This read-create VariablePointer points to the physical or logical port on the network side of the Ethernet Flow, such as a Network Port, Network LAG, Network Split Horizon Group, ERP, or Protection Group. For a Transparent Flow, it instead specifies the flow's Network-2 side. For example, an administrator points cmFlowPort2 at a Network LAG so the flow's network-side traffic egresses across the aggregated link rather than a single port.
