This chapter describes the procedures for managing Cisco uBR7200 series universal broadband routers and cable modems. Cisco Cable Manager runs as part of the Cisco Element Manager Framework (Cisco EMF) and provides the following features:
This chapter describes the following procedures:
After successfully completing the installation steps, Cisco Cable Manager can be started. To start Cisco Cable Manager server for the first time, log in as root and enter the following commands:
cd /opt/AV/bin
./av start
./av dataload
After Cisco Cable Manager has been started for the first time, it can be restarted using the command:
./av start
Cisco IP Manager and Oracle server are optional and can be installed to enable Cisco Cable Manager configuration management. If you plan to use configuration management, start the required network components and Cisco Cable Manager in the following order:
1. Oracle server
2. Cisco IP Manager
3. Cisco Cable Manager
After successfully completing the installation steps and running Oracle and Cisco IP Manager, Cisco Cable Manager can be started. To start Cisco Cable Manager server for the first time, log in as root and enter the following commands:
cd /opt/AV/bin
./av start
./av dataload
After Cisco Cable Manager has been started for the first time, it can be restarted using the command:
./av start
To access Cisco Element Management Framework (CEMF) and Cisco Cable Manager, ensure the Cisco Cable Manager server is started and complete one of the following operations:
Enter a valid username and password. The default username is admin. The default password is admin. Admin or root users can add additional users and passwords.
After CEMF and Cisco Cable Manager are started, the CEMF application window appears with the Launch Pad.
Figure 3-1 shows the CEMF Launch Pad.
The first step in managing a device is to deploy CEMF management containment levels and objects. To deploy containment levels and objects, click Objects. The Object tree appears with the default Manager level as the top level.
To assign additional levels and objects, from the right-click menu, select Deploy Object and choose the desired level. The CEMF management levels are region, site, network, and bay. Cisco Cable Manager containment levels include Cisco uBR7200 series universal broadband routers, RF line cards, port adapters, upstream connections, and downstream connections. Cable modem objects appear under the upstream connections.
After the containment levels are created, the objects can be deployed. By default, performance polling is disabled for the deployed or discovered objects. Performance polling can be activated per Cisco uBR7200 series universal broadband router. See "Enabling/Disabling Cable Modem Performance Polling" section.
In CEMF, "deployment" can be carried out on actual or soon-to-be installed hardware devices through these methods. Cisco recommends that you "discover" each Cisco uBR7200 series universal broadband router individually.
Use the CEMF Autodiscovery function to automatically discover existing Cisco uBR7200 series universal broadband routers already physically installed on your network by IP address range of the Cisco uBR7200 series universal broadband routers and display them and their objects in the CEMF tree views. Cisco recommends that you "discover" each Cisco uBR7200 series universal broadband router individually. Due to the size restrictions of the alarm database, Cisco recommends that you reset the alarm database after the initial discovery of every 2,000 cable modems or manually delete the alarms from the alarm database.
Step 1 In the CEMF tree view, right-click the level under which you want to deploy devices. This displays the Options menu.
Step 2 Select Autodiscovery to display the Discover Network Devices dialog. Run the Discovery process as described in your CEMF documentation. You will need to enter the IP addresses, SNMP read-only string, and physical path. This read-only string needs to match the Cisco uBR7200 string setting. If the strings do not match, Cisco Cable Manager will not discover the Cisco uBR7200 series universal broadband routers. The Cisco uBR7200 series universal broadband router community strings can be set individually using the CEMF Open Configuration menu command.
To check the status of the autodiscovery process, select a Cisco uBR7200 series universal broadband router and from the right-click menu, choose Commission/Decommission Object. The Commission/Decommission dialog appears and displays the object status. A status of "normal" indicates the Cisco uBR7200 series universal broadband router and its components have been discovered. You can also verify the status of the autodiscovery process by accessing the AV log file.
Due to the size restrictions of the alarm database, Cisco recommends that you reset the alarm database after the initial discovery of every 2,000 cable modems or manually delete the alarms from the alarm database.
To reset the alarm database after the initial discovery of every 2,000 cable modems, follow these procedures:
Step 1 Ensure you are logged in to Cisco Cable Manager server as user root.
Step 2 When all the cable modems connected to a Cisco uBR7200 series universal broadband router have been discovered, execute the /opt/AV/bin/av stop command to gracefully bring down Cisco Cable Manager.
Typically, Cisco uBR7200 series universal broadband routers are discovered individually. When all the cable modems connected to an individual Cisco uBR7200 series universal broadband router have been discovered, the numbers of lines in the /tmp/ip-address-file(s) file matches the number of lines in the /tmp/cmHashTable file.
Step 3 To stop the Object Store server, execute the /etc/init.d/S80ostore4 command.
Step 4 Move to the /opt/AV/db directory and either copy the alarm.db file to another filename and remove the original file or move the alarm.db file to another directory location.
Step 5 Ensure the OS_CACHE_SIZE is set to 64 MB. Refer to instructions under CShell, setenv OS_CACHE_SIZE 67108864.
Step 6 To restart the Object Store server, execute the /etc/init.d/S80ostore4 start command.
Step 7 To start CEMF and Cisco Cable Manager, execute the /opt/AV/bin/av start command.
Step 8 Continue the discovery process for the next Cisco uBR7200 series universal broadband router deployment and cable modem object creation. Repeat these steps to reset the alarm database after all the connected cable modems for the Cisco uBR7200 series universal broadband router have been discovered.
By default, performance polling is disabled for the deployed or discovered objects. Cable modem performance polling can be activated per Cisco uBR7200 series universal broadband router and is used to collect data for the cable modem customized report.
To enable polling for a Cisco uBR7200 series universal broadband router:
Step 1 Select the desired Cisco uBR7200 series universal broadband router in the Object or Map View.
Step 2 Select AV Tools>Open Configuration Dialog.
Step 3 Verify the COMMON-EM.mib:controllerState attribute has a value of normal. Performance polling can only be set for objects with a value of normal-.
Step 4 Change the COMMON-EM.mib:controllerAction attribute value from ERROR to startPolling.
Step 5 Click Save.
Step 6 To verify performance polling is activated, in the Open Configuration dialog box, verify the COMMON-EM.mib:controllerState value is perPolling.
As an alternative to running the automated deployment of the Autodiscovery function, the CEMF Deployment feature allows you to manually deploy containment levels and their objects or only individual objects. Cisco Cable Manager devices include Cisco uBR7200 series universal broadband routers RF line cards, port adapters, upstream connections, and downstream connections. Cable modems appear under the upstream connections.
Cisco recommends that you discover each Cisco uBR7200 series universal broadband router individually. Due to the size restrictions of the alarm database, Cisco recommends that you reset the alarm database after the initial discovery of every 2,000 cable modems or manually delete the alarms from the alarm database.
To manually discover an object:
Step 1 In the CEMF tree view, right-click Object level or the Cisco uBR7200 series universal broadband router that you wish to deploy. This displays the options menu.
Step 2 Select the desired deployment option:
For a Cisco uBR7200 series universal broadband router level, from the right-click menu:
Step 3 In the following Deployment Selection Screen, specify the desired information and click Forward:
Step 4 When deployment is complete, the Deployment Summary screen appears. Click Dismiss. Your newly deployed objects will appear in the CEMF Map View and Object Tree.
Step 5 Commission the containment level so the containment object and the manually deployed objects are synchronized.
Due to the size restrictions of the alarm database, Cisco recommends that you reset the alarm database after the initial discovery of every 2,000 cable modems or manually delete the alarms from the alarm database.
To reset the alarm database after the initial discovery of every 2,000 cable modems, follow these procedures:
Step 1 Ensure you are logged in to Cisco Cable Manager server as user root.
Step 2 When all the cable modems connected to a Cisco uBR7200 series universal broadband router have been discovered, execute the /opt/AV/bin/av stop command to gracefully bring down Cisco Cable Manager.
Typically, Cisco uBR7200 series universal broadband routers are discovered individually. When all the cable modems connected to an individual Cisco uBR7200 series universal broadband router have been discovered, the numbers of lines in the /tmp/ip-address-file(s) file matches the number of lines in the /tmp/cmHashTable file.
Step 3 To stop the Object Store server, execute the /etc/init.d/S80ostore4 command.
Step 4 Move to the /opt/AV/db directory and either copy the alarm.db file to another filename and remove the original file or move the alarm.db file to another directory location.
Step 5 Ensure the OS_CACHE_SIZE is set to 64 MB. Refer to instructions under CShell, setenv OS_CACHE_SIZE 67108864.
Step 6 To restart the Object Store server, execute the /etc/init.d/S80ostore4 start command.
Step 7 To start CEMF and Cisco Cable Manager, execute the /opt/AV/bin/av start command.
Step 8 Continue the discovery process for the next Cisco uBR7200 series universal broadband router deployment and cable modem object creation. Repeat these steps to reset the alarm database after all the connected cable modems for the Cisco uBR7200 series universal broadband router have been discovered.
After the containment levels are created, the objects can be deployed. By default, performance polling is disabled for the deployed or discovered objects. Performance polling can be activated per Cisco uBR7200 series universal broadband router. See "Enabling/Disabling Cable Modem Performance Polling" section.
After a device is discovered and deployed, Cisco Cable Manager allows you to add devices to be managed (commission) and remove devices from being managed (decommission).
You can commission/decommission single Cisco uBR7200 series universal broadband routers and all the cable modems connected to the router, a single RF line card or a single port adapter. You can also commission all the objects under a Cisco uBR7200 series universal broadband router by decommissioning the router and then recommissioning it.
To commission or decommission an object, select the desired object and from the right-click menu, select the displayed commission/decommision command. The Open Commission/Decommision dialog box appears.
Figure 3-2 shows the Commission/Decommission dialog box.
In the Cisco Cable Manager Launch Pad, select the desired view and toggle to the desired cable object. To access the Cisco Cable Manager features, select the desired object and choose an option from the right-click menu.
Cisco Cable Manager enables you to perform the following Cisco uBR7200 series router management features:
Cisco Cable Manager integrates fault management with Cisco EMF/EM so you can:
To display event messages:
By default, event messages are stored for seven days. This setting is controlled by the alarmDirServer.ini file located in the /opt/AV/config/init directory.
Make sure the desired Cisco uBR7200 series universal broadband routers are configured to send traps to the Cisco Cable Manager. This configuration involves enabling traps, specifying a source interface for SNMP traps, setting destination host IP addresses, and ensuring the cable modem MIB is set.
To enable the cable-specific SNMP traps, configure the Cisco uBR7200 series universal broadband router with the following commands:
snmp-server enable traps
snmp-server trap-source [interface port/slot]
snmp-server host [IP address] [community string]
Multiple host IP addresses can be entered to forward traps to multiple SNMP management stations.
The SetCmOnOff.pl script is an additional tool distributed with the Cisco Cable Manager and located under /opt/AV/config/scripts. This script enables the cdxCmtsCmOnOffTrap with a default interval of 600 seconds (10 minutes). The interval determines how long the system waits after the event occurs before sending out the trap message. You have the option of not using this script if other tools are available.
To enable the cable modem on/off trap notification:
Step 1 Launch an xterm and execute:
/opt/AV/bin/av shell
Step 2 Change to /opt/AV/config/scripts.
Step 3 Execute:
./SetCmOnOff.pl ip-address-uBR read-comm-str write-comm-str interval-in-seconds
where interval-in-seconds is greater than 0.
Table 3-1 shows the traps supported for Cisco uBR7200 series universal broadband router and cable modem management.
| Trap | Description |
|---|---|
Cable modem on | Cable modem connected to a Cisco uBR7200 series universal broadband router turns on or off. |
ccCopy Completion | The notification is used to indicate that a config-copy operation to or from the agent has been completed. |
ciscoConfigManEvent | Notification of a Configuration Management event as recorded in the History Event Table. |
ciscoEnvMonShutdownNotification | A ciscoEnvMonShutdownNotification is sent if the environmental monitor detects a test point reaching a critical state and is about to initiate a shutdown. This notification contains no objects so that it may be encoded and sent in the shortest amount of time possible. Even so, management applications should not rely on receiving such a notification as it may not be sent before the shutdown completes. |
ciscoEnvMonVoltageNotification | A ciscoEnvMonVoltageNotification is sent if the voltage measured at a given test point is outside the normal range for the test point (that is, at the warning, critical, or shutdown stage). Since such a notification is usually generated before the shutdown state is reached, it can convey more data and has a better chance of being sent than does the ciscoEnvMonShutdownNotification. |
ciscoEnvMonTemperatureNotification | A ciscoEnvMonTemperatureNotification is sent if the temperature measured at a given test point is outside the normal range for the test point (that is, at the warning, critical, or shutdown stage). Because such a notification is usually generated before the shutdown state is reached, it can convey more data and has a better chance of being sent than does the ciscoEnvMonShutdownNotification. |
ciscoEnvMonFanNotification | A ciscoEnvMonFanNotification is sent if any one of the fans in the fan array (where extant) fails. Because such a notification is usually generated before the shutdown state is reached, it can convey more data and has a better chance of being sent than does the ciscoEnvMonShutdownNotification. |
ciscoEnvMonRedundantSupplyNotification | A ciscoEnvMonRedundantSupplyNotification is sent if the redundant power supply (where extant) fails. Because such a notification is usually generated before the shutdown state is reached, it can convey more data and has a better chance of being sent than does the ciscoEnvMonShutdownNotification. |
ciscoFlashCopyCompletionTrap | A ciscoFlashCopyCompletionTrap is sent at the completion of a Flash copy operation if such a trap was requested when the operation was initiated. |
Link up | The link between a Cisco uBR7200 series universal broadband router and a cable modem goes up or down. |
Cold start | A Cisco uBR7200 router is cold started, warm started, or reloaded. |
SNMP authentication failed | Community string settings between a management station and an SNMP-enabled device did not match. |
Cisco Cable Manager allows you to set thresholds on a Cisco uBR7200 series universal broadband router with specified polling intervals to generate alarm notification when a threshold level is exceeded. Thresholds can be set for the following Cisco Cable Manager attribute groups:
To launch the Threshold Manager, click the Threshold icon in the Launch Pad. For more detailed instructions on setting thresholds, refer to the Cisco EMF/EM documentation.
Cisco Cable Manager can optionally run with Cisco IP Manager so you can create configuration templates and configure Cisco uBR7200 series universal broadband routers in single or batch mode. The configuration templates contain a template body and template data. The template body contains attribute variables that are converted to Cisco IOS configuration files that can be downloaded to the routers. The template data is a matrix of devices identified by IP address and attribute variable values for each device.
Cisco Cable Manager enables you to:
Predefined templates for Cisco uBR7200 series universal broadband router configuration are included as part of the post-installation script in the Cable Manager package. These predefined templates are categorized in two parts:
Each predefined template uniquely identifies the subsection of configuration commands for Cisco uBR7200 series universal broadband routers. The predefined templates are stored in the Cisco IP Manager run time directory as part of the installation process. The Cable Operator can select a template and the associated configuration (Cisco IOS) commands are displayed on Template Config builder window.
Configuration updates can be scheduled to reload the device configurations at specified intervals using the Element Reload window.
To start Cisco IP Manager:
Step 1 Start the Cisco IP Manager application. Cisco IP Manager runs independent of Cisco Cable Manager.
Step 2 Enter the default login name and password. The default for both is admin.
Step 3 In the Service Control panel window, click Element Manager service.
Step 4 To create a new domain, click on the domain to display domain property window.
Step 5 Select NEM server from the list.
Step 6 At the NEM server page, enter the TFTP server and path name relative to /tftpboot directory, Telnet retry count and Timeout values. Click OK to set up the NEM server for the newly created domain.
Step 7 Right-click the mouse on the domain and select New. Then select the Element command on the submenu.
Step 8 Enter a name for the new Cisco uBR7200 series universal broadband router and click OK. This adds the Cisco uBR7200 series universal broadband router to the data tree in Element Manager window.
Step 9 Right-click on the newly added Cisco uBR7200 series universal broadband router and select Properties.
The Device Properties dialog will be displayed, with the Property tab selected.
Step 10 Select the Connection Method as Console (means Cisco IP Manager will communicate with this device console port through Communication Server). Enter the values for:
Step 11 Verify the connectivity.
Step 12 Click Template Manager service from the Service Control Panel window, select domain, uBR Element type and import the appropriate templates to view Configuration commands at Template Config Builder window.
Step 13 Enter the configuration value at the cell and download the configuration to the Cisco uBR7200 series universal broadband router. You can download the configuration to one or more devices.
Figure 3-3 shows a sample Cisco IP Manager screen with Cisco uBR7200 series universal broadband router domain and icons.
Cisco Cable Manager also allows you to specify and display the Cisco uBR7200 series universal broadband router configuration parameters for reference. These settings are required to use the Find/Ping modem feature, Flapping Modem report, and can be helpful to establish a Telnet session.
To specify configuration parameters for reference, select the desired Cisco uBR7200 series universal broadband router in an object map and from the right-click menu, select Modify Configuration Settings. The Modify Configuration Settings dialog box appears.

Cisco Cable Manager provides the following performance capabilities for Cisco uBR7200 series universal broadband routers and cable modems. Report data can be generated for all the routers deployed under a site, individual cable routers or individual cable modem. Report data can be exported in tab-delimited ASCII files. All reports can be run on-demand or on a scheduled basis.
Report data is available in predefined and customized reports. Predefined and customized report data is stored on a daily basis in /opt/AV/performance/[date] directories. If disk space becomes unavailable, these files may need to be archived to another location or deleted.
Predefined reports display a preset group of performance parameters for a selected Cisco uBR7200 series universal broadband router or a group of routers.
The following predefined reports are available for cable router performance:
To display a predefined performance report, select the desired object and from the right-click menu, select uBR Predefined Performance Report. The uBR Predefined Performance Report Date and Time dialog box appears. (See Figure 3-5.)
Specify the desired dates and times, click Save (check mark) in the tool bar, and click Run Report for the desired report. The uBR Power Level Report dialog box appears with the selected report data. (See Figure 3-6.)
Table 3-3 describes the Power Level report fields.

Cisco Cable Manager provides the following tools for troubleshooting Cisco uBR7200 series universal broadband routers and cable modems:
Cisco Cable Manager displays a flapping modem list to provide early notification of potential cable modem failure and lost connectivity.
A polled cable modem is considered intermittent or flapping when any of the following occurs:
Figure 3-22 shows the Flapping Modem List dialog box.
Table 3-23 describes the Flapping Modem List dialog box fields.
| Field | Description |
|---|---|
Max Size of Flap List | Maximum number of cable modems that can appear in the Flap list before the oldest data is overwritten with new data. |
Flap Aging Threshold | Interval in minutes during which the Flap list is refreshed. |
Flap Insertion Time | Timeout period in seconds for the cable modem registration process to complete. If the timeout period is reached before the registration process is complete, the cable modem is added to the Flap list. |
Current Size of Flap List | Number of cable modems currently listed in the Flap list. |
To modify the current Flap List settings, click Modify. To generate a Flap List, click Run Flap-List Report.
To find or ping a cable modem, select the desired group of Cisco uBR7200 universal broadband routers and from the right-click menu, select Find/Ping Cable Modem. The Find/Ping Cable Modem dialog box appears.
Figure 3-23 shows the Find/Ping Cable Modem dialog box.
Table 3-24 describes the Find/Ping Cable Modem dialog box fields.
| Field | Description |
Find | Displays the containment path and object location in Cisco Cable Manager. |
IP Ping | Verifies IP network connectivity between the Cisco uBR7200 series universal broadband router and the cable modem. The results are returned to Cisco Cable Manager. |
MAC Ping | Tests the connectivity between Cisco Cable Manager and the specified cable modem. |
To verify Cisco Cable Manager server performance and reliability, use the troubleshooting procedures described in this section.
If available disk space on the Cisco Cable Manager server is low or unavailable, verify that only the desired report data is stored on the server. Predefined and customized report data is stored on a daily basis in /opt/AV/performance/[date] directories. To free disk space, these files may need to be archived to another location or deleted.
This brings up a shell window that has all the necessary Cisco EMF paths set. Run av backup. This command will backup the databases under ${AVROOT}/db and locate them under ${AVROOT}/backup/ with a note on the date on which it was backed up.
To perform a Restore, enter the command av restore. This command prompts for the date in the form of <mm-dd-yyyy> and -d <db1 [db2 ...]> to represent the databases that need to be restored.
The CEMF provides for logging information via log files located under the ${AVROOT}/logs. Of all the log files, the file named cblCtrl.log and cblCtrl.old are of primary importance. These log files are ASCII file that contain all Cisco Cable Manager application specific log messages.
By default, DEBUG entries are not included in these log files. In order to see log messages of DEBUG severity (this includes all other severities), a change needs to be made to the loggercommon.include file located in the /opt/AV/config/init directory. By default the loggingLevelMask is set to 10. Changing this setting to 15 causes all DEBUG level messages to be logged.
The size of the cblCtrl.log file can also be controlled via the cblCtrl.ini file located in the /opt/AV/config/init directory. Add an entry in the logger section of cblCtrl.ini for the size of the log file specified in KBytes. Then stop and re-start CEMF.
An example of a section of the cblCtrl.ini for the logger section in order to specify a 5 MB cblCtrl.log file:
[logger]
#include "loggercommon.include"
loggingName = cblCtrl
maxLogfileSize = 5000
Whenever the cblCtrl.log file reaches it maximum size as specified in the control file, it is archived to a cblCtrl.old file and a new cblCtrl.log file is created.
The numerous other log files also available for troubleshooting. Log files are stored in the /opt/AV/logs directory.
From time to time, it is best to run the script listCores provided in ${AVROOT/bin (typically /opt/AV/bin). This report displays any core files affected by any malfunctioning processes. Whenever an affected core file is seen, please report it to Cisco customer support.
