As routed fabrics grow denser, infrastructure teams need to keep adding speed, segmentation and policy control without turning the network into a management burden.
The Arista 7280CR3K-32D4 is built for production environments that need high-scale routing at the edge of the data centre, across multi-site fabrics or in other policy-heavy designs. It combines 32×QSFP-DD and 4×QSFP-DD ports with 400G support, giving teams a compact platform for demanding interconnect and aggregation roles.
With 28,800 Gbps switching capacity and EOS, the platform is intended to support larger route tables and more complex policy environments while keeping operations consistent. That makes it easier to extend routed boundaries, maintain separation between domains and keep physical infrastructure aligned with application growth.
For infrastructure owners, the value is in preserving control as workloads expand. The switch router helps sustain high-speed connectivity, clearer segmentation and room for additional routes and policies, reducing pressure to redesign the fabric just to absorb growth.

The Arista 7280CR3K-32D4 is a high-density data center switching platform for modern network fabrics, designed to provide scalable connectivity and a strong foundation for demanding enterprise and cloud environments.
Large-Port Aggregate Design
The platform provides a high-density switching architecture with 32×QSFP-DD and 4×QSFP-DD ports for fabric aggregation.
400G Uplink Capability
Its QSFP-DD interface design supports up to 400G port speeds to align high-throughput links with modern data center fabric requirements.
Capacity for Scale-Out Networks
The switching design delivers 28,800 Gbps of switching capacity to support high-bandwidth east-west traffic patterns.
Data Center Fabric Role
The system is positioned as a core switching platform for environments that need dense, scalable interconnects across enterprise and cloud infrastructures.
Fabric-Oriented Operations
The platform is built for network fabric deployment, supporting consistent connectivity behavior across large-scale switching domains.
Infrastructure Simplification
A high-density port layout reduces the number of switch platforms needed to build aggregated connectivity layers.
Deployment Flexibility
The architecture supports use across new and refurbished variants without changing the underlying platform role.
If you are planning a high-density data center fabric, our team can help align port density, uplink speed, and switching capacity to your network design.

The Arista 7280CR3K-32D4 is a high-scale routed aggregation platform for environments where route tables, VRFs and policy state grow quickly, especially in multi-tenant fabrics, segmented finance estates, utility networks and telecom edge deployments.
In large data centres, this platform fits routed aggregation or DCI border roles where EVPN tenants and external routes outpace physical port growth. It helps operators keep routing control without forcing an early fabric redesign.
Finance teams can place it between trading, risk, payments and compliance domains when strict separation and fast interconnect are both required. The larger scale profile reduces the need to split route state across several smaller routers.
Energy and utilities estates use it to connect control centres, telemetry platforms, OT DMZs and analytics links while preserving domain separation. It suits teams that need visibility, large route tables and clearer control across sensitive systems.
For software development platforms, it supports private-cloud edges where many clusters, namespaces and test networks create constant routing churn. Platform teams gain a single boundary device that keeps tenant separation intact under automation-heavy operations.
Telecom operators can deploy it across NFV, packet-core and MEC aggregation layers where many service chains and customer domains share one fabric. Its scale profile supports dense routing without fragmenting the physical infrastructure.
Our team can help design and deploy Arista 7280CR3K-32D4 environments for routed aggregation, segmented networks, private-cloud edges and telecom service fabrics, with practical guidance on scale, separation and operational control.
