Description

The Arista 7280R3 with encryption is a 1RU fixed-configuration data centre switch router built for leaf, spine, data centre interconnect and internet peering roles. It combines line-rate AES-256-GCM encryption (MACsec, IPsec and VXLANsec via TunnelSec) with large route forwarding tables, so secure site-to-site links need no external encryption appliance.

This -R variant provides 32 x 100G QSFP100 ports and 4 x 400G OSFP ports, with 4.8 Tbps of throughput (9.6 Tbps full duplex), 2 Bpps forwarding and an 8 GB packet buffer. Latency starts from 3.8 us. It is powered by two hot-swap AC supplies in a 1+1 redundant arrangement, with three hot-swap fans and rear-to-front airflow. A quad-core x86 CPU, 64 GB of system memory and a 120 GB SSD support EOS and its automation tooling.

The QSFP100 ports accept 100G and 40G QSFP optics and DACs, with breakout modes to 4x10G or 4x25G. The 400G OSFP ports accept 400G optics and cables and also support 200G and breakout to 100G, 50G and 25G. It runs Arista EOS and requires EOS feature licences from Group 3, with encryption enabled by a licence file.

FAQs

Q: Does this switch need a licence?
A: Yes. It runs Arista EOS and needs EOS feature licences from Group 3. Encryption is a licensed feature enabled by a licence file, such as LIC-FIX-3-ENCR for TunnelSec and MACsec.

Q: Which ports support encryption?
A: TunnelSec encryption (MACsec, IPsec and VXLANsec) runs at line rate on the 32 QSFP100 ports using AES-256-GCM.

Q: What optics work in the 400G OSFP ports?
A: The four OSFP ports accept 400G OSFP optics and cables including CR8, AOC, SR8, DR4, XDR4, FR4, 2FR4, LR4, PLR4 and ZR. They also support 200G and breakout to 100G, 50G and 25G.

Q: What power does it need?
A: It uses two hot-swap PWR-1011 AC supplies in a 1+1 redundant arrangement, each taking 100-240V AC at 50/60Hz and delivering 1100 W. Typical draw is 535 W and maximum is 851 W.

Q: What airflow does this -R model use?
A: This SKU uses rear-to-front airflow with the FAN-7011H fan tray, so the cold aisle must be on the rear (power supply) side of the rack.
