This read-create VariablePointer value identifies which specific port on the Ethernet NTE GE112 card a pending switch action should be applied to. It exists because the companion switch-action object needs a target port before the requested port switch can be carried out, so this OID is set first to select it. For example, before forcing a protection switch on the Ethernet NTE GE112 card, an operator would point this OID at the specific port OID that needs to be switched, then issue the action through the paired switch-action object.
