Save your configuration as described in the Saving Your Configuration chapter.
*IMPORTANT: Commands used in the configuration examples in this section provide base functionality to the extent that the most common or likely commands and/or keyword options are presented. In many cases, other optional commands and/or keyword options are available. Refer to the Command Line Interface Reference for complete information regarding all commands.
Creating the ECS Administrative User Account
At least one administrative user account that has ECS functionality privileges must be configured on the system. This is the account that is used to log on and execute ECS-related commands. For security purposes, it is recommended that these user accounts be created along with general system functionality administration.
Use the following configuration example to create the ECS Administrative user account:
configure
context local
administrator <user_name> password <password> ecs
end
Notes:
l
Aside from having ECS capabilities, an ECS Administrator account also has the same capabilities and privileges as any other system-level administrator account.
l
You can also create system ECS user account for a config-administrator, operator, or inspector. ECS accounts have all the same system level privileges of normal system accounts except that they have full ECS command execution capability. For example, an ECS has rights to execute every command that a regular administrator can in addition to all of the ECS commands.
l
Note that only Administrator and Config-administrator-level users can provision ECS functionality. Refer to the Configuring System Settings chapter of the System Administration and Configuration Guide for additional information on administrative user privileges.
Installing the ECS License
To configure and enable ECS functionality on your system you must obtain and install the [600-00-7526] Enhanced Charging Bundle 1 1k Sessions license.
To configure and enable Diameter and DCCA functionality with ECS on your system, you must obtain and install the [600-00-7574] Enhanced Charging Bundle 2 1k Sessions license.
For information on installing licenses, see the Managing License Keys section of the Software Management Operations chapter in the Administration and Configuration Guide.
Enabling Active Charging Service
Active Charging must be enabled before configuring charging services.
Use the following configuration example to enable Active Charging Service:
configure
require active-charging
context local
interface <interface_name>
ip address <ip_address/mask>
exit
server ftpd
end
Notes:
l
If you are using the Category-based Content Filtering application, refer to the Content Filtering Services Administration Guide for specific configuration procedures.
Configuring the Enhanced Charging Service
A charging service has analyzers that define which packets to examine and ruledefs (ruledefs) that define what packet contents to take action on and what action to take when the ruledef is true. Charging services are configured at the global configuration level and are available to perform packet inspection on sessions in all contexts.
To configure the Enhanced Charging Service:

Save your configuration as described in the Saving Your Configuration chapter.
*IMPORTANT: Commands used in the configuration examples in this section provide base functionality to the extent that the most common or likely commands and/or keyword options are presented. In many cases, other optional commands and/or keyword options are available. Refer to the Command Line Interface Reference for complete information regarding all commands.
Creating the Active Charging Service
Use the following configuration example to create an Active Charging Service:
configure
active-charging service <service_name> [ -noconfirm ]
end
Configuring Rule Definitions
A ruledef can be a charging or routing, or a post-processing rule. If the same ruledef is required to be a charging rule in one rulebase and a post-processing rule in another one, then two separate identical ruledefs will have to be defined.
Configuring Charging Rule Definitions
Use the following configuration example to create and configure a charging ruledef:
configure
active-charging service <service_name>
ruledef <ruledef_name>
<protocol> <expression> <operator> <condition>
rule-application charging
end
Notes:
l
For information on all the protocol types, expressions, operators, and conditions supported, refer to the Ruledef Configuration Mode Commands chapter of the Command Line Interface Reference.
Verifying your Configuration
To verify your configuration, in the Exec Mode, enter the following command:
show active-charging ruledef charging
Configuring Routing Rule Definitions
Use the following configuration example to create and configure a routing ruledef:
configure
active-charging service <service_name>
ruledef <ruledef_name>
<protocol> <expression> <operator> <condition>
rule-application routing
end
Notes:
l
l
For information on all the protocol types, expressions, operators, and conditions supported, refer to the Ruledef Configuration Mode Commands chapter of the Command Line Interface Reference.
l
Verifying your Configuration
To verify your configuration, in the Exec Mode, enter the following command:
show active-charging ruledef routing
Configuring Post-processing Rule Definitions
Use the following configuration example to create and configure a post-processing ruledef:
configure
active-charging service <service_name>
ruledef <ruledef_name>
<protocol> <expression> <operator> <condition>
rule-application post-processing
end
Notes:
l
l
For information on all the protocol types, expressions, operators, and conditions supported, refer to the Ruledef Configuration Mode Commands chapter of the Command Line Interface Reference.
Verifying your Configuration
To verify your configuration, in the Exec Mode, enter the following command:
show active-charging ruledef post-processing
Configuring Group of Ruledefs
A group-of-ruledefs enables grouping rules into categories, so that charging systems can base the charging policy on the category.
Use the following configuration example to create and configure a group-of-ruledefs:
configure
active-charging service <service_name>
group-of-ruledefs <group_name> [ -noconfirm ]
add-ruledef priority <priority> ruledef <ruledef_name>
group-of-ruledefs-application { charging | post-processing }
end
Notes:
l
Verifying your Configuration
To verify your configuration, in the Exec Mode, enter the following command:
show active-charging group-of-ruledefs all
Configuring Charging Actions
Charging actions are used with rulebases and must be created before a rulebase is configured.
Use the following configuration example to create a charging action:
configure
active-charging service <service_name>
charging-action <charging_action_name> [ -noconfirm ]
content-id <content_id>
retransmissions-counted
billing-action [ edr <edr_format> [ wait-until-flow-ends ] | egcdr | exclude-from-udrs | radius ] +
end
Verifying your Configuration
To verify your configuration, in the Exec Mode, enter the following command:
show active-charging charging-action all
Configuring IP Readdressing
Readdressing of packets based on the destination IP address of the packets enables redirecting unknown gateway traffic to known/trusted gateways. This is implemented by configuring the re-address server in the charging action.
To configure the IP Readdressing feature, use the following configuration example:
configure
active-charging service <service_name>
charging-action <charging_action_name>
flow action readdress { server <ip_address> [ port <port_number> ] | port <port_number> }
end
Configuring Next Hop Address
To configure the Next Hop Address configuration feature, use the following configuration example:
configure
active-charging service <service_name>
charging-action <charging_action_name>
nexthop-forwarding-address <ip_address>
end
Configuring Rulebases
A rulebase specifies which protocol analyzers to run and which packets are analyzed. Multiple rulebases may be defined for the Active Charging Service. A rulebase is basically a subscriber’s profile in a charging service.
Use the following configuration example to define a rulebase:
configure
active-charging service <service_name>
rulebase <rulebase_name> [ -noconfirm ]
flow end-condition { { content-filtering | normal-end-signaling | timeout + } | { { hagr | handoff | session-end } [ flow-overflow ] + } [ url-blacklisting ] } edr <edr_format_name>
billing-records udr udr-format <udr_format_name>
action priority <action_priority> { [ dynamic-only | static-and-dynamic | timedef <timedef_name> ] { group-of-ruledefs <ruledefs_group_name> | ruledef <ruledef_name> } charging-action <charging_action_name> [ monitoring-key <monitoring_key> ] [ description <description> ] }
route priority <route_priority> ruledef <ruledef_name> analyzer <analyzer> [ description <description> ]
rtp dynamic-flow-detection
udr threshold interval <interval>
cca radius charging context <context> group <group_name>
cca radius accounting interval <interval>
end
Notes:
l
When R7 Gx is enabled, “static-and-dynamic” rules behave exactly like “dynamic-only” rules. I.e. they must be activated explicitly by the PCRF. When Gx is not enabled, “static-and-dynamic” rules behave exactly like static rules.
Verifying your Configuration
To verify your configuration, in the Exec Mode, enter the following command:
show active-charging rulebase all
Setting EDR Formats
ECS generates postpaid charging data files which can be retrieved from the system periodically and used as input to a billing mediation system for postprocessing.
EDRs are generated according to action statements in rule commands.
Up to 32 different EDR schema types may be specified, each composed of up to 32 fields or analyzer parameter names. The records are written at the time of each rule event in a comma-separated (CSV) format.
*IMPORTANT: If you have configured RADIUS Prepaid Billing, configuring charging records is optional.
Use the following configuration example to set the EDR formats:
configure
active-charging service <service_name>
edr-format <edr_format_name> [ -noconfirm ]
attribute <attribute> { [ format { MM/DD/YY-HH:MM:SS | MM/DD/YYYY-HH:MM:SS | YYYY/MM/DD-HH:MM:SS | YYYYMMDDHHMMSS | seconds } ] [ localtime ] | [ { ip | tcp } { bytes | pkts } { downlink | uplink } ] priority <priority> }
rule-variable <protocol> <rule> priority <priority>
event-label <event-label> priority <priority>
end
*IMPORTANT: For information on EDR format configuration and rule variables, refer to the EDR Format Configuration Mode Commands chapter of the Command Line Interface Reference.
Verifying your Configuration
To verify your configuration, in the Exec Mode, enter the following command:
show active-charging edr-format all
Setting UDR Formats
ECS generates postpaid charging data files which can be retrieved from the system periodically and used as input to a billing mediation system for postprocessing.
UDRs are generated according to action statements in rule commands. Up to 32 different UDR schema types may be specified, each composed of up to 32 fields or analyzer parameter names. The records are written thresholds in a comma-separated (CSV) format.
*IMPORTANT: If you have configured RADIUS Prepaid Billing, configuring charging records is optional.
Use the following configuration example to set the UDR format:
configure
active-charging service <service_name>
udr-format <udr_format_name> [ -noconfirm ]
attribute <attribute> { [ format { MM/DD/YY-HH:MM:SS | MM/DD/YYYY-HH:MM:SS | YYYY/MM/DD-HH:MM:SS | YYYYMMDDHHMMSS | seconds } ] [ localtime ] | [ { bytes | pkts } { downlink | uplink } ] ] priority <priority> }
end
*IMPORTANT: For information on UDR format configuration and rule variables, refer to the UDR Format Configuration Mode Commands chapter of the Command Line Interface Reference.
Verifying your Configuration
To verify your configuration, in the Exec Mode, enter the following command:
show active-charging udr-format all
Enabling Charging Record Retrieval
To retrieve charging records you must configure the context that stores the charging records to accept SFTP connections.
Use the following configuration example to enable SFTP:
configure
context local
administrator <user_name> [ encrypted ] password <password>
config-administrator <user_name> [ encrypted ] password <password>
exit
context <context_name>
ssh generate key
server sshd
subsystem sftp
end
Notes:
l
You must specify the sftp keyword to enable the new account to SFTP into the context to retrieve record files.

apn <apn_name>
dcca peer-select peer <host_name> [ [ realm <realm_name> ] [ secondary-peer <host_name> [ realm <realm_name> ] ] ]
end
Configuring RADIUS Prepaid Credit Control Application
RADIUS prepaid billing operates on a per content-type basis. Individual content-types are marked for prepaid treatment. When a traffic analysis rule marked with prepaid content-types matches, it triggers prepaid charge management.
*IMPORTANT: The RADIUS Prepaid feature of ECS has no connection to the system-level Prepaid Billing Support or the 3GPP2 Prepaid features that are enabled under different licenses.
Use the following configuration example to configure RADIUS Prepaid Charging with Enhanced Charging feature.
*IMPORTANT: It is assumed that you have already fully configured the AAA parameters as described in the AAA Interface Administration and Reference, and Credit Control Application as described in Configuring Prepaid Credit Control Application (CCA) section for RADIUS mode.
configure
active-charging service <service_name>
credit-control [ group <group_name> ]
mode radius
exit
rulebase <rulebase_name>
cca radius charging context <vpn_context> [ group <group_name> ]
end

User traffic is directed through the ECS service inspection engine by using Access Control List (ACL) mechanism to selectively steer subscriber traffic.
To configure redirection of subscriber traffic to ECS:
1
2
3
4
5
Save your configuration as described in the Saving Your Configuration chapter.
*IMPORTANT: Commands used in the configuration examples in this section provide base functionality to the extent that the most common or likely commands and/or keyword options are presented. In many cases, other optional commands and/or keyword options are available. Refer to the Command Line Interface Reference for complete information regarding all commands.
Creating an ECS ACL
Use the following configuration example to create an ACL to use in steering subscriber traffic through ECS:
configure
context <context_name>
ip access-list <access_list_name>
redirect css service <service_name> <keywords> <options>
end
Notes:
l
<service_name> must be the ACS service name; no CSS service needs to be configured.
Applying an ACL to an Individual Subscriber
IP ACLs are applied to subscribers via attributes in their profile. The subscriber profile could be configured locally on the system or remotely on a RADIUS server.
To apply an ACL to a RADIUS-based subscriber, use the Filter-Id attribute. For more information on this attribute, refer to the AAA Interface Administration and Reference.
Use the following configuration example to apply an ACL to an individual subscriber:
configure
context <context_name>
subscriber name <subscriber_name>
ip access-group <acl_name> [ in | out ]
end
Verifying your Configuration
To verify your configuration, in the Exec Mode, enter the following commands:
context <context_name>
show subscribers configuration username <subscriber_name>
Applying an ACL to the Subscriber Named default
Use the following configuration example to apply an ACL to the default subscriber:
configure
context <context_name>
subscriber default
ip access-group <acl_name> [ in | out ]
end
Verifying your Configuration
To verify your configuration, in the Exec Mode, enter the following commands:
context <context_name>
show subscribers configuration username default
Applying the ACL to an APN
*IMPORTANT: This information is only applicable to GGSN networks.
Use the following configuration example to apply an ACL to an APN:
configure
context <context_name>
apn <apn_name>
ip access-group <acl_name> [ in | out ]
end
Verifying your Configuration
To verify your configuration, in the Exec Mode, enter the following commands:
context <context_name>
show apn name <apn_name>
Configuring GTPP Accounting
*IMPORTANT: This section assumes that you have already fully configured a GGSN service.
This section describes how to configure GTPP accounting which generates G-CDRs for ECS. Generated G-CDRs are sent to a configured Charging Gateway Function (CGF). ECS G-CDRs are sent in ASN.1 format and are encoded as described in 3GPP TS 32.015 V3.9.0 (2002–03) and 3GPP TS 29.060 V6.7.0 (2004–12).
The GGSN service should be configured in the source context.
*IMPORTANT: If you have configured RADIUS accounting you do not need to configure GTPP accounting.
Use the following configuration example to configure GTPP accounting:
configure
gtpp single-source
context <context_name>
apn <apn_name>
accounting-mode none
exit
gtpp charging-agent address <ip_address>
gtpp server <ip_address>
end
Notes:
l
The gtpp single-source command must be entered before any other configuration commands. If you add it to an existing configuration, make sure that it is the first command implemented after cards and ports are configured. This ensures that this command is implemented before any AAA Manager or Session Manager processes are started.
l
The GGSN has a concept of an accounting context. By default the accounting context is the context in which the GGSN service is configured. Make sure that you configure the GTPP charging agent and the GTPP accounting servers.
Save your configuration as described in the Saving Your Configuration chapter.
Configuring EDR/UDR Parameters
This section provides an example configuration to configure EDR/UDR file transfer and file properties parameters, including configuring hard disk support on SMC card on ST40 platform, transfer modes, transfer interval, etc.
To configure EDR/UDR file parameters:
configure
context <context_name>

Notes:
l
The cdr command keywords can be configured either in the EDR or the UDR Configuration Mode. Configuring in one mode prevents the configurations from being applied in the other mode.
l
The use-harddisk keyword is only available on the ST40 platform.
l
For the storage-limit <limit> keyword, on the ST16 platform, the total storage limit is 256 MB (268435456 bytes). And, on ST40 platform, the total storage limit is 512 MB (536870912 bytes). This limit is for both UDR and EDR files combined.
Verifying your Configurations
To view EDR-UDR file statistics, in the Exec Mode, enter the following command:
show active-charging edr-udr-file statistics
Pushing EDR/UDR Files Manually
Use the following command to manually push EDR/UDR files to the configured L-ESS:
cdr-push { all | local-filename <file_name> }
Notes:
l
l
The cdr-push command is available in the Exec Mode.
l
<file_name> must be absolute path of the local file to push.
Retrieving EDR and UDR Files
To retrieve UDR or EDR files you must SFTP into the context that was configured for EDR or UDR file generation with the FTP enabled account that you configured in the Enabling Charging Record Retrieval section.
The following commands use SFTP to log on to a context named ECP as a user named ecpadmin, through an interface configured in the ECS context that has the IP address 192.168.1.10 and retrieve all EDR or UDR files from the default locations:
sftp -oUser=ecpadmin@ECP 192.168.1.10:/records/edr/*
sftp -oUser=ecpadmin@ECP 192.168.1.10:/records/udr/*
Configuring x-header Insertion Feature
*IMPORTANT: This is a customer-specific feature. Please contact your sales representative for more information.
This section describes how to configure the x-header Insertion feature.
To configure the x-header Insertion feature:

6
Save your configuration as described in the Saving Your Configuration chapter.
Creating the x-header Format
Use the following configuration example to create an x-header format:
configure
active-charging service <acs_service>
xheader-format <xheader_format_name> [ -noconfirm ]
end
Configuring the x-header Format
Use the following configuration example to configure an x-header format:
configure
active-charging service <acs_service>
xheader-format <xheader_format_name> [ -noconfirm ]
insert <xheader_field_name> { string-constant <xheader_field_value> | variable { bearer { 3gpp charging-id | ggsn-address | imsi | radius-calling-station-id | sgsn-address | sn-rulebase | subscriber-ip-address } | http { host | url } }
end
Configuring Charging Action for Insertion of x-header Fields
Use the following configuration example to configure a charging action for insertion of x-header fields:
configure
active-charging service <acs_service>
charging-action <charging_action_name> [ -noconfirm ]
xheader-insert xheader-format <xheader_format_name> [-noconfirm]
end
Verifying your Configuration
To verify your configuration, in the Exec Mode, enter the following command:
show active-charging xheader-format all
Configuring Post Processing Feature
This section describes how to configure the Post-processing feature to enable processing of packets even if rule matching for them has been disabled.
Use the following configuration example to configure the Post-processing feature:
configure
active-charging service <service_name>
ruledef <ruledef_name>
<protocol> <expression> <operator> <condition>
rule-application post-processing
exit
charging-action <charging_action_name>
...
exit
rulebase <rulebase_name>
action priority <action_priority> { [ dynamic-only | static-and-dynamic | timedef <timedef_name> ] { group-of-ruledefs <ruledefs_group_name> | ruledef <ruledef_name> } charging-action <charging_action_name> [ monitoring-key <monitoring_key> ] [ description <description> ] }
post-processing priority <priority> ruledef <ruledef_name> charging-action <charging_action_name>
...
end
Notes:
l
In the Rulebase Configuration Mode, the ruledef configured for post-processing action must have been configured for post processing in the Ruledef Configuration mode.
l
If the same ruledef is required to be a charging rule in one rulebase and a post-processing rule in another one, then two separate identical ruledefs will have to be defined.
l
Save your configuration as described in the Saving Your Configuration chapter.
l
l
Verifying your Configuration
To verify your configuration, in the Exec Mode, enter the following commands:
To view post-processing ruledef configuration:
show active-charging ruledef post-processing
To view post-processing ruledef statistics:
show active-charging ruledef statistics all post-processing
Configuring Time-of-Day Activation/Deactivation of Rules Feature
This section describes how to configure the Time-of-Day Activation/Deactivation of Rules feature to enable charging according to day/time.
Use the following configuration example to configure the Time-of-Day Activation/Deactivation of Rules feature:
configure
active-charging service <service_name>
ruledef <ruledef_name>
...
exit
timedef <timedef_name> [ -noconfirm ]
start day { friday | monday | saturday | sunday | thursday | tuesday | wednesday } time <hh> <mm> <ss> end day { friday | monday | saturday | sunday | thursday | tuesday | wednesday } time <hh> <mm> <ss>
start time <hh> <mm> <ss> end time <hh> <mm> <ss>
exit
charging-action <charging_action_name>
...
exit
rulebase <rulebase_name>
action priority <action_priority> timedef <timedef_name> { group-of-ruledefs <group_name> | ruledef <ruledef_name> } charging-action <charging_action_name> [ description <description> ]
...
end
Notes:
l
l
If for a timeslot, “start time” > “end time”, that rule will span the midnight. I.e. that rule is considered to be active from the current day till the next day.
l
l
In the following cases a rule will be active all the time:
- a timedef is not configured in an action priority
- a timedef is configured in an action priority, but the named timedef is not defined
- a timedef is defined but with no timeslots
Verifying your Configuration
To verify your configuration, in the Exec Mode, enter the following command:
show active-charging timedef all
Configuring URL Filtering Feature
This section describes how to configure the URL Filtering feature to simplify rules for URL detection.
Use the following configuration example to configure the URL Filtering feature:
To create a group-of-prefixed-URLs:
configure
active-charging service <service_name>
group-of-prefixed-urls <group_name> [ -noconfirm ]
end
To configure the URLs to be filtered in the group-of-prefixed-URLs:
configure
active-charging service <service_name>
group-of-prefixed-urls <group_name>
prefixed-url <url_1>
...
prefixed-url <url_10>
end
To enable or disable the group in the rulebase for processing prefixed URLs:
configure
active-charging service <service_name>
rulebase <rulebase_name>
url-preprocessing bypass group-of-prefixed-urls <group_name>
...
url-preprocessing bypass group-of-prefixed-urls <group_name_n>
end
