The LOCAL_PORTS class displays information about the port interface on
  the local system. This class includes fields such as port name, port
  number, port status, and number of entries in the queues for each port.

1  –  BUFF_DESCR

   Number of buffer descriptors in use.

2  –  CMDS_QUEUED

   Total number of messages, datagrams, and port commands queued for
   transmission at all priorities by the port.

3  –  COUNTER_OWNER

   Name of the process currently using the port traffic counters.

4  –  DGI_MAP

   A 16-bit bit map displayed as four hexadecimal digits. Each bit
   in the map represents a port in the cluster from which datagram
   reception has been disabled.

5  –  DG_OVRHD_SIZE

   Number of bytes of port header, SCS header, and DECnet header
   in a datagram.

6  –  DGS_FREE

  Number of free datagram buffers currently queued for receive commands.

7  –  FORM_CIRCS

   Number of formative circuits (circuits in the process of opening)
   from the port.

8  –  FREE_BUFF

   Number of CI buffer descriptors free for use.

9  –  LB_STATUS

   Loopback status of each cable from the port to the star coupler.
   The field applies only to CI. Possible displays are:

         A-B   Loopback tests pass on paths A and B.
         A-#   Loopback tests pass on path A.
         #-B   Loopback tests pass on path B.
         #-#   Loopback tests failed on paths A and B.
         N/A   Loopback tests are not being done.

10  –  LOG_MAP

  A 16-bit bit map displayed as four hexadecimal digits. Each bit in
  the map represents a port in the cluster for which an error was
  logged. Errors are logged when data provided by the configuration
  database on the local system conflicts with data provided by the
  remote system. When a conflict is discovered and an error is logged,
  virtual circuits to the remote system can no longer be established.

11  –  LP_LD_CLASS

   Hard-coded capacity value of the port, based on the megabits/second
   rate of the interconnect of the port.

12  –  LP_PRIORITY

   Management priority assigned to the port.

13  –  LP_STATUS

   Status of the local port. The port is either online or offline.

14  –  LP_TYPE

   Device type of the port (CI780, CI750).

15  –  MAX_PORT

   Largest port number to which a virtual circuit open is attempted.

16  –  MSGS_FREE

   Number of free message buffers currently queued for receives commands.

17  –  MSG_HDR_SIZE

   Number of bytes of port header and SCS header in a message.

18  –  NAME

   Device name of the local port.

19  –  OPEN_CIRCS

   Number of virtual circuits open from the port.

20  –  POOL_WAITERS

   Number of processes waiting for nonpaged pool resources for
   message buffers.

21  –  PORT_NUM

   Port number assigned to the port.

22  –  PRT_MAP

   A 16-bit bit map displayed as three hexadecimal digits. Each bit in
   the map represents a port in the cluster that has been recognized
   by the host system.

23  –  RSPS_QUEUED

   Total number of responses of all kinds received from the port but
   not yet processed.
