Cisco Part Number: N9K-SUP-B+ is a Cisco Nexus 9500 6-Core/12-Thread Supervisor
The Cisco Nexus 9000 Series Switches operate in two distinct modes: Cisco Application Centric Infrastructure (Cisco ACI™) and Cisco NX-OS. In Cisco ACI mode, these switches offer a comprehensive, fully automated, policy-based architecture designed for the creation and management of data center fabrics. Conversely, in Cisco NX-OS mode, these switches provide the flexibility to leverage foundational layer 2/3 technologies, along with contemporary features like VXLAN. This mode also supports a Border Gateway Protocol‒Ethernet VPN (BGP-EVPN) control plane, Segment routing, Multiprotocol Label Switching (MPLS), and automation facilitated through NX-APIs.
The Cisco Nexus 9000 Series Switches encompass the Nexus 9500 Series modular switches and the Nexus 9200/9300 Series fixed switches.
Switch operations are overseen by a set of redundant supervisor modules employing an active-standby model with state synchronization. These supervisors are designed to accept an external clock and facilitate management through various ports, including two USB ports, a serial port, and a 10/100/1000-Mbps Ethernet port. Compatibility is assured for both Cisco ACI and NX-OS deployments across all supervisor variants. It is essential for redundant supervisors within a chassis to be of the same type for optimal performance.
