Description

The 7280R3A is a 1RU fixed data centre switch router built for cloud, data centre interconnect and service-provider networks. This R3AM model adds wire-speed MACsec, IPsec and VXLANsec encryption (TunnelSec) on all ports, making it suited to secure DCI, site-to-site encryption, internet peering, carrier edge and EVPN-VXLAN leaf/spine designs.

It provides 30 x QSFP100/200 ports and 2 x QSFP200/QSFP-DD ports, supporting up to 2 x 400G, 18 x 200G, 36 x 100G, 56 x 50G or 56 x 25/10G interfaces with breakouts. Throughput is 3.6 Tbps (7.2 Tbps FDX) at 1.35 Bpps, with a 4 GB packet buffer and latency from 3.8 us. The FLX routing licence is bundled with this SKU, which has two hot-swap AC power supplies in a 1+1 configuration and front-to-rear airflow.

The switch runs Arista EOS 4.32.1 or later and is managed with CloudVision. Precision timing is supported through PTP and SyncE with OCXO and PPS/10M/ToD inputs. Typical power draw is 302 W, with a maximum of 481 W excluding transceivers.
