This document describes how to configure Virtual Machine Fabric Extender (VM−FEX) with the use of a
method to extend the network fabric down to the Virtual Machines (VMs).

There are no specific requirements for this document.

The information in this document is based on these software and hardware versions:

PALO or Vasona Virtual Interface Card (VIC) (M81KR/M82KR, 1280, P81E if integrated with
Unified Computing System Manager (UCSM))

• 

2 Fabric Interconnects (FIs), 6100 or 6200 Series

• 

vCenter server

• 

The information in this document was created from the devices in a specific lab environment. All of the
devices used in this document started with a cleared (default) configuration. If your network is live, make sure
that you understand the potential impact of any command.

What is VM−FEX? VM−FEX (previously known as VN−link) is a method to extend the network fabric
completely down to the VMs. With VM−FEX, the Fabric Interconnects handle switching for the ESXi host's
VMs. UCSM utilizes the vCenter dVS Application Programming Interfaces (API) to this end. Therefore,
VM−FEX shows as a dVS in the ESXi host.
