Introduction

This document provides a sample configuration for configuring downstream physical unit (DSPU) to upstream front-end processor (FEP).

Prerequisites

Requirements

There are no specific requirements for this document.

Components Used

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.

Conventions

Refer to Cisco Technical Tips Conventions for more information on document conventions.

Configure

This example uses remote source-route bridging (RSRB). DSPU can be used over DLSw+ (recommended) using Virtual Data-Link Control.

DSPU is configured to use pooled LU resources and allow connections from any device specifying the correct XID and LSAP.

Note:  Sniffer trace taken between CommMgr/2 and RouterB.
