Description

The Arista 7280R3A is a 2RU fixed data centre switch router built for leaf, spine, Internet peering and data centre interconnect roles that need Internet-scale routing. It runs Arista EOS and combines a deep 8 GB packet buffer with the FlexRoute engine for hardware routing at scale.

This DCS-7280CR3A-48D6-FLX-R model provides 48 x 100G QSFP100 ports and 6 x 400G QSFP-DD ports, plus one OSFP-LS port for 400G-ZR. It delivers 7.2 Tbps of throughput (14.4 Tbps full duplex) and 2.7 Bpps forwarding, with latency from 3.8 us. This SKU carries the FLX licence for full routing, EVPN, VXLAN, Segment Routing and advanced MPLS, uses rear-to-front airflow and has two hot-swap AC power supplies in a 1+1 arrangement.

The 100G ports accept 100G optics and support 40G QSFP+ and breakout to 50G, 25G and 10G, while the QSFP-DD ports take 400G modules and 100G or 200G breakouts. Precision timing is supported through PTP and SyncE. Minimum EOS release is 4.31.1.
