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 Manager 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 the 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 3.0 supports the following line cards (modules):
|
Note CAP ATU-C, DMT-2 ATU-C, STU-C, and Flexi ATU-C modules support Direct Connect configurations. CAP ATU-C modules are the only type of line card that supports Digital Off-Hook configurations. |
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. |
CDM is the carrier-class management software for Cisco DSLAMs and is integrated into the 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 map 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.
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.
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 on the Launchpad represent applications that the current Cisco EMF version provides. The icons that are shown in Figure 1-2 represent the standard Cisco EMF tools and include Viewer, Groups, Access, Events, and Discovery, which are described in the following sections.
|
Note If you install additional software packages, other icons can appear on the Launchpad. |
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.
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.
| Object | Description |
|---|---|
Nodes and Links | Nodes and links on a map are graphical symbols that represent managed or abstract objects in a network. A node has an iconic representation, while a link has a vector representation. Links can only exist as a connection between two nodes. |
Submaps | Nodes and links can have submaps, thus creating a hierarchy of navigable maps. Top level maps display administrative or physical network domains; submaps display more detail until actual managed elements are represented. |
Status | Network nodes display the current alarm status of a represented object. The alarm status of an object reflects the most severe alarm that is currently active for an object. |
Event Propagation | A submap displays the most severe alarm status of all its nodes to the corresponding node on the parent map. The node on the parent map then displays the combined severity of its submap and the node it represents. This hierarchical propagation means that you can view a top level map and see the overall status of the entire network. When a node on the map shows a condition or alarm, you can view successive submaps until the source of the condition or alarm appears. |
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.
| Menu | Choices |
|---|---|
File | Print, Close, Save |
View | Open Parent Map, View Map Description, Sort by Class, Sort by Name |
Options | Show Toolbar, Enable Tooltip |
Windows | Cisco Element Manager Framework Launchpad and any other open windows |
Navigation | Can include the following choices for opening various dialog windows: |
Actions | Choices from this menu depend on which window you are in. Example choices are Create Subscriber, Create New Module, and Set Data. |
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 1-8.
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.
Other GUI tools that you can use to navigate through the system and open various windows include object menus and lists. 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. Additionally, 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.
An example object menu is shown in Figure 1-9.
When you place your cursor over a module and right-click, you access the module object menu, shown in Figure 1-10.
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 1-11.
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 1-12.
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 1-13.
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 1-14.
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 1-15, includes a number of choices. From this menu, you can open various windows on which you create and manage various aspects of your system.
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 1-16.
In this window, you select the STU-C modem port from the list on the left whose status you want to view.
Two GUI elements that you see frequently when using CDM are the Action Report window and the confirmation dialog box.
The Action Report window, which is shown in Figure 1-17, 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 1-18, 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 1-19. 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.
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:
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. 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.
The top level CDM map hierarchy view is shown in Figure 1-21.
The names that are shown in Figure 1-21 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 CDM Manager view, which is labeled C6100v30Mgr. In this view, you can look at physical maps of each Cisco DSLAM chassis. You can access object menus by right-clicking any object.
CDM NI-1 has the following map hierarchy views:
These map hierarchy views are described in the following sections.
The CDM Manager, labeled C6100v30Mgr, map hierarchy view is shown in Figure 1-22.
The C6100v30Mgr View map gives a complete overview of all the managed objects within that view. From this map 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 this CDM Manager view, you can also see subscriber data and pool information.
The Network map hierarchy view represents the network devices within their respective networks and subnetworks. An example of this view is shown in Figure 1-23.
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 1-24.
The Physical map hierarchy view, which is shown in Figure 1-25, reflects the physical relationship of objects and provides relevant information to draw maps. From this view, you can click C6100v30Multiplexer Chassis to open the chassis view on the right; you cannot open the chassis view from the C6100v30Mgr map.
The Physical map 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.
An example diagram of a physical view is shown in Figure 1-26.
|
Note Figure 1-26 shows an overview physical map with all possible relationships between objects in a CDM NI-1 environment; Flexi and STU-C are only supported in Direct Connect mode and would not, therefore, include a line controller chassis. |
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.
The Subtend Map view is shown in Figure 1-27.
|
Note The Subtend Map hierarchy view is not fully functional with this release of CDM. |
The Generic Objects map hierarchy view contains the generic objects from Cisco EMF, networks, and sites. An example of this view is shown in Figure 1-28.
A diagram of the Generic Objects view is shown in Figure 1-29.
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 3.0 is installed (for example, /opt/cemf3).
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 from 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:
|
Note See the "Starting a Cisco EMF User Session" section for instructions. |
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 view to display objects within that view.
Step 5 To view a chassis, such as the one shown in Figure 1-33, click a C100v30Multiplexer Chassis from the C6100v30Mgr 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.
