A user friendly name for this port that may be used to facilitate user selection of a port on a multi-port network system, in the locale specified by 'ppmGeneralNaturalLanguage'. This port name may contain non-ASCII characters that are NOT allowed in a URI (RFC 3986) without percent-encoding. The value of this object SHOULD be unique across all ports on this network system and SHOULD be meaningful to end users (e.g., 'PrinterXYZ-LPR-Duplex'). The value of this object SHOULD be set by an out-of-band method (e.g., local console) during installation (by the vendor or site administrator) and SHOULD NOT be subsequently modified, so that the value can be used as a static key for access to the port. The charset of this text string object is UTF-8 (RFC 3629), in order to support names that cannot be represented in US-ASCII.
