A textual name of this interface. If this system is manageable through SNMP, and supports the object ifName, the value of this object must be identical with that of ifName for the ifEntry of the lowest level physical interface for this port. This interface must be uniquely named on this system to distinguish parallel links with a neighboring system. If this interface does not have a textual name, the value of this object is a zero length string.
