Release Notes for Cisco DSL Manager NI-2 3.4.2

These release notes document caveats, new features, and updates that pertain to the Cisco Digital Subscriber Line Manager (CDM) application software. This release supports any Cisco 6015, 6100, 6130, 6160, or 6260 DSLAM chassis that has a network interface-version 2 (NI-2) card.

Note

CDM Release 3.4.2 can support 500 nodes (DSLAMs) and 30 operators logged on to the same network simultaneously if the server is set up according to the large site requirements (see the "Large Site Requirements" section). The server must be configured with 4 GB of RAM and four CPUs, and the Object Store database must be configured to use a striped RAW partition spread across at least four disk drives. The CDM server can support only one to three users. Any more users should be set up with one or more additional Cisco EMF client workstations. Future releases will support additional nodes and operators.

Note

When you install CDM Release 3.4.2, you must also install any necessary Cisco EMF patches. For more information about which patches you should install, see the Readme.txt file that is included with the software package located on the following URL:
http://www.cisco.com/cgi-bin/tablebuild.pl/dsl-mgr
To download and install Cisco EMF and any related patches, refer to the Cisco Element Management Framework Installation and Administration Guide. You must install Cisco EMF before you install CDM.

System Requirements

You can deploy CDM in a number of different configurations, from a single hardware system to a multisite distributed management system. Use Sun Solaris or Sun SPARC hardware with Solaris Release 2.8 . Specifications are given in the following sections.

Small Site Requirements

In the context of CDM Release 3.4.2, a small site is one that manages no more than 25 to 50 DSLAMs. As you add more DSLAMs, memory requirements increase. You might be able to manage a few more DSLAMs than you are already managing by increasing the memory and swap space on your computer. The CDM server requires about 2 GB RAM when it starts up. If your computer has less than 2 GB RAM, processes are swapped out to disk, and most processes run more slowly. Always set up the swap space to be at least 2 to 3 times the amount of memory on the computer.

We recommend that you have no more than one to three users on the CDM server computer. If you need to support more users, set up a separate computer with the CDM client software. A small site configuration that has a client and a server computer should be able to support from six to eight users.

Computer specifications for a small site are described in the following sections.

Minimum System Requirements for a Small Site

Recommended System Configuration for a Small Site

Large Site Requirements

In the context of CDM Release 3.4.2, a large site is one that manages more than 50 DSLAMs. As you add more DSLAMs, the memory requirements increase. You might be able to manage a few more DSLAMs if you increase the memory and swap space on your computer. The CDM server requires about 2 GB RAM when it starts up. If your computer has less memory, some processes are swapped out to disk, and most processes run more slowly. You should always set up the swap space to be at least 2 to 3 times the amount of memory on the computer.

It is very important that you set up the Object Store database on RAW file systems and across as many disk drives as you can afford. The more disk drives you use, the better the database will perform. See the Installation Notes for the Cisco DSL Manager, Release 3.4.2 for more detailed information and instructions about this topic.

We recommend that you have no more than one to three users on the CDM server computer. If you need to support more users, set up a separate computer that is running the CDM Client software.

The computer specifications for a large site are described in the following sections.

Minimum System Requirements for a Large Site

Recommended System Configuration for a Large Site

Client Workstation Requirements

You can have multiple client computers connected to the CDM server manager computer. The more CPU power you have on the client computer, the more client sessions you can support.

In large deployments that have client-server configurations, We recommend the following hardware specifications for typical client deployments:

Note

You can use smaller monitors. We recommend the 17 to 21-inch monitors because they provide the best view of the CDM GUI windows.

Cisco IOS Compatibility

CDM Release 3.4.2 NI-2 manages any DSLAM running IOS 12.2(7) , 12,2(10) and 12.2(12), including their functions and hardware features.

For all CDM Release 3.4.2 features to operate correctly, you must have Cisco IOS Release 12.2(7) or later installed..

Caveats for CDM NI-2 Release 3.4.2

The following sections list open and resolved caveats for the Cisco Digital Subscriber Line Manager, NI-2 version, Release 3.4.2.2.

Open Caveats for CDM NI-2 Release 3.4.2

Table 2 NI-2 Open Caveats for CDM Release 3.4.2
DDTS Entry	Description
CSCdr17338	In the Chassis Configuration window, some attributes appear that are invalid for Cisco DSLAM devices. These attributes are not present in the ENTITY MIB¹; you cannot read these attributes from or set them to the device. Impact: These attributes display as ERROR in the window. Workaround: None.
CSCdr48507	CDM displays the same icons for different chassis, line cards, and interfaces. With CDM Release 3.2, only the 6160 chassis, SDSL line card, and SDSL interface objects display icons that are specific to those object types. Impact: You cannot identify the type of chassis and card by looking only at the icon. Workaround: None.
CSCdr52597	If the config-register parameter in Cisco IOS software is set to 0x0, and you choose "reset device using new image—yes," this fails to result in a DSLAM reset with newly-downloaded Cisco IOS image. Impact: You cannot successfully reset the DSLAM with the new Cisco IOS image. Workaround: Access the Cisco IOS prompt and set the config-register as follows: `>` # conf term (config)> # config-register 0x2104 The reset device from CDM now works.
CSCdr60691	If you attempt to delete a preprovisioned card using CDM, you cannot complete the task. A deletion using CDM should result in the card being removed from CDM as well as from the DSLAM. CDM currently only removes the card from CDM. Impact: The deleted card is not removed from the DSLAM IOS configuration. The deleted card initially disappears from the CDM GUI², but the card reappears when CDM performs subrack discovery (either by user request or through a trap-initiated discovery) on that DSLAM. Workaround: Delete the affected card from the DSLAM by using the CLI³ after you delete the card through CDM.
CSCdr78199	You cannot create an SPVC⁴ with a non-Cisco EMF endpoint. Impact: You cannot create an SPVC with a non-Cisco EMF endpoint. Workaround: Use the IOS CLI to create an SPVC with a non-Cisco EMF endpoint.
CSCdr89318	If you initiate a Telnet session in CDM, the session does not close when you exit CDM. Impact: The Telnet session does not close automatically when you close the Map Viewer window and exit CDM. Workaround: To close the Telnet session, enter the following command: > exit
CSCdr93175	After CDM deletes any line card, the node does not consider the card preprovisioned. When you remove the card and reinsert it into any slot, CDM does not detect its presence even though the node sent a module insert trap. Impact: Module discovery does not automatically initiate after the line card is reinserted into the DSLAM. Workaround: Provision the line card instead of allowing the DSLAM to automatically provision the card after a module insert trap.
CSCds14977	CDM does not update the chassis list. Impact: You cannot access a recently added or modified DSLAM. Workaround: Close the Chassis Configuration window and reopen it to refresh the chassis list.
CSCds45031	You cannot use the symbol "/" to name a PVC connection. Impact: CDM does not accept the use of "/" as part of a PVC connection name. Workaround: Do not use blank spaces or the symbols "&" or "/" when you naming PVC connections.
CSCds55492	CDM cannot manage up to 1500 DSLAMs as specified by scalability requirements. The current limit is 130 DSLAMs. Impact: As above. Workaround: None. There is a plan to significantly improve scalability in a future release of CDM and Cisco EMF.
CSCds89708	The CDM backup failure message indicates the incorrect directory for the backup file. Impact: CDM cannot complete the restore operation. Workaround: Follow these steps: 1. Log on to the server and go to the TFTPboot directory. 2. Create a file with the address of the IOS host. For example: `touch IOSHost172.21.178.12` 3. Grant read/write permissions to the file. For example: `chmod a+rw IOSHost172.21.178.12` 4. Perform the backup operation. Here is an example of the message that displays: `Manager and the TFTP server are differentTFTP Service is not runningtftp host is 171.69.161.74!!!5344 bytes copied in 1.246 secs (5344 bytes/sec)NMS-DC6`
CSCds91960	Status messages show no value for the Frame Relay. Impact: None. Workaround: None.
CSCdt24869	CDM does not perform range checking for profile RxTx parameters. Impact: Incorrect input values cause an error when you try to apply the profile. Workaround: Input the correct values.
CSCdu02994	If you disconnect the OC-3 link on an active NI-2 card, an alarm is raised. However, this alarm is not mapped to the NI-2 card; it is been mapped to the chassis and to an IDSL card present in the DSLAM. Impact: You might miss the event. Workaround: None.
CSCdu15532	If the network is continually sending link up or down traps for ports on an interface and, at the same time, a user is attempting to stop or back up Cisco EMF, Cisco EMF cannot suspend the alarms. Impact: You cannot stop or back up Cisco EMF. Workaround: Disable traps for the port that is sending the alarms before you stop Cisco EMF or before you perform a backup on Cisco EMF. To disable the link up and down traps on a port, follow these steps: 1. From the left side of the CDM Map Viewer window, right-click the port whose traps you want to disable to access the object menu. 2. Choose Cisco DSL Manager > Physical > Interface > Generic > Configuration to open the Interface Configuration window. 3. Use the down arrow in the Link Up/Down Trap Enable field to select disabled. 4. Click the Save icon in the toolbar for this change to take effect. After you have completed the backup and have restarted Cisco EMF, you need to reset the Link Up/Down Trap Enable field to enabled.
CSCdu59045	The Frame Relay controller should inform the synchronization framework of the completion of auto synchronization and upload of connections and profiles. Impact: Frame Relay synchronization is not streamlined. Workaround: None. This does not impact the user with this release.
CSCdv24320	The list of profiles that you can apply to a connection shows FR, PPP and ATM—all three types of QoS profiles. Impact: If you choose a connection type that is not supported for a selected interface, no error message displays to explain why the connection fails. Workaround: You must make sure that you apply the correct profile to the correct connection type.
CSCdv27754	The Frame Relay Connection Manager sometimes does not respond to a lock request. Impact: You cannot back up the system. Workaround: Restart Cisco EMF and run backup the command again. Note This DDTS is postponed until a future release of CDM.
CSCdw79979	This caveat has two parts: 1. The Interface Summary window and the Apply XDSL Profile window display the Subscriber ID in the ATM layer rather than the physical layer. When the you set the subscriber ID on the physical layer rather than on the ATM layer, the Subscriber ID field displays nothing in these windows. 2. On the Chassis Summary window, the Subscriber ID field does not display the subscriber name that you entered when you created the PVC. Impact: 1. The subscriber ID does not display correctly on the Interface Summary window or on the Apply XDSL Profile window when the you use the IOS command dsl subscriber subscribername to set the subscriber ID. The IOS command sets the subscriber ID on physical layer. 2. The subscriber ID that is used to create the PVC creation is not saved to the DSLAM. Workaround: 1. You can use the IOS command description to set the subscriber name on the ATM layer and the subscriber name will display in the Interface Summary window and the Apply XDSL Profile window. 2. None.
CSCdw83772	When you uninstall CDM, errors are generated even though the end report states that the uninstall was successful. Impact: You might get conflicting information about the status of an uninstall procedure. Workaround: None.
CSCdw84309	The Action Report dialog displays "Actual Failure" when you create an SPVC even if there is no error. Impact: As above. Workaround: None.
CSCdw87295	A subtend discovery discovers the DSLAM with an old IP address after the IP address has been changed. Impact: The Subtend topology view does not have the correct DSLAM information when the IP address on the DSLAM changes. Workaround: Use the IOS Reload command on the DSLAM before you discover the subtend topology.
CSCdw92429	After you have made a change to an entity in the DSLAM (such as pulled a line card), subrack discovery might take longer than two to three minutes if the system is busy. Impact: It might take longer for CDM to synchronize with the DSLAM. Workaround: Enable SNMP traps in the DSLAM by adding the CDM server as the SNMP host in the device. Then SNMP traps will be sent to CDM server and when it receives the traps, subrack discovery is triggered.
CSCdx06844	If you download an IOS image during an extreme system load, on rare occasions the DSLAM might appear in normal state while the modules remain in a download state. Impact: Modules appear to still be in download state. Workaround: Re-open the Map Viewer window.
CSCdx06861	When you are simultaneously creating and deleting an unusually high number of objects (for example, deleting and re-adding hundreds of PVCs) in a short time frame, deploying an SPVC might fail. Impact: The SPVC is not created in the DSLAM; it is only created in CDM. Workaround: Delete and re-create the SPVC in CDM.
CSCdx07840	After you enter the cemf stop command, the Cisco EMF system does not shut down. Impact: Occasionally, when the Cisco EMF system is under a heavy load (such as when you are bulk commissioning 250 chassis), cemf -stop does not stop the system until the system has stabilized (that is, the bulk operation has completed). Workaround: If you are running a system operation that uses a lot of memory, wait until the operation concludes to stop Cisco EMF.
CSCdx07887	If you try to restore a Cisco EMF database, in which the original backup contains a large number of DSLAMs (for example, over 100) that are in a commissioning state, the restore action might fail. Impact: The restore might fail. However, it is unusual to run a backup while the system is in the process of a large network change. Workaround: You should wait to run system backups after large changes to the system are completed.
CSCea00441	CEMF base directory (i.e. where CEMF is installed) is hardcoded to /var/cemf in one of the config files (cdmControllerUserData.ini) Impact : Performance polling will not be done in cdmController. If alarms are not processed, then state transistion will fail. Also, finding IMA trunk will fail. Workaround : Create a symbolic link in /var directory to point to the CEMF base directory, for example if the installed path is /opt/cemf then create the link in /var directory to point to /opt/cemf. If CEMF has already been started then cdmController needs to be restarted to get the config file parsed. Example: `cd /varln -s /opt/cemf /var/cemf` If CEMF has been already started, then execute the following commands `cd /opt/cemf/bin./cemf shell./sysmgrClient -k cdmController./sysmgrClient -x cdmController`
CSCin05111	When you delete a preprovisioned line card from CDM, a confirmation dialog does not open to inform you that the card is being deleted. Impact: You are not sure whether CDM is deleting the line card. Workaround: None.
CSCin05629	If you schedule a download/backup operation for a time that is up to 9 minutes in the past from the regularly scheduled time, the download/backup operation starts even though it should not. Impact: The scheduled download/backup is invoked even though the scheduled time was 9 minutes earlier than the current time. Workaround: None.
CSCuk24676	The Frame Relay connection manager uses its own upload window to synchronize with the DSLAM. Impact: The synchronization request from the synchronization framework does not include having the Frame Relay connection manager synchronize with the DSLAM. Workaround: When Frame Relay is available on the CDM GUI, you will be able to request the Frame Relay connection manager and have it synchronize its data with the DSLAM. Note Resolution of this DDTS is postponed until a future release of CDM.
CSCuk29916	If you open the Deployment Wizard window from a specific port to deploy a PVC, the Source and Destination port fields are blank in the Deployment Wizard window. Impact: You assume the source or destination port field will display the port from which you opened the Deployment Wizard window to deploy the PVC, but it does not. Workaround: You need to specify the source or destination port when you deploy a PVC in the Object Selector window.
CSCuk32431	The XDSL controller might experience a memory leak. Impact: The XDSL controller uses more memory while it is running. Workaround: When you notice that the XDSL controller is using too much memory, kill the XDSL controller then restart it. Use the following commands: /opt/cemf/bin/cemf shell /opt/cemf/bin/cemf -k XDSLCtrl /opt/cemf/bin/cemf -x XDSLCtrl

Resolved Caveats for CDM NI-2 Release 3.4.2

Table 3 NI-2 Resolved Caveats in Release 3.4.2
DDTS Entry	Description
CSCdr12196	You can manually commission and decommission every object in CDM. Impact: Being able to commission and decommission any object might be confusing. Workaround: Always click a chassis object and open the Chassis Configuration window to commission or decommission a chassis.
CSCdr17304	In the Management Information window, you can set the System Name, System Contact, and System Location fields for the current DSLAM configuration. However, the software does not save these values to the startup configuration. Impact: If you reboot the DSLAM, the changes to current running configuration are lost. Workaround: Periodically save the current running configuration to the startup configuration if you want the software to retain these changes.
CSCdr17784	In the Module Fault Management window, the Operational status attribute does not display a value for a DMT card in a chassis. This attribute is not valid for a DMT card. Impact: As above. Workaround: None.
CSCdr18302	In the Interface Status window, the Type attribute incorrectly displays the value for a DMT card. Impact: The DMT card configuration displays incorrectly. Workaround: None.
CSCdr25471	When creating a new profile, CDM adds the profile to the object list in the left side of the relevant Profile window. The newly added profile is not automatically highlighted, or selected. Impact: You must select the newly created profile by clicking it to highlight this profile; it is not automatically highlighted. Workaround: Click the newly created profile to highlight or select it.
CSCdr25956	When an operator changes the connection mode from Digital Off-Hook to Direct Connect, or vice versa, CDM does not reset the DSLAM alarms. Impact: You cannot identify the outstanding alarms against a DSLAM after changing the connection mode from Digital Off-Hook to Direct Connect, or vice versa. Workaround: After you change the connection mode of a DSLAM, delete that DSLAM from CDM and then redeploy it. Deleting a DSLAM removes all outstanding alarms against it. After redeploying the DSLAM, you can identify any new outstanding alarms that the DSLAM generates.
CSCdr31253	The chassis gif, dialog, and menu selections all refer to a DSLAM6100 MUX chassis regardless of whether the managed element is a 6100 MUX chassis or a 6130 MUX chassis. Impact: It is difficult to determine whether the MUX chassis is a 6100 or 6130 chassis based on the chassis bitmap, dialog, or menu chassis references. Workaround: To determine the proper MUX chassis version, look at the Chassis Rev field in the MUX Chassis Configuration window. If the chassis revision is 5 or less, the MUX chassis is 6100. If the chassis revision is greater than 5, the chassis is 6130.
CSCdr43095	If the avload.log file is full, the IOS image download fails. Impact: Performing an IOS image download fails if the file system is full. Workaround: You can clear the flash memory at the node and then re-initiate the IOS image download procedure.
CSCdr43105	You cannot cancel or edit a scheduled Cisco IOS image download. Impact: You might decide you do not want to continue the download process, or you might want to edit the process, but you cannot do either. Workaround: If you want to cancel the download, stop Cisco EMF at the time of download.
CSCdr51495	The Cisco IOS image download fails if you launch it from the NI-2 card. Impact: You cannot download the IOS image. Workaround: Launch the IOS image download process from the site or chassis objects.
CSCdr52395	Image Download status only displays the status of the previous download. Impact: This attribute does not show status of a download in progress. Workaround: View the status of a download in progress in the IOS image download window.
CSCdr52428	After you enter values in the fields in the IOS Image Download window, you must click the Save icon in the toolbar to save these values. Impact: If you do not click Save, CDM does not receive the values that you selected for downloading. Workaround: None.
CSCdr53332	Initially all of the Interface Configuration windows indicate that a profile was applied, but the profile was not really applied. Impact: The Configuration window displays information when it is initially deployed even though a blank is appropriate when there is no information assigned to the interface. The information that appears is residual, arising from a previous selection or from a list of defaults. Workaround: None.
CSCdr55774	If you try to apply a profile and you have not selected a specific profile (such as an ADSL or DMT profile), the window stops responding and the process fails. Impact: You cannot apply a profile. Workaround: When you apply a profile, first make sure you have selected a profile to apply.
CSCdr57494	The SDSL Module Inventory window contains empty fields; this is because the values for these fields are not set in Cisco IOS. Impact: None. Workaround: None.
CSCdr60092	In the Syslog Messages window, when you change the Maximum Table Entries field, the Syslog Messages area fails to automatically update when you click Save. Impact: You saved changes, but it appears that CDM did not save them. Workaround: Close the Syslog Messages window, and then reopen it to view the changes.
CSCdr61147	You should not be able to edit the SNMP¹ Version field in the Deployment Wizard. Impact: If you change the SNMP version, the deployment process could fail. Workaround: Do not edit the SNMP Version field.
CSCdr61148	SNMP Community strings that you enter in the Deployment Wizard window always appear in the SNMP V2 fields of the SNMP Management window, no matter which version of SNMP you select. Impact: As above. Workaround: None.
CSCdr61855	In the PVC/SPVC Deployment Wizard, you are prompted to choose the PVC Source and Destination ports. Both fields in which this selection takes place have labels that read Component Managed instead of Source Port and Destination port. Impact: As above. Workaround: Ensure that the two managed components are unique and represent the source and destination.
CSCdr63664	CDM displays a DSLAM in an errored state for a period of time after an operator resets the system controller in the DSLAM. Impact: You must wait several minutes after performing a system controller reset before CDM indicates that the managed element is in a normal state. Workaround: None.
CSCdr65868	Some OC-3 and DS3 alarm states supersede other alarm states and render them as unknown. CDM reports all alarm states as either present or absent, and suppressed alarms do not appear as suppressed. Impact: Although some alarm states might appear as normal, the true states are suppressed or unknown. Workaround: None.
CSCdr67252	If you deploy an incorrect type of NI-2 card on an NI-2 card that is physically present in a DSLAM (for example, an OC-3 on top of a DS3) in a decommissioned chassis and then commission that chassis, CDM incorrectly discovers the physical NI-2 card. CDM discovers the incorrect NI-2 card as a preprovisioned type with physically present interfaces marked normal and discovers the remaining interfaces as preprovisioned. Impact: The NI-2 object will be in an inconsistent state. Workaround: Delete and then redeploy the DSLAM.
CSCdr71375	In the Deployment Wizard—Views window, CDM automatically enters data into the first and second fields, for example when you are deploying a PVC. Impact: When you select an object for the first field, CDM automatically generates the second field with that object. Workaround: Enter text in the top field first, and then enter a new value for the second field to replace the value that CDM automatically generates.
CSCdr75903	The GUI (in particular the IMA² view) does not reflect the correct hierarchy after CDM reparents the IMA link. Impact: The hierarchy view that displays does not reflect the current hierarchy that is on the DSLAM. Workaround: Exit the Map Viewer window and reopen it. The hierarchy view refreshes with the correct IMA parenting.
CSCdr78715	You cannot view port objects in the CDM Manager view. Impact: As above. Workaround: You can view and access all services associated with a port from the site and chassis objects.
CSCdr81466	If you choose Tools > Performance Manager from an SDSL, DMT, or CAP interface, the following message displays: `This object has no attributes which are being monitored.` Impact: You cannot see performance attributes change at the appropriate time intervals. Workaround: None.
CSCdr82664	You cannot view data in the Interface Performance window for DMT, CAP, or SDSL interfaces. Impact: As above. Workaround: None.
CSCdr83759	IOS fails to set FlexiDMT values for the current upstream codeword size, current downstream codeword size, and current FEC size. Impact: These FlexiDMT Interface Status values are not updated in CDM. Workaround: None.
CSCdr85143	When the Create PVC process fails, the error messages are difficult to understand. Impact: As above. Workaround: None.
CSCdr85965	If you preprovision a slot in a Cisco 6130 DSLAM for a FlexiDMT card and insert a 2xCAP card, the SysLog does not generate an error message. Impact: CDM does not inform you if there has been a card mismatch in a Cisco 6130 DSLAM. Workaround: None.
CSCdr86598	When you are deploying a Cisco 6160 DSLAM, major (orange) alarms display on any NI-2 cards, even if no problem exists. Impact: Falsely displayed alarms can be misleading. Workaround: None.
CSCdr86966	After receiving a commissioning failure alert from CDM, you cannot decommission the DSLAM. Impact: You must use an alternate method to remove the chassis. Workaround: Open the configuration window, decommission the chassis (although it is not commissioned), and choose Deployment > Delete Objects from the ComponentManaged view.
CSCdr87046	CDM allows you to enter or deploy a site without specifying a name for that site. Impact: A deployed site could have no name, resulting in confusion. Workaround: Always enter a unique site name for each management server.
CSCdr88804	The SDSL Interface selection box within the SDSL Interface Configuration window does not function correctly. The selection box displays all SDSL interfaces that populate the chassis regardless of the selected module. Impact: You cannot determine which SDSL interface should be used with a selected module. Workaround: None.
CSCdr90480	CDM does not always process SNMP traps. It is unknown whether the traps are dropped at the DSLAM, in the network, or in CDM. Impact: Occasionally, the Event Browser window for the DSLAM fails to display events for that DSLAM. These status events are typically recognized when another trap is processed from the same DSLAM. Workaround: Confirm the status of a module or interface using the Object Status field at the bottom of most GUI windows.
CSCdr90930	When you try to backup a configuration for the first time using the Configuration Backup/Restore window, CDM fails to create a new file on the TFTP server. Impact: You must create an empty file and set its permissions so that it is writable. Workaround: Complete these steps: 1. Try to back up the configuration; the correct filename displays in the Status field of the Configuration Backup/Restore window. 2. Telnet to the TFTP server. 3. In the root directory use the touch command on the file. 4. Enter the command chmod 777 <filename>. 5. Back up the configuration data to the file.
CSCdr90944	Periodically, the content of the Edit menu in the CAP Interface Status and DMT Interface Status windows is not dimmed as it should be, because the Edit menu functions are not valid in these windows. Impact: You might believe that the Edit menu functions are valid. In fact, the Edit menu items should be dimmed; do not use them. Workaround: None.
CSCdr91628	If you decommission a DSLAM, the PVCs display as being disconnected and decommissioned. In fact, when you decommission a DSLAM, the PVCs remain connected. When you recommission the DSLAM, CDM does not recommission PVCs. Impact: If you decommission or recommission a DSLAM, the active PVCs remain in a disconnected and decommissioned state after recommissioning. CDM should depict the active PVCs as being connected and commissioned after CDM recommissions the DSLAM. Workaround: After you recommission a DSLAM, you must recommission each active PVC. You can recommission the PVC by selecting the PVC in the ATM Connection Management window and clicking Commission.
CSCdr93836	The Command Log window is not consistent with the SysLog Messages window. When you click Save in the Command Log window, the Save icon is not dimmed as it should be after you click Save. Impact: It might appear that the Save operation failed. Workaround: None.
CSCdr93872	When you refresh the Command Log window, the value that you specify for the Maximum Table Entries field returns to the default value of 10 rather than refreshing the contents of the Command Log window. Impact: The Maximum Table Entries field is reset to default and does not retain the specified value. Workaround: None.
CSCdr94401	When the power to the CPE is disconnected, the CiscoSDSLFunctionality, CiscoCAPFunctionality, and CiscoDMTFunctionality status displays as "errored." Impact: None. Workaround: None.
CSCds00606	The following line card support caveats relate to specific DSLAM types: •The Cisco 6100 DSLAM chassis supports only the 4xCAP/DMT2 Flexi line card. However, DMT and DMTI display as choices. •The Cisco 6160 DSLAM chassis supports only the 8xDMT2 and 4xFlexi DMT2 line cards. However, DMT and DMTI display as choices. •The Cisco 6260 DSLAM chassis supports only the 4xDMT2 line card. However, DMT and DMTI display as choices. Impact: You might attempt to deploy a line card that the DSLAM does not support. Workaround: Deploy only line cards that the chassis supports.
CSCds04370	The IMA View fails to display generic objects such as sites and its own hierarchy view. As a result, the IMA view does not support redundant NI-1 or NI-2 cards if the names are not unique between the two ports of the redundant card. Impact: The IMA view does not support redundant NI-1 or NI-2 cards if the names are not unique between the two ports of the redundant card. Workaround: None.
CSCds04629	This caveat pertains to the Cisco 6015 DSLAM. CDM does not allow you to reparent one or more objects from the componentManaged hierarchy view. Impact: The componentManaged view does not reflect object parents. Workaround: You need to perform IMA reparenting only from the IMA hierarchy view. Also, for best results, perform subtending reparenting from the Subtend hierarchy view. You can perform all other types of reparenting from either the physical hierarchy view or the cdmManager hierarchy view. The componentManaged view is a display-only view; launching reparenting operations is not part of its functionality.
CSCds04684	After you preprovision a Flexi line card (either CAP or DMT) and then physically insert a Flexi line card into a 6100 DSLAM, the card appears in the Map Viewer window on one server, but not on the other. Impact: The card appears in the Map Viewer window on one server, but not on the other. Workaround: Decommission the chassis that does not display the card and then recommission it. CDM discovers the line card.
CSCds04685	Occasionally, if IOS preprovisions a Flexi/DMT card, CDM reports it as a Flexi/CAP card. Impact: As above. Workaround: None.
CSCds07500	The ADSL Status window does not display data for CAP modules. Impact: As above. Workaround: None.
CSCds08531	Autodiscovery is limited to the number of IP addresses allowed by the subnet mask for the gateway to which the node is connected. Impact: None. Workaround: If the subnet mask is 255.255.255.192 for example, the autodiscovery process detects nodes with 59 IP addresses. Therefore, CDM would have to autodiscover n number of IP addresses until the entire range is discovered.
CSCds12307	CDM allows the creation of a FlexiCAP profile without the availability of CPE Signature data. Impact: A FlexiCAP profile that has no CPE signature data impacts security. Workaround: None.
CSCds14939	When you open the Subtend Configuration window, the top list box displays the chassis and the lower list box displays the NI ports for that chassis. Frequently the lower list box displays all of the ports for all of the DSLAMS that CDM is managing rather than just those that pertain to the chassis that is highlighted in the top list box. Impact: You might not be able to determine which port is associated with which DSLAM when you are performing either a Connect or a Disconnect. Workaround: None.
CSCds15534	You cannot upload SDSL profiles using CDM 3.2. Impact: As above. Workaround: None.
CSCds16451	When you configure a hardware subtend and select the Subtend Configuration, you must perform an Update or Discover so that the subtend/trunk interfaces are configured. After updating, however, the Subtend Configuration window displays an incorrect Interface Type and neighborIPAddress. Impact: The incorrect Interface Type and neighborIPAddress display after you configure a subtend for hardware. Workaround: Select a new port to refresh the interface type and neighbor IP address.
CSCds16674	Connecting in the ATM Connections Management window fails due to script error. Impact: You cannot achieve an ATM connection in the ATM Connections Management window. Workaround: None.
CSCds20871	CDM object type files and binary names reference objects as Version 3.0, although they are Version 3.2. Impact: As above. Workaround: None.
CSCds22836	After you apply a QoS category UBR³+ profile to a PVC or an SPVC, the last apply profile status field in the ATM QoS Profiles Management window displays the following message: `Values were not in the range for the following params(s): Value supplied: UBR+ QoS Category must be any one of these: ubr, vbr-nrt, vbr-rt, cbr, abr Profile Application failed` Impact: You must know all of the appropriate values and interdependencies. Workaround: Use the IOS CLI to create QoS category UBR+ profile.
CSCds23563	The ATM Connection Manager terminates when you try to apply QoS profiles if there are no profiles. Impact: As above. Workaround: None.
CSCds25160	Manual deployment of NI-2 cards in a Cisco 6160 chassis fails. When CDM commissions the NI-2 card, the card enters a discoverylostcomm state. Impact: You cannot access a commissioned NI-2 card in this state. Workaround: None.
CSCds32699	If a preprovisioned card differs from the physically present card and the preprovisioned card is deleted, CDM does not perform subrack discovery for the actual card present. Impact: CDM does not perform continuous polling to determine the cards present. CDM does not discover a card that is physically present in a chassis. CDM performs the discovery and subrack discovery only during commissioning. Workaround: Decommission the chassis and commission it again. CDM does a subrack discovery on the physically present card.
CSCds35865	No default values display in the ATM Qos Profile window. Impact: Incorrectly entered values could affect provisioning. Workaround: See the Cisco DSL Manager 6015, 6100/6130, 6160, or 6260 user guide for the correct PCR values to enter.
CSCds35872	CDM gives no error message if you enter an invalid value for PCR⁴ in the ATM QoS Profile window. Impact: Using an invalid PCR value could affect provisioning and usability of the ATM connection. Workaround: See the Cisco DSL Manager 6015, 6100/6130, 6160, or 6260 user guide for the correct PCR values to enter.
CSCds35876	The cell rate fields in the ATM QoS Profile window incorrectly ask for values in cells/second. The correct rate is kbps. Additionally, the CDVT field incorrectly asks for a value of cell times. The correct unit is microseconds. Impact: The use of incorrect units causes confusion about actual rates supported by the connection. Workaround: You might have to perform unit conversions to determine the exact rates supported.
CSCds35942	You cannot delete a profile from the Edit menu option. Impact: As above. Workaround: Follow these steps: 1. Right-click the profile you want to delete. 2. Select Deployment > Delete Object.
CSCds50188	When you open the Map Viewer window, the name at the top of the hierarchy view in the left side of the window displays as "C61xxChassisView". It should display as "C6100ChassisView." Impact: The name of the chassis view in the left side of the Map Viewer window is incorrect. Workaround: None.
CSCds50272	After you create two PVCs on a FlexiCAP card for the Cisco 6015 DSLAM, apply the QoS profile to each PVC, and attempt to perform a cross connection for both PVCs simultaneously, the ATM connections process crashes when you click Connect in the ATM Connections Management window. Impact: You cannot perform a cross-connection for more than one QoS-profiled PVC at a time. Workaround: Connect only one PVC at a time.
CSCds56553	After you apply a QoS profile in the QoS Profile Configuration window, a dialog window indicates that the profile was rolled down to the node successfully. However, the QoS profile does not roll down to the node. Impact: CDM incorrectly displays a message indicating successful QoS profile application. Workaround: Always use IOS to set a QoS profile.
CSCds57961	An error message appears prematurely while you are changing the FlexiCard configuration from DMT to CAP (or vice-versa) when CDM is actually continuing to configure the line card in the background. Impact: CDM misinforms you that an error has occurred during the reconfiguration of a FlexiCard. Workaround: After approximately 3 minutes (4 minutes total), the card reappears with changed functionality.
CSCds57987	You cannot add a site under the physical component from classpallet. Impact: The site is not created. Workaround: None.
CSCds60987	When you upload subtend PVCs from a child chassis, the ATM Connection Manager core dumps and the subtend PVCs are not successfully uploaded. Impact: You cannot successfully upload subtend PVCs. Workaround: This problem occurs when there are PVCs with no corresponding VCLs. For CDM to work properly, use IOS to remove the PVCs whose VCI values are set to 0. An example follows: `node# show atm vc and note the PVCs with VCI=0node# conf t(config)# interface atm x/y(config-if)# no atm pvc <vpi> 0remove all the PVCs with VCI=0(config-if)# end# write mem`
CSCds73618	The status icon in the ADSL Interface Status window does not show any status. Impact: As above. Workaround: None.
CSCds79995	When you select the time filter between Previous Time and Now in the 8xDMT Interface Performance window and click Refresh, an error message displays "The start date and time must precede the end date and time." Impact: As above. Workaround: None.
CSCds80032	In the Performance window for the 8xDMT interface, the line chart does not draw data (ADSL-LINE-MIB.adslAturIntervalLofs) for the entire filtered period. Only data for the first 15 minutes displays. Impact: As above. Workaround: None.
CSCds81978	No performance data displays for the filtered period that contains traffic in the Performance window for the 8xDMT interface. Impact: As above. Workaround: None.
CSCds83037	DSLAM objects in CDM are green when DSLAM experiences a loss of communication. Further analysis shows •The chassis does not generate a loss of communication alarm when changing state. •The OSI⁵ State mapping for loss of communication is identical to the OSI State for decommissioning. Impact: CDM does not detect a loss of communication in the DSLAM. Workaround: None.
CSCds83467	A core dump occurs when you enter a new SDSL profile. Impact: As above. Workaround: Enter and exit the SDSL Profile window twice. The newly created SDSL profile appears in the Component Managed view or in the Apply Profile window drop down list and a second core dump occurs.
CSCds85466	When you apply a QoS profile to a PVC, the profile indicates it has been applied but the parameters are not changed. Impact: You cannot apply a QoS profile. Workaround: None.
CSCds86098	When two or more users perform basic system tasks, the objectServer process consumes almost all of the CPU. This usually occurs during the first hour of usage. Impact: The system becomes sluggish or gives slow performance. Occasionally, the system fails. Workaround: None.
CSCds86352	After you successfully apply a QoS profile, you receive an error message from CDM if you attempt to apply a second QoS profile. The message states that the profile was applied but the RxTx parameters were not updated. Impact: You might unintentionally cause CDM to use incorrect parameters to update the second profile. Workaround: Click the refresh icon when the RxTx parameters display for the first profile. This action updates the screen with the new values.
CSCds86658	CDM cannot retrieve performance data for a FlexiCap interface. Impact: As above. Workaround: None.
CSCdt00782	When CDM performs system backups, it names the files in the backup directory with a number corresponding to the day of the week that the backup occurs. Sunday is 0, Monday is 1, and Saturday is 6. If the current version of CDM performs backups on any day except Sunday (0), a problem occurs with the restore function; specifically, the restore function always looks for day zero (0). Thus, the restore function fails if the backup file is named with a number other than zero (0). Impact: The CDM restore function fails if the backup is performed on a day other than Sunday (0). Workaround: Open a terminal window and enter the following commands: mv day6.1 day0.1 This command renames day6.1 to day0.1 mv day6.config day0.config This command renames day6.config to day0.config. cemf restore -t {dateofdirectory} This command begins another file restoration. For example, if the date of restoration is December 10, 2000, you enter: cemf restore -t 12-10-2000
CSCdt26995	You cannot change the two fields, profile description and profile type, of an uploaded profile, but when you apply the profile to the ports, these two fields remain unchanged. Impact: None. Workaround: None.
CSCdt31760	Sometimes a problem occurs in which CDM stops processing the alarms sent for various traps. The alarms are apparent on the physical chassis or through IOS, but not in the CDM GUI. Impact: You do not see the alarms in CDM, and therefore you are unaware of any problems that are occurring in the network. Workaround: When you notice the alarms on the physical chassis or through IOS, stop and restart Cisco EMF.
CSCdt38136	CDM does not check to verify whether an illegal baud rate value has been saved to CAP profile. Impact: An invalid profile can be created. Workaround: You need to follow the instructions in the Cisco DSL Manager NI-2 User Guide to select the correct baud rate.
CSCdt38161	When a user creates a profile in the DMT Interface Profile window, the default value for the field Codeword Size is 0. However, 0 is an invalid value in IOS and results in a profile rolldown. Impact: The user is unable to correctly create a DMT profile. Workaround: Modify the DMT profile by using the down arrow to select a number other than 0. Apply the profile.
CSCdt38323	The status bar in the ATM QoS Profiles Configuration window displays the number of times that the profile is attached to a PVC. However, the tracking goes from 0 to 1 and stops at 1, no matter how many times the profile attaches to a PVC. Impact: You cannot correctly track the number of times a profile is connected to a PVC. Workaround: None.
CSCdt49250	The bit rate value of 1552 for G.SHDSL line cards is not available in CDM or IOS. Impact: You cannot choose this value, although it is valid. Workaround: None.
CSCdt49284	The SDSL Profile window does not include an option to enter the SHDSL margin threshold. Impact: You cannot set the margin threshold by using CDM. Workaround: You must use IOS to set the margin threshold.
CSCdt52141	When you manually deploy a DSLAM, it is deployed under a subnet that is based on class IP addressing. When you deploy a DSLAM using autodiscovery, it is deployed based in the subnet mask in the Cisco EMF Autodiscovery window. If the subnets are different, you can add the DSLAM more than once. Impact: You can erroneously deploy more than one DSLAM having the same IP address under the same site. Workaround: When you deploy a DSLAM through autodiscovery, use class addressing subnets. If you have deployed more than one DSLAM with the same IP address, delete the duplicate DSLAM using these steps: 1. Make sure you decommission the DSLAM if you have commissioned it. 2. From the left side of the Map Viewer window, right-click the name of the duplicate DSLAM that you want to delete. 3. Choose Deployment > Delete Objects from the object menu. 4. Click Finish in the Deployment Wizard Summary window.
CSCdt57886	A message displays that says "Application exiting. Connection has been lost to the CEMF Client platform." Impact: CDM windows close. Workaround: Reopen the applicable CDM window.
CSCdt69394	When you apply a profile that has an incorrect value, no error message or alarm displays. Impact: You can be unaware that a problem with the applied profile has occurred. Workaround: None.
CSCdt80110	CDM needs to support fast path latency for 8xDMT and FlexiDMT interfaces. (This does not pertain to 4xDMT line cards.) Impact: Currently you can use only interleaved latency paths for 8xDMT and Flexi DMT line cards. Workaround: None.
CSCdt81720	It can take an hour to delete a DSLAM that contains a large number of PVC connections. Impact: The time it takes to delete a DSLAM that contains a large number of PVCs can be a problem. Workaround: None.
CSCdt82858	When most of the slots in a DSLAM are filled and you place interface cards in the remaining slots, the system begins a subrack discovery. The subrack discovery process can take over 20 minutes and also causes up to two-thirds of the modules to go into a "Module commissioning failed" state. Some of the module states display as "discoverylostcomms" and some display as "normal," which is an incorrect state for a module that has lost communication with the server. Flexi cards have fewer errored states in these situations. Some of the Flexi cards that are preprovisioned can have a "Module commissioning failed" trap display, but the Flexi cards that are actually present in the chassis are normal. However, the 4xDMT, 8xDMT, and IDSL modules all display a "Module Commissioning Failed" error state. Impact: A subrack discovery occurs whenever you insert any module into the DSLAM and the system takes a long time to complete the subrack discovery process. If you insert a card and the DSLAM discovers it, you probably do not want an entire subrack discovery to occur, only discovery for that particular card. Workaround: Decommission and commission the modules again, but in smaller groups such as 10 to 15.
CSCdt83755	When you deploy and commission a Cisco 6160 DSLAM, it can take over an hour for CDM to complete the commissioning process. Impact: Under heavy data loads, commissioning takes a long time. Workaround: None.
CSCdt83962	If you have to delete the configuration in a DSLAM that has been deployed and commissioned with 128 SPVCs (for example, replace an NI-2 card, or solve some other hardware problem), CDM still assumes there are 128 SPVCs present. However, these 128 SPVCs are no longer present after you delete the configuration. To get CDM back in sync with the DSLAM, you would have to manually delete each module. To save time, you might try to upload an unconfigured DSLAM. CDM would have to delete all of the SPVCs that were previously commissioned. If you open the upload management window to upload the running configuration, it will take 10 minutes for the DSLAM to appear in the right side of the window. If you click Upload, it will take 25 minutes for the upload process to complete. Impact: Any solution you choose can take a long time. Workaround: None.
CSCdt83995	The configuration and status windows for interfaces can take as long as 2 minutes to display. This delay occurs in a configuration that has 100 simulated DSLAMs that are deployed and commissioned. Impact: Users cannot get a timely response to their actions. Workaround: None.
CSCdt84321	Sometimes the user is unable to apply a CAP profile to a flexiCAP module. Impact: You cannot apply a CAP profile. Workaround: If you continue to apply the profile, eventually the CDM applies the profile.
CSCdt84909	If you reload the running configuration on a DSLAM, the following values are not set: •snmp-server host 172.18.101.92 public •snmp-server host 172.18.101.92 v2c After you add these values, decommission the DSLAM, and then commission it again, only the NI-2 card recovers. No line cards recover. Impact: As above. Workaround: Decommission the DSLAM, delete it, and then redeploy it.
CSCdt85904	When you create a profile and then close the Interface Profile window before the action has completed, CDM managers exit and dump core. Impact: Any other status or configuration windows that are open at the time can disappear. The profile is created in the Cisco EMF database and you can view the profile when you reopen the Interface Profile window. Workaround: Do not close the Interface Profile window before CDM has finished creating the profile; wait until the interface returns to the normal state.
CSCdt86867	Sometimes when you apply an ADSL profile to a port object, no change occurs. Impact: CDM does not apply the profile to the port. Workaround: Stop and restart the ATMADSLDMTCon process by entering the following commands: Run /opt/cemf/bin/cemf shell; /opt/cemf/bin/sysmgrClient -k ATMADSLDMTCon; /opt/cemf/bin/sysmgrClient -x ATMADSLDMTCon
CSCdt95086	When you insert a module into a provisioned slot, the alarm that informs you of a provisioned slot being empty does not clear from the Event Browser window. This occurs when a module is in an active state. Impact: The slot is empty alarm continues to display. Workaround: You must manually clear this alarm.
CSCdu04543	When you create PVCs or SPVCs and enter data in the Subscriber Info field in the Deployment Wizard—Object Parameters window, CDM does not always register the Subscriber ID. In these instances, after you have completed upload management, the Subscriber ID does not display in the Subscriber Info field in the ATM Connections Management window. Impact: No subscriber ID displays. Workaround: None.
CSCdu05488	If you create a site name that includes spaces, this causes problems in the CNOM GUI set_line_ids file. Impact: A failure in the set_line_ids function results. Workaround: When you create a site name, avoid using spaces in the name.
CSCdu07055	When you deploy an SPVC in the Deployment Wizard—Templates window, and you click SPVC with non-CEMF endpoint, CDM might not create this SPVC with a non-CEMF endpoint. Impact: A failure occurs when you are making a connection on non-CEMF endpoint SPVCs. Workaround: None.
CSCdu11892	If you open the Add Subtend PVC window (by right-clicking an interface and choosing Cisco DSL Manager > Add Subtend PVC) from any hierarchy view other than the ComponentManaged or the SubtendPVC view, the PVCs that you create do not display in this window. Impact: CDM creates the PVC, but does not display it. Workaround: Open the Add Subtend PVC window from either the ComponentManaged or the Subtend PVC view.
CSCdu12342	When you change the configuration of a subtend DSLAM, the node that was used previously for the subtend configuration keeps the old subtend IP address with the subtend port. This incorrect address identification happens if you do not create a new IP address for the subtend port. Impact: When you use autodiscovery, CDM discovers the incorrect subtend topology. Workaround: None.
CSCdu12658	The software can map entity traps to an incorrect object in CDM. This error occurs if the entPhysicalIndex of an object changes during subrack discovery; the device sends out entity traps during subrack discovery. Impact: Traps are mapped to an incorrect object in CDM. Workaround: Open the Event Browser window to read trap descriptions.
CSCdu17230	The Cisco EMF coordinator process can crash when you stop Cisco EMF while CNOM is running in parallel. Impact: The process crashes. Workaround: Stop Cisco EMF again, and then restart Cisco EMF.
CSCdu20128	If you use Reflection X to run the CDM client, the ADSL Interface window can unexpectedly close and crash. This problem occurs when you have the Window Mode set to X terminal desktop and the Default local window manager set to Reflection Window Manager. Impact: ADSL windows disappear. Workaround: Use the Reflection X default settings when using this application to run the CDM client. To check the window settings, choose Windows Manager from the Settings menu in the Reflection X menu bar. Doing this opens the Windows Manager Settings dialog box. Set the window settings fields as follows if they are not already selected: •In the Window mode field, click Microsoft Windows desktop. •In the Default local window manager field, click Microsoft Windows.
CSCdu51687	All of the PEM⁶ traps go to the chassis, which is okay. However, if a PEM is not detected or missing and you look in the Event Browser window for the error message, it indicates that the chassis is not detected or missing instead of indicating that the PEM is not detected or missing. Impact: You think that the chassis is not detected or missing when it is actually the PEM that is missing. Workaround: Look in the Map Viewer window to see that the chassis is present but the PEM is missing.
CSCdu54294	The chassisOiD requirement when you deploy a profile object is not necessary. CDM can get this information from the containmentSpec inside the objectDef of the profile. Impact: Front-end applications such as CNOM need to provide chassisOid as an attribute in objectDef. Workaround: Enhancement.
CSCdu63324	The Frame Relay connection synchronization does not work. Impact: As above. Workaround: None. This does not impact the user with this release.
CSCdu68515	The choices for DMT training mode do not include g992.1, g992.2, and T1.413, as supported by IOS, but this field displays splitterless in the XDSL Interface Manager window. Impact: You cannot select g992.1, g992.2, or T1.413 training mode for various DMT devices. Workaround: Use IOS to set the correct training mode.
CSCdu87042	The data migration restore process is unable to properly restore the QoS profile names when there are duplicate profiles in CDM. Impact: The profile names are not restored properly. Workaround: None.
CSCdv11582	A subtend PVC is not always able to use the ATM autoallocation feature (to have CDM autoallocate the source or destination VCIs and VPIs). Impact: If a subtend PVC uses autoallocation, it might fail. Workaround: Create a subtend PVC without using autoallocation. In the Add Subtend PVC window Source and Destination areas, use the down arrow to select No in the Auto Allocate fields.
CSCdv11693	If you attempt to save a profile on a chassis that is decommissioned, a message displays that the profile has been saved. However, the profile is not really saved; this can happen if the XDSL Interface Manager window is already open when you decommission the chassis. Impact: The profile that you try to save on a decommissioned chassis is not saved on the device, and you are not informed about the failure to save the profile. Workaround: After you have decommissioned the chassis, close and then reopen the XDSL Interface Manager window.
CSCdv12178	The length of the name for an xDSL profile is limited to 32 characters in IOS, but can have 256 bits after SNMP encoding. Impact: Some xDSL profiles that you can upload from IOS do not display any data in the XDSL Interface Manager window. Workaround: When you create a new profile, avoid using a name whose length might be greater than 256 bits after SNMP encoding.
CSCdv13904	When the Chassis Polling/Connection Policy window is open, you cannot access the Cisco EMF online help. Impact: You cannot open Cisco EMF online help in a browser when you press the ? button. Workaround: See the Cisco Element Management Framework User Guide or the Cisco DSL Manager NI-2 User Guide for the topic you need, or use the tooltips.
CSCdv16358	You cannot enable a link up/link down trap when configuring an xDSL profile. Impact: In addition to not being able to enable a link up/link down trap when you configure an xDSL profile, you also cannot determine whether the link up/link down trap is enabled in the XDSL Interface Manager window. Workaround: Enable the link up/link down trap from the IOS CLI by using the snmp trap link-status command.
CSCdv20057	You cannot rename a chassis once it has been deployed. Impact: It is difficult to change a chassis name once it appears in CDM. Workaround: To change the name of chassis that you have already deployed, you must first delete the chassis and then redeploy it using the new name.
CSCdv29290	Alarm synchronization does not synchronize link up/link down traps. Impact: Missed link up/link down traps are not synchronized. Workaround: None.
CSCdv37825	Attributes are listed in the Performance Management window whose performance cannot be monitored. Impact: You might try to monitor these attributes, but no data displays to the Table and Graph tabs. Workaround: Select only those attributes whose performance might be actively monitored.
CSCdv38327	A misleading error message displays when you provision a connection through CNOM⁷ if passwords are not set. Impact: The error message "CDM_505 unable to set up PVCs in the subtend path" does not imply that the password is not properly set up. Workaround: Make sure passwords are set before you provision connections using CNOM. Note Resolution of this DDTS is postponed.
CSCdv45469	The hourglass disappears before CDM retrieves chassis summary information. Impact: You have to wait for the Chassis Summary window to open even after the hourglass disappears. Workaround: None.
CSCdw45645	When profiles are being synchronized between CDM and the DSLAM, the following error occurs in the XDSLCtrl.log: "ERROR: Converting attribute section to real section" Impact: This error does not affect synchronization. Workaround: Disregard this error message when it appears in the XDSLCtrl.log.
CSCdw54913	When you create or modify an xDSL profile in the XDSL Interface Manager window, you might enter invalid data in fields that do not include a down arrow that you click to display valid values. Impact: The XDSL controller does not validate all of the xDSL profile parameters and some data returns an SNMP bad value error; for others, SNMP accepts the invalid values and sets them to device. Workaround: Enter only valid values for profiles when you configure or modify an xDSL profile.
CSCdw58920	When you create a subtend PVC, individual PVCs are created on the nodes with matching VPI/VCI pairs. If a situation exists in which, for example, three nodes are subtended, and the PVC creation succeeded on the first two, but fails on the third node, the system should delete the PVCs on the first two nodes; they are not viable. However, the subtend PVCs that you created on the first two nodes still display in the Map Viewer window. Impact: The PVC in each of the subtended nodes remains in CDM; the PVCs appear to exist, because you can still see them in the Map Viewer window, but they do not. Workaround: Use one of the following workaround steps: •Take extra precaution before you create a subtend PVC. Make sure the user name and password are set for the chassis. Select only those VPIs or VCIs that are available in the subtended chassis for the subtend PVC. •Set the device to be the master (DeviceisMaster) in the connection synchronization policy so that when the next synchronization time occurs, the stranded PVCs are removed from the CDM database. (Choose DeviceisMaster in the Connection Policy area of the Chassis Polling/Connection Policy window. Refer to Chapter 4 in the Cisco Digital Subscriber Line Manager NI-1 User Guide for more information.)
CSCdw60940	The restore operation in data migration does not check to see whether enough disk space exists in the system for the log files. Impact: Not all the data is restored if not enough disk space exists. Workaround: Make sure you have enough disk space for the cemf log files before you run the restore operation. For a 100-DSLAM configuration, 100 MB should be enough space.
CSCdw62251	The XDSL controller contains some synchronous calls. Impact: XDSL-related operations are slow. Workaround: You must wait a longer time for xDSL operations.
CSCdw65901	CDM does not update the subtend cache when you delete multiple subtend chassis. Impact: Subtend discovery will fail the next time the chassis is deployed. Workaround: Delete each of the subtend chassis one at a time. Alternatively, you can kill the subtend controller, SubtendCon; if you do that, the cache is rebuilt.
CSCdw73531	Some IMA alarms do not display in the Event Browser window. Impact: You are not notified about some IMA alarms, critical or otherwise. Workaround: You must use the IOS command show facility-alarm status to see all the alarms from the device.
CSCdw78711	When you create a subtend PVC, CDM might not automatically refresh the Subtend PVC view. Impact: You might think that the creation of the subtend PVC has failed. Workaround: Click the Subtend PVC icon on the Map Viewer window to see the children (PVCs), or close and re-open the Map Viewer window.
CSCdw82805	If you click Cisco DSL Manager > Technology Commands > reset card from a module, the card does not get reset. Cisco IOS does not support this command. Impact: You cannot reset the card using this command. Workaround: None.
CSCdw85890	In the SNMP tab of the Interface Summary window, the traffic light for the No Peer Present field does not correctly display for an SDSL interface. Rather than displaying a red light for no peer present, or a green light if a peer is present, this field displays a circle with a slash across it. Impact: You cannot see the correct value in the No Peer Present field for the SDSL interface. Workaround: The SNMP tab is not applicable to an SDSL interface.
CSCdw87217	The cdmController experiences memory leaks in two places, even when not in use. Impact: The cdmController increases memory use over time. Workaround: None.
CSCdx02969	When you commission a large number of DSLAMs (for example, 135) and allow the commissioning process to run overnight, some interfaces might be stuck in commissioning state the next day. Impact: You cannot manage ports that are in commissioning state. Workaround: Decommission and recommission the chassis whose ports are are in commissioning state.
CSCdx02976	When you commission a large number of DSLAMs (for example, 135) and allow the commissioning process to run overnight, some interfaces might be stuck in a discoverylostcomms state the next day. Impact: You cannot manage ports that are in a discoverylostcomms state. Workaround: Decommission and recommission the chassis whose ports are are in a lostcomm state.
CSCdx05896	When you perform an ATM connection upload on multiple DSLAMs, a dialog box opens to inform you of the status of the synchronization process. If you select more than one DSLAM for the ATM connection upload process, CDM uploads only one DSLAM at a time. The dialog box provides status about only the one DSLAM that is currently being uploaded; the status does not include the summary of the entire chassis list. Impact: It appears that only one DSLAM has been uploaded when you have actually selected multiple DSLAMs for ATM connection upload. Workaround: None.
CSCdx05905	When you attempt to disconnect SPVCs that were created through the CORBA interface, the disconnect is successful; however, writing to the startup configuration fails. Impact: The write memory operation fails; the disconnected PVC configuration is not saved in the startup configuration. Workaround: Use CDM or IOS rather than the CORBA interface to create SPVCs. Or, manually issue a write memory request after the SPVC is disconnected.
CSCin04350	If the active NI card fails and you switch to the redundant NI card, the switchover takes place. However, connections do not display under the new active NI card on the Map Viewer window. Impact: After the NI card switchover occurs, connections that initially displayed below the NI interface icon on the Map Viewer window are no longer visible. You can no longer manage these connections from CDM. Workaround: Delete and redeploy the chassis.
CSCuk23194	You cannot simultaneously commission a chassis map in more than one hierarchy view, for example, in both the Physical hierarchy view and the Component Managed view. Impact: The bitmap of the DSLAM chassis appears in only one Cisco EMF view. Workaround: None.
CSCuk32473	During the subrack discovery process, if the DSLAM loses communication with the CDM server (discoverylostcomms state), the DSLAM might get stuck in the discovery state. Impact: Chassis cannot get past the discovery state. Workaround: None.
