Port ACL serves as a collection of access control entries or ACL rules. An ACL can be attached to any number (zero or more) of VMM networking primitives, such as a VM network, VM subnet, virtual network adapter, or the VMM management server itself. An ACL can contain any number (zero or more) of ACL rules. Each compatible VMM networking primitive (VM network, VM subnet, virtual network adapter, or VMM management server) can have either one port ACL attached or none.
