Description

The Arista 7280R3A is a 2RU fixed data centre and service provider switch router built for large-scale layer 2/3 cloud and enterprise data centres, carrier edge and core networks, secure internet peering, and encrypted data centre interconnect. It runs Arista EOS and offers line-rate MACsec, IPsec and VXLANsec encryption (TunnelSec) on every port.

This model provides 72 QSFP100 ports for 100GbE, with breakout to 50G, 25G and 10G, and 40G when using QSFP+ optics. Switching capacity is 7.2 Tbps (14.4 Tbps full duplex) at 2.7 Bpps, with 8 GB of packet buffer and latency from 3.8 us. The SKU is the FLX licence bundle with front-to-rear airflow and two hot-swap AC power supplies in a 1+1 arrangement, backed by four N+1 hot-swap fans. FLX covers full routing up to 2M routes, EVPN, VXLAN, segment routing and advanced MPLS with traffic engineering.

The QSFP100 ports accept 100GBASE-SR4, XSR4, SWDM4, SRBD, LR and LR4 optics as well as DAC and AOC cables. Compatible power supplies are PWR-1513-AC and PWR-1512-AC, and the fan tray is FAN-7012H. The switch requires EOS 4.31.2 or later and is managed with CloudVision.
