What is the exact port configuration of the DCS-7280SE-72-F?

Features 48 x 1/10GbE SFP+ ports and 6 x 100GbE QSFP28 ports. QSFP28 ports support breakout to 4x25GbE or 4x10GbE, providing flexible connectivity for 10G server access and 100G spine uplinks in leaf/spine topologies with full wire-speed across all configurations.

What performance specifications does this switch deliver?

Provides 5.76 Tbps switching capacity, 2.4 Bpps forwarding rate, and latency under 4 microseconds for L3 64-byte packets. 9GB deep packet buffer with VOQ prevents drops during congestion, supporting 288K MAC and 1.4M IPv4 routes for large-scale routing tables.

Does it support network virtualization protocols?

Yes, fully supports VXLAN with EVPN control plane, enabling L2 extension over L3 fabrics. Includes BGP, OSPF, IS-IS routing with VRF and ECMP load balancing up to 64 paths, ideal for multi-tenant cloud environments and container networking overlays.

What management and monitoring features are available?

Arista EOS provides LANZ for microburst detection, accelerated sFlow, PTP IEEE 1588 timing, DANZ TAP aggregation, and CloudVision integration. Zero Touch Provisioning (ZTP) enables automated deployment across thousands of switches with real-time state streaming.

Is the switch suitable for high-density data centers?

Yes, 2RU design with front-to-back airflow, <4W/port power draw, redundant hot-swap PSUs/fans, and NEBS compliance. Tool-less rails and 0-40°C operation support dense rack deployments in hyperscale environments with hot/cold aisle cooling.

What Layer 2/3 features does it support?

L2: 4K VLANs, LACP, RSTP/MSTP, jumbo frames 9216B, IGMP snooping. L3: Static/OSPFv3/BGP/IS-IS/RIP, IPv4/IPv6 unicast/multicast, 12K-256K multicast routes, up to 36K ACL entries with QoS 8 queues/port and traffic shaping.

Product overview

The Arista DCS-7280SE-72-F is a purpose-built data center switch from the 7280E Series, featuring 48 x 10GbE SFP+ ports supporting 1/10GbE speeds and 6 x 100GbE QSFP28 uplink ports configurable as 4x25GbE or 4x10GbE via breakout cables. It delivers 5.76 Tbps switching capacity and 2.4 Bpps forwarding rate with ultra-low latency under 4 microseconds for 64-byte packets. The 2RU fixed form factor includes front-to-back airflow (-F designation), redundant hot-swappable PSUs and N+1 fans, 9GB deep packet buffer, and NEBS-compliant design for hyperscale environments. Powered by Arista EOS, it provides wire-speed L2/L3 forwarding with VXLAN, EVPN, BGP, OSPF, IS-IS support, up to 288K MAC addresses, 1.4M IPv4 routes, and advanced QoS with 8 priority queues per port. Ideal for leaf/spine architectures, cloud networking, and high-frequency trading requiring real-time telemetry via LANZ, sFlow, and PTP. The high-performance x86 CPU enables resilient control plane with VRF and ECMP load balancing. Optimized power consumption under 4W per 10GbE port supports dense deployments with tool-less rack mounting.
