Description

The Arista 7280R3A is a 1RU fixed data-centre switch router built for leaf or spine roles in large-scale layer 2/3 cloud data centres, enterprise data centres and service provider networks. This R3AM model adds line-rate encryption (TunnelSec/MACsec) on every port, which suits secure internet peering, carrier edge VPN services, EVPN for 5G, metro and CIN deployments, and encrypted data centre interconnect.

It provides 30 x QSFP100/200 ports plus 2 x QSFP200/QSFP-DD ports for 400G, with breakout options up to 56 x 25/10G ports. Throughput is 3.6 Tbps (7.2 Tbps full duplex) at 1.35 Bpps, with latency from 3.8 us and a 4 GB packet buffer. An eight-core x86 CPU with 64 GB RAM and a 120 GB SSD runs Arista EOS. This SKU ships with the FLX licence (Group 3), covering full routing up to 2M routes, EVPN, VXLAN, segment routing and advanced MPLS LER/LSR with traffic engineering.

The chassis has two hot-swap AC power supplies in 1+1 redundancy and three N+1 fans with rear-to-front airflow. QSFP-DD ports accept 400G optics and cables including CR8, AOC, SR8, DR4, XDR4, FR4, LR4, PLR4 and ZR.

FAQs

Q: Which licence does this SKU include?
A: It is bundled with the FLX licence (Group 3, LIC-FIX-3-FLX). This covers full routing up to 2M routes, more than 24K ACLs, EVPN, VXLAN, segment routing and advanced MPLS LER/LSR with traffic engineering and link/node protection.

Q: What does the R3AM designation mean?
A: The M in R3AM indicates built-in encryption. This model supports MACsec/TunnelSec at line rate on all ports without an extra encryption module.

Q: What power supplies does it use?
A: It runs on two hot-swap AC supplies in 1+1 redundancy (PWR-1512-AC, 1500 W, 200-240 VAC). The PWR-1511-DC supply is also supported. Typical draw is 302 W and maximum is 481 W, excluding transceivers.

Q: Which optics work in the 400G ports?
A: The QSFP-DD ports support 400G CR8, AOC, SR8, DR4, XDR4, FR4, LR4, PLR4 and ZR, plus 200G, 100G, 50G and 25G breakout cables. The QSFP100 ports support 100GBASE-SR4, XSR4, SWDM4, SRBD, LR and LR4, among others.

Q: What airflow direction does this model have?
A: This SKU has rear-to-front airflow, indicated by the -R suffix. The three fans (FAN-7011H) run in N+1 redundancy.

Q: Which EOS version is required?
A: The switch needs Arista EOS 4.32.1 or later. CloudVision management is optional.
