Scaling across a multitude of 1-Gigabit Ethernet, 10-Gigabit Ethernet, unified fabric, rack, and blade
server environments, the Fabric Extender is designed to simplify data center architecture and operations.
The Fabric Extender integrates with its parent switch, allowing zero-touch provisioning as well as
automatic configuration. This integration allows large numbers of servers and hosts to be supported
using the same feature set as the parent Nexus 5000 Series switch, including security and quality of
service (QoS) configuration parameters, with a single point of management as shown in Figure 1-1.
Spanning Tree Protocol (STP) is not required between the Fabric Extender and its parent switch, because
the Fabric Extender an its parent switch allow you to enable a large multi-path, loop-free, active-active
topology.
Since the Fabric Extender is designed to connect to servers directly, by default, all Fabric Extender host
ports are edge ports. In addition, BPDU guard and BPDU filters are also enabled on Fabric Extender
host ports by default.
