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

Q: What is the difference between the -F and -R airflow models?
A: The DCS-7020TR-48-F features front-to-rear airflow, meaning cool air is drawn in from the front (port side) and exhausted at the rear (PSU side), ideal for cold aisle data center deployments. The -R model has the opposite rear-to-front airflow pattern.

Q: What licensing is required for advanced routing features?
A: The 7020TR-48 supports various license tiers including FLX-Lite and FLX licenses for enhanced Layer 3 routing (OSPF, BGP, IS-IS, PIM), EVPN, and VXLAN. Enhanced and virtualization licenses unlock additional features like VMTracer, automation, and extended routing table capacity up to 200K routes.

Q: Can this switch be used for campus or enterprise edge deployments?
A: Yes, while optimized for data centers, the DCS-7020TR-48-F's 48 Gigabit Ethernet ports and 10G uplinks make it suitable for high-density campus aggregation or distribution layer deployments requiring advanced Layer 3 capabilities and automation.

Q: What makes the packet buffer unique on this switch?
A: The 7020R Series features an ultra-deep 3GB packet buffer with virtual output queues per port, which eliminates head-of-line blocking and efficiently handles traffic spikes and microbursts common in data center environments, ensuring consistent low-latency performance.

Q: Is this switch compatible with multi-vendor environments?
A: Yes, the DCS-7020TR-48-F supports industry-standard protocols including IEEE 802.1Q VLANs, STP/RSTP/MSTP, LACP, LLDP, and open standards-based routing protocols, ensuring seamless integration with multi-vendor network infrastructures.
