Release Notes for Cisco 6400 Service Connection Manager, Release 2.1(1)


The Cisco 6400 Service Connection Manager (SCM) is a Cisco Element Manager Framework (CEMF) based element and service management solution for the Cisco 6400 Universal Access Concentrator. This release note contains compatibility and known problem information which may be relevant for installers and end users of the Cisco 6400 SCM solution. Also noted are a number of Cisco 6400 UAC hardware issues that may have an impact on the normally routine operation of the Cisco 6400 SCM software.

SCM Release 2.1(1) provides a new monitoring tool feature along with scalability enhancements and bug fixes. Like SCM Release 2.0.1, this release of SCM also runs on CEMF Release 3.0.4.

Audience

SCM Release 2.1(1) applies to both new and existing installations of SCM. Customers who are installing SCM for the first time must install SCM Release 2.1(1).

New Software Features in SCM Release 2.1(1)

In addition to the features supported in SCM Release 2.0 and SCM Release 2.0.1, SCM Release 2.1(1) supports the following features:

Software Features in SCM Release 2.1(1)

SCM Release 2.1(1) runs on Cisco EMF Release 3.0.4, which implements several changes that are visible in the Cisco SCM software:

Cisco 6400 Services Supported in Cisco 6400 SCM, Release 2.1(1)

The following Cisco 6400 aggregation services are supported in this release:

System Requirements

Cisco CEMF Version 3.0 can manage large-scale deployments. Customers planning to upgrade to this release should use the recommended deployment hardware specification for the CEMF Version 3.0 server:

Software Compatibility

This software release was tested on Release 2.6 of the Solaris operating environment, for Sun SPARC workstations, and for Year 2000 Compliance. This software release runs on the Cisco EMF Release 3.0.4 platform with CEMF Release 3.0.4 patch 9.

Additionally, Cisco 6400 SCM Release 2.1(1) is compatible with the following versions of Cisco IOS:

Determining the Software Version

To determine installed Cisco EMF packages and version numbers, use the CEMF command:

<CEMFROOT>/bin/cemf install -show

Note   <CEMFROOT> is the installation directory for CEMF and the Cisco 6400 SCM software. The default location is the /opt/cemf directory.

Alternatively, to determine installed Cisco EMF packages, use the Solaris command sequence:

pkginfo | grep -v SUNW

To determine the versions of installed Cisco EMF packages, use the Solaris command:

pkginfo -l <package name>

Upgrading to SCM Release 2.1(1)

To upgrade from an SCM 2.0(1) version to SCM Release 2.1(1), you must:


Step 1   Perform a database backup. Use the migration tool to back up and extract the existing database. Refer to the guide Upgrading Databases to Cisco 6400 Service Connection Manager for details on how to use this migration tool.

Step 2   Verify the patch level and install CEMF Release 3.0.4 patch 9, if it is not installed already.

To determine installed Cisco EMF packages and version numbers, use the CEMF command:

<CEMFROOT>/bin/cemf install -show

Step 3   Enter the command:

cemf load -upgrade CEMFSCMm

# (or the client package (CEMFSCMc), as appropriate)

Step 4   Enter the command:

cemf load <new package directory> /packages CEMFSCMm

# (or the client package (CEMFSCMc), as appropriate)


Note   If the upgrade is not successful, perform a database restore from your backup.



Upgrading to SCM Release 2.0(1) from SCM Release 1.2 or SCM Release 1.3

SCM Release 2.0(1) includes a migration tool for managing an existing SCM database in an SCM 1.2 or SCM 1.3 installation so that it is accessible after upgrading to SCM 2.0(1). To upgrade from an SCM 1.x version to SCM Release 2.0(1), you must:

For details on how to use this migration tool, refer to the guide Upgrading Databases to Cisco 6400 Service Connection Manager.

If you are upgrading from SCM Release 2.0, you must uninstall SCM Release 2.0, install CEMF patch 5 (or later), and then install SCM Release 2.0(1).

Installation Notes

Read these important installation notes before you begin

CEMF Release 3.0.4 with patch 9 is required for SCM Release 2.1(1).


Note    CEMF Version 3 supports online element manager installation, so the Cisco 6400 SCM must be installed onto a running CEMF server.

You must determine if there are any packages named AVm or AVc in the Solaris packages directory. To do this, examine this directory by entering:

ls -lrt /var/sadm/pkg |grep AV

Then remove any AVm package or AVc package by entering the following commands:

cd /var/sadm/pkg/AVm [AVc]

rm preremove

cd /var/sadm/pkg

pkgrm AVm [AVc]

cd/var/adm

rm -rf Atlantech

The following conditions pertain to installation and startup times, especially if you are using hardware specifications less than the minimum recommended in this document.

mv /etc/rc2.d/S99cemf /etc/rc2.d/Unused-S99cemf

Version Support

For this SCM release, the CEMF Version 3.0.4 and the CEMF 3.0.4 patch 9 components must be installed.

Uninstalling SCM

To uninstall the Cisco 6400 SCM, use the option cemfinstall -r as described in the Cisco 6400 Service Connection Manager Installation Guide.


Note   If you remove an element manager, this renders any database objects related to that element manager unusable. Use the upgrade procedure in the Upgrading Databases to Cisco 6400 Connection Manager Release 2.0.1.

Important Notes: Adding Additional Swap Space

CEMF Version 3.0.x requires 2 gigabits of swap space. In general, if your machine requires additional swap space, you should repartition one of the disks to allocate a new swap partition. Use the Solaris command format (1M) and in particular the partition option of this command to partition appropriate swap space.


Note   If you must repartition an existing disk to increase swap space, consult a Solaris system administrator. Repartitioning a disk means that you lose all data on that disk.

A simple, but less efficient (in performance terms) method of increasing swap space is to create a file as follows and add the file to your available swap. The following example shows how to add 1 gigabit swap to your Sun workstation (assuming sufficient available free disk space).

mkfile 1000m /opt/MY_EXTRA_SWAP_FILE
swap -a /opt/MY_EXTRA_SWAP_FILE

To ensure that this file is added to your swap after a system reboot, remember to add it to your machine's /etc./vfstab file. If in doubt, consult a Solaris system administrator.


Note   This is not a particularly efficient swap file system and results in slower application performance.

Closed Caveats

Caveats Closed Since Last Release

This section list caveats that have been fixed since the last Cisco 6400 SCM software release.

Cisco EMF Version 3.0.4 Open Caveats

For a full list of known problems in Cisco EMF Version 3.0.4, consult the appropriate CEMF release note.

Table 1 lists CEMF issues that affect the operation of Cisco 6400 SCM Release 2.1(1).

Table 1   Cisco EMF Version 3.0.4 Caveats

Caveats Description

CSCdr19601

It is currently possible to deploy subscribers on objects other than ATM ports. This is not a valid deployment option and you must avoid using it.

Workaround: None.

CSCdr19677

In the generic deployment wizard, under the select relationship dialog, if you select the PHYSICAL object more than two times, an error message appears indicating that no object was selected.

Workaround: None.

CSCdr19684

Access security by management region (data partitioning) does not function correctly if the domain is set up at a CEMF site level.

Workaround: None.

CSCat15804

If you attempt to perform a Cisco IOS image download to a device in the errored state, this results in an Unable to Login error message if the device is not operational.

Workaround: None. Do not perform a Cisco IOS image download to an errored device.

CSCat20118

Excessive logging messages are output to the c6400Controller.log file, which can make it difficult to find error messages in the log file.

Workaround: None.

CSCat20077

If an NLC is predeployed into a slot that is occupied by another type of NLC, the object may go into the normal state when commissioned instead of a mismatched state.

Workaround: Delete the incorrectly deployed NLC and deploy the correct NLC.

SCM Release 2.1(1) Open Caveats

Table 2 lists known problems in Release 2.1(1) of the Cisco 6400 SCM. Unless otherwise noted, there is no workaround.

Table 2   Cisco SCM Release 2.1(1) Caveats

Caveats Description

CSCds69176

After you upgrade from SCM Release 2.0.1 to SCM Release 2.1(1) and launch the PVC Usage function from a chassis object, the PVC Usage window shows a list of all deployed chassis in the chassis list box. A larger list of chassis appears rather than the list that normally appears when the PVC Usage window is launched from that point.

Temporary Workaround:

Launch the PVC Usage option from a Shelf or a Site instead of a chassis.

Workaround:

To resolve the problem:

1. Identify the objectServer process ID (PID). Type:

ps -ef | grep objectServer

2. Abort this process (you must be root). Type:

kill -9 <PID of objectServer>

The sysmgr process will notice that objectServer has been disabled, and restart it.

All PVC Usage chassis list boxes now populate correctly.

CSCdr21084

The system permits you to edit the NLC ATM Port window Configuration tab and More Configuration tab fields when they should not be editable. If you attempt to edit those fields, an error is generated in the Action Report.

Workaround: None.

CSCdr34017

You cannot use the Chassis Configuration window to enable and disable power supplies. An error dialog box or Action Report appear.

Workaround: Use the CLI.

CSCds24801

The More button on both the SysLog Messages and Command Log windows appear to serve no function.

Workaround: Ignore the button.

CSCds25753

The tooltip text for the Connection Details list box on the Subscriber Configuration window always reads L2TP Service Connections, even though this field may contain any type of service connection.

Workaround: Ignore the tooltip text.

CSCds25790

TAB indexing in the Deployment Wizard does not include the Forward, Cancel, and Finish buttons on the bottom of each window.

Workaround: Use the mouse to click these buttons instead of using the Tab key.

CSCds26818

When you decommission an interface using the Interface Configuration window, all of the values in the Configurable Parameters window go blank.

Workaround: Select another interface, then reselect the interface that was just commissioned. The values reappear.

CSCds26825

When you decommission or commission a Port object (using the Interface Configuration window), the Action Report displays a variable name and not the appropriate message.

Workaround: None.

CSCds28088

The Performance menu option is not available from any NLC objects, so the user cannot navigate to the Module Performance window from an NLC object. You must add the Performance option to the Module > Manage menu for NLC objects.

Workaround: You can launch the Module Performance window from an NRP or NSP object and then select the NLC from the list box of modules.

CSCds33160

Not all windows contain the Commission Status field at the bottom of the window.

Workaround: If the interface icon in the Viewer has cross-hatching, the icon is decommissioned. If there is an error with the object, you use the icon bomb or Event Browser to determine this state.

CSCds38146

When the user starts Commissioning or Decommissioning a service, the wait cursor does not appear and there is no indication in the status bar.

Workaround: Click the Commission or Decommission button only one time and wait until an Action Report appears.

CSCds39272

When the user tries to save an invalid value in one of the Temperature Threshold Configuration frame fields (on the Cisco 6400 Chassis Management window), an error message appears.

Workaround: None.

CSCds39899

When data is being loaded, the cursor has an arrow shape instead of a clock shape, which can be confusing.

Workaround: None.

CSCds40231

The Cisco 6400 UAC > Configure drop-down menu that is accessed from the Connection Templateobject is inconsistent with the rest of the drop-down menus. The drop-down menu option should not be Configure. The Connection Template should appear first.

Workaround: None.

CSCds40795

If you configure the NRP to use a fast Ethernet port instead of an Ethernet port and then issue the show nrp-ip-address slot x command, the NSP displays a blank response from the NRP.

Workaround: None.

CSCds42811

Each time you update the Capacity Monitoring tool window using the Update button, an extra zero (0) is added to the VPI column in the VPI Statistics table of the Interface tab.

Workaround: None.

CSCds64137

In the Access Manager window, the description of available feature lists does not contain the horizontal scrollbar. The description may be longer than the limits of the field box.

Workaround: None.

CSCat16169

If a subscriber is connected to a service without a local profile configured, the ssg vc-service statement is bound to the zero (0) service.

Workaround: Never set up a configuration to have pppoa_statically connected to an IP-Uplink service without a local service profile configured.

CSCat16713

On the Connect to Single Domain tab of the Connect window, if an IP-Uplink service instance (with no LSP configured) is selected, the Connect button should be grayed out, but it is not.

Workaround: None.

CSCat18434

Negative values may display for In Octets, Out Octets, Out Unicast Packets, as well as in the NLC ATM performance window.

Workaround: None.

CSCat19449

The critical alarm that occurs when you enter an improper IP address, does not clear after the chassis returns to a normal state.

Workaround: None.

CSCat19975

In the Line Card ATM Port Management window, the following attribute values in the Fault tab window (SONET Frame Errors area) are reversed. The value for the Path FEBE Errors field reflects the value of the Line FEBE Errors field.

Workaround: None.

CSCdr34536

The Restore option (of a previously running configuration) for the NSP object functions correctly, but falsely prints an error message stating that a problem has occurred. The error message is incorrect; the restore worked properly. For the NRP, this option functions correctly. No erroneous error message appears.

Workaround: None.

CSCat19415 CSCat19519

You can delete a decommissioned NRP or chassis even though there is a commissioned service associated with it.

Workaround: Examine the services associated with an NRP object or a chassis object and its cards before you delete it.

CSCds27777

If you select Yes for the CPE supports ARP option in the RFC 1483 Routing Service Configuration window, the PVC IP Address fields are grayed out.

Workaround: When you select the CPE supports ARP option, do not use the PVC IP Address fields.

CSCds57219

The menu option for Cisco 6400 Profile configuration may be confusing.

Workaround: Use the Service Uplink service profile menu option to configure RFC 1483 routing services.

CSCds32155

On only one occasion, leftover element manager packages that were not properly removed caused problems, such as the commission and decommission buttons not operating correctly or the autodiscovery feature not functioning properly.

Workaround: Determine if there are any packages named AVm or AVc in the Solaris packages directory. To examine this directory, type:

ls -lrt /var/sadm/pkg |grep AV

Then remove any AVm package or AVc package by entering the following commands:

cd /var/sadm/pkg/AVm [AVc]

rm preremove

cd /var/sadm/pkg

pkgrm AVm [AVc]

cd/var/adm

rm -rf Atlantech

CSCds45025

The Configuration Restore functionality does not work.

Workaround: If it is necessary to restore the backed-up configuration file, the user can do this using CLI commands as follows:

1. Copy the saved config file to the startup-config file on the selected device.

2. Restart the device.

CSCds27745

Users are required to enter CLI Password information in too many places.

Workaround: Enter information in all appropriate fields.

CSCds27843

The Deploy and Commission process is confusing. It is easy to make mistakes.

Workaround: Study the documentation in detail.

CSCds33065

Cisco IOS CLI Security usernames and passwords are not always visible or inherited.

Workaround: When you select line card or other module objects, do not make entries in these fields. These entries are not used and may cause unexpected results if the entries are incorrect.

CSCds40054
CSCds40160
CSCds40172
CSCds40182

The Deployment process does not check the presence of invalid Chassis IP addresses.

Workaround: The user must be careful not to enter an invalid Chassis IP address.

CSCds43018

You can deploy NSP and NRP objects anywhere without any errors.

Workaround: Be careful when you deploy NSPs and NRPs. Make certain that they are being deployed under the correct object.

CSCds45085

You are allowed to delete Network tree network containment icons.

Workaround: None.

CSCds46048

An Object in reset state cannot be deleted from the window.

Workaround: Rename the current NRP object and change its IP address to a different, unused IP address such as 0.0.0.0. Then you can deploy a new NRP object to replace the old one. If an NSP fails in this manner, you must change the IP address or names of all other objects under the NSP, so that when you deploy the new objects, you do not create duplicate IP or name failures.

CSCds52514

The SSG Config button does not save configuration changes.

Workaround: Press Save before you click the Configure button.

CSCds53247

Using the mouse, you can paste illegal values into dialog box fields even though a keyboard entry cannot.

Workaround: Always use the keyboard for entering data in dialog box fields.

CSCdr20489

The Maximum Table Entries field in Command Log window does not get saved.

Workaround: None. You cannot increase or decrease the number of table entries displayed.

CSCds18236

The Tech Spec Tools menu does not appear. This is inconsistent with documentation and the CDM element manager.

Workaround: Initiate a Telnet session by using the menu option Cisco 6400 UAC > Tools > Initiate Telnet Session NSP and NRP icons.

CSCds23071

Object status, listed in the status bar at the bottom of several dialog boxes, does not display a new change in status.

Workaround: Close the dialog box and reopen it.

CSCds24842

When you deploy objects with duplicate IPs, the SCM does not report any failure.

Workaround: None.

CSCds25129

Deployment failure causes the Action Report to appear with a nondescriptive Deployment Failed error message.

Workaround: Check to see if an object already exists in that slot and try deployment again in another slot.

CSCds26168

After the successful backup of an object's configuration, the Time Stamp of the last Backup field does not update.

Workaround: None.

CSCds27071

All Help windows are out of date (graphics and text).

Workaround: None.

CSCds29313

The Web Console does not launch from SCM.

Workaround: Manually launch the web browser and enter the IP address for the device to be managed in the Browser Location field.

CSCds32056

You cannot change SNMP CommStrgs for NSP/NRP from their icons.

Workaround: From the Site or Shelf icon in the Viewer, use the right mouse button to open the SNMP Management window. Use the selection panel in the window to select the NRP or NSP to be modified.

CSCds34989

If the menu for applying and deleting service profiles gets too large for the window, SCM automatically divides the window into multiple, cascading menus. This feature works correctly, but the list item that you click to get to the next menu of profiles is incorrect.

It displays &menuMore and not the correct text, which is More or More profiles.

Workaround: Use the menu option to properly expand the menu selections.

CSCds35202

The final remaining Service Profile does not delete properly.

Workaround: After you delete the only profile in a profile list, close and relaunch the Service Configuration window.

CSCds37258

The Navigation menu appears in some windows erroneously.

Workaround: The Navigation menu is not functional at this time, and should not be used when displayed.

CSCds40015

The System Name in NSP and NRP Management windows does not always match the IOS hostname.

Workaround: Realize that the SNMP sysName object (System Name in the SCM dialog boxes) is the concatenation of the Cisco IOS CLI hostname and ip domain-name. The first dot (period) in sysName is the divider between hostname and ip domain-name. The parameter ip domain-name does not clear its previous settings unless a new ip domain-name is used either in Cisco IOS CLI or by providing a dot-delimited name with domain in the System Name field in the SCM windows.

CSCds40178

The Connection template can be deleted with active connections using it.

Workaround: Remove all of the active connections using the template before you remove a template.

CSCds41167

The Connection Template > View Connection menu does not work.

Workaround: Access the Service/Subscriber Connection window for each ATM service connection and check which connection template is used with each connection.

CSCds42139

Commission/decommission NSP does not have any effect on objects under it in the device tree.

Workaround: Decommission the Chassis or Shelf icon to decommission all objects in the device tree.

CSCds23071

All Service windows always appear as Decommissioned even when they are in a normal state or commissioned.

Workaround: To determine if the chassis is truly Commissioned or Decommissioned, view the icon status in the Viewer.

CSCds44535

You cannot turning off polling.

Workaround: Turn off Performance Logging, then perform a cemf stop and cemf start on the manager workstation.

CSCds44538

SCM does not map SNMPv1 traps, and CEMF cannot forward SNMPv2c traps.

Workaround: None.

CSCds45972

The CapMon VCC space utilization alarm does not clear automatically when the alarm is cleared.

Workaround: Enter the Event Browser and clear the alarm manually.

CSCds52901

You cannot remove SCM using the cemfinstall -r command.

Workaround: The cemfinstall routine does not remove components which may be used by other Element Managers. When you upgrade from one version of SCM to another, install the new version on top of the existing version of SCM.

When an element manager needs to be removed entirely, use the CEMF command string /opt/cemf/bin/cemf install -r. The command cemf load -remove can also be used to remove named packages on an individual basis.

CSCds53253

No error checking occurs before you run the SSG Configuration script.

Workaround: None.

CSCds55016

A Major Alarm does not clear after an IP address is given to NRP.

Workaround: Enter the Event Browser and clear the alarm manually.

CSCds55491

No alarms are raised in the Event Browser when the temperature is out of range.

Workaround: View the temperature alarm in the Cisco 6400 Chassis Management window.

SCM Release 2.0(1) Open Caveats

Table 3 lists the known problems in Release 2.0(1) of the Cisco 6400 SCM. Unless otherwise noted, there is no workaround.

Table 3   Open Caveats for SCM 2.0(1)

Caveats Description

CSCds20141

Occasionally, object lists in the IOS Download window are populated differently, depending on the Cisco EMF View from which the window is launched. In particular, if you download to a chassis this is equivalent to downloading to the Cisco 6400 NSP. Also, it is possible that duplicates will appear in this list (that is, the chassis and NSP object both appear).

Workaround: Manually check the objects to which you choose to download (especially if you use multiselect).

CSCds20203

If you preprovision a half-height card into a slot in which the other subslot is populated with a live card, this can cause Cisco 6400 SCM to indicate that the preprovisioned card is actually present. The Cisco 6400 SCM incorrectly allows you to Commission this card.

Workaround: None.

CSCds20210

If an NLC is removed from the Cisco 6400 chassis, the Cisco 6400 SCM correctly indicates that this card was removed. However, it is possible that ports on the card are incorrectly marked as being in the normal state.

Workaround: None.

CSCat18377

There may be a mismatch between the number of PVCs on a port as reported by SCM and the Cisco IOS show atm pvc command. The figure reported by SCM is accurate, but includes dynamically created PVCs used for signaling, which are not reported by the show atm pvc command.

Workaround: None.

CSCat19660

If the NRP and NLC objects are deleted from a chassis in SCM, and then subchassis discovery is initiated, the cards are rediscovered correctly. However, these objects may not show all of the alarm conditions present in the alarm table on the Cisco 6400.

Workaround: None.

CSCat19636

It is possible to commission an NRP object that has the same IP address as an existing commissioned NRP object.

Workaround: Decommission the duplicate card and delete it.

CSCat19966

If an NRP card is removed from a Cisco 6400 chassis and inserted into another Cisco 6400 chassis, the SCM should notice this change. However, if the CEMF server fails to receive the chassis change trap from the Cisco 6400, the SCM may always notice. This can occur due to network problems, or if the Cisco 6400 is not correctly configured to send traps to the CEMF server.

Workaround: Manually delete the NRP object from the original chassis, and redeploy it into the new chassis in SCM.

CSCat19951

In the NRP Capacity Statistics window, it is unclear that the Over-Subscription Factor attribute is a percentage value (for example, a value of 15 means that the NRP is 15% oversubscribed, not 15 times oversubscribed).

Workaround: The attribute tooltip provides a clear explanation.

CSCat19519

A decommissioned chassis can be deleted, even though there may be active services and connections on that chassis.

Workaround: None.

CSCat19415

An NRP object can be deleted, even though there may be active services and connections using that NRP.

Workaround: None.

CSCat19914

A subscriber can be connected to the same service more than one time, even though it is usually inappropriate to do so.

Workaround: Disconnect duplicate subscriber connections using the Subscriber Disconnection window.

CSCat19644

Service commission and subscriber connection actions can be launched, irrespective of the state of the port or card.

Workaround: None. If the operation cannot be completed because a port or card is unavailable, the action will fail and revert back to a consistent state.

CSCat20061

In some rare circumstances, the Subscriber Connection window may "hang," displaying the busy watch cursor.

Workaround: Close the window and reopen it.

CSCat19789

The SSG Configuration window can be edited after the Configure action has taken place. When you perform the Deconfigure action, the system tries to remove the edited configuration, which may not match the original configuration on the device.

Workaround: Avoid making changes to the SSG Configuration window after the Configure action has taken place.

CSCat19904

It is possible to delete a commissioned service, or a connected subscriber and connection objects, without removing the corresponding configuration from the Cisco 6400 device.

Workaround: Avoid deleting SCM objects unless you are certain that it is safe to do so. If these objects are deleted, you should manually remove the corresponding configuration from the device using appropriate Cisco IOS commands.

CSCat20193

If you click a tooltip with an Object List, this may cause the GUI manager process to stop responding. This results in the window (and possibly other open windows) closing. Any unsaved changes on these windows are lost.

Workaround: Reopen the window from the Map Viewer application.

CSCat19697

The Connect buttons on the Service/Subscriber Connection window can become disabled or enabled incorrectly.

Workaround: Try selecting a different tab in the window and then returning to the original tab to enable the Connect button. If this does not work, close and reopen the window.

CSCat18935

If two windows are opened in quick succession, their contents can become mixed up, with the contents of both windows displayed in one window.

Workaround: Close the windows and then reopen them.

CSCat19704

The Cisco 6400 UAC menu options are not available if you right-click an RBE connection object.

Workaround: Launch the required window from a parent object or the chassis.

CSCat20005

IP address fields may accept invalid IP address values (for example, 0.0.0.0).

Workaround: Enter a valid IP address.

CSCat19609

It is not possible to deploy a service object by launching the Deployment Wizard using the Cisco 6400 UAC > Service > Deploy menu from another Service object. The wizard requires that you select a containment relationship in the C6400SSManager view, which is hidden.

Workaround: Use the Cisco 6400 UAC > Service > Deploy menu option from the chassis to deploy a service object.

CSCat19318

When an ATM service is commissioned, the Uplink VPI and VCI values for an ATM service are not verified. An invalid value can be entered, which subsequently causes connection to the service to fail.

Workaround: If connection to an ATM service fails, check that the Uplink VPI and VCI values are valid on the ATM Service Configuration window.

CSCat19634

Nonnumeric characters are accepted as valid input in some fields that require numerical values.

Workaround: Avoid using invalid characters in these fields.

CSCat19554

If the Disconnect action is performed on the Service/Subscriber Disconnection window, the following incorrect error message appears: Default Action - Failed: Check Controller log file for more details. Possible error in state machine file.

Workaround: Before you select the Disconnect button, select a Connection object.

CSCat19470

The Connection Template Configuration window and Service/Subscriber Connection windows do not display connection template objects that were created since the window was opened.

Workaround: To display the new connection templates, close and reopen the window.

CSCat19871

The PPP Authentication type mschap does not work correctly on the L2TP and PPPoA-SD configuration windows. The service commission action fails.

Workaround: To use this authentication type, open the Object Configuration window for the L2TP or PPPoA-SD service (right-click the Service object, and select Tools > Open Object Configuration). From the Object Types selector, select VirtualTemplate, then enter ms-chap as the value for the attribute C6400SSControl-MIB.vtAuthenticationType. Save this change, and close the Object Configuration window. The service can now be commissioned.

CSCat19791

In the SSG Configuration window, if the Deconfigure button on the PPPoE Configuration tab is selected, and PPPoE was not configured (or was deconfigured already). An incorrect error message appears (PPPoA is already Deconfigured).

Workaround: None.

CSCat19295

The Connection Template Configuration window does not validate QoS values. Incorrect values are rejected if the connection template is used to connect a subscriber.

Workaround: If an error occurs when you connect a subscriber, check that the connection template contains valid values.

CSCat19399

The Current Connections object list on the ATM Service Configuration window may remain empty, even though there is a connection to this service.

Workaround: Open the Service/Subscriber Disconnection window from the ATM Service object. This shows details of the connection to this service.

CSCat20202

In the Line Card Management window, the Module Type attribute is incorrectly reported for OC-12 NLCs. It should be reported as OC-12 Single Mode Fiber.

Workaround: None.

CSCat19582

In the Service/Subscriber Connection window, the Service Type attribute on the Single Domain tab uses an old SCM service naming convention.

Workaround: The correct name mappings are as follows:

ATM = ATM

Bridged-Bridged = RFC 1483 Bridging

Bridged-Routed = RFC 1483 IRB

PPP-L2TP = L2TP

PPP-IP = PPPoA-SD

PTA-MD = IP Uplink

RFC 1483 = RFC 1483 Routing

CSCat18410

The Global Performance Logging button on the Chassis Configuration window does not turn on bandwidth utilization monitoring on ATM ports.

Workaround: Turn on bandwidth utilization manually from the Interface Performance window.

CSCat17425

If an RFC 1483 Routing service is decommissioned while there are subscribers connected to the service, the decommission action may fail and show the following error message: Updating ATM port bulk list result in error.

Workaround: Do not decommission a service while there are subscribers connected to it.

CSCat17727

It is possible that some SCM help files could be overwritten by the installation of another EM package onto the same CEMF server. In particular, the installation of Cisco DSL Manager overwrites the help files for some of the common windows used by both applications. The help file is still relevant for the window, but may link to other CDM help files instead of SCM files.

Workaround: None.

CSCat16899

The Username and Password fields should be separated. Currently these are combined into a single field, with Username and Password separated by a space.

Workaround: None.

CSCat17632

It is possible to delete connection templates, even if the template is being used by a subscriber connection.

Workaround: None. Use the Delete button on the Connection Template Configuration window to delete connection templates.

CSCat16770

Cisco IOS interaction scripts can time out under severe adverse network conditions.

Workaround: The default timeout setting is 60 seconds. You can change this by creating a timeout file that contains the new timeout value in seconds. Create the file in the directory <CEMFROOT>/config/perl. For example, the following command, executed as root, sets the timeout value to 120 seconds (where /opt/cemf is the default CEMF installation directory):

echo 120 > /opt/cemf/config/perl/timeout

CSCat18441

The Service/Subscriber Connection window requires that you use the Save button or the File > Save menu option to save attribute changes before selecting an action button. Otherwise, updated values are not used by the action. This is inconsistent with the operation of the Service Configuration windows, which automatically save changes when an action button is selected.

Workaround: Save changes before you select an action button.

CSCat16269

The Deployment Wizard incorrectly allows the deployment of objects directly beneath the root of a view. Deploying certain SCM objects incorrectly (such as Services or Subscribers) may cause operations to fail.

Workaround: Avoid deploying Service or Subscriber objects beneath the root of the Service or Subscriber views. Delete incorrectly deployed objects, and deploy them correctly.

CSCat16404

The Encapsulation Type options on the Service/Subscriber Connection window may not be appropriate for the selected service. For example, the options aal5mux ppp and aal5cisco ppp are available for connections to RFC 1483 Routing services.

Workaround: Ensure that the correct encapsulation type is selected.

CSCat17607

The status bar at the bottom of some SCM windows incorrectly displays the state of some objects as having no value.

Workaround: Determine the correct state of the objects by launching the corresponding management window (for example, NRP Management window for NRPs).

CSCat16042

In the IP Uplink Service Configuration window, it is possible to enter duplicate values in the Next Hop Gateway Key field, which could affect the stability of the service.

Workaround: Avoid entering duplicate values in this field. If a service was commissioned with a duplicate key, decommission the service and correct the error.

CSCat15857

The value of the Administration Status attribute on the Cisco 6400 NRP Management window cannot be changed.

Workaround: Use Cisco IOS to change the Administration Status of the card.

CSCat18672

In the RFC 1483 Routing Service Configuration window, if you select the Add button on the Service Uplink tab, this creates a new Service Uplink. However, selecting this button, causes unsaved changes to the service to be lost.

Workaround: Before you create a new Service Uplink, click the Save icon or the File > Save menu option to save any changes to the service.

CSCat16179

It is possible to connect a Subscriber to the same Service more than one time. Although this is usually not a logical action, SCM does not prevent it.

Workaround: Use the Service/Subscriber Disconnection window to disconnect additional connections.

CSCat19916

Data migration from SCM Release 1.x to SCM Release 2.0(1) may fail if all of the following conditions are true:

  • In SCM Release 1.x, there is an NRP object deployed with no IP address set in SCM.
  • The NRP is deployed in a slot that is empty on the actual Cisco 6400 chassis.
  • There is an NRP in another slot in the Cisco 6400 chassis, but there is no corresponding NRP object in SCM.

Workaround: In SCM Release 1.x, delete the NRP object and deploy a new NRP object that correctly matches the Cisco 6400 device configuration.

CSCat19936

The ATM Port management windows may not work correctly with ATM port objects migrated from SCM Release 1.x. Cisco 6400 IOS software includes a workaround for nonmigrated ATM port objects, but not for migrated ones.

Workaround: Open the Object Configuration window for the ATM Port object (right-click the ATM Port object, and select Tools > Open Object Configuration). Select snmpManageable, and enter the value 1 for the attribute snmp-varbinds-per-packet. Save this change and close the Object Configuration window.

CSCat19685

The Authentication Type attribute of an L2TP service may not be correctly migrated from SCM Release 1.x to SCM Release 2.0(1).

Workaround: Select the correct Authentication Type before you commission the service (also see CSCat19871).

SCM Release 2.0 Caveats

Table 4 lists known problems in this release of the SCM. Unless otherwise noted, there is no workaround.

Table 4   Open Caveats for SCM Release 2.0

Caveats Description

CSCdr34047

If you manually deploy a Cisco 6400 chassis and subsequently run CEMF autodiscovery over this range, this chassis appears two times.

CSCdr34055

It can take up to 5 minutes to detect that a card (such as an NRP or NLC) has been physically removed from the Cisco 6400 chassis (that is, an alarm condition appears in the Map Viewer application).

CSCdr34070

If you launch CEMF autodiscovery from the NSP object in a Cisco 6400 chassis, this categorizes all discovered network elements as children of the NSP in the Physical View.

CSCdr34493

When CEMF IP autodiscovery is run, NRPs can be discovered.

Each time autodiscovery is launched from a site, the physical view is populated with the respective shelves and the NRPs lying in that range underneath it, giving the impression that the NRPs are contained within the site, which is not correct. They should be either placed under the chassis or should not appear at all until the chassis is commissioned.

CSCdr34504

Occasionally, the deconfiguration of the PPPoE base configuration on the SSG Configuration window fails. If this happens, retry the deconfiguration.

CSCdr34648

It is possible to delete connection templates using the CEMF Map Viewer Delete menu while subscribers are still connected using this connection template.

Workaround: Before you delete the connection template object, ensure that all subscribers are disconnected first.

Documentation Changes

A new feature, the Capacity Monitoring tool, appears in the Cisco 6400 Service Connection Manager software Release 2.1(1). The information that describes this new feature and explains how to use it will be added to the next revision of the Cisco 6400 Service Connection Manager User Guide (OL-0569-02) and then removed from this release note.

PVC Management and Capacity Monitoring Tool

The Permanent Virtual Connection (PVC) Management and Capacity Monitoring tool allows you to better manage your PVC bandwidth resources by providing the information required to monitor the VPC/VCC allocation and maximize memory allocation for the Cisco 6400 Universal Access Concentrator (UAC).


Note   The Management and Capacity Monitoring tool is only compatible with releases of Cisco IOS Release 12.1(4)DB and later that contain the show atm input-xlate-table and show atm input-xlate-table inuse commands for the NSP. Refer to the Cisco 6400 Software Configuration and Command Reference Guide for more information about ITT enhancements.

The Cisco 6400 Service Connection Manager software's new Capacity Monitoring tool allows you to view all Input Translation Table (ITT) usage, which includes the:

This tool helps you to closely control PVC memory allocation on the Cisco 6400 Node Switch Processor (NSP). ITT memory size may be limited and blocks may be large, so ITT allocation space should be monitored closely.

Cisco IOS Input Translation Table

The Input Translation Table is a hardware data structure used in the Cisco 6400 NSP for handling incoming cells. The ITT table consists of entries that are allocated in contiguous blocks for Virtual Circuit (VC) switching, and each block is dedicated to a Virtual Path Identifier (VPI) on an interface.

The entire NSP consists of a single ITT, which is organized in two banks of 32,000 entries each. This limits the use of large Virtual Channel Identifier (VCI) values and also limits the distribution of VCIs on VPIs as the number of VCs approach 32,000. When an additional VC is added to a VPI that requires a larger block size than the current block, the current block is copied to a new larger block, and the original block is freed. This leaves a series of small unused blocks. As a result, ITT memory is fragmented. The ITT blocks grow to accommodate higher VCI values for a specific port or VPI, but ITT space is not returned unless the entire ITT is full.

The ITT enhancements provide new NSP functions to minimize fragmentation and enable the NSP to automatically determine the minimum ITT block size required to support the PVCs configured for each interface and VPI.

Common Terms

The following list describes common terms used for the Capacity Monitoring tool:
