Description

The 7280R3 is a 1RU fixed data centre switch router with wire-speed AES-256-GCM encryption, covering MACsec plus IPsec and VXLANsec through Arista TunnelSec. It is built for secure data centre interconnect, leaf/spine and DCI roles, large-scale layer 2 and layer 3 cloud designs, and internet peering or carrier edge VPN and EVPN services where deep buffers and large routing tables matter.

This SKU is the FLX version, supporting over 256K routes with MPLS and VXLAN. It provides 32 x 100G QSFP100 ports and 4 x 400G QSFP-DD ports, with 4.8 Tbps throughput (9.6 Tbps full duplex), 2 Bpps forwarding, 8 GB of packet buffer and latency from 3.8 us. A quad-core x86 CPU, 64 GB system memory and a 120 GB SSD support the control plane. Cooling is front-to-rear airflow, with 2 x hot-swap AC power supplies in a 1+1 arrangement and 3 x hot-swap fans in N+1.

The 100G QSFP ports accept 100G and 40G optics and can break out to 4x10G or 4x25G, while the QSFP-DD ports take 400G and 100G optics. It runs Arista EOS from the Group 3 fixed-switch licence family and is managed with CloudVision.

FAQs

Q: Does the encryption need a separate licence?
A: Yes. Encryption is an EOS licensed feature and needs a licence file, such as LIC-FIX-3-ENCR for TunnelSec and MACsec on this model family. This SKU uses the Group 3 licence family and carries the FLX routing scale of over 256K routes with MPLS and VXLAN.

Q: What power supplies does it use?
A: It uses 2 x hot-swap PWR-1011 AC power supplies in a 1+1 redundant arrangement. The PWR-1011AC is rated 100-240V AC, 50/60Hz, with 1100 W output and an IEC 60320 C14 inlet.

Q: What optics do the 100G and 400G ports accept?
A: The 100G QSFP ports accept 100G and 40G (QSFP+) optics and cables, and can break out to 4x10G or 4x25G. The 4 x QSFP-DD ports support 400G and 100G optics.

Q: How does this SKU differ from the rear-to-front version?
A: This -F SKU has front-to-rear airflow. The -R SKU is the rear-to-front airflow equivalent. This SKU also has the FLX feature set, with over 256K routes, MPLS and VXLAN.

Q: Which EOS release does it need?
A: It needs a minimum of EOS 4.27.2F and belongs to the Group 3 fixed-switch feature licence family.
