Dear Qianjiang,

*system host-lock ${COMPUTE}

#If the interface has been bound to other datanetwork, need to remove
the binding.
system interface-datanetwork-list ${COMPUTE}
system interface-datanetwork-remove ${PHYSNETDATA0UUID}*

#Create a flat datanetwork and bind it to the interface.
system datanetwork-add phy-flat flat
system host-if-modify -m 1500 -n data0 -c data ${COMPUTE} ${DATA0IFUUID}
system interface-datanetwork-assign ${COMPUTE} ${DATA0IFUUID} phy-flat
system host-unlock ${COMPUTE}


My Example:
