Arista 7050CX4M-48D8 – 48 × 100G QSFP28, 8 × 400G QSFP-DD, Modular 1U Data Centre Switch with Layer 2/3/4 Support

Arista DCS-7050CX4M-48D8 is a 2RU high-density, next-generation data centre switch that combines 48 × 100G QSFP28 ports with 8 × 400G QSFP-DD uplinks, delivering an aggregate throughput of up to 8.0 Tbps. Designed for top-of-rack and spine deployments, this system supports MACsec encryption for secure data centre fabrics.

Each 100G QSFP28 port supports flexible breakout configurations (100G, 50G, 25G, 10G), while each 400G QSFP-DD uplink supports 400G, 200G, 100G, and 40G modes, enabling up to 72 logical ports for versatile high-performance connectivity. Optimised for cloud, hyperscale, and enterprise environments, the 7050CX4M-48D8 delivers ultra-low latency, high-availability features, and seamless integration with VXLAN/EVPN, CloudVision telemetry, and automation frameworks.

ADVANCED FEATURES:

Layer 2 & Layer 3 Switching: 

Full support for VLANs, Private VLANs (PVLANs), Link Aggregation (LACP), VRF, and inter-VLAN routing. These features ensure secure, flexible traffic segmentation, optimal load balancing, and high-performance packet forwarding across enterprise and hyperscale data centre environments.

Layer 4 Support: 

Comprehensive L4 ACLs provide traffic filtering, prioritisation, and rate-limiting based on TCP/UDP ports. Supports critical enterprise and cloud applications, including HTTP, HTTPS, VoIP, DNS, and custom service flows, giving administrators granular control over application-level traffic.

Virtualisation: 

VXLAN and EVPN with hardware acceleration enable scalable multi-tenant and cloud-ready networks. Extends Layer 2 over Layer 3 fabric, provides redundancy, seamless workload migration, and supports dynamic, automated provisioning of virtualised networks.

High Availability:

Designed for mission-critical deployments with MLAG, redundant hot-swappable fans and power supplies, hitless software upgrades (ISSU), and rapid failover mechanisms to maintain continuous uptime and network resilience.

Quality of Service (QoS): 

Each port supports eight hardware queues, enabling traffic shaping, rate-limiting, and priority queuing. Ensures deterministic performance for latency-sensitive applications such as voice, video conferencing, streaming, HPC workloads, and real-time analytics.

Telemetry & Analytics: 

Advanced monitoring with sFlow, LANZ, microburst detection, and real-time streaming telemetry. Integration with Arista CloudVision allows centralised visibility, predictive analytics, performance trending, automated alerts, and proactive congestion management.

Automation & Programmability: 

Supports Zero-Touch Provisioning (ZTP), eAPI, Python scripting, OpenConfig, and DevOps/NetOps workflows. Enables automated provisioning, policy enforcement, configuration management, and integration with orchestration and management platforms for fast, error-free network operations.

Security Enhancements: 

Enterprise-grade security includes L2/L3/L4 ACLs, 802.1X authentication, DHCP snooping, IP Source Guard, dynamic ARP inspection, MACsec encryption on supported ports, and Control Plane Policing (CoPP). Protects against unauthorised access, rogue devices, and malicious traffic while maintaining compliance with corporate security policies.

Energy Efficiency: 

Intelligent fan control, optimised airflow, low-power design, and high-density architecture reduce operating costs while sustaining performance. Suitable for large-scale, energy-conscious data centres and cloud deployments.

Scalability & Flexibility: 

Supports flexible port breakouts, multiple uplink configurations, and programmable forwarding pipelines. Ideal for spine-leaf topologies, top-of-rack deployments, and cloud-scale multi-tenant networks.

Operational Excellence: 

Integration with Arista CloudVision and EOS ensures seamless automation, telemetry, troubleshooting, and lifecycle management, reducing operational complexity and improving network uptime.
