CSNA Configuration Relationships

This scenario illustrates the Cisco SNA (CSNA) configuration of the router and relates the router configuration to the XCA Major Node and Switched Major Node definitions of Virtual Telecommunications Access Method (VTAM), the OS/390 Input/Output Configuration Program (IOCP) generation commands, and the PC setup. Figure 1 shows the major configuration parameters of the Channel Interface Processor (CIP) and the Token Ring interfaces and how they are logically combined using the source-bridge command. Figure 2 details the relationships between configuration parameters. In this scenario, the CIP connects to the host via an ESCON Director and the PC establishes a Logical Link Control type 2 (LLC2) session with the host via Token Ring using CSNA in the router. This document assumes knowledge of the command structure but not the parameter relationships.
