Core Product Positioning
The Cisco N9K-SUP-E Supervisor Module is an advanced control-plane and management component designed exclusively for Cisco Nexus 9500 modular spine/aggregation switches. It delivers centralized chassis orchestration, configuration management, environmental monitoring, and route processing under NX-OS or ACI operational modes. Built for leaf-spine data center architectures, cloud computing, virtualized workloads and enterprise IP fabric deployments, it supports 1+1 redundant deployment to maximize system uptime. It provides broad compatibility with classic and cloud-scale fabric modules and I/O line cards for the Nexus 9500 chassis platform.
2. Hardware Compatibility
Supported Chassis
N9K-C9504, N9K-C9508, N9K-C9516
