Introduction

The Cisco Content Services Gateway adds accounting and content-billing features to the Cisco Catalyst 6500 switch and the Cisco 7600 router platforms. The CSG typically is located at the edge of an ISP network. It provides IP flow accounting and content accounting by examining HTTP request URLs and header information. The CSG Service Manager (CSG SM) is a CSG-management tool that provides powerful fault-management, configuration, and troubleshooting functionality. Additionally, the CSG SM gathers user-name and usage statistics, and enables differentiated billing for individual transactions. In so doing, the CSG SM supports mobile operators who are migrating their wireless service delivery networks from second-generation (2G) circuit-based traffic to 2.5G- and 3G-based services.

The CSG SM includes:

Inventory Manager—Manages and display device group information.

Service Manager—Works with device groups for service activation.

Troubleshooting Engine—Troubleshoots CSG devices.

You can use the CSG SM to provision service-activation features for CSG Releases 5.3 through 5.9, 6.4, and 7.1.

The CSG SM is part of the Mobile Wireless Center (MWC) for Cisco Mobile Exchange, a suite of element-management applications that provide configuration and fault-monitoring capabilities to mobile wireless operators. MWC for Cisco Mobile Exchange applications complement the CiscoWorks LAN Management Solution (LMS) to provide end-to-end management of the Cisco Mobile Exchange. The Release Notes for Mobile Wireless Center for Cisco Mobile Exchange provide information on these tools. See Product Documentation and Related Documentation, for information on accessing the electronic version of this document on the Cisco website.

The LMS 2.5.1 includes:

Common Services 3.0.3 with CiscoView 6.1.2

Resource Manager Essentials 4.0.3

Campus Manager 4.0.3


Note The LMS 2.5.1 also includes Internet Performance Monitor (IPM) 2.6 and Device Fault Manager 2.0.3, but these applications are not required for the MWC for Cisco Mobile Exchange.


Refer to the Release Notes for Mobile Wireless Center for Cisco Mobile Exchange Release for this release, http://www.cisco.com/en/US/products/ps6401/prod_release_notes_list.html, for information on MWC for Cisco Mobile Exchange and the LMS requirement.

Table 1 Caveats Resolved With This Release

Bug ID
Summary

CSCin82636

The command extractCsgConfigByType() fetches some extra configlets. This has been fixed.

CSCsb38888

Delete commands for Interface Aware were not being properly generated. This has been fixed.

CSCsb45653

The Config display took more than a minute to complete. This has been fixed.

CSCsb46254

The Interface Aware table did not show records if a dummy CSG existed. This has been fixed.

CSCsb46286

Unsupported commands appeared to be available. For certain commands to be supported, both the CSG and IOS versions had to support the commands. The CSG SM checked the CSG version only and provided GUI screens on that basis. This has been fixed.

CSCsb87613

Only one user could view syslogs at a time. Other user windows showed blank displays. This has been fixed.

CSCsb87669

Show command windows opened inside existing windows, not in new windows. This has been fixed.


Open Caveats and Workarounds

Table 2 lists the ID number, summary, and any available workaround for each open caveat in this release.


Note To obtain updated information about open caveats and workarounds, access the Cisco Software Bug Toolkit at http://www.cisco.com/cgi-bin/Support/Bugtool/home.pl. You will be prompted to log in to Cisco.com.


Table 2 Open Caveats and Workarounds 

Bug ID
Summary
Workaround

CSCsb32820

The CSG SM does not automatically control the size of the cmxTe.log file. File size can increase rapidly if you have enabled devices for debugging and viewing Syslogs. If this file becomes bigger than 10MB, the following warning message appears:

The log file: /var/adm/CSCOpx/log/
cmxTe.log has exceeded the maximum recommended file size; performance might be impacted. To setup an automation log rotation facility, refer to: http://www.cisco.com/en/US/products/ps6401/prod_release_notes_list.html

Use the logrot utility against /var/tmp/CSCOpx/log/cmxTe.log.

You may wish to implement this action in a cronjob.

You can access the logrot utility at http://www.cisco.com/en/US/
products/sw/cscowork/ps3996/
products_user_guide_chapter
09186a008022f958.html#wp271846
.

CSCsb41531

The CSG SM Stop Debug function does not show an error when its associated RME job fails.

If login credentials were changed while debug commands were running from the CSG SM, Telnet to the device and execute the show debug command from Enable mode.

Execute the no debug command to disable debugging.

CSCsb45729

An RME job stopped during CSG stress testing

None.

CSCsb52549

The CSG config display times out after long runs lacking a timeout.

You can set maximum RME concurrency to five threads. However, this probably will degrade overall system performance (that is, job elapsed time).

CSCsb94740

The CSG SM gives false information about Reassign Quota Server and Ack Error.

Use the recommended version of IOS with CSG 6.2, which is 12.2(18)SXE. If you choose to use an IOS version that does not support these commands, ignore check boxes in the GUI.


Known Problems


Note To obtain updated information about known problems, you can access the Cisco Software Bug Toolkit at http://www.cisco.com/cgi-bin/Support/Bugtool/home.pl. You will be prompted to log into Cisco.com.


The CSG Service Manager provides a Graphical User Interface (GUI) for service activation of CSG devices. Service activation includes configuration tasks that you perform frequently (for example, in daily operations). Network preparation and service preparation tasks occur less frequently, and you apply them through the command-line interface (CLI).

One limitation of this design occurs when deleting user groups that have accounting configurations. An accounting configuration is a service-preparation task performed from the CLI, as in the following example:

!
ip csg accounting ACCT12
 user-group MAIN
 agent 10.1.0.1 3333 2
 agent 10.1.0.2 3333 3
 agent 10.1.0.3 3333 4
 agent 10.1.0.4 3333 1
 inservice
!

If an accounting configuration has been applied to a user group that is defined in the Service Manager, you must first use CLI commands to delete the accounting configuration before deleting the user group in the GUI.

Review Prerequisites for Configuring CSG Devices, for specific requirements relating to versions, switches, and cards.

You can find further information about all supported devices on Cisco.com at: http://www.cisco.com/univercd/cc/td/doc/product/rtrmgmt/cw2000/mgt_pix/fwmc_1_3/px_sd_13.htm

Prerequisites for Configuring CSG Devices

To use the CSG SM to configure a CSG device, perform the following required actions. The optional actions that follow deal with configurations that may exist in the device, but that are not addressed by the CSG SM.

Required—Use of the CSG SM requires that you:

Ensure that the device is one of those shown in Table 3.

Ensure that the IOS version of the Catalyst switch matches the CSG version. The IOS releases supported by the MWC for CMX 4.0 are 12.2(18)SXD(x) and 12.2(18)SXE(x). CSG Versions 5.3 through 5.8 run on a Catalyst Switch with a Sup 2 card running the 12.2(18)SXDx.

Ensure that all CSG cards are running the same CSG image version. Each Catalyst switch can have a maximum of four CSG cards.

Enable Simple Network Management Protocol (SNMP) so that the CSG SM can check the version of the device.

Complete installation in the correct installation order. See Installation Order for more information.

Ensure that the CSG device to be configured has been added to the Device Credentials Repository (DCR) and is managed by the RME Inventory Manager.

For more information on the RME inventory function, see the section titled "Adding and Troubleshooting Devices Using Device Management" in the User Guide for Resource Manager Essentials 4.0.3 (With LMS 2.5.1) at http://cisco.com/en/US/products/sw/cscowork/ps2073/
products_user_guide_book09186a008055b137.html
. The specific section is here.

Optional—While the CSG SM does not address the following configuration issues, you may wish to take these actions as well:

Complete all network preparation, such as configuring the required VLANs, VRFs, virtual templates, AAA servers, RADIUS server, and interface configurations, on all CSG devices.

Complete all service preparation, such as enabling server farms and charging related configurations.

Configure load balancing.
