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

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:

• If the switch or hub auto-negotiates either the line speed or duplex, specify *AUTO for both the LINESPEED and DUPLEX parameters. Do not specify LINESPEED(100M) or LINESPEED(10M) and DUPLEX(*FULL).
• If the switch or hub does not auto-negotiate either the line speed or duplex, specify the corresponding values on the system. For example, if the switch specifies a line speed of 100M and full duplex, specify LINESPEED(100M) and DUPLEX(*FULL) on the command.

One frequent cause of problems is a mismatch between the duplex setting of an auto-negotiation capable adapter like the 2838 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:

• A6E3, A6F4 reference codes
• Poor performance
• Large numbers of TCP/IP retransmits

The following are common reference codes for 2809 and 2810 IOPs:

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.

*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.

Online at IPL (ONLINE)

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

*YES

The line is automatically varied on at initial program load (IPL).

*NO

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.

In full duplex mode, one cable is dedicated to send data and another cable is dedicated to receive data. Therefore, data can be sent and received simultaneously. A hub is required for full duplex.

Note: For optimum performance, this setting should match the setting on the switch or hub this line is connected to. Refer to iSeries Information Center at http://www.ibm.com/eserver/iseries/infocenter for more information.

When *NWID is specified on the RSRCNAME parameter, and *ALL or *IEEE8023 is specified on the ETHSTD parameter, the valid values for this parameter range from 265 through 1489 bytes. Maximum frame size larger than 1486 or 1489 is valid only when AA SSAP for TCP/IP is specified.

The possible SSAP type values are:
