This section covers observability into the Spectrum-X Ethernet fabric for RoCE (RDMA over Converged Ethernet) environments, including congestion management and buffer tracking for lossless network operation.
-
Professor-X Dashboard: Correlates switch telemetry with RDMA performance to identify congestion and latency issues in the fabric.
-
Traffic and Congestion: Tracks Global Pause frames, buffer occupancy, and ECN (Explicit Congestion Notification) marking to show where data is queued in the fabric.
-
Multi-Plane Dashboards: Compares P0–P3 fabric planes across traffic, ECN, drops, and queue pressure to isolate whether a network symptom is plane-specific or fabric-wide.
-
BGP Operations: Scores BGP session health and recovery across the fabric, lines up BGP update activity with BGP and link events, and narrows a BGP problem to a pod, role, and peer.
-
Adaptive Routing Congestion: Tells fabric congestion apart from link instability, using adaptive routing activity, buffer occupancy, carrier changes, ECN marking, and drops.
