Displays the status and LAT characteristics of ports on the local
node.
Format
SHOW PORT [port-name]
1 – Parameter
port-name
Specifies the name of the port for which information is
displayed. If you do not specify a port name, the SHOW PORT
command displays the characteristics for all LTAn: ports on a
node.
Do not use the /APPLICATION, /DEDICATED, /FORWARD, or
/INTERACTIVE qualifiers with a specific port name.
In addition do not use the /LIMITED qualifier with a specific
port name.
2 – Qualifiers
2.1 /APPLICATION
Generates a display of all application ports.
2.2 /BRIEF
Displays port type, port status, and the remote node name, port,
and service associated with the port. This is the default if you
do not specify a port name with the SHOW PORT command.
2.3 /COUNTERS
Displays the counters kept for the port. Do not use the /BRIEF or
/FULL qualifiers with this qualifier.
2.4 /DEDICATED
Generates a display of all dedicated ports.
2.5 /FORWARD
Generates a display of all LAT ports used for either outgoing LAT
connections or local LAT management functions.
2.6 /FULL
Displays the following information:
o Port type
o Port status
o Target port name, node name, and service name associated with
the port
o Remote node name, port, and service associated with the port
if a connection is currently active
For more information, see the description of the SHOW PORT/FULL
example.
2.7 /INTERACTIVE
Generates a display of all LAT ports used for incoming
interactive connections.
2.8 /LIMITED
Generates a display of all limited LTA devices on the system
(previously established with the CREATE PORT /LIMITED or SET PORT
/LIMITED command).
3 – Examples
1.LATCP> SHOW PORT /FULL
The SHOW PORT command in this example produces the following
type of display. The display reflects the characteristics set
by the command examples given with the SET PORT command.
Local Port Name: _LTA16: Local Port Type: Forward
Local Port State: Inactive

Target Node Name: TS33EW Actual Node Name: TS33EW
Target Service Name: Actual Service Name:
--------------------------------------------------------------
The display in this example shows information about all the
ports on the local node. The display shows information for each
of the four types of ports:
o Forward: a port used for outgoing LAT connections or for
executing local management functions and LATCP commands.
Port LTA16: is a forward port. The display shows that the
port is currently inactive-no current LAT connection exists.
The target node name of LATCP$MGMT_PORT indicates that LATCP
is using this port to execute the LATCP commands entered
by the user. If the display listed a node and service name,
it would mean that the port is being used for an outgoing
connection.
o Interactive: a port created as a result of an incoming LAT
connection request from another node or terminal server.
Port LTA17: is an interactive port connected with port PORT_
1 on the terminal server MY_DS200_SERVER.
o Application: a port used for solicited connections to
devices on terminal servers or to application services on
remote LAT service nodes. Port LTA22: is an application
port. The port maps to port LN02 (a printer) on a terminal
server node TS33EW. The display indicates that server TS33EW
queues connection requests from the local node. Port LTA19:
is also an application port. The port maps to the service
PRINTER on terminal server TLAT1.
o Dedicated: a port dedicated to a local application service.
Port LTA21: is dedicated to the service GRAPHICS.
The target port name, target node name, and target service
name are the names specified with the SET PORT command. They
are passed to the remote node or terminal server when the
connection request is made.
The actual port name, actual node name, and actual service name
are the names returned by the remote node when it accepts the
connection request. They may differ from the corresponding
target names (specified with the SET PORT command) if the
remote node translates the names. For example, terminal servers
that accept connections to LAT service names usually return the
name of the port to which the connection was actually directed.
2.LATCP> SHOW PORT LTA1 /COUNTERS
The SHOW PORT /COUNTERS command in this example produces a
display that lists counter information for the LTA1 device.
