Editor
The Traffic Control capabilities of the Service Control Engine (Service Control platform, and the Cisco
Service Control Application for Broadband) are used to limit and prioritize traffic flows. Control of traffic
is based on parameters such as the service of the flow, the package of the subscriber, and the quota state of
the subscriber. This chapter consists of these sections:
• Introduction to Managing Bandwidth, page 1
• Introduction to Managing Virtual Links, page 36
• Introduction to Managing Packages, page 49
• Introduction to Managing Rules, page 57
• Quota Management, page 86
• Unknown Subscriber Traffic , page 103
Introduction to Managing Bandwidth
The upstream and downstream interfaces are each assigned one default global controller. You can add additional
global controllers.
The number of global controllers a service configuration can contain varies based on the Cisco SCE hardware.
The maximum number of global controllers including the default global controllers are:
• Cisco SCE 8000 multi-Gigabit Ethernet—1024 upstream and 1024 downstream
• Cisco SCE 8000 10 Gigabit Ethernet—4096 upstream and 4096 downstream
After you have defined global controllers, you can add subscriber BW controllers (BWCs) to packages, and
map these subscriber BWCs to different global controllers.
Note
In release 3.7.5, the global bandwidth controller for IPv6 works in the subscriberless mode. The IPv6
traffic is mapped to a default subscriber (N/A). Bandwidth control should be performed on the Unknown
Subscriber Package. The maximum and the default package ID of the Unknown Subscriber value is 4999.

Managing Global Bandwidth Overview
Note
If you enable or disable Virtual Links mode, all user-defined global controllers are deleted from the service
configuration. A subscriber BWC that pointed to a user-defined global controller now points to the default
global controller. (Other parameters of these subscriber BWCs remain unchanged.)
Managing Global Bandwidth Overview
The upstream and downstream interfaces are each assigned one default global controller that, by default,
controls the total link traffic. Based on the Cisco SCE hardware, the number of global controllers you can add
to a service configuration varies. For details, see the Introduction to Managing Bandwidth, on page 1
section.
You can also define the bandwidth total link limit to be less than the physical capacity of the Cisco SCE
platform for each interface separately. When another device that has limited BW capacity is next to the Cisco
SCE platform on the IP stream, you can have this limitation enforced in a policy-aware manner by the Cisco
SCE platform, instead of having it enforced arbitrarily by the other device.
Viewing Global Controller Settings
Note
Global controller bandwidth is based on Layer 1 volume. Accounting, reporting, and subscriber bandwidth
control in Cisco SCA BB is based on Layer 3 volume.
Procedure
In the Policies tab, click Global Policy .

Filtering Global Controllers
The main part of the pane contains the Upstream area listing upstream global controllers and the Downstream
area listing downstream global controllers. Each list has two columns:
• Upstream or Downstream —Displays the hierarchy of global controllers, bandwidth controllers, and
service rules. Each global controller has the bandwidth controllers that are connected to it listed as
children. Each bandwidth controller has the service rules associated with it listed as children.
• Policy Description—Summarizes the details of the global controller, bandwidth controller, or service
rule in the corresponding column. In the rows containing the global controller details, the maximum
bandwidth value permitted to this global controller is displayed.
For each global controller, you can set different values for the maximum bandwidth for each of the four time
frames defined by the default calendar. For details, see Managing Calendars Overview , on page 79 section.
• A single value in this field indicates that the maximum bandwidth for this global controller is constant.
• If each time frame has a different maximum bandwidth, the maximum bandwidth for each time frame
is displayed, separated by commas.
Figure 2: Time Frame Display
• If two time frames have the same maximum bandwidth, the value is not repeated. (So 40,,,100 means
that the first three time frames have a maximum bandwidth of 40 percent of the total link limit, and the
fourth time frame has a maximum bandwidth equal to the total link limit.)

of the other device.

Introduction to Defining Global Controllers
In both systems, you can define each link separately with equal rates or you can define each link separately
with different rates.
Alternatively, you can apply bandwidth limitations as an aggregate for all links or as an aggregate with
individual control of each links.
You can:

Control each link separately without with different rate per link.
Control the links in aggregate and in addition maximum rate per-link, which is equal between all links.
Control the links in aggregate and in addition maximum rate per-link, which is different between the links.
Control the links in Virtual Link mode.
Note
If Virtual Links mode is enabled, bandwidth limitations are applied to the sum of the all links.
Note
Any attempt to change the global controller bandwidth for invalid link results in an error message during
apply policy, similar to the following: “Invalid value set on Link ID 6 for upstream GC ‘Default Global
Controller’. Link ID 6 does not exist. Available Link IDs: 1, 2, 3, 4”
To activate the respective edit dialog of the Global Controller settings:
• Double click on a global controller row in the global controller table view on the right main panel of the

In this link control mode, the maximum bandwidth is the sum of links but bandwidth settings can be configured
for each link up the maximum bandwidth for all links. When you create a GC in this mode you can configure
the aggregate global controller of the link and in addition specify a bandwidth limitation per link. This mode
is used when the Cisco SCE serves multiple edge devices and you want to enforce two rules: One aggregate
rule on all the links together and one rule per specific link. In this mode, you can enforce bandwidth limitation
on the sum of all links and enable separate bandwidth settings for each link. You can control the links in
aggregate and set maximum rate per-link which is different between the links.
Use the following procedure to configure global controller as the sum of all links with a different rate per

Introduction to Managing Subscriber Bandwidth
Introduction to Managing Subscriber Bandwidth
After you have defined global controllers, you can add subscriber BWCs to packages and map these subscriber
BWCs to different global controllers.
A Subscriber BWC controls subscriber bandwidth consumption for upstream or downstream flows. It controls
and measures the bandwidth of an aggregation of traffic flows of a service or group of services.
Each package has its own set of BWCs that determine the bandwidth available per package subscriber for
each available service.
The two Primary BWCs, one for upstream traffic and one for downstream traffic, allocate bandwidth to specific
subscribers. Bandwidth is allocated based on the Committed Information Rate (CIR), the Peak Information
Rate (PIR), and the Subscriber relative priority settings. You can configure these parameters, but the Primary
BWCs cannot be deleted.
There are two default BWCs, one for upstream traffic and one for downstream traffic. By default, all services
are mapped to one of these two BWCs. The BWC mechanism controls rate subpartitioning within the default
BWC rate control, based on the CIR, PIR, and AL. You can configure these parameters, but the default BWCs
cannot be deleted.
You can add up to 32 user-defined BWCs per package:
• Subscriber BWCs operate at the service-per-subscriber level. They allocate bandwidth for services for
each subscriber, based upon the CIR, PIR, global controller, and Assurance Level (AL) set for the BWC.
Each rule defines a link between the flow of the service and one of the BWCs (unless the flows are to
be blocked). See Defining Per-Flow Actions for a Rule , on page 60 section.
• Extra BWCs also operate at the subscriber level. Extra BWCs (based on the CIR, PIR, global controller,
and AL) can be allocated for services that are not included in the Primary BWC. These are services that
are not often used but have strict bandwidth requirements, for example, video conference calls. The
Extra BWCs are BWCs that control a single service (or service group). BWCs cannot borrow bandwidth
from Extra BWCs and vice versa.
Each user-defined BWC controls either downstream or upstream traffic.
Note
If you enable or disable Virtual Links mode, all user-defined global controllers are deleted from the service
configuration. A BWC that pointed to a user-defined global controller now points to the default global
controller. Other parameters of these BWCs remain unchanged.
The Cisco SCE supports a maximum of 2000 BWCs. You cannot apply a PQB file to a Cisco SCE if the file
contains more than 2000 BWCs. But, the Subscriber BWCs with same values for GC Index, AL Level, PIR,
and CIR are considered as a single BWC; even if the BWCs are mapped to different flows. So, in effect, Cisco
SCA BB may support more than 2000 BWCs.
Subscriber BWC Parameters
The Subscriber BW Controllers tab of the Package Settings dialog box has the following configuration
parameters:
• Name—A unique name for each BWC.
• CIR (L3 Kbps)—The minimum bandwidth that must be granted to traffic controlled by the BWC.
Cisco Service Control Application for Broadband (Cisco SCA BB) User Guide
22
Traffic Control Using the Service Configuration Editor
Introduction to Managing Subscriber Bandwidth
• PIR (L3 Kbps)—The maximum bandwidth allowed to traffic controlled by the BWC.
Note
The minimum bandwidth for a subscriber BWC is 16 Kbps with a granularity of 1 Kbps
and the maximum bandwidth is 500000 Kbps.
• Global Controller—The global controller with which this BWC is associated. The global controllers are
virtual queues that are part of the bandwidth control mechanism. Direct traffic with similar bandwidth
control properties to the same global controller.
• Assurance Level—How fast bandwidth either decreases from the PIR to the CIR as congestion builds
or else increases from the CIR to the PIR as congestion decreases. A higher AL ensures a higher bandwidth
compared to a similar BWC with a lower AL. The lowest assurance value is 1, the highest is Persistent
(10).
Assurance Level 10 (persistent) never goes below the relevant CIR, unless the total line rate cannot
sustain this value.
• Subscriber relative priority—Assurance Level given to the Primary BWC of the subscriber. It determines
the assurance given to all the subscriber traffic when competing for bandwidth with subscribers to other
packages. The lowest value is 1; the highest is 10.
Note
Subscriber bandwidth control (and accounting and reporting) is based on Layer 3 volume. Global controller
bandwidth is based on Layer 1 volume.

The effect of Assurance Level on bandwidth allocation for subscriber BWCs will be as follows:
If there are 4 BWCs namely “Priority”, “Gold”, “Silver” and “default” with Assurance Levels 9, 6, 3 and 1
respectively, the “priority” BWC gets the bandwidth first, followed by the "Gold" and the "Silver" BWC. The
“default” BWC will be the last to get the bandwidth.

Configuring Total Bandwidth Control
Procedure
Step 1
Configure the necessary global controllers.
Ascertain which services are likely to be problematic, and what the maximum total bandwidth should be for
each. You do not need to configure services and packages that are unlikely to be problematic; you can include
them in the default global controllers.
Step 2
Step 3
Configure the subscriber BWCs for the package.
Add a subscriber BWC for each type of upstream or downstream traffic that you want to limit, and configure
the CIR and the PIR accordingly.
Select an appropriate global controller for each subscriber BWC.
Step 4
Step 5
For each service that is to have its own BWC, create a rule and select appropriate upstream and downstream
BWCs.

Introduction to Managing Virtual Links
In Virtual Links mode, template bandwidth controllers are defined for packages. Actual bandwidth parameters
are assigned when a subscriber enters the system. This bandwidth depends on the package of the subscriber
and the physical link assigned to the subscriber. The package of the subscriber defines the template controllers.
For each service configuration that has Virtual Links mode enabled, there is one default upstream virtual link
and one default downstream virtual link. The upstream and downstream interfaces are each assigned one
default template global controller.
You can add additional template global controllers. You can add, modify, and delete virtual links using a
command-line interface (CLI).
Cisco Service Control Application for Broadband (Cisco SCA BB) User Guide
36
Traffic Control Using the Service Configuration Editor
Collection Manager Virtual Links Names Utility
The number of directional template global controllers limits the maximum number of virtual links. The number
of template global controllers times the number of virtual links cannot exceed 1024 or 4096. Based on the
Cisco SCE hardware, the number of global controllers varies. For details, see the Introduction to Managing
Bandwidth, on page 1section.
To support the DOCSIS 3.0 Downstream bonding, a two level virtual link hierarchy is created for the wideband
channels. The wideband channels are associated with the Aggregate Global Control (AGC) that provides a
constant output signal despite variations in input signal strength. Wideband channels are associated with three
AGCs in a two level hierarchy. At the lower level of the hierarchy, all the DOCSIS 3.0 modems for wideband
are aggregated into one AGC and the other AGC contains both legacy and 3.0 modems. The AGC at the top
level of the hierarchy is used to limit the aggregated bandwidth of the wideband channel.
For more information on the support for DOCSIS 3.0 solution, see the Cisco Service Control for Managing
Remote Cable MSO Links Solution Guide.
For more information on managing the virtual links global controllers, see the Managing Virtual Links Global
Controllers section.
Note
If you enable or disable Virtual Links mode, all user-defined global controllers are deleted from the service
configuration. A subscriber BWC that pointed to a user-defined global controller now points to the default
global controller. (Other parameters of these subscriber BWCs remain unchanged.)
Note
While applying a policy in virtual link mode, if the new template includes a different number of global
controllers than the currently applied template, you must choose the Reset all Virtual Links to Template
Rate Limits. Otherwise, selecting apply results in en error message, similar to the following: “Template
Upstream Virtual Link differ from the one in the SCE - cannot apply without the force template virtual
link option.”
Collection Manager Virtual Links Names Utility
The Cisco Service Control Collection Manager includes a command-line utility for managing the names of
virtual links.
For more information about the Cisco Service Control Collection Manager Virtual Links Names Utility, see
the “Managing Virtual Links” section in the “Managing the Collection Manager” chapter of Cisco Service
Control Management Suite Collection Manager User Guide .

Introduction to Managing Packages
A package is a description of subscriber policy. It is a collection of rules that defines the reaction of the system
when it encounters flows that are mapped to the service to which the rule is related. It is recommended that
you first define services (see Introduction to Managing Services section) and only then add and define packages.
Every Cisco SCA BB service configuration contains a package, the default package, which is the root package
and cannot be deleted.
A subscriber is mapped to the default package in one of the following conditions:
• No other package is specifically assigned to the subscriber
• A nonexistent package is assigned to the subscriber.
A service configuration can contain up to 5000 packages.
Package Parameters
The following parameters define a package:
• General parameters:
◦Package Name—A unique name for the package
◦Description—(Optional) A description of the package
• Quota Management parameters:
◦Quota Management Mode—Specifies how the subscriber quotas are managed—by external quota
manager or replenished periodically by Cisco SCA BB.
◦Aggregation Period Type—The quota aggregation period used when quotas are replenished
periodically.
◦Quota Buckets—16 resource buckets used for quota management.
• Subscriber BW Controllers parameters:
◦Subscriber relative priority—The relative priority given to subscribers of the package at times of
Network congestion.
Separate priorities are defined for upstream and downstream flows.
◦Subscriber Bandwidth Controllers—A list of BW controllers (BWCs) that are available to services
that are part of the package. Various parameters are defined for each BWC, including a mapping
to a global controller.
Separate BWCs are defined for upstream and downstream flows.
• Advanced parameters:
Cisco Service Control Application for Broadband (Cisco SCA BB) User Guide

Traffic Control Using the Service Configuration Editor
Viewing Packages
◦Package Index—The unique number by which the system recognizes a package. Changing the
package name does not affect Cisco SCE platform activity. The system provides a default value
of the package index. Do not modify this value.
◦Parent Package—The package one level higher in the package hierarchy. The parent package is
important when packages share usage counters. The default package is the base of the package
hierarchy, and does not have a parent.
◦Package Usage Counter—Used by the system to generate data about the total use by each package.
A package can use either an exclusive package usage counter or the package usage counter of the
parent package.
Each usage counter has:
◦A name assigned by the system (based on the package name).
Note
An asterisk is appended to a package usage counter name whenever the counter applies
to more than one package.
◦A unique counter index—The system provides a default value of the counter index. Do not
modify this value.
◦Calendar—The calendar used as the basis for the time-based rules of the package.
◦VAS Traffic Forwarding Table—The forwarding table used by the package.
These parameters are defined when you add a new package (see Adding Packages, on page 51 section). You
can modify them at any time (see Editing Packages, on page 55 section).

Step 3
Click Yes.
The package is deleted and is no longer displayed in the package tree.
Introduction to Managing Rules
After you have defined services and basic packages, you can define rules for the package.
You can configure rules to do some or all of the following:
• Block the service
• Define maximum bandwidth for the service
• Change the DSCP ToS value of packets in a flow
• Set a quota for the service
• Define behavior when the quota for this service is breached
A rule usually applies at all times. To allow additional flexibility, you can divide the week into four separate
time frames. You can define subrules—time-based rules—for each time frame.
Note
In Cisco SCA BB, the maximum number of unique rules that can be applied is limited to 5000. If the
number of unique rules exceeds the maximum limit, an error occurs. The number of unique rules are
identified from the Package ID, Service, and Timeframe fields.
The Default Service Rule
A default service rule is assigned to every package. It cannot be deleted or disabled.
Cisco Service Control Application for Broadband (Cisco SCA BB) User Guide
57
Traffic Control Using the Service Configuration Editor
Rule Hierarchy
The default values of this rule are:
• Admit (do not block) traffic.
• Map traffic to the default BWCs.
• Do not limit quotas for either upstream or downstream traffic.
Rule Hierarchy
The Cisco SCE platform applies the most specific rule to any flow.
For example, if you define rules for E-Mail and POP3:
• Any flow mapped to the SMTP or IMAP service is handled according to the e-mail rule.
• Any flow mapped to the POP3 service is handled according to the POP3 rule
This means, for example, that POP3 can have its own usage limits, whereas SMTP and IMAP must share
usage limits.
Note
If you add a rule for a child service, the settings for the parent rule are not copied to the new rule. All new
rules start with default values.
Indicates any rule that also applies to child services.
Indicates any rule that does not apply to any child services.
Indicates a global rule.
Time-based rules are shown as children of the relevant rule. The icon for a time-based rule also shows if
the rule applies to child services ( or ).
See also “How to Display the Services Affected by a Rule” section.
Viewing the Rules of a Package
You can view a list of the rules of a package.
The listing for each rule includes an icon, the name of the service or group of services to which the rule applies,
whether the rule is enabled or disabled, and a brief description of the rule.
Procedure
In the Policies tab, select a package from the package tree.
A list of all rules defined for this package is displayed in the right (Rule) pane.

Time-Based Rules Overview
The Console allows you to divide the week into four time frames (see “Managing Calendars” section). A
time-based rule is a rule that applies to one time frame.
You can add time-based rules to any rule. If a time-based rule is not defined for a time frame, the parent rule
is enforced.
Often, you want the rules for the different time frames to be similar. When you add a time-based rule, the
settings of the parent rule are copied to the new time-based rule; you can make any needed changes. Subsequent
changes to the parent rule do not affect the time-based rule.
You must define the calendar before defining the related time-based rules.
Adding Time-Based Rules to a Rule
Adding a time-based rule to a rule allows you to specify alternate rule parameters applicable only for a specific
time frame. If a time-based rule is not defined for a time frame, the parent rule is enforced.
• When you add a time-based rule, all parameters are initially set to the values defined for the parent rule.
Subsequent changes to the parent rule do not change the time-base rule.

Cisco Service Control Application for Broadband (Cisco SCA BB) User Guide
79
Traffic Control Using the Service Configuration Editor
Global Rules
After you have configured a calendar, you can add time-based rules to a package that uses the calendar. A
time-based rule is a rule that applies to only one time frame. Time-based rules allow you to set rule parameters
that apply only at specific times. You might, for example, want to define different rules for peak, off-peak,
nighttime, and weekend usage.
Each service configuration includes one default calendar. You can add nine more calendars, each with a
different time-frame configuration. You can use different calendars for different packages. You can also use
different calendars where a service provider has customers in more than one time zone by configuring calendars
with a one-hour offset from each other.

How to Manage DSCP ToS Marker Values
Cisco SCA BB can change the value of the DSCP ToS marker of packets of flows that match a filter rule or
a service rule.
For details on how to change the value of the DSCP ToS marker, see the following steps:
• For Filter Rule—see Step 11 of “How to Add Filter Rules” section
• For Service Rule—see Steps 10 and 11 of “How to Define Per-Flow Actions for a Rule” section and
Step 9 of “How to Edit Breach-Handling Parameters for a Rule” section

Global Rules
Cisco SCA BB supports seven ToS Marker Classes. You assign each class a specific value to apply to the
packets of a flow.
Note
If you have used DSCP marking on a Cisco SCA BB release before 3.1.5 and you are converting your old
service configurations, you must reconfigure the service configurations to obtain the same network behavior
as in the former release.
Configuring DSCP ToS Marking
DSCP ToS marking is used in IP networks as a means to signal the type and priority of a flow between network
elements.
The default marking option is not to mark the packet. The classification may take a few packets to finalize.
So after the ToS marking is enabled, the first few packets may still be processed under the default option and
therefore may not be marked.
Note
In an MPLS environment, the Cisco SCE platform does not map the DSCP bits to the EXP bits of the
MPLS header.
Procedure
Step 1
From the Policies tab of the left pane, choose Configuration > Policies > ToS Marking Settings .
The ToS Marking Settings dialog box appears.
Figure 67: ToS Marking Settings
Step 2
(Optional) To enable DSCP ToS marking on upstream flows, check the Enable Upstream ToS Marking check
box.

Quota Management
If Upstream ToS Marking is disabled, it overrides filter rule and service rule settings.
Step 3
(Optional) To enable DSCP ToS marking on downstream flows, check the Enable Downstream ToS Marking
check box.
If Downstream ToS Marking is disabled, it overrides filter rule and service rule settings.
Step 4
Give unique names to the ToS Marker Classes.
Note
You can use the default names for the ToS Marker Classes, but it is recommended that you provide
meaningful names.
Assign values to the ToS Marker Classes.
Values must be in the range from 0 to 63.
Step 5
When defining filter rules and service rules, the names and values of ToS Marker Classes are displayed
in drop-down lists in the format “name [value]”. For example, “ToS 1 [23]” or “My P2P ToS [1]”
Click OK .
Your changes are saved.

Quota Replenish Scatter
By default, if subscriber quota is replenished using periodical quota management, the quota of all subscribers
is replenished at the same time. To smooth quota replenishment, you can scatter the time of quota replenishment.
Cisco Service Control Application for Broadband (Cisco SCA BB) User Guide
95
Traffic Control Using the Service Configuration Editor
Selecting Quota Buckets for Rules
To activate this feature, enter a non-zero value for the Length of the time frame for quota replenish scatter
(minutes) property of the Advanced Options tab of the Systems Settings dialog box (see “Managing Advanced
Service Configuration Options” section). By default, this property has a value of zero, that is, all quota is
replenished at the same time.
Quota for each subscriber is replenished at a random time within the quota replenish scatter time frame, with
replenish events split evenly before and after the quota aggregation time.
Best results are obtained if the scatter time frame is the same length as the quota aggregation period, which
should completely smooth replenish events. Do not enter a value larger than the quota replenish period.
Therefore, for an hourly quota replenish period, set the scatter to 60 minutes.
The quota replenish scatter function is independent of all other quota management parameters.
Selecting Quota Buckets for Rules
Select the quota buckets that the flows mapped to a rule uses. The quota buckets are defined during package
setup (see “How to Edit Quota Management Settings for Packages” section ). If no quota bucket is appropriate
for the rule, add a new quota bucket to the package or edit an existing bucket.

Breach-Handling Parameters
The following are the configuration parameters in the Breach Handling tab of the Edit Rule for Service Settings
dialog box.
• You determine what happens to flows identified as belonging to this rule when a quota is breached:
◦No changes to active control—Flows mapped to this rule are not affected when quota is breached.
Cisco SCA BB can generate Quota Breach RDRs even when this option is selected (see “How to
Manage Quota RDRs” section).
◦Block the flow—Flows mapped to this rule are blocked when quota is breached.
Redirect to—Redirect the flow to a specified, protocol-dependent URL, where a posted web page explains
the reason for the redirection. URL redirection sets are defined in the System Settings dialog box. (See “How
Cisco Service Control Application for Broadband (Cisco SCA BB) User Guide
101
Traffic Control Using the Service Configuration Editor
Example for Creating Tiered Subscriber Services
to Add a Set of Redirection URLs” section.) Only three protocol types support redirection: HTTP, HTTP
Streaming, and RTSP. Redirection is not supported when unidirectional classification is enabled.
• Control the flow characteristics—The behaviors of flows mapped to this rule change when quota is
breached:
Select an upstream Bandwidth Controller—Map the traffic flow of this rule to a specific upstream BW
controller (BWC). This sets up bandwidth metering of all concurrent flows mapped to this rule, based on the
characteristics of the selected BWC.
Select a downstream Bandwidth Controller—The same functionality as the previous option, but for downstream
flow.
Limit the flow’s upstream bandwidth—Set a per-flow upstream bandwidth limit (for flows mapped to the
service of this rule).
Limit the flow’s downstream bandwidth—Set a per-flow downstream bandwidth limit.
Set the flow's upstream packets ToS—Set the DSCP ToS marker of all packets of upstream flows.
Set the flow's downstream packets ToS—Set the DSCP ToS marker of all packets of downstream flows.
Limit concurrent flows of this Service—Set the maximum number of concurrent flows (mapped to this rule)
permitted to a subscriber.
• Activate a Subscriber Redirect—Activate a Subscriber Redirect when subscribers exceed their quota
limit.
• Activate a Subscriber Notification—Activate a Subscriber Notification when subscribers exceed their
quota limit. This notification can, for example, convey the quota breach situation to the subscriber and
explain how to obtain additional quota.
Note
Subscriber notification is not supported when unidirectional classification is enabled.
To define Subscriber Notifications, see “Managing Subscriber Notifications” section.
• Activate Traffic Mirroring—Activate traffic mirroring when subscribers exceed their quota limit
Example for Creating Tiered Subscriber Services
Tiered subscriber services can be implemented using the Cisco SCA BB Console. Because the definition of
such services is open ended, this section describes how to define two of the tiers outlined in the value proposition
description. The two tiers are defined as follows:
• Silver
◦Weekly bandwidth limited to 4.2 GB (corresponds to a daily limit of 600 MB)
◦Email and browsing services are limited to 256 kbps
◦Audio and video streaming services are limited to 64 kbps
◦P2P services are limited to 28 kbps
• Gold

102
Traffic Control Using the Service Configuration Editor
Unknown Subscriber Traffic
◦Weekly bandwidth limited to 5.6 GB (corresponds to a daily limit of 800 MB)
◦Email and browsing services are not bandwidth limited
◦Audio and video streaming services are limited to 128 kbps
◦P2P services are limited to 28 kbps
The following steps are applicable to both the 'Silver' and 'Gold' packages.
Procedure
Step 1
Step 2
Step 3
Create a new package as described in “How to Add Packages” section.
Enable periodical (internal) quota management.
Set the aggregation period to Daily
Step 4
Set the quota limit to the desired value and give the quota bucket a meaningful name
For further information, see “How to Edit Quota Management Settings for Packages” section.
Step 5
Add the bandwidth controllers for the required services and set the PIR to the desired rate.
Note
Each service that is bandwidth limited requires a sub bandwidth controller that is a child of the primary
bandwidth controller, not an extra bandwidth controller.
For further information, see “How to Edit Package Subscriber BWCs” section .
Step 6
Add a rule to the package for each bandwidth limited service.
For further information, see “How to Add Rules to a Package” section .
Step 7
Configure the rule to control the characteristics of the flow with the bandwidth controller for the relevant
service.
For further information, see “How to Define Per-Flow Actions for a Rule” section .
Step 8
Set the usage limit for the package to use the quota bucket defined in Step 2.
For further information, see the “How to Select Quota Buckets for Rules” section section.
Unknown Subscriber Traffic
Cisco SCE platform processes a traffic flow that does not match any filter rule (see “Filtering the Traffic
Flows” section on page 10-23 ). Cisco SCE platform tries to identify the subscriber responsible for the traffic
flow. The platform checks its internal database for a subscriber identified by the IP address or VLAN tag of
the traffic flow. If no such subscriber exists, the traffic flow is mapped to the Unknown Subscriber Traffic
category.
The Unknown Subscriber Traffic category is included in the tree in the Network Traffic tab but is not part of
the package hierarchy. The Unknown Subscriber Traffic category cannot be deleted.
Note
Traffic of one unknown subscriber cannot be distinguished from traffic of other unknown subscribers.
Therefore, you cannot set either per-subscriber usage limits or subscriber-level metering with subscriber
BWCs. You can use subscriber BWCs only to link a selected service to a global controller.
Cisco Service Control Application for Broadband (Cisco SCA BB) User Guide
103
Traffic Control Using the Service Configuration Editor
Unknown Subscriber Traffic
The Unknown Subscriber Traffic category behaves like a package with the following parameters:
• Package Name = Unknown Subscriber Traffic
• Package Index = 4999
• One package usage counter:
◦Counter Name = Unknown Subscriber Traffic Counter
◦Counter Index = 1023
You can:
• Edit the Unknown Subscriber Traffic package settings:
◦Add extra BWCs (see “How to Edit Package Subscriber BWCs” section).
◦Select a calendar (see “How to Set Advanced Package Options” section).
• Edit the default service rule for the Unknown Subscriber Traffic category:
◦Change the Rule State (see “How to Edit Rules” section).
◦Change per-flow actions for the rule (see “How to Define Per-Flow Actions for a Rule” section).
• Add rules to the Unknown Subscriber Traffic package:
◦Add rules (see “How to Add Rules to a Package” section); edit (see “How to Edit Rules” section)
and delete (see “How to Delete Rules” section) these rules.
◦Add time-based rules (see “How to Add Time-Based Rules to a Rule” section); edit (see “How to
Edit Time-Based Rules” section) and delete (see “How to Delete Time-Based Rules” section) these
rules.
