The Direct Attach feature, which previously was licensed separately as a feature pack, is now available in the Edge license. No additional license is required to use this feature.
The Direct Attach feature, which is based on the IEEE version of VEPA, eliminates the virtual switch layer, simplifying the network and improving performance. Direct Attach enables data center simplification by reducing network tiers from four or five tiers to just two or three tiers, depending on the size of the data center.
