Core Features & Differentiators
Ultra-High-Density Fabric
- 400 GE Access: RG-S6980-64QC delivers 64 QSFP-DD ports for 400 GbE connectivity at line rate.
- 200 GE Access: RG-S6980-128DC offers 128 QSFP56 ports, each supporting 200 GbE or split into 2×100 GbE for versatile deployment.
Non-Blocking Throughput
- 51.2 Tbps switching fabric and 10,300 Mpps forwarding ensure zero oversubscription, handling any mix of elephant and mice flows seamlessly.
Enterprise-Grade Resilience
- Redundant PSUs/Fans: 2+2 power modules and 7+1 fan redundancy keep services alive during maintenance.
- VSU Clustering: Unifies up to eight chassis into one logical switch with <200 ms failover for control and data planes.
Advanced Layer 2/3 & Overlay
- Full support for VLANs, STP/RSTP/MSTP, ERPS; dynamic routing (OSPF v2/v3, BGP, IS-IS, RIP); VRRP; and VXLAN/EVPN overlays for multi-tenant fabrics.
Zero-Loss Ethernet
- PFC and ECN technologies, along with deep buffers, guarantee lossless transport—critical for RDMA, storage, and AI workloads.
AI-FABRIC Load Balancing
- AI-Fabric Tech: RALB and AILB algorithms dynamically optimize traffic distribution, minimizing hotspots during AI model training.
Deployment Scenarios
