INTRODUCTION

Any management system must support implementation of a set of functions defined by the international standards. First of all it is ITU-T Recommendation X.700 and standard ISO 7498-4, which classify tasks of management systems as five groups:

• Management of a system configuration and naming;

• Error processing;

• Analysis of performance and reliability;

• Security management;

• Accounting management.

For management of network nodes with channel switching of DSS SI2000 the management system Management Node is used, which is connected to controllable objects by means of the management network. Controlling information is transmitted by means of upper layers than the transport one (TCP or UDP), based on the communication protocol IP and the client-server model.

The management node SI2000 MN consists of the application and system software as well as hardware tools. Hardware tools are represented as the computer facility. System software consists of the operating system (Windows 2000), the database management system and some other programs. Application software consists of the set of programs having a convenient table-like graphical interface. This textbook is devoted to capabilities of the management node MN in network management.


Laboratory work №1

Introduction to the management of DSS SI2000

The purpose of the work

Acquaintance with the management system. The study of permissions and capabilities of the system configuration. Switching on/off and restarting the system, the work with hosts file.

Key positions

2.1. General information. For the management of a huge system of nodes, where it’s required the high reliability and readiness, there exists the configuration of a big amount of working places, one of which, depending on the software, is used as the server of Management Node (MN), and others – as clients of MN.

For low capacity systems there is only one working place, where client and server software of MN are installed.

If nodes are not at the same place, the management terminal (MT) is used for emergent maintenance. The terminal has partial software for both the server and the client of MN. The management terminal is used only for emergency work of the management and technical maintenance on site, so it will not be mentioned in this textbook.

For the system management the set of commands “Management Node” is used. They are:

Utilities, for the secure management of additional services of the operating system Windows;

Alarm Monitoring, for the launch of the application Alarm Monitoring;

MN Configuration, for the management node configuration in the window MN Configuration Settings;

MN Login, for providing the access to the initial window of the application Management Login.

For the access to this set of commands the shortcutStart > Programs > Management Node is used.

The group of commands Utilities allows safely managing of additional Services, which are used by the application software of the MN server. The use of commands (excluding the command for displaying of the status of services) is only allowed to system users. The halt instructions (MN Stop) and the run command (MN Start) are used before and after the execution of MN software installation. The access to them is given only to the user mnadmin, who installs any software. For users mnadmin and sysadmin the restart command is intended (MN Restart). But all the users have the access to the command of displaying the current status of services (MN Status).



The application Alarm Monitoring is used for control and view of alarm signals, referred to the controllable objects. The laboratory work №13 is about this program.

The MN configuration is performed at the window MN Configuration Settings, tabs of which allow making:

- MN Server Hostname – the definition of the MN server’s name, where the database server is located and servers of the management applications work as well;

- Managed Objects – the management of controllable objects in the window Alarm Monitoring;

- Alarm Panel – the configuration of the connection of the alarm panel ISA;

- Directory Locations – the choice of the temporary folder location;

- Log File Size Configuration – the set of the working files’ size;

- Documentation Language – the choice of the language of the manual;

- MN Locale – the choice of the management application language;

- Mail Notifications – the management of messages about alarms via e-mail

- Backup– the management of database backups;

- Charge Transfer – the configuration of the transfer of accounts data from the MN to the database of a processing center;

- Time Synchronization – the configuration of the system time synchronization;

- Reboot Time – the set of the time for the automatic restart of the MN server.

For the launch of management applications the main window of Management Login is used.

Before the first start it is necessary to perform the configuration of MN in the window MN Configuration Settings.

2.2. Switching on/off and restarting of MN. The procedures depend on the installed software. If there is only MN client software installed on a computer, the built-in Windows commands are used. And we need to pay attention if there is the server software installed on the computer. It is strongly recommended to use the commands of the secure management of additional MN services (Utilities).

If for switching off and restarting the computer, where the MN server software is installed, the built-in Windows commands are used, there is a possibility to lose some data.

The switching on the MN server is performed by the pressing the Power button with installed software. After the boot of the operating system the logon window appears. Depending on the following actions supposed to be done there exist 2 operation modes of the user:

mnadmin (User Name: mnadmin, Password: mnadmin) – used for the MN management;

sysadmin (User Name: sysadmin, Password: sysadmin) - used for the management of the network nodes with use of MN software.

Besides the auto-restart of the computer, where the MN server is installed, there is also an emergent restart. To do this it is necessary to login as mnadmin or sysadmin and run the command Start > Programs > Management Node > Utilities > MN Restart. If the utility SI2000 System Server is not active or if the data backup is being processed at the same time the computer restart will not happen. In other cases the notifying window about the start of restart will appear. Additional server services will stop MN and the restart of Windows operating system will be executed.

Some commands, available from the management program’s menu, the set of tabs and data in windows depend on the type of the computer. In the reference book all of them are described, but in the program window they can be missing.

The procedure of the switching off the computer depends on the installed software there. If there is only the MN client software, then after closing all windows of all management applications the normal halt is performed. If there is also the installed MN server software (used for the continuous work), besides that it is necessary to login the system as mnadmin and check the status of all connections of MN clients, installed on other computers. It is required to provide the closing of all application windows on active clients and to shut down sessions in such a way.

2.3. Hosts file. For obtaining the correspondence of symbol names of nodes with IP addresses of their network interfaces the hosts file is used in the MN management system. This file does not have an extension. To view and to edit it the application notepad is used.

The file path is: C:\WINNT\system32\drivers\etc\hosts

In this file in the line with an IP address the node name is written. Here is an example of the hosts file:

# Copyright (c) 1993-1999 Microsoft Corp.

# This is a sample HOSTS file used by Microsoft TCP/IP for Windows.

# This file contains the mappings of IP addresses to host names. Each

# entry should be kept on an individual line. The IP address should

# be placed in the first column followed by the corresponding host name.

# The IP address and the host name should be separated by at least one

# space.

# Additionally, comments (such as these) may be inserted on individual

# lines or following the machine name denoted by a '#' symbol.

192.168.1.196 centrala452

192.168.1.221 onas_320

The symbol # is used to mark comments.
