Sample TRLE for VTAM's connection to the IBM S/390 Open Systems Adapter

The following example shows transport resource list (TRL) major node definitions for the two hosts shown in Figure 1. Each TRL major node describes the transport characteristics of the multipath channel that is being used by the APPN host-to-host connection.

PORTNAME on the TRLE statement must match PORTNAME on the XCA Major Node.

A diagram that shows HOST1 and HOST2 are connected with each other across an ATM network.
