Cisco Service Control Solution

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.

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.

Cisco Service Control Capabilities

• 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).

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.

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:

• Layer 7 stateful wire-speed packet inspection and classification

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

• Programmable system core for flexible reporting and bandwidth control

• Transparent network and BSS/OSS integration into existing networks

Chapter 1 General Overview

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.

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.

Subscriber Management

Service Control 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.

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 (RDR-Protocol). 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.

Information About Topology

Revised: September 17, 2012, OL-26790-01

This chapter describes the possible deployment topologies of the SCE 1000. The Cisco SCE solution offers several 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.

Information About Topology Considerations

There are several issues that must be considered 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?

• Physical installation configuration—Will the SCE Platform be installed as inline? Or will the SCE

Platform use an optical splitter?

• Redundancy—Must the system be designed to guarantee uninterrupted service? If so, there must be

a backup SCE Platform to assume operation in case of failure of the primary data link.

• Link failure and recovery—How should the SCE Platform respond to platform failure and

subsequent recovery? Should traffic flow continue even though the unit is not operating, or be halted until the platform is repaired/replaced? Should the unit actually resume operation when it is again operational?

SCE Platform Configuration

Chapter 3 Information About Topology

There are four topology-related parameters:

• Connection mode—Can be Inline or Receive-only, depending on the physical installation of the SCE

1000:

May be configured via either the setup command or the connection-mode command.

• Bypass mode when the SCE 1000 is not operational (on-failure)—This parameter determines

whether the system cuts the traffic or bypasses it when the SCE 1000 has failed.

May be configured via either the setup command or the connection-mode command.

• Status after reboot caused by fatal error or abnormal shutdown—This parameter determines whether

the SCE 1000 returns to normal operational state after a failure.

May be configured via either the setup command or the failure-recovery operation-mode command.

• Link failure reflection—This parameter determines the behavior of the system when there is a link

problem. In some topologies it is required that link failure on one port be reflected to the other port, to allow the higher layer redundancy protocol in the network to function correctly.

May be configured via the link failure-reflection command only.

Failure Detection Mechanism

Boot time diagnostics failure. When there is a failure in diagnostics testing at boot time the system will remain in failure status.

• Boot time diagnostics failure. When there is a failure in diagnostics testing at boot time the system

will remain in failure status.

Chapter 3 Information About Topology

• Watchdog mechanism. There are two types of watchdogs:

–

• Run time hardware tests. The system periodically tests the hardware components for error. If a

hardware component is malfunctioning, it will be discovered by the system within seconds.

Bypass Mechanism

The SCE 1000 includes a Network Interface Card with a bypass mechanism that is enabled upon SCE 1000 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 1000 processes the traffic for

monitoring and control purposes.

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

SCE 1000 to process the traffic for monitoring only.

Bypass Mechanism

HW watchdog. A hardware mechanism that detects control entity failure.

SW watchdog. A software mechanism that periodically checks for software failures in the SCE 1000. If a failure is detected, an error massage is sent and the SCE 1000 reboots.

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

at layer 1).

Functionality

The SCE 1000 can serve one of two general functions:

• Monitoring and Control—The SCE 1000 monitors and controls traffic flow. Decisions are enforced

• Monitoring only—The SCE 1000 monitors traffic flow, but cannot control it.

Chapter 3 Information About Topology

by the SCE 1000 depending on the results of the monitoring functions of the SCE 1000 and the configuration of the Service Control Application for Broadband or Mobile solution.

To perform control functions, the SCE 1000 must be physically installed as an inline installation and the connection mode must be “inline”.

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

Information About Physical Installation

There are two options for the physical installation configuration of the SCE 1000 Platform:

• Inline installation (provides control functionality).

• Out-of-line installation utilizing an external optical splitter

The physical installation determines the connection mode that should be configured.

• Bump-in-the-Wire (Inline) Topology, page 3-5

• External Splitting (Receive-only) Topology, page 3-6

Bump-in-the-Wire (Inline) Topology

Typically, the SCE 1000 is connected on a full duplex line between two devices (Router, BRAS, and so forth). When the SCE 1000 is installed as a bump-in-the-wire, it physically resides on the data link between the subscriber side and the network side, and can both receive and transmit traffic (Figure 3-1).

External Splitting (Receive-only) Topology

In external splitting, an external optical splitter resides physically on the GBE link between the subscriber side and the network side (Figure 3-2). In this topology, the traffic passes through the external splitter, which splits traffic to the SCE 1000. The external splitter is connected to the SCE 1000 via Rx links only. The SCE 1000, therefore, receives traffic only. It does not transmit.

Figure 3-2 External Splitting (Receive-only) Topology

Chapter 3 Information About Topology

An external splitting installation is referred to as receive-only connection mode.

Note that in an external splitting installation, the SCE 1000 has only traffic monitoring capabilities.

Note Receive-only topologies can also be implemented using a switch. Such a switch must support SPAN

functionality that includes separation between ingress and egress traffic and multiple SPAN-ports destinations.

Information About Redundancy

• Redundancy, page 3-7

• Two Platforms on Parallel Links in Bump-in-the-Wire Topology, page 3-7

Redundancy

When a high degree of reliability is desired, a second SCE 1000 Platform should be installed to provide backup operation capabilities. This redundant SCE 1000 guarantees uninterrupted functioning of all SCE 1000 operations.

Note Redundancy is possible in inline installations only.

A single SCE 1000 platform does not provide redundancy for SCE 1000 control functions. In case of failure of the SCE 1000 unit, the SCE 1000 simply bypasses the traffic; the traffic link is not cut, but no control or monitoring functionality is available.

Information About Redundancy

Two Platforms on Parallel Links in Bump-in-the-Wire Topology

Using two SCE 1000 platforms on parallel links provides redundancy for all SCE 1000 features. In case of failure in the active platform, the backup SCE 1000 unit takes over.

Using redundant SCE 1000 platforms is applicable as an overlay to a customer’s redundant topology, on condition that the entire traffic of a specific subscriber (end station, subnet or VLAN) is flowing through one link only. Both links may be active, providing that the subscriber traffic is mutually exclusive.

This redundancy solution addresses any failure in the SCE 1000 platform itself. It is based on the idea that any fatal hardware or software failure will cause the platform to “cut” the link. A “cut” link will cause the routers/switches on both ends to switch the traffic to the standby link. On the standby link, the traffic is analyzed and policies enforced by the standby SCE 1000, which, after the failure, acts as the active SCE 1000.

Note that when both links are simultaneously independently active and redundant for the other link (as is the case when HSRP with two virtual routers is used), if one link fails, its traffic is directed to the other link. However, the overall supported load in the link that is now carrying all the traffic is only equal to one link, not two.

During setup of this topology, the configuration of the two SCE 1000 platforms is done through multi-box configuration. This ensures that both hold the same configurations and policies. The functional operation of switching from the active to standby, SCE 1000 is contingent upon the fact that the two SCE 1000 platforms are in the same Domain. All configurations performed on this Domain are automatically updated on both SCE Platforms. Both boxes should also be assigned to the same Subscriber Domain. For more information on Domains, see the Cisco Service Control Management Suite

Subscriber Manager User Guide.

OL-26790-01

The common protocols used for redundancy traffic switching between network elements such as routers and switches in networks are Spanning-Tree in layer2, HSRP in layer3 (usually used in data-centers), and other common routing protocols like OSPF or RIP.

Cisco SCE 1000 2xGBE Installation and Configuration Guide

3-7

Page 38

Two Platforms on Parallel Links in Bump-in-the-Wire Topology

Note When using routing/switching protocols that perform load balancing as well, the load balancing

capabilities should be disabled.

The transition to the backup SCE 1000 platform is transparent. Once the routers/switches detected that traffic has been cut, they start sending traffic through the redundant link. After this occurs, the failed SCE 1000 can be fixed/replaced with no downtime, since the box is effectively disconnected from the network. After fixing/replacing the failed SCE 1000, you must copy the configuration of the current active SCE 1000 to the fixed/replaced SCE 1000.

The backup and restore procedures used for copying policies and Service Configurations from one SCE 1000 to the next are detailed in the Cisco Service Control Application for Broadband User Guide.

Chapter 3 Information About Topology

Information About Failure and Recovery

It is important to decide how the system should behave in case of the failure of the SCE 1000, both during the time that the unit is down and after recovery. This decision is influenced by several factors:

• Physical installation (connection mode)

• Redundancy

• Relative importance of maintaining connectivity vs. the continuity of the value-added services that

the SCE 1000 enables.

Physical Installation

In a link connection via an external optical splitter, SCE 1000 failure does not affect traffic flow, which continues through the external optical splitter. When the SCE 1000 detects a failure that requires a recover by reboot, it immediately switches to Cutoff mode, stopping all traffic flow over the link until the SCE 1000 unit is restored to operation.

When operation resumes, the defined operational bypass mode is automatically resumed.

The configuration of a bump-in-the-wire installation depends on the remaining two factors.

Information About Failure and Recovery

Redundancy

Redundancy requires two platforms on parallel links, one active and one standby, in inline topology. When the active SCE 1000 platform detects a failure situation, it will immediately switch to Cutoff mode, causing the routers/switches on both ends to switch the traffic to the standby link and thus activate the standby SCE 1000 platform.

There are two options when the failed SCE 1000 platform is finished reloading:

• It may either actually resume operation in the defined operational bypass mode, returning to its

status as the active SCE 1000 platform.

• It may remain inactive in the failure bypass mode.

Maintaining the Network Links Versus Maintaining SCE 1000 Platform Functionality

When a single SCE 1000 is deployed, the user may decide that in case of a failure, maintaining the network link is more important than providing the SCE 1000 functionality. In this scenario, when the SCE 1000 detects a failure that requires a reboot process for recovering, it immediately switches to Bypass mode, allowing all traffic to bypass the SCE 1000. The SCE 1000 stays in Bypass mode maintaining the network link, albeit without SCE 1000 processing, until the SCE 1000 fully recovers from the failure and is ready to resume normal functioning.

Alternatively, the user may decide that the SCE 1000 functionality is sufficiently crucial to require severing the link if the SCE 1000 platform fails. In this case, when the SCE 1000 detects a failure that requires a reboot process for recovering, it immediately switches to Cutoff mode, stopping all traffic flow. The SCE 1000 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 1000 to sense that the link is down.

Information About Topology-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 1000.

• Connection Mode Parameter, page 3-10

• On-Failure Mode Parameter, page 3-10

• Link Failure Reflection Parameter, page 3-11

• Status of the SCE 1000 After Abnormal Boot, page 3-11

Connection Mode Parameter

The connection mode parameter refers directly to the physical topology in which the SCE 1000 is installed. Installation is possible in either of the two following modes:

• Inline — The SCE 1000 resides on the data link between the subscriber side and the network side,

thus both receiving and transmitting packets.

Chapter 3 Information About Topology

• Receive-only — The SCE 1000 does not reside physically on the data link. Data is forwarded to the

SCE 1000 via an external optical splitter. The SCE 1000 itself receives only and does not transmit.

Note Default value = Inline

The connection mode parameter is determined by the physical deployment of the SCE 1000 as follows:

• Bump-in-the-wire installation = Inline connection mode.

• External optical splitter installation = Receive-only connection mode.

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 1000 is not operational due to platform failure or boot:

• Bypass — The optical splitter forwards traffic with no intervention of the control application

running in the SCE 1000 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 non-operational status.

Cisco SCE 1000 2xGBE Installation and Configuration Guide

OL-26790-01

Page 41

Chapter 3 Information About Topology

In a single SCE 1000 topology, the value of this parameter is determined by whether or not the link can be completely cut when the SCE 1000 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.

Link Failure Reflection Parameter

The link failure reflection refers to the behavior of the SCE 1000 when one of the data links fails. Some network redundant topologies require a layer 1 cutoff in order for the network element to recognize the link failure and translate it into action (switch to redundant link). In this case, if one of the ports fails, it must be reflected to the other port as well.

• Link failure-reflection — When one data port link fails, the SCE 1000 forces the other port link

down as well. The port will be forced down as long as the first port link is down. When the problematic port link goes up, the other port link will also be turned on again.

• No link failure-reflection — Link failure is not reflected to the other port.

Link Failure Reflection Parameter

Note Default value = no link failure-reflection

Status of the SCE 1000 After Abnormal Boot

This parameter determines whether the SCE 1000 returns to normal operational state after a reboot caused by fatal error or abnormal shutdown. In general, it is desirable that the SCE 1000 resume operation, and as promptly as possible. However, in a redundant topology, a recovered SCE 1000 may remain non-operational. In this case the platform that had been the backup and is currently active will remain active.

The two options for this parameter are:

• Operational—The status of the SCE 1000 after abnormal boot is operational. The platform

automatically resumes functioning in the defined operational link bypass mode.

• Not Operational—The status of the SCE 1000 after abnormal boot is not operational. The platform

remains in the defined failure link bypass mode.

This option is to be used only in a redundant topology where a second, operational platform exists.

Note Default value = Operational for all non-redundant systems.

Note Must be explicitly configured for redundant topologies.

Information About Site Requirement Guidelines

The environmental monitoring functionality in the v 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 1000 chassis free from dust.

Planning a proper location for the SCE 1000 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, page 4-3

• Site Requirements, page 4-4

Information About Site Requirement Guidelines

Airflow

Figure 4-2 Airflow Through the SCE 1000

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 1000 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. Figure 4-2 illustrates the airflow through the SCE 1000.

Note Remember to leave a two inch (5 cm) clearance on both sides of the SCE 1000 and five inches (12.7 cm)

at the rear for adequate airflow for the inlet and exhaust vents.

Chapter 4 Installation and Maintenance

Installing the SCE 1000 Platform

The SCE 1000 operates as either a tabletop or a rack-mounted unit. A rack-mounting kit is included with the SCE 1000 when it is shipped from the factory. The kit provides the hardware needed to mount the SCE 1000 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 cross rail supports

included in the kit

If you are not rack-mounting your SCE 1000, 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 1000 platform, including how to install the SCE 1000 in a rack, how to install the SCE 1000 on a tabletop or workbench, and how to properly ground the SCE 1000 platform. The section contains the following topics:

• Installation Precautions, page 4-5

• How to Install the SCE 1000 on a Workbench or Tabletop, page 4-6

• What to Do Next, page 4-6

• Rack-Mounting a SCE 1000 Platform, page 4-7

Installing the SCE 1000 Platform

• How to Attach a Chassis Ground Connection, page 4-13

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 Information About Site Requirement Guidelines, page 4-3 and the Site Preparation and Safety Guide.

When installing the SCE 1000, 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 1000. For descriptions and illustrations regarding airflow, see Airflow, page 4-3.

• Do not place the SCE 1000 on the floor during installation. Dust that accumulates on the floor is

drawn into the interior of the SCE 1000 by the cooling fans. Excessive dust inside the SCE 1000 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 1000 for installing

and rudimentary maintenance for accessing network cables or equipment.

• Ensure that the SCE 1000 will receive adequate ventilation. Do not install the SCE 1000 in an

enclosed cabinet where ventilation is inadequate!

• Provide an adequate chassis Ground (earth) connection for the SCE 1000 (see How to Attach a

Chassis Ground Connection, page 4-13 for instructions).

Step 3 Repeat steps 1 and 2 on the other side of the SCE 1000.

This completes the steps for attaching the rack-mount brackets to the SCE 1000.

If mounting the SCE 1000 in a rack with only two posts, skip to How to Mount the System to the Rack.

If mounting the SCE 1000 in a rack with four posts, proceed to the next step to attach the cross rail supports to the rack.

How to Attach the Cross Rail Supports to the Rack

When mounting in a rack with four posts (front and back) the two cross rail supports are mounted one on each side of the rack. The SCE 1000 then slides into these cross rails, which support the weight of the unit.

Note Cisco recommends that you allow at least 1 or 2 inches (2.54 or 5.08 cm) of vertical clearance between

the SCE 1000 and any equipment directly above and below it.

Rack-Mounting a SCE 1000 Platform

SUMMARY STEPS

How to Attach a Chassis Ground Connection

Before you connect the power or turn on the power to the SCE 1000 platform, it is required that you provide an adequate chassis ground (protective earth) connection for the SCE 1000 chassis. A grounding kit is provided with each SCE 1000.

Use the grounding kit to properly ground the SCE 1000 chassis.

Note When installing the unit, the chassis ground connection must always be made first and disconnected last.

Step 1 From the enclosed grounding kit, remove the necessary materials—the grounding cable (green and

yellow colored cable) and pairs of hex nuts and spring washers.

Step 2 On the rear panel of the SCE 1000, locate the chassis grounding connector (refer to the appropriate figure

for an AC- or DC-powered SCE 1000 below).

Step 3 Attach the grounding cable (green and yellow colored cable), firmly fastening the (enclosed) hex nuts

and spring washers with a #¼” hex wrench (refer to the appropriate figure (Figure 4-12 or Figure 4-13) for an AC- or DC-powered SCE 1000 below).

How to Attach a Chassis Ground Connection

The other side of the grounding cable must be connected to the site equivalent of the AC earth.

Removing and Replacing a Power Supply Unit

The procedures for removing and replacing the AC-input or DC-input power supply are explained in the following sections:

Do not remove or install modules without using appropriate anti-static guard measures. The SCE 1000 includes an anti-static wrist strap in the accessory kit. Attach the copper tape strap to an unpainted metal surface on the chassis. You may leave the strap connected to the chassis when your have finished.

Never install an AC power module and a DC power module in the same chassis.

• Information About the Power Supply, page 4-15

• Powering Down the Power Supply Unit and Disconnecting Input Power, page 4-18

• How to Remove the Power Supply Unit, page 4-19

Information About the Power Supply

The SCE 1000 is available in two power options:

• Dual line feed AC power — SCE 1000 is shipped with two appropriate AC power supply cords.

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

Reconnect DC-Input Power Supply Unit, page 4-22).

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 1000 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 1000, 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 Figure 4-14 or

Figure 4-15).

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 is 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.

If no value appears in the brackets [], or more than one option appears [yes/no], then this parameter does not have a default value.

• To accept the default value, press Enter.

• If you need more information about any parameter, type ? and press Enter.

A help message will appear describing the expected format of the parameter and any other requirements.

• To jump to the end of the setup dialog at any point, accepting all remaining default values, press ^z .

• In certain cases, there will be two or more logically related parameters within a menu. In these

situations, it is not permitted to jump to the end of the setup dialog until all related parameters are configured. If you try to jump to the end of the setup dialog, the following message will appear:

“Sorry, Skipping is not allowed at this stage.”

• Certain groups of related parameters, such as time, date, and SNTP settings, form sub-dialogs or

menus within the setup dialog. You may skip an entire menu, thereby accepting all default values for the parameters within the menu.

Each group of related parameters is prefaced by a question, asking whether you want to enter the menu. To skip the menu, answer no (“n”) to the question.

Step 1: Configuring Initial Settings

Example

Would you like to enter the SNMP configuration menu? n

To abort the setup dialog at any point without making any configuration changes, press ^c . All changes already entered will be lost, with the exception of time settings.

Step 1: Configuring Initial Settings

Step 7: Configuring Access Control Lists (ACLs)

Information About Access Control Lists

• Configuring ACLs, page 5-14

• Entry Formats, page 5-14

• Order of Entries, page 5-15

Configuring ACLs

The SCE 1000 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:

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.

2. Assign the ACLs to the appropriate management interface.

Chapter 5 Connecting the Management Interfaces and Performing Initial System Configuration

Entry Formats

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

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 Tab l e 5-2 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)

5-14

Cisco SCE 1000 2xGBE Installation and Configuration Guide

OL-26790-01

Page 83

Chapter 5 Connecting the Management Interfaces and Performing Initial System Configuration

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 7: Configuring Access Control Lists (ACLs)

Step 1 Enter the Access Control Lists configuration menu.

Would you like to enter the Access lists configuration menu? [no]:y

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.

Would you like to create new Access lists or modify existing lists? [no]: y

If you choose not to create or edit Access Control Lists, skip to.

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.

Step 4 Begin adding entries to the selected list.

Indicate whether this entry is permitted access or denied access.

• To permit access press Enter.

• To deny access type n and press Enter.

Step 5 Type the IP address to be added to this list, and press Enter.

Note that there is no default for this parameter.

Enter IP address or the word ‘any’ to denote any IP address:

OL-26790-01

Step 6 If you entered a specific IP address, enter the wildcard bits to define a range of IP addresses and press

Enter. (See Entry Formats, page 5-14.)

To define an individual IP address, type 0.0.0.0 and press Enter.

There is no default for this parameter.

Enter wildcard bits:

Cisco SCE 1000 2xGBE Installation and Configuration Guide

5-15

Page 84

Step 7: Configuring Access Control Lists (ACLs)

Step 7 The maximum number of entries in an ACL is 20.

If the “any” option was used, no other IP addresses may be added to the list.

• To add more entries, type y and press Enter

Would you like to add another entry to this list? [no]:y

• Enter up to 20 entries as described in step 5 and step 6.

• When all entries have been added, press Enter

Would you like to add another entry to this list? [no]:

Step 8 When all entries are added to one list, you are asked whether you would like to create another ACL. You

may define up to 99 ACLs.

• To create another ACL, type y and press Enter

Would you like to configure another list? [no]: y

• Enter up to 20 IP addresses in this new ACL, as described in step 5 and step 6.

• When all ACLs have been created, press Enter.

Would you like to configure another list? [no]:

Chapter 5 Connecting the Management Interfaces and Performing Initial System Configuration

Examples

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

Step 9 Restrict IP access to the SCE 1000 by assigning the appropriate ACL.

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

To accept the default ACL, press Enter.

Enter IP access-class [0]:

Step 10 Restrict Telnet access to the SCE 1000 by assigning the appropriate ACL.

Type the number of the ACL to be assigned to the Telnet interface and press Enter.

To accept the default ACL, press Enter.

Enter Telnet access-class [0]: 2

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 (for example

ping, SNMP polling, and so forth).

• 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.

[no]: Enter IP access-class [0]: 1 Enter Telnet access-class [0]: 2

Step 8: Configuring SNMP

Example 2:

This example skips the first section of the dialog (creating/modifying), and proceeds directly to assign existing ACLs.

Would you like to enter the Access lists configuration menu? [no]: y Would you like to create new Access lists or modify existing lists? [no]: Enter IP access-class [0]: 10 Enter Telnet access-class [0]: 22

Step 8: Configuring SNMP

Managing the SCE 1000 is possible also via a Network Management System (NMS) that supports SNMP. By default, SNMP is disabled on the SCE 1000.

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 1000).

Step 9: Configuring the Topology-Dependent Parameters

• About the Topology-Dependent Parameters

• Examples

About the Topology-Dependent Parameters

The topology configuration menu is a series of guided questions relating to the deployment of the SCE 1000 in the network and its mode of operation. Values for the parameters are configured based on the user answers.

Cisco SCE 1000 2xGBE Installation and Configuration Guide

5-20

OL-26790-01

Page 89

Chapter 5 Connecting the Management Interfaces and Performing Initial System Configuration

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 Information About Topology for a comprehensive discussion of topology and the related parameters.)

There are three topology-related parameters:

• Connection mode—Can be either Inline or Receive-only, depending on the physical installation of

the SCE 1000

• Bypass state when the SCE 1000 is not operational (on-failure)—This parameter determines

whether the system cuts the traffic or bypasses it when the SCE 1000 has failed.

• Status after reboot caused by fatal error or abnormal shutdown—This parameter determines whether

the SCE 1000 returns to normal operational state after a failure

The procedure described below is a hypothetical presentation of all the questions in the topology configuration. In actual practice, it is impossible for all questions to be presented in any one configuration, as this part of the dialog is not linear like the other sections, but branches depending on the parameter values entered.

Study the examples that follow to understand the procedure for various topologies.

Step 1 Enter the topology configuration menu.

Would you like to enter the Topology configuration menu? [no]: y

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 1000 and the remote management host are explained in the following sections:

• How to Cable the Management Port

• How to Verify Management Interface Connectivity

How to Cable the Management Port

The SCE 1000 has two management ports, labeled Mng1 and Mng 2.

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 1000, as shown in Figure 5-2.

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.

Chapter 5 Connecting the Management Interfaces and Performing Initial System Configuration

If the Link LED on the SCE 1000 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 1000 still does not light, verify that the cable is connected correctly to the appropriate network element on its second end.

How to Verify Management Interface Connectivity

If the SCE 1000 platform has been powered up, test now to verify that connectivity has been established between the SCE 1000 and the remote management host. If the SCE 1000 platform is not powered up, perform this step after starting the SCE 1000 platform.

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).

At this point, check that the Link/Active LED is green.

How to Verify Management Interface Connectivity

Example

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 1000 by

typing ping and the SCE 1000 IP address, and pressing Enter (see the example, below).

Note Please note that only 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.

The following example displays a typical ping response where the target IP address is 10.1.1.201.

C:\>ping 10.1.1.201 pinging 10.1.1.201 ... PING 10.1.1.201: 56 data bytes 64 bytes from host (10.1.1.201): icmp_seq=0. time=0. ms 64 bytes from host (10.1.1.201): icmp_seq=1. time=0. ms 64 bytes from host (10.1.1.201): icmp_seq=2. time=0. ms 64 bytes from host (10.1.1.201): icmp_seq=3. time=0. ms

----10.1.1.201 PING Statistics---4 packets transmitted, 4 packets received, 0% packet loss round-trip (ms) min/avg/max = 0/0/0

Single Link: Inline Topology

In the inline topology (Figure 6-1), the SCE 1000 resides physically on the GBE (Gigabit 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 1000 usually connects to a router or layer 3 switch network element.

In the inline or bump-in-the-wire topology, illustrated in the diagram above, the SCE 1000 resides physically on the data link between the subscriber side, usually 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 side, usually a router or layer 3 switch network element. This is the inline topology, providing both traffic monitoring and control capabilities.

In this topology, all the traffic of the SCE 1000 is deployed as a transparent layer2 overlay on the customer’s existing network.

Single Link: Receive-only Topology

In this topology (Figure 6-2), an external optical splitter resides physically on the GBE link between the subscriber side and the network side. The external splitter is connected to the SCE 1000 via Rx links only.

In this topology, the traffic passes through the external splitter, which splits traffic to the SCE 1000. The SCE 1000, therefore, is in receive-only topology, having only traffic monitoring capabilities.

Note Receive-only topologies can also be implemented using a switch. Such a switch must support SPAN

functionality that includes separation between ingress and egress traffic and multiple SPAN-ports destinations.

How to Configure Gigabit Ethernet Auto-Negotiation

By default, the SCE 1000 GBE line interface ports are configured with auto-negotiation disabled.

Note Auto-negotiation must be disabled when the SCE 1000 is deployed via an external optical splitter

(receive-only topology)

Note If you change any parameters, you must save the new configuration settings. Type copy running-config

startup-config, and press Enter.

Step 1 At the SCE 1000# prompt, type configure and press Enter.

Enters Global Configuration Mode.

Step 2 At the SCE 1000(config)# prompt, type interface Gigabit Ethernet 0/ port number, and press Enter.

Enters the Gigabit Ethernet Interface configuration mode for the specified GBE port.

Port number is the number of the selected port (1 or 2).

Step 3 At the SCE 1000(config if)# prompt, type auto-negotiate and press Enter.

Enables auto-negotiation for the GBE interface.

Step 4 At the SCE 1000(config if)# prompt, type exit and press Enter.

Returns to Global Configuration Mode, from which you can enter the Gigabit Ethernet Interface configuration mode for the remaining GBE port.

Repeat this procedure to configure auto-negotiation for the other GBE port interface.

Connecting the GBE Line Interface Ports

The following sections present the general procedure for cabling the GBE interface ports. Refer to

Cabling Diagrams, page 6-2 to find the appropriate cabling diagram for the topology of your system for

the specific connections required.

Note When installing an External Optical Bypass module, the SCE 1000 line ports are connected to the

module. See External Optical Bypass Module for complete instructions.
