Data Center & AI Fabric

Data Center & AI Fabric documents AsterNOS on CX-N and related data-center switches: leaf–spine underlay, BGP EVPN VxLAN overlay, MC-LAG, ECMP, and lossless Ethernet for AI training (RoCEv2, PFC, ECN, and Easy RoCE).

Operators use a Cisco-like CLI (KLISH) to configure fabrics that scale from small GPU clusters to multi-pod AI backends. The library covers installation, day-one access, feature configuration, REST API automation, and field-proven technical designs.
