What is the port configuration and throughput of DCS-7280CR2M-30-F?

Features 30x QSFP100 ports supporting 30x100GbE or 30x40GbE, delivering 6Tbps full-duplex wire-speed throughput. Non-blocking architecture ensures all ports forward at line-rate simultaneously with 12GB shared buffers for congestion-free performance in high-fanout spine roles.

Does it support MACsec encryption and on which ports?

Built-in wire-speed MACsec encryption on all 30x 100GbE ports provides 802.1AE standards-compliant link-layer security without performance penalty, ideal for protecting east-west traffic in multi-tenant clouds or compliance environments.

What power and environmental specs does it support?

Dual hot-swappable AC (200-240V) or DC (-40-72V) PSUs with typical 1300W draw (max 1400W). Operates 0-40°C, up to 3000m altitude, 5-95% humidity in 1RU (19x1.7x26.4in, 34lbs) with N+1 redundant fans.

What advanced features for data center virtualization?

VXLAN bridging/routing with VRF/MLAG, VM Tracer for VMware integration, LANZ microburst detection, and IEEE 1588 PTP timing. Supports 32 ports/LAG, ETS/WFQ QoS, and sFlow for visibility in overlay networks.

How does it handle high-scale routing and L3?

Full L3 suite: OSPF/OSPFv3, BGP/MP-BGP, IS-IS, RIPv2 with static routes. Hardware-accelerated forwarding supports jumbo frames (9216B), IGMP snooping, and storm control for massive route tables in leaf-spine fabrics.

What management and monitoring capabilities?

EOS Linux-based OS with SNMPv3, SSHv2, Syslog, AAA, and industry CLI. Built-in SSD for logs/captures, Beacon LED, environment monitoring, and IPv6 management for automated, zero-touch provisioning.

Product overview

The Arista DCS-7280CR2M-30-F is a high-density 1RU data center switch purpose-built for cloud-scale networking, featuring 30x QSFP100 ports supporting 100GbE with built-in wire-speed MACsec encryption on every port for uncompromising security. It provides 6Tbps of non-blocking throughput and 12GB of deep packet buffers to handle microbursts and large data flows in congested environments. VoQ architecture with distributed scheduling ensures low-latency, lossless performance across L2/L3 features including VXLAN, EVPN, BGP, OSPF, and IS-IS. Configurable airflow, front-to-rear or back-to-front, supports diverse rack environments with dual AC/DC PSUs and hot-swappable fans. Management via EOS includes LANZ for microburst detection, sFlow, PTP, and VM Tracer for virtualization. Ideal for spine/leaf fabrics, HPC clusters, and secure IP storage networks requiring ultra-low latency and high port density in compact form factors.
