Description

The Arista 7280R3A is a 2RU fixed data centre switch router built for large-scale spine and leaf fabrics, Internet peering, carrier edge VPN services and encrypted WAN or DCI links. This 7280CR3AM variant adds TunnelSec encryption hardware on every port, so traffic can be protected at line rate across third-party infrastructure.

It provides 72 QSFP100 ports, supporting up to 72 x 100G, 72 x 40G, or breakout to 102 x 50G and 102 x 25/10G, with up to 116 total interfaces. Throughput is 7.2 Tbps (14.4 Tbps full duplex) at 2.7 Bpps, with latency from 3.8 us and 8 GB of deep packet buffer. TunnelSec supports MACsec, IPsec and VXLANsec using AES-256-GCM. This SKU has two hot-swap AC power supplies in a 1+1 arrangement and front-to-rear airflow, with four N+1 fans. Typical power draw is 406 W and maximum is 754 W, excluding transceivers.

It runs Arista EOS 4.31.2 or later and is managed with CloudVision. Compatible power supplies are PWR-1513-AC, PWR-1512-AC and PWR-1511-DC, and the spare fan tray is FAN-7012H.
