The QFX5120 Switch supports 1GbE, 10GbE, 25GbE, 40GbE, and 100GbE interfaces, including models with 1GbE/10GbE copper options, for data center, data center interconnect, and campus deployments. The QFX5120 is packed with software features that support modern EVPN-VXLAN fabric architectures.
Manage your data center QFX5120 Switch deployment with turnkey Juniper Apstra software, which automates the entire network lifecycle to simplify design, deployment, and operations and provides closed-loop assurance. Deploy and manage your campus fabric from the Juniper Mist cloud to streamline operations and improve visibility.
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 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.
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 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.
