Introduction

This document provides a sample configuration for data-link switching (DLSW+) local switching of Ethernet to Qualified Logical Link Control (QLLC).

Prerequisites

Requirements

There are no specific requirements for this document.

Components Used

The information in this document is based on Cisco IOS® software version 11.1, or greater.

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

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

Note: Use the Command Lookup Tool ( registered customers only) to find more information on the commands used in this document.

Configuration

This document uses this configuration:

• DLSw+ local switching of Ethernet to QLLC

qllc dlsw vmacaddr 4000.2500.0001 
  

bridge 10 protocol ieee 
 


                     

Note: The front-end processor (FEP) is connected to the X.25 network. The X.25 address is 1000621. The MAC address that is assigned to the FEP is 4000.2500.0001. The stations in the Ethernet are configured with a destination MAC address of 0200.A400.0080, which is the bitswapped version of 4000.2500.0001.

If the FEP can also dial out, then the MAC address of the remote device needs to be specified under the X.25 interface using this command:

qllc dlsw partner 4000.3174.0001

This is the MAC address of the remote device 0200.8C74.0080, which is the bitswapped version of 4000.3174.0001, because the remote device is located in an Ethernet network.
