Frequently Asked Questions

What is the difference between DCS-7050CX3-32S-R and DCS-7050CX3-32C-R?

The 32S variant is Layer 2 managed, while the 32C variant supports full Layer 3 routing. Select based on whether you need IP routing capability at this switch tier.

What does the -R suffix indicate?

The -R suffix indicates rear-to-front airflow — air enters from the rear and exits from the front, suitable for hot aisle containment configurations.

The Arista DCS-7050CX3-32S-R delivers 32-port 100GbE QSFP28 Layer 2 switching with rear-to-front airflow and Arista EOS — a high-density 100GbE data center switch for spine and aggregation deployments.
