ADVANCED FEATURES:

Layer 2 & Layer 3 Switching:

The 7050CX3-32C delivers comprehensive Layer 2 and Layer 3 switching capabilities suitable for both data center and campus aggregation networks. At Layer 2, it supports advanced VLAN segmentation, private VLANs, link aggregation (LACP), and rapid spanning tree protocols for robust and loop-free topology. At Layer 3, the switch enables inter-VLAN routing, static and dynamic routing protocols, and VRF instances, allowing multiple isolated routing domains within the same physical infrastructure. This combination ensures predictable, low-latency packet forwarding even under high-throughput conditions and provides the flexibility to design complex, multi-tenant network environments.

Virtualisation with EVPN & VXLAN:

The 7050CX3-32C is built to simplify modern network virtualisation. By supporting VXLAN and EVPN, it allows Layer 2 networks to extend seamlessly over Layer 3 infrastructures, reducing the need for complex reconfigurations across distributed sites. EVPN enhances MAC/IP learning, optimises routing paths, and improves redundancy, providing a resilient and scalable network fabric. This capability makes the switch ideal for cloud-ready deployments, hyper-converged infrastructure, and virtualised campus environments, while supporting seamless multi-site connectivity and workload mobility.

High Availability & Resilience:

Arista prioritises uptime and operational continuity. The 7050CX3-32C features MLAG (Multi-Chassis Link Aggregation) for link redundancy across multiple switches, along with dual hot-swappable power supplies and hot-swappable fans to ensure uninterrupted operation during maintenance or hardware replacement. Stateful Software Upgrades (SSU) and Stateful Fault Repair (SFR) allow configuration changes and software updates without network downtime, making it a reliable choice for mission-critical applications, cloud services, and latency-sensitive workloads.

Advanced Quality of Service (QoS):

The switch offers comprehensive QoS capabilities, including eight queues per port, traffic shaping, priority marking using CoS and DSCP, and fine-grained bandwidth allocation. These features prioritise latency-sensitive traffic such as high-performance computing, HD video, VoIP, and real-time analytics, while maintaining fairness across all connected devices. Administrators can implement granular policies to optimise application performance, prevent congestion, and ensure predictable service levels across the entire network.

Telemetry & Network Analytics:

Integrated telemetry technologies, including sFlow, IPFIX, and FlowTracker, enable continuous monitoring of traffic flows, bandwidth utilisation, and congestion points. When combined with Arista CloudVision, the switch provides centralised network visibility, predictive capacity planning, automated anomaly detection, and faster troubleshooting. This allows administrators to proactively identify performance bottlenecks, optimise resource usage, and maintain high operational efficiency across distributed data center or campus environments.

Automation & Programmability:

Arista EOS offers a programmable and scriptable platform, supporting automation through Python, Bash, Go, C++, and the EOS SDK. Network administrators can automate provisioning, monitoring, and maintenance tasks, reducing manual configuration errors and operational overhead. Integration with Arista CloudVision allows policy-driven automation, consistent configuration deployment, compliance enforcement, and network-wide orchestration. This enhances agility in large-scale deployments and simplifies network lifecycle management for IT teams.

Security & Access Control:

The 7050CX3-32C includes comprehensive security measures to protect both the network and its connected devices. Features include IEEE 802.1X authentication, MAC-based access control, DHCP snooping, IP source guard, dynamic ARP inspection, and hardware-based ACLs for Layer 2–Layer 4 traffic filtering. Storm control, Control Plane Policing (CoPP), and role-based access control (RBAC) help safeguard the control plane and prevent malicious traffic floods, ensuring secure and stable network operations.

Energy Efficiency & Sustainability:

Energy efficiency is embedded in the design of the 7050CX3-32C. Intelligent power management allocates power dynamically across ports, while optimised fan control adjusts cooling based on thermal load. Front-to-rear airflow enhances heat dissipation, reducing energy consumption without impacting performance. These features not only lower operational costs but also support sustainable IT practices by minimising environmental impact, making it suitable for energy-conscious data centers and enterprise networks.
