Juniper Networks QFX Series QFX5120-48T - Switch - L3 - managed - 48 x 1 Gigabit / 10 Gigabit Ethernet + 6 x 40/100 Gigabit QSFP28 - front to back airflow - rack-mountable - TAA Compliant
- Up to 48 10GbE RJ-45 copper ports and six 100GbE uplink ports in a 1U platform
- Up to 2.16Tbps L2 and L3 performance, with latency as low as 550 nanoseconds
- A powerful processor with 16GB memory and 100GB SSD storage
The QFX5120 Ethernet switch delivers rich, low-latency features and advanced capabilities, making it an ideal data center 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.
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 dual-speed 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 connectivity, and six 40GbE/100GbE ports for uplinks to spine switches.
-
Automation
The QFX5120 supports a number of network automation and Plug-and-Play operation features, including ZTP and event scripts, automatic rollback, and Python scripting.
-
Flexible forwarding table
The QFX5120 switch includes a unified forwarding table (UFT), which allows the hardware table to be carved into configurable partitions of L2 media access control (MAC), L3 host, and long prefix match (LPM) tables.
-
Intelligent buffer management
The QFX5120 features a total of 32MB 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, which can operate without a controller or be orchestrated with an SDN controller.
