This chapter provides an overview of the Cisco Digital Subscriber Line Manager (CDM) application, which uses the Cisco Element Management Framework (EMF). For further information about the basic concepts of the Cisco EMF, refer to the Cisco Element Management Framework User Guide, which describes the Cisco EMF commands, icons, and menus used to access services.
Cisco EMF is an open carrier class management system that integrates with third-party products and proprietary operational support systems. The Cisco Element Management Framework User Guide provides information about the application.
Several management protocols, both standards-based and proprietary, are supported by Cisco EMF in a manner transparent to the applications that access the network. This leads to new network devices being managed instantly and new management applications being developed quickly to meet new requirements.
The Launchpad icons, shown in Figure 1-1, represent the standard Cisco EMF tools.
Click the appropriate icon to launch an Cisco EMF tool:
 |
Note Additional icons may appear if additional packages are installed. The icons appear in a frame identified by the package name. For more information on the Cisco EMF Launchpad, refer to the Cisco Element Management Framework User Guide. |
Additionally, you can run multiple event browsers and map viewers on separate client workstations. This provides the option for a number of users to simultaneously monitor the same or distinct portions of the managed network.
You can run all of a user's applications on client workstations located remotely from the server. This means that the load on the server is dependent only on the quantity of data the user requests from the server.
If more than one user accesses the same network element through any of the CDM windows, the windows on other users' workstations are automatically updated to reflect the most recent status changes made by any user. To enable or disable automatic updates, use the Dynamic Update facility.
A map is a graphical representation of related managed objects. Maps can be defined in a hierarchy, with each node on a map having a sub-map. You can view several levels of complexity in a managed network by looking at high level maps or by navigating to sub-maps. These sub-maps represent lower levels of detail in the managed network.
Nodes and links on a map are graphical symbols which represent managed objects in the network or abstracted objects.
Nodes have sub-maps that definine a hierarchy of maps, which you can browse. You can use top-level maps to display administrative or physical network domains. You can navigate through sub-maps to display more detail or to locate manageable elements.
A network node displays the current event or alarm status of the object it represents. The alarm status of an object is the severity of the most severe alarm that is currently active on the object.
A sub-map propagates the most severe event or alarm status of all its nodes to the node on the parent map through which a sub-map can be accessed. The node on the parent map then displays the combined severity of its sub-map and the node it represents.
Thus, a user can view a top level map and see the overall status of the network. When a node on the map shows a condition, the user can view successive sub-maps until they see the source of the condition.
You can carry out tasks on any managed objects. These tasks or functions are referred to as services on objects. To access a service on an object, go to Map Viewer, Event Browser and Object Group Manager.
You can selectan object and right-click to show a list of services or actions available on the object in a pop-up menu.
This section describes how to access and use the key features contained within the Cisco Digital Subscriber Line Manager (CDM). The CDM runs on the Cisco EMF, which provides generic network management functions and capabilities.
|
Note CDM contains online help. |
Use the Login window to control user access to the CDM using a pre-set name and password combination. An administrator can define the password and user name.
To start a client application (that is, to access the user graphical user interface (GUI) windows):
|
Note Clients refers to both clients on the CDM server and clients on a different host from the server. |
Step 2 The Login window appears. You are prompted to enter your user name and a password. The default user name is admin and the default password is admin.
Step 3 The Launchpad window appears. Refer to the "Using the Cisco EMF Launchpad" section.
A log in record of users who access GUI windows is maintained on each client. This information is provided as ASCII text files such as c6260Manager.audit and C6260SSManager.audit for the Cisco 6260, which can be found in <AVROOT>/logs.
Use the Cisco Digital Subscriber Line Manager (CDM) Version 1.1 to configure and monitor systems that include up to two NI-2 cards and up to 30 line cards. Each line card contains multiple ports. You can connect each port to a subscriber using an xDSL modem.
CDM Version 1.1 supports DS3 NI-2 cards in addition to OC-3 NI-2 cards. Therefore, the examples in this guide center on the DS3 NI-2 card.
The following classes of objects are identified in the CDM:
Map Viewer displays a graphical representation of a selected Cisco 6000 series chassis, and is the main login point into the CDM system after the site is initially deployed through the Object Manager. For more information, refer to the "Displaying Objects" section.
To display a selected Cisco 6000 series chassis or enter the CDM system, access the Map Viewer as follows:
|
Note To view the Map Viewer window, select the object, right click, and select the AV Tools -\> Open Map For Object option from the drop-down menu. This option is not inoperable on the Manager object. |
Step 2 The Map Viewer window is divided into two information areas, the hierarchy pane and the map pane. To re-size a section, drag the boundary to the required position.
The map pane displays a map of the selected object. In Figure 1-2, the empty slots are grayed and the slots with either the line cards or the NI-2 cards are represented with images.
|
Note To show a pop-up menu which lists services available on an object, right-click the object. |
You can change the mode from Map Hierarchy to View or Build:
Use the hierarchy pane to navigate through the sub-maps. To view the relevant sub-map on the map pane, double-click any of the nodes in the tree.
Use the hierarchy pane to navigate around the maps in the system. When you launch Map Viewer, the hierarchy pane displays the Root icon and an icon for each top-level map. There are two icon types that can appear in the hierarchy pane:
1. Map with sub-maps
2. Map without sub-maps
The map currently displayed in the map pane has its corresponding map icon highlighted in the hierarchy pane.
Use the map pane to:
The map can contain nodes and links. There are three types of nodes and 10 types of links. Each node on a map that has an object assigned to it has a colored status bar (for icons) or colored background (for nodes). The color corresponds to the highest event severity reported by the object, or any object in a sub-map assigned to the object.
The severity of events and their corresponding colors are shown in Table 1-1.
| Color | Severity of Events |
|---|---|
Red | Critical |
Orange | Major |
Yellow | Minor |
Cyan | Warning |
Green | No Events (Normal) |
Blue | Card decommissioned or not installed |
White | Informational |
Dark green | Preprovision |
To view events that are flagged by the system, use the Event Browser.
CDM identifies events generated by SNMP traps. You can locate the source of an event by navigating within the Event Browser.
|
Note For further information on Event Browser, refer to Cisco Element Management Framework User Guide. |
All network objects display in a color code that identifies the operational status. Events can be propagated up the element hierarchy according to severity. Refer to Table 1-1.
All events are stored within the Event Browser which shows current and historical data.To perform detailed configuration, navigate directly from a single event within the browser to the affected object.
Additionally, the CDM can be complemented by the Event Manager application. Among other features, the Event Manager application enables thresholds to be set to monitor any supported Element Manager MIB variable (that is, those which appear on the CDM Element Manager GUIs).
Use Object Manager to:
|
Note For further information about the Object Manager feature, refer to Cisco Element Management Framework User Guide. |
To add new users to the system, remove users, and change passwords, a system administrator uses the Access Manager application. The system administrator, whose user name is admin, can add or delete any user name and change any password without knowing the user's former password.
|
Note For further information about the Access Manager feature, refer to Cisco Element Management Framework User Guide. |
This section describes how to access and use the key features contained within Cisco Digital Subscriber Line Manager (CDM) windows.
|
Note For more detailed information, refer to Cisco Element Management Framework User Guide. |
The layout of a typical CDM graphical user interface (GUI) window appears in Figure 1-3:
The following selections appear on a typical Cisco Digital Subscriber Line Manager (CDM) window:
Use the File menu item to:
Use the Edit menu item to copy, paste, delete, or edit text.
Use the Options menu item to acknowledge changes, and to toggle Dynamic Update on or off.
Use the Navigation menu item to access a drop-down list of tasks.
Use the Window menu item to view a window that is open. Select the Window option and select the window you require from the drop-down list. When a window is left open, it appears in this list.
Use the Action menu item to view the commands available for the selected windows.
Use the Help menu item to get help on a selected option.
The toolbar at the top of each window contains icon buttons which invoke various tools and menu options (Figure 1-4).
|
Note The icons in the toolbar vary depending on the window that is open. |
The ToolTips option displays a brief description of the tool or icon that the cursor is left over. ToolTips is enabled as default. When you place the cursor on an attribute in any window, a ToolTip shows the function of the selected attribute.
|
Note Enable ToolTips toggles ToolTips on and off. If a square appears to the left of Enable ToolTips, then ToolTips is enabled. |
If a window covers several areas of information, the window may appear divided into tabs. To view related attributes and to perform specific operations, select the required tab.
To enter a string within a specific range, use the Data Entry box.
To display the options that are assigned to a selected parameter, click the combo box.
System status information (such as commissioned, decommissioned, normal) appears in the information display area at the bottom of the window.
The Status information area shows the current status of the selected object. To view recent status messages in the Status window, double-click the status display area.
To display the status, use the Update button at the bottom of each window:
In Cisco EMF, the relationship between objects is modeled by parent and child containment trees. Each object has parents and children in one or more containment trees. Each tree represents a different view of the managed network, such as:
You can access CDM objects by navigating through one of the containment trees to find the object.
The following containments provide the most logical views of the networks and it is recommended that you use them in the CDM Element Manager:
|
Note SNMP Containment and profileContainment are available, but not used on the CDM Element Manager. |
The mgmtContainment tree holds all of the managed objects in the network and shows the management relationships between objects. In general, objects positioned at lower levels in a tree are managed by objects located above them in the tree. The CDM server object is always located at the top of the mgmtContainment tree (Figure 1-5).
The physContainment tree holds location information for all of the equipment in the network. The relationships defined in the physContainment tree are physical containment relationships. For example, a bay appears below a central office because the bay is physically contained inside the central office (Figure 1-6).
The networkContainment tree displays all IP devices under a parent network. The networkContainment tree provides a logical view of the network structure. It does not provide topology information (Figure 1-7).
The mapObjectContainment tree is the only containment tree that defines the exact event propagation path. The mapObjectContainment tree is used to reflect the relationship between maps, and displays a chassis front panel representation of the contents of the chassis (Figure 1-8).
|
Note Objects can exist in multiple trees simultaneously (by reference). |
The Subtend containmment tree is used to view the subtended relationship between NI-2s (Figure 1-9). The Subtend containmment tree is populated during the deployment process using the Deployment Wizard and is not auto discovered.
The pvcdialogContainment defines the location of PVCs within the hierarchical path from the chassis shelf down to the ATM layer over which the PVC runs (Figure 1-10).
