This document describes how to configure a router and a mainframe computer to use Systems Network Architecture Switching Services (SNASw) over Data-Link Switching (DLSw), to connect upstream to the mainframe and downstream to a legacy Physical Unit (PU) 2.0 node. In this document???s example, the upstream connection to the mainframe is through a Channel Interface Processor (CIP), and the PU 2.0 node connects to the mainframe over the Dependent Logical Unit Requester (DLUR) pipe established by SNASw.
There are no specific requirements for this document.
The information in this document is based on these software and hardware versions:
SNASw 4700 with Cisco IOS?? Software Release 12.1(7)
CIP 7507 with Cisco IOS Software Release 12.1(7)
Downstream Physical Unit (DSPU) 4700 with Cisco IOS Software Release 12.0(10)
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:
The DSPU is only used to bring up a PU on the Token Ring. Note that the remote MAC (rmac) to which it connects is the MAC address that is specified on the Virtual Data-link Control (VDLC) port that is defined to SNASw on Brachio.
This document uses these configurations:
A link statement is required only for the upstream connection, and only one VDLC port definition is needed by both the upstream and the downstream connections.
