Parameters

procname
The member name of the cataloged procedure used to start the SNALINK LU6.2 interface.
CANCEL
Cancels the SNALINK LU6.2 interface by a user abend. The system produces a dump and writes it to the data set defined by the //SYSUDUMP DD statement in the cataloged procedure.
DROP
Ends the connection with the destination nodes as specified.
IP=dest_ip
The destination IP address of the connection to end.
LU=dest_lu
The destination LU name of the connection to end. For dependent LU connections, either the sending or receiving remote LU name can be supplied and both sessions are ended.
ALL
Drops all connections defined in SNALINK LU6.2 configuration data set.
HALT
Shuts down the SNALINK LU6.2 interface.
LIST
Displays status and traffic information for the range of connections specified.
ACTIVE
The range of destinations to be listed. Information is displayed for all currently established connections handled by the specified address space. This is the default.
IP=dest_ip
The destination IP address of the connection to be listed.
LU=dest_lu
The destination LU name of the connection to be listed. For dependent LU connections, you can supply either the remote sending or receiving LU name.
ALL
Displays information for all destinations defined in the SNALINK LU6.2 configuration data set.
RESTART
Establishes one or more connections to destination nodes. Any destinations in the specified range that are already connected are skipped.
INIT
The range of connections to be established. If the INIT parameter is specified, connections are established with all destinations defined with the INIT parameter in the SNALINK LU6.2 configuration data set. If the RESTART subcommand is entered without parameters, the INIT option is the default.
IP=dest_ip
The destination IP address of the connection to be established.
LU=dest_lu
The destination LU name of the connection to be established. For dependent LU connections, either the remote sending or receiving LU name can be supplied and both sessions are established.
ALL
The range of connections to be established. If the ALL parameter is specified, connections are established with all destinations defined in the SNALINK LU6.2 configuration data set.
TRACE
Alters the levels of trace defined in the SNALINK LU6.2 configuration data set while the address space is active.
ON
Enables a basic level of tracing for all connection in the specified range. The default is ON.
OFF
If the OFF parameter is specified, tracing is disabled for all connections in the specified range.
DETAIL
Enables a detailed level of tracing for all connections in the specified range.
IP=dest_ip
The destination IP address associated with the connection for which tracing will be enabled or disabled.
ALL
If the ALL parameter is specified, tracing for all destinations (either currently or subsequently connected) is set to the requested level.

Examples

To enable tracing for the procedure LU62PROD on connection associated with 9.163.37.12, enter 
F LU62PROD, TRACE IP=9.163.37.112
The following example illustrates the output you might get if you issued the MODIFY command with the LIST parameter: 
MODIFY TCPIPL62,LIST ALL
 
    TCPL62217I LIST Accepted; Range = All Connections
    TCPL62212I   192.9.207.39 (Connected on 92.013 at 09:52:11)
    TCPL62213I     Connected by:  DATA             Trace Level: OFF
    TCPL62214I     SEND:-  Status: Not Allocated    Packets Out: 0
    TCPL62215I     RECV:-  Status: Allocated        Packets In:  0
    TCPL62211I   192.9.207.40 (Disconnected on 92.013 at 08:30:10)
    TCPL62210I   192.9.207.41 (Disconnected)
    TCPL62219I LIST Completed
