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.
