Configuring the Cisco Nexus 2000 Series Fabric Extender
This section describes how to configure the Fabric Extender.
Information About Cisco Nexus 2000 Series Fabric Extender
FEX in Active-Active Mode
Beginning with Cisco NX-OS Release 7.2(0)D1(1) , a Fabric Extender can support connections to two Cisco Nexus 7000 Series switches in active-active mode using a vPC.
A Fabric Extender in active-active (FEX-AA) mode:
-
Uses a vPC to provide a seamless fail-over and fast convergence when one of the switches fail.
-
Supports traffic across both switches to maintain efficiency.
Configuration Synchronization and FEX-AA
The vPC configuration synchronization feature can be used for FEX-AA. Configuration synchronization allows you to synchronize the configuration between a pair of switches in a network. You use a switch profile to create a configuration file that is applied locally and used to synchronize the configuration to the peer.
Guidelines and Limitations for FEX-AA
The following are guidelines and limitations for FEX-AA:
-
FEX-AA is not supported on vPC+ deployments.
-
Configuring FEX-AA across two VDCs on the same chassis is not supported.
-
FEXs configured in AA mode cannot have host interfaces configured in L3 mode.
-
Straight-Through FEX and Active-Active FEX cannot exist on a same ASIC instance.
-
Both Cisco Nexus 7000 Series switches can configure the FEX.
-
Both Cisco Nexus 7000 Series switches must configure the FEX in the same way so that the fex-id is the same for each.
-
The configuration of host ports and host port-channels behind the FEX in AA mode must be the same on both the Cisco Nexus 7000 switches .
-
The FEX image can be downloaded from either Cisco Nexus 7000 Series switch.
Managing the Fabric Extender Feature Set
You can install and manage the Fabric Extender feature set.

(Optional) Disallowing the Fabric Extender Feature Set
DETAILED STEPS
| 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 |
Installing 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.

DETAILED STEPS
Enabling the Fabric Extender Feature Set
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
DETAILED STEPS
Disallowing the Fabric Extender Feature Set
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.

end
DETAILED STEPS
| 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. |
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.
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 | Nexus 7000 doesn't support static pinning configuration on FEX. |
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. |

Dual-Homing of a Server to a FEX with FabricPath
Note | Cisco Nexus 7000 Series switches do not support dual-homing. |
-
Enable FabricPath on each switch.
-
Configure the interfaces that you want to designate as FabricPath interfaces.
-
Set the STP priority device to 8192 on all FabricPath Layer 2 gateway devices.
-
(Optional) Set the STP domain ID for each of the separate STP domains that are connected to the FabricPath network.
-
(Optional) Configure a FEX switch ID.
To configure FabricPath interfaces, follow these steps:
-
(Optional) Enable FabricPath on each switch.
switch# config terminal switch(config)# feature fabricpath switch(config-lldp)# exit switch(config)#
-
After you enable FabricPath on the switch, configure the specified interface as FabricPath interfaces.
switch(config)# interface ethernet 1/2 switch(config-if)# switchport mode fabricpath switch(config-if)# exit switch(config)#
-
Configure the STP priority for all Rapid PVST+ VLANs as 8192.
switch# config terminal switch(config)# spanning-tree vlan 11-20 priority 8192 switch(config)#
-
Configure the STP priority for all MST instances as 8192.
switch# config terminal switch(config)# spanning-tree mst 1-5 priority 8192 switch(config)#
-
(Optional) Configure the STP domain ID on each FabricPath Layer 2 gateway switch attached to the FabricPath network.
switch# config terminal switch(config)# spanning-tree domain 5 switch(config)
-
(Optional) Configure the FEX switch ID.
Note
See the Cisco Nexus 7000 Series NX-OS Interfaces Configuration Guide for information on configuring FEX.
Note
FEX VPC+ configurations are supported only on F2-Series modules.
If you are setting up an initial FEX VPC+ configuration on an F2-Series module, follow these steps:
-
In the VPC domain configuration mode, enable partial DF mode with the fabricpath multicast load-balance command.
-
If disabled, enable TRILL style mac-address learning with the mac address-table core-port-learning command.
-
In the VPC domain configuration mode, configure the emulated switch ID with the fabricpath switchid switchid# command.
-
On each of the VPC/VPC+ peer link interfaces in interface configuration mode, enter theswitchport mode fabricpath command.
-
On each VPC/VPC+ peer link port channel, enter the VPC peer-link command.
-
Configure the VPC ID with the vpc vpcid command.
If you are changing an existing FEX VPC configuration to a FEX VPC+ configuration on an F2-Series module, follow these steps:
-
In the VPC domain configuration mode, enable partial DF mode with the fabricpath multicast load-balance command.
-
If disabled, enable trill style mac-address learning with the mac address-table core-port-learning command.
-
In the VPC domain configuration mode, configure the emulated switch ID with the fabricpath switchid switchid# command.
