1 Overview of the Cisco Service Control Solution
This section introduces the components of the Cisco Service Control solution and gives a high-level explanation of the entire installation process.
Cisco Service Control Components
The Cisco Service Control solution consists of five main components:
•
Cisco Service Control Engine (SCE) platform—A flexible, powerful, and dedicated network-usage monitor that is custom-built to analyze and report on network transactions at the application level.
For complete information about the installation and initial configuration of the Cisco SCE platform, see the Cisco SCE Platform Installation Guides and Configuration Guides.
•Cisco Service Control Application for Broadband (SCA BB)—An application that creates a service configuration file containing settings for traffic classification, accounting, and reporting, and applies it to a Cisco SCE platform. Cisco SCA BB provides tools to automate the distribution of these configuration files to Cisco SCE platforms. This simple, standards-based approach makes it easy to manage multiple devices in a large network.
For complete information about the installation and operation of Cisco SCA BB, see the Cisco Service Control Application for Broadband (SCA BB) User Guide.
•Service Control Management Suite (SCMS) Subscriber Manager—A middleware software component used when dynamic binding of subscriber information and policies is required. The Subscriber Manager manages subscriber information and provisions it in real time to multiple Cisco SCE platforms. The Subscriber Manager stores subscriber policy information internally, and acts as a stateful bridge between the authentication, authorization, and accounting (AAA) system (such as RADIUS and DHCP) and the Cisco SCE platforms.
For more information about the installation and operation of the Subscriber Manager, see the Cisco Service Control Management Suite Subscriber Manager User Guide.
Quota Manager is an optional component of the Subscriber Manager. It enables Cisco Control solution providers to manage subscriber quota across subscriber sessions with a high degree of flexibility.
For more information about the installation and operation of the Quota Manager, see the Cisco Service Control Management Suite Quota Manager User Guide.
Virtual Link Manager (VLM) is a component of the Subscriber Manager that enables Cisco Service Control solution providers to monitor and control individual subscriber links separately. For this, VLM creates a single policy with tier-differentiated packages, as also a number of virtual links, and then assigns subscribers to these virtual links. For more information, see the Cisco Service Control for Managing Remote Cable MSO Links Solution Guide.
•SCMS Collection Manager—Implementation of a collection system that receives Raw Data Records (RDRs) from one or more Cisco SCE platforms. The Collection Manager collects usage information and statistics, and stores them in a database. The Collection Manager also converts subscriber usage information and statistics into simple text-based files for further processing and collection by external systems.
For more information about the installation and operation of the Collection Manager, see the Cisco Service Control Management Suite Collection Manager User Guide.
•Service Control Application Reporter—A software component that processes data stored by the Collection Manager and provides a set of insightful reports from this data. The SCA Reporter can run as a standalone or as an integrated part of the Cisco SCA BB Console.
For more information about the installation and operation of the SCA Reporter, see the Cisco SCA BB Reporter User Guide.
Together, the Cisco SCE platform, the SCMS Collection Manager, the SCMS Subscriber Manager, and the SCA Reporter or Cisco Insight are designed to support detailed classification, analysis, reporting, and control of IP network traffic. The SCMS Collection Manager, the SCA Reporter, and the SCMS Subscriber Manager are optional components; not all deployments of the Cisco Service Control solution require them. The following sites may not require all these components:
•Sites that employ third-party collection and reporting applications
•Sites that do not require dynamic subscriber-aware processing
•Sites that use a RADIUS or DHCP sniffing option.

2 Cisco Service Control Solution Topology
This section describes the possible deployment topologies of the Cisco Service Control solution.
Note This section presents the deployment topologies for the Cisco SCE 8000 platform. For information regarding the deployment topologies for the Cisco SCE 2000 platform, see the "Cisco SCE 2000 Platform Installation" section.
Overall System Topology
Figure 2 illustrates the general topology of the Cisco Service Control solution.
•Horizontal flow—Represents traffic between subscribers and an IP network.
The SCE platform monitors traffic flow.
•Vertical flow—Represents transmission of RDRs from the Cisco SCE platform to the SCMS Collection Manager.
The SCMS Subscriber Manager provides subscriber data. This flow allows Cisco SCA BB to conduct subscriber-level analysis and control.
Figure 2 Flow of Information in SCA BB
Cisco SCE 8000 Platform Topologies
The Cisco SCE 8000 platform is an ideal solution for dual links with load sharing and asymmetrical routing and support for fail-over between two Cisco SCE platforms.
Cisco SCE 8000 is built to support wire-speed processing of full-duplex 10 GBE streams. The Cisco SCE 8000 can, therefore, be deployed in a multilink environment, in several topologies:
•Single Cisco SCE 8000 topology—Enables processing of both upstream and downstream paths of a bidirectional flow, even if these paths traverse different links.
•Dual Cisco SCE 8000 topology (cascade)—Provides high-availability and fail-over solution, and maintains the line and service in case of Cisco SCE 8000 failure.
•Multi-Gigabit Service Control Platform (MGSCP) topology—Provides scalability. The Cisco SCE 8000 platform supports the option to connect multiple SCE platforms to a Cisco 7600 Series Router to perform load balancing between the platforms.
Physical Topologies
These are the descriptions of the physical topologies that Cisco SCE 8000 supports:
•Single Cisco SCE 8000 Topologies
•Dual Cisco SCE 8000 Topology (Cascade)
•Multi-Gigabit Service Control Platform (MGSCP) Topology
Single Cisco SCE 8000 Topologies
A single Cisco SCE 8000 supports both single 10GBE link and dual 10GBE link topologies.
•Single Link: Inline Topology
•Dual Link: Inline Installation
•Single Link: Receive-Only Topology
•Dual Link: Receive-Only Topology
Single Link: Inline Topology
Typically, Cisco SCE 8000 is connected in a full-duplex 10GBE link between two devices (Router, broadband remote access server, and so on). When Cisco SCE 8000 is installed inline, it physically resides on the data link between the subscribers and the network (see Figure 3).
Figure 3 Single Link: Inline Topology
Dual Link: Inline Installation
In this topology, a Cisco SCE 8000 is connected inline in two full-duplex, 10GBE links (see Figure 4).
If load sharing exists between two links, asymmetrical routing might occur, and some of the flows may be split, that is, the upstream packets of the flow go on one link, and the downstream packets go on the other link.
When installed in this topology, Cisco SCE 8000 completely overcomes this phenomenon, and provides its normal functionality as if there is no asymmetrical routing in the two links.
Figure 4 Dual Link: Inline Installation
Single Link: Receive-Only Topology
In this topology, an optical splitter resides physically on the 10GBE link between the subscribers and the network (see Figure 5). The traffic passes through the optical splitter, which splits the traffic to Cisco SCE 8000. As a result, Cisco SCE 8000 only receives traffic and does not transmit.
Figure 5 Single Link: Receive-Only Topology
In an optical splitter topology, Cisco SCE 8000 enables only the traffic monitoring functionality.
Note When implementing receive-only topologies with a switch, the switch must support the SPAN functionality that includes separation between ingress and egress traffic and multiple SPAN ports destinations.
Dual Link: Receive-Only Topology
In this topology, a Cisco SCE 8000 is connected in receive-only mode to two full-duplex, 10 GBE links by using optical splitters (see Figure 6).
As with the dual link, inline topology, this topology completely overcomes the problem of asymmetrical routing.
Figure 6 Dual Link: Receive-Only Topology
Note When implementing receive-only topologies with a switch, the switch must support the SPAN functionality that includes separation between ingress and egress traffic and multiple SPAN ports destinations.
Dual Cisco SCE 8000 Topology (Cascade)
In this topology, two cascaded Cisco SCE 8000s are used. This topology allows a failover solution. If one Cisco SCE 8000 fails, the redundant platform preserves the functionality that Cisco SCE 8000 provides (see Figure 7).
This topology allows control and monitoring functionality, where redundancy is required and inline connection is used. The primary Cisco SCE 8000 processes the traffic of the two links, whereas the secondary Cisco SCE 8000 only bypasses the traffic of its links to the primary Cisco SCE 8000 for processing, and then bypasses the processed traffic back to the link. The two Cisco SCE 8000s also exchange keep-alive messages and subscriber state information.
If the primary Cisco SCE 8000 fails, the two Cisco SCE 8000s switch their roles, and failover is provided.
Figure 7 Two Cascaded Cisco SCE 8000 Platforms
This failover solution preserves the Cisco SCE 8000 functionality and the network link:
•Two Cisco SCE 8000s are simultaneously synchronized about the subscriber contexts. Subscriber states are constantly exchanged between them, such that if the primary Cisco SCE 8000 fails, the secondary one can take over with minimum state loss.
•When one Cisco SCE 8000 fails, depending on the type of failure, its link traffic is still bypassed to the functioning Cisco SCE 8000 and processed there, so that traffic processing continues for both the links.
•You can configure the bypass of traffic through the failed Cisco SCE 8000, and choose to always cut off the line that goes through the failed Cisco SCE 8000. In such a scenario, network redundancy protocols, such as Hot Standby Router Protocol (HSRP), are responsible for identifying the line cutoff and switching the traffic such that it goes through the functioning Cisco SCE 8000.
•You can configure Cisco SCE 8000 to use an external optical bypass device so that if it fails, the bypass device is used to provide link continuity. This configuration ensures 100 percent link continuity at the expense of providing asymmetric routing functionality.
Multi-Gigabit Service Control Platform (MGSCP) Topology
In this topology, multiple Cisco SCE 8000 platforms are connected to a Cisco 7600 Series router, which acts as a dispatcher between the platforms (see Figure 8). The router contains two EtherChannels (ECs), one for the subscriber side and one for the network side, that perform load balancing for the Cisco SCE platform traffic. Traffic enters the first router, is distributed between the Cisco SCE platforms by the subscriber-side EC, and then returns to the router so that it can be forwarded to its original destination.
Figure 8 Basic MGSCP Topology
There are a number of variables to be considered in the MGSCP topology, two of which include:
•Type of SCE Platform Redundancy
•Redundant Cisco 7600 Series Router
Type of SCE Platform Redundancy
There are two types of SCE platform redundancy:
•All Active
All the ports in the EtherChannel and all the Cisco SCE platforms are active. If a failure occurs on one of the Cisco SCE platforms, the links on the related ports in the EC go down and the EC automatically excludes them from load distribution. The load is then distributed among the active Cisco SCE platforms.
Because Cisco SCE 8000 supports two links, this configuration requires one Cisco SCE platform per two links (two EC ports).
•N+1
N Cisco SCE platforms are active and one platform is on standby. The EC ports connected to the standby Cisco SCE platform must be configured as standby ports. If one Cisco SCE platform fails, the EtherChannel ports connected to the failing SCE platform are shut and the standby EtherChannel ports, connected to the standby SCE platform are activated.
Because Cisco SCE 8000 supports two links, this configuration requires one SCE platform per two links (two EtherChannel ports), plus one extra SCE platform for standby.
Note The standby SCE platform must be connected to the two highest-numbered ports, because EC behavior automatically designates these ports as the standby ports.
Redundant Cisco 7600 Series Router
Two Cisco 7600 Series routers can be used to provide network redundancy (see Figure 9).
In this topology, one link on each Cisco SCE 8000 platform is connected to each router. Therefore, one SCE platform is required for each link.
Figure 9 MGSCP with Redundant Router
3 System Installation
This chapter describes the system installation of the Cisco Service Control solution.
Installing the Cisco SCE 8000 Platform
To install the Cisco SCE 8000 platform, complete the following steps. (For more information, see the Cisco SCE 8000 10GBE Installation and Configuration Guide or the Cisco SCE 8000 GBE Installation and Configuration Guide.)
Note For information about installing an SCE 2000 platform, see the "Installing a Cisco SCE 2000 Platform" section.
Step 1 Install the Cisco SCE platform on the rack.
Step 2 Connect the chassis ground and the power.
Step 3 Connect the CON port to a local terminal. Configure the initial setup parameters as necessary. (See the "Initial Configuration of the Cisco SCE 8000 Platform" section).
Step 4 Connect the MNG port to the local LAN.
Step 5 Cable the line ports. (See the"Cisco SCE 8000 Connectivity" section for a summary of proper cabling for various topologies).
Cisco SCE 8000 Connectivity
Table 1, Table 2, Table 3, Table 4, and Table 5 summarize Cisco SCE 8000 connectivity for the basic topologies.
Note Receive-only topologies use only Receive fibers. these can be implemented by using either an optical splitter or a switch. If a switch is used, it must support SPAN functionality that includes separation between ingress and egress traffic and multiple SPAN ports destinations.

MGSCP Topologies
In an MGSCP deployment, the exact cabling scheme depends on the number and arrangement of ports in the EtherChannel in the Cisco 7600 Series router. It is, therefore, not possible to provide exact cabling schemes.
The following general guidelines are applicable during the process of designing the cabling scheme:
•Because there are two links per Cisco SCE 8000 platform, the minimum number of platforms required is half the number of links used.
•Each link corresponds to one port on the EtherChannel on the Cisco 7600 Series router. Each EtherChannel supports a maximum of eight ports. Therefore, if all eight EtherChannel ports are configured, four Cisco SCE 8000 platforms are required.
•For N+1 redundancy, two ports (connected to the standby platform) must be configured as standby ports on both EtherChannels. Therefore, for N+1 redundancy, one router and five Cisco SCE 8000 platforms will be used to support eight links.
•If two Cisco 7600 Series routers are used (for network redundancy), one link on each Cisco SCE 8000 platform is connected to each router. This topology requires twice the number of Cisco SCE 8000 platforms, one platform for each link.
–A minimum of eight Cisco SCE 8000 platforms are required to support eight ports.
–For N+1 redundancy, nine Cisco SCE 8000 platforms are used to support eight active links.
When cabling to the EtherChannel, follow these guidelines:
•The Cisco SCE platform ports must be connected to the EtherChannel ports in the same order on both sides.
•The EtherChannel ports must be sorted in ascending order by their physical interface numbers.
•In a topology with two Cisco 7600 Series routers, the order of connection to the EtherChannel ports must be the same on both routers. For both routers to send the traffic of a given subscriber to the same Cisco SCE platform, the Cisco SCE platforms must be connected to both routers in the same order (one Cisco SCE platform connected to the first link on both routers, another Cisco SCE platform connected to the second link on both routers, and so on).
Installing the Subscriber Manager
This section describes how to install Subscriber Manager, Release 4.0.x, on a computer running Solaris or Red Hat Linux.
For more information, see the Cisco SCMS Subscriber Manager User Guide.
To install Subscriber Manager, Release 4.0.x, complete these steps:
Step 1 Use FTP to load the distribution files to the Subscriber Manager and extract them.
Step 2 Determine the system memory settings.
Set the system memory configuration requirements according to the maximum number of subscribers. See the "Installation Procedure" section in the "Installation and Upgrading" chapter of the Cisco Service Control Management Suite Subscriber Manager User Guide.
Step 3 Configure the shared memory settings.
TimesTen requires that certain changes be made in the OS kernel configuration file:
•For Solaris, modify the /etc/system file.
•For Linux, modify the /etc/sysctl.conf file.
These changes increase the shared memory and semaphore resources on the machine from their defaults. See the "Installation Procedure" section in the "Installation and Upgrading" chapter of the Cisco Service Control Management Suite Subscriber Manager User Guide.
Step 4 (Optional) Edit the install-def.cfg file.
Note We recommend that you edit the install-def.cfg file if you do not want the default parameter values to be used.
The install-def.cfg file contains several parameters that can be configured before you install the Subscriber Manager. The installation routine copies these parameters to the relevant Subscriber Manager configuration file. By default, all the parameters are commented and the default values are used.
Table 6 lists the parameters of the install-def.cfg file.
Table 6 Parameters of the install-def.cfg File

database_temp_size |
Database definitions |
Defines the TempSize, in megabytes, allocated for the database. |
The TempSize parameter in the /var/TimesTen/sys.odbc.ini file. |
Step 5 Execute the install-sm.sh script.
Note You can customize the install-sm.sh script.
Note If the /etc/motd file exists, it is not possible to run the script. Move or remove the /etc/motd file before you run the install-sm.sh script.
From your workstation shell prompt, move to the directory to which the distribution file was extracted and run the install-sm.sh script. See the "Installation Procedure" section of the "Installation and Upgrading" chapter of Cisco Service Control Management Suite Subscriber Manager User Guide.
Step 6 Set the password for the pcube user.
After the installation script runs successfully, set the password for the pcube user by running the # passwd pcube command.
Note We recommend that you note down this password for future use.
Step 7 Reboot the computer. This step is mandatory to complete the installation.
Step 8 Add a user for PRPC authentication.
It is necessary to add a user for PRPC authentication because Cisco SCA BB requires a username and password when connecting to the Subscriber Manager.
To add a user for PRPC authentication, use the p3rpc command-line utility. For example:
>p3rpc --set-user --username=pcube --password=pcube-password
Installing the Collection Manager
This section describes how to install the Collection Manager, either with the bundled Sybase database or unbundled, on a computer running Solaris or Red Hat Linux:
•Ports Used by the Collection Manager Software
•Installing the Sybase Database
•Installing Collection Manager Software
For more information, see the Cisco Service Control Management Suite Collection Manager User Guide.
Ports Used by the Collection Manager Software
Table 7 describes the TCP/UDP ports on which the Collection Manager software and associated components (such as the Sybase database) listen. This table helps the network administrator understand the behavior of the software and its adherence to the security policy.

The ports that are listed are those ports on which the device listens constantly. Allow access on these port numbers; otherwise, certain operations may fail.
Some operations (such as file transfer) cause a device to open ports, other than those listed, temporarily; however, these ports close automatically after the operation ends.
Installing the Sybase Database
If you do not want to install Sybase (for example, when working in the unbundled mode), perform the task described in the "Installing Collection Manager Software" section.
Keep the following points in mind when using the Sybase database:
•Installing the Sybase database can take up to three hours.
•When using the bundled Sybase database, the server on which you install the Collection Manager can have a maximum of four CPU cores.
•The maximum database size supported by the bundled Sybase database is 50 GB. For database support larger than 50 GB, use an external database.
The installsyb.sh script installs the Sybase database. For information about the actions performed by the script, see the Cisco Service Control Management Suite Collection Manager User Guide.
Step 1 Log in as the root user and make the distribution kit contents available on your system or local network.
Step 2 In the distribution kit root, change directory to sybase.
Step 3 Run the installsyb.sh script as follows:
installsyb.sh --sybhome=SYBHOME {--datadir=DATADIR}
•SYBHOME is the home directory of the Sybase user. The Sybase home directory for Linux should have 2 GB free space and for Solaris 6 GB free space.
•Select the data location option by specifying:
–Specify --datadir=DATADIR. Here, DATADIR is the directory in which all Sybase data is stored.
Use a location in a partition where at least 30 GB free space is available.
•If you specify a DATADIR, all the Sybase data is stored as normal files in that directory, with default sizes of 20 GB for data, 6 GB for logs, and 2 GB for Sybase temporary storage. The ownership of the directory is changed to the Sybase user during installation.
Step 4 After the script completes, set a password for the sybase user. Use the passwd command as follows:
Installing Collection Manager Software
Use the install-cm.sh script to install the Collection Manager server.
install-cm.sh Options
The usage message for the install-cm.sh script is:
Usage: install-cm.sh [-h] (-d CMDIR | -o)
Options: -d CMDIR select directory for ~scmscm
(must not exist and must be on 8 GB free partition)
-o upgrade the existing installation
while preserving the current configuration
-h print this help and exit
The description of the options is as follows:
Used to designate the directory of the newly created
scmscm user's home. Should be the name of a
non-existing directory, whose parent resides on a
partition where at least 8 GB is free.
As an alternate to this option, you can specify -o :
Use this option when you wish to upgrade the existing
installation while preserving the current configuration.
For information about the actions performed by the install-cm.sh script, see the Cisco Service Control Management Suite Collection Manager User Guide.
Install the Collection Manager server by performing the following procedure:
Step 1 Change directory to install-scripts under the distribution kit root.
Step 2 Run the install-cm.sh script:
# install-cm.sh -d <CM home dir>
After running the script, a user-driven configuration manager presents the user with options for the basic configuration of the Collection Manager.
Step 3 Choose one of the options provided by the configuration manager:
Please select one of the following options:
3 - Install CM:RDR and CM:NetFlow
•Choose option 1 if the Collection Manager is being configured to operate with Cisco SCE.
•Choose option 2 if the Collection Manager is being configured to operate with the Cisco ASR 1000 Series Aggregation Services Routers.
•Choose option 3 if the Collection Manager is being configured to operate with both Cisco SCE and the Cisco ASR 1000 Series Aggregation Services Routers.
•Choose option 4 is chosen to exit the Collection Manager installation.
Step 4 Choose whether to enable or not enable the real-time aggregating (RAG) adapter. For more information on the RAG adapter, see the Cisco Service Control Management Suite Collection Manager User Guide.
Do you want to enable the RAG Adapter? (yes/no):
Step 5 You can choose to set up the Collection Manager database at the time of installation or configure it at a later time.
Would you like to configure the database?: yes
Step 6 If you choose to configure the database:
a. Select the number corresponding to the relational database management system of the connecting database:
For more information, see the "Configuring Databases" section in the "Managing the Collection Manager" chapter of the Cisco Service Control Management Suite Collection Manager User Guide.
b. Enter the following server information or press Enter to leave at the default shown.
Enter DB server host (default localhost):
Enter DB server listening port (default port no) :
Enter DB server instance id (default schema) :
Enter DB schema user name (default user_id) :
Enter DB schema user password (default password) :
You will see the following text:
Note A failed connection results in the user being prompted to re-enter the DB information.
Note After the user configures the requested database options, the dbinfo.vm file updates for the RDR database configuration details, the Cisco IOS Flexible NetFlow database configuration details, or the configuration details of both the RDR database and the Cisco IOS Flexible NetFlow database.
Note We recommend that you set up separate databases for each platform.
Step 7 After the script completes running, set a password for the scmscm user:
We recommend that you maintain a record of the password.
Step 8 (Optional) To configure the Collection Manager to use an external database, use the ~scmscm/scripts/dbconf.sh -- rdr script.
This is a list of supported external databases:
•Oracle—Releases 9.2, 10g, and 11g
•MySQL—Releases 4.1 and later
•Sybase—Version 12.5.1 and later
Step 9 Start the database.
If you are using an external database, start it according to the instructions supplied by the database vendor.
If you are using the Sybase database:
a. As the root user, run the sybase start command:
# ~scmscm/setup/sybase start
b. Wait for several minutes and run the alive.sh script:
# ~scmscm/setup/alive.sh
Make sure that the output does not contain the phrase Sybase not functioning.
Step 10 Configure the adapters to use and the categorizer.
For details, see the "Configuring the Collection Manager" section of the Cisco Service Control Management Suite Collection Manager User Guide.
Step 11 Set the Collection Manager time zone by using the jselect-sce-tz.sh script. For example, if the Cisco SCE device is located in GMT+2, run this command as the scmscm user:
$ ~scmscm/cm/bin/jselect-sce-tz.sh --rdr --offset=120
Step 12 Activate the periodic delete procedures for the database tables by running the create_periodic_del_procs.sh script as the scmscm user:
~scmscm/db_maint/create_periodic_del_procs.sh --rdr
For details, see the "Managing the Periodic Deletion of Old Records" section of the Cisco Service Control Management Suite Collection Manager User Guide.
Step 13 Activate the automatic invocation of the periodic delete procedures:
$~scmscm/scripts/dbperiodic.sh --rdr --load
This loads the default data retention settings defined in ~scmscm/db_maint/dbperiodic.conf.
Step 14 Start the Collection Manager by running this command:
~scmscm/cm/bin/cm start
Step 15 Add a user for PRPC authentication. It is necessary to add a user for PRPC authentication because Cisco SCA BB requires a username and password when connecting to the CM.
To add a user for PRPC authentication, use the p3rpc command-line utility:
~scmscm/cm/bin/p3rpc --set-user --username=scmscm --password=scmscm-password

Note The initial setup process is flexible, and you may find that you prefer to do things slightly differently. The steps mentioned above can be considered as a suggested approach, rather than a mandatory approach.
Initial Configuration of the Cisco SCE 8000 Platform
Note The initial setup of the Cisco SCE 2000 platform should be performed by using the setup wizard. See the "Initial System Configuration" section for more information about the Cisco SCE 2000 setup wizard.
There are several basic global parameters that must be correctly configured for the Cisco SCE platform to communicate properly with the outside world. The following is a brief summary of the initial setup parameters and commands. For more information, see the Cisco SCE8000 10GBE Software Configuration Guide or the Cisco SCE8000 GBE Software Configuration Guide.
•IP address and subnet mask of the Cisco SCE 8000 platform. This IP address is used by the GBE management interface.
•IP address of the default gateway.
•Hostname—The hostname is used to identify the Cisco SCE platform. It appears as part of the CLI prompt and is also returned as the value of the MIB-II object sysName.
–The maximum length is 20 characters.
–The default hostname is SCE8000.
•Passwords for user, admin, and root-level access. These are authorization-level passwords, not individual passwords. These passwords may be encrypted.
These passwords must meet the following criteria:
–Minimum length—Four characters
–Maximum length—100 characters
–Begin with an alpha character
–Must contain only printable characters
•The default password for all levels is cisco.
•System clock—Current date and time. The clock and the calendar must always be synchronized.
•Time zone—The name or ID of the time zone along with the number of hours offset from Coordinated Universal Time (UTC).
•Domain name server—The default domain name used to complete unqualified host names, as well as up to three domain name servers, that are used for DNS lookup. You must also enable DNS lookup.
•RDR formatter destination—The Cisco SCE platform generates RDRs and sends them to the specified destinations (external collection systems) via the RDR formatter. You can configure up to eight RDR formatter destinations. Specify the IP address and port number for each destination.
Table 8 lists the commands both for displaying the currently configured values and for configuring these parameters. It also lists the command mode for each configuration command. All the show commands are executed in the user EXEC command mode.

–The wizard cannot connect to any of the SCE devices that you listed in Step 4.
–You defined a Collection Manager in Step 8, but the wizard cannot connect to it.
–You defined a database in Step 10, but the wizard cannot connect to it.
If you defined a Collection Manager in Step 8, the SCE devices are configured so that the only category 1 RDR destination is the CM.
A new service configuration named Usage Analysis is created, and opens in the Service Configuration Editor (see Figure 32).
Figure 32 Service Configuration Editor
The service configuration has these characteristics:
•They are in Report Only mode.
•The maximum Transaction RDR rate is set as the default value (250) divided by the number of SCE devices. (To configure the Transaction RDR see How to Manage Transaction RDRs in the Cisco Service Control Application for Broadband User Guide. The content and structure of the Transaction RDR is listed in "Transaction RDR" in the "Raw Data Records: Formats and Field Contents" chapter of Cisco Service Control Application for Broadband Reference Guide.)
The service configuration is applied to the SCE devices.
If you defined a database in Step 10:
a. The SCA BB Reporter tool is connected to the selected database.
b. The first SCE platform entered in Step 4 is selected as the source of service configuration data.
c. The Next button is enabled.
Step 16 If you did not define a database in Step 10, click Close.
The Usage Analysis wizard closes.
Step 17 Click Next.
The Create common reports window opens (see Figure 33).

Note Report instances are created for four predefined report types:
· Global Bandwidth per Service
· Global Active Subscribers per Service
· Top P2P Protocols
· Global Hourly Call Minutes per Service (VoIP)
Step 19 Click Close.
The wizard closes.
The Reporter tool opens in the Console.
Report instances of each of the four report types open in the Report View of the Reporter tool.
Configuring the Subscriber Manager
After installing the SCMS Subscriber Manager, you can configure the Subscriber Manager to your specific needs. In particular, address these parameters:
•topology—Cluster or standalone
•introduction_mode—Pull or push
•support_ip_ranges—Whether IP ranges should be used in the installed setup
To configure the Subscriber Manager, edit the p3sm.cfg configuration file by using any standard text editor. The configuration file is described in detail in the Configuration and Management module and in the Configuration File Options module of Cisco Service Control Management Suite Subscriber Manager User Guide.
After you finish editing the p3sm.cfg configuration file, use the p3sm utility to update the Subscriber Manager with the new settings:
At your workstation shell prompt, run the p3sm command.
This p3sm command loads the configuration file and updates the Subscriber Manager configuration accordingly:
5 Cisco SCE 2000 Platform Installation
This chapter summarizes the topologies and installation of the Cisco SCE 2000 platform. In general, these installations and topologies are similar to that of Cisco SCE 8000 platform, but there are some differences.
Cisco SCE 2000 Platform Topologies
The Cisco SCE 2000 can be deployed in the same topologies as the Cisco SCE 8000 platform. Figure 34, Figure 35, Figure 36, Figure 37, and Figure 38 illustrate the Cisco SCE 2000 topologies.
Figure 34 Single SCE Platform Single Link: In-line Topology
Figure 35 Single SCE Platform Dual Link In-line Topology
Figure 36 Single SCE Platform Single Link: Receive-Only Topology
Figure 37 SCE Platform Dual Link: Receive-Only Topology
Figure 38 Two SCE Platforms: Dual Link In-line Topology
Installing a Cisco SCE 2000 Platform
To install the SCE platform, complete the following steps. (For more information, see the Cisco SCE 2000 Installation and Configuration Guide.)
Step 1 Install the SCE platform in the rack.
Step 2 Connect the chassis ground and the power.
Step 3 Connect the CON port to a local terminal and perform the initial configuration by using the setup wizard.
a. Press Enter several times until the Cisco logo appears on the local terminal and the setup configuration dialog is entered:
--- System Configuration Dialog ---
At any point you may enter a question mark `?' followed by `Enter' for help.
Use ctrl-C to abort configuration dialog at any prompt.
Use ctrl-Z to jump to the end of the configuration dialog at any prompt.
Default settings are in square brackets `[]'.
Would you like to continue with the System Configuration Dialog? [yes/no]: y
b. Type y and press Enter.
The system configuration dialog begins. See the "Initial System Configuration" section for information about the setup wizard.
Step 4 Connect the MNG port to the local LAN.
If you are using both MNG ports for redundancy, connect them to the LAN via a switch.
Step 5 Cable the line ports. (See the "SCE 2000 Connectivity" section for a summary of proper cabling for various topologies.)
Initial System Configuration
Upon initial connection to the local terminal, the system configuration wizard automatically runs to guide the user through the entire setup process. The wizard prompts for all necessary parameters, displaying default values, where applicable. You may accept the default values or define other values.
Except for the time settings, which take effect immediately when entered, the new configuration is applied and saved only at the end of the dialog when approved by the user. Therefore, if the setup dialog is aborted, no change takes place in the configuration, other than time settings (if entered).
When the dialog is complete, you may review the new configuration before applying it. The system displays the configuration, including parameters that were not changed. The system also displays any errors that are detected in the configuration. When the configuration is satisfactory, you may apply and save the new configuration.
Table 9 lists all the parameters included in the initial configuration. We recommend that you obtain values for any parameters that you configure at this time before beginning the setup.
Note For further information about any configuration step or specific parameter, see the relevant section of Cisco SCE 2000 and SCE 1000 Software Configuration Guide.

MGSCP Topologies
In an MGSCP deployment, the exact cabling scheme depends on the number and arrangement of ports in the EtherChannel in the Cisco 7600 Series router. It is, therefore, not possible to give exact cabling schemes. See the following general guidelines when designing the cabling scheme:
•Because there are two links per Cisco SCE 2000 platform, the minimum number of platforms required is half the number of links used.
•Each link corresponds to one port on the EtherChannel on the Cisco 7600 Series router. Each EtherChannel supports a maximum of eight ports. Therefore, if all eight EtherChannel ports are configured, four Cisco SCE 2000 platforms are required.
•For N+1 redundancy, two ports (connected to the standby platform) must be configured as standby ports on both ECs.
–For N+1 redundancy, one router and five Cisco SCE 2000 platforms would be used to support eight links.
•If two Cisco 7600 Series routers are used (for network redundancy), one link on each Cisco SCE 2000 platform is connected to each router. This topology requires twice the number of Cisco SCE 2000 platforms, one platform for each link.
–Minimum of eight Cisco SCE 2000 platforms are required to support eight ports.
–For N+1 redundancy, nine Cisco SCE 2000 platforms would be used to support eight active links.
When cabling to the EC, follow these guidelines:
•Cisco SCE platform ports must be connected to the EtherChannel ports in the same order on both sides.
•EtherChannel ports must be sorted in an ascending order by their physical interface numbers.
•In a topology with two Cisco 7600 Series routers, the order of connection to the EtherChannel ports must be the same on both routers. For both routers to send the traffic of a given subscriber to the same SCE platform, the SCE platforms must be connected to both routers in the same order (one SCE platform connected to the first link on both routers, another SCE platform connected to the second link on both routers, and so on).
6 System Requirements and Prerequisites
This chapter summarizes the system requirements and prerequisites of the Cisco SCE 2000 platform.
Overall System Requirements
•The SCE platform—Local console or management workstation connected to LAN.
•Cisco SCA BB—Workstation running Windows 2000, Windows XP, Windows Vista, or Windows 7.
•SCMS Subscriber Manager—Either of these:
–Solaris—Sun SPARC machine (64 bit) running 64-bit versions of Solaris 9 or Solaris 10 with a 64-bit version of the Java Virtual Machine.
–Linux—Intel-based machine with a 32-bit or 64-bit CPU running a 32-bit version of Linux with a 32-bit version of the Java Virtual Machine.
The actual number of computers required depends on the number of subscribers in the system.
•SCMS Collection Manager—either of these:
–Solaris—Sun SPARC machine running Solaris 8 or Solaris 9.

These sections describe the Collection Manager system requirements:
•Checking a System's Prerequisites
•Solaris Requirements
•Red Hat Linux Requirements
Checking a System's Prerequisites
The CM distribution contains a script, check_prerequisites.sh, located in the install_scripts directory:
check_prerequisites.sh [--sybhome=SYBHOME] [--cmhome=CMHOME] [--datadir=DATADIR]
The script helps to determine if a system meets the requirements for installing a CM or the bundled Sybase database. It also checks the overall readiness of the system for a Collection Manager or Sybase installation. The main prerequisites that are checked are:
•CPU speed
•Amount of RAM
•OS version (Solaris 9 or 10, Red Hat Enterprise Linux 4 or 5)
•Additional required and optional packages
•Python installed and executable in path
•Free space for CM and Sybase homes
•Names for all the network interface cards (NICs)
•Sybase kernel parameters
•Locale and time zone formats
Table 18 describes the options available in the check_prerequisites.sh script.

•(For installations with bundled Sybase) At least 3 GB free space on one partition for the Sybase home directory.
•(For installations with bundled Sybase) Free space on one partition to hold the desired size of the Sybase data and logs (the sizes are configurable at installation time).
•(For installations with bundled Sybase where the legacy [pre-3.0] Cisco Service Control Reporter is to be used.) An FTP server should be listening on port 21 so that the Cisco SCA Reporter can authenticate against it.
•(For installations with bundled Sybase) Before installation, verify that all the IP addresses that are configured for the machine NICs have hostnames associated with them in /etc/hosts or in another active naming service. (This is a limitation of Sybase Adaptive Server Enterprise.)
•(For installations with bundled Sybase) Use the set_shmmax.sh script (located in install-scripts/) to configure the kernel memory.
•Additionally, at startup, load the IPC module by adding these lines in the /etc/system file:
•If you are using database periodic delete, the scmscm user should be able to schedule and run cron jobs.
Setting the Locale and Time Zone
For correct CM and Sybase operation, U.S. English locale must be used. To set the locale, add this line in the /etc/TIMEZONE configuration file (changes to this file require a restart to take effect):
Solaris also requires this locale to be installed. Verify that the locale is installed by checking whether the directory /usr/lib/locale/en_US exists. If the directory does not exist, install the locale files from the Solaris CDs.
