Overview
QFX5120 Switches offer 1 U, 1/10/25/40/100GbE fixed configuration for data centers and campus deployments. Cloud services require higher network bandwidth per rack, making 10GbE, 25GbE and 100GbE the dominant port speeds.
Coupled with the widespread adoption of overlay technologies, the QFX5120 lays a strong infrastructure foundation for your evolving business and network needs.
The switch 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 (VXLAN) on IP fabric underlays.
Juniper’s Apstra solution provides a comprehensive fabric management solution, providing intent-driven automation for deployment along with robust monitoring for assured operation.
The QFX5120 is ideal for data center and campus deployments and comes in four models:
- QFX5120-48T: data center leaf or campus distribution switch with 48 x 1/10GbE RJ-45 and 6 x 40/100GbE ports
- QFX5120-48Y: data center leaf or campus distribution switch with 48 x 1/10/25GbE and 8 x 40/100GbE ports
- QFX5120-48YM: data center leaf or campus distribution switch with 48 x 1/10/25GbE and 8 x 40/100GbE ports, and MACsec with AES-256 encryption across all ports
- QFX5120-32C: compact data center leaf/spine or campus distribution/core switch with 32 x 100GbE ports
