Description

The Arista 7020R4 Series Switch Router delivers 48x10GbE RJ45 ports and 4x100GbE QSFP uplinks in a compact 1RU form factor, purpose-built for data centre leaf, service provider access, and high-performance edge deployments. Powered by Arista's 7th Generation R Series architecture with deep buffer Virtual Output Queueing (VOQ), the DCS-7020R4-48TX-4QC-R eliminates head-of-line blocking for lossless forwarding and scales to over 2.5 million routes via the FlexRoute engine — making it ideal for internet peering, broadcast media, and large-scale campus aggregation. Dual AC power supplies and rear-to-front airflow support hot-aisle/cold-aisle data centre deployments.

Running Arista EOS, this switch router supports MPLS, Segment Routing, EVPN-VXLAN, IPv4/IPv6 VPNs, VPLS, IEEE 1588 PTP, and TunnelSec wire-speed encryption at both Layer 2 and Layer 3. Rich streaming telemetry, Accelerated sFlow, and full CloudVision integration provide real-time visibility and automation-ready operations.

FAQs

Q: What is the DCS-7020R4-48TX-4QC-R designed for?
A: This switch router is purpose-built for data centre leaf, service provider access, internet peering, broadcast media, and research network edge applications. Its deep buffer VOQ architecture and FlexRoute engine make it well suited to environments requiring high route scale and lossless forwarding under bursty traffic conditions.

Q: How many routes can the 7020R4 support?
A: The FlexRouteâ„¢ engine on the 7020R4 scales to over 2.5 million routes, making it capable of handling full internet route tables in service provider and large enterprise peering scenarios.

Q: Does the 7020R4 support EVPN and MPLS?
A: Yes. The DCS-7020R4-48TX-4QC-R supports a comprehensive set of overlay and tunnelling technologies including MPLS, Segment Routing (SR), EVPN-VXLAN, EVPN-VPWS, EVPN Multicast, VPLS, LDP, RSVP, GRE, and IPv4/IPv6 VPNs (6PE/6VPE), all running under Arista EOS.

Q: What does 'rear to front airflow' mean for data centre installation?
A: Rear-to-front airflow (also known as port-side exhaust) means air is drawn in from the rear of the chassis and expelled through the front port-side. This is designed for hot-aisle containment setups where the front of the rack faces a cold aisle — check your rack airflow design before ordering to ensure compatibility.

Q: Does this switch support precision timing protocols?
A: Yes. The 7020R4 supports Synchronous Ethernet and IEEE 1588 Precision Time Protocol (PTP), making it suitable for latency-sensitive environments such as broadcast media, financial trading infrastructure, and visual effects production networks.

Q: Can I purchase the Arista DCS-7020R4-48TX-4QC-R in Australia through IP Trading?
A: Yes. IP Trading (iptrading.com.au) is an Australian B2B IT hardware reseller stocking enterprise-grade Arista networking equipment. Contact our team for pricing, availability, lead times, and pre-sales technical advice tailored to your deployment requirements.
