Description

The Arista DCS-7280CR-48-F is a high-performance data center switch designed for large-scale cloud and enterprise networks. It delivers 48x 100GbE QSFP100 ports and 8x 40GbE QSFP+ uplinks with 10.24 Tbps of non-blocking throughput and 5.76 Bpps forwarding capacity. Powered by Arista EOS, this 2RU switch provides advanced Layer 2 and Layer 3 features, deep packet buffers, VXLAN overlay support, and comprehensive automation capabilities for modern data center architectures.

Features

Wire-speed Layer 2 and Layer 3 forwarding with full IPv4 and IPv6 support
- Advanced routing protocols: OSPF, BGP, IS-IS, RIP, PIM multicast
- Up to 128-way Equal-Cost Multi-Path (ECMP) routing for load balancing
- Multi-Chassis Link Aggregation (MLAG) for active-active redundancy
- VXLAN overlay networking with EVPN control plane for data center interconnect
- Virtual Routing and Forwarding (VRF-lite) for network segmentation
- Ultra-deep 32 GB packet buffer with Virtual Output Queues (VOQ) to eliminate head-of-line blocking
- 8 hardware QoS queues per port with traffic prioritization and policing
- Spanning Tree Protocols: STP, RSTP, MSTP, Rapid PVST+
- IEEE 802.3ad LACP link aggregation and port channeling
- MAC security (MACsec) support, DHCP relay/snooping, control plane protection
- Policy-based routing, unicast reverse path forwarding (uRPF), bidirectional forwarding detection (BFD)
- Accelerated sFlow and IPFIX for high-capacity telemetry and monitoring
- Arista CloudVision integration for centralized provisioning and analytics
- Zero Touch Provisioning (ZTP) and automated configuration management
- LANZ (Latency Analyzer) for real-time microburst detection and congestion visibility
- OpenStack Neutron support and OpenFlow programmability
- Hot-swappable redundant power supplies and fan trays for high availability

FAQs

Q: What are the primary use cases for the Arista DCS-7280CR-48-F?
A: This switch is ideal for high-performance data center spine and aggregation roles, cloud provider networks, large-scale VXLAN fabrics, and internet peering applications requiring high-density 100GbE connectivity with deep buffers for handling microbursts and storage traffic.

Q: Does the DCS-7280CR-48-F require any software licenses?
A: Arista switches include base EOS features at no additional cost. Optional FLX licenses enable advanced routing protocols (OSPF, ISIS, BGP, PIM), large routing tables (256K-2M routes), EVPN, VXLAN, and AlgoMatch. Monitoring licenses provide ZTP, LANZ, TapAgg, and OpenFlow functionality.

Q: Can the 100GbE ports support lower speeds like 40G or 25G?
A: Yes, the QSFP100 ports support flexible breakout configurations including 4x 25GbE and 4x 10GbE modes using appropriate breakout cables or optics, providing deployment flexibility for mixed-speed environments.

Q: What routing and network virtualization features are supported?
A: The switch supports comprehensive Layer 3 routing including IPv4/IPv6, OSPF, BGP, IS-IS, RIP, multicast (PIM-SM/DM/SSM, IGMP), up to 128-way ECMP, VRF-lite, VXLAN overlay networking with EVPN, and MLAG for active-active redundancy without stacking cables.

Q: What management and automation capabilities does Arista EOS provide?
A: Arista EOS delivers Zero Touch Provisioning (ZTP), LANZ for microburst detection, CloudVision integration for centralized management, native Linux tools, programmable APIs (REST, gRPC), OpenFlow support, accelerated sFlow/IPFIX, and stateful switchover for in-service software upgrades.
