FAQs

Q: What makes the DCS-7170-32C-M-F different from the standard 7170-32C models?
A: The M-F variant includes expanded memory and an integrated SSD for enhanced performance in advanced applications such as telemetry, deep buffer requirements, and custom P4 programming. It also features front-to-rear airflow optimized for hot aisle/cold aisle data center deployments.

Q: What is P4 programmability and how does it benefit my network?
A: P4 is an open-source programming language that allows you to customize the switch data plane without hardware changes. The 7170 Series supports multiple forwarding profiles that enable advanced use cases like hypervisor offload, network address translation, load balancing, custom encapsulation, and in-network telemetry, traditionally requiring dedicated appliances.

Q: Can this switch support both spine and leaf roles in a data center fabric?
A: Yes, the DCS-7170-32C-M-F is designed for flexible deployment as either a spine or leaf switch in two-tier data center architectures. It supports 128-way ECMP and 64-way MLAG for scalable designs, VXLAN routing and bridging, and customizable forwarding profiles tailored to each role.

Q: What licenses are required for Layer 3 routing on the 7170 Series?
A: The 7170 Series uses Arista's Group 2 fixed platform licensing structure. Enhanced L3 features such as BGP, OSPF, IS-IS, PIM, and NAT require the LIC-FIX-2-E license. VXLAN and VMTracer require the LIC-FIX-2-V license. RIPv2 is supported without additional licensing.

Q: Is the DCS-7170-32C-M-F compatible with existing Arista management tools?
A: Yes, the switch runs Arista EOS and integrates seamlessly with CloudVision for centralized management, telemetry, and automation. It supports Zero Touch Provisioning (ZTP), SNMP, REST APIs, CLI, and streaming telemetry for comprehensive visibility and control across your network.
