Create Line Desc (Token-Ring) (CRTLINTRN)

The Create Line Description (Token-Ring Network) (CRTLINTRN) command creates a line description for a token-ring network line.

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

Parameters

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 hardware 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. 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.

*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 description used.

Specify the resource name of the communications port.

This is a required parameter.

NWI type (NWITYPE)

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
