Description

The Arista DCS-7280TR3-40C6-F is a high-performance 1RU data center switch router designed for leaf, spine, and aggregation layer deployments. It combines 40 ports of 10GBASE-T copper connectivity with 6 QSFP28 100G uplinks, delivering 800 Gbps of wire-speed performance and 2GB of deep packet buffering. Running Arista EOS with FlexRoute engine, this front-to-rear airflow model supports full Layer 2 and Layer 3 routing with MPLS, VXLAN, and Internet-scale routing capabilities for modern data center fabrics.

Features

Arista FlexRoute engine for Internet-scale routing with flexible forwarding profiles
- 2GB HBM2 deep buffer for lossless forwarding and burst absorption
- Layer 2 and Layer 3 wire-speed forwarding with non-blocking architecture
- VXLAN/EVPN gateway with IRB for overlay network support
- MPLS and Segment Routing Traffic Engineering (SR-TE)
- BGP, OSPF, IS-IS, RIP, and static routing protocols
- MLAG multi-chassis link aggregation for high availability
- Virtual Output Queue (VOQ) architecture to eliminate head-of-line blocking
- Precision Time Protocol (PTP) IEEE 1588v2 with hardware timestamping
- Accelerated sFlow and IPFIX for line-rate telemetry
- LANZ (Latency Analyzer) for micro-burst detection
- CloudVision integration for centralized management and automation
- Zero-Touch Provisioning (ZTP) for rapid deployment
- Stateful switchover for in-service software upgrades
- Advanced security features including MACsec encryption support

FAQs

Q: What is the primary use case for the DCS-7280TR3-40C6-F?
A: This switch router is designed for high-density data center leaf, spine, and aggregation layer deployments requiring 10GBASE-T server connectivity combined with 100GbE uplinks for modern spine-and-leaf architectures.

Q: What routing capabilities does this model support?
A: The 7280TR3-40C6-F supports Internet-scale routing with Arista FlexRoute engine, providing over 256K IPv4/IPv6 routes, full BGP/OSPF/IS-IS support, MPLS/SR-TE, and VXLAN/EVPN for advanced network virtualization and overlay networks.

Q: What is the significance of the -F suffix in the model number?
A: The -F suffix indicates front-to-rear airflow, which is designed to align with hot aisle/cold aisle data center cooling architectures. The corresponding -R model offers rear-to-front airflow for different cooling requirements.

Q: Can this switch be used in spine-and-leaf topologies?
A: Yes, the DCS-7280TR3-40C6-F is optimized for both leaf and spine roles in modern data center fabrics, with 40 x 10G ports for server connectivity at the leaf layer or 100G uplinks for spine interconnection.

Q: What management and monitoring features are included?
A: The switch includes CloudVision integration, Zero-Touch Provisioning, accelerated sFlow, LANZ latency analysis, DANZ monitoring, PTP timing, SNMP, REST API, and programmable automation via Python scripting on Arista EOS.
