This read-create VariablePointer object identifies which specific port on the Ethernet NTE GE112ProM Card the paired switch-port-action object should act on. Because the Ethernet NTE GE112ProM Card exposes more than one port, this pointer is what scopes a subsequent switch action to one particular port rather than the whole card, so it must be set correctly first. Before switching traffic away from a failing port on the Ethernet NTE GE112ProM Card, an admin would first write this object to point at that exact port's OID so the switch action that follows targets it and not a different port on the same card.
