Element Management System

1.1 WiMax Network Overview

1.1.1 EMS Application Overview

The Element Management System (EMS) is a suite of servers and a graphical user interface (GUI) oriented applications that are capable of managing a network of geographically distributed network elements or network devices. This is accomplished by exchanging management data between management consoles at remote sites with a management station at the main site. A distributed architecture also allows personnel to manage their networks from remote sites.

Most element management architectures use the same basic structure and set of relationships. End stations (managed devices), such as computer systems and other network devices, run software that enables them to send alerts when they recognize problems (for example, when one or more user-determined thresholds are exceeded). Upon receiving these alerts, management entities are programmed to react by executing one, several, or a group of actions, including operator notification, event logging, system shutdown, and automatic attempts at system repair.

Management entities also can poll end stations to check the values of certain variables. Polling can be automatic or user-initiated, but agents in the managed devices respond to all polls. Agents are software modules that first compile information about the managed devices in which they reside, then store this information in a management database, and finally provide it (pro actively or reactively) to management entities within element management system (EMS) via a network management protocol. Well-known network management protocols include the Simple Network Management Protocol (SNMP) and Common Management Information Protocol (CMIP). Management proxies are entities that provide management information on behalf of other entities.

1.1.2 Configuration Management

The goal of configuration management is to enable setting up the network devices and their configurations so as to establish the desired operational network topology. It also facilitates monitoring the configuration information so that the effects on network operation of various versions of hardware and software elements can be tracked and managed.

Each network device has a variety of information associated with it. An engineering workstation, for example, may be configured.

Configuration management subsystems store this information in a database for easy access. When a problem occurs, this database can be searched for clues that may help solve the problem.

Refer to Chapter 3, “Configuration Management,” on page 3-1.

WiMax Network Overview


1.1.3 Performance Management

The goal of performance management is to measure and make available various aspects of network performance so that internetwork performance can be maintained at an acceptable level. Examples of performance variables that might be provided include network throughput, user response times, and line utilization.

Performance management involves three main steps. First, performance data is gathered on variables of interest to network administrators. Second, the data is analyzed to determine normal (baseline) levels. Finally, appropriate performance thresholds are determined for each important variable so that exceeding these thresholds indicates a network problem worthy of attention.

Management entities within EMS continually monitor performance variables.

Each of the steps just described is part of the process to set up a reactive system. When performance becomes unacceptable because of an exceeded user-defined threshold, the system reacts by sending a message.

Refer to Chapter 6, “Performance Management,” on page 6-1.

1.1.4 Fault Management

The goal of fault management is to detect, log, notify users of, and (to the extent possible) automatically fix network problems to keep the network running effectively. Because faults can cause downtime or unacceptable network degradation, fault management is perhaps the most crucial component.

Fault management involves first determining symptoms and isolating the problem. Then the problem is fixed and the solution is tested on all-important subsystems. Finally, the detection and resolution of the problem is recorded.

Refer to Chapter 7, “Fault Management,” on page 7-1.

1.1.5 Security Management

The goal of security management is to control access to network resources according to local guidelines so that the network cannot be sabotaged (intentionally or unintentionally) and sensitive information cannot be accessed by those without appropriate authorization. A security management subsystem, for example, can monitor users logging on to a network resource and can refuse access to those who enter inappropriate access codes.

Security management subsystems work by partitioning network resources into authorized and unauthorized areas. For some users, access to any network resource is inappropriate, mostly because such users are usually company outsiders. For other (internal) network users, access to information originating from a particular department is inappropriate. Access to Human Resource files, for example, is inappropriate for most users outside the Human Resources department.

Security management subsystems perform several functions. They identify sensitive network resources (including systems, files, and other entities) and determine mappings between sensitive network resources and user sets. They also monitor access points to sensitive network resources and log inappropriate access to sensitive network resources.


Element Management System

1.1.6 Administration

The Administration tool provides access to runtime administration, security administration and image management capabilities. Refer to Chapter 8, “Administration,” on page 8-1.

1.1.7 Benefits• Centralized Element Management Platform

To achieve greater business successes, networks must adapt well with ever-evolving applications and business environment. Stability and top service quality are the fundamental for daily business operation. As network size grows, it can be a challenge to maintain the network and react to possible network failures promptly. Especially when the network is large and geographically distributed.

To simplify network management, EMS (Element Management System) provides a centralized management platform that allows administrators and network operators to easily maintain and monitor each WiMax network and gateway from a single computer. This allows effective network management.

• Intuitive Hassle-free Operation Interface

With intuitive and user-friendly graphical user interface (GUI), EMS polls network element status and presents the graphical topology in the WiMax Topology Map Viewer. Furthermore, double-click an icon to see the front panel graphical view and get real-time element status updates.

• Network Health Monitoring and Management

It is vital to monitor network traffic to be aware of any abnormal activity. The EMS allows you to monitor network traffic and generate graphical report down to the port level.

In addition, event and alarm management tools can capture SNMP traps and the occurrences and the relevant details as events and in generate alarms as needed.

Event logs are displayed in different colors to indicate the event severity level (Minor, Major or Critical). Actions can be triggered by trap automatically without manual initiation; thus leaves flexibility and convenience to network managers.

• Complete Screen-Based Element Management

With EMS, network maintenance is just a few simple mouse clicks away. Multi-site network operation and maintenance become easier than ever before. You can remotely perform general device maintenance (such as firmware upgrade and configuration file backup/restore) on more than one device on the network. With complete system management features, efficient device monitoring and configuration allow for better network quality and can be cost-effective.

• Strict Secure Access Management

Tight access control is essential for a secure network. In the EMS, access to configuration screens and/or status screens are strictly based on user name, password, user's computer IP address and user account category. The three user categories give login accounts different administration authority. The EMS allows up to 10 users to log in at a time. Information such as the user ID, user group, IP address, configuration actions and time is logged for security reasons. So network managers know who logged in, and what time.

2.4.1.5 Tree

The Tree present on the left-side of the Application displays set of hierarchical data (refer to Figure 2-4). The fundamental object in a tree is called a node, which represents a data item in the given hierarchical set. Thus, a tree is composed of one or more nodes. The root node is the top node of the hierarchical data. Nodes inside the root nodes are called child nodes. By choosing a particular node, the corresponding panel is displayed on the right-side display panel.

2.4.1.6 Alarm Summary View

The Alarm Summary View panel shows the alarm count of each Alarm group. Within each group, alarms of appropriate severity are shown. The Alarm Summary View panel is located below the Application tree (see Figure 2-4). On clicking the count displayed in the Alarm Summary View panel, the alarms of specific severity for that alarm group are displayed in the corresponding Alarm panel. This panel is updated automatically and the counts can be seen all the time, irrespective of the functional view, be it maps or events that are chosen.

2.4.1.7 Performance Summary View

The Performance Summary View panel shows the performance of each Gateway. The Performance Summary View panel is located just below the Alarm Summary View (see Figure 2-4). Running the mouse arrow over the performance summary area will display a Tool tip with a brief description of specific Gateway criteria.

2.4.1.8 Status Bar

The Status Bar is present at the bottom of the screen (see Figure 2-4). It indicates the status of the ongoing process, i.e., it displays Done if all the data is loaded and displays loading... if the process is still going on. The transformation of the color of the status bar from dark blue to green takes place while loading the Application Client.

2.4.1.9 Display Panel

The display panel is displayed on the right-side of Application Client and appears as a window within the main window (see Figure 2-4). This panel is shown when a tree node is selected. For example, if you click Fault Management > Network Events on the tree, the Network Events display panel is displayed on the right-side.

• Viewing a Range of Table Details

• Sorting Table Details

• Rearranging and Resizing Columns in a Table

• Viewing Row Details



2.4.3.1 Navigating through the Table

This section explains the ways in which you can navigate through the table.

The four navigator buttons, First Page, Previous Page, Next Page, and Last Page are located at the top of each table. The purpose of these buttons is detailed in Table 2-3.

2.4.3.2 Setting the Page Length for a Table

To display only a certain number of rows per page, select the value from the Page Length drop-down box.

2.4.3.3 Refreshing the Page View

To refresh the page view, perform the following procedures.

1. Click the right mouse button on a row and click Refresh or

2. From View menu, choose Refresh or

3. Press F5.

2.4.3.4 Viewing a Range of Table Details

To view a range of details, perform the following:

1. Enter the starting range number in the Displaying field.

2. Enter the ending range number in the to field.

3. Press Enter.

2.4.3.5 Sorting Table Details

You can sort the data in a table based on the column type and the details can be viewed either in ascending or descending order. The type of sorting (ascending or descending) is indicated by arrows.

A simple click on the column header does the sorting, i.e., the complete data will be sorted. Subsequent click on the same header sorts the data in ascending order (if it were sorted in descending before).

There are two types of sorting.

• Server-side sorting: Server-side sorting sorts all data in the EMS Server and is not restricted to the data available in the Application Client. For example, if there are 100 events in the EMS Server and only 50 are

Table 2-3 EMS Navigation Buttons

Button Purpose

First Page To view the first page of the window that displays the data retrieved from the database.

Previous Page To view the previously viewed page of the window that displays the data retrieved from the database.

Next Page To view the next page of the window frame that displays the data retrieved from the database.

Last Page To view the last page of the window that displays the data retrieved from the database.



displayed in the Page View of the table, a server-side sorting sorts the complete set of 100 events and not just the 50 events. For server-side sorting, click the column header. Subsequent click on the same column header sorts the data in ascending order (if it were sorted in descending before). The sort indicators for server-side sorting for ascending and descending are up arrow and, down arrow respectively.

• Client-side sorting: Client-side sorting sorts data displayed only in the Application Client. For example, if there are 50 alarms in the EMS Server and only 25 are displayed in the Page View of the table (25 per page), a client-side sorting sorts only 25 alarms and not the 50 alarms in the EMS Server. For client-side sorting, press the Ctrl button and click the column header. Subsequent click on the same header sorts the data in ascending order (if it were sorted in descending before). The sort indicator for client-side sorting for ascending and descending are up arrow and, down arrow respectively.

2.4.3.6 Rearranging and Resizing Columns in a Table

For easy view of the data, rearrange the columns by just dragging the column header and moving it to the required place in the table. This will be helpful to view a couple of data at closer position.

To resize the column header, simply drag the right-side edge of a column.

On performing the rearrangement and resizing, the table remains the same only until the Application Client is open. When reopened, the settings would be lost. To retain the same size of columns, save the style by choosing Custom Views > Save Custom View State menu or click the right mouse button on the node in tree and choose Custom Views > Save Custom View State or press Ctrl+S. Note that on saving the custom view the resizing will only be saved and the rearrangement will not get saved, and the custom view will be displayed in the default order.

2.4.3.7 Viewing Row Details

To view details or object properties of each row in a table, perform the following procedures:

1. Double-click a row.

2. Click the right mouse button on a row and click Details or

3. Press Alt+D keys simultaneously.

A dialog box is displayed with specific details about the selected row.



2.4.4 Broadcast a Message

The option Broadcast Message can be used to send messages to all the clients connected to the EMS Server.

To broadcast a message, perform the following:

1. In the Application, from the File menu, choose Broadcast Message or

2. Press Ctrl+G keys simultaneously. The Broadcast Message dialog box is displayed as shown in Figure 2-7.

Figure 2-7 Broadcast a Message

3. Type the message to be broadcast in the Message field.

4. If Send to my FE client only is selected, the message is sent to all the clients connected to that particular Server. If Send to all client is selected, the message is sent to all the clients connected to different FE Servers, which, in turn, are managed by the main EMS Server.

5. Click BroadCast.

The message is delivered to intended clients that are connected to the EMS Server and is displayed on the status bar.

Configuration Management

3.1 Overview

To setup a WiMax network, complete these common configuration tasks in order. After performing theses tasks you can navigate through the rest of the EMS application to manage the network and to view summary information, and statistics.

You will learn how to:

1. Add Core Services Network (CSN).

2. Add Access Service Network (ASN).

3. Add Basestation(s) in ASN.

4. Add Neighbor Basestations.

5. Add Paging Group(s).

Before You Begin


3.2 Before You Begin

Ensure that the EMS application is running. Make sure that at least one ASNGW has been boot-strapped and is reachable from the EMS server.

For information about installing the software, refer to the Element Management System (EMS) Installation Guide.



3.3 Create a Core Service Network (CSN)

Core Service Network (CSN), is a concept in the mobile WiMax network. It is at the core of the WiMax network architecture providing control and management for the Access Service Network (ASN) and subscribers with services such as DHCP server, AAA, FTP, inter-operator and inter-technology roaming, services and other applications. The CSN also includes the Internet Protocol Multimedia Subsystem (IMS) services support capable of offering Internet access, location-based services, Internet Multimedia and Multimedia Broadcast/Multicast MBS services and voice services.

3.3.1 Create a Top-Level Group - CSN

The CSN can be created or modified using the Configured CSN(s) window.

To create a CSN top-level group, perform the following:

1. In the EMS application, click Configuration > CSN node on the tree.

2. The CSN is displayed as shown in Figure 3-1 below.

Figure 3-1 Creating a Core Services Network (CSN)

This screen is divided into two parts. The top portion of the screen is related to configuring CSN(s). The bottom portion is for configuring Servers related to the configured CSN.

Create a Core Service Network (CSN)


3. Click the Add button. The Add CSN dialog screen will display as shown in Figure 3-2.

Figure 3-2 Adding a CSN

Enter values for the Configuring CSN. For information on each of the fields, refer to Table 3-1.

4. Enter the CSN information; the CSN Name, and Network Service Provider (NSP) Name. These are mandatory fields, as indicated by the "*". Click OK.

A message will appear indicating that the CSN was added successfully. You can add as many CSN(s) that are associated with your environment.

5. Once you are finished entering the CSN(s), the CSN configuration screen will re-display with a list of CSN(s) that you added.

6. Next, you will add a AAA Server for each of the CSN(s) that where created.

Table 3-1 Add CSN

Field Description

CSN Name This is a name given to the Core Service Network. This name will uniquely identify this group of service within this CSN.

NSP Name This is the Network Service Provider name.



3.4 AAA Server

AAA server is a service that handles requests for access to resources and provides authentication, authorization, and accounting (AAA) services. A AAA server is normally identified by a Fully Qualified Domain Name (FQDN) or by an IP address of the computer system that hosts that service.

The AAA server typically interacts with network access and gateway servers and with databases and directories containing user information. The current standard by which devices or applications communicate with a AAA server is the Remote Authentication Dial-In User Service (RADIUS). When a AAA server is configured within EMS, the details are maintained and then forwarded to the ASNGW so that the authenticator within the ASNGW(s) can use the services provided by the AAA server. The EMS does not directly configure the AAA server.

When a subscriber wants to enter the network, and must be authenticated against a AAA server that provides services for the domain from the which subscriber is entering the network. For example, [email protected], must be authenticated against a AAA server that can authenticate users in the domain city.sanjose.com

A AAA server can provide services to one, multiple or all domains.

For any given CSN there can be multiple AAA servers configured. Each AAA server could provide services to one or more domains.

At most, one AAA server can be configured to provide services to one domain and one server to act as the default server that will provide services to all domains. This default server will be used when no other server supports that domain.

3.4.1 Add a AAA Server to a CSN

Begin this procedure from the open Configured CSN(s) screen.

To add a AAA Server to a CSN(s), perform the following:

1. Select Configuration Management > CSN from the configuration tree. The CSN dialog box will display.

2. To configure a AAA Server, first select the CSN that will host the AAA service. When a CSN is selected in the top table - the set of AAA servers associated with that CSN are shown in the dialog at the bottom panel.

3. Select the Add button under the Servers configured for CSN directly from the bottom portion of the CSN screen.

4. The Add AAA Server dialog box will display as shown in Figure 3-3.

AAA Server


Figure 3-3 Adding a AAA Server to a CSN

Add domains (Separated by semicolon)

Manually type in the domain names that this AAA server provides services for separated by a semicolon.

Configured domain(s) This will display all the configured domain(s) for this CSN.



3.5 Creating Access Service Network (ASN)

The ASN Gateway is a high capacity platform with linear scaling properties and the flexibility to meet the needs of small and large networks. Each ASN Gateway can concentrate traffic from hundreds to thousands of radio base stations, which reduces the required number of devices under management and AAA transactions while minimizing connection setup latency by decreasing the number of call hand-offs in the network.

The Access Service Network (ASN) sets and defines the network functions for providing WiMAX subscribers with wireless access. The ASN is comprised of network elements (such as one or more BS and ASNGW) and provides the following functions:

• Layer 2 connectivity with MS/SS

• Transfers AAA messages (Authentication, Authorization, Accounting) to WiMAX subscribers’ Home Network Service Providers (H-NSP)

• Detection and selection of NSP networks chosen by WiMAX subscribers

• Relay functions for building MS/SS and Layer 3 connectivity

• Wireless resource management

• ASN anchored mobility

• CSN anchored mobility

• Paging

Within the EMS application, ASN(s) represent ASNGW and the set of BS(s) managed by that ASNGW. You view gateways as part of your network's hierarchy. In this section, you will add ASN to the CSN group and set basic identification parameters.

Note:Before you begin, you will need a valid IP address for an ASN on your network.

4.2.13 Updating Status

By default, the EMS checks and monitors a device's existence and health in the network and displays its currents status in the Application. Therefore, the status of a device or the network itself is updated on a regular interval. You can also update the status manually.

For example, if the EMS gets (or polls for) the status of a router every 300 seconds, during the process, if you want to know the latest status of that router without waiting until the polling to occur, you can simply update its status manually. This retrieves the latest status of the router and makes it available to the map and database.

To update the status of a device, perform the following:

1. Open the device map.

Chapter 6 Performance Management

This chapter describes how to setup and retrieve performance management statistics and determine the degree to which the network is meeting assigned service levels.


• Overview

• Performance Manager

• ASNGW Metrics

• JVM Monitoring Details


Performance Management

6.1 Overview

An important element of network management is the ability to receive performance information on a large network of many devices to provide an overall view of the user domain. You can then pro-actively manage your network elements by analyzing the performance data.

The EMS provides the capability to monitor the performance statistics gathered from network elements managed by the EMS system. You can set up the Performance Manager to monitor particular attributes or parameters according to their network requirements.

The Performance Management system is a powerful, flexible tool able to view general and performance specific attributes in one application and in a variety of formats (for example, plotting graphs, tables, report generation, etc.). You define the attributes or parameters, choose the objects you want to view, select the date and time of the view, and set the summary interval.

The Performance statistics provides a summary view of the performance of network elements. These statistics help determine the degree to which the network is meeting assigned service levels. From the network to the chassis level.

A selected object or group of objects has a number of different attributes. You can choose to view the performance data for an area of the network, for example, the performance statistics of a particular attribute. This information could then be used to evaluate the performance of the vendor's equipment and access the requirements for upgrades or software downloads.

Performance statistics also provides a summary view of the performance of network elements. These statistics help you determine the degree to which the network is meeting assigned service levels. You are able to drive down to the chassis level from the network level in a simple manner if you want to view individual chassis statistics.

A Performance Manager can be opened for each network element you wish to monitor. To view up-to-date information on the Performance Manager, choose Refresh and the selected data is displayed.

Performance Manager


6.2 Performance Manager

The EMS monitors the performance of your network periodically by collecting necessary data from each of the devices and by providing reports on the same. The performance is measured based on various factors, such as number of bytes of data received/sent (over a period) by a particular interface of a device, the interface's current bandwidth in bits per second, etc.

After discovery, EMS begins to collect data at an interval of 5 to 15 minutes. The collection interval is based on a number of parameters internally determined as part of EMS i.e. user does not have control over it. The data collected from a device in the network is termed Performance Data.

There are two types of performance data that you can view in the Application - Current Performance Data and Historical Performance Data. This performance data can be viewed using Graphs and Reports.


• ASNGW Metrics



6.3 ASNGW Metrics

The ASNGW Metrics option is to present the summarized version of the performance data from the selected devices in a predefined interval and stores it in the database. You can view this data through graphs or tables.

Current performance statistics summary data is automatically updated once every 5 minutes.

You can view current performance statistics data in graphs or in a table view, by performing the following:

1. To view the performance summary statistics data, select an active gateway that is listed to the left of the ASNGW Metrics window and click the mouse button.

2. The active Gateway metrics information will display within the Performance Summary showing five (5) separate graphical boxes as shown in Figure 6-1 below.

6.4 JVM Monitoring Details

EMS JVM Monitoring consists of three units: Monitoring, Management and Maintenance

• Monitoring enables EMS to monitor the memory usage and thread count of the system.

• Management involves taking actions such as sending email notification, dumping thread details and invoking the garbage collector in case of abnormality.

• As part of effective Maintenance, EMS is integrated with third-party software.

6.4.1 Monitoring and Management

Monitoring of JVM parameters such as Memory Usage and Thread count is an important process using which of the JVM performance can be improved and problems such as JVM crash could be prevented.

EMS uses the SNMP mode to store historic information about the EMS JVM parameters so that administrators can monitor the condition of the EMS JVM memory usage at any point of time.

6.4.1.1 BE Server

The process defined in EMS takes care of the following functions:

• Monitors memory usage of the BE Server.

• Monitors JVM resource usage of the BE Server periodically.

• Monitors JVM resource usage of the FE Server JVM periodically. The BE Server starts monitoring the FE server JVM as and when a FE gets connected to the BE.

• Triggers email notification when memory usage of BE or Client exceeds the configured threshold limit.

Table 6-1 BE Server Arguments

Chapter 7 Fault Management

This chapter describes how the EMS provides advanced fault management capabilities for proactive monitoring of network reliability and availability. The detection of fault is a process that gives indication of malfunctioning. Fault detection and notification are two functional areas which should identify problems and effectively inform the system administrator. The EMS offers simple integration of events from diverse servers, and provides ways to process, correlate, and present alarms and events based on domain-specific requirements.

Fault management capabilities include:

• Network Event/trap processing

• Color-coded alarm severity views

• Alarm drill down categorized by severity, managed resource type, time of day, and alarm messaging

• Fault remedy work flow management – Categorize alarms


• Overview

• Network Events

• Viewing Network Events

• Alarm Management


Fault Management

7.1 Overview

The EMS includes an advanced, integrated fault management solution, with real-time site and network element alarm summaries, as well as effective detailed alarm/event viewing and tracking capabilities. Fault management is provided via a full set of alarm monitoring tools. Convenient color-coded alarm banners are provided for individual severity classes. Threshold parameters are used for proactive network management with trigger actions. Alarm correlation tools are available to assist with fault investigations and analysis.

Alarm summary views track and count alarms by site and severity. This allows managers and executive team members, who routinely need to see network status at a glance. The EMS also consists of alarm summary views that offer technicians an avenue to navigate quickly to the most severe problems in the network. The detailed alarm/event browser provides full visibility to all alarm and event attributes and includes interactive features such as alarm acknowledgement, audible alarms, event history, event notes, and viewing the configuration and status of alarmed resources.

EMS users can easily apply any of the built-in alarm/event filters and event browser layouts to create their own personal view. The EMS also allows users to define their own alarm/event filters. These features foster flexible partitioning of work, based on product type, technology, skill level, or geographic domain, as well as a high degree of personal productivity. Users can attach notes to an event or alarm, which helps to track progress toward problem resolution. Notes and acknowledgements are immediately tagged by user ID and time stamp and made available for viewing by all users in the active events/alarms browser. They are also stored in the event history database for future reference.

Network Events


7.2 Network Events

The Network Events application opens from the EMS and allows viewing the status of these groups. Users can add, modify, and delete event parsers, and setup custom event filters.

Event groups can be any combination of objects derived from the EMS managed object class. These groups are set up using queries which can be configured to match your requirements. For example, you could choose to monitor a particular device, specify a date and time period, and choose to look at events which have severity level of warning or critical. You define a query so that the network event only includes the events which meet the criteria you define.

As soon as the group is created it starts monitoring against the criteria specified in the event query setup. Event groups created in the Event Groups application are persistent, they are not cleared when the application is closed.

The Network Events application also enables you to view the events associated with an event group in a scoreboard format. This displays the overall status of the event group as a pie chart, with the associated severity color coding. A scoreboard also shows the total number of events which have entered the event group and the highest severity of the events in the group. An icon is displayed when a running notification has been set up for the event group.

The Network Events enables you to sort the events reported by the system according to event severity, event time, event message and element. In addition, events can be filtered according to time period and severity level.

The Events displays the following information:

• Event severity level (Critical, Major, Minor, Warning, and Clear).

• Date and time of the event.

• Text message describing the event.

You can view all alarms generated by the EMS application by using the EMS Network Events. The EMS Network Events allows you to view all events generated by EMS.

You can complete the following procedures when viewing Network Events:

• Viewing Network Events

• Viewing Event Details

• Viewing Related Alarms

Fault Management

7.3 Alarm Management

Events are correlated into alarms. They represent the current status of the various problems in the network. An Alarm Filter executes certain corrective actions whenever alarms are received with configurable matching criteria, such as suppressing multiple alerts in a given interval, running shell commands on the server system, sending e-mails, sending traps, and executing custom code to filter alerts (see Table 7-2).

Custom code may be needed in cases where any additional data has to be retrieved, or specific rules are to be applied in processing the alarm. Custom code is also the appropriate mechanism to configure alarm grouping, because it usually requires user or domain-specific rules.

The processed alarms are stored in the database and made available in the Alarms Viewer. The Alarm Viewer is asynchronously notified, as soon as the processing of an alert is finished.

You can configure an Alarm Filter using the Alert Filter Configuration. You can use the properties of the alert object in some of the fields, such as to Suppress Action, Run Command Action, Send Trap Action, and Send E-mail Action.

A custom Filter can be configured to enable more effective event correlation and fault management by adding application-specific rules when processing events and alarms. However, this should be done by a developer and not by an administrator.

7.3.1 Alarm Operations

Alarms are generated when a failure or fault is detected in the network devices. The events generated are converted to alarms based on its significance and they are simply messages calling for operator's/administrator's attention.

The administrative tasks that you can perform are:

• Viewing Alarms

• Sorting Alarms

• Searching Alarms

• Printing Alarms

Chapter 8 Administration

This chapter describes how to manage system security for the Element Management System (EMS).


• Overview

• Runtime Administration

• Security Administration

• Image Management


Administration

8.1 Overview

The EMS application provides administrative tools and security features for users and groups. Currently, the EMS application does not provide security directly for elements, but it does provide security indirectly to devices as members of groups.

The EMS application lets an administrator provide security for the network by:

• Determining how users are authenticated, either locally or through a server

• Assigning passwords and privilege levels to users

• Choosing a remote login method for users

• Creating access lists for groups

Runtime Administration


8.2 Runtime Administration

The Runtime Administration helps the System Administrator with various modules of the EMS at runtime. Making configurations at runtime using this tool avoids the hassles of restarting the EMS application every time a configuration is made.

To open the Runtime Administration, perform the following:

1. Open the EMS application.

2. From the Tools menu, choose Runtime Administration or

3. Press Alt+R keys simultaneously. The Runtime Administration screen is displayed as shown in Figure 8-1 below.

4. Choose the required module's tool from the Categories drop-down box or tree.

Figure 8-1 Runtime Administration

The various Runtime Administrative categories include the following:

• Configuring Log Settings


Administration

8.2.1 Configuring Log Settings

The Logging Service comes in handy for various purposes, such as pinpointing bugs, configuration errors, performance blockades, creating audit logs, and tracking various actions in the server.

All messages are stored in log files in the form of Text files (.txt).

You can configure the logging by editing the logging_parameters.conf file using the Runtime Administration tool. Using this tool updates the file at runtime and therefore you do not have to restart the EMS Server after configuration. But if you have edited the file directly through an editor, ensure to restart the Server.

The Runtime Administration Tool can be used to configure the Server-related log messages only. To configure Client-related logs, manually configure the logging_paramenters.conf file.

The following topics will be covered in this section:

• Opening Log File Configuration Tool

• Adding Log Files

• Viewing Details of Log Files

• Modifying Log Files

8.2.1.1 Opening Log File Configuration Tool

To open the Log File Configuration tool, perform the following:

1. In the EMS, from Tools menu, click Runtime Administration or

2. Press Alt+R keys simultaneously. The Runtime Administration tool is displayed.

3. From Categories drop-down box or tree, choose Miscellaneous > Log Settings. The Logging Configuration screen is displayed as shown in Figure 8-2 below. The table lists the existing log file names, the directory where it is located, maximum lines that the file can hold, and the file count.



Figure 8-2 Logging Configuration

8.2.1.2 Adding Log Files

To add a new log file, perform the following:

1. In the Log File Configuration tool, click Add. The Logging Configuration dialog box is displayed as shown in Figure 8-3 below.

Figure 8-3 Adding Log Settings Information


Administration

2. Specify the name of the log file in the Log File Name field.

Only the file names that are compatible with an OS are supported. | Specify extension as .txt | Avoid numbers.

3. Specify the directory where the log file has to be stored in the Logging Directory field.

4. Specify the number of lines to be written in the log file in the Maximum Number of Lines Per File field. This is an optional field. When no value is specified, the default value of 10000 lines is set.

5. When the log file exceeds the maximum number of lines specified, it is carried forward to another new file that is created with similar name. For example, when newfile.txt reaches 10000 lines, then a new file newfile1.txt is created and the logging continues. The number of files that can be created in such cases can be specified in the Maximum Number of Files field. This is an optional field. When no value is specified, the default value of 10 is set.

6. You can configure the maximum number of lines to be kept in memory before writing them to a log file by specifying the value in the Maximum Lines Cached field. For example, if the value is set as 50, the first 50 lines are kept or cached in memory. On reaching the 50th line, all the 50 lines are written to the log file. Then, the second round of writing would happen after caching 50 more lines and so on. This parameter avoids the overhead of frequent writings into the log file for each line.

7. If you require the time stamp along with the log messages, select the Use Time Stamp? field.

8. Click Next. The second Add Log File screen will display as shown in Figure 8-4 below.

Figure 8-4 Add Log Settings Information (continued)

9. Specify the unique key name in the Key Name field. This serves as the key with which EMS differentiates between modules to log module-specific log messages and to identify the type of message, i.e. output or error message.

10. Specify the module-specific name that is to be prefixed with the log message in the log file in the Display Name field.



11. Click Add.

12. Choose the log level from the Log Level drop-down box. If you choose to record the messages belonging to certain level, the messages with levels lower than and equal to the level chosen will be recorded. For example, if you choose Intermediate, then all the log messages belonging to the Summary and Intermediate will be recorded.

– Summary: Important messages

– Intermediate Messages: Frequently generated log messages

– Verbose: Detailed/Error messages

– Debug: Composite of above levels and more information for debugging purposes

13. To enable the logging in this new log file, select the Enable Logging? field. If the log file is created with this option not selected, then the log file will be created in the configured directory, but the logging will not take place.

14. Click Finish.

15. Click Apply to effect changes on the server-side logging_parameters.conf file. The success or failure of writing to server-side file is displayed in the Runtime Administration tool status bar.

The EMS Security Administration option allows system administrators to set up security levels, operations, and audit trails for individual Groups and Users. Individual Groups and/or Users are given specific privileges that are set up by the administrator.

The access level is set up to allow or restrict user access to features within EMS. For example, an administrator could set up a user to have access only to those parts of EMS which are relevant to their specific tasks. A user would only be aware of their own access to the system and the use of their password.

The following Security Administration tasks are explained in this section:

• Security Levels

• Adding Users

• Changing User Profile

• Assigning Groups to Users

• Changing User Password

• Managing Audit Trails

• Deleting Users

• Managing Operations

8.3.1 Security Levels

EMS Security also enables administrators to define security levels for specific managed object attributes. This is key to restricting access to sensitive or critical parameters of managed equipment. A user with access may be able to apply a new configuration to that piece of equipment, but they may not be able to modify its IP address, as this could invalidate normal management of the device. Control of the IP address may be the specific responsibility of the network topology manager.

8.3.1.1 User Access Levels

There are two types of user access (Permission) levels available. They are:

• Excluded (basic level)—useful for a new user finding their way around the EMS system. The system administrator can set up the permissions tree hiearchy for users who have limited access.

• Included (administration level)—used by an administrator who can access all features at all times. The system administrator can set up the permissions tree hiearchy for administrative level user capabilities.

Security Administration


8.3.2 Adding Users

You can add a user whenever you need to provide access to the EMS Client. By default, the new user has login permission only. You provide access to various modules by making the user a member of pre-configured groups or by directly assigning permissions to the user.

You can add a new user, perform the following:

1. In the Application Client, select Tools menu, choose Security Administration or

2. Press Alt+S keys simultaneously. The Security Administration window is displayed as shown in Figure 8-8 below.

3. In Security Administration window, select File menu, choose New > AddUser or

4. Press Ctrl+Shift+U keys simultaneously.

5. Click AddUser or

6. Click the right mouse button on the Users node within the Security tree (located at the left side of Security Administration window) and click AddUser.

Figure 8-8 Security Administration

7. The User Administration window is displayed as shown in Figure 8-9 below.


Administration

Figure 8-9 User Administration

8. Type the user name and password in appropriate fields and click Next. If no password is specified, the user name is set as the password.

9. Click Next. The User account expiry and Password expiry screen displays as shown in Figure 8-10.

Figure 8-10 User Account and Password Expiry

10. Complete one of the following steps:

By default, the user account never expires.

• If you are providing access for a limited number of days, type the number of days in which the account expires in the Day(s) field.

• If the account has no expiration, check the Account never expires check box.



In the User Account and Password expiry section, complete one of the following steps:

By default, the user account never expires.

• If the password has an expiration time period, type the number of days in which the password expires in the Day(s) field.

• If the password has no expiration, check the Password never expires check box.

Here user account expires and password expires are two different entities. You can give user name and password expiry separately. Password expiry is checked only when the user tries to login. Whereas the user account expiry check is done at a regular time interval. This time interval check works only if time_interval_for_security_scheduler_in_ms parameter in NmsProcessesBE.conf file is configured (in milliseconds). By default, the value is set as '0' whereby scheduler will not be started and the user expiration check will not be done.

Click Next.

11. If you are associating the user with an existing group, complete the following (see Figure 8-11):

• Check the Group based permissions check box to enter a new group name in the dialog box. Click Add Group.

• Check the Direct assignment check box to assign permissions directly from the Permissions Tree.

• In Assign groups for the user, click on the check boxes next to the groups to which you want to assign groups for the user. Select either User or Admin.

Element Management System (EMS) User’s Guide WiChorus Confidential A-1

Appendix A Glossary

Alarm

Alarm results from correlation of events and represents failure or fault in a network element that may need immediate attention.

Container

This is the interface for grouping together and managing a set of managed objects, using the containment relationship model.

Link

A link is a diagrammatical representation of the connection between two symbols.

Managed Object

A Managed object holds information about a network entity. The network entity can be a network device, such as computer, printer, router or a component of the device like port, card, slot, interface etc.

Map Symbol

Diagrammatical representation of objects in a map are called Map Symbols. For example, a Gateway Map depicts gateways as images which are called the Map Symbol.

Network Events

Event is the basic unit of management information that is complete in itself and relates to an occurrence, such as discovery of an element, status update of an element or failure in an element. Events form a repository of information for all the occurrences in the system.

Object

Refer to Managed Object.

Polled Data

Basic object used for data collection. It contains the details such as which device has to be contacted, what data needs to be collected, in what time interval etc. This does not store the collected data. Poll engine reads PolledData definition and according collects data from the network device. Also termed Statistics.

A-2 WiChorus Confidential Element Management System (EMS) User’s Guide

Polling

Process of contacting the device agent and collecting the data for the specified OID. PolledData will contain the OID details.

Statistics

Also termed Polled Data.

Status Polling

Process of pinging the device and determining its state such as up/down at regular intervals. If Status Polling yields negative results, i.e. if the device is not responding, provisions are made to report the condition, which requires attention.

Threshold

It is a value that determines the minimum and maximum limit for the collected data. If the collected data violates the threshold then it indicates some severe fault in the device which requires attention.
