Our take on the Juniper QFX5100-96S-AFI-T Layer 3 Network Switch

The QFX5100-96S is a 1 RU data center switch with 96 SFP+ ports running at 10G, plus 8 QSFP+ ports for 40G uplinks. It switches at up to 2.56 Tbps and handles both Layer 2 and Layer 3, which puts it in the spine-leaf class rather than the office closet. It is fiber-only and does not power devices over Ethernet, so it suits data center and service provider racks, not desks. Against 48-port 10G rivals it doubles port density in the same rack space, but it is louder, hungrier and far more expensive than edge switches, and Juniper's current QFX5120 line is the newer alternative.

What reviewers say

Owners treat it as a workhorse for dense 10G fabrics and praise its throughput and Junos consistency. Complaints center on fan noise, heat and the learning curve for teams new to Junos.

What people mention
  • ThroughputPraisedOwners report line-rate 10G across all ports with no drops under load.
  • NoiseCriticisedFans run loud; it belongs in a data center, not an office or lab bench.
  • HeatCriticisedThe unit draws heavy power and needs strong front-to-back airflow.
  • JunosMixedPowerful and consistent once learned, but steep for engineers raised on other CLIs.
  • Port densityPraised96 10G ports in 1 RU saves rack space in dense leaf deployments.

Questions and answers

Does the QFX5100-96S have copper ports?
No. All 96 access ports are SFP+ cages for fiber or DAC cables. There are no RJ45 copper ports and no PoE.

Yes. It runs Layer 2 and Layer 3 in Junos, including OSPF, BGP and VXLAN EVPN on supported releases.
How does it compare with the QFX5120?
The QFX5120 is the newer generation with similar density and better power efficiency. The QFX5100-96S is the older, cheaper-on-the-secondary-market option.
What is in the box?
The switch, rack-mount brackets and at least one power supply. Check that both PSUs and fan trays are included before buying used.
