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.
After initial deployment, the new fabric shows Uplink Count as ‘zero’ and shows a warning (yellow triangle with 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.
