Description

The Arista 7280R3K is a 1RU fixed data centre switch router in the 7280R3 series, built for leaf, universal spine and cloud-grade routing or peering roles that need deep buffers and large route scale. It also suits service-provider edge, WAN and DCI aggregation with MPLS and Segment Routing.

It provides 32 x 100GbE QSFP100 ports and 4 x 400GbE OSFP ports, with 4.8 Tbps of wire-speed forwarding (9.6 Tbps full duplex) and 2 Bpps packet forwarding. Latency starts from 3.8 us, with an 8 GB packet buffer and 64 GB of system memory. This SKU is the large-routes 7280R3K variant with rear-to-front airflow, 2 x hot-swap AC power supplies in a 1+1 arrangement and the FLX routing licence bundle. It runs Arista EOS with Group 3 feature licensing.

The OSFP ports accept 400G optics and cables and support breakout to 4 x 100G and 2 x 200G. The QSFP100 ports support 100G and 40G, with breakout to 50G, 25G and 10G where the optic supports it. Minimum EOS is 4.27.2.
