CHAPTER 1

General Overview

This chapter provides a general overview of the Cisco Service Control solution. It introduces the
Cisco Service Control concept and the Service Control capabilities. It also briefly describes the
hardware capabilities of the Service Control Engine (SCE) platform and the Cisco specific
applications that together compose the total Cisco Service Control solution.

This chapter contains the following sections:

• The Cisco Service Control Concept 1-1

• Cisco Service Control Capabilities 1-2

• The SCE Platform 1-3

• Management and Collection 1-4

The Cisco Service Control Concept

The Cisco Service Control solution is delivered through a combination of purpose-built hardware
and specific software solutions that address various service control challenges faced by service
providers. The SCE platform is designed to support classification, analysis, and control of
Internet/IP traffic.

Service Control enables service providers to create profitable new revenue streams while
capitalizing on their existing infrastructure. With the power of Service Control, service providers
have the ability to analyze, charge for, and control IP network traffic at multigigabit wire line
speeds. The Cisco Service Control solution also gives service providers the tools they need to
identify and target high-margin content-based services and to enable their delivery.

As the downturn in the telecommunications industry has shown, IP service providers’ business
models need to be reworked to make them profitable. Having spent billions of dollars to build
ever larger data links, providers have incurred massive debts and faced rising costs. At the same
time, access and bandwidth have become commodities where prices continually fall and profits
disappear. Service providers have realized that they must offer value-added services to derive
more revenue from the traffic and services running on their networks. However, capturing real
profits from IP services requires more than simply running those services over data links; it
requires detailed monitoring and precise, real-time control and awareness of services as they are
delivered. Cisco provides Service Control solutions that allow the service provider to bridge this
gap.

OL-7826-05 1-1

Cisco SCE 2000 4/8xFE Installation and Configuration Guide

Cisco Service Control Capabilities

Service Control for Broadband Service Providers

Service providers of any access technology (DSL, cable, mobile, and so on) targeting residential
and business consumers must find new ways to get maximum leverage from their existing
infrastructure, while differentiating their offerings with enhanced IP services.

The Cisco Service Control Application for Broadband adds a new layer of service intelligence and
control to existing networks that can:

• Report and analyze network traffic at subscriber and aggregate level for capacity planning

• Provide customer-intuitive tiered application services and guarantee application SLAs

• Implement different service levels for different types of customers, content, or applications

• Identify network abusers who are violating the Acceptable Use Policy

• Identify and manage peer-to-peer, NNTP (news) traffic, and spam abusers

• Enforce the Acceptable Use Policy (AUP)

• Integrate Service Control solutions easily with existing network elements and BSS/OSS

systems

Chapter 1 General Overview

Cisco Service Control Capabilities

The core of the Cisco Service Control solution is the purpose-built network hardware device: the
Service Control Engine (SCE). The core capabilities of the SCE platform, which support a wide
range of applications for delivering Service Control solutions, include:

• Subscriber and application awareness—Application-level drilling into IP traffic for real-time

understanding and controlling of usage and content at the granularity of a specific subscriber.

• Subscriber awareness—The ability to map between IP flows and a specific subscriber in

order to maintain the state of each subscriber transmitting traffic through the SCE
platform and to enforce the appropriate policy on this subscriber’s traffic.

Subscriber awareness is achieved either through dedicated integrations with subscriber
management repositories, such as a DHCP or a Radius server, or via sniffing of Radius or
DHCP traffic.

• Application awareness—The ability to understand and analyze traffic up to the application

protocol layer (Layer 7).
For application protocols implemented using bundled flows (such as FTP, which is

implemented using Control and Data flows), the SCE platform understands the bundling
connection between the flows and treats them accordingly.

• Application-layer, stateful, real-time traffic control—The ability to perform advanced control

functions, including granular BW metering and shaping, quota management, and redirection,
using application-layer stateful real-time traffic transaction processing. This requires highly
adaptive protocol and application-level intelligence.

• Programmability—The ability to quickly add new protocols and easily adapt to new services

and applications in the ever-changing service provider environment. Programmability is
achieved using the Cisco Service Modeling Language (SML).

Cisco SCE 2000 4/8xFE Installation and Configuration Guide

1-2 OL-7826-05

Chapter 1 General Overview

Programmability allows new services to be deployed quickly and provides an easy upgrade

path for network, application, or service growth.

• Robust and flexible back-office integration—The ability to integrate with existing third-party

systems at the Service Provider, including provisioning systems, subscriber repositories,

billing systems, and OSS systems. The SCE provides a set of open and well-documented APIs

that allows a quick and robust integration process.

• Scalable high-performance service engines—The ability to perform all these operations at

wire speed.

The SCE Platform

The SCE family of programmable network devices is capable of performing application-layer
stateful-flow inspection of IP traffic, and controlling that traffic based on configurable rules. The
SCE platform is a purpose-built network device that uses ASIC components and RISC processors
to go beyond packet counting and delve deeper into the contents of network traffic. Providing
programmable, stateful inspection of bidirectional traffic flows and mapping these flows with user
ownership, the SCE platforms provide real-time classification of network usage. This information
provides the basis of the SCE platform advanced traffic-control and bandwidth-shaping
functionality. Where most bandwidth shaper functionality ends, the SCE platform provides more
control and shaping options, including:

The SCE Platform

• Layer 7 stateful wire-speed packet inspection and classification

• Robust support for over 600 protocols and applications, including:

• General—HTTP, HTTPS, FTP, TELNET, NNTP, SMTP, POP3, IMAP, WAP, and others

• P2P file sharing—FastTrack-KazaA, Gnutella, BitTorrent, Winny, Hotline, eDonkey,

DirectConnect, Piolet, and others

• P2P VoIP—Skype, Skinny, DingoTel, and others

• Streaming and Multimedia—RTSP, SIP, HTTP streaming, RTP/RTCP, and others

• Programmable system core for flexible reporting and bandwidth control

• Transparent network and BSS/OSS integration into existing networks

• Subscriber awareness that relates traffic and usage to specific customers

Management and Collection

The following diagram illustrates a common deployment of an SCE platform in a network.

Figure 1-1: SCE Platform in the Network

Chapter 1 General Overview

Management and Collection

The Cisco Service Control solution includes a complete management infrastructure that provides
the following management components to manage all aspects of the solution:

• Network management

• Subscriber management

• Service Control management

These management interfaces are designed to comply with common management standards and to
integrate easily with existing OSS infrastructure.

Figure 1-2: Service Control Management Infrastructure

Cisco SCE 2000 4/8xFE Installation and Configuration Guide

1-4 OL-7826-05

Chapter 1 General Overview

Network Management

Cisco provides complete network FCAPS (Fault, Configuration, Accounting, Performance,
Security) Management.

Two interfaces are provided for network management:

• Command-line interface (CLI)—Accessible through the Console port or through a Telnet

connection, the CLI is used for configuration and security functions.

• SNMP—Provides fault management (via SNMP traps) and performance monitoring

functionality.

Subscriber Management

Where the Cisco Service Control Application for Broadband (SCA BB) enforces different policies
on different subscribers and tracks usage on an individual subscriber basis, the Cisco Service
Control Management Suite (SCMS) Subscriber Manager (SM) may be used as middleware
software for bridging between the OSS and the SCE platforms. Subscriber information is stored in
the SM database and can be distributed between multiple platforms according to actual subscriber
placement.

Management and Collection

The SM provides subscriber awareness by mapping network IDs to subscriber IDs. It can obtain
subscriber information using dedicated integration modules that integrate with AAA devices, such
as Radius or DHCP servers.

Subscriber information may be obtained in one of two ways:

• Push Mode—The SM pushes subscriber information to the SCE platform automatically upon

logon of a subscriber.

• Pull Mode—The SM sends subscriber information to the SCE platform in response to a query

from the SCE platform.

Service Configuration Management

Service configuration management is the ability to configure the general service definitions of a
service control application. A service configuration file containing settings for traffic
classification, accounting and reporting, and control is created and applied to an SCE platform.
The SCA BB application provides tools to automate the distribution of these configuration files to
SCE platforms. This simple, standards-based approach makes it easy to manage multiple devices
in a large network.

Service Control provides an easy-to-use GUI to edit and create these files and a complete set of
APIs to automate their creation.

OL-7826-05 1-5

Cisco SCE 2000 4/8xFE Installation and Configuration Guide

Management and Collection

Data Collection

The Cisco Service Control solution generates usage data and statistics from the SCE platform and
forwards them as Raw Data Records (RDRs), using a simple TCP-based protocol (RDR­Protocol). The Cisco Service Control Management Suite (SCMS) Collection Manager (CM)
software implements the collection system, listening in on RDRs from one or more SCE
platforms and processing them on the local machine. The data is then stored for analysis and
reporting functions, and for the collection and presentation of data to additional OSS systems such
as billing.

CHAPTER 3

T opology

This chapter describes the possible deployment topologies of the SCE 2000. The Cisco SCE
solution offers a number of basic topology options that permit the user to tailor the SCE Platform
to fit the needs of a particular installation. An understanding of the various issues and options is
crucial to designing, deploying, and configuring the topology that best meets the requirements of
the individual system.

This chapter contains the following sections:

• The SCE 2000 Platform 3-1

• Topology Considerations 3-1

• Physical T opologies 3-4

The SCE 2000 Platform

The SCE 2000 introduces a solution for dual links with load sharing and asymmetrical routing
and support for fail-over between two SCE platforms.

The SCE 2000 supports wire speed processing of full-duplex 2-Fast Ethernet streams. The SCE
2000 can, therefore, be deployed in a multi-link environment, either in a single or dual SCE
platform topology.

• single SCE 2000 topology — Provides increased network capacity and the ability to process

both directions of a bi-directional flow, processing both the upstream and downstream paths

of a flow, even if they traverse different links

• dual SCE 2000 topology (cascade) — cascaded SCE 2000s provide high-availability and fail-

over solution and maintain the line and service in case of SCE 2000 failure.

T opology Considerations

There are several issues that must be considered in order to arrive at the optimum configuration of
the topology-related parameters:

• Functionality — Will the system be used solely to monitor traffic flow, with report

functionality only, or will it be used for traffic flow control, with enforcement as well as

report functionality?

OL-7826-05 3-1

Cisco SCE 2000 4/8xFE Installation and Configuration Guide

Topology Considerations

• Number of links — The SCE 2000 may be connected to one or two FE links. This is relevant

for both Inline and Receive-Only topologies.

• Redundancy — Must the system be designed to guarantee uninterrupted SCE 2000

functionality? If so, there must be a backup SCE 2000 Platform to assume operation in case of
failure of the primary device.

• Link continuity — How should the SCE 2000 respond to platform failure with regard to link

continuity? Should traffic flow continue even though the unit is not operating, or be halted
until the platform is repaired/replaced?

These issues determine three important aspects of system deployment and configuration:

• How many SCE 2000 Platforms are needed and how will they be installed?

• Physical topology of the system — The actual physical placement of the SCE 2000 in the

system.

• Topology-related configuration parameters — The correct values for each parameter must be

ascertained before configuring the system to make sure that the system will function in the
desired manner.

Chapter 3 Topology

Functionality

Number of links

Redundancy

The SCE 2000 can serve one of two general functions:

• Monitoring and Control — The SCE 2000 monitors and controls traffic flow. Decisions are

enforced by the SCE 2000 depending on the results of the monitoring functions of the SCE
2000 and the configuration of the Service Control Application for Broadband or Mobile

solution.
In order to perform control functions, the SCE 2000 must be physically installed as an inline

installation and the connection mode must be “inline”.

• Monitoring only — The SCE 2000 monitors traffic flow, but cannot control it.

Either an inline installation or an external switch installation may be used for monitoring only.
In the latter case connection mode must be “receive-only”.

The SCE 2000 can be deployed in a single FE link or in two FE links. The two-link topology may
implement load-sharing and the SCE 2000 in this case is able to process both directions of a bi­directional flow even if they split to both links.

When a high degree of reliability is desired, a second SCE 2000 Platform should be installed to
provide backup operation capabilities. The combination of two SCE 2000s guarantees
uninterrupted functioning in case of a failure of one of the platforms. The two SCE 2000s are
cascaded, so that, although all processing is performed only in the active SCE 2000, the standby
SCE 2000 is constantly updated with all the necessary information so that it can instantly take
over processing the traffic on the data links should the active SCE 2000 fail.

If only preservation of the network links is required, and uninterrupted functionality of the SCE
2000 is not required, a single SCE 2000 is sufficient.

Cisco SCE 2000 4/8xFE Installation and Configuration Guide

3-2 OL-7826-05

Chapter 3 Topology

Link Continuity

Topology Considerations

The bypass mechanism of the SCE 2000 allows traffic to continue to flow, if desired, even if the
device itself is not functioning.

Note that when the SCE 2000 is connected to the network through an external switch, a failure of
the SCE 2000 does not affect the traffic flow, as the traffic continues to flow through the external
switch.

Bypass Mechanism

The SCE 2000 includes a Network Interface Card with a bypass mechanism that is enabled upon
SCE 2000 failure. In addition, when connected in-line it can also be enabled in normal operation

to simultaneously bypass traffic flow to the other side and direct it internally for analysis. In this
case it maintains "receive-only"-like monitoring functions, when control functionality is not
required.

The bypass card supports the following four modes:

• Bypass — The bypass mechanism preserves the network link, but traffic is not processed for

monitoring or for control.

• Forwarding — This is the normal operational mode, in which the SCE 2000 processes the

traffic for monitoring and control purposes.

• Sniffing — The bypass mechanism preserves the network link, while in parallel allowing the

SCE 2000 to process the traffic for monitoring only.

• Cutoff — There is no forwarding of traffic, and the physical link is forced down (cutoff

functionality at layer 1).

Maintaining the Network Links vs Maintaining SCE 2000 Platform
Functionality

When a single SCE 2000 is deployed, the user may decide that in case of a failure, maintaining
the network link is more important than providing the SCE 2000 functionality. In this scenario,
when the SCE 2000 detects a failure that requires a reboot process for recovering, it immediately
switches to Bypass mode, allowing all traffic to bypass the SCE 2000. The SCE 2000 stays in
Bypass mode maintaining the network link, albeit without SCE 2000 processing, until the SCE
2000 fully recovers from the failure and is ready to resume normal functioning.

Alternatively, the user may decide that the SCE 2000 functionality is sufficiently crucial to
require severing the link if the SCE 2000 platform fails. In this case, when the SCE 2000 detects a
failure that requires a reboot process for recovering, it immediately switches to Cutoff mode,
stopping all traffic flow. The SCE 2000 stays in Cutoff mode, halting all traffic, until it fully
recovers from the failure and is ready to resume normal functioning. In Cutoff the physical
interface is blocked, enabling the network device connected to the SCE 2000 to sense that the link
is down.

Physical Topologies

Physical T opologies

Following are descriptions of a number of physical topologies that the SCE 2000 supports.

Single SCE 2000 T opologies

A single SCE 2000 supports both single FE link and dual FE link topologies.

Single Link: Inline Topology

Typically, the SCE 2000 is connected in a full duplex FE link between two devices (Router,
BRAS, etc.). When the SCE 2000 is installed as an inline installation, it physically resides on the
data link between the subscribers and the network.

Figure 3-1: Single SCE Platform Single Link: In-line Topology

Chapter 3 Topology

When configuring the SCE 2000, an inline installation is referred to as “inline” connection mode.

Cisco SCE 2000 4/8xFE Installation and Configuration Guide

3-4 OL-7826-05

Chapter 3 Topology

Single Link: Receive-only Topology

In this topology, an external switch resides physically on the FE link between the subscribers and
the network. The traffic passes through the external switch, which splits traffic to the SCE 2000.
The SCE 2000, therefore, only receives traffic and does not transmit.

Figure 3-2: Single SCE Platform Single Link: Receive-Only Topology

Physical Topologies

When configuring the SCE 2000, an external switch topology is referred to as “receive-only”
connection mode.

Note that in an external switch topology, the SCE 2000 only enables traffic monitoring

functionality.

When implementing receive-only topologies with a switch, the switch must support SPAN functionality
that includes separation between ingress and egress traffic and multiple SPAN-ports destinations.

OL-7826-05 3-5

Cisco SCE 2000 4/8xFE Installation and Configuration Guide

Physical Topologies

Dual link: Inline Installation

In this topology, one SCE 2000 is connected inline in two full duplex, FE links.
In case the two links are load-shared, asymmetrical routing might occur, and some of the flows

may be split, i.e. the upstream packets of the flow go on one link, and the downstream packets go
on the other link.

When installed in this topology, the SCE 2000 completely overcomes this phenomenon, and
provides its normal functionality as if asymmetrical routing were not occurring in the two links.

Figure 3-3: Single SCE Platform Dual Link Inline Topology

Chapter 3 Topology

This topology supports both monitoring and control functionality, and is referred to as “inline”
connection mode.

Cisco SCE 2000 4/8xFE Installation and Configuration Guide

3-6 OL-7826-05

Chapter 3 Topology

Dual Link: Receive-Only Topology

In this topology, one SCE 2000 is connected in receive-only mode to two full duplex, FE links
using external switchs. If the two links are load-shared, asymmetrical routing might occur, and
some of the flows may be split, i.e. the upstream packets of the flow go on one link, and the
downstream packets go on the other link.

When installed in this topology, the SCE 2000 completely overcomes this phenomenon, and
provides its normal monitoring functionality as if asymmetrical routing were not occurring in the
two links.

This installation supports monitoring functionality only, and is configured as “receive-only”
connection mode.

When implementing receive-only topologies with a switch, the switch must support SPAN functionality
that includes separation between ingress and egress traffic and multiple SPAN-ports destinations.

te

T wo Cascaded SCE 2000s For Dual Links

In this topology, two cascaded SCE 2000s are used. This allows a fail-over solution, where in case
of a failure of one SCE 2000, the functionality that the SCE 2000 provides is preserved by the
redundant platform.

Cisco SCE 2000 4/8xFE Installation and Configuration Guide

OL-7826-05 3-7

Physical Topologies

Two Cascaded SCE 2000s: Inline Topology

This topology allows both control and monitoring functionality where redundancy is required and
“inline” connection is used. The two SCE 2000s are cascaded, so the primary SCE 2000
processes the traffic of the two links, while the secondary SCE 2000 only bypasses the traffic of
its links to the primary SCE 2000 for processing, and then bypasses the processed traffic back to
the link. The two SCE 2000s also exchange keep-alive messages and subscriber state information.

In case the primary SCE 2000 fails, the two SCE 2000s switch their roles, and this way fail-over
is provided.

Figure 3-5: Two SCE Platforms: Dual Link Inline Topology

Chapter 3 Topology

This fail-over solution preserves the SCE 2000 functionality and the network link:

• The two SCE 2000s are simultaneously aware of the subscriber contexts, and subscriber states

are constantly exchanged between them, such that if the primary SCE 2000 fails, the
secondary can take over with minimum state loss.

• When one SCE 2000 fails (depending on the type of failure) its link traffic is still bypassed to

the functioning SCE 2000 and processed there, so the traffic processing continues for both the
links.

• The bypass of the traffic through the failed SCE 2000 is configurable, and the user may

choose to always cutoff the line that goes through the failed SCE 2000. In this case network
redundancy protocols like HSRP are responsible for identifying the line cutoff and switching
all the traffic to go through the functioning SCE 2000.

T opology-Related Parameters

Refer to the following sections to determine the correct values for all topology-related parameters
before beginning run the initial setup of the SCE 2000.

Cisco SCE 2000 4/8xFE Installation and Configuration Guide

Chapter 3 Topology

SCE 2000 Configuration

There are four topology-related parameters:

• Connection mode — Can be any one of the following, depending on the physical installation

• Physically-connected-links — In cascaded configurations, this parameter defines the number

• Priority — This parameter defines which is the primary SCE 2000 (Refer to Priority (on

Physical Topologies

of the SCE 2000 (Refer to Connection Mode Parameter (on page 3-9)):

• Inline — single SCE 2000 inline

• Receive-only — single SCE 2000 receive-only

• Inline-cascade — two SCE 2000s inline

• Receive-only-cascade — two SCE 2000s receive-only

of the link connected to this SCE 2000 (Refer to Physically Connected Links Parameter (on

page 3-10)).

It is applicable only in a cascade topology.

page 3-10)).

It is applicable only in a cascade topology.

• On-failure — This parameter determines whether the system cuts the traffic or bypasses it

when the SCE 2000 either has failed or is booting. It is not applicable to receive-only

topologies (Refer to On-Failure Mode Parameter (on page 3-10)).
Any of these parameters may be configured via either the setup command or the

connection-mode command.

Connection Mode Parameter

The connection mode parameter refers directly to the physical topology in which the SCE 2000 is
installed. The connection mode depends on two factors:

• Inline/Receive-only:

• Inline — The SCE 2000 resides on the data link between the subscriber side and the

network side, thus both receiving and transmitting packets.

• Receive-only — The SCE 2000 does not reside physically on the data link. Data is

forwarded to the SCE 2000 via an external switch. The SCE 2000 itself receives only and
does not transmit.

• Cascade — Indicates a two SCE 2000 topology where the SCE 2000s are connected via the

cascade ports.
The connection mode parameter is determined by the physical deployment of the SCE 2000, as

follows:

• Single SCE 2000 inline installation = “Inline” connection mode.

• Single SCE 2000 external switch installation = “Receive-only” connection mode.

• Two SCE 2000 inline installation = “Inline-cascade” connection mode.

• Two SCE 2000 external switch installation = “Receive-only-cascade” connection mode.

OL-7826-05 3-9

Cisco SCE 2000 4/8xFE Installation and Configuration Guide

Physical Topologies

Physically Connected Links Parameter

If the system consists of more than one device, this parameter defines which link is connected to
this SCE 2000. Currently the system supports a maximum of two links, which are designated link
0 and link 1.

Priority

In a cascade topology, the user must define the priority of each SCE 2000.

• Primary — The Primary SCE 2000 is active by default

• Secondary — The Secondary SCE 2000 is the default standby.

Note that these defaults apply only when both devices are started together. However, if the
primary SCE 2000 fails and then recovers, it will not revert to active status, but remains in
standby status, while the secondary device remains active.

On-Failure Mode Parameter

As described in the section The Bypass Mechanism, the bypass card supports four different
modes. The following two modes are possible when the SCE 2000 is not operational due to
platform failure or boot:

Chapter 3 Topology

• Bypass — The external switch forwards traffic with no intervention of the control application

running in the SCE 2000 platform, but monitoring functions continue uninterrupted.

• Cutoff — There is no forwarding of traffic. The link is forced down, resulting in traffic cutoff

at Layer1.

The Forwarding mode enables control of traffic flow and is not compatible with the non­operational status.

In a single SCE 2000 topology, the value of this parameter is determined by whether or not the
link can be completely cut when the SCE 2000 fails, or whether traffic flow should continue
across the link in spite of platform failure.

• Cutoff mode is required for the following:

• Redundant inline topology.

• Non-redundant inline topology if value-added services are crucial and are more important

than maintaining connectivity.

• Bypass mode is required for the following:

• Non-redundant inline topology if connectivity is crucial.

Chapter 4 Installation and Maintenance

Site Requirement Guidelines

The environmental monitoring functionality in the SCE 2000 protects the system and components
from potential damage from over-voltage and over-temperature conditions. To ensure normal
operation and to avoid unnecessary maintenance, plan your site configuration and prepare your
site before installation. After installation, make sure the site maintains an ambient temperature of
41°F to 104°F (5°C to 40°C) with short term temperatures ranging from 23°F to 131°F (–5°C to
55°C), and keep the area around the SCE 2000 chassis free from dust.

Planning a proper location for the SCE 2000 and the layout of your equipment rack or wiring
closet is essential for successful system operation. Equipment placed too close together or
inadequately ventilated can cause system over-heating. In addition, chassis panels made
inaccessible by poor equipment placement can make system maintenance difficult.

Airflow

Figure 4-2: Airflow Through the SCE Platform

Preparing to Install the SCE 2000 Platform

When you plan the location and layout of your equipment rack or wiring closet you need to
consider how air flows though your system. The SCE 2000 draws cooling air in through the
intake vents on the left side of the chassis, moves the air across the internal components, and out
through the right side and rear panel of the chassis. The above figure illustrates the airflow

Installing the SCE 2000 Platform

The SCE 2000 operates as either a tabletop or a rack-mounted unit. A rack-mounting kit is
included with the SCE 2000 when it is shipped from the factory. The kit provides the hardware
needed (see SCE 2000 Component List) to mount the SCE 2000 in either of two types of standard
19-inch equipment rack:

• 19-inch rack with only two posts in the front — Use the supporting brackets included in the

kit

• 19-inch rack with four posts, two in the front and two in the back — Use the crossrail

supports included in the kit

If you are not rack-mounting your SCE 2000, place it on a sturdy tabletop or workbench. A rubber
feet kit is included for tabletop installations.

This section provides instructions for the physical installation of the SCE 2000 platform,
including how to install the SCE 2000 in a rack, how to install the SCE 2000 on a tabletop or

Installation Precautions

The router should already be in the area where you will install it, and your installation location
should already be determined. If not, see Site Requirement Guidelines (on page 4-3) and the Site
Preparation and Safety Guide.

When installing the SCE 2000, please observe the following conditions:

• Allow at least 2 inches (5 cm) of clearance at its left and right sides for airflow clearance from

the inlet and exhaust vents, and that no exhaust air from other equipment is drawn into the

SCE 2000. For descriptions and illustrations regarding airflow, see Airflow (on page 4-3).

• Do not place the SCE 2000 on the floor during installation. Dust that accumulates on the floor

is drawn into the interior of the SCE 2000 by the cooling fans. Excessive dust inside the SCE

2000 can cause over-temperature conditions and component failures.

• Allow at least 5 inches (12.7 cm) of clearance at the front and rear of the SCE 2000 for

installing and rudimentary maintenance for accessing network cables or equipment.

• Ensure that the SCE 2000 will receive adequate ventilation. Do not install the SCE 2000 in an

enclosed cabinet where ventilation is inadequate!

• Provide an adequate chassis Ground (earth) connection for the SCE 2000 (see Attaching a

Chassis Ground Connection (on page 4-10) for instructions).

This completes the procedure for installing the SCE 2000 chassis. Proceed to the next section,
Connecting to the Power Supply, to continue the installation.

Power Supply Overview

Power Supply Overview

The SCE 2000 is available in two power options:

• Dual line feed AC power — SCE 2000 is shipped with two appropriate AC power supply

cords.

• Dual line feed DC power — requires appropriate cables (hex or loop connectors) (see

Reconnecting DC-Input Power Supply Unit (on page 4-18)).
The dual power supply units supply hot-swappable, redundant power. Redundant power is useful

as a failover; if a situation occurs where one power supply is down (for instance, a power supply
fails or a new power supply needs to be installed), the SCE 2000 can continue to run properly
using the other power supply.

Each power supply has fans that cool the power supply unit. These fans also help to cool the
internal components of the SCE 2000, as they direct the air flow to the outside through vents in
the rear of the power supply unit.

The faceplates of both power supplies have a handle, an on/off switch, and one captive installation
screw. An AC-input power receptacle is available on the AC-input power supply and a DC-input
terminal block is available on the DC-input power supply.

Note that the power supply units are asymmetrical, with a screw in only one corner of the unit.
Therefore, both power supply units can be fastened only if both units are inserted in the proper
orientation. This also prevents the accidental installation of one DC unit and one AC unit. (Refer
to the following figures).

LEDs

The following LEDs are used to monitor the functioning of the power supply units:

• On the power supply unit (both AC-input and DC-input):

• IN LED (green)

• OK LED (green)

• On the Front Panel (on page 2-1):

• Power LED — There are two Power LEDs on the front panel (Power A and Power B), one

LED corresponding to each power supply unit

On both the AC-input and DC-input power supplies, the IN LED iis used to monitor the voltages
received by the platform from the power source. If the input voltages are within normal operating
ranges, the green IN LED is illuminated. If the input voltages are above or below normal ranges,
the IN LED is not illuminated.

On both the AC-input and DC-input power supplies, the OK LED is used to monitor the power
supply DC output voltages used to power the platform. The normal operating ranges for the 12
VDC output voltage is between 11.9V and 12.1V. If the output voltages are within normal
operating ranges, the green OK LED is illuminated. If the 12 VDC output voltages are above
(more than 12.1V) or below (less than 11.9V) normal ranges, the OK LED is not illuminated.

The Power A and Power B LEDs on the front panel indicate whether the corresponding power
supply unit is functioning normally.

Connecting the Local Console

Setting Up the Local Console

This section provides instructions for setting up your local terminal at your workstation, to enable
you to perform the initial system configuration of the SCE 2000 system using the setup utility.

Figure 5-1: Connecting to the Local Console

Make sure that the terminal configuration is as follows:

• 9600 baud

• 8 data bits

• No Parity

• 1 stop bits

• No flow control

The above SCE 2000 port parameters are fixed and are not configurable.
To set up the local console, complete the following steps:

Step 1 Plug the RS-232 serial cable provided with the SCE 2000 into the CON port on the front panel of

the SCE 2000.
Make sure that you push on the RJ-45 connector (attached to the RS-232 serial cable) until you

hear a “click”, which indicates that the connector is fully inserted and secured in the receptacle.
Gently pull on the plug to confirm whether the plug is locked into the socket.

Step 2 Connect the other end of the serial cable (with an attached DB-9 connector) to the VT100

compatible local (serial) terminal.

Step 3 Make sure the local terminal is configured as a VT-100 terminal, according to the fixed SCE 2000

CON port parameters.

Step 4 Press Enter several times until the Cisco logo appears on the local terminal and the setup

configuration dialog is entered.

Chapter 5 Connecting the Management Interfaces and Performing Initial System Configuration

Initial System Configuration

Upon initial connection to the local terminal, as described above, 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.

With the exception of 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.

The following table lists all the parameters included in the initial configuration. It is
recommended that you obtain values for any parameters that you will configure at this time before
beginning the setup.

Enter RDR-formatter destination’s IP address: 10.1.1.230
Enter RDR-formatter destination’s TCP port number: 33000

Step 7: Configuring Access Control Lists (ACLs)

The SCE 2000 can be configured with Access Control Lists (ACLs), which are used to permit or
deny incoming connections on any of the management interfaces.

Note

ACL #0 is a pre-defined list that permits access to all IP addresses.

Configuration of access control lists is done in two stages:

Step 1 Create the access control lists.

You may create 99 ACLs with a maximum of 20 entries per list. Each entry consists of an IP
address, and an indication of whether access is permitted or denied to this IP address.

Step 2 Assign the ACLs to the appropriate management interface. (See Step 9: Configuring the

Topology-Dependent Parameters (on page 5-19).)

The dialog permits you to skip the creation/editing of the ACLs and go directly to assigning ACLs
to the management interfaces.

Cisco SCE 2000 4/8xFE Installation and Configuration Guide

5-12 OL-7826-05

Chapter 5 Connecting the Management Interfaces and Performing Initial System Configuration

Initial System Configuration

Entry Formats

Each ACL may permit/deny access to any IP address, one or more ranges of IP addresses, or one
or more individual IP address. Three entry formats are available to support these options:

• Any IP address — Type the word “any”. Any IP address will be permitted or denied access.

• Range of IP addresses — Type the beginning IP address in the desired range, then enter the

wildcard bits that define the range.
This wildcard functions like a reverse mask, in that all “1” bits in the wildcard indicate the

corresponding bit in the IP address should be ignored. All other bits must match the
corresponding bit in the specified IP address. Refer to the table below for examples.

Each range of IP addresses can be configured to be permitted or denied access.

• Individual IP address — Type the desired IP address, then enter the wildcard bits 0.0.0.0.

Each individual IP address can be configured to be permitted or denied access.

Table 5-2 IP address/Wildcard bit examples

Initial IP address Wildcard bits Range

10.1.1.0 0.0.0.255 10.1.1.0–10.1.1.255

10.1.1.0 0.0.0.63 10.1.1.0–10.1.1.63

10.1.1.0 0.0.0.0 10.1.1.0 (individual entry)

Order of Entries

The order of the entries in the list is important. The entries in the list are tested sequentially, and
the action is determined by the first entry that matches the connecting IP address. Therefore, when
the entry “any” appears in an Access Control List, all succeeding entries are irrelevant.

Consider two hypothetical ACLs containing the same entries in a different order.
The following list would permit access to all IP addresses, including 10.1.1.0:

permit any
deny 10.1.1.0

Note that the above list could not actually be created using the setup utility, since after the “any”
entry, no other entries could be added to the list.

The following list will deny access to IP address 10.1.1.0, but permit access to all others:

deny 10.1.1.0
permit any

If no entry in the assigned Access Control List matches the connection, or if the Access Control
List is empty, the default action is deny.

To create the access control lists, complete the following steps:

Step 1 Enter the Access Control Lists configuration menu.

OL-7826-05 5-13

Cisco SCE 2000 4/8xFE Installation and Configuration Guide

Initial System Configuration

Type y and press Enter.
The Access Control Lists configuration dialog begins.

Step 2 You have the option of creating or modifying Access Control Lists, or skipping this section and

proceeding directly to assign the existing ACLs to the desired management interfaces.

If you choose not to create or edit Access Control Lists, skip to Step 9: Configuring the Topology-
Dependent Parameters (on page 5-19).

Step 3 Type the number of the Access Control List to be configured (1 through 99) and press Enter.

Note that there is no default for this parameter.

You are now prompted to assign the desired ACLs to restrict IP and Telnet access.

Step 9 Restrict IP access to the SCE 2000 by assigning the appropriate ACL.

Type the number of the ACL to be assigned to IP access and press Enter.

Step 10 Restrict Telnet access to the SCE 2000 by assigning the appropriate ACL.

To accept the default ACL, press Enter.

EXAMPLE 1:

This example illustrates a common access control scenario. Let us assume the following:

• We want to permit every station to access the SCE platform on the management port (e.g.

ping, SNMP polling etc.).

• We want to restrict Telnet access to only a few permitted stations.

We therefore need to create two access control lists:

• For general IP access — permit access to all IP addresses.

• For Telnet — permit access to the specified IP address, and deny to all others.

ACL #1 = permit any IP address. Assign to IP access.
ACL #2 = permit access to 10.1.1.0, 10.10.10.1, deny to all others. Assign to Telnet access.

Step 8: Configuring SNMP

Managing the SCE 2000 is possible also via a Network Management System (NMS) that supports
SNMP. By default, SNMP is disabled on the SCE 2000.

To enable SNMP management you must configure the following basic SNMP parameters:

• SNMP traps status and managers.

• Community strings (where an SNMP community string is a text string that acts like a

password to permit access to the SNMP agent on the SCE 2000).

Step 9: Configuring the T opology-Dependent Parameters

The topology configuration menu is a series of guided questions relating to the deployment of the
SCE 2000 in the network and its mode of operation. Values for the parameters are configured
based on the user answers.

The correct value for each parameter must be ascertained before configuring the system to make
sure that the system will function in the desired manner. (See Topology (on page 3-1) for a
comprehensive discussion of topology and the related parameters.)

Initial System Configuration

Note

Values may not be requested for all topology-dependent parameters, as certain parameters do not apply
to all topologies.

There are six topology-related parameters:

• Connection mode — Can be either of the following, depending on the physical installation of

the SCE 2000.

• Inline

• Receive-only

• Type of deployment — Can be one of the following, depending on the actual deployment:

• Single-SCE Platform — a single SCE 2000 is deployed on one or two FE links

• Cascade — two cascaded SCE 2000s are deployed on two FE links, working as a fully

redundant solution.

• Physically connected link (cascade topology only) — In a cascade topology, the user must

assign an index to each of the links. This index is used to identify the services per link.
In a single-SCE platform deployment, the indices of the links cannot be changed by the user

and are:

• link-0 — the link connected to ports 1 and 2

• link-1 — the link connected to ports 3 and 4

In a cascade deployment, the user must define which link is connected to which SCE 2000.
The index must be different for each SCE 2000. In this case the user can choose one of the
following:

• Link-0 — the link connected to this SCE 2000 is identified as 0.

• Link-1 — the link connected to this SCE 2000 is identified as 1.

• Priority (cascade topology only) — In a cascade topology, this parameter determines which

SCE 2000 is chosen as the active SCE 2000 in the “active election” procedure. This decision
is taken only when both SCE 2000s are starting up together. If there is one working SCE 2000
and the other is just starting up, then the working one will automatically be chosen as active
and the other one as standby. This parameter can be set to one of the following:

• Primary

• Secondary

OL-7826-05 5-19

Chapter 5 Connecting the Management Interfaces and Performing Initial System Configuration

Initial System Configuration

• On-Failure behavior — Determines the behavior of the SCE 2000 upon failure, or reboot.

One of the following link modes may be chosen for the SCE 2000 in the cases of failure or
reboot.:

• Bypass — traffic is bypassed using the internal bypass card.

• Cutoff — the link is forced down.

• Admin status after abnormal reboot — This parameter determines whether the SCE 2000

returns to full operational mode after abnormal (not user-requested) boot, or stays in non­operational mode, in which the SCE 2000 behaves as in failure mode. This parameter can be
set to one of the following:

• Operational

• Non-operational

The procedure described below is a presentation of all the questions in the topology configuration.
In actual practice, all questions may not be presented for a particular configuration, depending on
the topology deployed.

Connecting the Management Interface

The SCE platform is equipped with two RJ-45 management (MNG) ports. These ports provide
access from a remote management console to the SCE platform via a LAN. The two management
ports provide the possibility for a redundant management interface, thus ensuring management
access to the SCE platform even if there is a failure in one of the management links.

If only one management port is used, the desired port is simply connected directly to the LAN. If
both management ports are used, they must both be connected to the management console via a
switch. In this way, the IP address of the MNG port is always the same, regardless of which
physical port is currently active.

The procedures for cabling the management port and testing connectivity between the SCE 2000
and the remote management host are explained in the following sections:

• Cabling the Management Port (on page 5-26)

• Verifying Management Interface Connectivity (on page 5-26)

OL-7826-05 5-25

Cisco SCE 2000 4/8xFE Installation and Configuration Guide

Chapter 5 Connecting the Management Interfaces and Performing Initial System Configuration

Connecting the Management Interface

Cabling the Management Port

The SCE 2000 has two management ports, labeled Mng1 and Mng 2.
To cable the management port, complete the following steps:

Step 1 Take the Ethernet cable provided (with attached RJ-45 connector) and plug it into the desired

MNG port on the front panel of the SCE 2000, as shown in the following figure.

Figure 5-2: Cabling the Management Port

Step 2 Connect the other end of the Ethernet cable into your management network.

• If only one management port is used — connect the port directly to the LAN.

• If both management ports are used — connect both ports to the LAN via a switch.

Make sure that you push on the RJ-45 connector attached to the cable until you hear a click,
which indicates that the connector is fully inserted and secured in the receptacle. Gently pull on
the plug to confirm whether the plug is locked into the socket.

If the Link LED on the SCE 2000 management port does not light, try removing the cable and
reinserting it firmly into the module socket. To disconnect the plug from the socket, press down
on the raised portion on top of the plug, releasing the latch. You should hear an audible click
indicating the latch has released. Carefully pull the plug out of the socket.

If the management port Link LED on the SCE 2000 still does not light, verify that the cable is
connected correctly to the appropriate network element on its second end.

V erifying Management Interface Connectivity

If the SCE 2000 platform has been powered up, test now to verify that connectivity has been
established between the SCE 2000 and the remote management host. If the SCE 2000 platform is
not powered up, perform this step after starting the SCE 2000 platform.

To verify that connectivity has been established between the SCE 2000 and the remote
management host, complete the following steps:

Step 1 After you connect the cable to the appropriate Mng port and to your network, check the relevant

Mng port LEDS.
There are two Mng LEDs: Link/Active, and 10/100/1000 (refer to Front Panel (on page 2-1)).

Cisco SCE 2000 4/8xFE Installation and Configuration Guide

Chapter 5 Connecting the Management Interfaces and Performing Initial System Configuration

Connecting the Management Interface

At this point, check that the Link/Active LED is green.
The state of the 10/100/1000 LED will depend on the Ethernet network settings.
Green indicates 100 Mbps and ‘Off’ indicates 10 Mbps.

Step 2 Test connectivity. From the host that you intend to use for remote management, ping to the SCE

2000 by typing ping and the SCE 2000 IP address, and pressing Enter (see the example, below).

Note

Please note that only step 2 above, is performed from the remote management host (Mng port
connection).

This verifies that an active connection exists between the specified station and the management
port.

The ping program sends an echo request packet to an IP address and then awaits a reply. Ping
output can help you evaluate path-to-host reliability, delays over the path, and whether the host
can be reached or is functioning.

This completes the procedures for connecting the management interfaces and for initial
configuration of the SCE 2000 platform. Proceed to the next chapter for a description of the
procedures for cabling the Fast Ethernet ports f and for configuring Fast Ethernet (FE) interface
parameters.

In the inline topology, the SCE 2000 resides physically on the FE (Fast Ethernet) link between the
subscribers, which are usually connected through either a BRAS (in DSL access), a PDSN (in
wireless access), a CMTS (in the Cable access), or a switch or router aggregator (in other
topologies), and the network, where the SCE 2000 usually connects to a router or layer 3 switch
network element.

Chapter 6 Cabling the Line Ports and Completing the Installation

In the single link inline topology, either the first FE link (FE-1 SUB/NET) of the SCE 2000 or the
second FE link (FE-2 SUB/NET) can be used, as illustrated in the diagram above. The remaining
ports are unused.

The port labeled "SUB" is used for connecting to the network element that is deployed on the
subscriber side of the SCE 2000, while port labeled "NET" is used for connecting to the network
element that is deployed on the network side of the SCE 2000.

Single Link: Receive-only Topology

In this topology, an external switch resides physically on the FE link that the SCE 2000 should
monitor. The traffic passes through the external switch, which splits traffic to the SCE 2000.

The external switch should be configured with two-port replication configurations, one for
upstream and one for downstream traffic on the FE link. The replicated ports should then be
connected to the appropriate SCE 2000 ports.

Connecting the line ports to the network

Note

When implementing receive-only topologies with a switch, the switch must support SPAN functionality
that includes separation between ingress and egress traffic and multiple SPAN-ports destinations.

Figure 6-2: Cabling Diagram for Single SCE Platform Single Link Receive-only T opology

The single link receive-only topology cabling is similar to that for single link inline, in that either
the first FE link (FE-1 SUB/NET) of the SCE 2000 or the second FE link (FE-2 SUB/NET) can
be used, as illustrated in the diagram above. However, in the receive-only topology, the SCE 2000
is connected to the external switch rather than being directly connected to the FE link.

The port labeled "SUB" is used for connecting to the network element that is deployed on the
subscriber side of the SCE 2000 while port labeled "NET" is used for connecting to the network
element that is deployed on the network side of the SCE 2000. The remaining ports are unused.

Dual Link: Single SCE 2000 Topologies

In this topology, one SCE 2000 is connected to two full duplex, FE links. The SCE 2000 may be
either inline, to support both monitoring and traffic control functionality, or receive-only for
traffic monitoring functionality only.

When one SCE 2000 supports two links, the first pair of ports (FE-1 SUB/NET) is connected to
one link, while the second pair of ports (FE-2 SUB/NET) is connected to the second link as
follows;

• FE-1 SUB: Link 1, Subscriber side

• FE-1 NET: Link 1, Network side

• FE-2 SUB: Link 2, Subscriber side

• FE-2 NET: Link 2, Network side

The following diagram illustrates the connections for dual links, with a single SCE 2000 deployed
for both inline and receive-only topologies.

For inline topologies, the SCE 2000 is directly connected to the two FE links, using the FE-1 and
FE-2 ports as described above.

Chapter 6 Cabling the Line Ports and Completing the Installation

For receive-only topologies, the SCE 2000 is connected to the external switch, which should be
configured with two-port replication configurations, one for upstream and one for downstream
traffic on the FE link. The replicated ports should then be connected to the SCE 2000 using the
FE-1 and FE-2 ports as described above.

Figure 6-3: Cabling Diagram: Dual Link One SCE Platform Inline

Dual Link: Two SCE 2000s Topology

In this topology, two SCE 2000s are connected to two full duplex, FE links, providing full
redundancy through cascading the two SCE 2000s. The SCE 2000s may be either inline, to
support both monitoring and traffic control functionality, or receive-only for traffic monitoring
functionality only .

When two SCE 2000s are used, the first pair of ports (FE-1 SUB/NET) in each SCE 2000 is
connected to the links, while the second pair of ports (FE-2 SUB/NET) become the cascade ports
used for communicating between the two SCE 2000s as follows:

SCE 2000 #1

• FE-1 SUB: Link 1, Subscribers side

• FE-1 NET: Link 1, Network side

• FE-2 SUB: Cascade, connect to FE-2 NET in SCE 2000 #2

Chapter 6 Cabling the Line Ports and Completing the Installation

• FE-2 NET: Cascade, connect to FE-2 SUB in SCE 2000 #2

SCE 2000 #2

• FE-1 SUB: Link 2, Subscribers side

• FE-1 NET: Link 2, Network side

• FE-2 SUB: Cascade, connect to FE-2 NET in SCE 2000 #1

Connecting the line ports to the network

• FE-2 NET: Cascade, connect to FE-2 SUB in SCE 2000 #1

Note

Cascade ports must be connected directly in Layer 1 (dark fibers).

Inline topologies can both Receive and Transmit to the SCE 2000. Cascade ports always require
both Receive and Transmit to be connected.

The following diagram illustrates the connections for a dual link, two SCE 2000 inline topology
For inline topologies, the SCE 2000 is directly connected to the two FE links, using the FE-1

ports on the two SCE 2000s, while the FE-2 ports on both units are used as the cascade ports, as
described above.

For receive-only topologies, the SCE 2000 is connected to the external switch, which should be
configured with four port replication configurations, one for upstream and one for downstream
traffic for each FE link. (Alternatively, two external switchs may be used, one for each link, with
each configured with two-port replication configurations.) The replicated ports should then be
connected to the SCE 2000s using the FE-1 ports as described above. The FE-2 ports on each

Note

SCE 2000 are used as the cascade ports.

When implementing receive-only topologies with a switch, the switch must support SPAN functionality
that includes separation between ingress and egress traffic and multiple SPAN-ports destinations.

Cabling the FE Line Port

Ports FE-3 and FE-4 currently have no software support.

Chapter 6 Cabling the Line Ports and Completing the Installation

To cable the SCE 2000 line port, complete the following steps:

Step 1 Take the appropriate fiber optic cable and plug it into the appropriate RJ-45 FE port on the front

panel of the SCE 2000.
Make sure to push on the connector until you hear a click, which indicates that the connector is

fully inserted and secured in the receptacle. Always make sure that you insert the connector
completely into the socket.

Figure 6-5: Cabling the FE Interface

Step 2 Verify that the link LED is green.

Connecting the line ports to the network

If the link LED does not light, try removing the network cable plug and reinserting it firmly into
the module socket.

T esting Connectivity: Examining Link LEDs and Counters

If the SCE 2000 platform has been powered up, test now to verify that connectivity has been
established on all links. If the SCE 2000 platform is not powered up, perform this step after
starting the SCE 2000 platform.

Examining the Link LEDs

The Link LED must be green in order to verify that an active connection exists.
The Active LED (if flashing green) indicates that traffic is being received and/or transmitted by

the SCE 2000.
In receive-only topologies, the Active LED indicates that packets are being received. In this

mode, there is no transmission of packets.

Connecting the line ports to the network

Viewing the Counters to see that the Network Traffic is Reaching
the Device

In an inline topology, you can monitor traffic via the platform counters for both the Rx and Tx
connections. The counters increase, together with the increased number of packets that flow
through the SCE 2000 for both Rx and Tx.

However, in external switch topologies, the counters for the Tx do not increment, that is, Tx does
not have a function in monitoring traffic, as it is disconnected.

To view the Fast Ethernet port status, complete the following steps:

Step 1 At the SCE 2000# prompt, type show interface FastEthernet 0/interface-number.

This displays the port link and auto-negotiation status.

EXAMPLE:

Chapter 6 Cabling the Line Ports and Completing the Installation

The following example displays a system response.

SCE 2000#show interface FastEthernet 0/1
Auto negotiation configured: Enabled
Actual Status:
Link is on
Auto negotiation: Enabled
Bandwidth: 100000Kbps
Burst-size: 50000bytes

Auto-negotiation for an inline topology may be enabled or disabled. For receive-only topologies
using an external switch, auto-negotiation must be disabled.

To view the FastEthernet counters, complete the following steps:

Step 1 At the SCE 2000# prompt, type show interface FastEthernet 0/interface-number

counters.

This displays the FastEthernet counters. This command enables you to verify that traffic is taking
place. You can see that the counters increase, together with the increased number of packets that
flow through the SCE 2000.

Again, in inline topology, both the Rx and Tx counters apply as traffic monitors. For receive-only
topologies, using an external switch, only the Rx counters apply.

EXAMPLE:

6-8 OL-7826-05

The following example shows the counters of the first Fast Ethernet interface.

SCE 2000#show interface FastEthernet 0/1 counters
In total octets: 100
In good unicast packets: 90
In good multicast packets: 0
In good broadcast packets: 10

Chapter 6 Cabling the Line Ports and Completing the Installation

In packets discarded: 0
In packets with CRC/Alignment error: 0
In undersized packets: 0
In oversized packets: 0
Out total octets: 93*2^32+1022342538
Out unicast packets: 858086051
Out non unicast packets: 0
Out packets discarded: 0

You are now ready to continue to the next stage, loading and activating an Service Control
application.

Installing a Cascaded System

This section outlines the installation procedures for a redundant solution with two cascaded SCE
2000s. Refer to the Cisco Service Control Engine (SCE) CLI Command Reference for details of

the CLI commands.

Installing a Cascaded System

Warning

When working with two SCE 2000s with split-flow and redundancy, it is extremely important to follow
this installation procedure.

To install a cascaded system, complete the following steps:

Step 1 Install both SCE 2000s, power them up, and perform the initial system configuration. (See

Installation and Maintenance (on page 4-1) and Connecting the Management Interfaces and
Performing Initial System Configuration (on page 5-1).)

Step 2 Connect both SCE 2000s to the management station.(See Connecting the Management Interface

(on page 5-25))

Step 3 Connect the cascade ports. The cascade ports must be connected directly in Layer 1 (dark fibers),

not through switches. (See Dual Link: Two SCE 2000s T opology (on page 6-4).)

Step 4 Set topology configurations for each SCE 2000 via the connection-mode options. (See Topology-

Related Parameters for Redundant Topologies (on page 6-10).)

Step 5 Make sure that theSCE 2000s have synchronized and active SCE 2000 was elected.

Use the show interface linecard 0 connection-mode command.

Step 6 If you want to start with bypass/sniffing, change the link mode to your required mode in both

SCE 2000s on both links. The bypass mode will be applied only to the active SCE 2000. (See

Link Mode (on page 6-11).)

Step 7 Make sure that the link mode is as you required. (See Monitoring the System (on page 6-12).)

Use the show interface linecard 0 link mode command.

Step 8 Connect the traffic port of SCE 2000 #1. This will cause a momentary down time until the

network elements from both sides of the SCE 2000 auto-negotiate with it and start working (when
working inline). (See Dual Link: Two SCE 2000s Topology (on page 6-4).)

OL-7826-05 6-9

Cisco SCE 2000 4/8xFE Installation and Configuration Guide

Installing a Cascaded System

Step 9 Connect the traffic port of SCE 2000 #2, this will cause a momentary down time until the network

elements from both sides of the SCE 2000 auto-negotiate with it and starts working (when
working inline). (See Dual Link: Two SCE 2000s Topology (on page 6-4).)

Step 10 When full control is needed, change the link mode on both SCE 2000s on both links to

‘forwarding’. It is recommended to first configure the active SCE 2000 and then the standby. (See
Link Mode (on page 6-11).)

Step 11 You can now start working with the Subscriber Manager.

CLI Commands for Cascaded Systems

This section presents CLI commands relevant to the configuration and monitoring of a redundant
system.

Use the following commands to configure and monitor a redundant system:

• connection-mode

• [no] force failure-condition

Chapter 6 Cabling the Line Ports and Completing the Installation

• Show interface linecard 'number' connection-mode

• Show interface linecard 'number' physically-connected links

Topology-Related Parameters for Redundant Topologies

All four of the topology-related parameters are required when configuring a redundant topology.

• Connection mode — Redundancy is achieved by cascading two SCE platforms. Therefore

the connection mode for both SCE platforms may be either:

• Inline-cascade

• Receive-only-cascade

• Physically-connected-links — For each of the cascaded SCE platforms, this parameter

defines the number of the link (Link 0 or Link 1) connected to this SCE platform.

• Priority — For each of the cascaded SCE platforms, this parameter defines whether it is the

primary or secondary device.

• On-failure — For each of the cascaded SCE platforms, this parameter determines whether the

system cuts the traffic or bypasses it when the SCE platform either has failed or is booting.

Configuring the Connection Mode

Use the following command to configure the connection mode, including the following
parameters:

• inline/receive only

• physically connected links

• behavior upon failure of the SCE platform

• primary/secondary

Cisco SCE 2000 4/8xFE Installation and Configuration Guide

6-10 OL-7826-05

Chapter 6 Cabling the Line Ports and Completing the Installation

To configure the connection mode, use the following command:

From the SCE 2000(config if)# prompt, type connection-mode inline-

cascade/receive-only-cascade [physically-connected-links {link­0/link-1}] [priority {primary/secondary}] [on-failure

{bypass/cutoff}] and press Enter.

EXAMPLE 1

Use the following command to configure the primary SCE platform in a two-SCE platform inline
topology. Link 1 is connected to this SCE platform and the behavior of the SCE platform if a
failure occurs is bypass.

SCE 2000(config if)# connection-mode inline-cascade physically-connected­links link-1 priority primary on-failure bypass

EXAMPLE 2

Use the following command to configure the SCE platform that might be cascaded with the SCE
platform in Example 1. This SCE platform would have to be the secondary SCE platform, and
Link 0 would be connected to this SCE platform, since Link 1 was connected to the primary. The
connection mode would be the same as the first, and the behavior of the SCE platform if a failure
occurs is also bypass.

SCE 2000(config if)# connection-mode inline-cascade physically-connected­links link-0 priority secondary on-failure bypass

Installing a Cascaded System

Link Mode

The SCE platform has an internal hardware card used to maintain the links even when the SCE
platform fails. This hardware card has four possible modes of operation:

• bypass

• forwarding

• cutoff

• sniffing

Normally, the link mode is selected by the SCE platform software according to the configured
connection-mode. However, the link-mode command can be used to enforce a specific desired
mode. This may be useful when debugging the network, or in cases where we would like the SCE
platform just to forward the traffic. (Note that this is only relevant to inline topologies even
though the configuration is available also when in receive-only mode.)

The following link mode options are available:

• Forwarding — forwards traffic on the specified link to the SCE platform for processing.

• Bypass — stops all forwarding of traffic on the specified link to the SCE platform. Traffic

still flows on the link, but is not processed in any way by the SCE platform.
This does not affect the redundancy states.

OL-7826-05 6-11

Cisco SCE 2000 4/8xFE Installation and Configuration Guide

Installing a Cascaded System

• Sniffing — allows the SCE platform to forward traffic on the specified link through the

bypass mechanism while still analyzing the traffic passively.
Sniffing is permitted to be configured for all links, only (use the all-links option).

• Cutoff — completely cuts off flow of traffic through the specified link.

Note the following recommendations and restrictions:

• Since the SCE 1000 platform has only one link, the link is not specified.

• Since the SCE 2000 platforms have more than one link, it is required to specify the link. The

link designations are different for the GBE and FE platforms, as follows:

• SCE 2000 4xGBE — GBE1-GBE2/GBE3-GBE4

• SCE 2000 4/8xFE — LINK1/LINK2

• Use the 'all-links' option to configure the link mode for all links (SCE 2000 platforms

only).

• It is recommended that both links be configured together. Use the all-links option.

• Link mode is relevant only to inline topologies.

Chapter 6 Cabling the Line Ports and Completing the Installation

• It is recommended that in cascaded topologies, both SCE platforms be configured for the

same link mode, otherwise the service will be unpredictable.

• Sniffing can only be configured for all links, therefore, to configure sniffing, the all-links

option is required, not just recommended.

• The default link mode is forwarding. When other link modes are selected, active service

control is not available and any service control configuration will not be applicable.

To set the link mode, use the following command:

From the SCE 2000 (config if)# prompt, type link-mode [<link>|all-links]
[forwarding|bypass|sniffing|cutoff] and press Enter.

Monitoring the System

Use the following commands to view the current connection mode and link mode parameters.
To view the current connection mode, use the following command:

From the SCE 2000# prompt, type show interface linecard 0 connection-mode
and press

Enter.

Loading and Activating a Service Control Application

The SCE 2000 platform provides the basic functionalities of Service Control analysis and
enforcement. A Service Control solution requires that a Service Control application be loaded into
the platform, to take advantage of the unique SCE platform capabilities.

Loading and activating an application includes the following stages:

• Downloading the application provided as an SLI file to the SCE 2000 disk.

• Activating the application.

• Configuring the application.

The detailed procedure of how to perform these operations is not specified and described in this
manual. For further details, refer to the following documentation:

• Service Control Application for Broadband User Guide

• Service Control Application for Broadband Reference Guide
