrally routed bridging is used, the VXLAN tunnel encapsulation and decapsulation occur on the spine switches for inter-IRB (integrated routing and bridging) symmetric routing purposes. If edge-routed bridging is used, the IP first hop gateways are distributed at the leaf-level QFX5120-48YM switches using Type 5 symmetric inter-IRB routing. When using a QFX10000-30C-M MACsec line card installed in a spine QFX10008 Switch working with a leaf QFX5120-48YM switch, the leaf-to-spine architecture offers end-to-end MACsec AES-256 capabilities.

    Data Center Spine

    The QFX5120-32C, with 32 ports of 100GbE, can serve as the spine in small to medium-sized enterprise data centers. The QFX5120-32C can be deployed in a three-stage IP Clos with EVPN-VXLAN overlay to support as many as 1500 server access ports. The QFX5120-48Y/QFX5120-48YM and QFX5120-32C can also be used as a collapsed spine data center deployment, offering Ethernet segment identifier-link aggregation group (ESI-LAG) connectivity to the rest of the network infrastructure blocks. All QFX5120 switches can operate in both cut-through and store-and-forward modes, delivering sustained wire-speed switching with sub-microsecond latency and low jitter for any packet size (including jumbo frames) in either mode. With features such as multichassis link aggregation (MC-LAG), the QFX5120 supports active/active server dual-homing and can use full bisectional bandwidth from server to switch. Equipped with Junos OS, the QFX5120 supports the most advanced and robust routing capabilities in the industry, OSPF for both IPv4 and IPv6, as well as advanced routing capabilities such as IS-IS and BGP. With additional capabilities such as 64-way equal-cost multipath (ECMP) and BGP add path, the QFX5120 is an ideal building block for deploying the most robust L3 underlay for SDN.  

    Campus Deployments

    Juniper campus fabrics provide a single, standards-based Ethernet VPN-Virtual Extensible LAN (EVPN-VXLAN) solution that can be deployed in any campus, whether a two-tier network with a collapsed core distribution or a campus-wide system that involves multiple buildings with separate distribution and core layers. The QFX5120-48Y and QFX5120-48YM are ideal as campus distribution switches with 10GbE/25GbE downlinks and 40GbE/100GbE uplinks supporting technologies like MC-LAG and EVPN multihoming. The QFX5120-32C is ideal as a campus core switch with 32 ports of 100GbE and support for technologies like campus fabric core-distribution. The QFX5120-48T supports dual-speed 1GbE/10GbE, also making it a perfect fit for top-of-rack deployments in campus environments for server connectivity. Juniper campus fabrics support the following validated architectures:
    • MC-LAG and EVPN Multihoming (Collapsed Core/Distribution): A pair of interconnected QFX5120 switches can be deployed to provide EVPN multihoming (ESI-LAG) or multichassis link aggregation (MC-LAG) in a collapsed core/distribution configuration. This eliminates the need for Spanning Tree Protocol (STP) across the campus network by providing multihoming capabilities from the access to the distribution layer, while distribution to the core is an L3 IP fabric. ESI-LAG also supports horizontal scaling with more than two devices in the distribution layer and can extend EVPN to the core.
    • Campus Fabric Core-Distribution: A pair of interconnected QFX5120 switches can provide EVPN L2 and L3 VXLAN gateway support. This eliminates the need for STP across the campus network by providing a multihoming capability from the access to the distribution layer, while distribution to the core is an L3 IP fabric using EVPN technology. The IP fabric can also extend to connect multiple enterprise buildings, while VXLAN allows stretching of L2 across buildings. An IP Clos network between the distribution and the core layers can exist in two modes, both of which are supported by the QFX5120:
      • Centrally routed bridging overlay: An IRB interface placed at a central location in the fabric (in this case, a core device)
      • Edge routed bridging overlay: An IRB interface placed at the edge of the fabric (in this case, a distribution device)
    • Campus Fabric IP Clos: The Campus Fabric IP Clos architecture pushes VXLAN Layer 2/3 gateway functionality to the access layer. In this architecture, the QFX5120 switch acts as an IP fabric distribution switch.

    Features and Benefits

    • Automation: The QFX5120 supports a number of network automation and plug-and-play operational features, including ZTP and event scripts, automatic rollback, and Python scripting.
    • Flexible forwarding table: The QFX5120 includes a unified forwarding table, which allows the hardware table to be carved into configurable partitions of L2 media access control (MAC), L3 host, and longest prefix match (LPM) tables. In a pure L2 environment, the QFX5120 supports 288,000 MAC addresses. In L3 mode, the table can support 208,000 host entries. In LPM mode, it can support 351,000 prefixes. Junos OS provides configurable options through a CLI that can optimize the QFX5120 for various deployment scenarios.
    • Intelligent buffer management: The QFX5120 features a total of 32 MB of shared buffers. While 25% of the total buffer space is dedicated, the rest is shared among all ports and is user configurable. The intelligent buffer mechanism in the QFX5120 effectively absorbs traffic bursts while providing deterministic performance, significantly increasing performance over static allocation.
    • MPLS: A broad set of MPLS features, including L3 VPN, IPv6 provider edge router (6PE), RSVP traffic engineering, and LDP, allow standards-based network segmentation and virtualization, enabling the QFX5120 to be deployed as a low latency MPLS label-switching router (LSR).
    • VXLAN overlays: The QFX5120 switch is capable of both L2 and L3 gateway services. Customers can deploy overlay networks to provide L2 adjacencies for applications over L3 fabrics. The overlay networks use VXLAN in the data plane and EVPN or Open vSwitch Database (OVSDB) for programming the overlays.
    • MACsec and hop-by-hop encryption: The QFX5120-48YM supports IEEE 802.1AE MACsec AES-256, providing link-layer data confidentiality, data integrity, and data origin authentication. The MACsec feature enables the QFX5120-48YM to support 2 Tbps of near line-rate hardware-based traffic encryption on all 100GbE, 40GbE, 25GbE, 10GbE, and 1GbE ports. Defined by IEEE 802.1AE, MACsec provides secure, encrypted communication at the link layer that is capable of identifying and preventing threats from denial-of-service (DoS) and intrusion attacks, as well as man-in-the-middle, masquerading, passive wiretapping, and playback attacks launched from behind the firewall. When MACsec is deployed on switch ports, all traffic is encrypted on the wire, but traffic inside the switch is not. This allows the switch to apply network capabilities such as quality of service (QoS) and sFlow to each packet without compromising the security of packets on the wire.
    In addition, Ethernet-based WAN networks can use MACsec to provide link security over long haul connections. MACsec is transparent to Layer 3 and higher layer protocols and is not limited to IP traffic; it works with any type of wired or wireless traffic carried over Ethernet links.
    • Virtual chassis: The QFX5120 supports Juniper Networks’ unique virtual chassis technology, which enables up to two interconnected switches to operate as a single, logical device with a single IP address. This technology allows campus enterprises to eliminate STP and efficiently utilize network links. QFX5120-48Y (starting with Junos 19.3), QFX5120-32C (staring with Junos 20.3) and QFX5120-48T (starting with Junos 20.2) support virtual chassis. Note: QFX5120-48YM does not support virtual chassis at this time; this feature is reserved for a future release.

Native 400GbE Configuration The QFX5130-32CD offers 32 ports in a 1 U form factor. The high-speed ports support a wide variety of configurations, including 100GbE and 40GbE. High-Density Configurations The QFX5130 is optimized for high-density fabric deployments, providing options for 32 ports of 400GbE, 100GbE, or 40GbE. Flexible Connectivity Options The QFX5130 offers a choice of interface speeds for server and intra-fabric connectivity, providing deployment versatility and investment protection.   Key Product Differentiators: Increased Scale and Buffer The QFX5130 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. 132MB Shared Packet Buffer Today’s cloud-native applications have critical dependency on buffer size to prevent congestion and packet drops. The QFX5130 has 132 MB shared packet buffer that is allocated dynamically to congested ports. Programmability The QFX5130 revolutionizes performance for data center networks by providing a programmable software-defined pipeline in addition to the comprehensive feature set provided in the Juniper Networks QFX5120 Switch line. 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. Power Efficiency With its low-power 7 nm process, the QFX5130 consumes a maximum of 973 W, bringing improvements in speed, less power consumption, and higher density on chip. Management, Monitoring, and Analytics Data Center Fabric Management Juniper® Apstra provides operators with the power of intentbased network design to help ensure changes required to enable data center services can be delivered rapidly, accurately, and consistently. Operators can further benefit from the built-in assurance and analytics capabilities to resolve Day 2 operations issues quickly. Apstra key features are: • Automated deployment and zero-touch deployment • Continuous fabric validation • Fabric life-cycle management • Troubleshooting using advanced telemetry   Features and Benefits: • Automation and programmability: The QFX5130-32CD supports a number of 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. • Cloud-level scale and performance: The QFX5130 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 supports 610,000 LPM routes and 80,000 host routes on IPv6, 128-way equalcost multipath (ECMP) routes, and a filter that supports 80,000 ingress and 18,000 egress exact match filtering rules. The QFX5130 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 to be optimized for different deployment scenarios. • VXLAN overlays*: The QFX5130 is capable of both L2 and L3 gateway services. Customers can deploy overlay networks to provide L2 adjacencies for applications over L3 fabrics. The overlay networks use VXLAN in the data plane and EVPN or Open vSwitch Database (OVSDB) 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, enabling accurate and precise sub-microsecond timing information in today’s data center networks. In addition, the QFX5130 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. • Data packet timestamping*: When the optional data packet timestamping feature is enabled, select packets f lowing through the QFX5130 are timestamped with references to the recovered PTP clock. When these packets are received by nodes in the network, the t imestamping information can be mirrored onto monitoringtools to identify network bottlenecks that cause latency. This analysis can also be used for legal and compliance purposes in institutions such as financial trading, video streaming, and research establishments. •RoCEv2*: As a switch capable of transporting data as well as storage traffic over Ethernet, the QFX5130 provides an IEEE data center bridging (DCB) converged network between servers with disaggregated flash storage arrays or an NVMe-enabled storage-area network (SAN). The QFX5130 offers a full-featured DCB implementation that provides strong monitoring capabilities on the topof-rack switch for SAN and LAN administration teams to maintain clear separation of management. The RDMA over Converged Ethernet version 2 (RoCEv2) transit switch functionality, including priority-based flow control (PFC) and Data Center Bridging Capability Exchange (DCBX), are included as part of the default software. • Junos Evolved features: The QFX5130 switch supports features such as L2/L3 unicast, EVPN-VXLAN*, BGP addpath, RoCEv2 and congestion management, multicast, 128way ECMP, dynamic load balancing capabilities, enhanced f irewall 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 enablesindividual 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 having to bring down the entire device.

    Architecture and Key Components

    The QFX5200 can be used in L3 fabrics and L2 networks with MC-LAG. You can choose the architecture that best suits your deployment needs and easily adapt and evolve as requirements change over time. The QFX5200 switch serves as the universal building block for these two switching architectures, enabling data center operators to build cloud networks their way.
    • Layer 3 fabric: For customers looking to build scale-out data centers, a Layer 3 spine-and-leaf Clos fabric is ideal due to its predictable, nonblocking performance and scale characteristics. For example, a two-tier fabric built with QFX5200 switches as leafs and Juniper Networks QFX10000 switches as the spine can scale to support up to 18,432 40GbE ports, or 36,864 25GbE or 10GbE server ports in a single fabric. One of the most complicated tasks in building an IP fabric is assigning all of the implementation details, including IP addresses, BGP autonomous system (AS) numbers, routing policies, loopback address assignments, and many others. Automating the creation of an IP fabric at a large scale is equally difficult. To address these challenges, Juniper has created the OpenClos project to provide free and open-source tools that automate the creation of IP fabrics in the data center. A set of Python scripts developed as an open-source project that live on GitHub, OpenClos takes a set of inputs that describe the shape and size of a data center and outputs switch configuration files, as well as a cabling plan.
    • MC-LAG: The QFX5200 supports the MC-LAG protocol between two switches to eliminate Spanning Tree Protocol (STP) in traditional L2 networks when deployed in the aggregation layer. The active/active operation of MC-LAG ensures complete bandwidth utilization between the network’s access and aggregation layers, while the dual control plane technology ensures the highest availability for applications.

    Carrier-Class Network Operating System

    The QFX5200 runs the same Junos OS used by all other Juniper Networks QFX Series and EX Series Ethernet Switches, as well as the Juniper routers that power the world’s largest and most complex networks. By using a common operating system, Juniper delivers a consistent implementation and operation of control plane features across all products. Junos OS employs a highly available modular architecture that prevents isolated failures from bringing down an entire system. Key Junos OS features that enhance the functionality and capabilities of the QFX5200 include:
    • Software modularity, with process modules running independently in their own protected memory space and with the ability to do process restarts
    • Commit and rollback functionality, which ensures error-free network configurations
    • A powerful set of scripts for on-box problem detection, reporting, and resolution
    Figure 4: Junos OS software infrastructure

    Junos Telemetry Interface

    The QFX5200 supports Junos Telemetry Interface (JTI)*, a modern telemetry streaming tool designed for performance monitoring in complex, dynamic data centers. Streaming data to a performance management system enables network administrators to measure trends in link and node utilization, and troubleshoot such issues as network congestion in real time. JTI provides these capabilities:
    • Application visibility and performance management by provisioning sensors to collect and stream data and analyze 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

    Management, Monitoring, and Analytics

    Data Center Fabric Management: Juniper® Apstra provides operators with the power of intent-based network design to help ensure changes required to enable data center services can be delivered rapidly, accurately, and consistently. Operators can further benefit from the built-in assurance and analytics capabilities to resolve Day 2 operations issues quickly. Apstra key features are:
    • Automated deployment and zero-touch deployment
    • Continuous fabric validation

    Features and Benefits

    • Automation and Programmability: The QFX5200 supports numerous network automation features, including operations and event scripts, ZTP, and Juniper plug-ins for OpenStack Neutron.
    • Flexible Forwarding Table: The QFX5200 switch’s Flexible Forwarding Table (FFT) allows the hardware table to be carved into configurable partitions of L2 media access control (MAC), L3 host, and longest prefix match (LPM) tables. In a pure L2 environment, the QFX5200 supports 136,000 MAC addresses; in L3 mode, the table supports 104,000 host entries; while in LPM mode, it supports 128,000 prefixes. A filter-based forwarding mode supports 64,000 exact match filtering rules. Junos OS provides configurable options through a CLI, enabling each QFX5200 to be optimized for different deployment scenarios.
    • MPLS: The QFX5200 supports a broad set of MPLS features, including L3 VPN, RSVP traffic engineering, and LDP to support standards-based multitenancy and network virtualization with per-flow SLAs at scale. The QFX5200 can also be deployed as a low-latency MPLS label-switching router (LSR) or MPLS provider edge (PE) router in smaller scale environments. The QFX5200 and the Juniper Networks QFX5100 switch are the industry’s most compact, low-latency, high-density, low-power family of switches to offer an MPLS feature set.
    • FCoE: As a Fibre Channel over Ethernet (FCoE) transit switch, the QFX5200 provides an IEEE data center bridging (DCB) converged network between FCoE-enabled servers and an FCoE-to-FC gateway or FCoE-enabled Fibre Channel storage area network (SAN). The QFX5200 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. In addition, FCoE Initialization Protocol (FIP) snooping provides perimeter protection, ensuring that the presence of an Ethernet layer does not impact existing SAN security policies. FCoE LAG support transports FCoE traffic and regular Ethernet traffic across the same link aggregation bundle over ports on a converged network adapter (CNA), while guaranteeing that the same physical link is used for an FCoE point-to-point virtual connection.
    The FCoE transit switch functionality, including priority-based flow control (PFC) and Data Center Bridging Capability Exchange (DCBX), are included as part of the default software.

    QFX5200-32C-S Hardware with SONiC Support

    The QFX5200-32C-S Switch supports Juniper’s SONiC implementation, delivering best-of-breed hardware and routing for cloud providers while taking advantage of the flexibility, resiliency, and cost savings of SONiC’s open and disaggregated architecture. The SONiC-enabled QFX5200-32C-S, which plugs seamlessly into a unified SONiC network infrastructure, leverages the existing QFX5200-32C hardware and includes support for ONIE and IDEEPROM TLV formats. ONIE and SONiC images are installed on the hardware at the factory. The Juniper-provided SONiC image includes the platform and FRU device drivers only; it does not include Juniper software features such as Layer 2, Layer 3, MPLS, EVPN, and VXLAN, among others. The platform and FRU device drivers are uploaded to the SONiC Github open source repository. Customers can use their private SONiC patches by building and upgrading the ONIE and SONiC images on the switch. Juniper complements the SONiC OS with the containerized Routing Protocol Daemon (cRPD), a full-function routing and management stack packaged as a container, ensuring a common end-to-end routing experience across different tiers in the data center. In addition, the cRPD enables high-performance telemetry, automation, and programmability in a lightweight deployment.

  • QFX5210 Ethernet Switch

    ASK FOR PRICE

    Product Overview

    The QFX5210 Switch is a flexible, 64-port, fixed-configuration switch designed for spine-and-leaf applications in next-generation IP fabric networks. Featuring line-rate, high-density QSFP+/QSFP28 ports supporting 10GbE, 25GbE, 40GbE, and 100GbE connections, the QFX5210 offers an advanced Layer 2, Layer 3, and MPLS feature set. This allows network operators to build large, high-density IP fabrics that support network virtualization and intelligent traffic forwarding based on proven, Internet-scale technology, while enabling easy upgrades to 25GbE servers. Additionally, the QFX5210-64C-S platform includes support for SONiC, continuing Juniper’s commitment to disaggregation, allowing customers to innovate quickly and easily while simplifying operations.

    Product Description

    Network operators are increasingly deploying scale-out spine-and-leaf IP fabric architectures built with fixed-configuration switches to support growing east-west traffic in the data center. The Juniper Networks® QFX5210 Switch is a next-generation, fixed-configuration spine/leaf switch that offers flexible, cost-effective, high-density 10GbE, 25GbE, 40GbE, and 100GbE interfaces for IP fabric networks, providing deployment versatility, investment protection, and future-proofing for today’s data centers. The QFX5210 Switch’s high port density also contributes to simplified Clos architectures, eliminating network tiers while reducing complexity and cost. Like other Juniper Networks QFX Series Switches, the QFX5210 supports advanced L2, L3, and MPLS features. For large public cloud providers—among the first to adopt 25GbE servers to meet explosive workload growth—the QFX5210 enables very large, dense, and fast IP fabrics based on proven Internet scale technology. The QFX5210 runs the same reliable, high-performance Junos® operating system used by network operators around the world.

    QFX5210 Deployment Options

    Table 1 shows some of the many QFX5210 deployment options, including top-of-rack access as well as spine-and-leaf configurations in a centralized or distributed gateway architecture.
    Table 1. QFX5210 Deployment Options
    Port Combinations Deployment
    64x100GbE Spine/leaf
    96x25GbE + 8x100GbE 25GbE access
    The QFX5210 can be positioned as a top-of-rack device in a centralized gateway architecture (also known as centrally routed bridging, or CRB). Figure 1 shows the QFX5210 deployed as an access switch with the Juniper Networks QFX10000 line of Switches acting as the spine device configured as a central gateway. In this topology, the QFX10000 can also be configured as a collapsed spine and edge device, acting as a central gateway for Ethernet VPN (EVPN)-Virtual Extensible LAN (VXLAN), MPLS, and other tunneling protocols. The 100GbE ports on the QFX5210 can be channelized to support 4x25GbE or 4x10GbE downlinks.
    Figure 1: QFX5210 and QFX10002 in a leaf-spine deployment with centralized gateway
    The QFX5210 can also be positioned as a lean spine device in a distributed gateway architecture (also known as edge-routed bridging, or ERB). Figure 2 shows QFX5120 switches deployed as access switches configured as distributed gateways and QFX5210 switches deployed as spine switches.

    Architecture and Key Components

    The QFX5210 is a compact, 2 U platform featuring 64 quad small form-factor pluggable plus (QSFP+) transceivers or QSFP28 ports, with two redundant 1100 W AC/DC power supplies and four fan trays. A QSFP28 module can be used to provide a 1x100GbE connection or 4x25GbE connections using breakout cables. A QSFP+ module can be used to provide a 1x40GbE connection or 4x10GbE connections using breakout cables. The QFX5210 features a high-throughput 12.8 Tbps Packet Forwarding Engine (PFE). Control plane performance is further enhanced with the Intel Broadwell-DE, 4 Core, 2.2 GHz CPU, and 16 GB DDR4, 100 GB SSD storage. The QFX5210 can be used in L3 fabrics and L2 networks with multichassis link aggregation (MC-LAG). Customers can choose the architecture that best suits their deployment needs and easily adapt and evolve as requirements change over time. The QFX5210 switch serves as a universal building block for these switching architectures, enabling data center operators to build cloud networks their way.
    • IP Fabric: For customers looking to build scale-out data centers, an L3 spine-and-leaf Clos fabric is ideal due to its predictable, nonblocking performance and scale characteristics. For example, a two-tier fabric built with the QFX5210 Switch as leafs and QFX10000 Switches as the spine can scale to support up to 18,432 40GbE ports, or 36,864 25GbE or 10GbE server ports in a single fabric.
    • Overlays: Customers can deploy overlay networks to provide L2 adjacencies for applications over L3 fabrics. The overlay networks use VXLAN in the data plane and EVPN to program the overlays. The overlays can operate without a controller or can be orchestrated with a fabric management orchestrator to provide L2/L3 overlay virtual networking and security for bare-metal servers and virtual workloads. QFX5210 switches can also integrate with VMware NSX.
    • MC-LAG: The QFX5210 supports the MC-LAG protocol between two switches, eliminating Spanning Tree Protocol (STP) in traditional L2 networks when deployed in the aggregation layer. MC-LAG’s active/active operation ensures complete bandwidth utilization between the network’s access and aggregation layers, while the dual control plane technology ensures the highest availability for applications.

    Features and Benefits

    • Flexible connectivity options: The QFX5210 offers a choice of 10GbE, 25GbE, 40GbE, and 100GbE interface speeds for server and intra-fabric connectivity, providing deployment versatility and investment protection.
    • Automation and programmability: The QFX5210 supports numerous network automation features, including operations and event scripts, ZTP, and Juniper plug-ins for OpenStack Neutron.
    • Flexible Forwarding Table: The QFX5210 switch’s Flexible Forwarding Table (FFT) allows the hardware table to be carved into configurable partitions of L2 media access control (MAC), L3 host, and longest prefix match (LPM) tables. Junos OS provides configurable options through a CLI, enabling each QFX5210 to be optimized for different deployment scenarios.
    • MPLS: The QFX5210 supports a broad set of MPLS features, including L3 VPN, RSVP traffic engineering, and LDP to support standards-based multitenancy and network virtualization with per-flow SLAs at scale. The QFX5210 can also be deployed as a low-latency MPLS label-switching router (LSR) or MPLS provider edge (PE) router in smaller scale environments. The QFX5210, along with the Juniper Networks QFX5220, QFX5200, QFX5120, QFX5110, and QFX5100 switches, is among the industry’s most compact, low-latency, high-density, low-power family of switches to offer an MPLS feature set.
    • RoCEv2: As a switch capable of transporting data as well as storage traffic over Ethernet, the QFX5210 provides an IEEE data center bridging (DCB) converged network between servers with disaggregated flash storage arrays or an NVMe-enabled storage area network (SAN). The QFX5210 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. The RDMA over Converged Ethernet version 2 (RoCEv2) transit switch functionality, including DiffServ code point (DSCP) priority-based flow control (PFC) and Data Center Bridging Capability Exchange (DCBX) with Explicit Congestion Notification (ECN) are included as part of the default software.

    QFX5210-64C-S Hardware with SONiC Support

    The QFX5210-64C-S Switch supports Juniper’s SONiC implementation, delivering best-of-breed hardware and routing for cloud providers while taking advantage of the flexibility, resiliency, and cost savings of SONiC’s open and disaggregated architecture. The SONiC-enabled QFX5210-64C-S, which plugs seamlessly into a unified SONiC network infrastructure, leverages the existing QFX5210-64C hardware and includes support for ONIE and IDEEPROM TLV formats. ONIE and SONiC images are installed on the hardware at the factory. The Juniper-provided SONiC image includes the platform and FRU device drivers only; it does not include Juniper software features such as L2, L3, MPLS, EVPN, VXLAN, etc. The platform and FRU device drivers are uploaded to the SONiC Github open-source repository. Customers can use their private SONiC patches by building and upgrading the ONIE and SONiC images on the switch. Juniper complements the SONiC OS with the containerized routing protocol process (cRPD), a full-function routing and management stack packaged as a container, ensuring a common end-to-end routing experience across different tiers in the data center. In addition, cRPD enables high-performance telemetry, automation, and programmability in a lightweight deployment.

    Architecture and Key Components

    The QFX5220 can be used in L3 fabrics and L2 networks. You can choose the architecture that best suits your deployment needs and easily adapt and evolve as requirements change over time. The QFX5220 serves as the universal building block for these two switching architectures, enabling data center operators to build cloud networks in their own way.
    • Layer 3 fabric: For customers looking to build scale-out data centers, a Layer 3 spine-and-leaf Clos fabric provides predictable, nonblocking performance and scale characteristics. A two-tier fabric built with QFX5220 switches as leaf devices and Juniper Networks QFX10000 line of Switches as the spine can scale to support up to 128 40GbE ports or 128 25GbE and/or 10GbE server ports in a single fabric. One of the most complicated tasks when building an IP fabric is assigning all the implementation details, including IP addresses, BGP autonomous system numbers, routing policies, loopback address assignments, and others. Automating the creation of an IP fabric at a large scale is equally difficult. To address these challenges, Juniper has created the OpenClos project to provide free, open-source tools that automate the creation of IP fabrics in the data center. A set of Python scripts developed as an open-source project on GitHub, OpenClos takes a set of inputs that describe the shape and size of a data center and produces switch configuration files and a cabling plan
    Junos Evolved ensures a high feature and bug fix velocity and provides first-class access to system state, allowing customers to run DevOps tools, containerized applications, management agents, specialized telemetry agents, and more.

    Features and Benefits

    • Automation and programmability: The QFX5220 supports numerous network automation features, including operations and event scripts and ZTP.
    • Cloud-level scale and performance: The QFX5220 supports best-in-class cloud-scale L2/L3 deployments with a low latency of 750 ns and a superior scale and performance. This includes L2 support for 8192 media access control (MAC) addresses and Address Resolution Protocol (ARP) learning, which scales up to 32,000 entries at 500 frames per second. It also includes L3 support for 336,000 longest prefix match (LPM) routes and 380,000 host routes on IPv4. Additionally, the QFX5220 supports 130,000 LPM routes and 130,000 host routes on IPv6, 128-way equal-cost multipath (ECMP) routes, and a filter that supports 768 (ingress) and 2558† (egress) exact match filtering rules. The QFX5220 supports up to 128 link aggregation groups, 4096 VLANs, and Jumbo frames of 9216 bytes. Junos Evolved provides configurable options through a CLI, enabling each QFX5220 to be optimized for different deployment scenarios.
    † Ingress/egress scale numbers may be lower when used concurrently.
    • MPLS: The QFX5220 supports a broad set of MPLS features, including L3 VPN, RSVP traffic engineering, and LDP to support standards-based multitenancy and network virtualization with per-flow service-level agreements (SLAs) at scale. The QFX5220 can also be deployed as a low-latency MPLS label-switching router (LSR) or MPLS provider edge (PE) router in smaller scale environments. The QFX5220, along with Juniper Networks QFX5100 and QFX5200 switches, are the most compact, low-latency, high-density, low-power family of switches to offer an MPLS feature set in the industry.
    • IEEE 1588 PTP Boundary Clock with Hardware Timestamping*: IEEE 1588 PTP Transparent/Boundary Clock is supported on QFX5220, enabling accurate and precise sub-microsecond timing information in today’s data center networks. In addition, the QFX5220 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.
    • Data packet timestamping*: When the optional data packet timestamping feature is enabled, selected packets flowing through QFX5220 switches are timestamped with references to the recovered PTP clock. When these packets are received by nodes in the network, the packet timestamping information can be mirrored onto monitoring tools for detailed analysis, helping identify bottlenecks in the network that cause latency. This information also helps with network performance analysis and record keeping for legal and compliance purposes, which is required by certain business transactions such as financial trading, video streaming, and research establishments.
    • RoCEv2: As a switch capable of transporting data as well as storage traffic over Ethernet, the QFX5220 provides an IEEE data center bridging (DCB) converged network between servers with disaggregated flash storage arrays or an NVMe-enabled storage area network (SAN). The QFX5220 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. The RDMA over Converged Ethernet version 2 (RoCEv2) transit switch functionality, including priority-based flow control (PFC) and Data Center Bridging Capability Exchange (DCBX), are included as part of the default software.
    • Junos OS Evolved: Junos 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 having to bring down the entire device.
    • 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, Juniper Extension Toolkit (JET), Junos Telemetry Interface (JTI), and the underlying data models, resemble those supported by Junos. This ensures compatibility and eases the transition to Junos Evolved.

    Junos Telemetry Interface

    The QFX5220 supports Junos Telemetry Interface (JTI), 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. JTI 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.

    Figure 2: 100GbE fabric in a typical cloud data center
    Figure 3: Private cloud data center with the QFX5220-128C as lean spine

    Architecture and Key Components

    The QFX5220 can be used in L3 fabrics and L2 networks. You can choose the architecture that best suits your deployment needs and easily adapt and evolve as requirements change over time. The QFX5220 serves as the universal building block for these two switching architectures, enabling data center operators to build cloud networks in their own way.
    • Layer 3 fabric: For customers looking to build scale-out data centers, a Layer 3 spine-and-leaf Clos fabric provides predictable, nonblocking performance and scale characteristics. A two-tier fabric built with QFX5220 switches as leaf devices and Juniper Networks QFX10000 line of Switches as the spine can scale to support up to 128 40GbE ports or 128 25GbE and/or 10GbE server ports in a single fabric. One of the most complicated tasks when building an IP fabric is assigning all the implementation details, including IP addresses, BGP autonomous system numbers, routing policies, loopback address assignments, and others. Automating the creation of an IP fabric at a large scale is equally difficult. To address these challenges, Juniper has created the OpenClos project to provide free, open-source tools that automate the creation of IP fabrics in the data center. A set of Python scripts developed as an open-source project on GitHub, OpenClos takes a set of inputs that describe the shape and size of a data center and produces switch configuration files and a cabling plan
    Junos Evolved ensures a high feature and bug fix velocity and provides first-class access to system state, allowing customers to run DevOps tools, containerized applications, management agents, specialized telemetry agents, and more.

    Features and Benefits

    • Automation and programmability: The QFX5220 supports numerous network automation features, including operations and event scripts and ZTP.
    • Cloud-level scale and performance: The QFX5220 supports best-in-class cloud-scale L2/L3 deployments with a low latency of 750 ns and a superior scale and performance. This includes L2 support for 8192 media access control (MAC) addresses and Address Resolution Protocol (ARP) learning, which scales up to 32,000 entries at 500 frames per second. It also includes L3 support for 336,000 longest prefix match (LPM) routes and 380,000 host routes on IPv4. Additionally, the QFX5220 supports 130,000 LPM routes and 130,000 host routes on IPv6, 128-way equal-cost multipath (ECMP) routes, and a filter that supports 768 (ingress) and 2558† (egress) exact match filtering rules. The QFX5220 supports up to 128 link aggregation groups, 4096 VLANs, and Jumbo frames of 9216 bytes. Junos Evolved provides configurable options through a CLI, enabling each QFX5220 to be optimized for different deployment scenarios.
    † Ingress/egress scale numbers may be lower when used concurrently.
    • MPLS: The QFX5220 supports a broad set of MPLS features, including L3 VPN, RSVP traffic engineering, and LDP to support standards-based multitenancy and network virtualization with per-flow service-level agreements (SLAs) at scale. The QFX5220 can also be deployed as a low-latency MPLS label-switching router (LSR) or MPLS provider edge (PE) router in smaller scale environments. The QFX5220, along with Juniper Networks QFX5100 and QFX5200 switches, are the most compact, low-latency, high-density, low-power family of switches to offer an MPLS feature set in the industry.
    • IEEE 1588 PTP Boundary Clock with Hardware Timestamping*: IEEE 1588 PTP Transparent/Boundary Clock is supported on QFX5220, enabling accurate and precise sub-microsecond timing information in today’s data center networks. In addition, the QFX5220 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.
    • Data packet timestamping*: When the optional data packet timestamping feature is enabled, selected packets flowing through QFX5220 switches are timestamped with references to the recovered PTP clock. When these packets are received by nodes in the network, the packet timestamping information can be mirrored onto monitoring tools for detailed analysis, helping identify bottlenecks in the network that cause latency. This information also helps with network performance analysis and record keeping for legal and compliance purposes, which is required by certain business transactions such as financial trading, video streaming, and research establishments.
    • RoCEv2: As a switch capable of transporting data as well as storage traffic over Ethernet, the QFX5220 provides an IEEE data center bridging (DCB) converged network between servers with disaggregated flash storage arrays or an NVMe-enabled storage area network (SAN). The QFX5220 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. The RDMA over Converged Ethernet version 2 (RoCEv2) transit switch functionality, including priority-based flow control (PFC) and Data Center Bridging Capability Exchange (DCBX), are included as part of the default software.
    • Junos OS Evolved: Junos 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 having to bring down the entire device.
    • 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, Juniper Extension Toolkit (JET), Junos Telemetry Interface (JTI), and the underlying data models, resemble those supported by Junos. This ensures compatibility and eases the transition to Junos Evolved. 

    Junos Telemetry Interface

    The QFX5220 supports Junos Telemetry Interface (JTI), 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. JTI 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.

It supports high numbers of egress IPv4/IPv6 rules by programming matches in egress ternary content addressable memory (TCAM) along with ingress TCAM.  

    132MB Shared Packet Buffer

    Today’s cloud-native applications have critical dependency on buffer size to prevent congestion and packet drops. The QFX5700 has 132 MB shared packet buffer that is allocated dynamically to congested ports.  

    Programmability

    The QFX5700 revolutionizes performance for data center networks by providing a programmable software-defined pipeline in addition to the comprehensive feature set provided in the Juniper Networks QFX5120 Switch line. The QFX5700 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.  

    Power Efficiency

    With its low power 7nm technology, a fully loaded and fully redundant QFX5700 consumes typically 2,870 W, bringing improvements in speed, less power consumption, and higher density on chip.  

    Features and Benefits

    • Automation and programmability: The QFX5700 supports several 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.
    • Cloud-level scale and performance: The QFX5700 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 QFX5700 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 exactly match filtering rules. The QFX5700 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 QFX5700 to be optimized for different deployment scenarios.
    • VXLAN overlays*: The QFX5700 is capable of both L2 and L3 gateway services. Customers can deploy overlay networks to provide L2 adjacencies for applications over L3 fabrics. The overlay networks use VXLAN in the data plane and EVPN or Open vSwitch Database (OVSDB) 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 QFX5700, enabling accurate and precise sub-microsecond timing information in today’s data center networks. In addition, the QFX5700 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.
    • Data packet timestamping*: When the optional data packet timestamping feature is enabled, select packets flowing through the QFX5700 are timestamped with references to the recovered PTP clock. When these packets are received by nodes in the network, the timestamping information can be mirrored onto monitoring tools to identify network bottlenecks that cause latency. This analysis can also be used for legal and compliance purposes in institutions such as financial trading, video streaming, and research establishments.
    • RoCEv2*: As a switch capable of transporting data as well as storage traffic over Ethernet, the QFX5700 provides an IEEE data center bridging (DCB) converged network between servers with disaggregated flash storage arrays or an NVMe-enabled storage-area network (SAN). The QFX5700 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. The RDMA over Converged Ethernet version 2 (RoCEv2) transit switch functionality, including priority-based flow control (PFC) and Data Center Bridging Capability Exchange (DCBX), are included as part of the default software.
    • Junos Evolved features: The QFX5700 switch 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 having to bring down the entire device. The switches 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.
