FAQs

Q: What is AlgoMatch technology and what benefits does it provide?
A: AlgoMatch is Arista's hardware and software innovation that combines general-purpose memory with advanced algorithms to enable flexible and scalable access control, policy-based forwarding, and enhanced network telemetry. It delivers higher scale and performance with lower power consumption compared to traditional TCAM-based solutions, while enabling flow matching for improved visibility and policy enforcement.

Q: What deployment scenarios is the DCS-7280SR2A-48YC6-F best suited for?
A: This switch is ideal for high-performance data center leaf-spine architectures, high-frequency trading platforms requiring ultra-low latency, cloud service provider networks, IP storage deployments, and large-scale virtualized environments. The 25G access ports support server connectivity while the 100G uplinks provide high-bandwidth spine connections.

Q: What advanced Layer 2 and Layer 3 features does this switch support?
A: The switch supports VXLAN gateway and routing, EVPN for overlay networks, MLAG for link redundancy, 128-way ECMP for load balancing, full IPv4/IPv6 routing with up to 768K host routes, scalable internet routing tables, and comprehensive QoS and traffic management features through Arista EOS.

Q: What optics and cables are compatible with this switch?
A: The 25G SFP28 ports support 25GBASE-SR/LR optics, 25G DAC/AOC cables, and backward compatibility with 10GBASE and 1000BASE-SX/LX optics. The 100G QSFP28 ports support 100GBASE-SR4/LR4/CWDM4 optics, 100G DAC cables, 40G QSFP+ modules, and can be configured for 4x 25G or 4x 10G breakout modes for maximum flexibility.

Q: Does this switch require any software licenses?
A: The DCS-7280SR2A-48YC6-F is classified as an Arista Group 2 switch. Basic Layer 2/3 switching and routing features are included, while advanced capabilities such as VXLAN, EVPN, enhanced routing, LANZ telemetry, and automation features may require optional software licenses depending on your deployment requirements.
