vrn

vrn

Use the vrn DLUR SAP configuration command to tell the SNA session switch which connection network the internal adapter interface on the CIP card belongs to. Use the no form of this command to remove a network name.

vrn vrn-name

no vrn

Syntax Description

vrn-name Fully qualified virtual routing node (VRN) name.

Default

The adapter is not considered to be part of a connection network.

Command Mode

DLUR SAP configuration

Usage Guidelines

The vrn command is used to discover routes without having to configure all possible links.

A connection network is also known as a shared-access transport facility (SATF). This means, at the MAC level, that all nodes in the network can reach each other using the same addressing scheme and without requiring the services of SNA session routing. A bridged LAN (whether source-route or transparent) is an example. Such a network is represented in the APPN topology as a kind of node, termed a VRN.

To make use of this function, all APPN nodes must use the same VRN name for the SATF.

Refer to the VTAM operating system documentation for your host system for additional information regarding the VTAM VNGROUP and VNNAME parameters on the PORT statement of an XCA major node.

Several parameters in the DLUR configuration mode consist of fully qualified names, as defined by the APPN architecture. Fully qualified names consist of two case-insensitive alphanumeric strings, separated by a period. However, for compatibility with existing APPN products, including VTAM, the characters “#” (pound), “@” (at), and “$” (dollar) are allowed in the fully qualified name strings. Each string is from one to eight characters long; for example, RA12.NODM1PP. The portion of the name before the period is the NETID and is shared between entities in the same logical network.

Example

The following command sets a VRN name for the TN3270 internal adapter on the CIP:

vrn SYD.BLAN25
