Product Description

QFX5120-48Y-AFO2

The Juniper Networks® QFX5120 Switch delivers high scale, high availability, and high performance for data center and campus deployments. The QFX5120 Switch is a versatile routing and switching platform addressing higher server access speed and campus distribution use cases while offering high-density 1GbE/10GbE/25GbE and 100GbE uplinks for collapsed spine data center or campus distribution deployments.

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 291,000 MAC addresses. In L3 mode, the QFX5120 table can support 211,000 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.

Virtual chassis

The QFX5120 supports Juniper Networks’ unique virtual chassis technology, which enables 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), QFX5120-48T (starting with Junos 20.2), and QFX5120-48YM (starting with Junos 23.1) support virtual chassis feature.

QFX5120-48T, QFX5120-48Y, and QFX5120-32C switche models support HiGig protocol for forming a virtual chassis. However, the QFX5120-48YM switch model supports only HGoE protocol for virtual chassis formation.

Product overview

The QFX5120 Switch delivers rich, low latency Layer 2/Layer 3 features and advanced EVPN-VXLAN capabilities, making it an ideal data center top-of-rack and distribution switch for campus enterprise deployments.

Featuring L3 gateway capabilities for routing between virtualized and bare-metal servers, the QFX5120 is designed for extremely agile data center that require support for overlay/underlay network architectures. Native 25GbE with 100GbE uplink ports on the QFX5120-48Y and QFX5120-48YM, 10GbE/1GbE copper with 100GbE uplink ports on the QFX5120-48T, and 32 100GbE ports on the QFX5120-32C make the QFX5120 family ideal for spine-and-leaf network deployments.
