2.3.15 Testing the Network State

This topic describes how to check the connectivity of a network and whether the host is reachable, and check all gateways passed by data packets sent from a host to the destination. In addition, this operation enables you to locate network faults.

Background Information

The commands used to test the network state include ping and tracert.

l ping

To check the network connectivity and the host reachability, run the ping command.

l tracert

To send test packets from the transmit host to the destination host, run the tracert command.

With this command, you can check the connectivity of a network and locate faults in the network.

The following section describes the execution process of the tracert command:

1. The host sends a packet with the Time to Live (TTL) of 1 to the destination.

2. During the first hop, the system returns an Internet Control Message Protocol (ICMP) packet to indicate the failure in sending the packet due to TTL timeout.

3. The host sends a packet with the TTL of 2. The system also returns TTL timeout during the second hop.

The process continues in this manner until the packet reaches the destination.

In this way, the system can record the source address of each ICMP TTL timeout message, and provide a path along which an IP packet reaches the destination.

Procedure

l Run the ping command to test the network state.

l Run the tracert command to test the network state.

Examples

To test the connectivity of a network by using the ping command, do as follows:

huawei(config)#ping 10.11.52.240

3 Network Management Configuration

About This Chapter

This topic describes how to manage the MA5600T through the N2000, and the related configuration operations.

NOTE

This document describes the configuration on the MA5600T. Each chapter provides an overview of the service configuration, describes the configuration flow with one or more configuration examples, and then provides a detailed description of the basic operations that can be performed on the MA5600T.

For the readers who are familiar with the MA5600T, it is recommended that you read the configuration example (s) directly.

For the readers who are not familiar with the MA5600T, it is recommended that you read the basic operations first.

3.1 Overview

This topic describes the network management protocols, and the NMS that the MA5600T supports.

3.2 Basic Concepts

This topic describes the concepts in the network configuration.

3.3 Configuration Example of an Outband NMS

This topic describes how to connect the MA5600T to the N2000 through the maintenance network port. Then, you can maintain and manage the MA5600T through an outband management channel. In the outband NMS mode, the non-service channel is used to transmit the management information. In this case, the management channel is separated from the service channel, and a more reliable device management channel is provided compared with the inband NMS mode. Thus, when the MA5600T is faulty, the information about the device in the network can be located in time, and the real-time monitoring can be performed.

3.4 Configuration Example of an Inband NMS

This topic describes how to connect the MA5600T to the N2000 through the GE port. You can then maintain and manage the MA5600T through an inband management channel. In the inband NMS mode, the NMS interactive information is transmitted through the service channel of the device. For the flexible networking of the inband NMS mode, no additional device is required.

Thus, it saves cost, however, it is not easy to maintain.

3.5 SNMP Agent Configuration

This topic describes how to configure an SNMP agent when you need to maintain the MA5600T through the manager.

3.6 Configuring the IP Address of the Outband NMS Interface

This topic describes how to configure the IP address of the outband NMS interface (maintenance network port).

3.7 Configuring an NMS Route

This topic describes how to create a static route between the MA5600T and the manager.

3.8 Configuring the IP Address of the Inband NMS Interface

This topic describes how to configure the IP address of the inband NMS interface.

3.1 Overview

This topic describes the network management protocols, and the NMS that the MA5600T supports.

Service Description

Based on the Simple Network Management Protocol (SNMP), the MA5600T communicates with the NMS through its network management interface. Here, the iManager N2000 Fixed Network Integrated Management System (N2000) is used as the NMS.

The N2000 can manage and maintain the MA5600T through the network port of the MA5600T. The MA5600T uses traps to send the status information to the N2000 to report configuration changes or emergency events.

Service Specification

This topic describes the network configuration performed on the MA5600T to realize normal communication between the MA5600T and the N2000, including outband NMS configuration and inband NMS configuration.

NOTE

To realize normal communication between the MA5600T and the N2000, you must also configure on the N2000. For more information, refer to the MA5600T Commissioning Guide.

3.2 Basic Concepts

This topic describes the concepts in the network configuration.

SNMP

The SNMP is an existing network management protocol. It includes the following two parts:

l Network management workstation

l Agent

The SNMP ensures normal transmission of administrative message between any two points. It facilitates the following administrative operations on any node of the network:

l Retrieving information

l Modifying information

l Locating a fault

l Diagnosing a fault

l Planning the capacity

l Generating a report
