ADVANCED FEATURES:

EVPN-VXLAN for Scalable Overlays:

The DCS-7050QX-32S-R supports EVPN-VXLAN, enabling scalable Layer 2 and Layer 3 overlays across data center, campus, and hybrid cloud environments. This feature allows administrators to create isolated, multi-tenant networks while maintaining consistent policies. Workload mobility is simplified, enabling virtual machines and containers to move freely without requiring VLAN reconfiguration. EVPN-VXLAN also improves operational efficiency by centralizing control, reducing network complexity, and allowing flexible expansion as enterprise needs grow.

MLAG and High-Availability Architecture:

Multi-Chassis Link Aggregation (MLAG) allows the DCS-7050QX-32S-R to provide active-active uplink redundancy between switches. Paired with dual hot-swappable power supplies and redundant fan trays, the switch offers seamless failover during hardware or link failures, ensuring continuous operation for critical applications. MLAG also supports load balancing across physical links, optimizing bandwidth utilization and enhancing network resiliency.

Flexible High-Speed Uplinks:

Equipped with 32 × 40GbE SFP28 ports, the switch delivers high-speed connectivity for demanding environments. These uplinks are ideal for data center cores, aggregation layers, or high-throughput enterprise applications. Multiple breakout options allow the ports to be divided into smaller interfaces as needed, providing investment protection and future-proofing the network against growing bandwidth demands.

Arista EOS Automation and Programmability:

The switch runs on Arista EOS (Extensible Operating System), providing industry-leading automation, programmability, and telemetry capabilities. Administrators can leverage Zero-Touch Provisioning (ZTP), scripting, and REST APIs to automate deployment, configuration, and software updates. EOS’s open architecture allows integration with third-party orchestration tools, improving operational efficiency, reducing human errors, and accelerating network provisioning.

Advanced Telemetry and Monitoring:

Supports high-frequency streaming telemetry, sFlow, IPFIX, and other monitoring protocols for real-time visibility into traffic flows, network health, and performance. Operators can proactively detect congestion, monitor application behavior, and perform predictive capacity planning. This detailed visibility enables rapid troubleshooting, SLA compliance, and enhanced overall network reliability.

Comprehensive Quality of Service (QoS):

With eight hardware queues per port, traffic shaping, congestion management, and prioritization of latency-sensitive traffic, the DCS-7050QX-32S-R ensures optimal performance for critical applications such as voice, video conferencing, and financial trading systems. Administrators can fine-tune traffic policies to meet service level agreements and deliver consistent performance even under heavy network load.

Enterprise-Grade Security:

Security is embedded at every layer of the switch. Features include line-rate MACsec encryption, 802.1X authentication, DHCP snooping, IP Source Guard, and Dynamic ARP Inspection (DAI). Role-based access control is enforced via RADIUS, TACACS+, and SNMPv3, ensuring only authorized users can access the network. Together, these capabilities protect against unauthorized access, man-in-the-middle attacks, and other common threats, maintaining enterprise-grade security across all deployments.

Energy-Efficient and Eco-Friendly Design:

The switch is optimized for power efficiency, with intelligent fan and power management that dynamically adjusts consumption based on load. This reduces operational costs and supports sustainability initiatives. Compact 1U form factor allows dense deployment in racks, making it ideal for environments with space or power constraints.

Cloud-Ready Management and Integration:

The DCS-7050QX-32S-R integrates seamlessly with Arista CloudVision and third-party network management platforms, providing centralized configuration, monitoring, and telemetry. IT teams gain actionable insights, predictive analytics, and automated remediation capabilities. Cloud-ready management simplifies large-scale deployments, reduces manual effort, and ensures consistent policy enforcement across distributed networks.

High Availability and Fault Tolerance:

Designed for mission-critical environments, the switch supports redundant power supplies, hot-swappable fans, and MLAG failover, ensuring uninterrupted network operation. Combined with low-latency wire-speed forwarding, it provides a highly resilient solution for enterprise, campus, and data center networks where downtime is not an option.

Flexible Deployment Options:

With configurable airflow (front-to-back or back-to-front), modular uplinks, and compact 1U design, the DCS-7050QX-32S-R can be deployed in a variety of environments, including high-density racks, wiring closets, and distributed campus or data center networks.
