FAQs

Q: What makes the DCS-7170-64C-F programmable?
A: This switch features Intel Tofino-based architecture with a P4 programmable data plane, allowing custom forwarding profiles to be deployed without hardware changes. It supports flexible packet processing for VXLAN, NAT, load balancing, and custom protocols through software-defined profiles compiled into Arista EOS.

Q: Can the 100GbE ports be broken out to lower speeds?
A: Yes, the 64 QSFP28 ports support flexible breakout configurations including up to 256x 10/25GbE, 128x 50GbE, or 64x 40/100GbE, providing deployment flexibility for mixed-speed environments and gradual migration paths.

Q: What deployment roles is this switch designed for?
A: The DCS-7170-64C-F is designed for both leaf and spine roles in two-tier data center networks, as well as centralized services nodes. It supports 128-way ECMP and 64-way MLAG for scalable leaf-spine architectures and cloud-scale deployments.

Q: What are the differences between -F and -R airflow models?
A: The -F suffix indicates front-to-rear airflow, where air is drawn from the front and exhausted at the rear. This is designed for hot-aisle/cold-aisle data center configurations where cold air is supplied at the front of racks.

Q: Does this switch require feature licenses?
A: The base switch runs standard data center profiles on Arista EOS. Advanced P4 programmable profiles and specialist forwarding profiles may require an Enhanced Feature License depending on the specific use case and features needed.
