Description

The Arista 7280R3 with MACsec is a 1RU data centre switch router built for leaf, spine and data centre interconnect roles. It also suits internet peering, carrier edge VPN and EVPN services, and secure site-to-site encryption where wire-speed MACsec and TunnelSec are needed.

This SKU provides 32 x 100G QSFP100 ports and 4 x 400G QSFP-DD ports, with 4.8 Tbps of throughput (9.6 Tbps FDX), 2 Bpps forwarding and latency from 3.8 us. It carries 8 GB of packet buffer, an eight-core x86 CPU, 64 GB of system memory and a 120 GB SSD. Airflow is rear-to-front, with two hot-swap AC power supplies in a 1+1 arrangement and three hot-swap fans in N+1. Secure Boot is enabled.

It runs Arista EOS under the Feature License Group 3 (LIC-FIX-3-) scheme, and encryption is a licensed feature that requires a licence file. The 100G ports support 40G, 50G, 25G and 10G with breakouts, while the 400G ports accept 400G and 100G optics. Spares include the FAN-7011H fan tray and PWR-1011 power supply.
