Step 4
Associating a Fabric Extender to a Fabric Interface
A FEX is connected to its parent device through a port channel. By default, the parent device does not allow
the attached Fabric Extender to connect until it has been assigned a FEX-number and is associated with the
connected interface.
You must have installed and enabled the Fabric Extender features with the install feature-set fex and
feature-set fex commands before you can configure and use a Fabric Extender that is connected to the
parent switch.
