If you implement Layer 2 segments for elastic virtual switches by using VXLANs, EVS automatically creates VXLAN datalinks on the EVS nodes that hosts VNICs for the elastic virtual switch. These datalinks are known as automatically generated VXLAN datalinks and follow the naming convention evs-vxlansegment-ID, where evs is the entity that created the datalink. For example, the name evs-vxlan200 indicates that 200 is the VXLAN ID and evs is the entity that has created this datalink. You can use the dladm show-vxlan command to display the automatically generated VXLAN datalinks. For more information, see Displaying VXLAN Information.
You cannot use the dladm subcommands on automatically generated VXLAN datalinks to delete or rename the datalink. However, you can temporarily set the datalink properties by using the dladm set-linkprop command and the dladm reset-linkprop command.
