Juniper QFX Series QFX5210 Switch

The QFX5210 Switch provides line-rate, low-latency platforms for building large, standards-based fabrics. It offers flexible 10GbE, 25GbE, 40GbE, and 100GbE interfaces for server and intra-fabric connectivity. The QFX5210 is an optimal choice for lean spine-and-leaf deployments in enterprise, service provider, and cloud provider data centers, as well as routing use cases in metro environments.

This platform supports Juniper’s SONiC implementation, delivering best-of-breed hardware and routing while taking advantage of the flexibility, resiliency, and cost savings of SONiC’s open and disaggregated architecture.

Manage your QFX5210 with turnkey Juniper Apstra software, which automates the entire network lifecycle to simplify design, deployment, and operations and provides closed-loop assurance.

Key Features

Use Case: DC fabric leaf/spine

Port Density:

QFX5210-64C/-S: 64 x 40/100GbE QSFP+/QSFP28

Throughput: Up to 12.8 Tbps (bidirectional)

SONiC: ONIE and SONiC images preinstalled on QFX5210-64C-S

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.

Features + Benefits
