Introduction

This document provides a sample configuration for an inband IP management link. In some cases, you do not have access to the Ethernet interface on the Processor Switch Module 1 (PXM1) for management purposes. This document describes how to build a permanent virtual circuit (PVC) that terminates on the PXM for the purposes of managing the MGX 8250.

Prerequisites

Requirements

Before you attempt this configuration, ensure that you meet these requirements:

• Knowledge of the MGX 8250 and modules

Components Used

The information in this document is based on the software and hardware versions below.

• MGX 8250

• PXM1

The information presented in this document was created from devices in a specific lab environment. All of the devices used in this document started with a cleared (default) configuration. If you are working in a live network, ensure that you understand the potential impact of any command before using it.

Conventions

Configure

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) .

Network Diagram

This document uses the network setup shown in the diagram below.

Configuring

Complete the following steps to configure an inband IP management link:

1. Use the cnfifip command to configure an IP address for the ATM interface:

   mgxish06.1.7.PXM.a > cnfifip 37 1.1.1.2 255.255.255.0 1.1.1.255
   
   switchmMgmtIpAddr(0x01010102)

2. Use the addcon command to add a master connection from your inbound port to port 7.34 on the PXM.

   Note: In this example, we are using the DS3 port 7.1 on the PXM as our inbound port. You can also build connections from other cards, for example, through an AUSM.

   mgxish06.1.7.PXM.a > addcon 1 2 1 40 4 2 1 mgxish06.7.34.1.40
        Connection ID: mgxish06.0.1.1.40

3. Use the cnfupcubr command to adjust the policing parameters; some code versions default the peak cell rate (PCR) to 50.

   mgxish06.1.7.PXM.a > cnfupcubr 1.1.40 5 1000 1000 100
   

4. Use Telnet to access and manage the MGX 8250 over the ATM link over vpi/vci 1/40.

Verify
