This document provides a sample configuration for a Cisco TN3270 Server that is using session switching with a Dependent Logical Unit Requester (DLUR) and a Dependent Logical Unit Server (DLUS) that is using static links and dynamic Physical Units (PUs).
There are no specific requirements for this document.
This document is not restricted to specific software and hardware versions.
The information in this document was created from the devices in a specific lab environment. All of the devices used in this document started with a cleared (default) configuration. If your network is live, make sure that you understand the potential impact of any command.
For more information on document conventions, refer to Cisco Technical Tips Conventions.
In this section, you are presented with the information to configure the features described in this document.
Note: To find additional information on the commands used in this document, use the Command Lookup Tool (registered customers only) .
This document uses this network setup:
This is in place for this sample configuration:
Two Logical Partitions (LPARs) that are running Multiple Virtual Storage (MVS) in an Enterprise System Connection (ESCON) Multiple Image Facility (EMIF) mainframe:
LPAR #1: MVS1 System. This system should be configured as a Network Node (NN) only.
LPAR #2: MVS2 System. This system should be configured as an NN and a primary DLUS.
No Advanced Peer-to-Peer Networking (APPN) subsystem on the Router, except for the Cisco TN3270 Server DLUR, which is used as an end node.
The Cisco TN3270 Server Listening IP address 172.26.19.99 connected to the DLUS (MVS2).
Static links configured under the Cisco TN3270 Server DLUR for connection to the MVS1 and MVS2.
MVS1 connected to MVS2 through the Channel To Channel (CTC) link.
Control Point to Control Point (CP-CP) Connection established between MVS1 and MVS2 over the CTC link via Multi-Path Channel (MPC). (Transport Resource List [TRL] and LOCAL Major Node definitions are required in MVS1 and MVS2.)
