Arista DCS-7020TR-48-R | 7020R 48-Port Gigabit Switch, 6x 10G SFP+

Q: What is the difference between the DCS-7020TR-48-R and DCS-7020TR-48-F models?
A: The R model features rear-to-front airflow (port side exhaust), ideal for cold-aisle deployments where cable entry is at the front. The F model has front-to-rear airflow for hot-aisle configurations. Both have identical port configurations and performance.

Q: Does the DCS-7020TR-48-R support advanced Layer 3 routing and VXLAN?
A: Yes, with appropriate licensing the 7020TR-48 supports comprehensive Layer 3 routing protocols including BGP, OSPF, ISIS, and PIM, as well as VXLAN gateway, bridging, and routing for software-defined data center deployments.

Q: What makes the 3GB packet buffer important for data center applications?
A: The deep 3GB buffer with Virtual Output Queuing eliminates head-of-line blocking and absorbs traffic bursts common in server-to-server communication, ensuring consistent low latency and preventing packet loss during congestion events in high-density environments.

Q: Can this switch be used in a leaf-spine architecture?
A: Absolutely. The 7020TR-48-R is designed for scalable two-tier leaf-spine designs, offering 48 server-facing Gigabit ports and 6x 10G uplinks for spine connectivity, with support for 128-way ECMP and 64-port MLAG for redundancy and load balancing.

Q: What software features are available on Arista EOS for this switch?
A: Arista EOS provides Zero Touch Provisioning, VMTracer for VM visibility, integrated packet capture, sFlow, advanced event management, CloudVision integration, REST APIs for automation, and comprehensive network telemetry for monitoring and capacity planning.
