This chapter provides a general overview for using the Cisco Digital Subscriber Line Manager (CDM) graphical user interface (GUI) to manage the Cisco DSLAM chassis and other network components. This chapter also describes how to navigate through the GUI.
This chapter includes the following sections:
CDM supports the following Cisco DSLAM chassis:
Refer to the Cisco publications at the following url for more detailed information about the individual DSLAM hardware:
http://www.cisco.com/univercd/cc/td/doc/product/dsl_prod/index.htm
The Cisco DSL Manager software consists of two applications:
 |
Note For more detailed information about using Cisco EMF software, refer to the Cisco Element Management Framework User Guide. |
You must install Cisco EMF before you can run CDM. Cisco EMF provides the commands, icons, and menus that you use to access the services available in CDM. Using CDM, you can configure the Cisco equipment that you want to manage on your network. Combined, Cisco EMF and CDM provide you with a visual representation of the Cisco DSLAM equipment on your network.
To run CDM, you must start Cisco EMF using the cemf start command. When Cisco EMF launches, CDM automatically starts. When you start a Cisco EMF session using the cemf session command, the Cisco EMF Launchpad window opens. You click the Viewer icon in the Launchpad to open the Map Viewer window where you can access all CDM menus and dialog boxes, or windows.
|
Note All users have access to the tools available in Cisco EMF. Not all users have access to CDM. The system administrator can restrict user access to CDM. When you log in to Cisco EMF, your access to the system is determined by your user name and password. |
This section provides an overview of the CDM software application and includes the following sections:
CDM is an element manager (plug-in module) for Cisco EMF. You can have a variety of element managers plugged into a single Cisco EMF application. For example, from one Cisco EMF application, you can monitor and manage the objects of a Cisco 6015, Cisco 6100, Cisco 6130, Cisco 6160, and Cisco 6260 chassis.
The CDM element manager is designed for network managers who are responsible for performing the following tasks:
From CDM, you can add elements (such as a Cisco DSLAM) and objects (such as NI-2 cards and line cards) to the database. You can modify and delete configuration information and update system software without disrupting traffic on the network. When you modify, delete, or add configuration information in CDM, the system sends the changes to the managed DSLAM.
The Cisco EMF and CDM applications exchange configuration data between the client workstations and the server as follows:
The software stores a system log file (Syslog) and an event log file (EventLog) on the DSLAM that you can view from CDM. These files log all command line interface (CLI) commands that the DSLAM receives and all events that affect the device.
Additionally, CDM keeps an audit log for transactions that users make. This log reports affected attribute, time, date, and value changes. These changes are stored in the /opt/cemf/logs directory as audit files and are stored by CDM.
Each CDM process has a log file that stores process-generated messages. The log files are generally stored in the /opt/cemf/logs directory as .log and .old files. At installation, a system administrator may designate another directory to store these files. Usually, the transaction log file is stored in this same directory.
You can view or print system log information from the SysLog Messages window. The SysLog Messages window contains a list of network components from which you select to view error and status messages. Messages that may display in the SysLog Messages window for a component are alarms or loss of traffic notifications.
You can select a severity range for the events you want to view. The Debug severity level is the least severe type of message generated by the system, and Emergency is the most severe type of message. From the SysLog Messages window, you can select a single severity level for the error and status messages you want to view, or you can select a range of severity levels.
See the "Viewing and Configuring the System Log File" section for more information about the system log file.
Each time you change a component configuration on the network, the system creates an entry in the Command History file. From the Command History window, you can view the details of each configuration entry, including information such as the event, the time the event occurs, the name of the logged-in user, the Internet address of the system that is making the request or the system about which information is being requested, and other information.
See the "Viewing and Configuring the Command Log Window" section for more information about the command history file.
Through CDM, you can query or configure network components. You can manage these components by using a hierarchical structure. For example a site is a top-level hierarchy and contains DSLAMs. DSLAMs are the next level below site and contain cards. Cards are at the next level below DSLAMS and contain interfaces (or ports). Interfaces are at the next level below cards, and contain xDSL profiles and PVCs or SPVCs.
For network management, the state of the components also operate within a hierarchy—The lower level objects inherit the state, the availability of service, and the chassis or card with which they are associated.
For example, if you or the system decommissions a chassis, all cards and interfaces associated with that chassis become unavailable. If you or the system decommissions a card, all interfaces associated with that card become unavailable.
Figure 1-1 shows the hierarchy of the components, as well as how the state of each component affects the availability of its associated component. In this diagram, assume that the chassis and lower level objects are deployed.
To identify the operational state of a selected component, look in the status bar on the bottom left corner of each window. The state of each component directly affects the operations you can perform on that component. By default, the window refreshes every 10 seconds and displays updated states.
The following sections provide a general overview of the states available in CDM:
|
Note For detailed information about element manager and object states, refer to the appendix about map states and icons in the Cisco Element Management Framework User Guide. This appendix provides descriptions of primary states, secondary states that display Open System Interconnection (OSI) icons above managed objects, and non-OSI icons. |
In the Normal state, CDM polls the network to detect the presence of objects. When an object enters the Normal state, CDM polls the object every 60 seconds to determine whether the object is present. An object is placed in the Normal state when you click the Commission button on that object. When you commission an object, you are requesting that the system place that object in the Normal state.
An object that is in the Normal state can be actively managed on the network.
When you start performance logging on an object, the state of that object changes from Normal to Performanceloggingon. The performanceloggingon state indicates that the selected card or interface has performance logging enabled. When you enable performance logging, the system collects performance data on the object. You can view the data in the Performance windows or right-click an object from the list box, and then choose Tools > Performance Manager from the object menu.
When an object is in the Performanceloggingon state, it can be actively managed on the network.
See "Viewing Performance Data," for more information about viewing performance data in the Performance windows.
If an object state is in lostcomms (lost communications) or discoverylostcomms, you are unable to query any of the displayed values. If you click a field in a window for any of the chassis objects when its state is in lostcomms or discoverylostcomms, the information does not display.
When you want to replace an existing card, or perform any kind of maintenance on an object, you should first decommission that object.
When you decommission an object, the following events occur:
Decommission buttons are located in certain windows, depending on the type of object you select. When you decommission a chassis, module, or line card, the system changes the state of all objects that are associated with this object to decommissioned. You must decommission a chassis, module, or line card before you delete it. (See the "Deleting Network Elements" section for this procedure.) You cannot decommission interfaces, for example OC-3 or DS3 types of ports. However, if any object does not physically exist on the DSLAM, but exists in software such as a preprovisioned card, do not decommission it before you delete it from software.
Preprovisioning applies to xDSL line cards only. After you insert a line card into a preprovisioned slot (preprovisioned with the same line coding), the state of the line card moves to a normal state. You do not need to commission this line card.
The autodiscovery process detects any Cisco DSLAMs with either IP or SNMP identifiers. When you activate the autodiscovery function, the system detects a chassis and creates a chassis object. The software places that chassis object below the path that you specify in the Use Physical Path field in the Autodiscovery window. The software also creates a map of the chassis and its associated objects.
Autodiscovery can detect objects on more than one subnetwork by using multihop discovery. You can specify the physical location under which you want the software to create the discovered objects. You can also schedule multihop discovery to run at preset times. (Refer to the Cisco Element Management Framework User Guide for instructions on setting the schedules.)
Autodiscovery detects the presence of devices through the following processes:
Refer to the Cisco Element Management Framework User Guide for detailed information about using autodiscovery.
This section provides an overview of the Cisco EMF Launchpad and includes the following sections:
The Cisco EMF Launchpad, which is shown in Figure 1-2, is the first window that opens after you successfully start a Cisco EMF session. Throughout this guide, the Cisco EMF Launchpad window is referred to as the Launchpad. The Launchpad contains two areas—the CEMF Manager and the Event Manager.
The icons that display in the Cisco EMF Launchpad window represent access to applications that are available with the standard Cisco EMF installation. Additional icons may appear if you install additional applications. Two methods are available from which you can launch an application:
|
Note The first time you access the Launchpad window, your console must be set up to display sufficient colors. Otherwise, you may be unable to launch an application by clicking its icon. If you are unable to open an application by clicking its icon, try moving the Launchpad window to look for a dialog box that is open behind it. The following warning message displays in the dialog box, "There are insufficient colors available for CEMF client. Some applications may not display information correctly." You must click OK in the warning dialog box to launch an application. |
The standard Cisco EMF application icons are shown in Figure 1-2.
The following sections briefly describe the icons that display in the Launchpad. Refer to the Cisco Element Management Framework User Guide for more detailed information about Cisco EMF applications.
The icons in the CEMF Manager area are described in this section.
Click the Viewer icon, which is shown in Figure 1-3, to open the Cisco EMF Map Viewer window, through which you can view, build, and monitor your network by using graphical representations of network elements.
The Viewer icon is the primary entry point into CDM. When you open the Map Viewer window, you can monitor the status of all network elements or abstractions of elements that the network contains, and you can launch any additional applications from the Launchpad.
Click the Groups icon, which is shown in Figure 1-4, to launch the Cisco EMF Object Group Manager window. You can also select Groups from an object menu from other Cisco EMF windows.
You can use the Cisco EMF Object Group Manager, called Groups, to organize network elements into object groups. See the "Creating User Groups" section for how to set up user groups for CDM.
|
Note For more detailed information about this feature, refer to the chapter about the Object Group Manager in the Cisco Element Management Framework User Guide. |
Click the Access icon, which is shown in Figure 1-5, to open the Cisco EMF User Access Control manager window.
The Cisco EMF User Access Control feature allows system administrators to control user access to specific features of their system. Access control is important for security as well as efficient and effective network management. See the "Creating User Groups" section for instructions to customize user access in CDM.
|
Note For more detailed information about this feature, refer to the chapter about User Access Control in the Cisco Element Management Framework User Guide. |
Click the Events icon, which is shown in Figure 1-6, to open a Query Editor window, from which you can specify alarm and event severity for monitoring alarms and events that occur within the system. These events display in the Event Browser window. See "Viewing Alarms and Events," for more information about using the Event Browser window.
In Cisco EMF, when a condition or fault occurs on a managed object in the network, the system receives immediate notification. Being able to identify system events and quickly resolve them is one of the most important aspects of network service management. For example, a power supply fault in a chassis is a critical fault that might require an immediate field service call.
Click the Discovery icon, which is shown in Figure 1-7, to open the Cisco EMF Auto Discovery window. You can click this icon or you can select Discovery from an object menu to begin the autodiscovery process.
The Cisco EMF autodiscovery feature allows you to survey the network for IP and SNMP devices and create a managed object for each new device that it discovers. You can access Auto Discovery from the Cisco EMF Launchpad window or from an object menu.
This section briefly describes the icons that display in the Event Manager area of the Launchpad.
Click the Notify icon, which is shown in Figure 1-8, to launch the notification profile application.
Cisco EMF uses notifications to inform operators of network events that it has monitored. You can set notification profiles to specify how notifications are collected. Refer to the chapter about notification profiles in the Cisco Element Management Framework User Guide for more detailed information.
Click the Thresholds icon, which is shown in Figure 1-9, to launch the thresholding regimes application.
A threshold regime is a set of threshold conditions for specified object attributes which, when breached, causes the software to run one or more notification profiles. Refer to the chapter about thresholding regimes in the Cisco Element Management Framework User Guide for more detailed information.
Click the Event Grps icon, which is shown in Figure 1-10, to launch the event groups application.
You can use the event groups application to organize network elements into event groups and view the status of these groups as scoreboards. Refer to the chapter about event groups in the Cisco Element Management Framework User Guide for more detailed information.
CDM uses the familiar functions and menus that are found in most UNIX-based GUI products. This section describes the functions that are available in CDM and includes the following topics:
Certain keyboard commands are available in CDM. These commands serve as an alternative to mouse functionality. Table 1-1 shows the available keyboard commands and their descriptions.
Cisco EMF and CDM provide right-click mouse functionality. Position the cursor over an object or an event listed in the Event Browser, and then right-click to view the menu options available for that object. This menu is referred to as the object menu throughout this guide. Once you access the object menu, you can use either mouse button to select the option you want.
The menu bar is located at the top of each window, as shown in Figure 1-11.
Click the preferred menu from the menu bar to display the menu choices for that menu. You can also access a menu by entering the appropriate keyboard command. For example, to access the File menu with a keyboard command, simultaneously press the Alt and F keys. Refer to the section about shortcut keys in the "Welcome to Cisco Element Management Framework" chapter of the Cisco Element Management Framework User Guide for a list of keyboard shortcuts.
|
Note The menu choices that display in the Cisco EMF windows and CDM windows menu bar vary depending on the window from which you are viewing or configuring information. In addition, if a menu option is dimmed, the option does not apply to the active window (the window you are currently viewing or configuring). |
The CDM menu bar menus are described in the following sections:
The File menu contains choices for common operations such as Print, Save, and Close.
The Edit menu contains choices for Copy Configuration, Copy Page Configuration, and Paste and Save Configuration. You can copy the configuration from one window and paste it into a different window to minimize duplicate data entry.
The View menu, which is shown in Figure 1-12, is accessible in the Map Viewer window. You can use the View menu to open map views from within a map view, view text descriptions of the object you are viewing, and sort the contents of the object list box by class or name.
The View menu choices are described in Table 1-2.
| 1Cisco EMF automatically creates an object called a shelf when you deploy a DSLAM. The DSLAM becomes an object within a shelf. |
You can use the Options menu, which is shown in Figure 1-13, to update configuration changes manually or to set the system to automatically update all configuration changes. You can also view or hide the toolbar, and enable or disable tooltips from the Options menu.
The Options menu choices are described in Table 1-3.
| Menu Choice | Description |
|---|---|
Set the system to automatically update the contents of the window each time you, or another user, make a change to the configuration. If a checkbox appears to the left of the option, the option is enabled. |
|
Set the system to update the contents of the window only when you select this option. If you want the system to automatically update the contents of the window each time you, or another user, make a change to the configuration, enable the Dynamic Update On option. |
|
Click to acknowledge changes that occur in the window you are viewing or configuring. The default color for text in a window is black. However, if a change occurs to the window you are viewing, the text changes to blue. Often this choice is dimmed, as it appears in Figure 1-13, because no changes have occurred in the window. |
|
View or hide the toolbar. If a checkbox appears to the left of the option, the toolbar is visible. If a checkbox does not appear to the left of the option, the toolbar is not visible. See the "Using the Toolbar" section for more detailed information. |
|
View or hide tooltips. If a checkbox appears to the left of the option, a tooltip appears when you pause the pointer over an item in the window. If a checkbox does not appear to the left of the option, tooltips are disabled. The tooltips feature is enabled by default. When enabled, the tooltips feature displays a brief description of each icon when you place your cursor over the icon for a few seconds. Note The tooltips feature is especially helpful when you are setting subscriber properties and other configuration tasks within the windows in the GUI. As you set the values that are available in a window, the tooltips display the valid and available values for each setting. |
The Window menu lists all of the windows that are open in CDM, with the exception of the active window. You can activate a nonactive window by selecting it from this list.
The Navigation menu choices are limited in this release and are dependent on which window you are in. For example, if you have the Subtend Configuration window open, the Navigation menu choices are Delete Subtend PVC and Add Subtend PVC.
The menu choices in the Actions menu mirror the command buttons that appear in an active window. For example, if the active window displays a Commission and Decommission button, the Actions menu options are Commission and Decommission. Two examples of the Actions menu, the first from the ATM Connections Management window and the second from the Chassis Configuration window, are shown in Figure 1-14.
The Help menu and Icon Information options provide an online guide to Cisco EMF. Please consult the printed manuals available through the Cisco web site for help about CDM.
|
Note The first time you choose the About option, a Netscape license agreement window opens.
Click the Accept button and the About Cisco EMF window opens. By default, Netscape software is automatically downloaded when you install Cisco EMF software. The Cisco EMF/CDM Help system uses Netscape tools such as the search engine. |
This section describes the menus that open when you right-click over an object and includes the following sections:
To access the CDM object menus, place your cursor over a CDM object on the left side of the Map Viewer window, over the chassis view, or over other object icons, then right-click. A single menu or a set of cascading menus open. An example of an object menu is shown in Figure 1-16.
You can also place your cursor over the graphical representation of the object on the right side of the Map Viewer window and right-click, as shown in Figure 1-17.
|
Note In this user guide, instructions are given to access the object menus from the left side of the Map Viewer window. However, you can access these menus in the way that you find most convenient. |
The choices on the object menus reflect the type of object from which you access the menu. Many of the tasks that you perform while using CDM are accessible through these cascading object menus.
Choosing from an object menu opens a new window of that name. For example, if you right-click over a chassis object from the left side of the Map Viewer window, you can choose Deployment > Deploy Cisco DSLAM to open the Deployment Wizard window.
In this user guide, these menus are referred to as the object menu, even though the menu may include a set of several menus. These menus are described in more detail in the following sections.
To deploy a chassis or other object, you must access the Deployment menu, which is shown in Figure 1-18.
The Deployment menu has the following set of choices. The first three are generic to Cisco EMF, and the last three are specific to CDM.
To access map functions in Cisco EMF, you must access the Map menu, which is shown in Figure 1-19.
The following choices are available from the Map menu:
To access Cisco EMF applications other than through the Launchpad, you can use the Tools menu, which is shown in Figure 1-20.
From the Tools menu, you can choose from the following tasks:
The options that display from the View Manipulation menu depend on whether you open it from the chassis level or from the site level.
The View Manipulation window from the chassis level is shown in Figure 1-22.
If you choose Rename Object, the Cisco EMF Rename Object dialog box opens, shown in Figure 1-22. Refer to the Cisco Element Management Framework User Guide for more information about renaming objects.
The View Manipulation menu from the site level is shown in Figure 1-23. Reparenting is not recommended because it may affect the integrity of your system data.
To access most of the windows through which you manage the Cisco DSLAM, you use the Cisco DSL Manager menu. This menu has several sets of menus from which you can choose many functions. The menus that open depend on what type of object you right-click to access the menus, that is, a chassis object, a module, an interface, a PVC, or a profile.
The Chassis Administration menu, which is shown in Figure 1-24, is an example of a Cisco DSL Manager object menu.
See "Using the Cisco DSL Manager Object Menus," for more detailed descriptions of all of the Cisco DSL Manager object menus.
This section describes other navigational tools that you can use to perform tasks in CDM and includes the following topics:
Some windows have several sections that are separated by tabs. An example of tab structure is shown in Figure 1-25.
Tabs separate related information when more information is required than can fit in a single window. Some windows have only one tab, which allows for development of new features in future releases of the software.
The CDM toolbar (see Figure 1-25) is located directly below the menu bar, contains tool icons and provides quick access to CDM commands. You can use the tools in the toolbar to perform common functions such as close, print, save, update, and so forth. Additional tools allow you to access detailed information about a selection in the active window.
The tools that display in the toolbar depend on which window is active. If a tool is dimmed, it is not accessible from the active window. You can also disable the toolbar so that it does not display in the window.
To enable and disable the toolbar, choose Options > Show Toolbar.
To choose a tool from the toolbar, click once on the tool.
For a description of a tool, pause your cursor over the tool in the toolbar. A tooltip appears that describes the use of the tool.
|
Note In many of the CDM GUI windows, you can click the Save icon that is located in the toolbar to save any changes that you make in the window. Throughout this guide, instructions to click Save refer to clicking this Save icon in the toolbar. |
To enter data in text fields, place your cursor in the field and enter the information by using your keyboard. Some text fields also provide a down arrow that you can click to display a set of valid options.
Most windows include a list box, which is shown in Figure 1-25 on the left side of the window. When you select an object in the listbox, it is highlighted. The data about that object displays on the right side of the window, or you can set data for that object on the right side of the window.
Buttons that initiate commands appear in windows from which you can configure or update information. The command buttons that appear depend on the window you are viewing or configuring.
For example, if you want to commission a chassis, select the chassis and navigate to the Chassis Configuration window, which is shown in Figure 1-26. Select the object or objects that you want to commission from the list box, and then click the Commission button.
CDM displays a status bar, which is shown in Figure 1-27, at the bottom of a window. You can view system or network information in real time by reading the information in this status bar. CDM automatically updates the information in the status bar as you modify configuration parameters or send data changes to the node.
Most of the interfaces in the CDM GUI are referred to as windows. However, CDM also contains several dialog boxes that provide information about the success or failure of an action, or that ask you to confirm whether you want to proceed with an action. These dialog boxes include the Action Report dialog box, Prompt dialog box, Error dialog box, Notification dialog box, and so forth.
The Action Report dialog box generally informs you whether CDM successfully completed an action or process. An example of an Action Report dialog box is shown in Figure 1-28.
The Prompt dialog box, which is shown in Figure 1-29, issues prompts from CDM.
The Error dialog box displays error messages. An example of an Error dialog box is shown in Figure 1-30.
The Notification dialog box, which is shown in Figure 1-31, notifies you about certain processes.
Other dialog boxes may open for which you click Yes or No. An example of this type of dialog box is shown in Figure 1-32.
You can navigate through the Cisco EMF and CDM GUI by using graphical images and icons. To view or configure objects on your network, you should use the Physical hierarchy view or the Component Managed view, which are shown in Figure 1-33. The hierarchy views are located on the left side of the Map Viewer window. For more detailed information about the hierarchy views, see the "Using the Map Hierarchy Views" section.
The graphical representation of a specialized module, such as the NI card for the Cisco 6015 OSP DSLAM, displays on the chassis view. See Figure 1-34. See the "Graphical Objects" section for more information about the graphical objects that display on the chassis view.
|
Note For more information about the informational balloons that appear above the line cards in the chassis view, refer to the section about graphical cues in the Cisco Element Management Framework User Guide. |
When you select an object such as a chassis, card, or interface from the cdmManager list, a graphical image of the object displays on the right side of the window. Figure 1-33 shows an example of a Cisco 6160 chassis image after you select the chassis from the hierarchical list on the left side of the window, and Figure 1-33 shows an example of a Cisco 6015 OSP chassis image.
To view or configure objects in CDM, follow these steps:
Step 2 Expand the hierarchy on the left side of the window, as follows, and select a chassis:
To expand the hierarchy, click the "+" next to the managed element name. A graphical image of the chassis displays on the right side of the window when you click the icon for that chassis, as shown in Figure 1-33. You can continue to expand the hierarchy by clicking the "+" next to the object name. You can also right-click an object, such as an NI-2 card or line card, in the chassis image on the right side of the Map Viewer window to display the menu options that are available for the selected object.
Figure 1-35 shows an example of an object menu.
Step 3 Choose an option from the menu to view or configure the object on the network.
Graphical objects display additional icons on top of the existing object icons that the Map Viewer displays. The additional icons provide information such as the state of the object or the event status. See Figure 1-36.
|
Note Events shown visually are the most severe. |
A telecom graphical object represents a network element such as a node, shelf, shelf item, or link. Each object provides graphical cues that supply information about the associated network element of an object. This information can be structural, such as a network element name, or the information can be about states and events, such as out of service.
|
Note For more detailed information about the state and class information that an object displays graphically, refer to the section in Chapter 3 about graphical cues in the Cisco Element Management Framework User Guide. |
This section describes the hierarchical map views and includes the following topics:
The map hierarchy view, on the left side of the Map Viewer window, models the hierarchical relationships between objects, both physical and logical. Objects are organized into different views and can exist in multiple views simultaneously by reference. Each object can have a number of parent and children objects. You can access CDM objects by navigating through one of the views to find the object. Each view represents a different way of containing and grouping objects.
When you open the Map Viewer window, you can monitor the status of all network elements or abstractions of elements that the network contains. The Map Viewer window is divided into two sections. The left side displays objects in a hierarchical map format. The graphical representation of an object that you select on the left displays on the right side of the window.
To resize the hierarchy and map areas, position your cursor over the boundary, and click and drag the boundary. You can view all information on the left and right sides of a window by using the horizontal and vertical scroll bars.
The top level CDM map hierarchy view is shown in Figure 1-37.
The names that display at the top level (see Figure 1-37) are specific to Cisco EMF or to CDM. The standard Cisco EMF views are the Network and Physical views. All other views are specific to the CDM. You can accomplish most CDM-specific tasks by using the Physical or Component Managed view, through which you can look at physical maps of each Cisco DSLAM chassis. You can access the object menus for each managed object by right-clicking an object.
CDM has the following map hierarchy views:
If you also install the CDM NI-1 element manager, the following hierarchy views display above the NI-2 hierarchy views:
The map hierarchy views that are relevant to the Cisco NI-1 DSLAMS are described in the Cisco DSL Manager NI-1 User Guide.
An example of a hierarchy view, the Component Managed hierarchy view, is shown in Figure 1-39.
In the hierarchy views, you see colored circles next to each object. The first circle that displays next to an object represents the highest level of alarm for that object. For example, if there is no alarm on that object, the circle is green for normal (see Table 1-4). The number and second circle that display in parentheses next to the object indicate the number of objects that are managed by that object and the highest severity level of alarms on any of those objects. So, if there is a 13 and a red circle, there are 13 objects associated with this object and there is a critical alarm on at least one of these subordinate objects.
| Color | Severity of Alarms |
|---|---|
The Component Managed hierarchy view is shown in Figure 1-39.
The Component Managed view is a superset of the Physical view (see the "Physical Hierarchy View" section). This view displays PVCs and SPVCs as children of the DSL line interface under which they are created and displays ATM QoS profiles as children of the DSLAM chassis object, as well as the details that display in the Physical view.
The difference between the Physical and Component Managed views is that when you click a chassis object from the Physical view, on the left side of the Map Viewer window, the GUI displays a bitmap representation of that chassis and its line cards on the right side of the Map Viewer window.
The IMA hierarchy view displays IMA links that make up an IMA group on Cisco 6015 and Cisco 6160 DSLAMS. An example of this view is shown in Figure 1-40.
The Network hierarchy view represents the network devices within their respective networks and subnetworks.
The autodiscovery process uses the Network hierarchy view to determine which devices CDM has already added to the system, which prevents autodiscovery from trying to discover the same device multiple times. The Network hierarchy view is a standard view within the Cisco EMF software application.
The Network view displays all IP devices under their parent network. This view provides a logical layout of the network structure. It does not provide topology information. A diagram of the Network view is shown in Figure 1-41.
The Physical hierarchy view, which is shown in Figure 1-42, reflects the physical relationship of objects. From this view, you can drill down to specific interface icons to view the ports that are contained within each module.
The Physical hierarchy view is common to Cisco EMF. Subscriber and pool information does not display from the physical map. Sometimes it is more convenient to work within the Physical view, but that is a matter of personal preference. The Physical view holds location information for all equipment in the network. In this view, relationships are defined based on the physical containment position of each object.
You can click a chassis object from the Physical view on the left side of the Map Viewer window. When you do, the GUI displays, on the right side of the Map Viewer window, a bitmap representation of that chassis and its line cards.
The Subtend hierarchy view, which is shown in Figure 1-43, displays subtended DSLAMs in hierarchical order.
The Subtend View contains each chassis and its network interface ports. After CDM discovers the subtend topology, this view displays the connections between trunk and subtend network interface ports of DSLAMs in a subtended relationship. The trunk port of a subtended (child) DSLAM is connected to the subtend port of a subtending (parent) DSLAM. In this illustration, the DS3-11-1 is the trunk for the IMA groups and IMA links. For more detailed information about these relationships, see "Configuring Subtend Configurations."
The Subtend PVC Hierarchy view, which is shown in Figure 1-44, displays the subtend PVCs that have been created within subtended DSLAMs.
When you first open CDM by clicking the Viewer to open the Map Viewer window, the window that is shown in Figure 1-45, opens.
The Map Viewer window uses graphical representations of network elements, through which you can view, build, and monitor your network. Examples of the Map Viewer window showing the graphical representation of a chassis are shown in Figure 1-46 and Figure 1-47. This is the view that you see after you have deployed the chassis and modules (line cards), and commissioned them. (See "Getting Started Using CDM," for these procedures.)
As CDM deploys and synchronizes a chassis, arrows that point up appear on each module. When the arrows disappear, that is an indication that CDM has deployed and synchronized that module.
Each module on the chassis view is outlined in a color or uses some other graphical notation to help you identify the object state and current alarm status, as follows:

Note Refer to the "Graphical Cues" and the "Informational Icons" sections of the Cisco Element Management Framework User Guide for more detailed information about Cisco EMF graphical cues, including alarm and object status, that you see in the CDM GUI. |
CDM supports a number of alarm sources, including SNMP traps and SNMP alarm tables for Cisco chassis. In addition, CDM posts several different types of events. You can display detailed information about alarms and events in the Event Browser window.
See "Viewing Alarms and Events," for more detailed information about viewing alarms and events.
