An FDDI Port entity represents an access point to the service offered by
   the FDDI module.  A client transmits and receives data through a port.
   Ports are created and deleted by client use of open and close service
   interface procedures.

     MULTICAST OCTETS RECEIVED

         Number of multicast user data octets successfully received and
         available to the data-link user.

     MULTICAST OCTETS SENT

         Number of multicast user data octets successfully transmitted using
         the port.

     MULTICAST PDUS RECEIVED

         Number of multicast frames successfully received and available to
         the data-link user.

     MULTICAST PDUS SENT

         Number of multicast frames successfully transmitted using the port.

     OCTETS RECEIVED

         Number of user data octets successfully received and available to
         the data-link user.

     OCTETS SENT

         Number of user data octets successfully transmitted using the port.

     PDUS RECEIVED

         Number of frames successfully received and available to the data
         link user.

     PDUS SENT

         Number of frames successfully transmitted using the port.

     UNAVAILABLE USER BUFFERS

         Number of times no user buffer was available at the port for an
         incoming frame.

     CLIENT

         Name specified by the data link when the port is opened.

     ETHERNET PROTOCOL TYPES

         Set of Ethernet protocol types that are recognized for this port.
         Protocol types for a port may be enabled and disabled by the user at
         any time during the port's existence.

     LENGTH PRESENT

         Indicates whether the data link is to add a length field on
         transmit, and both assume the presence of and remove the length
         field on receive for Ethernet frames.  This attribute is irrelevant
         for ISO 8802-3 formatted frames because the length field is always
         present.  This is specified by the user when the port is opened.
         The value true means length fields are added and removed by the
         data link.

     LINK

         Name of the link subentity associated with this port, specified by
         the user when the port is opened.

     LLC SAP ADDRESSES

         Set of SNAP protocol identifiers that are recognized for this port.
         LLC SAP addresses for a port may be enabled and disabled by the user
         at any time during the port's existence.

     LLC SERVICE

         LLC PDU processing the data-link user requires from the port,
         specified by the user when the port is opened.This is either LLC
         Class 1, where the entire LLC protocol is handled by the data link,
         or user-supplied LLC, where the user is responsible for operating
         part of the LLC protocol.

     MAC ADDRESSES

         Set of individual and multicast MAC addresses that are recognized
         for this port.  MAC addresses for a port may be enabled and
         disabled by the user at any time during the port's existence.

     RECEIVE MODE

         Indicates if the port is to receive all frames regardless of format,
         Ethernet protocol type, SNAP protocol identifier, LLC SAP address,
         or MAC address.  Promiscuous receipt is enabled and disabled by the
         user.  Support of promiscuous mode is optional.

     SNAP PROTOCOL IDENTIFIERS

         Set of SNAP protocol identifiers that are recognized for this port.
         Protocol identifiers for a port may be enabled and disabled by the
         user at any time during the port's existence.

     TYPE

         Type of port LLC or SMT.
