Description

The Arista DCS-7170-32CD-F is a programmable 1RU data center switch featuring 32 QSFP100 ports with 100GbE connectivity and dual pipeline architecture based on Intel Barefoot Tofino. Designed for high-performance spine and leaf deployments, it delivers 6.4 Tbps switching capacity and 2.4 Bpps forwarding with sub-microsecond latency. The front-to-rear airflow configuration includes dual hot-swappable AC power supplies and redundant fans, while the P4-programmable data plane supports advanced telemetry, VXLAN, custom encapsulations, and flexible resource scaling for cloud, enterprise, and service provider networks.

Features

P4 programmable data plane with flexible forwarding profiles
- Intel Barefoot Tofino dual-pipeline architecture with 48 programmable match-action stages
- Wire-speed Layer 2 and Layer 3 switching with programmable resource allocation
- 128-way ECMP and 64-way MLAG for scalable leaf-spine fabrics
- VXLAN bridging, routing, and gateway capabilities
- Dynamic packet buffer allocation with 20MB shared memory across all ports
- AlgoMatch for high-scale ACLs and flow-based policy enforcement
- Advanced telemetry with DANZ, sFlow, and latency monitoring (LANZ)
- Custom hash algorithms for persistent and efficient load balancing
- Support for NAT, tunnel termination, and custom encapsulation at line rate
- Hot-swappable dual AC power supplies and N+1 redundant fan modules
- Comprehensive management via Arista EOS CLI, CloudVision, SNMP, and REST API

FAQs

Q: What is the difference between the 7170-32C and 7170-32CD models?
A: The DCS-7170-32CD features dual programmable pipelines with the same 32 QSFP100 port configuration as the 7170-32C, providing the same capabilities as the larger 7170-64C in a compact 1RU form factor. This dual-pipeline architecture offers enhanced programmability and resource flexibility for complex networking applications.

Q: Can the QSFP100 ports support lower speed connections?
A: Yes, all QSFP100 ports support flexible breakout configurations including native 100G/40G operation, or breakout to 4x25G, 4x10G, 2x50G configurations. This allows deployment as 32x100G, 64x50G, or 128x10/25G interfaces depending on network requirements.

Q: What licensing is required for Layer 3 routing features?
A: The 7170 Series uses Arista's standard fixed switch licensing model. Basic Layer 2 and RIPv2 are included. Advanced Layer 3 protocols like BGP, OSPF, ISIS, PIM, and NAT require the Enhanced L3 License (LIC-FIX-2-E). Additional licenses are available for VXLAN/virtualization, monitoring/automation, and advanced MPLS features.

Q: What are typical use cases for the programmable P4 capabilities?
A: The 7170-32CD's P4-programmable architecture enables advanced data center functions including hypervisor offload, large-scale tunnel termination (VXLAN, GENEVE), IPv4/IPv6 NAT at wire speed, custom telemetry and application monitoring, server load balancing, and flexible packet parsing for new protocols without hardware changes.

Q: Is this switch suitable for spine or leaf deployment?
A: Yes, the DCS-7170-32CD-F is designed for both spine and leaf roles in two-tier data center fabrics. It supports 128-way ECMP and 64-way MLAG for scalable leaf-spine designs, making it ideal for high-density 100G spine interconnects or as a compact leaf switch with flexible breakout options for server connectivity.
