Description

The Arista 7280R3 is a 1RU fixed data centre switch router from the 7280R3K family, built for high-density 100G and 400G aggregation, leaf and spine fabrics, Internet peering, carrier edge VPN services and AI/ML cluster networks. It runs Arista EOS and is suited to operators who need deep buffers and large routing tables in a compact chassis.

This model provides 32 x 100G QSFP100 ports and 4 x 400G QSFP-DD ports, delivering 4.8 Tbps of throughput (9.6 Tbps full duplex) and a 2 Bpps forwarding rate, with latency from 3.8 us. It carries an 8GB packet buffer and the large-route (R3K) table scale, supporting over 5M IPv4 routes. This SKU is the FLX licence variant with front-to-rear airflow and two hot-swap AC power supplies in a 1+1 arrangement. FLX covers the Group 3 fixed class feature set, including full routing, EVPN, VXLAN, Segment Routing and advanced MPLS with traffic engineering.

The 400G QSFP-DD ports accept 400G optics and cables and break out to 200G, 100G, 50G or 25G, while the QSFP100 ports support 100G, 50G, 40G, 25G and 10G optics and cables.
