Network interface description (NWID)
This is a required parameter.
Specifies the name of the network interface description.
- network-interface-description-name
- Specify the name of a network interface description.
Resource name (RSRCNAME)
This is a required parameter.
Specifies the resource name that identifies the hardware that the description represents.
Note: Use the Work with Hardware Resources (WRKHDWRSC) command with *CMN specified for the TYPE parameter to help determine the resource name. Specify the resource name of the communications port. The resource name consists of the input/output adapter (IOA) resource name and the port number on the IOA. For example, if the resource name of the IOA is LIN01 and the port on the IOA is 1, then the resource name is LIN011.
- resource-name
- Specify a resource name.
Online at IPL (ONLINE)
Specifies whether this object is automatically varied on at initial program load (IPL).
- *YES
- The network interface is automatically varied on at initial program load (IPL).
- *NO
- This network interface is not automatically varied on at IPL.
Vary on wait (VRYWAIT)
Specifies whether the network interface is varied on asynchronously or synchronously. For synchronous vary on, specifies how long the system waits for the vary on to complete.
- *NOWAIT
- The system does not wait for the vary on to complete. The network interface is varied on asynchronously.
- vary-on-wait
- Specify the time (in seconds) to wait. Valid values range from 15 through 180. The system waits until the network interface is varied on, or until the specified time passes, before completing the Vary Configuration (VRYCFG) command.
Notes:
- Specifying a wait time in the network interface description affects system IPL time, if ONLINE(*YES) is used, by the amount of time it takes to synchronously vary on the network interface or reach the wait-time value.
- The time required to vary on a network interface is the time it takes to put tasks in place to manage the network interface, to activate the communications I/O processor (IOP) (including downloading the IOP model-unique Licensed Internal Code), and to establish communications with the data circuit-terminating equipment (DCE). Normal vary-on time ranges from 5 through 45 seconds, but can be longer, depending on the system, network interface protocol, and other factors.
Data link connection ID (DLCI)
Specifies the data link connection identifiers of the line descriptions for the frame relay network interface being created.
- *NONE
- No data link connection identifier is specified.
Element 1: DLCI Number
- DLCI-number
- Specify the DLCI number for the line.
Element 2: Line Description
- line-description
- Specify the DLCI line description.
NRZI data encoding (NRZI)
Specifies whether non-return-to-zero-inverted (NRZI) data encoding is used for modems that are sensitive to certain bit patterns in the data stream. This ensures that the signal does not stay the same for an extended period of time.
Note: All data communications equipment on the line must use the same transmission method.
- *NO
- NRZI data encoding is not used.
- *YES
- NRZI data encoding is used.
Physical interface (INTERFACE)
Specifies the type of physical interface on the input/output adapter (IOA) port.
- *RS449V36
- An RS-499/V.36 physical interface is used. This value is valid only for frame relay and SDLC links.
- *V35
- A V.35 physical interface is used. This value is valid only for frame relay, BSC, and SDLC links.
- *X21
- An X.21 physical interface is used. This value is valid only for frame relay, X.25, and SDLC links.
Clocking (CLOCK)
Specifies the method in which the clocking function is provided for the network interface.
- *MODEM
- The modem provides the clocking.
- *LOOP
- The system inverts the clock from the modem and uses it as the transmit clock on the line.
- *INVERT
- The transmit clock provided by the modem data circuit-terminating equipment (DCE) is inverted before use. This option can be used when having problems with high speed data transmission and the modem (DCE) does not support looped clocking.
Line speed (LINESPEED)
Specifies the line speed in bits per second (bps)
- 1536000
- The line speed is 1536000 bps.
- 56000
- The line speed is 56000 bps.
- 64000

- 128000
- The line speed is 128000 bps.
- 192000

- 256000
- The line speed is 256000 bps.
- 320000
- The line speed is 320000 bps.
- 384000
- The line speed is 384000 bps.
- 448000
- The line speed is 448000 bps.
- 512000
- The line speed is 512000 bps.
- 1024000
- The line speed is 1024000 bps.
- 1536000
- The line speed is 1536000 bps.
- 2048000
- The line speed is 2048000 bps.
- line-speed
- Specify the line speed. Valid values range from 56000 bps through 2048000 bps.
LMI mode (LMIMODE)
Specifies whether the local management interface (LMI) for this adapter is configured as terminal equipment or a frame handler.
- *TE
- The local system is configured to interface with a frame relay network as terminal equipment. The frame relay network must be set to operate at ANSI T1.617 Annex D, to be compatible with system link management frames.
- *FH
- The local system is configured to interface with another system as a frame handler. In this configuration, the local system is performing as the frame relay network.
- *ANNEXA
- The local system is configured to interface with a frame relay network as terminal equipment. The frame relay network must operate as an ITU (previously CCITT) Q.933 Annex A to be compatible with system link management frames.
- *NONE
- The local system is configured to interface with the frame relay network or another system without performing any LMI function.
Polling interval (POLLITV)
Specifies the rate of the polling cycle. The polling cycle consists of a status inquiry message and a status message exchange. The status message includes the status of the DLCI.
- 10
- A polling interval of 10 seconds is used.
- polling-interval
- Specify the polling interval to be used. Valid values range from 5 through 30 seconds.
Full inquiry interval (FULLINQITV)
Specifies the number of polling cycles that occur before a full status inquiry is requested.

Element 2: Recovery Time Interval
- 5
- A 5-second time-out period is used.
- 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.
Other Single Value
- *SYSVAL
- The recovery limits specified in the QCMNRCYLMT system value are used.
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.
