Explanation:
At the access layer, the Adapter-FEX requires a FEX-enabled adapter on a server that connects to a
parent device that supports virtualization of interfaces. The Adapter-FEX is supported on the
following platforms:
• The Cisco Unified Computing System (UCS) platform supports Adapter-FEX between UCS servers
and the UCS Fabric Interconnect.
• The Adapter-FEX is supported on the Cisco Nexus 5500 Series platform and on the Cisco Nexus
2200 Fabric Extender that is connected to a Cisco Nexus 5500 Series parent device. This
implementation works on a variety of FEX-capable adapters, including the Cisco UCS P81E virtual
interface card (VIC) adapter for the UCS C-Series platform and third party adapters such as the
Broadcom BCM57712 Convergence Network Interface Card, that implement the virtual network tag
(VNTag) technology.
