Juniper QFX5110-48S-AFI2 48-port network switch 48*SFP+ and 4*QSFP28, back to front air flow, AC QFX5110 access and aggregation switch

Description

48 SFP+ and 4 QSFP28, back to front air flow, AC

QFX5110 access and aggregation switches deliver low latency, rich Layer 2 and Layer 3 features, VXLAN overlay deployments, and 100GbE uplinks, making it the industrys most nimble line of switches.

Featuring L3 gateway capabilities for bridging between virtualized and bare-metal servers, the QFX5110 is designed for extremely agile data centers that demand support for overlay/underlay network architectures. The high-density 10GbE, 40GbE, and 100GbE ports also make the QFX5110 ideally suited for use in data center spine and leaf topologies and campus distribution.

QFX5110 highlights:
Support high-density, multi-speed configurations for 10/40/100GbE access and aggregation, with up to 64 or 96 10GbE ports, up to four 100GbE uplink ports, and up to 32 40GbE ports in a 1 U platform

Deliver up to 2.56 Tbps Layer 2 and Layer 3 performance, with latency as low as 550 nanoseconds

Include a 1.8 GHz quad-core Intel CPU with 16 GB memory and 64 GB SSD storage

Feature rich automation capabilities with support for Python and zero touch provisioning (ZTP)
Support virtualization protocols such as Virtual Extensible LAN (VXLAN) and Open vSwitch Database (OVSDB) protocol as L2 Gateway or L3 Gateway

Offer advanced Junos OS features such as BGP add-path, MPLS, L3 VPN, and IPv6 6PE
