Frequently asked questions

What is the switching capacity and forwarding performance of the DCS-7020TRA-48-F?

The 7020TRA-48-F delivers up to 216Gbps throughput with 300Mpps forwarding rate and wire-speed L2/L3 forwarding across all ports simultaneously. The ultra-deep 3GB packet buffer absorbs microbursts, and sub-microsecond latency ensures optimal performance for latency-sensitive applications in data center environments.

What are the port configurations and uplink options?

The switch provides 48x 100/1000Mb RJ45 ports for server connectivity and 6x SFP+ ports supporting both 1G and 10G uplink speeds. This configuration enables flexible deployment with Gigabit Ethernet servers and 10GbE uplinks to spine-layer switches in leaf-spine architectures.

How does AlgoMatch technology differentiate the TRA variant from the standard TR model?

AlgoMatch is Arista's advanced packet matching and processing engine included in the TRA variant. It enables sophisticated traffic classification, policy enforcement, and packet manipulation capabilities beyond standard switching, supporting complex network policies and application-aware networking in cloud and virtualized environments.

What virtualization and cloud platform support does this switch offer?

The 7020TRA-48-F supports VMware vSphere, OpenStack, and Hyper-V with VM Tracer integration for virtual machine tracking. VXLAN support enables network virtualization, while LANZ provides microburst detection and latency analysis for optimized virtual machine traffic patterns.

What monitoring and management capabilities are included?

CloudVision provides centralized management and monitoring across the network. Advanced features include LANZ for microburst detection, DANZ advanced mirroring and TAP aggregation for packet capture, sFlow for traffic analysis, and Zero Touch Provisioning (ZTP) for simplified deployment in large-scale data centers.

What routing protocols and Layer 3 features are supported?

The switch supports OSPF, OSPFv3, BGP, MP-BGP, IS-IS, RIP-2, and static routing. Additional Layer 3 features include VRRP for gateway redundancy, PIM-SM for multicast, IGMP v1/v2/v3 snooping, and MSDP for multicast source discovery in complex enterprise networks.
