This object returns an OID referencing an object which uniquely corresponds to this remap port. The only criteria is that this OID is a leaf, and that it exists and is accessible. For example, if remap functionality is running on an 802.1d compliant bridge, remap port #1 could reference dot1dBasePort.1. Alternatively you could reference a mib2 interface like ifIndex.1 or a Cabletron Secure Fast port. Mixing these types (some refer to bridge ports, others refer to SFS ports) is not advised, but not prohibited
