Introduction
This document provides a sample configuration for multiple downstream physical units (DSPUs) that are connected to an upstream front-end processor (FEP).
Prerequisites
Requirements
There are no specific requirements for this document.
Components Used
The information in this document is based on Communications Manager/2 (CommMgr/2) that is running on OS/2.
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.
Conventions
For more information on document conventions, refer to the Cisco Technical Tips Conventions .
Design Notes
-
These configurations use Remote Source-Route Bridging (RSRB). DSPU can be used over Data Link Switching Plus (DLSw+) (recommended) using Virtual Data-Link Control (VDLC).
-
DSPU is configured to use dedicated Logical Unit (LU) resources and allow connections from devices with listed Exchange Identifications (XIDs).
-
A Multiple DSPU to Upstream FEP Sniffer Trace was taken between CommMgr/2 and RouterB.
Configure
In this section, you are presented with the information to configure the features described in this document.
