Configuring the Node

The first step in configuring CS/AIX on a system is to configure the local node. Node configuration provides the basic information that the node needs in order to participate in an APPN network. You must configure the node before you can define connectivity or other resources for the node.

If the node has already been configured, you must stop the node before changing the node configuration.

To configure the node, use one of the following methods:

Motif administration program

Select Configure node parameters from the Services menu on the Node window.

Command-line administration program

Issue the define_node command.

Advanced parameters for node configuration provide control over sessions with undefined partner LUs, reporting of security failures, back-level NMVT support, SNMP support, and limited resource timeouts.

Node Configuration Parameters

You need the following information for node configuration:

APPN support

Level of APPN support for the node:

• If your network is not an APPN network, configure the node as a LEN node.
• To participate in an APPN network in which another node provides session routing services, or to use DLUR only on the local node, configure the node as an end node.
• To provide intermediate routing services in an APPN network, or to provide passthrough DLUR services to downstream nodes, configure the node as a network node.
• To provide session routing services to other nodes in a branch network that are not part of the main APPN backbone network, configure the node as a branch network node.

Control point name

Fully qualified control point name for the local node. Because this name may need to be configured on other nodes in the network, consult with your SNA network planner to determine the name.

When you define the control point, CS/AIX automatically defines a local LU with the same name. That LU can act as a default local LU for the node.

Control point alias

Local alias for the default local LU. Supply this value if the default local LU is used by independent LU 6.2 LUs.

Node ID

Identifier for the PU on the local node. Supply a value only if the node will be used for dependent traffic using the default (control point) LU.

Additional Configuration

After configuring the node, continue with the following configuration tasks:

• Configure connectivity as described in Chapter 5, Defining Connectivity Components.
• Configure node resources (LUs) as described in Chapter 7, Configuring APPC Communication or Chapter 8, Configuring User Applications.
• Configure applications as described in Chapter 8, Configuring User Applications.
