This chapter provides an overview for using the Cisco Digital Subscriber Line Manager (CDM) software, which is based on the Cisco Element Manager Framework (Cisco EMF), to configure and manage your Cisco 6100 Series system with a network interface 1 type of card (NI-1). This chapter describes the basic concepts of Cisco EMF and how to use the commands, icons, and menus to access services through the CDM graphical user interface (GUI).
 |
Note For more detailed information about using the Cisco EMF, refer to the Cisco Element Management Framework User Guide. For information about CDM for DSLAM chassis configurations that use a network interface 2 (NI-2) type of card, refer to the Cisco Digital Subscriber Line Manager NI-2 User Guide. |
This chapter includes the following sections:
CDM is a scalable, multiprotocol management software. You can use CDM to configure system networks that are based on Cisco IOS and that manage digital subscriber line access multiplexers (DSLAMs). This version of CDM is capable of managing Cisco 6100 and Cisco 6130 DSLAM chassis that have an NI-1 type of network interface module. You can use CDM to provision connections, detect faults, configure devices, and track network statistics.
You can accomplish the following tasks using CDM:
CDM offers the following benefits:
CDM with NI-1 supports the Cisco 6100/6130 Series system chassis. CDM NI-1 version 3.4 supports the following line cards (modules):
CDM is a software application that you can use to monitor the Cisco 6100 Series system chassis. Cisco EMF is the software interface that allows you to view this information. CDM creates new views and the GUI windows.
A diagram of CDM and DSLAM chassis interrelationship is shown in Figure 1-1. This diagram shows an example deployment and interconnection scenario for a Cisco DSLAM, where it is connected to a Cisco 6400 Universal Access Concentrator (UAC) system. Figure 1-1 also demonstrates the subtending feature of the Cisco DSLAM.
|
Note Figure 1-1 shows connections between the Cisco DSLAM and the Cisco 6400 UAC as direct connections. It is also possible for these connections to be indirect (that is, through a switched network). Other configurations may use different components. |
This section provides an overview of the Cisco EMF and CDM software applications and includes the following topics:
Cisco EMF is an open-carrier class management system that can integrate with third-party products and proprietary operational support systems. Cisco EMF supports many different management protocols, both standards-based and proprietary, in a way that is transparent to you.
CDM is the carrier-class management software for Cisco DSLAMs and is integrated into Cisco EMF. You must launch a Cisco EMF user session before you can run the CDM application; CDM automatically launches when you start Cisco EMF. You can access all CDM information through the Cisco EMF Launchpad window. The "Starting a Cisco EMF User Session" section provides instructions for launching Cisco EMF.
The Cisco EMF architecture provides a distributed network management solution that can manage large-scale networks. Cisco EMF provides user interfaces that support mass operations to large domains within the overall network as well as administration tools to manage the management system.
The Map Viewer window is the primary entry point into CDM. When you open the Map Viewer window, a hierarchical system displays. You can easily monitor the status of all network elements or abstractions of elements that the network contains, and you can launch any additional applications that are available to you.
Cisco EMF supports multiuser access. When multiple users are managing the network through Cisco EMF, the GUI windows on all workstations automatically update to reflect the most recent status changes that users make. You can enable or disable these automatic updates.
You can also run multiple event browsers and map managers on separate client workstations, which allows several users to simultaneously monitor the same or distinct portions of the managed network.
Users can run all of their applications on client workstations that are remote from the server. This remote access means that the load on the server depends only on how much data you request from it. Therefore, the resources that applications require only minimally impact how many users can also be using the client.
Cisco EMF allows for concurrent user sessions. Each user session has access to tools on the Cisco EMF Launchpad. Any changes that users make during a session immediately reflect in all other user sessions. Cisco EMF restricts user access to CDM based on a preset name and password combination that the system administrator defines.
Cisco EMF maintains a login record of users who access the Element Manager windows. This information is output as ASCII text files named ciscoModuleMan.audit and ciscoPlatformMan.audit. You can locate these files in <CEMFROOT>/logs (replace <CEMFROOT> with the Cisco EMF installation directory.)
This section provides an overview of using the Cisco EMF Launchpad, through which you launch element management applications. This section includes the following topics:
To use CDM, you must first open the Cisco EMF Launchpad window, shown in Figure 1-2, and here after referred to as the Launchpad.
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 the application:
|
Note If you install additional software packages, other icons might appear on the Launchpad. |
|
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 Viewer icon, shown in Figure 1-3, opens the Cisco EMF Viewer application, through which you can view, build, and monitor your network by using graphical representations of network elements.
Click the Viewer icon to launch the Map Viewer window, from which you run CDM; in other words, 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; you can launch any additional applications from the Launchpad.
Click the Groups icon, shown in Figure 1-4, to launch the Cisco EMF Object Group Manager application. You can also select Groups from an object menu when using other Cisco EMF applications.
You can use the Cisco EMF Object Group Manager, called Groups, to organize network elements into object groups.
Click the Access icon, shown in Figure 1-5, to open the Cisco EMF User Access Control manager application.
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.
The Events icon, shown in Figure 1-6, opens 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 the "Using the Event Browser Window to View Alarms" section 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 might require a field service call. This fault is critical and would need prompt attention.
The Discovery icon, shown in Figure 1-7, opens the Cisco EMF Auto Discovery application. 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 on the Event Manager area of the Launchpad and includes the following topics:
The Notify icon, which is shown in Figure 1-8, launches the notification profile application.
Cisco EMF uses notifications to inform operators that Cisco EMF has been monitoring network events.
You can set notification profiles to specify how notifications are collected. Refer to the Notification Profiles chapter in the Cisco Element Management Framework User Guide for more detailed information.
The Thresholds icon, which is shown in Figure 1-9, launches 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 on Thresholding Regimes in the Cisco Element Management Framework User Guide for more detailed information.
The Event Grps icon, which is shown in Figure 1-10, launches 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 on event groups in the Cisco Element Management Framework User Guide for more detailed information.
The CDM GUI, based on the Cisco EMF application, includes several types of navigational tools. These tools include maps, the menu bar, the toolbar, tooltips, window menus, object menus, and lists, and are described in the following sections:
A map is a graphical representation of related managed objects. You can view different levels of complexity in the managed network by looking at high-level maps or by navigating to submaps, which represent lower levels of detail in the managed network. Maps can include nodes, links, submaps, and map status, which is characterized by event propagation. Map objects are described in Table 1-1.
The Map Viewer windows contain the main menus with the noted choices that are described in Table 1-2. The menu bar contains some or all of these menus, and the menus contain some or all of these choices, depending upon the window from which you are accessing the menu bar.
A toolbar at the top of each window on the CDM GUI contains icons that invoke various tools and menu options. The toolbar is shown in Figure 1-11.
The icons that display in the toolbar vary depending on which window you are viewing. If you want to hide the toolbar, disable it by deselecting Show Toolbar from the Options menu.
The tooltips feature is enabled by default. Place your cursor over an icon for a few seconds to see the tooltip for that icon. The tooltips feature displays a brief description of each icon. If you want to hide tooltips, disable it by deselecting Enable Tooltip from the Options menu.
The tooltips are especially helpful when you are setting subscriber properties. As you set the values for each of the subscriber properties, the tooltips display the valid and available values for each setting. See "Creating and Adding Subscriber Properties," for instructions on setting subscriber properties.
This section describes the other GUI navigational tools and includes the following topics:
|
Note Refer to the "Graphical Cues" and the "Informational Icons" sections of the Cisco Element Manager Framework User Guide for information about Cisco EMF graphical cues that you see on the CDM GUI. |
You can access menus from map objects, events listed in the Event Browser window, and objects listed in any view. These are referred to as object menus. To access object menus, right-click the object whose menu you want to access. The menu choices that are available for an object depend on the object class and the access privileges of the user; object menus are context sensitive.
To access object menus for specific managed objects:
|
Note Alternatively, you can highlight the C6100v30[name of module or line card] within the C6100v30ManagedElement in the Physical hierarchy view. This action displays all the icons associated with the managed object on the right side of the window. |
Step 2 Right-click over the appropriate icon to open the object menu.
An example object menu is shown in Figure 1-12.
When you place your cursor over a module and right-click, you access the module object menu, shown in Figure 1-13.
By moving your cursor to the right of a menu item that displays a right-facing arrow, you access a submenu.
For example, if you move your cursor to the right of the Deployment option on the object menu, you see the submenu that is shown in Figure 1-14.
Also, if you move your cursor to the right of the Map option on the object menu, you see the submenu that is shown in Figure 1-15.
If you move your cursor to the right of the Tools option on the object menu, you see the submenu that is shown in Figure 1-16.
If you move your cursor to the right of the View Manipulation option on the object menu, you see the submenu that is shown in Figure 1-17.
The object menu that opens when you right-click over the managed object from the map on the left of the Map Viewer window, shown in Figure 1-18, includes a number of choices. From this menu, you can open various windows on which you create and manage various aspects of your system.
You can select either individual or multiple items from lists in various windows. More details about specific lists are described in the individual procedures throughout this guide. Lists appear on the left side of windows in a scroll area. When lists display on the left side of a window, you need to select an object from the list to specify that object for the actions that you take on the right side of the window. An example of a list is shown in Figure 1-19.
In this window, you select the STU-C modem port from the list on the left whose status you want to view.
This section describes two GUI elements that you see frequently when using CDM and includes the following topics:
The Action Report window, which is shown in Figure 1-20, opens after you do various tasks to inform you of the status.
The information in this window includes failures and successful actions. Use the Action Report window as follows:
Step 2 Click Save to save this data to a log file.
If you click Save, the File Chooser window, which is shown in Figure 1-21, opens.
Step 3 Use the File Filter field to search in your directory structure for the directory where you want to save the log file.
Step 4 Click Filter to use the File Filter field.
The path in the File Filter field reflects in the Choice field.
Step 5 You can manually enter the directory path and file name in the Choice field, as well.
Step 6 Click Apply to save the file.
An example confirmation dialog box is shown in Figure 1-22. The confirmation dialog box opens after most actions you take that involve changing any values.
The message in the dialog box asks you to confirm or cancel the action that you have initiated on the GUI. Click Yes to proceed with the action, or No to cancel.
Telecom 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.
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.
Each telecom graphical object can display the following information about its associated network element:
This section describes the Map Viewer window hierarchical views and includes the following topics:
The 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 view format. The graphical representation of an object that you select on the left displays on the right side of the window. You can view several maps at once in different windows.
To resize the hierarchy and map areas, position your cursor over the boundary, and click and drag the boundary. You can view all information in the left and right sides of a window by using the horizontal and vertical scroll bars.
Figure 1-24 shows a top-level CDM hierarchy view.
The names that are shown in Figure 1-24 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 CDM. You can accomplish most CDM-specific tasks by using the CDM Manager view, which is labeled C6100v30Mgr. Using the 61xxChassisView, you can look at physical maps of each Cisco DSLAM chassis. You can access object menus by right-clicking any object. You can also click the "+" next to the 61xxChassisView to find the Managed Element list.
CDM NI-1 has the following hierarchy views:
These hierarchy views are described in the following sections.
The C61xxChassisView hierarchy provides a complete Managed Element list as well as all the managed objects within that list. From this hierarchy you can see which DSLAMs are being managed and the types of modules and line card interfaces that are present in each DSLAM. You can determine the chassis section and slot number for each module and port by looking at the numbers on the right of each entry. The colored circles indicate the status of each managed element.
To navigate in this hierarchy:
|
Note To see the line card ports or subscribers, you must navigate through the Physical or C6100v30Mgr hierarchy views, as described in the "Physical Hierarchy View" section on page 1-22. |
The CDM Manager (C6100v30Mgr) hierarchy view is shown in Figure 1-25.
The C6100v30Mgr hierarchy view gives a complete overview of all the managed objects within that view. From this view you can see which DSLAMs are being managed and the types of modules and line card interfaces that are present in each DSLAM. You can determine the chassis section and slot number for each module and port by looking at the numbers on the right of each entry. The colored circles indicate the status of each managed element.
From the CDM Manager hierarchy view, you can also see subscriber data and pool information.
The Network hierarchy view represents the network devices within their respective networks and subnetworks. An example of this view is shown in Figure 1-26.
The autodiscovery subsystem uses this view to determine which devices CDM has already added to the system. This utility 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 hierarchy 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 hierarchy view is shown in Figure 1-27.
The Physical hierarchy view, which is shown in Figure 1-28, reflects the physical relationship of objects and provides relevant information to create maps.
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 this view, but that is a matter of personal preference. To access the chassis view, see the "CDM Chassis View" section.
An example diagram of a physical hierarchy view is shown in Figure 1-29.
|
Note Figure 1-29 shows an example overview of a physical hierarchy with relationships between objects in a CDM NI-1 environment. DMT-2, Flexi, and STU-C are only supported in Direct Connect mode and would not, therefore, include a line controller module. |
The Physical hierarchy 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.
To run CDM, you must first start a Cisco EMF user session; when you launch Cisco EMF, CDM also launches. Each active Cisco EMF session uses a single Cisco EMF user license. Element Managers for the chassis also launch in the Launchpad. For more information about using the Element Manager, refer to the Cisco 6130 NI-1 Element Manager User Guide.
Complete the following steps to start a Cisco EMF user session. You should have a Unix terminal window open to begin the Cisco EMF session. For an overview of the Launchpad icons, see the "Using the Cisco EMF Launchpad" section.
Replace <CEMFROOT> with the root directory where Cisco EMF 3.2 is installed (for example, /opt/cemf32).
The Login window shown in Figure 1-30 appears.
Step 2 Enter your user name and password, and then click OK to proceed.
If you enter invalid information in the User Name or Password fields, an error message displays. If you get this error message, click OK, and then enter a valid user name and password.
|
Note You have three attempts to enter a valid user name and password. If, after three attempts, the system does not recognize your user name and password as valid, the session fails to start and the Login window closes. |
When you enter a valid user name and the password, the session starts and Launchpad opens.
Instructions for ending a Cisco EMF user session are included in the next section for reference. See the "Getting Started Using CDM" section for instructions to start using CDM.
To end or exit a Cisco EMF user session, follow these steps:
A dialog box opens that asks whether you wish to quit the Cisco EMF Manager System.
Step 2 Click Yes to quit the session.
All active applications close and the session terminates.
When you first open CDM by clicking the Viewer to open the Map Viewer window, the window that is shown in Figure 1-32, opens.
The Map Viewer window uses graphical representations of network elements, through which you can view, build, and monitor your network. An example of the Map Viewer window showing the graphical representation of a chassis is shown in Figure 1-33. This is the view that you see after you have deployed the chassis and modules (line cards), commissioned them, and synchronized your system. (See "Deploying DSLAM Chassis and Modules," for these procedures.)
As CDM is deploying and synchronizing a chassis, arrows that are pointing up appear on each module. When the arrows disappear, that is an indication that CDM has deployed and synchronized that module.
To view the chassis map for a selected site, follow these steps:
Step 2 Click Viewer to open the Map Viewer window.
Step 3 To display the menu choices that are available for an object, right-click the object.
Step 4 Click + to the left of C6100v3Managed Element below the Physical hierarchy view to display objects within that view.
Step 5 To view a chassis, such as the one shown in Figure 1-33, click a C6100v30ManagedElement from the C61xxChassis view.
Step 6 Right-click any modules within the chassis, or the chassis itself, to open the object menus for specific modules or chassis.
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 Manager Framework User Guide for more detailed information about Cisco EMF graphical cues, including alarm and object status, that you see on 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.
