Description

The Arista 7280R3 with Encryption (7280CR3MK) is a 1RU fixed data centre switch router built for secure data centre interconnect, large-scale L2 and L3 cloud designs, leaf/spine and EVPN/VXLAN overlay networks, internet peering and carrier edge VPN services. This 32D4A model combines 32 x 100G QSFP ports with 4 x 400G QSFP-DD ports.

It delivers 4.8 Tbps of wire-speed throughput (9.6 Tbps full duplex) at 2 Bpps, with 8GB of packet buffer and latency from 3.8 us. TunnelSec provides line-rate AES-256-GCM encryption (MACsec, IPsec and VXLANsec) on the 100G ports. This SKU is the rear-to-front airflow variant with 2 x AC hot-swap PWR-1011 power supplies (1+1), 3 hot-swap fans (N+1), the FLX feature set (over 256K routes, MPLS and VXLAN), Secure Boot enabled and an eight-core x86 CPU with 64GB of system memory.

The 400G QSFP-DD ports support 400GBASE-SR8, DR4, XDR4, FR4, LR4, PLR4 and ZR, plus AOC and CR8, with breakout to 200G, 100G, 50G and 25G. The 100G QSFP ports accept 100GBASE optics, AOC and DAC, as well as 40G QSFP+ and breakout. It runs Arista EOS (Feature License Group 3, minimum EOS 4.27.2F) and is managed with CloudVision.

FAQs

Q: What licensing does this switch use?
A: It runs Arista EOS under Feature License Group 3. The FLX suffix indicates the FLX feature set (over 256K routes, MPLS and VXLAN) is included with this SKU. Encryption is an EOS licensed feature, so confirm the encryption licence requirement when quoting.

Q: What power supplies does it use?
A: It uses two hot-swap PWR-1011 AC power supplies in a 1+1 redundant arrangement. Each PWR-1011AC accepts 100-240V AC at 50/60Hz and delivers 1100 W. Typical and maximum draw for this model is 545 W and 875 W.

Q: Which optics and cables work with the 400G and 100G ports?
A: The 400G QSFP-DD ports support 400GBASE-SR8, DR4, XDR4, FR4, LR4, PLR4 and ZR, plus AOC and CR8, with breakout to 200G, 100G, 50G and 25G. The 100G QSFP ports support 100GBASE-SR4, LR4, CWDM4, DR, FR, PSM4 and ERL4, AOC and DAC, as well as 40G QSFP+ and 4x10G/25G breakout.

Q: Which airflow direction does this SKU have?
A: The -R suffix denotes rear-to-front airflow. The matching fan tray spare is FAN-7011H-R.

Q: Which ports provide TunnelSec encryption?
A: TunnelSec (MACsec, IPsec and VXLANsec) is available on the 100G QSFP100 ports, at line rate with AES-256-GCM.
