The only way I see to do this from user space is something like the following: SubnGet PortInfo of local port Set IsDeviceManagementSupport bit in PortInfo.CapabilityMask Change any other PortInfo fields so set will work (LinkState andPortPhysicalState set to no state change, don't think any others need changing) SubnSet PortInfo of local port (make sure set worked) The downside is that if your application crashes you will need to have a cleanup program to unset that bit.
