Why each option
On a Cisco Nexus 7000 Series Switch, the data plane, which is responsible for high-speed packet forwarding and switching, operates primarily on the unified crossbar fabric modules.
The supervisor module on a Nexus 7000 typically handles the control plane (e.g., routing protocols, management) and management plane, not the high-speed data plane operations.
On a Cisco Nexus 7000 Series Switch, the data plane, responsible for forwarding packets and performing switching operations, primarily operates within the unified crossbar fabric modules. These fabric modules provide the high-speed interconnectivity between line cards, enabling wire-speed forwarding for all ports.
Unified port controllers are typically integrated into line cards, managing individual ports and their initial processing, but the central high-speed data forwarding across the switch relies on the fabric.
The Connectivity Management Processor (CMP) is typically used for out-of-band management and initial boot-up processes, not for data plane operations.
