Arista DCS-7280PR3K-24-F | 7280R3 24-Port 400G Switch, 9.6Tbps, Large Routes

Q: What makes the DCS-7280PR3K-24-F suitable for internet peering?
A: The 'K' variant includes Arista's FlexRoute engine with large route table support, enabling internet-scale routing with over 1.3 million IPv4 routes. This makes it ideal for service provider edge, DCI, and peering applications where full BGP table capacity is required.

Q: Can the 400G OSFP ports be broken out to lower speeds?
A: Yes, each 400G OSFP port supports flexible breakout configurations, allowing the switch to operate as 24x 400G, or up to 96x 100G ports using appropriate breakout cables or transceivers.

Q: What is the difference between the PR3K and PR3 models?
A: The PR3K models feature enhanced routing scale with the FlexRoute engine supporting large internet routing tables, while standard PR3 models have smaller routing tables optimized for data center leaf/spine deployments. Both share the same 24-port 400G hardware platform.

Q: Does this switch support VXLAN and network virtualization?
A: Yes, running Arista EOS, the switch fully supports VXLAN overlay networks, EVPN control plane, network virtualization, MLAG, ECMP, and standards-based routing protocols for modern data center fabrics.

Q: What power and cooling options are available?
A: The -F suffix indicates front-to-rear airflow with dual 1500W AC power supplies (PWR-1511-AC-RED). Alternative models support rear-to-front airflow or DC power options. All PSUs and fans are hot-swappable for redundancy.
