Description

The Arista 7280R3A is a 1RU fixed data centre switch router built for large-scale layer 2/3 cloud and enterprise data centres, service provider networks, internet peering, carrier edge VPN services, EVPN for 5G and metro, and secure DCI or WAN encryption. It runs Arista EOS.

This SKU provides 30 x QSFP100/200 ports and 2 x QSFP200/QSFP-DD ports, supporting up to 2 x 400G, 18 x 200G or 36 x 100G ports depending on breakout, with breakout to 50G, 25G and 10G. Throughput is 3.6 (7.2) Tbps FDX with a 1.35 Bpps forwarding rate and latency from 3.8 us. It carries 4 GB of packet buffer and 64 GB of system memory. The TunnelSec variant adds wire-speed encryption on all ports using MACsec, IPsec and VXLANsec with AES-256-GCM. TunnelSec is an EOS licensed feature that requires a licence file to enable, and the switch uses EOS feature licence Group 3. It ships with rear-to-front airflow and 2 x hot-swap AC power supplies in a 1+1 arrangement.

Ports accept QSFP100 and QSFP200 optics and cables, and the QSFP-DD ports support 400G including ZR and ZR+ optics. The minimum EOS release is 4.32.1.
