A
With EVPN-VXLAN, MLAG, and BGP-EVPN control plane support, the QFX5200 provides scalable, loop-free, high-availability leaf-and-spine fabric for modern data centers.
Q
What virtualization and automation capabilities does the QFX5200 support?
A
The QFX5200 supports EVPN-VXLAN overlays, SR-TE, container firewalls, and programmable interfaces for Ansible, Chef, Puppet, and native Juniper automation frameworks.
Q
How does the QFX5200 deliver low latency and high throughput?
A
Leveraging Juniper’s Trio ASIC with cut-through switching delivers deterministic sub-microsecond latency and up to 51.2 Tbps of non-blocking throughput per device.
Q
What power and cooling options are offered on the QFX5200 Series?
A
The QFX5200 features redundant, hot-swappable PSU and fan trays, supports front-to-back or back-to-front airflow, and offers AC or DC power supplies to match data center designs.
Q
How scalable is the QFX5200 Series for future growth?
A
With flexible optics, modular traffic profiles, and EVPN-VXLAN fabric expansion, you can scale port count, speed, and virtualization layers without forklift upgrades.
Q
Can the QFX5200 support EVPN-VXLAN overlays?
A
Yes, the QFX5200 fully supports EVPN-VXLAN as both leaf and spine, enabling multi-tenant segmentation, seamless VM mobility, and simplified east-west traffic routing.
Q
What management and monitoring tools integrate with QFX5200?
A
The QFX5200 integrates with Juniper’s Junos Telemetry Interface, Junos Space, Contrail, AppFormix, and third-party tools via open APIs for real-time analytics and lifecycle management.
Q
How does the QFX5200 ensure high availability and redundancy?
A
High availability is achieved through MLAG, active-active fabric roles, redundant power and fans, non-stop software upgrades, and stateful In-Service Software Upgrade (ISSU).
Q
What security features are built into the QFX5200 Series?
A
QFX5200 offers MACsec encryption, dynamic ACLs, DDoS protection, role-based access control, secure boot, and Junos OS kernel integrity checks for end-to-end data center security.
Q
How does Juniper support and warranty the QFX5200 Series?
A
Juniper provides a 90-day software warranty, one-year hardware warranty, with options for Enhanced Care, Advanced Care, and Software Advantage to ensure rapid remediation and updates.
Q
What deployment considerations should be made for cloud environments?
A
Plan for VXLAN overlay addressing, BGP-EVPN control plane, spine uplink oversubscription, power/cooling capacity, and integration with orchestration frameworks like Kubernetes or OpenStack.
Q
How does the QFX5200 compare to earlier QFX Series switches?
A
Compared to prior QFX models, the QFX5200 offers higher port densities, native 400GbE support, improved latency, enhanced telemetry, and deeper automation integration for modern fabrics.
