This scenario illustrates the basic Dependent Logical Unit Requestor/Dependent Logical Unit Server (DLUR/DLUS) configuration of the router and relates the router configuration to the OS/390 Input/Output Configuration Program (IOCP) generation commands and the XCA Major Node and Switched Major Node definitions in Virtual Telecommunications Access Method (VTAM). Figure 1 and Figure 2 show the network setup for DLUR/DLUS test. Figure 3 details the relationship between configuration parameters. In this scenario, the Channel Interface Processor (CIP) is connected to the host via an ESCON Director and the routers are connected by Token Ring. This document assumes knowledge of the command structure but not the parameter relationships.
