NOTE: As of OME-M 1.20.00 and OS10.5.0.7, the preferred uplink type is the Ethernet - No Spanning Tree Protocol uplink. The legacy Ethernet uplink is still available but is no longer recommended. The process for creating a legacy Ethernet uplink is the same as below except for selecting Ethernet as the uplink type.
An Ethernet - No Spanning Tree uplink represents a SmartFabric as an end host with multiple adapters to the upstream network. For this, STP is disabled on the uplink interfaces. A loop-free topology without STP is achieved by not allowing overlapping VLANs across uplinks.
NOTE: Ethernet - No Spanning Tree uplink is supported with Dell EMC and non-Dell EMC switches in a vPC/VLT. Each uplink must be a single LACP LAG. Uplinking to a port extender such as a Cisco FEX is not currently supported.
NOTE: To change the port speed or breakout configuration, see Configure uplink port speed or breakout section of the Dell EMC PowerEdge MX Networking Deployment Guide and make the changes before creating the uplinks.
After initial deployment, the new fabric shows Uplink Count as "zero" and shows a warning (yellow triangle with an exclamation point). The lack of a fabric uplink results in a failed health check (red circle with x). To create the uplink, perform the following steps.
Steps
1. Open the OME-M console.
2. From the navigation menu, click Devices > Fabric.
3. Click the fabric name. In this example, SmartFabric is selected.
4. In the Fabric Details pane, click Uplinks.
5. Click the Add Uplinks button.
6. In the Add Uplink window, complete the following:
NOTE: For more information about Uplink Failure Detection, see the Uplink failure detection section of the Dell EMC PowerEdge MX Networking Deployment Guide.

7. Click Finish.
8. SmartFabric creates the uplink object, and the status for the fabric changes to OK (green box with a checkmark).
NOTE: VLAN1 is assigned to Untagged Network by default.
