One embodiment includes obtaining virtual machine (VM) information for at least one VM. The VM information includes a VSI type identification (ID) associated with each VM. A policy discriminator (PD) is associated for each VSI type ID, where the PD represents scalable policy assignment. At least one rule and bandwidth filter information associated with a VSI type ID is retrieved from virtual station interface (VSI) database (DB) information and PD for each VSI type ID. The associated at least one rule and filter information is applied based on one of multiple PD types. The multiple PD types comprise a VM type and a virtual local area network (vLAN) type.
