This scenario illustrates the basic router configuration for Dependent Logical Unit Requestor/Dependent Logical Unit Server (DLUR/DLUS) over Cisco MultiPath Channel (CMPC) and relates the router configuration to the settings of the 3270 client, to the OS/390 Input/Output Configuration Program (IOCP) generation commands, and to the TRL Major Node, the Local Major Node, and the physical unit's (PU's) Switched Major Node definitions in Virtual Telecommunications Access Method (VTAM). Figure 1 and Figure 2 show the network setup for DLUR/DLUS over CMPC test. Figure 3 details the relationship between configuration parameters. In this scenario, the Channel Interface Processor (CIP) connects to the host via an ESCON Director and the router connects to the PC via Token Ring. This document assumes knowledge of the command structure but not the parameter relationships.
