Description

The Arista 7280R3A is a 2RU fixed switch router for large-scale cloud and enterprise data centres, secure internet peering, carrier edge VPN services and carrier core transport. This DCS-7280DR3AK-54-FLX-F is the large routes and TunnelSec (R3AK) model with front-to-rear airflow and 2 x AC power supplies, bundled with the FLX licence.

It provides 54 x 400G QSFP-DD ports, two of which are OSFP-LS line-system ports, with 21.6 Tbps throughput and 8.1 Bpps forwarding. Breakout supports up to 216 x 100G, 348 x 50G or 348 x 25/10G interfaces. A 24 GB packet buffer, latency from 3.8 us and encryption on all ports (MACsec, IPsec and VXLANsec) suit demanding, secure workloads.

It runs Arista EOS and uses Group 5 fixed-switch feature licences, with the FLX licence providing full routing up to 2M routes, EVPN, VXLAN, Segment Routing and advanced MPLS. Power comes from two hot-swap PWR-3001 AC supplies in a 1+1 arrangement, with a typical draw of 933 W. It accepts 10G to 400G pluggable optics and cables from the QSFP, OSFP and QSFP-DD families and is managed with Arista CloudVision.
