Engineering Simplicity QFX5210 SWITCH Product Overview The QFX5210 is a flexible, 64-port, fixed-configuration switch 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, 50GbE, and 100GbE interfaces for IP fabric networks, providing deployment versatility, investment protection, and futureproofing for today's data centers. The QFX5210 Switch's high port density also contributes to simplified Clos architectures, eliminating network tiers while reducin complexity and cost. designed for spine-and-leaf applications in next-generation IP fabric networks. Featuring line-rate, high-density QSFP+/ QSFP28 ports supporting 10GbE, 25GbE, 40GbE, 50GbE, and 100GbE connections, the Like other QFX Series switches, the QFX5210 supports advanced Layer 2, Layer 3, and MPLS features. For large public cloud providers—among the first to adopt 25GbE and 50GbE 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 Juniper Networks Junos® operating system used by network operators around the world. QFX5210 offers an advanced L2, L3, and MPLS feature set. This allows network operators to build large, high-density IP fabrics that support network virtualization and intelligent traffic forwarding 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 based on proven, Internet-scale technology, while enabling easy upgrades to 25GbE and 50GbE servers. Port Combinations The QFX5210 can be positioned as a top-of-rack device in a centralized gateway architecture. 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 Virtual Extensible LAN (VXLAN), MPLS, and other tunneling protocols. The 100GbE ports on the QFX5210 can be channelized to support 2x50GbE, 4x25GbE, or 4x10GbE downlinks.

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.

Contrail Networking The QFX5210 switches can be managed with Juniper Networks Contrail Networking, a fabric management and SDN overlay solution that provides full lifecycle management for both data center and data center interconnect infrastructures. Contrail Networking automates data center operations so users can focus on revenue-generating services rather than operational networking procedures. Contrail Networking works with any standard IP Clos architecture, performing configuration operations across virtual networks and physical devices by leveraging open protocols such as NETCONF/RPC.

(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 labelswitching router (LSR) or MPLS provider edge (PE) router in smaller scale environments. The QFX5210, along with the Juniper Networks QFX5200, QFX5110, and QFX5100 switches, is among the industry’s...
