The Cisco Nexus 2000 series Fabric Extender (FEX) is a highly scalable and flexible server networking solution to provide high-density and low-cost connectivity for server aggregation. The FEX is designed to simplify data center architecture and operations.
The FEX provides a single point of management that supports a large numbers of servers and hosts that can be configured with the same feature set as the parent Cisco Nexus switch, including security and quality of service (QoS) configuration parameters. Spanning Tree Protocol (STP) is not required between the Fabric Extender and its parent switch, because the Fabric Extender and its parent switch allow you to enable a large multi-path, loop-free, active-active topology.
