Cisco Nexus 7000 Switches Second-Generation Supervisor Modules

The Cisco Nexus 7000 Supervisor Modules are designed to deliver scalable control-plane and management functions for the Cisco Nexus 7000 chassis. The supervisor controls the Layer 2 and 3 services, redundancy capabilities, configuration management, status monitoring, power and environmental management, and more. It provides centralized arbitration to the system fabric for all line cards. The fully distributed forwarding architecture allows the supervisor to support transparent upgrades to I/O and fabric modules with greater forwarding capacity. Two supervisors are required for a fully redundant system, with one supervisor module running as the active device and the other in hot-standby mode, providing exceptional high-availability features in data center-class products.
