Juniper QFX5120-48T-AFI-T

The QFX5120 Ethernet Switch delivers rich, low latency Layer 2/Layer 3 (L2/L3) features and advanced EVPN-VXLAN capabilities, making it an ideal data center top-of-rack and aggregation switch for enterprise multicloud deployments. Featuring L3 gateway capabilities for routing between virtualized and bare-metal servers, the QFX5120 is designed for extremely agile data centers that require support for overlay/underlay network architectures. Native 25GbE with 100GbE uplink ports on the QFX5120-48Y, 10GbE copper with 100GbE uplink ports on the QFX5120-48T, and 32 100GbE ports on the QFX5120-32C make the QFX5120 family ideal for spineand- leaf network deployments.

Product Description

Featuring L3 gateway capabilities for routing between virtualized and bare-metal servers, the high-performance Juniper Networks® QFX5120 Ethernet Switch provides the ideal foundation for dynamic data centers. Native 25GbE fiber ports on the QFX5120-48Y and 10GbE copper ports on the QFX5120-48T satisfy the growing demand for server access speeds, while high-density fixed-configuration 100GbE ports on the QFX5120-32C satisfy the need for compact, lower power devices in the spine. The QFX5120 is packed with software features that support traditional fabric designs with multichassis link aggregation (MC-LAG) or evolving SDN architectures with Ethernet VPN (EVPN)/Virtual Extensible LAN (VXLAN) on IP fabric underlays.

Architecture and Key Components

The QFX5120, which includes rich L2, L3, EVPN, and MPLS features, runs the same reliable, high-performance Junos® operating system used by all Juniper Networks QFX Series and EX Series Ethernet Switches, Juniper Networks SRX Series Services Gateways, and Juniper Networks routers, ensuring a consistent control plane feature implementation and user experience across the entire Juniper infrastructure.

Product Options

The QFX5120 switch family includes three compact, 1 U platforms that provide wire-speed packet performance, very low latency, and a rich set of Junos OS features:

  • The QFX5120-48Y is a 25GbE/100GbE data center access switch offering 48 small form-factor pluggable plus (SFP+) transceiver ports and eight quad SFP (QSFP28/ QSFP+) ports that can be configured as 8x40GbE or 8x100GbE ports. For added flexibility, each QSFP28 port can also be configured as 4x25GbE ports using breakout cables, while each QSFP+ port can be configured as 4x10GbE ports using breakout cables, increasing the number of supported 25GbE and 10GbE ports per switch to 80.
  • The QFX5120-48T is a 10GbE/100GbE data center access switch offering 48 10GbE RJ-45 copper ports and six 100GbE/40GbE QSFP28/QSFP+ uplink ports. With dualspeed (1GbE/10GbE) capabilities on all 48 host ports and 40GbE/100GbE on the uplink ports, the QFX5120-48T can be deployed as an access switch with a combination of 48 1GbE/10GbE ports for downlink servers and storage conne
