Create Line Desc (Ethernet) (CRTLINETH)

The Create Line Description (Ethernet) (CRTLINETH) command creates a line description for an Ethernet line.

Restriction: You must have input/output system configuration (*IOSYSCFG) special authority to use this command.

Common Errors for CRTLINETH

In order to avoid common configuration errors, determine the port configuration of your switch or hub prior to configuring your line description. The line description parameters and the port configuration must match in order for operating system to communicate properly with the network.

Use the following guidelines when configuring your line description:

One frequent cause of problems is a mismatch between the duplex setting of an auto-negotiation capable adapter and the switch or hub. In the case of auto-negotiation, duplex is not detectable by either the switch, hub, or the auto-negotiation capable adapter. So, there is no way to notify the user of a mismatch. Symptoms of a duplex mismatch include:

The following are common reference codes:

A6E3
Duplex mismatch, cable problems, or an auto-negotiation timeout
A6F4
Unable to establish link, line speed mismatch, duplex mismatch, or no cable.
A42B
The switch or hub did not participate in auto-negotiation. A good link may not be established. The line description should be reconfigured to match the switch or hub.

Line description (LIND)

Specifies the name of the line description

This is a required parameter.

Resource name (RSRCNAME)

Specifies the resource name that identifies the communications port.

Note: Use the Work with Hardware Resources (WRKHDWRSC) command with *CMN specified for the TYPE parameter to help determine the resource name. The resource name is on the port. For example, the resource name may be CMN01 on an Ethernet port.

Note: The value specified on the RSRCNAME parameter cannot be changed from *NWSD to another value or from another value to *NWSD.

Note: The value specified on the RSRCNAME parameter cannot be changed from *AGG to another value or from another value to *AGG.

*AGG
The resource name specified is an aggregate line. It represents one or more physical resources.
*NWID
The resource name specified on the attached frame relay network interface description is used.
*NWSD
The resource name is determined by the network server used.
name
Specify the resource name of the communications port.

This is a required parameter.

Bridge identifier (BRIDGE)

Specifies the bridge identifier this Ethernet line description is associated with.

A bridge identifier allows a server partition to effectively share a single physical Ethernet adapter with several client partitions, each of which has only a virtual Ethernet adapter. Not all Ethernet line descriptions support bridging.

*NONE
This line description is not associated with any bridge.
name
Specify the name of the bridge identifier that this Ethernet line description is associated with.

Online at IPL (ONLINE)

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

*YES

Vary on wait (VRYWAIT)

Specifies whether the line is varied on asynchronously or synchronously. For synchronous vary on, this parameter specifies how long the system waits for the vary on to complete.

*NOWAIT
The system does not wait for vary on completion. The line 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 line is varied on, or until the specified time passes, before completing the Vary Configuration (VRYCFG) command.

Notes:

  1. When ONLINE(*YES) is used, specifying a wait time in the line description affects system IPL time. In such cases, system IPL time is influenced by the amount of time required to synchronously vary on the line or reach the wait-time value.
  2. The time required to vary on a line is the time it takes to:
    • Put tasks in place to manage the line
    • Activate the communications I/O processor (IOP), including downloading the IOP model-unique Licensed Internal Code
    • Establish the communications tasks and processes

Normal vary-on time ranges from 5 through 45 seconds, but can be longer, depending on the system, line protocol, and other factors.

*SRCPORT
The adapter selection algorithm uses the source TCP/IP or UDP port value.
*DESTPORT
The outgoing adapter path is selected via an algorithm using the destination TCP/IP or UDP port value.
*SRCDESTP
The outgoing adapter path is selected via an algorithm using the combined source and destination TCP or UDP port values.

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.

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 Ethernet Line Description

CRTLINETH   LIND(BOSTON)  RSRCNAME(LIN041)
