The Arista 7280CR3-32P4 is built for enterprise data centre leaf and edge aggregation where predictable traffic flow and clear routing boundaries matter. Its routing-optimised design and dynamic Layer 3 capability help teams move heavy traffic between racks or sites with less congestion.
As traffic grows across pods, sites and service zones, infrastructure teams need routed aggregation that can carry bursty flows cleanly without adding fabric complexity.
The Arista 7280CR3-32P4 is a leaf switch for production environments that need compact routing at the edge of the network. It suits data centres and other dense estates where 100GbE domains must be aggregated and moved into higher-capacity paths with predictable behaviour.
With 32×QSFP28 and 4×QSFP28 ports, the platform provides a straightforward way to connect server, storage and interconnect traffic into a single routing point. Its 7200 Gbps switching capacity supports high-volume east-west movement without forcing a redesign of the surrounding network.
That makes it a practical fit for leaf-spine, DCI and other environments where large flows need clearer boundaries, better buffering and a path towards higher-speed aggregation. It helps reduce congestion between racks or domains and gives network teams a cleaner place to manage scale.
Our team can help you evaluate the Arista 7280CR3-32P4 for your environment and align it to the routing, aggregation and uplink requirements of your production network.
The Arista 7280CR3-32P4 is a high-performance switching platform for data center network environments, providing a dense 100G architecture suited to demanding spine, aggregation, and high-bandwidth connectivity roles.
Dense QSFP28 Architecture
The platform provides 32×QSFP28 plus 4×QSFP28 ports for high-density 100G connectivity in compact data center designs.
Spine and Aggregation Fit
Its 100G port model supports high-bandwidth switching roles where predictable connectivity and scale are required.
High-Capacity Fabric Design
The switch delivers 7200 Gbps of switching capacity to support demanding east-west traffic patterns.
Flexible Uplink Placement
The QSFP28 port layout supports flexible network design for leaf-spine and aggregation architectures.
Platform-Oriented Deployment
The switch is positioned as a data center networking platform, supporting consistent architectural deployment across new and refurbished variants.
Predictable Traffic Handling
High-capacity 100G forwarding helps maintain consistent behaviour in bandwidth-intensive environments.
Infrastructure Alignment
The architecture is suited to environments that require dense interconnects and structured switching layers.
If you are planning a bandwidth-heavy data center network, our team can help align the 7280CR3-32P4 with your switching, density, and fabric design requirements.

The Arista 7280CR3-32P4 is a routed aggregation switch-router for data-centre, media, finance, software and telecoms environments that need to consolidate 100GbE domains into 400GbE uplinks. It fits teams carrying bursty east-west traffic, inter-site flows and storage-heavy workloads.
In multi-pod data centres, this platform aggregates leaf switches, storage islands and backup networks into fewer higher-speed paths. Teams use it where replication and inter-cluster traffic arrive in bursts and need more predictable movement across sites or domains.
Broadcast and post-production facilities can place it between edit rooms, render farms and central storage. It handles large file transfers leaving the local rack, helping keep shared media workflows moving when projects span rooms, studios or remote collaboration sites.
Financial infrastructure teams deploy it at the boundary between analytics, market-data and regulated service zones. It provides a stronger aggregation point for high-volume traffic crossing racks or sites, where a pure leaf switch is too narrow for the workload.
For software development estates, it consolidates Kubernetes, CI and storage leafs into a routed platform spine. This reduces shared-fabric bottlenecks and gives platform teams clearer boundaries for registries, artifact stores and test infrastructure across pods or locations.
Telecoms teams use it for packet-core, UPF and service-chain environments where 100GbE appliance clusters need higher-speed transport. It suits bursty lab and edge traffic, while supporting separation and monitoring across handoff points and regional aggregation layers.
Our team can help design and deploy Arista 7280CR3-32P4 in routed aggregation, interconnect and edge handoff roles, aligned to your traffic patterns, resilience targets and operational staffing model.
