Description

The 7280R3A is a 1RU fixed data centre switch router from Arista, built for spine and leaf fabrics, internet peering, carrier edge and VPN services, and DCI or WAN links that need line-rate encryption across third-party infrastructure. This 7280SR3AM variant adds TunnelSec, so MACsec, IPsec and VXLANsec encryption is available on every port.

It provides 48 SFP50 ports running at 10G, 25G or 50G, plus uplinks of up to 6 x 200G QSFP or 8 x 100G. Switching throughput is 3.6 Tbps (7.2 Tbps full duplex) with 1.35 Bpps forwarding, latency from 3.8 us and a 4 GB packet buffer with Virtual Output Queues per port. Power comes from two hot-swap AC supplies in a 1+1 arrangement, with three N+1 fans and rear-to-front airflow. Typical draw is 290 W and the maximum is 391 W.

The switch runs Arista EOS 4.32.1 or later and is managed with CloudVision. It supports 10G to 200G pluggable optics and DACs, including 100GBASE-SR4, LR4 and 200GBASE-SR4 modules, with 50G and 25G breakout cables available. PTP and SyncE precision timing are built in.
