What is a fabric extender switch?
A Fabric Extender (FEX for short) is a companion to a Nexus 5000 or Nexus 7000 switch. The FEX, unlike a traditional switch, has no capability to store a forwarding table or run any control plane protocols. It relies on its parent 5000/7000 to perform those functions.
What are fabric extenders used for?
