This chapter describes how to configure a Cisco Nexus 2000 Series Fabric Extender using a parent Cisco Nexus 7000 Series device and includes the following sections:
This section describes how to configure the Fabric Extender.
You can install and manage the Fabric Extender feature set.
1.
Installing the Fabric Extender Feature Set
2.
Enabling the Fabric Extender Feature Set
3.
(Optional) Disallowing the Fabric Extender Feature Set
Step 1 | Installing the Fabric Extender Feature Set |
Step 2 | Enabling the Fabric Extender Feature Set |
Step 3 | (Optional)Disallowing the Fabric Extender Feature Set |
![]() Note | You must enable the Fabric Extender feature set in the default virtual device context (VDC). Once enabled in the default VDC, the FEX can belong to any VDC and can be configured from those VDCs. A single Fabric Extender belongs exclusively to a single VDC. |
Ensure that you are in the default VDC.
Ensure that you have disabled the Intrusion Detection System (IDS) reserved addresses check (it is disabled by default). Use the show hardware ip verify command and look for the string "address reserved" in the output. If the IDS reserved addresses check is enabled, disable it with the no hardware ip verify address reserved command.
1.
configure terminal
2.
install feature-set fex
3.
exit
You can enable the installed Fabric Extender feature set in any VDC on the device.
Ensure that you have installed the Fabric Extender feature set in the default VDC.
Ensure that you are in the correct VDC or use the switchto vdc command.
1.
configure terminal
2.
feature-set fex
3.
exit
By default, when you install the Fabric Extender feature set, it is allowed in all VDCs. You can disallow the installed Fabric Extender feature set in a specific VDC on the device.
Ensure that you have installed the feature set in the default VDC.
Ensure that you have not enabled the feature set in the specified VDC.
1.

end
Command or Action | Purpose | |
---|---|---|
Step 1 | configure terminal Example: switch# configure terminal switch(config)# | Enters global configuration mode. |
Step 2 | vdc vdc_ID Example: switch(config)# vdc 1 | Specifies a VDC and enters VDC configuration mode. |
Step 3 |
no allow feature-set fex Example: switch(config-vdc)# no allow feature-set fex |
Disallows the feature set in the VDC. You cannot disallow a feature set that is enabled in the specified VDC. By default, the installed Fabric Extender feature set is allowed in all VDCs on the device. You can disallow a feature set in a specific VDC. Subsequently, you can change the status back to allowed with the allow feature-set fex command. |
Step 4 | end Example: switch(config-vdc)# end switch# | Exits VDC configuration mode and returns to EXEC mode. |
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.
![]() Note | 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. |
![]() Note | Associating a Fabric Extender to a fabric interface enables the specified port to operate only in shared rate-mode. The port does not support dedicated rate-mode when associated with a Fabric Extender. |
Ensure that you have installed and enabled the Fabric Extender feature set.
