About the Arista 7280CR3K 400G Peering and Edge Switch

The Arista 7280CR3K is a fixed-configuration Layer 2/3 switch engineered for carrier-grade peering and cloud edge environments requiring extreme port density in compact form factors. Launched in Q2 2024, the platform delivers 12.8 Tbps of switching fabric throughput via 32 ports of 400G QSFP-DD connectivity, eliminating oversubscription bottlenecks in IX (Internet Exchange) and colocation fabrics. The architecture employs Arista's proven CloudEOS operating system with integrated BGP, EVPN, and segment routing capabilities, enabling streamlined deployment in multi-vendor peering fabrics without external routing appliances.

Ideal for

  • Internet Exchange Point (IXP) backbone infrastructure handling symmetric 400G peer interconnections and route-server architecture
  • Cloud on-ramp gateways for hyperscalers connecting regional edge compute to central cloud regions via high-capacity DCI links
  • Colocation provider edge aggregation supporting dense tenant interconnect and DCI peering with minimal latency
  • Telecom operator backbone peering points consolidating multiple carrier handoff circuits into unified 400G fabric
  • Content Delivery Network (CDN) ingestion points aggregating traffic from distributed cache nodes to central processing
  • Data center interconnect (DCI) leaf switches in stretched L2/L3 fabric topologies for multi-site disaster recovery
