FAQs

Q: What is AlgoMatch technology and how does it benefit this switch?
A: AlgoMatch is Arista's innovative packet matching technology that combines advanced software algorithms with flexible memory architecture to deliver enhanced ACL scale, policy-based forwarding, and network telemetry capabilities beyond standard merchant silicon. This enables more efficient and scalable access control and traffic management for large-scale data center deployments.

Q: Can the QSFP28 ports be broken out into lower-speed connections?
A: Yes, the 6x 100GbE QSFP28 uplink ports support flexible breakout configurations including 6x 100GbE, 24x 25GbE, 6x 40GbE, or 24x 10GbE, providing deployment flexibility for various network architectures and allowing you to maximize port density based on your connectivity requirements.

Q: What is the difference between front-to-rear and rear-to-front airflow models?
A: The DCS-7280SR2A-48YC6M-F features front-to-rear airflow (air flows from the port side to the fan side), which is ideal for cold-aisle containment deployments. The -R variant has rear-to-front airflow for hot-aisle configurations. Select the model that matches your data center cooling design for optimal thermal management.

Q: Is this switch suitable for spine-leaf data center architectures?
A: Absolutely. With 3.6 Tbps throughput, ultra-low 3.8μs latency, and support for VXLAN, EVPN, ECMP, and MLAG, this switch is ideal for leaf-spine deployments. The high port density and 100G uplinks make it perfect for leaf-layer aggregation or top-of-rack applications requiring high-speed server connectivity and scalable fabric architectures.

Q: What Layer 2 and Layer 3 protocols does this switch support?
A: The switch supports comprehensive Layer 2 features including MLAG, VXLAN/EVPN, LACP, MSTP, and MACsec on all ports. Layer 3 capabilities include BGP, OSPFv2/v3, IS-IS, ECMP (up to 128-way), PIM-SM/SSM, HSRP, and VRRP. It also supports advanced automation via eAPI, NETCONF/YANG, OpenConfig, gNMI, and streaming telemetry through Arista EOS.
