FEX
The Fabric Extender feature allows you to manage a Cisco Nexus 2000 Series Fabric Extender and its association with the Cisco NX-OS switch that it is attached to. A Fabric Extender is connected to the switch through physical Ethernet interfaces or a Port Channel. By default, the switch does not allow the attached Fabric Extender to connect until it has been assigned a chassis ID and is associated with the connected interface. You can configure a Fabric Extender host interface port as a routed or Layer 3 port. However, no routing protocols can be tied to this routed interface.
Note |
FEX feature is available on LAN devices only. Therefore, you will see FEX on Cisco DCNM Inventory Switches. If a Cisco Nexus Switch is discovered as part of SAN fabric, FEX feature is not available. FEX is also not supported on Cisco Nexus 1000V devices. |
Note |
4x10G breakout for FEX connectivity is not supported on Cisco Nexus 9500 Switches. |
Note |
The Fabric Extender may connect to the switch through several separate physical Ethernet interfaces or at most one port channel interface. |
This section describes how to manage Fabric Extender (FEX) on Cisco Nexus Switches through Cisco DCNM.
You can create and manage FEX from Cisco DCNM Inventory > Switches.

To add single-home FEX from the Cisco DCNM Web UI, perform the following steps:
Before you begin
You can add a Fabric Extender (FEX) to the Cisco Nexus Switches through the Cisco DCNM Web Client. If the FEX is physically connected to the switch, FEX will become online after it is added. If the FEX is not physically connected to the switch, the configuration is deployed to the switch, which in turn enables FEX when connected.
Note |
You can create only single homed FEX through Inventory > Switches > FEX > Add FEX. To create a dual-homed FEX, use the vPC wizard through Configure > Deploy > vPC. |
Ensure that you have successfully discovered LAN devices and configured LAN credentials before you configure FEX.

After you review the configuration summary on the Preview window, on the Edit Configuration screen, click Deploy to deploy the FEX for the switch. |
VDCs
This section describes how to manage Virtual Device Contexts (VDCs) on Cisco Nexus 7000 Switches through Cisco DCNM.
Users with the network administrator (network-admin) role can create Virtual Device Contexts (VDCs). VDC resource templates limit the amount of physical device resources available to the VDC. The Cisco NX-OS software provides a default resource template, or you can create resource templates.
You can create and manage VDCs from Cisco DCNM Inventory > Switches > VDCs. As Cisco DCNM supports DCNM on Cisco Nexus 7000 Series only, click an active Cisco Nexus 7000 Switch. After you create a VDC, you can change the interface allocation, VDC resource limits, and the high availability (HA) policies.
The following table describes the fields that appear on this page.
Field |
Description |
||||
---|---|---|---|---|---|
Add |
Click to add a new VDC. |

Suspend |
Allows you to suspend an active non-default VDC. Save the VDC running configuration to the startup configuration before suspending the VDC. Otherwise, you will lose the changes to the running configuration.
|
||||
Rediscover |
Allows you to resume a non-default VDC from the suspended state. The VDC resumes with the configuration that is saved in the startup configuration. |
||||

You can specify the HA policies for single supervisor module and dual supervisor module configurations when you create the VDC. The HA policy options are as follows: Single supervisor module configuration:
Dual supervisor module configuration:
The default HA policies for a non-default VDC that you create is restart for a single supervisor module configuration and switchover for a dual supervisor module configuration. The default HA policy for the default VDC is reload for a single supervisor module configuration and switchover for a dual supervisor module configuration. |
