Description

The Arista 7280R3 (7280R3K with encryption) is a 1RU fixed data-centre and DCI switch router built for secure data centre interconnect, large-scale L2/L3 cloud designs, leaf/spine roles, overlay networks, internet peering and carrier edge VPN/EVPN services.

It provides 32 x 100GbE QSFP100 ports and 4 x 400GbE OSFP ports, with 4.8 Tbps of wire-speed forwarding (9.6 Tbps full duplex), 2 Bpps and an 8 GB packet buffer. Latency starts from 3.8 us. This SKU carries the FLX licence tier for full routing with over 256K routes, MPLS and VXLAN, and uses front-to-rear airflow. It is fitted with 2 x hot-swap AC power supplies in a 1+1 arrangement and 3 x hot-swap fans, with a typical draw of 535 W and a maximum of 851 W. TunnelSec on the QSFP100 ports delivers wire-speed AES-256-GCM encryption across MACsec, IPsec and VXLANsec.

The OSFP ports accept 400G, 200G and 100G optics and cables, while the QSFP ports support 100G and 40G optics with breakout to 4x10G or 25G. The switch runs Arista EOS and needs EOS 4.25.2F or later.

A: This -FLX SKU includes the FLX licence tier under the Group 3 Fixed feature licence, covering full routing with over 256K routes, EVPN, VXLAN, Segment Routing and MPLS.

Q: Does it support encryption?
A: Yes. The QSFP100 ports are TunnelSec capable with wire-speed AES-256-GCM encryption for MACsec, IPsec and VXLANsec. Encryption is an EOS licensed feature enabled with the LIC-FIX-3-MACSEC or LIC-FIX-3-ENCR licences.

Q: What power supplies does it use?
A: It uses two hot-swap PWR-1011 AC supplies in a 1+1 redundant arrangement, rated for 100-240V AC with 1100 W output and 93% Platinum efficiency.

Q: Which optics do the 400G OSFP ports accept?
A: They accept 400GBASE-CR8, AOC, SR8, DR4, XDR4, FR4, 2FR4, LR4, PLR4 and ZR optics, and can break out to 200G, 100G, 50G and 25G cables.

Q: How does the -F suffix differ from other variants?
A: The -F suffix denotes front-to-rear airflow. Rear-to-front airflow is available on the -R SKUs.
