Description

The Arista 7280R3K is a 1RU fixed data centre switch router built for secure data centre interconnect, leaf and spine fabrics, Internet peering, carrier edge VPN services and EVPN/MPLS metro and 5G transport. It combines deep buffers with built-in wire-speed encryption on the QSFP100 ports.

This DCS-7280CR3MK-32D4S-FLX-R provides 32 x QSFP100 ports and 4 x QSFP-DD 400G uplinks, with breakout support up to 48 x 100G, 96 x 50G or 96 x 25/10G ports. Throughput is 4.8 Tbps (9.6 Tbps FDX) at 2 Bpps, with latency from 3.8 us and 8 GB of packet buffer. It ships with two hot-swap AC power supplies in a 1+1 arrangement and three hot-swap fans, with rear-to-front airflow. The FLX routing licence is part of this SKU, giving full routing with over 256K routes, MPLS and VXLAN. It runs Arista EOS in Feature License Group 3. MACsec and TunnelSec encryption is a licensed EOS feature that needs a licence file.

The 400G QSFP-DD ports support 400G-CR8, AOC, SR8, DR4, XDR4, FR4, LR4, PLR4 and ZR, plus 200G, 100G, 50G and 25G breakout cables. The QSFP100 ports take 100G and 40G optics and cables. The switch is managed with Arista CloudVision and requires EOS 4.25.2F or later.
