What port configuration and speeds does the DCS-7280QRA-C36SM-R support?

Features 24x 40GbE QSFP+ ports and 12x 100GbE QSFP ports. QSFP+ supports 40GbE or breakout to 4x10GbE; QSFP100 supports 100/50/40/25/10GbE. Flexible combinations enable up to 144x10G, 48x25G, or 24x50G, ideal for mixed-speed data center fabrics.

What is the switching capacity and buffering of this Arista switch?

Provides 2.88Tbps full-duplex switching capacity with 16GB shared packet buffer. Virtual Output Queueing and distributed scheduling ensure non-blocking performance, handling microbursts and congestion in high-density spine/leaf deployments effectively.

Does it support advanced routing and overlay protocols?

Full Layer 3 suite: OSPF, BGP, MP-BGP, IS-IS, PIM-SM/SSM, Anycast RP. VXLAN bridging/routing with VRF/MLAG support enables cloud-scale overlays. VM Tracer integrates with VMware for visibility into virtual workloads.

What management and monitoring features are included?

CloudVision for ZTP and orchestration; sFlow, IEEE 1588 PTP, optional SSD for logging. LANZ for microburst detection, TAP aggregation, and advanced event monitoring provide deep visibility into network performance and anomalies.

What airflow and power options are available?

Rear-to-front airflow (R designation) with 2x hot-swappable AC PSUs (C13-C14 cords). Configurable fans/PSUs available; supports DC power in related models. Optimized for standard data center rack cooling.

Is this model compatible with Arista EOS software features?

Runs Arista EOS with full 7280R feature set: 768K MAC/IPv6 routes, 24K ACLs per engine (192K system), DCB, PFC/ETS. Backward-compatible with existing optics/cables; supports CloudVision for multi-domain management.
