Arista DCS-7280DR3AM-36-F | 7280R3A 36-Port 400G Switch, 14.4 Tbps, Enhanced MACsec

Q: What encryption capabilities does the DCS-7280DR3AM-36-F provide?
A: The switch features Enhanced MACsec with wire-speed AES-256-GCM encryption on all 36 ports. It also supports Arista TunnelSec technology for IPsec and VXLANsec, enabling encrypted tunnels across layer 2, layer 3, and overlay networks at line rate.

Q: Can this switch support multiple port speeds simultaneously?
A: Yes, the QSFP-DD ports are backward compatible and can support 400G, 200G, 100G, 50G, and 40G optics simultaneously. The switch can support up to 144 ports at 100G or 232 ports at 25/10G using breakout cables, providing exceptional deployment flexibility.

Q: What are the primary use cases for this switch?
A: The DCS-7280DR3AM-36-F is ideal for data center spine and leaf deployments, high-bandwidth cloud interconnects, content delivery networks, IP storage networks requiring deep buffers, service provider peering applications, and secure data center interconnect (DCI) requiring line-rate encryption.

Q: Does this model support large routing tables for internet peering?
A: The DR3AM model provides standard routing scale suitable for most data center applications. For internet peering or carrier-grade applications requiring over 256K routes, the DCS-7280DR3AK-36-F variant with FlexRoute and enhanced routing scale would be more appropriate.

Q: What software features are included with Arista EOS?
A: Arista EOS provides comprehensive Layer 2/3 features including MLAG, VXLAN, EVPN, BGP, OSPF, IS-IS, MPLS (LDP, RSVP-TE, SR), advanced telemetry with sFlow and INT, CloudVision integration for automation, Zero-Touch Provisioning, and extensive programmability via Python and REST APIs.
