Q
What is the Juniper QFX3000 Series switch?
A
The Juniper QFX3000 Series is a high-performance, low-latency data center switch family designed for leaf-and-spine architectures, delivering scalable 10/25/40/100 GbE connectivity with advanced VXLAN EVPN support.
Q
Which key performance metrics define the QFX3000 Series?
A
The QFX3000 Series offers up to 2.56 Tbps switching capacity, sub-500 ns port-to-port latency, and up to 2.4 billion packets per second (bpps), ensuring wire-speed forwarding in demanding environments.
Q
What port densities and speeds are available on QFX3000 models?
A
Models support mixed 10/25/40/50/100 GbE QSFP28, SFP28, and QSFP+ interfaces, with up to 32 x 100 GbE or 96 x 25 GbE ports per chassis, enabling flexible top-of-rack deployments.
Q
How does the QFX3000 Series support network virtualization?
A
It natively supports EVPN-VXLAN for multi-tenant overlay networks, network segmentation, and zero-touch provisioning, delivering scalable Layer 2 and Layer 3 virtualization with hardware-offload.
Q
Which use cases are ideal for Juniper QFX3000 switches?
A
The QFX3000 Series is optimized for leaf-and-spine fabrics, high-density top-of-rack, scale-out Cloud deployments, NFV infrastructure, and high-performance computing clusters.
Q
What software powers the QFX3000 Series?
A
Juniper QFX3000 runs Junos OS with modular Control Plane, rich telemetry features, Zero Trust security policies, and automation support via PyEZ, Ansible, REST, and gNMI.
Q
How do you manage and automate QFX3000 switches?
A
Management options include Junos CLI, Junos Space, Juniper Apstra, Ansible playbooks, REST APIs, NETCONF, and open-source tools for centralized configuration and telemetry.
Q
What high-availability features are built into the QFX3000?
A
The series supports Virtual Chassis, ISSU (In-Service Software Upgrade), redundant power supplies, and front-to-back or back-to-front airflow for uninterrupted operations.
Q
How does Virtual Chassis simplify network scaling?
A
Virtual Chassis bundles up to 10 QFX3000 switches into a single logical device, providing unified management, distributed control plane, and linear scaling of ports and throughput.
Q
What security capabilities does the QFX3000 Series offer?
A
It delivers MACsec encryption, RADIUS/TACACS+ authentication, role-based access control, Dynamic ARP Inspection, DHCP Snooping, and integrated DDoS protection at line rate.
Q
How energy-efficient is the QFX3000 Series?
A
With 60 W per 100 GbE port and an industry-leading power-per-GbE ratio, advanced cooling modules, and intelligent fan control, the QFX3000 minimizes operational costs.
Q
What topology options are supported by QFX3000 switches?
A
They support traditional Layer 2/3 fabrics, spine-leaf, collapsed-spine, DCI (Data Center Interconnect) over EVPN, and routed network topologies with MLAG for redundancy.
Q
How do I deploy QFX3000 in a spine-leaf architecture?
A
Connect leaf switches directly to spine nodes using 25/100 GbE uplinks, enable EVPN-VXLAN underlay and overlay, configure MLAG on leaf pairs for dual-homed host resilience.
Q
What monitoring and telemetry features are available?
A
QFX3000 provides Junos Telemetry Interface (JTI), sFlow, IP-FIX, SNMP, and streaming analytics for real-time performance monitoring, anomaly detection, and capacity planning.
Q
Which power and cooling configurations does QFX3000 support?
A
Available with front-to-back or back-to-front airflow, hot-swappable dual AC/DC power supplies, and redundant variable-speed fans to meet data center airflow requirements.
Q
What support and software maintenance options are available?
A
Juniper offers Foundation, Core, and Premium Care support services, along with Junos OS software bundles, SLAs for hardware replacement, and Junos upgrade licenses for feature access.
