Introduction

This document provides a sample configuration for configuring Data Link Switching (DLSw) on serial interfaces at either end of the DLSw peer for a Synchronous Data Link Control (SDLC) to SDLC connection.

Before You Begin

Requirements

Before attempting this configuration, please ensure that you meet these requirements:

  • The router must be running the IBM feature set.

  • The DLSw peers must be configured.

  • Both ends of the connection must be serial interfaces supporting SDLC.

Components Used

This document is not restricted to specific hardware and software versions.

Conventions

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

Configure

In this section, you are presented with the information to configure the features described in this document.
