This section describes the resolved caveats in Cisco SCA BB Release 3.7.5 that relate to the general issues pertaining to the Cisco SCA BB Console.
CSCsy96654
When an attack was detected while setting an attack detector to block a specific TCP port, the block rule was applied for all the TCP ports other than the port for which the attack detector was defined.
This issue is resolved.
CSCtj19964
In the Cisco SCA BB Console, when the Generate the Virtual Links Usage RDRs check box was unchecked, Virtual Link Usage RDRs were generated until the VLink Mode Enable setting was disabled.
This issue is resolved.
CSCtj49052
In the Network Navigator tab of the Cisco SCA BB Console, when users right-clicked the corresponding SCE device and selected the Online Status option, the bandwidth value of the SCE device was displayed as a negative value.
This issue is resolved.
CSCts52096
In the Edit Subscriber window, the Subscriber Package drop-down list contained a blank space between the each package ID.
This issue is resolved.
CSCts97290
in the Quota Bucket Profile Editor window, due to low resolution, users were not able to transfer services between the Services tab and the Time frame tabs because the buttons with arrow were not visible.
This issue is resolved.
CSCtx07240
When the virtual channels for virtual links were created through the CLI, duplicate CLIs were created in the configuration file.
This issue is resolved.
CSCtx48424
From the Cisco SCA BB Console, when a default virtual link value was set for a newly added global controller under the virtual links, it failed in the downstream direction.
This issue is resolved.
CSCtx48498

This issue is resolved.
CSCtx95224
The authorised users were unable to import the sce-url-database.
This issue is resolved.
Open Caveats, Release 3.7.5
This section describes the open caveats in Cisco SCA BB Release 3.7.5.
CSCtq80422
In the Cable Modem Termination System (CMTS), when the Virtual Link Manager (VLM) in the vlink.cfg file of the Cisco Subscriber Manger is enabled, all the virtual links in the CMTS do not get provisioned from the Subscriber Manager to Cisco SCE.
Workaround:
No known workaround.
CSCty73869
After enabling the virtual link mode, when a virtual link was created manually using the virtual-links index <index> name <name> direction [upstream | downstream] command, and a policy applied from Cisco SCA BB with the Keep Virtual Link rate limits unchanged button selected, the policy did not get applied and some of the virtual links were getting deleted.
Workaround:
After enabling the virtual link mode, when a virtual link is manually created using the virtual-links index <index> name <name> direction [upstream | downstream] command, ensure that you create a virtual channel index for the corresponding virtual link using the virtual-links channel index <index> name <name> parent-virtual-link index <index> direction [upstream | downstream] command.

Protocol Pack
This section describes the open caveats in Cisco SCA BB Release 3.7.1 that relate to Protocol Pack:
CSCtt70660
A capacity degradation of 1.76 percentage is observed on Cisco SCE 8000 with SCE Release 3.7.1, when compared to Cisco SCE 8000 with SCE Release 3.7.0.
The fix for this issue will be available in future Protocol Pack releases.
Workaround:
No known workaround.
CSCts23380
A capacity degradation of 5.02 percentage is observed on Cisco SCE 2000 with SCE Release 3.7.1, when compared to Cisco SCE 2000 with SCE Release 3.7.0.
The fix for this issue will be available in future Protocol Pack releases.
Workaround:
No known workaround.
Traffic Processing
This section describes the open caveats in Cisco SCA BB Release 3.7.1 that relate to traffic processing:
•
General
This section describes the open caveats in Cisco SCA BB Release 3.7.1 that relate to general issues concerning traffic processing.
CSCtq12796
In the Anonymous Group Manager GUI tool, the values for Template ID, Package ID, UpVlink, and DownVlink are restricted to 99. But in SCE, the values for Template ID and Package ID are restricted to 4999, and values for UpVlink, DownVlink are restricted to 1023. The values supported should be same in both the GUI and the SCE.
Workaround:
No known workaround.
CSCtq12777
Failed to connect to multiple Subscriber Managers by using the Subscriber Manager GUI in Cisco SCA BB Console.
When connected to a Subscriber Manager, if you try to connect to a second Subscriber Manager, the first Subscriber Manager gets replaced with the second Subscriber Manager.
Workaround:
No known workaround.
CSCtq15400
If two zeroes are added to a new Protocol ID to avoid ID duplication, the issue gets resolved only after two attempts. Also, even if you use a new ID in the second attempt, the ID you entered during the first attempt is saved.
For example, if the new Protocol ID is 4200, the first attempt fails. In the second attempt, even if you use a new ID (4211), 4200 is saved as the new Protocol ID.
Workaround:
If you use two zeroes, enter the same value during both the attempts.
CSCsx75003
The PQI installation process should reserve more disk space on SCE 2000.
The PQI installation process fails because of insufficient disk space on the SCE 2000. The SCE file system containing a lot of files consumes the disk space.
Workaround:
Manually remove the unnecessary files from the SCE file system.
CSCsz59158
The SCE 8000 MGBE might crash when you apply a PQB that contains1000 global controllers.
If a policy with 1000 global controllers is not applied correctly after a reload, the SCE might run out of memory and the box may crash.
Workaround:
There is no known workaround.
CSCtq99331
When applying policies for different templates, if the virtual link is enabled, an error similar to this appears:
+ 6/16/11 5:41:17 PM IST | ERROR | Failed to apply service configuration at "SCE device [10.78.241.106]": Error Code = 1, Description: "Input key should be number between 0 to 4,294,967,295More info: in func 'CmdlLut::overwriteManyCfg', lutName='GT_LUT_VIRTUAL_upLinkIdx2AppAGCIdx', key[0]='-65536', value[0]='0', numVariables=3..", Detailed: "" (LUT_overwriteManyCfg:{key=[Ljava.lang.String;@21f572, slot=0, lutName=GT_LUT_VIRTUAL_upLinkIdx2AppAGCIdx, value=[Ljava.lang.String;@21f579})Workaround:
Disable the virtual link in SCE using the no virtual link CLU command before applying the new configuration.
Traffic Classification
This subsection describes the open caveats in Cisco SCA BB Release 3.7.1 that relate to traffic classification.
CSCsd81077
The same flow can be classified into different services, depending on a zone configuration that seems unrelated. This occurs after you define a new port-based protocol and then create a new service, adding a service element with the new protocol and a non-default zone to the service. Flows that match the new protocol but do not match the zone of the service element are now mapped to the Default Service.
Complete these steps (The unexpected flow classification occurs at step 6):
1.
2.
3.
4.
5.
6.
7.
Workaround:
Add the service element <New port-based protocol, Initiated by either side, *, *> to an existing service. (You can also define a new service for this purpose.) After you do that, transactions using the specific protocol but with network IP addresses that do not match the specific zone, go to the less specific service.
For the example given above, add the service element <doom2, Initiated by either side, *, *> to the Generic TCP service.
CSCsi46655
When SCA BB is deployed in an environment where it is required to analyze traffic in VLANs/VPNs with overlapping IP addresses, some of its capabilities, which rely on uniqueness of IP addresses in the network, do not function:
•
•
Many reports in the following categories rely on IP uniqueness:
•
•
•
•
•
•
N/A
In Cisco SCA BB Release 3.0.0, the limit for the number of items in the HTTP URL list was increased from 10,000 to 100,000. Adding more than 10, 000 items to the list affects flow capacity. Using 100,000 list items can degrade system capacity by up to 50,000 flows compared with the capacity numbers presented in Cisco SCA BB Release 3.1.5.
Traffic Accounting and Reporting
This subsection describes the open caveats in Cisco SCA BB Release 3.7.1 that relate to traffic accounting and reporting.
CSCsb60539
When you enable TUR RDRs for RTSP, the session ID field in RTSP TUR contains incorrect values because of the extraction of the session ID from the wrong fields in the RTSP packets.
CSCsd74145
Skype call detection is performed by using a heuristic analysis of Skype traffic, which makes call detection in Skype less accurate than in other VoIP protocols, and introduces the following limitations:
•
•
When looking at aggregated information and reports, these limitations are of less significance, because of averaging and aggregation of large number of calls.
N/A
The number of concurrent sessions reported by the SCE application can sometimes be lower than the number of open flows in the SCE platform counters. In certain services, such as VoIP and FTP, a single session consists of more than one flow. The SCE platform counters track flows, rather than sessions, and therefore, may show higher values. In addition, flows with no payload are tracked by the SCE platform counters, but not by the SCE application counters.
N/A
The following MIB counters and fields in the Link Usage RDR and the Package Usage RDR require clarification:
•
•
•
•
•
Traffic Control
This subsection describes the open caveats in SCA BB Release 3.7.1 that relate to traffic control.
CSCsg08507
When working in the Quota Manager with a Number of Sessions bucket and with dosage less than quota, when the dosage given to the SCE is fully used, a new session is blocked even if the quota is available in the Quota Manager. This issue occurs because there are no Quota Threshold RDRs. The (blocked) session triggers a Threshold RDR (and threshold notification to the Quota Manager) and the next session succeeds.
For example, if the dosage size is five sessions, every sixth session is blocked and fails.
Workaround:
Always set the dosage size equal to the quota size when working with a Number of Sessions bucket.
Cisco SCA BB Console
This section describes the open caveats in Cisco SCA BB Release 3.7.1 that relate to the Cisco SCA BB Console:
General
This subsection describes the open caveats in Cisco SCA BB Release 3.7.1 that relate to general issues concerning the SCA BB console.
CSCsa91254
Choosing Save from any tool in the SCA BB Console saves the current open PQB configuration file, even if that is not the appropriate file type for the tool.
CSCsv62305
Upgrading a device via the GUI or API also upgrades the console. If you upgrade a Protocol Pack via an SPQI file, the console is upgraded as well with the new signatures. Applying it to a device that was not upgraded as well may fail.
CSCsy81384
The Apply function fails with an error, when updating the HTTPS redirection URL as part of redirection set in the GUI.
N/A
SCA BB allows users to navigate from a report to the corresponding service configuration entity. For example, right-clicking a service name in the report legend can take you to the service definition in the Service Configuration Editor. However, the system can navigate only to the PQB file that is currently open in the SCA BB console.
N/A
Service and package names are not refreshed automatically in the Reporter after applying changes in the SCA BB Console.
Workaround:
Manually refresh the templates.
Installation
This subsection describes the open caveats in Cisco SCA BB Release 3.7.1 that relate to installation of the Cisco SCA BB console.
CSCsa94964
If you run the uninstaller when the Cisco SCA BB Console is open, the uninstallation fails without displaying any warning.
SCA BB fails to install on top of an existing installation.
Workaround:
Close the Cisco SCA BB Console before starting uninstallation process.
Uninstall the SCA before reinstalling it.
CSCsc32003
When the application is uninstalled, the Network Navigator configuration (sites and devices) is not deleted, instead it is kept for future Cisco SCA BB Console installations.
Workaround:
To clear these settings, manually delete the C:\Documents and Settings\<username>\.scasbb300 folder.
Network Navigator
This subsection describes the open caveats in Cisco SCA BB Release 3.7.1 that relate to the Network Navigator.
CSCsa95657
The console permits the creation of two (or more) identical devices with the same name or the same IP address.
Workaround:
Remove all identical devices.
CSCsc49774
Cisco SCA BB failed to connect to a device when the IP address provided is of a different device type (for example, when adding an SCE the IP address of an SM is provided). The error message displayed does not correctly identify the problem.
CSCsv55906
When you upgrade Cisco SCA BB from Release 3.1.7 to Release 3.5.0, the network configuration is not automatically imported. You export, and then import. After the import is complete, two default sites appear in the window.
N/A
Concurrent operations, such as applying a configuration and extracting a support file simultaneously, on the same SCE platform are not supported. Wait for one operation to finish before beginning a second operation.
N/A
When applying a service configuration to the SCE, the Network Navigator also updates the relevant CM with service configuration values, such as service and package names, that are later shown by the Reporter.
The Network Navigator takes the CM IP address from the SCE platform RDR-formatter definitions. With certain topologies (such as in a NAT environment), this IP address might not be accessible by the Network Navigator, and a different CM IP address should be used. The engage.ini preferences file can be used to remap CM IP addresses from the SCE platform RDR-formatter definitions to IP addresses to which the Network Navigator can connect.
The "dc.ip.remap.<n>=<address1>,<address2>" property in the engage.ini file defines a mapping between IP addresses. For example, the entry "dc.ip.remap.1=10.1.12.224,212.194.11.27" means that if the SCE RDR-formatter destination is 10.1.12.224, the Network Navigator should update the CM at 212.194.11.27.
The engage.ini file can be found and edited at the following location:
<scas-bb-console-installation>/plugins/policy.contribution/config
which usually maps to:
C:\Program Files\Cisco SCAS\SCAS BB Console 3.0.0\plugins\policy.contribution_1.0.0\config\engage.ini
Service Configuration Editor
This subsection describes the open caveats in Cisco SCA BB Release 3.7.1 that relate to the Service Configuration Editor.
CSCsx17491
PQB files that were created by using Cisco SCA BB releases earlier than Release 3.0 might not open in Cisco SCA BB Release 3.5.0 and later.
Workaround:
Install Cisco SCA BB 3.1.7, open the PQB and save it to the disk. You can then open it in Cisco SCA BB Release 3.5.0 and later.
Reporter
This subsection describes the open caveats in Cisco SCA BB Release 3.7.1 that relate to the Reporter.
CSCsy26498
The Reporter filters the data for HTTP-related reports based on the services that belong to the HTTP protocol family. Services that are defined by flavors without a specific protocol are not included in the reports. The HTTP service based on the URL list is not displayed in the HTTP-related reports.
Workaround:
Add a service element for the service that includes flavor and HTTP protocol.
CSCta54572
All the reports that show average bandwidth per subscriber are not accurate.
The three reports that show the average bandwidth per subscriber are:
•
•
•
These reports sum up the number of subscribers from all RDRs per hour instead of the average number of subscribers per hour, and divide the total bandwidth with this number.
For example:
If RDR is per minute and there are 1000 active subscribers, the report divides the total bandwidth in 60,000 (1000 * 60 minutes).
CSCtc31584
Average or global subscriber bandwidth reports should not allow filter by service.
The reports for Average Subscriber Bandwidth and Tunneled IPv6 Average Subscriber Bandwidth with filter by services using the right pane generate inaccurate results.
Workaround:
When generating reports for Average subscriber bandwidth and Tunneled IPv6 Average Subscriber Bandwidth, do not filter by services using the right pane.
CSCtc31659
The IPv6 vs IPv4 Bandwidth Comparison report is incorrect when using aggregation.
This report is the result of the union between two queries operated on RPT_LUR and RPT_GUR simultaneously.
Data must be merged but only the RPT_LUR table supports aggregations, so the report produces incorrect results.
Workaround:
Disable the aggregation for the RPT_LUR table.
Configuration Management
This section describes the open caveats in Cisco SCA BB Release 3.7.1 that relate to configuration management.
Service Configuration API
This subsection describes the open caveats in Cisco SCA BB Release 3.7.1 that relate to the Service Configuration API.
N/A
Backward compatibility with SCA BB 2.5 Service Configuration API.
Package and class name changes: The Service Configuration Management API has changed in Cisco SCA BB Release 3.0.0, to accommodate new product naming conventions. Nevertheless, the older API classes and methods can still be used.
Note
CSV file format changes: SCA BB introduces a new format for CSV files of HTTP URL lists. For backward compatibility, SCA BB 3.0.0 Service Configuration API allows importing CSV files of HTTP URLs in the old Cisco SCA BB Release 2.5.0. formats.
Cisco Service Control Application for Broadband Release 3.7.0
This section describes the new features, and resolved and open issues pertaining to Cisco SCA BB Release 3.7.0:

This issue is resolved. You can now enable WinnyP from Cisco SCA BB Console.
CSCtl03931
The Global Controller unit conversion was not accurate.
In Cisco SCA BB Console, under Global Controller Settings, the unit for the rate limit was displayed in KB/s. The value displayed in the Global Policy screen, was converted to KB/s by dividing the MB/s value by 1000 rather than by 1024.
This issue is resolved.
CSCtl19613
Failed to anonymize IP address for RDRs other than HTTP.
This issue is resolved. A new check box is introduced to enable and disable anonymization in other RDRs such as Blocking RDR, Spam RDR, and Flow Start RDR.
CSCtn65110
The Subscriber Manager GUI failed to open from Cisco SCA BB console when a Collection Manager IP address was configured in the p3sm.cfg file.
This issue is resolved.
CSCtq12506
An error was displayed when trying to load a PQB file or retrieve a PQB file from the SCE in Cisco SCA BB Console.
An internal error occurred during: "Opening Service Configuration File".org.eclipse.emf.ecore.resource.Resource$IOWrappedException: The entity name must immediately follow the '&' in the entity reference.This error was caused because the name of a Zone contained the "&" character.
This issue is resolved. You cannot include the "&" character in the Flavor and Zone names.
Reporter
This subsection describes the resolved caveats in Cisco SCA Reporter Release 3.7.0.
CSCtn64715
Large number of malicious sessions were seen on SCA Reporter.

For the example given above, add the service element <doom2, Initiated by either side, *, *> to the Generic TCP service.

When SCA BB is deployed in an environment where it is required to analyze traffic in VLANs/VPNs with overlapping IP addresses, some of its capabilities, which rely on uniqueness of IP addresses in the network, do not function:
•
•
Many reports in the following categories rely on IP uniqueness:
•
•
•
•
•
•
N/A
In Cisco SCA BB Release 3.0.0, the limit for the number of items in the HTTP URL list was increased from 10,000 to 100,000. Adding more than 10, 000 items to the list affects flow capacity. Using 100,000 list items can degrade system capacity by up to 50,000 flows compared with the capacity numbers presented in Cisco SCA BB Release 3.1.5.
Traffic Accounting and Reporting
This subsection describes the open caveats in Cisco SCA BB Release 3.7.0 that relate to traffic accounting and reporting.
CSCsb60539
When you enable TUR RDRs for RTSP, the session ID field in RTSP TUR contains incorrect values because of the extraction of the session ID from the wrong fields in the RTSP packets.
CSCsd74145
Skype call detection is performed by using a heuristic analysis of Skype traffic, which makes call detection in Skype less accurate than in other VoIP protocols, and introduces the following limitations:
•
•
When looking at aggregated information and reports, these limitations are of less significance, because of averaging and aggregation of large number of calls.
N/A
The number of concurrent sessions reported by the SCE application can sometimes be lower than the number of open flows in the SCE platform counters. In certain services, such as VoIP and FTP, a single session consists of more than one flow. The SCE platform counters track flows, rather than sessions, and therefore, may show higher values. In addition, flows with no payload are tracked by the SCE platform counters, but not by the SCE application counters.
N/A
The following MIB counters and fields in the Link Usage RDR and the Package Usage RDR require clarification:
•
•
•
•
•
Traffic Control
This subsection describes the open caveats in SCA BB Release 3.7.0 that relate to traffic control.
CSCsg08507
When working in the Quota Manager with a Number of Sessions bucket and with dosage less than quota, when the dosage given to the SCE is fully used, a new session is blocked even if the quota is available in the Quota Manager. This issue occurs because there are no Quota Threshold RDRs. The (blocked) session triggers a Threshold RDR (and threshold notification to the Quota Manager) and the next session succeeds.
For example, if the dosage size is five sessions, every sixth session is blocked and fails.
Workaround:
Always set the dosage size equal to the quota size when working with a Number of Sessions bucket.
Cisco SCA BB Console
This section describes the open caveats in Cisco SCA BB Release 3.7.0 that relate to the Cisco SCA BB Console:
General
This subsection describes the open caveats in Cisco SCA BB Release 3.7.0 that relate to general issues concerning the SCA BB console.
CSCsa91254
Choosing Save from any tool in the SCA BB Console saves the current open PQB configuration file, even if that is not the appropriate file type for the tool.
CSCsv62305
Upgrading a device via the GUI or API also upgrades the console. If you upgrade a Protocol Pack via an SPQI file, the console is upgraded as well with the new signatures. Applying it to a device that was not upgraded as well may fail.
CSCsy81384
The Apply function fails with an error, when updating the HTTPS redirection URL as part of redirection set in the GUI.
N/A
SCA BB allows users to navigate from a report to the corresponding service configuration entity. For example, right-clicking a service name in the report legend can take you to the service definition in the Service Configuration Editor. However, the system can navigate only to the PQB file that is currently open in the SCA BB console.
N/A
Service and package names are not refreshed automatically in the Reporter after applying changes in the SCA BB Console.
Workaround:
Manually refresh the templates.
Installation
This subsection describes the open caveats in Cisco SCA BB Release 3.7.0 that relate to installation of the Cisco SCA BB console.
CSCsa94964
If you run the uninstaller when the Cisco SCA BB Console is open, the uninstallation fails without displaying any warning.
SCA BB fails to install on top of an existing installation.
Workaround:
Close the Cisco SCA BB Console before starting uninstallation process.
Uninstall the SCA before reinstalling it.
CSCsc32003
When the application is uninstalled, the Network Navigator configuration (sites and devices) is not deleted, instead it is kept for future Cisco SCA BB Console installations. \
Workaround:
To clear these settings, manually delete the C:\Documents and Settings\<username>\.scasbb300 folder.
Network Navigator
This subsection describes the open caveats in Cisco SCA BB Release 3.7.0 that relate to the Network Navigator.
CSCsa95657
The console permits the creation of two (or more) identical devices with the same name or the same IP address.
Workaround:
Remove all identical devices.
CSCsc49774
Cisco SCA BB failed to connect to a device when the IP address provided is of a different device type (for example, when adding an SCE the IP address of an SM is provided). The error message displayed does not correctly identify the problem.
CSCsv55906
When you upgrade Cisco SCA BB from Release 3.1.7 to Release 3.5.0, the network configuration is not automatically imported. You export, and then import. After the import is complete, two default sites appear in the window.
N/A
Concurrent operations, such as applying a configuration and extracting a support file simultaneously, on the same SCE platform are not supported. Wait for one operation to finish before beginning a second operation.
N/A
When applying a service configuration to the SCE, the Network Navigator also updates the relevant CM with service configuration values, such as service and package names, that are later shown by the Reporter.
The Network Navigator takes the CM IP address from the SCE platform RDR-formatter definitions. With certain topologies (such as in a NAT environment), this IP address might not be accessible by the Network Navigator, and a different CM IP address should be used. The engage.ini preferences file can be used to remap CM IP addresses from the SCE platform RDR-formatter definitions to IP addresses to which the Network Navigator can connect.
The "dc.ip.remap.<n>=<address1>,<address2>" property in the engage.ini file defines a mapping between IP addresses. For example, the entry "dc.ip.remap.1=10.1.12.224,212.194.11.27" means that if the SCE RDR-formatter destination is 10.1.12.224, the Network Navigator should update the CM at 212.194.11.27.
The engage.ini file can be found and edited at the following location:
<scas-bb-console-installation>/plugins/policy.contribution/config
which usually maps to:
C:\Program Files\Cisco SCAS\SCAS BB Console 3.0.0\plugins\policy.contribution_1.0.0\config\engage.ini
Service Configuration Editor
This subsection describes the open caveats in Cisco SCA BB Release 3.7.0 that relate to the Service Configuration Editor.
CSCsx17491
PQB files that were created by using Cisco SCA BB releases earlier than Release 3.0 might not open in Cisco SCA BB Release 3.5.0 and later.
Workaround:
Install Cisco SCA BB 3.1.7, open the PQB and save it to the disk. You can then open it in Cisco SCA BB Release 3.5.0 and later.
Reporter
This subsection describes the open caveats in Cisco SCA BB Release 3.7.0 that relate to the Reporter.
CSCsy26498
The Reporter filters the data for HTTP-related reports based on the services that belong to the HTTP protocol family. Services that are defined by flavors without a specific protocol are not included in the reports. The HTTP service based on the URL list is not displayed in the HTTP-related reports.
Workaround:
Add a service element for the service that includes flavor and HTTP protocol.
CSCta54572
All the reports that show average bandwidth per subscriber are not accurate.
The three reports that show the average bandwidth per subscriber are:
•
•
•
These reports sum up the number of subscribers from all RDRs per hour instead of the average number of subscribers per hour, and divide the total bandwidth with this number.
For example:
If RDR is per minute and there are 1000 active subscribers, the report divides the total bandwidth in 60,000 (1000 * 60 minutes).
CSCtc31584
Average or global subscriber bandwidth reports should not allow filter by service.
The reports for Average Subscriber Bandwidth and Tunneled IPv6 Average Subscriber Bandwidth with filter by services using the right pane generate inaccurate results.
Workaround:
When generating reports for Average subscriber bandwidth and Tunneled IPv6 Average Subscriber Bandwidth, do not filter by services using the right pane.
CSCtc31659
The IPv6 vs IPv4 Bandwidth Comparison report is incorrect when using aggregation.
This report is the result of the union between two queries operated on RPT_LUR and RPT_GUR simultaneously.
Data must be merged but only the RPT_LUR table supports aggregations, so the report produces incorrect results.
Workaround:
Disable the aggregation for the RPT_LUR table.
Configuration Management
This section describes the open caveats in Cisco SCA BB Release 3.7.0 that relate to configuration management.
Service Configuration API
This subsection describes the open caveats in Cisco SCA BB Release 3.7.0 that relate to the Service Configuration API.
N/A
Backward compatibility with SCA BB 2.5 Service Configuration API.
Package and class name changes: The Service Configuration Management API has changed in Cisco SCA BB Release 3.0.0, to accommodate new product naming conventions. Nevertheless, the older API classes and methods can still be used.
Note
CSV file format changes: SCA BB introduces a new format for CSV files of HTTP URL lists. For backward compatibility, SCA BB 3.0.0 Service Configuration API allows importing CSV files of HTTP URLs in the old Cisco SCA BB Release 2.5.0. formats.
