Description

The Arista 7280R3 (7280CR3-32D4) is a 1RU fixed data centre switch router built for large-scale leaf/spine and layer 2/3 cloud designs, overlay networks using EVPN/VXLAN, Internet peering, inter-DC interconnect and carrier edge or metro/5G transport.

It provides 32 x 100G QSFP100 ports and 4 x 400G QSFP-DD ports, with 4.8 Tbps of throughput (9.6 Tbps full duplex), 2 Bpps forwarding and latency from 3.8 us. An 8 GB deep packet buffer with virtual output queues per port helps avoid head-of-line blocking. This is the expanded-memory variant with 64 GB of system memory, bundled with the FLX software licence for full routing up to 2M routes, more than 24K ACLs, EVPN, VXLAN, segment routing and advanced MPLS. Power comes from two hot-swap AC supplies in a 1+1 arrangement, with three N+1 fans and front-to-rear airflow. Typical draw is 535 W, with a maximum of 851 W.

The ports accept QSFP100 optics and cables, 40G QSFP+, 50G and 25/10G via breakout, and QSFP-DD 400G modules. It runs Arista EOS 4.22.1 or later and is managed with CloudVision.
