Description

The Arista 7280R3 Series 7280CR3K is a 2RU fixed data-centre switch router built for Internet peering, cloud and service-provider edge roles, as well as data-centre spine and leaf, inter-DC networking, EVPN for 5G/MEC and metro deployments that need deep buffers and large routing tables.

It provides 96 x QSFP100 ports running at 100G, with breakout to 50G, 40G and 25/10G, giving up to 192 total interfaces. Throughput is 9.6 Tbps (19.2 Tbps FDX) with 4 Bpps packet forwarding, latency from 3.8 us and a 16 GB deep packet buffer. As a large-route (K) model, the FlexRoute engine extends to over 5M IPv4 routes. This SKU ships in a front-to-rear airflow configuration with two AC hot-swap power supplies in a 1+1 arrangement, plus four hot-swap fans.

It runs Arista EOS 4.24.0 or later and falls under EOS Feature License Group 4, with optional licences available for enhanced L3, virtualisation, monitoring and automation features. The 100G QSFP ports accept 100G optics and DACs, as well as 50G, 40G (QSFP+) and 25/10G breakout depending on the transceiver or cable used.
