Juniper QFX5120-48Y-AFI2 | QFX5120 48-Port 25GbE Switch, 8x 100G QSFP28

Q: What deployment scenarios is the QFX5120-48Y-AFI2 designed for?
A: The QFX5120-48Y-AFI2 is engineered for data center leaf-and-spine architectures, top-of-rack server access with 25GbE connectivity, campus distribution switching, and EVPN-VXLAN overlay networks. Its high-density port configuration supports modern cloud and virtualization workloads.

Q: Can the QSFP28 uplink ports be broken out into lower-speed ports?
A: Yes, each 100GbE QSFP28 port can be broken out into four 25GbE SFP28 ports, and each 40GbE QSFP+ port can be broken out into four 10GbE SFP+ ports using breakout cables, increasing total port count to 80 lower-speed ports for added flexibility.

Q: What does the AFI2 designation indicate?
A: AFI2 indicates back-to-front airflow configuration (port-side intake, PSU-side exhaust) with AC power supplies. This airflow direction is designed for cold-aisle containment data center environments and must be matched with compatible accessories and adjacent equipment.

Q: What advanced switching features does the QFX5120-48Y support?
A: The QFX5120-48Y supports EVPN-VXLAN overlays with L2/L3 gateway capabilities, MC-LAG for active-active server dual-homing, comprehensive Layer 3 routing protocols including BGP, OSPF, and IS-IS, hardware-accelerated ACLs, and Virtual Chassis stacking up to 2 members.

Q: Is the QFX5120-48Y-AFI2 compatible with Juniper automation tools?
A: Yes, the switch runs Junos OS and supports modern automation frameworks including Zero Touch Provisioning, Python scripting, Ansible integration, REST APIs, NETCONF, gRPC, OpenConfig, and Juniper Telemetry Interface for programmable network operations.
