Juniper QFX5120-32C-AFO 32x100GbE Switch with 2x AC Airflow

Overview

The QFX5120 Switch includes four compact 1 U platforms that provide wire-speed packet performance, very low latency, and a rich set of Junos operating system features.

TThe QFX5120-32C is a compact 100GbE data center leaf-and-spine and campus distribution switch featuring:

• 32 100GbE (QSFP28) or 40GbE (QSFP+) uplink ports
• A 2.2 GHz quad-core Intel CPU with 16 GB memory and 64 GB SSD storage
• Up to 6.4 Tbps L2 and L3 performance (bidirectional), with latency as low as 550 nanoseconds

Using breakout cables, each 100GbE QSFP28 port can be broken into four 25GbE SFP28 ports and each 40GbE QSFP+ port can be broken into four 10GbE SFP+ ports, increasing the total number of 25GbE and 10GbE ports per switch to 128.

In addition, QFX5120 switch models include:

• Support for VXLAN as an L2 or L3 gateway
• Advanced Junos OS features such as Ethernet VPN-Virtual Extensible LAN (EVPN-VXLAN), BGP add-path, L3 VPN, and MPLS
• Feature-rich automation capabilities with support for Python and zero-touch provisioning (ZTP)
