FAQs

Q: What deployment scenarios is the DCS-7280CR2-60-F best suited for?
A: This switch is ideal for data center spine and core deployments, Internet peering, data center interconnect (DCI), and high-density 100GbE leaf/spine architectures. Its deep buffer and Layer 3 routing capabilities make it well-suited for service provider and large enterprise networks.

Q: Can the 100GbE ports be broken out to lower speeds?
A: Yes, each QSFP100 port supports flexible breakout to 4x25GbE or 4x10GbE, enabling configurations up to 240 x 25GbE or 240 x 10GbE ports. This provides deployment flexibility for mixed-speed environments.

Q: What Layer 3 routing protocols and features does this switch support?
A: The DCS-7280CR2-60-F supports full Layer 3 switch router capabilities including BGP, OSPF, IS-IS, MPLS (LDP, RSVP-TE, BGP LU), Segment Routing (SR-MPLS), EVPN, VXLAN, and 128-way ECMP. It can support full Internet routing tables with 1.3M IPv4 LPM routes.

Q: What is the significance of the 24GB deep packet buffer?
A: The 24GB Virtual Output Queue (VOQ) deep buffer architecture provides substantial burst absorption capacity, handling transient congestion, TCP incast events, and bursty traffic patterns without packet drops. This is critical for high-performance data center applications.

Q: Is this switch compatible with Arista CloudVision management?
A: Yes, the DCS-7280CR2-60-F integrates with Arista CloudVision for centralized network-wide configuration management, change control, topology visualization, and compliance monitoring. It also supports Zero-Touch Provisioning (ZTP) for automated deployment.
