Arista DCS-7280CR3AM-32S-R | 7280R3A 32-Port 100G Switch, 2x 400G, TunnelSec

Q: What is TunnelSec and why is it important?
A: TunnelSec is Arista's advanced encryption technology providing line-rate AES-256-GCM strong encryption for layer 2 and layer 3 traffic. It supports MACsec, IPsec, and VXLANsec protocols, enabling secure data center interconnects and WAN deployments without performance penalty from 10G to 400G speeds.

Q: Can this switch support both 100G and 400G connectivity simultaneously?
A: Yes, the DCS-7280CR3AM-32S-R provides 32 ports of 100 Gigabit Ethernet via QSFP and 2 ports of 400 Gigabit Ethernet via QSFP-DD, enabling flexible network designs with mixed speed tiers for leaf-spine architectures or data center interconnect applications.

Q: Does this model require a license for TunnelSec encryption?
A: Yes, TunnelSec encryption is an EOS licensed feature. An Enhanced Security Encryption License is required to enable encryption capabilities. Contact XS Network Tech for licensing information specific to your deployment requirements.

Q: What deployment scenarios is this switch optimized for?
A: This switch is ideal for cloud data center leaf and spine networks, IP storage with deep buffers for burst absorption, secure data center interconnect with TunnelSec encryption, high-performance compute environments, and EVPN-VXLAN overlay networks requiring 100G and 400G connectivity.

Q: Is this switch compatible with Arista CloudVision management?
A: Yes, the DCS-7280CR3AM-32S-R runs Arista EOS and fully supports CloudVision for network-wide automation, streaming telemetry, analytics, and zero-touch provisioning, enabling centralized management and monitoring across multi-vendor environments.
