FAQs

Q: What deployment scenarios is the DCS-7020R4-48Y-4QC-F best suited for?
A: This switch is designed for data center leaf/spine architectures, service provider aggregation, and high-performance enterprise cores requiring high-density 25GbE connectivity with 100GbE uplinks. It excels in software-defined data center fabrics using EVPN-VXLAN overlays, MPLS networks, and environments demanding deep buffers for lossless forwarding.

Q: Does this model support MACsec or enhanced encryption?
A: The DCS-7020R4-48Y-4QC-F is the standard version without enhanced encryption. For hardware-accelerated MACsec and TunnelSec wire-speed encryption at Layer 2 and Layer 3, select the DCS-7020R4M variant which includes the 'M' designation for enhanced encryption capabilities.

Q: What does the 'F' suffix in the SKU indicate?
A: The 'F' designates front-to-rear airflow, where cool air enters from the port side and exhausts through the fan side. This is the standard airflow direction for hot-aisle/cold-aisle data center rack deployments where cold air is supplied at the front of the rack.

Q: What routing protocols and advanced features are supported?
A: Running Arista EOS, the switch supports comprehensive Layer 2/3 protocols including BGP, OSPF, ISIS, MPLS, Segment Routing, EVPN-VXLAN, PIM multicast, MLAG, ECMP, VPN services, precision timing (PTP), and FlexRoute for internet-scale routing tables up to 2.5M routes. It also includes streaming telemetry and Accelerated sFlow for real-time monitoring.

Q: Can this switch be managed with Arista CloudVision?
A: Yes, the DCS-7020R4-48Y-4QC-F integrates natively with Arista CloudVision for centralized provisioning, network-wide visibility, streaming telemetry, change management, and automation. It also supports Zero Touch Provisioning (ZTP), eAPI, OpenConfig, and traditional CLI/SNMP management.
