Description

The Arista DCS-7280DR3AM-54-F is a high-performance 2RU data center switch router from the 7280R3A Series, delivering 54 ports of 400GbE QSFP-DD connectivity with 21.6Tbps switching capacity. Designed for hyperscale data centers, internet peering, and service provider environments, it features line-rate Enhanced MACsec encryption, ultra-deep packet buffers up to 24GB, and FlexRoute engine for internet-scale routing. This model includes front-to-rear airflow and dual AC power supplies for optimal cooling in hot-aisle/cold-aisle deployments.

Features

Virtual Output Queuing (VOQ) architecture eliminates head-of-line blocking
- FlexRoute engine with flexible forwarding profiles for optimized L2/L3 table allocation
- Accelerated sFlow and IPFIX for wire-speed network telemetry and monitoring
- Inband Network Telemetry (INT) with per-flow latency, jitter, and path tracking
- Line-rate MACsec (IEEE 802.1AE), IPsec (RFC 4303), and VXLANsec encryption
- EVPN-VXLAN overlay networking with MPLS and Segment Routing support
- Advanced Event Management (AEM) for network automation and programmability
- Precision Time Protocol (IEEE 1588 PTP) and SyncE for sub-microsecond timing
- Layer 2 features: MLAG, LACP, STP/RSTP/MSTP, VLANs (4K), VSS, QinQ
- Layer 3 features: BGP, OSPF, IS-IS, BFD, PIM, IGMP, VRF-lite, multicast routing
- Security: Algorithmic ACLs, 802.1X, RADIUS, TACACS+, SSH, SNMPv3
- Zero Touch Provisioning (ZTP) for automated deployment
- Stateful switchover and in-service software upgrades (ISSU) with no downtime
- Hot-swappable, redundant power supplies and fan modules
- NEBS Level 3 certified for carrier-grade reliability
- Open APIs (REST, JSON-RPC, OpenConfig, gRPC) for programmability

FAQs

Q: What is the difference between the DCS-7280DR3AM-54-F and standard R3A models?
A: The 'M' designation indicates Enhanced MACsec (TunnelSec) support, providing line-rate AES-256-GCM encryption for MACsec, IPsec, and VXLANsec at full 21.6Tbps capacity. The '-F' suffix specifies front-to-rear airflow with 2x AC power supplies included. Standard R3A models lack hardware encryption acceleration.

Q: Can this switch support multiple speed breakouts on the 400G ports?
A: Yes, each QSFP-DD port supports flexible breakout configurations including 1x400G, 2x200G, 4x100G, 4x50G, or 8x50G, providing deployment flexibility for mixed-speed environments. Optics and cable compatibility should be verified via Arista's transceiver compatibility matrix.

Q: What are typical use cases for the 7280DR3AM-54-F?
A: This switch is ideal for hyperscale data center spine/leaf architectures, high-frequency trading environments requiring ultra-low latency, internet exchange points (IXPs), content delivery networks (CDNs), encrypted data center interconnect (DCI), and AI/ML workloads with high-bandwidth storage requirements.

Q: Does this model require software licensing for full functionality?
A: Arista EOS comes fully featured on the switch. CloudVision integration for advanced telemetry and automation requires separate subscription licensing. TunnelSec encryption features are hardware-enabled and included with the platform at no additional software cost.

Q: What is the difference between R3A, R3AM, and R3AK model variants?
A: R3A provides standard L2/L3 features and scale; R3AM adds hardware-accelerated encryption (MACsec, IPsec, VXLANsec); R3AK includes both encryption and large-scale routing tables (5M+ routes) with algorithmic ACLs for advanced policy and telemetry applications.
