Arista DCS-7280CR3K-96-F | 7280R3 96-Port 100G Switch Router, 9.6Tbps, 16GB Buffer

Q: What makes the K-variant different from the standard 7280CR3-96?
A: The K-variant features expanded FlexRoute capacity supporting over 5 million IPv4 and IPv6 routes, compared to approximately 2 million routes in the non-K variant. This makes it ideal for internet peering, service provider networks, and large-scale data centers requiring full internet routing table support.

Q: Can the 100G QSFP28 ports be broken out to lower speeds?
A: Yes, the QSFP28 ports support flexible breakout configurations to 50G, 40G, 25G, and 10G speeds, allowing up to 192 x 50G interfaces. This provides deployment flexibility for connecting servers, storage, and network devices at various speeds.

Q: What routing protocols and features does this switch support?
A: The DCS-7280CR3K-96-F supports full Layer 3 routing including BGP, OSPF, IS-IS, MPLS (LDP, RSVP-TE, BGP LU), Segment Routing with Traffic Engineering (SR-TE), EVPN, VXLAN, VRF, BFD, and BGP FlowSpec. It provides carrier-grade features for data center interconnect, cloud networking, and service provider applications.

Q: What is the benefit of the 16GB deep packet buffer?
A: The 16GB VOQ deep packet buffer architecture eliminates head-of-line blocking and provides exceptional burst absorption capacity. This is critical for handling TCP incast events, traffic microbursts, and congestion in high-throughput data center spine deployments without packet loss.

Q: Is this switch compatible with Arista CloudVision?
A: Yes, the switch fully integrates with Arista CloudVision for centralized configuration management, network-wide telemetry, topology visualization, and automated provisioning. It also supports Zero-Touch Provisioning (ZTP), streaming telemetry via gNMI, and programmable automation through Python and Bash scripting on EOS.
