Arista DCS-7050CX3M-32S-F | 7050X3 MACsec 32-Port 100G Switch, 6.4Tbps, 2x 10G SFP+

Q: What is MACsec and why is it important for data center deployments?
A: MACsec (IEEE 802.1AE) provides wire-speed Layer 2 encryption to secure data in transit between network devices. The DCS-7050CX3M-32S-F eliminates the need for external encryption appliances while maintaining full throughput and low latency, making it ideal for secure multi-tenant cloud environments, data center interconnects, and compliance-driven deployments.

Q: Can the QSFP28 ports be configured for lower speeds?
A: Yes, each 100GbE QSFP28 port supports flexible breakout configurations including 40GbE, 4x25GbE, 4x10GbE, or 2x50GbE modes. This allows up to 128 ports of 10/25GbE connectivity, enabling seamless migration from legacy 10G/40G infrastructure to 25G/100G networks.

Q: What is the difference between the -F and -R suffix models?
A: The -F suffix indicates front-to-rear airflow (intake from port side, exhaust from rear), while -R models feature rear-to-front airflow. The airflow direction must match your data center's hot-aisle/cold-aisle cooling architecture for optimal thermal management.

Q: Is this switch suitable for leaf or spine deployments?
A: The DCS-7050CX3M-32S-F is versatile for both roles. It excels as a high-density 100G spine switch or as a secure leaf switch for high-performance server and storage connectivity. The MACsec capability is particularly valuable for encrypting inter-rack or inter-datacenter traffic.

Q: Does the switch support VXLAN and modern overlay networking?
A: Yes, running Arista EOS, the switch fully supports VXLAN routing, bridging, and gateway functions, along with EVPN for network virtualization. It also supports advanced Layer 2 and Layer 3 features including BGP, OSPF, multicast, and programmable automation via REST APIs and NetConf.
