Description

The Arista 7280R3 is a 1RU fixed-configuration routing switch built for data centre interconnect, leaf and spine roles in large cloud data centres, internet peering and carrier edge VPN services. It supports EVPN/VXLAN overlays and MPLS or SR-TE cores, with wire-speed encryption for links between tiers or sites.

The DCS-7280CR3MK-32D4A-S-FLX-F provides 32 QSFP100 ports plus 4 QSFP-DD ports for 400G uplinks, with 4.8 Tbps (9.6 Tbps FDX) throughput, 2 Bpps forwarding and latency from 3.8 us. It has 8 GB of packet buffer, an eight-core x86 CPU, 64 GB of system memory and a 120 GB SSD. This SKU has front-to-rear airflow, dual hot-swap AC power supplies in 1+1 redundancy, three N+1 hot-swap fans and Secure Boot enabled. The FLX software licence covers large-scale routing with over 256K routes, MPLS and VXLAN. MACsec and TunnelSec encryption is available on the QSFP100 ports.

The QSFP-DD ports accept 400GBASE optics and DAC/AOC options with 200G, 100G, 50G and 25G breakout. The QSFP100 ports support 100GBASE optics with 40G, 25G and 10G breakout. The switch runs Arista EOS 4.27.2F or later and is managed with CloudVision.
