IST1503I

Explanation
 VTAM® issues
this message in response to the DISPLAY TRL, TRLE=trl_entry_name or
a DISPLAY ID=trl_entry_name command when trle_name is
the name of the dynamically created TRLE that defines the XCF connection
between two VTAMs. This message is also issued in response to a DISPLAY
TRL, XCFCP=cp_name command.
 When
MPC connectivity exists, message IST1221I is normally displayed. XCF
TRLE's do not have device addresses as MPC TRLEs have and thus, only
the XCF token and the status of the XCF TRLE are displayed. Message
IST1503I will be issued instead of message IST1221I to display XCF
connection status. A complete description of the message group follows
the example.  IST075I NAME=name, TYPE=type
IST486I STATUS=currentstatus, DESIRED STATE=desiredstate
IST087I TYPE = line_type, CONTROL = line_control, HPDT = hpdtvalue
IST1503I XCF TOKEN = token     STATUS = status
IST1502I ADJACENT CP = CP_name_of_other_side
IST314I  END
IST075I  name is the name of the resource or ID type
that is displayed.

 See Node and ID types in VTAM messages for a description
of type. IST087I  This message is part of several different message groups that VTAM issues in response to DISPLAY
commands.
line_type is LEASED.
line_control is XCF.
hpdtvalue can be one of the following:  YES
Indicates the connection is capable of performing channel I/O
directly to or from communications storage manager (CSM) buffers.
NO
Indicates the connection is not capable of performing channel
I/O directly to or from communications storage manager (CSM) buffers.
*NA*
Is displayed when line_control is not MPC or
when the connection is not active.

 IST486I  This message displays the status of the XCF TRLE entered on the
DISPLAY command.
currentstatus is the current status of the
node. See the z/OS Communications Server: IP and SNA Codes for a description of currentstatus. 
desiredstate is the node state that is desired.
See the z/OS Communications Server: IP and SNA Codes for a description of desiredstate.
If VTAM cannot determine the
desired state, desiredstate will be

 IST1502I  CP_name_of_other_side identifies the CP name
of the VTAM on the other side
of this XCF connection which is represented by the TRLE in message
IST075I.

 IST1503I  token is the XCF token MVS™ assigned to the adjacent VTAM.
status is the condition or state of the XCF
connection.
Valid values for the status are:  ACTIVE
Connection is active.
INOP
Connection is inoperative.
RESET
Connection is not ready.

System action
  Processing continues.

Operator response
