Description

The 7280R3A is a fixed-configuration 1RU data centre switch router built for Internet peering, data centre interconnect, WAN edge and spine or leaf roles. This DCS-7280SR3AM-48YC8-FLX-R model adds line-rate TunnelSec encryption, covering MACsec, IPsec and VXLANsec, across its ports.

It provides 48 SFP50 ports running 10G, 25G or 50G, along with up to 6 x 200G QSFP ports for uplinks. Switching throughput is 3.6 Tbps (7.2 Tbps full duplex) at 1.35 billion packets per second, with a 4 GB packet buffer and latency from 3.8 us. Precision timing is supported through PTP and SyncE with an OCXO. This SKU includes the FLX software licence with full routing, MPLS and EVPN/VXLAN, uses rear to front airflow and is fitted with 2 x AC power supplies in a 1+1 arrangement, with 3 hot-swap fans in an N+1 arrangement.

The switch accepts 10G, 25G and 50G SFP optics as well as 40G, 100G and 200G QSFP optics and DACs. It runs Arista EOS, with EOS 4.32.1 as the minimum release.
