Arista DCS-7500R3K-36CQ-LC | 7500R3 36-Port 100G QSFP Line Card, Large Routes

Q: Which chassis models are compatible with this line card?
A: The DCS-7500R3K-36CQ-LC is compatible with Arista 7500N Series chassis including the 7504N, 7508N, and 7512N models. It requires the corresponding 7500R3 Series fabric modules and supervisor modules to operate.

Q: What is the difference between the 7500R3K and standard 7500R3 line cards?
A: The 7500R3K-36CQ-LC supports large-scale routing with over 5 million IP routes, significantly expanding FlexRoute capabilities compared to the standard 7500R3-36CQ-LC which supports more than 1.4 million routes. Both offer the same 3.6 Tbps throughput and 36 x 100G ports.

Q: Can the 100G ports support lower speed breakout configurations?
A: Yes, the QSFP100 ports support flexible speed configurations including 100G, 50G, 40G, 25G, and 10G using appropriate optics and breakout cables. This allows deployment flexibility based on network requirements.

Q: What advanced routing and network virtualisation features are supported?
A: The line card supports VXLAN, BGP EVPN, MPLS VPNs, Segment Routing, MLAG, ECMP, algorithmic ACLs, and Inband Network Telemetry (INT). It also includes sFlow sampling for comprehensive network visibility and traffic analysis.

Q: Is this line card suitable for spine or leaf deployment in a data centre?
A: This line card is designed for universal spine applications in large-scale data centre and cloud networks. Its high route table capacity and wire-speed performance make it particularly well-suited for spine layer deployments requiring internet-scale routing capabilities.
