Core Product Positioning
The Cisco N9K-SUP2-E Supervisor Module is a high-performance control-plane, route processing and chassis management component designed exclusively for Cisco Nexus 9500 modular aggregation/spine switches. It manages chassis orchestration, environmental monitoring, configuration synchronization and centralized route computation under both NX-OS standalone mode and ACI fabric mode. Optimized for large-scale leaf-spine data center architectures, multi-tenant virtualized workloads, enterprise IP fabrics and hybrid cloud deployments. It supports 1+1 redundant deployment to guarantee high availability and broad compatibility with legacy and cloud-scale fabric modules and I/O line cards for the Nexus 9500 chassis platform.
