Specifications

Product Overview:

The Arista DCS-7280CR3-32P4-F is a high-performance, low-latency Layer 2/3 switch-router hybrid designed for next-generation data center and enterprise networks. This 7280R3 series model combines 32 ports of 100GbE (QSFP28) and 4 ports of 400GbE (OSFP) to deliver a scalable, ultra-fast switching solution that meets the evolving demands of high-throughput environments.
Built to support complex routing scenarios and intense east-west traffic, it features a switching capacity of 4.8 Tbps, a forwarding rate of 2 billion packets per second (Bpps), and latency as low as 3.8 microseconds. With front-to-back airflow, redundant hot-swappable power and fans, and support for advanced routing tables, the DCS-7280CR3-32P4-F is engineered for reliability and efficiency.

Key Features:

32 x 100G QSFP28 (supports 25/40/50/100G)
4 x 400G OSFP uplinks for future-ready scalability
Switching Capacity: 4.8 Terabits per second
Forwarding Rate: 2 Bpps (billion packets per second)
Latency: Starts from 3.8 microseconds
Advanced Layer 3 Routing Scalability
MAC Table Size: Up to 768,000 entries
IPv4/IPv6 LPM Routes: Up to 1.3M (IPv4) and 440K (IPv6) in L3 mode
IPv4 Host Routes: Up to 224K (Balanced)
Multicast Routes: Up to 448K (Balanced)
VLANs: Supports up to 4096
Front-to-Back airflow for in-rack cooling compatibility
Includes 3 x FAN-7011H-F hot-swappable fan modules

Redundant Power & Hot-Swap Design

2 x PWR-1011-AC-RED AC power supplies (included)
Hot-swappable PSU and fan modules for non-stop operations
