Arista DCS-7280CR3AK-32S-R | 7280R3A 30-Port 100G Switch, 2x 400G, TunnelSec

Q: What encryption capabilities does the DCS-7280CR3AK-32S-R support?
A: This model features TunnelSec encryption with line-rate AES-256-GCM encryption supporting IEEE 802.1AE MACsec, IPsec (RFC 4303), and VXLANsec across all ports at full wire speed up to 3.6 Tbps.

Q: Can this switch be used for both data center spine and leaf deployments?
A: Yes, the 7280CR3AK-32S-R is ideal for both spine and leaf roles. Its high port density, deep buffers, and large routing table support make it suitable for universal leaf-spine designs, EVPN-VXLAN overlays, and Internet peering applications.

Q: What is the difference between the -R and -F airflow designations?
A: The -R suffix indicates rear-to-front airflow (exhaust toward the port side), which is designed for cold-aisle intake environments. The -F model has front-to-rear airflow (exhaust toward the fan side) for hot-aisle exhaust deployments.

Q: Does this switch support breakout cables for higher port density?
A: Yes, the QSFP100/200 ports support breakout to 25G, 50G, and 100G configurations, allowing up to 56 maximum total interfaces depending on transceiver and cable capabilities. Specific configurations depend on EOS software support.

Q: What routing protocols and scale does the 'K' variant support?
A: The 7280CR3AK-32S-R features Arista's FlexRoute engine with large routing table support, scaling to millions of routes for Internet peering. It supports BGP, OSPF, IS-IS, EVPN, MPLS, VXLAN, segment routing, and advanced IPFIX/sFlow telemetry.
