Note: If *HPRIP is specified, a value must be specified for the RMTINTNETA parameter.

*ILAN

This controller does not use a communication line since all communications are within the system. This link type allows multiple operating systems (running on one physical system) to communicate without requiring a physical communications link.

Note: If LINKTYPE(*ILAN) is specified, the value specified for NODETYPE must be *LENNODE or *NETNODE and the value specified on the SSAP parameter must be different than the value specified on the DSAP parameter.

*LAN

This controller is attached to a distributed data interface (DDI), Ethernet, or token-ring local area network line.

*LOCAL

This controller uses no communication lines since all communications are local. If *LOCAL is specified, the following criteria must be met:

• SWITCHED, SNBU, and APPN must remain unspecified or be *NO
• The LINE, MAXFRAME, RMTNETID, RMTCPNAME, EXCHID, CPSSN, NODETYPE, TMSGRPNBR, SSCPID, and ROLE parameters must not be specified
• Parameters relating to SDLC, X.21 short-hold mode, X.25, or LAN configuration must not be specified.
• Since LINKTYPE(*LOCAL) controllers must have APPN(*NO) specified, any attached devices must also have APPN(*NO) specified

*OPC

This controller is attached to the optical bus (OptiConnect).

*SDLC

This controller is attached to a synchronous data link control (SDLC) line.

*TDLC

This controller is attached to a twinaxial data link control (TDLC) line.

*VRTAPPN

This controller is used for APPN communications. It is not attached to any specific communications line. If *VRTAPPN is specified, the following criteria must be met:

• SWITCHED and SNBU must remain unspecified or be *NO
• APPN(*YES) must be specified
• The LINE, MAXFRAME, RMTNETID, RMTCPNAME, EXCHID, CPSSN, NODETYPE, TMSGRPNBR, SSCPID, and ROLE parameters must not be specified
• Parameters relating to SDLC, X.21 short-hold mode, X.25, or LAN configuration must not be specified
• Since LINKTYPE(*VRTAPPN) controllers are for supporting APPN communications, any attached devices must have APPN(*YES) specified

*X25

This controller is attached to an X.25 line.

Online at IPL (ONLINE)

Specifies whether this object is automatically varied on at initial program load (IPL).

*YES

The controller is automatically varied on at IPL.

*NO

The controller is not automatically varied on at IPL.

Specifies whether this controller is attached to a switched line, a token-ring network, Ethernet LAN, or an X.25 switched virtual circuit (SVC). *NO must be specified for APPC controllers attached to a TDLC line.

*NO

This controller is attached to a nonswitched line. Specify this value for controllers attaching to an X.25 permanent virtual circuit (PVC).

*YES

This controller is attached to a switched line. Specify this value for controllers attached to an X.25 switched virtual circuit (SVC). Also specify this value for controllers attached to a local area network.

Note: If LINKTYPE is *LAN, the SWITCHED parameter value must be *YES or must not be specified.

Short hold mode (SHM)

Specifies whether this controller is to be used for X.21 short hold mode. To specify *YES, you must also specify *SDLC for the Link type (LINKTYPE) parameter, and *YES for the Switched connection (SWITCHED) parameter.

*NO

This controller is not used for X.21 short hold mode.

*YES

This controller is used for X.21 short hold mode.

Switched network backup (SNBU)

Specifies whether the remote system modem has the switched network backup (SNBU) feature. The backup feature is used to bypass a broken nonswitched (leased line) connection by establishing a switched connection. To activate SNBU, you must change the controller description of the modem from nonswitched to switched by specifying *YES for the Activate swt network backup (ACTSNBU) parameter.

Note: If the modem model you are using is an IBM 386x, 586x, or 786x, you should not change the controller description. Instead, manually switch the modem to the unswitched mode, and manually dial the connection.

Both the local and remote modems must support the SNBU feature to perform a valid activation.

*NO

The remote system modem does not have the SNBU feature.

*YES

The remote system modem has the SNBU feature.

APPN-capable (APPN)

Specifies whether the local system uses advanced peer-to-peer networking (APPN) functions when communicating with this controller. *YES must be specified for APPC controllers attached to a TDLC line.

*YES

This controller is for APPN.

*NO

This controller is not for APPN.

Remote internet address (RMTINTNETA)

Specifies the remote internet address to which the controller will respond.

character-value

The internet address is specified in the form, nnn.nnn.nnn.nnn, where nnn is a decimal number ranging from 0 through 255. Leading zeros in each part of the dotted decimal internet address are invalid and will be removed. An internet address is not valid if it has a value of all binary ones or zeros for the network identifier (ID) or host portion of the address. If the internet address is entered from the command line, the address must be enclosed in apostrophes.

Local internet address (LCLINTNETA)

Specifies the TCP/IP interface to be used to communicate with the remote system.

Note: This parameter is valid only when *HPRIP is specified for the Link type (LINKTYPE) parameter.

*SYS

The system will select the local internet address to use.

character-value

The internet address is specified in the form, nnn.nnn.nnn.nnn, where nnn is a decimal number ranging from 0 through 255. Leading zeros in each part of the dotted decimal internet address are invalid and will be removed. An internet address is not valid if it has a value of all binary ones or zeros for the network identifier (ID) or host portion of the address. If the internet address is entered from the command line, the address must be enclosed in apostrophes.

Alias-name

The alias name is the same value that is specified on the ADDTCPIFC and CHGTCPIFC commands (ALIASNAME parameter).

LDLC timers (LDLCTMR)

Specifies LDLC (Logical Data Link Control) timers and retry count. The LDLC retry count and LDLC retry timer are used in conjunction. The LDLC retry count and LDLC retry timer are initialized when a command or request is first transmitted over the link. If the LDLC retry timer expires before a response is received, the command or request is retransmitted, the LDLC retry count is decremented and the LDLC retry timer is restarted. If the timer expires with the LDLC retry count at zero, the link is assumed to be inoperative. The LDLC liveness timer is used to make sure that both the other endpoint of an RTP (rapid transport protocol) connection and the path between the endpoints are still operational after a period of inactivity.

Specifies the time interval between attempts to establish a connection to the controller.

*CALC

Use the values specified for the X.25 connection timer (X25CNNTMR) parameter and the X.25 connection retry (X25CNNRTY) parameter to determine how often and how many times to try establishing the connection.

X.25-delay-timer

Specify a value ranging from 1 to 32767 units. Each unit represents 0.1 second. Connection attempts are repeated indefinitely at this time interval.

X.25 acknowledgement timer (X25ACKTMR)

Specifies the amount of time to delay sending acknowledgements for received frames.

20

The time allowed to delay sending an acknowledgment is 2 seconds.

X.25-acknowledgment-timer

Valid values range from 1 to 2550 in 0.1 second intervals, or 0 to indicate no delay.

X.25 inactivity timer (X25INACTMR)

Specifies the time period used to determine an inactive condition for the controller. Valid values range from 1 to 2550 in 0.1 second intervals.

1440

The time period used to determine an inactive condition for the controller is 10.5 seconds.

User facilities (USRFCL)

Specifies a string of hexadecimal characters sent to the X.25 network to request additional services. The system allows up to 218 hexadecimal characters.

Recovery limits (CMNRCYLMT)

Specifies the number of recovery attempts made by the system before an inquiry message is sent to the system operator. Also specifies the time (in minutes) that must elapse before the system sends an inquiry message to the system operator indicating that the recovery attempt count limit is reached.

Element 1: Maximum Recovery Limit

2

Two recovery attempts are made within the interval specified.

*SYSVAL

The value in the QCMNRCYLMT system value is used.

count limit

Specify the number of second-level recovery attempts to be made. Valid values range from 0 through 99.

Element 2: Recovery Time Interval

5

The specified number of recovery attempts is made within a 5-minute interval.

time-interval

Specify the time interval (in minutes) at which the specified number of second-level recoveries are attempted. Valid values range from 0 through 120. If the value specified for count-limit is not 0, the value 0 specifies infinite recovery.

More information on communication recovery is in the Communcations Management book, SC41-5406.

Message queue (MSGQ)

Specifies the message queue to which operational messages are sent.

*SYSVAL

Messages are sent to the message queue defined in the QCFGMSGQ system value.

*SYSOPR

Messages are sent to the system operator message queue (QSYS/QSYSOPR).

Qualifier 1: Message queue

name

Specify the name of the message queue to which operational messages are sent.

Qualifier 2: Library

name

Specify the name of the library where the message queue is located.

For more information about using this command, see the Communcations Management book, SC41-5406.

Authority (AUT)

Specifies the authority you are giving to users who do not have specific authority for the object, who are not on an authorization list, and whose group profile or supplemental group profiles do not have specific authority for the object.

*CHANGE

The user can perform all operations on the object except those limited to the owner or controlled by object existence (*OBJEXIST) and object management (*OBJMGT) authorities. The user can change and perform basic functions on the object. *CHANGE authority provides object operational (*OBJOPR) authority and all data authority. If the object is an authorization list, the user cannot add, change, or remove users.

*ALL

The user can perform all operations except those limited to the owner or controlled by authorization list management (*AUTLMGT) authority. The user can control the object's existence, specify the security for the object, change the object, and perform basic functions on the object. The user also can change ownership of the object.

*USE

The user can perform basic operations on the object, such as running a program or reading a file. The user cannot change the object. Use (*USE) authority provides object operational (*OBJOPR), read (*READ), and execute (*EXECUTE) authorities.

*EXCLUDE

The user cannot access the object.

*LIBCRTAUT

The system determines the authority for the object by using the value specified for the Create authority (CRTAUT) parameter on the Create Library (CRTLIB) command for the library containing the object to be created. If the value specified for the CRTAUT parameter is changed, the new value will not affect any existing objects.

name

Specify the name of an authorization list to be used for authority to the object. Users included in the authorization list are granted authority to the object as specified in the list. The authorization list must exist when the object is created.

Examples

Example 1: Creating an APPC controller with link type *SDLC

CRTCTLAPPC   CTLD(OUTLAND)  LINKTYPE(*SDLC)
             APPN(*NO)  LINE(OUTLINE)
             RMTNETID(*NONE)  STNADR(C1)

This command configures an APPC controller description attached to a nonswitched SDLC line with a station address of C1.

Example 2: Creating an APPC controller with link type *HRPIP

CRTCTLAPPC  CTLD(GRIFFIN) LINKTYPE(*HPRIP)
            RMTINTNETA('9.5.5.1') RMTCPNAME(CJP)

This command configures an APPC controller description named GRIFFIN with a link type of *HPRIP, a remote internet address of 9.5.5.1 and a remote control point of CJP.
