Description

The Arista 7280R3A is a 1RU fixed data centre switch router built for spine and leaf fabrics, internet peering, carrier edge VPN services and encrypted data centre interconnect links. This 7280CR3AK-32S variant adds large route scale and TunnelSec encryption, and ships with the FLX routing licence.

It provides 30 x QSFP100 ports and 2 x QSFP-DD 400G ports, with breakout support to 200G, 100G, 50G, 25G and 10G for up to 56 interfaces. Throughput is 3.6 Tbps (7.2 Tbps full duplex) and forwarding reaches 1.35 Bpps, with latency from 3.8 us and a 4 GB deep packet buffer. The 7280CR3AK model supports over 5M IPv4 routes, and TunnelSec delivers line-rate MACsec, IPsec and VXLANsec on all ports. The FLX licence covers full routing up to 2M routes, EVPN, VXLAN, segment routing and advanced MPLS.

This SKU has rear-to-front airflow with two hot-swap 1500W AC power supplies in a 1+1 arrangement and three N+1 fans. It runs Arista EOS 4.32.1 or later and is managed through CloudVision or open APIs.
