What are Fex ports?

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 is a Cisco FEX used for?

Cisco FEX acts as a remote I/O module or virtual line card of Nexus 5K/7K, while offering an agile connectivity for rack and blade servers and for converged fabric deployments. It delivers innovation to the data center, reduces total cost of ownership and gains architectural flexibility.

What is Fex in Cisco UCS?

The Fabric Extender (also referred to as the I/O Module, IOM, or FEX) logically extends the fabric interconnects to the blade server. The best analogy is to think of it as a remote line card that’s embedded into the blade server chassis, allowing blade connectivity to the external world.
