Cisco Service Control Overview

This chapter provides a general overview of the Cisco Service Control solution. It introduces the Cisco service control concept and capabilities.

It also briefly describes the hardware capabilities of the service control engine (SCE) platform and the Cisco specific applications that together compose the complete Cisco service control solution.

• Cisco Service Control Solution, page 1-1

• Cisco Service Control Capabilities, page 1-2

• SCE Platform Description, page 1-3

• Management and Collection, page 1-5

Cisco Service Control Solution

The Cisco service control solution is delivered through a combination of hardware and specific software solutions that address various operational and business-related challenges. Service providers can use the SCE platform to support classification, analysis, and control of Internet and IP traffic.

CHA PTER

Service control enables service providers to:

• Capitalize on existing infrastructure.

• Analyze, charge for, and control IP network traffic at multigigabit wire line speeds.

• Identify and target high-margin content-based services and enable their delivery.

As 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.

Cisco service control solutions allow the service provider to capture profits from IP services through detailed monitoring, precise, real-time control, and awareness of applications as they are delivered.

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 layer of service intelligence and control to existing networks that can:

Cisco SCE8000 Installation and Configuration Guide, Rel 3.1.7

OL-16478-02

1-1

Cisco Service Control Capabilities

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

• Provide customer-intuitive tiered application services and guarantee application service level

agreements (SLAs)

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

• Identify network abusers who are violating the acceptable use policy (AUP)

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

• Enforce the AUP

• Integrate Service Control solutions easily with existing network elements and business support

systems (BSS) and operational support systems (OSS)

Cisco Service Control Capabilities

The core of the Cisco service control solution is the 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:

Chapter 1 Cisco Service Control Overview

• 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 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 through 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 bandwidth (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 adapt to new services and

applications in the 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 integration process.

1-2

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

speed.

Chapter 1 Cisco Service Control Overview

SCE Platform Description

The SCE family of programmable network devices performs application-layer stateful-flow inspection of IP traffic, and controls the traffic based on configurable rules. The SCE platform is a network device that uses ASIC components and reduced instruction set computer (RISC) processors to exceed beyond packet counting and expand into the contents of network traffic. Providing programmable, stateful inspection of bidirectional traffic flows, and mapping these flows with user ownership, SCE platforms provide real-time classification of network use. The classification provides the basis of the SCE platform advanced traffic-control and bandwidth-policing functionality. Where most bandwidth control functionality ends, the SCE platform provides further control and shaping options, including:

• Layer 7 stateful wire-speed packet inspection and classification

• Robust support for more than 600 protocols and applications, including:

–

General—HTTP, HTTPS, FTP, Telnet, Network News Transfer Protocol (NNTP), Simple Mail Transfer Protocol (SMTP), Post Office Protocol 3 (POP3), Internet Message Access Protocol (IMAP), Wireless Application Protocol (WAP), and others

–

Peer-to-Peer (P2P) file sharing—FastTrack-KazaA, Gnutella, BitTorrent, Winny, Hotline, eDonkey, DirectConnect, Piolet, and others

–

P2P VoIP—Skype, Skinny, DingoTel, and others

SCE Platform Description

–

Streaming and Multimedia—Real Time Streaming Protocol (RTSP), Session Initiation Protocol (SIP), HTTP streaming, Real Time Protocol (RTP) and Real Time Control Protocol (RTCP), and others

• Programmable system core for flexible reporting and bandwidth control

• Transparent network and BSS and OSS integration into existing networks

• Subscriber awareness that relates traffic and usage to specific customers

Figure 1-1 illustrates a common deployment of an SCE platform in a network.

Management and Collection

Subscriber Management

Where the Cisco service control application for broadband (SCA BB) enforces 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 OSS and 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.

Chapter 1 Cisco Service Control Overview

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 standards-based approach makes it easy to manage multiple devices in a large network.

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

Data Collection

Data collection occurs as follows:

1. All analysis and data processing functions of the SCE platform result in the generation of Raw Data

Records (RDRs), which the SCE platform forwards using a simple TCP-based protocol (RDR-Protocol).

2. RDRs are processed by the Cisco service control management suite collection manager.

3. The collection manager software is an implementation of a collection system that receives RDRs

from one or more SCE platforms. It collects these records and processes them in one of its adapters. Each adapter performs a specific action on the RDR.

RDRs contain a variety of information and statistics, depending on the configuration of the system. Three main categories of RDRs include:

1-6

• Transaction RDRs—Records generated for each transaction, where a transaction is a single event

detected in network traffic. The identification of a transaction depends on the particular application and protocol.

• Subscriber Usage RDRs—Records generated per subscriber, describing the traffic generated by that

subscriber for a defined interval.

• Link RDRs—Records generated per link, describing the traffic carried on the link for a defined

interval.

Introduction to SIPs and SPAs

SIPs and SPAs are a new carrier card and port adapter architecture used to increase modularity, flexibility, and density across Cisco Systems routers for network connectivity. This section describes the SIPs and SPAs and provides some guidelines for their use.

• SPA Interface Processors, page 2-4

• Specifying the SIP Subslot Location for a SPA, page 2-5

• Shared Port Adapters, page 2-5

• Modular Optics, page 2-6

• XFP Connections, page 2-6

SPA Interface Processors

The SIP module supported by the Cisco SCE8000 chassis is the SCE8000-SIP.

The following list describes some of the general characteristics of a SIP:

2-4

• A SIP is a carrier card that inserts into a slot in the chassis like a line card. It provides no network

connectivity on its own.

• A SIP contains one or more subslots (bays), which are used to house one or more SPAs. The SPA

provides interface ports for network connectivity.

• During normal operation the SIP should reside in the router fully populated either with functional

SPAs in all subslots, or with a blank filler plate (SPA-BLANK=) inserted in all empty subslots.

Specifying the SIP Subslot Location for a SPA

Cisco SCE8000-SIP subslots begin their numbering with “0” and have a horizontal orientation.

Figure 2-3 shows the subslot numbering for the Cisco SCE8000-SIP.

The Cisco SCE8000-SIP supports four subslots for the installation of SPAs, as follows:

• SIP subslot 0—Top–left subslot

• SIP subslot 1—Top–right subslot

• SIP subslot 2—Bottom–left subslot

• SIP subslot 3—Bottom–right subslot

Figure 2-3 SPA Module Subslot Location

Introduction to SIPs and SPAs

Shared Port Adapters

The SPA supported by the Cisco SCE8000-SIP is the 1-Port 10-Gigabit Ethernet SPA, SPA-1X10GE-L-V2

The following list describes some of the general characteristics of a SPA:

• A SPA is a modular type of port adapter that inserts into a subslot of a compatible SIP carrier card

to provide network connectivity and increased interface port density. The Cisco SCE8000-SIP can hold up to four SPAs.

Since the interfaces are connected in subscriber/network pairs, either two or four SPAs must be installed.

• The supported SPA is a single-height SPAs, which inserts into one SIP subslot. (See Figure 2-4.)

Figure 2-4 Single-Height SPA Size

• Each SPA provides a one 10GBE port, which is the interface to either subscriber or network traffic.

These interfaces can be individually configured using the Cisco command-line interface (CLI).

• Either a blank filler plate or a functional SPA should reside in every subslot of an SIP during normal

operation to maintain cooling integrity. Blank filler plates are available in single-height form only.

Since the interfaces are connected in subscriber/network pairs, the SCE8000-SIP must be either fully populated or have both the bottom bays covered with blank filler plates.

Modular Optics

The SPAs implement 10GBE small form-factor pluggable (XFP) optical transceivers to provide network connectivity. An XFP module is a transceiver device that mounts into the front panel to provide network connectivity.

Note It is highly recommended only to use the XFP modules listed as supported in this document. Use of

unsupported or unqualified XFP modules may affect reliability or operation.

Figure 2-5 10GBE Small Form-factor Pluggable (XFP)

Chapter 2 Introduction to the Cisco SCE8000 Platform

The interface connector on the 1-Port 10-Gigabit Ethernet SPA is a fiber optic receiver that supports one XFP.

The types of optics modules that have been qualified for use with the 1-Port 10-Gigabit Ethernet SPA on the Cisco SCE8000 platform are as follows:

• XFP-10GLR-OC192SR

• XFP-10GER-OC192IR

• XFP-10GZR-OC192LR

• XFP-10G-MM-SR

XFP Connections

The qualified XFPs include an optical transmitter and receiver pair integrated with Clock and Data Recovery (CDR) integrated circuits. The XFPs provide high-speed serial links at 10.3125 Gbps on single mode fibers.

The transmit side recovers and retimes the 10 Gbps serial data and passes it to a laser driver. The laser driver biases and modulates a laser, enabling data transmission over fiber through an LC connector. The receive side recovers and retimes the 10 Gbps optical data stream from a photo detector trans impedance amplifier and passes it to an output driver.

See the label on the XFP for technology type and model.

XFP dimensions are:

• Height 12.5 mm

2-6

• Width 18.35 mm

• Length 71.1mm

The Cisco SCE8000 platform optical bypass module preserves the service provider 10GBE links under all circumstances. At power failure the bypass is automatically activated. It can also be activated by the Cisco SCE8000 software.

The Cisco SCE8000 platform already includes an internal electrical bypass, but it is strongly recommended to use the optical bypass module for addressing the following scenarios:

• During platform reboot (SW reload)—If the external bypass module is not used, there is a 5-second

period (at most) during which the link is forced down (cutoff functionality).

• During a power failure —The Cisco SCE8000 has two power supplies. A power failure occurs only

when both of them fail.

In a case where the Cisco SCE8000 platform must be replaced, it is possible to remove the bypass modules from the SCE8000 chassis without disconnecting them from the network and then reinstall them in the new SCE platform, so that traffic links are preserved even in a case of complete failure and replacement of the Cisco SCE8000 platform. (See Replacing the Optical Bypass Module without

Disrupting Traffic on the Link, page 9-26.)

Optical Bypass Functionality

The optical bypass module is connected bump-in-the-wire in the 10-GBE link. It is then connected to the Cisco SCE8000 platform with two types of connections:

• 10GBE optical connections for data link traffic — 10 GBE connections from the optical bypass

module to one pair of the 10GBE SPA ports.

• Control connection — Connection to the RJ-11 External Bypass connector on the SCE8000-SCM,

so the optical bypass is activated if the Cisco SCE8000 platform fails.

The Cisco SCE8000 Optical Bypass

Optical Bypass Module Connectivity

The optical bypass module functions as follows:

• Under normal conditions, the bypass module directs traffic to flow via the Cisco SCE8000.

• Under failure conditions, the optical bypass shortcuts the interfaces that are connected to the traffic

link, and all traffic flows through the optical bypass module, bypassing the SCE platform.

Figure 2-7 Optical Bypass Module Connectivity

Optical Bypass Module (OPB-SCE8K)

There are two types of optical bypass modules to support different optic types:

OL-16478-02

The optical bypass module is installed either internally, in slot #4 of the Cisco SCE8000 chassis or in an external mounting panel in the rack.

Up to two optical bypass modules can be mounted internally, supporting inline insertion into two links.

Up to four optical bypass modules can be mounted using an external mount panel (OPB-SCE8K-EXT-PNL). A single panel can serve two SCE8000 platforms, each cutting two links or up to four SCE8000 platforms, each cutting a single link.

2-12

Figure 2-11 PWR-2700-DC/4

The AC-input and DC-input power supplies support redundancy. When power is removed from one supply, the redundant power feature causes the second supply to produce full power.

Cisco SCE8000 Installation and Configuration Guide, Rel 3.1.7

OL-16478-02

Chapter 2 Introduction to the Cisco SCE8000 Platform

Power Supply Cooling

Power supplies have built-in fans and are completely self-cooling. Air enters from the right of the fan and exits through the left.

Load Sharing

With two power supplies, each power supply concurrently provides approximately half of the required power to the system. If one power supply fails, the second power supply immediately assumes full power to maintain uninterrupted system operation. The second power supply enables load sharing and fault tolerance automatically; no software configuration is required.

The Cisco SCE8000 Platform

The Cisco SCE8000 is a solution for dual links with load sharing and asymmetrical routing and support for fail-over between two SCE platforms.

The Cisco SCE8000 is built to support wire speed processing of full-duplex 10GBE streams. The Cisco SCE8000 can, therefore, be deployed in a multi-link environment, in several different topologies.

• Single Cisco SCE8000 topology — Provides 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 Cisco SCE8000 topology (cascade) — Cascaded Cisco SCE8000s provide high-availability

and fail-over solution and maintain the line and service in case of Cisco SCE8000 failure

• Multi-Gigabit Service Control Platform (MGSCP) topology — For scalability, the Cisco SCE8000

platform supports the option to connect a multiple number of SCE platforms to a Cisco 7600 Series router used to perform load-balancing between the platforms.

Topology Considerations

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

• Functionality

Topology Considerations

Chapter 3 Cisco SCE8000 Topology and Topology-Related Parameters

— 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?

–

Monitoring and Control — The Cisco SCE8000 monitors and controls traffic flow. Decisions are enforced by the Cisco SCE8000 depending on the results of the monitoring functions of the Cisco SCE8000 and the configuration of the Service Control Application for Broadband or Mobile solution.

In order to perform control functions, the Cisco SCE8000 must be physically installed as an inline installation.

–

Monitoring only — The Cisco SCE8000 monitors traffic flow, but cannot control it.

Either an inline installation or an optical splitter or port SPAN installation may be used for monitoring only.

• Size

A Cisco SCE8000 deployment can range from a single 10GBE link to multiple platforms in a MGSCP topology.

A complete discussion on sizing the system is beyond the scope of this document. Information regarding the number of Cisco SCE8000 platforms required is related to the design considerations 'per link' (topology and redundancy factors) rather than to overall sizing of the system.

• Redundancy

Must the system be designed to guarantee uninterrupted Cisco SCE8000 functionality? If so, there must be a backup Cisco SCE8000 platform (or a backup for each platform in an MGSCP topology) to assume operation in case of failure of the primary device.

A backup SCE platform is connected in a cascade configuration with the primary SCE platform so that, although all processing is performed only in the active Cisco SCE8000, the standby Cisco SCE8000 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 Cisco SCE8000 fail.

Note that an MGSCP topology with multiple Cisco SCE8000 platforms provides more sophisticated redundancy options, but the basic decision on each link is the same: does it require a standby SCE platform or not?

• Link continuity

How should the Cisco SCE8000 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?

If link continuity is a high priority, an external optical bypass module can be installed on the link. (See Link Continuity, page 3-9 and The Cisco SCE8000 Optical Bypass, page 2-8.)

Note In cascade configuration, installation of an external optical bypass module is required.

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

3-2

• Physical topology of the system — The actual physical placement and connection of the Cisco

SCE8000 platform or platforms 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.

Single Link: Inline Topology

Typically, the Cisco SCE8000 is connected in a full duplex 10GBE link between two devices (Router, BRAS, etc.). When the Cisco SCE8000 is installed as an inline installation, it physically resides on the data link between the subscribers and the network.

Figure 3-2 Single Link: Inline Topology

When configuring the Cisco SCE8000, an inline installation is referred to as “inline” connection mode.

Dual link: Inline Installation

In this topology, one Cisco SCE8000 is connected inline in two full duplex, 10GBE links.

Chapter 3 Cisco SCE8000 Topology and Topology-Related Parameters

In case the two links are load-shared, asymmetrical routing might occur, and some of the flows may be split, that is, the upstream packets of the flow go on one link, and the downstream packets go on the other link.

When installed in this topology, the Cisco SCE8000 completely overcomes this phenomenon, and provides its normal functionality as if asymmetrical routing were not occurring in the two links.

Figure 3-3 Dual link: Inline Installation

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

Single Link: Receive-only Topology

In this topology, an optical splitter resides physically on the 10GBE link between the subscribers and the network. The traffic passes through the optical splitter, which splits traffic to the Cisco SCE8000. The Cisco SCE8000, therefore, only receives traffic and does not transmit.

Figure 3-4 Single Link: Receive-only Topology

When configuring the Cisco SCE8000, an optical splitter topology is referred to as “receive-only” connection mode.

Note that in an optical splitter topology, the Cisco SCE8000 only enables traffic monitoring functionality.

Physical Topologies

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.

Dual Link: Receive-Only Topology

In this topology, one Cisco SCE8000 is connected in receive-only mode to two full duplex, 10 Gig links using optical splitters. 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 Cisco SCE8000 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.

Dual Cisco SCE8000 Topology (Cascade)

In this topology, two cascaded Cisco SCE8000s are used. This allows a fail-over solution, where in case of a failure of one Cisco SCE8000 the functionality that the Cisco SCE8000 provides is preserved by the redundant platform.

This topology allows both control and monitoring functionality where redundancy is required and “inline” connection is used. The two Cisco SCE8000s are cascaded, so the primary Cisco SCE8000 processes the traffic of the two links, while the secondary Cisco SCE8000 only bypasses the traffic of its links to the primary Cisco SCE8000 for processing, and then bypasses the processed traffic back to the link. The two Cisco SCE8000s also exchange keep-alive messages and subscriber state information.

In case the primary Cisco SCE8000 fails, the two Cisco SCE8000s switch their roles, and this way fail-over is provided.

This fail-over solution preserves the Cisco SCE8000 functionality and the network link:

• The two Cisco SCE8000s are simultaneously aware of the subscriber contexts, and subscriber states

are constantly exchanged between them, such that if the primary Cisco SCE8000 fails, the secondary can take over with minimum state loss.

• When one Cisco SCE8000 fails (depending on the type of failure) its link traffic is still bypassed to

the functioning Cisco SCE8000 and processed there, so the traffic processing continues for both the links.

• The bypass of the traffic through the failed Cisco SCE8000 is configurable, and the user may choose

to always cutoff the line that goes through the failed Cisco SCE8000. 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 Cisco SCE8000.

• In addition, it is possible to configure the Cisco SCE8000 to use the external optical bypass device

so that in the event of any failure of the Cisco SCE8000, it will be used to provide link continuity. This ensures 100% link continuity at the expense of providing asymmetric routing functionality.

Multi-Gigabit Service Control Platform (MGSCP) Topology

In this topology, multiple Cisco SCE8000 platforms are connected to a Cisco 7600 Series router, which acts as a dispatcher between the platforms. The router contains two EtherChannels (ECs), one for the subscriber side and one for the network side, that perform load balancing for the SCE platform traffic. Traffic enters the first router, is distributed between the SCE platforms by the subscriber-side EC and then returns to the router so it can be forwarded to its original destination.

Physical Topologies

Figure 3-7 Basic MGSCP Topology

There are a number of variables to be considered in the MGSCP topology. Two of the main factors to be considered include:

• Type of SCE Platform Redundancy, page 3-8

• Redundant Cisco 7600 Series Router, page 3-8

Type of SCE Platform Redundancy

• All Active

All ports in the EC and all SCE platforms are active. If there is a failure in one of the SCE platforms, the links on the related ports in the EC will be down and the EC will automatically exclude it from the load distribution. The load will then be distributed between the remaining active SCE platforms.

Since the Cisco SCE8000 supports two links, this configuration requires one SCE platform per two links (two EC ports).

• N+1

'N' SCE platforms are active and one platform is on standby. The EC ports connected to the standby SCE platform must be configured as standby ports. In the case of failure of one of the SCE platforms, the EC ports connected to the failing SCE platform are shut and the standby EC ports, connected to the standby SCE platform, will be activated.

Since the Cisco SCE8000 supports two links, this configuration requires one SCE platform per two links (two EC ports), plus one extra SCE platform for standby.

Note that the standby SCE platform must be connected to the two highest-numbered ports, since EC behavior automatically designates these as the standby ports.

Chapter 3 Cisco SCE8000 Topology and Topology-Related Parameters

Redundant Cisco 7600 Series Router

Two Cisco 7600 Series routers can be used to provide network redundancy.

In this topology, one link on each Cisco SCE8000 platform is connected to each router. Therefore, one SCE platform is required for each link.

Chapter 3 Cisco SCE8000 Topology and Topology-Related Parameters

Link Continuity

The internal bypass mechanism of the Cisco SCE8000 allows traffic to continue to flow, if desired, even if the device itself is not fully functioning. In addition, the Cisco SCE8000 is designed with the ability to control up to two external optical bypass devices (one per link). This is needed because the internal bypass mechanism cannot maintain traffic flow in all cases.

Note that when the Cisco SCE8000 is connected to the network through an optical splitter, a failure of the Cisco SCE8000 does not affect the traffic flow, as the traffic continues to flow through the optical splitter.

• Internal Bypass Mechanism, page 3-9

• External Optical Bypass, page 3-9

Internal Bypass Mechanism

The Cisco SCE8000 includes a SPA Interface Processor module with a bypass mechanism that is enabled upon Cisco SCE8000 failure.

Link Continuity

The SPA Interface Processor card supports the following three 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 Cisco SCE8000 processes the

traffic for monitoring and control purposes.

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

functionality at layer 1).

The SPA Interface Processor card cannot preserve the link in the following circumstances:

• During platform reboot (SW reload), there is a 5-second period (at most) during which the link is

forced down (cutoff functionality).

• During a power failure (The Cisco SCE8000 has two power supplies. A power failure occurs only

when both of them fail).

• Under certain types of failure within the SIP module, the SPA cards, or the XFP optic modules.

External Optical Bypass

In installations in which the limitations of the internal bypass are not acceptable, an external optical bypass device can be used to provide dependable link continuity. The external optical bypass device can be installed either inside the Cisco SCE8000 chassis or be rack-mounted externally. The external optical bypass device can also be controlled manually by specific CLI commands.

OL-16478-02

Under normal operating conditions, traffic flows through the link as usual, with the exception that the optical bypass module sits on the link.

Chapter 3 Cisco SCE8000 Topology and Topology-Related Parameters

Topology-Related Parameters

Refer to the following sections to determine the correct values for all topology-related parameters before beginning to run the initial setup of the Cisco SCE8000.

• Connection Mode Parameter, page 3-11

• Physically Connected Links Parameter, page 3-12

• Priority, page 3-12

• On-Failure Mode Parameter, page 3-12

There are four topology-related parameters:

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

Cisco SCE8000 (Refer to Connection Mode Parameter, page 3-11):

–

Inline — single Cisco SCE8000 inline

–

Receive-only — single Cisco SCE8000 receive-only

–

Inline-cascade — two inline Cisco SCE8000 platforms cascaded

–

Receive-only-cascade — two receive-only Cisco SCE8000 platforms cascaded

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

link connected to the Cisco SCE8000 platform being configured. (Refer to Physically Connected

Links Parameter, page 3-12.)

Topology-Related Parameters

It is applicable only in a cascade topology.

• Priority — This parameter defines which is the primary Cisco SCE8000 (Refer to Priority,

page 3-12.)

It is applicable only in a cascade topology

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

Cisco SCE8000 either has failed or is booting. Traffic bypass can be achieved either through the external optical bypass device or through the internal bypass mechanism of the SPA interface processor. It is not applicable to receive-only topologies. (Refer to On-Failure Mode Parameter,

page 3-12.)

These parameters are configured via the connection-mode command.

Connection Mode Parameter

The connection mode parameter refers directly to the physical topology in which the Cisco SCE8000 is installed. The connection mode depends on two factors:

• Inline/Receive-only:

–

Inline — The Cisco SCE8000 resides on the data link between the subscriber side and the network side, thus both receiving and transmitting packets.

–

Receive-only — The Cisco SCE8000 does not reside physically on the data link. Data is forwarded to the Cisco SCE8000 via an external optical splitter. The Cisco SCE8000 itself receives only and does not transmit.

• Cascade — Indicates a two Cisco SCE8000 topology where the two Cisco SCE8000 platforms are

connected via the cascade ports.

OL-16478-02

Cisco SCE8000 Installation and Configuration Guide, Rel 3.1.7

3-11

Topology-Related Parameters

The connection mode parameter is determined by the physical deployment of the Cisco SCE8000, as follows:

• Single Cisco SCE8000 inline installation = Inline connection mode.

• Single Cisco SCE8000 optical splitter installation = Receive-only connection mode.

• Two-platform cascaded Cisco SCE8000 inline installation = Inline-cascade connection mode.

• Two-platform cascaded Cisco SCE8000 optical splitter installation = Receive-only-cascade

connection mode

Physically Connected Links Parameter

A cascade topology supports two traffic links. This parameter defines which link is connected to which Cisco SCE8000 platform. The links are designated as follows:

• Link 0

• Link 1

Chapter 3 Cisco SCE8000 Topology and Topology-Related Parameters

Priority

In a cascade topology, the user must define the priority of each Cisco SCE8000.

• Primary — The Primary Cisco SCE8000 is active by default

• Secondary — The Secondary Cisco SCE8000 is the default standby.

Note that these defaults apply only when both devices are started together. However, if the primary Cisco SCE8000 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

The on-failure mode parameter configures the action taken by a failed box when a failure is detected.

As described in the section Internal Bypass Mechanism, page 3-9, the SPA Interface Processor card supports three different modes. The Bypass and Cutoff modes are possible when the Cisco SCE8000 is not operational due to platform failure or boot. The Forwarding mode enables control of traffic flow and is not compatible with the non-operational status.

The following on-failure modes are possible:

• Bypass — The SPA interface card forwards traffic between the two ports of each link with no

intervention of the control application running in the Cisco SCE8000 platform. This is also known as 'electrical bypass'.

In a cascade setup, this allows the traffic of the link connected to the failed box to be passed to the active box for processing.

3-12

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

Layer1.

• External-bypass – The external optical bypass device is used to bypass traffic, maintaining link

continuity at all times.

Cisco SCE8000 Installation and Configuration Guide, Rel 3.1.7

OL-16478-02

Chapter 3 Cisco SCE8000 Topology and Topology-Related Parameters

In a single Cisco SCE8000 topology, the value of this parameter is determined by whether or not the link can be completely cut when the Cisco SCE8000 fails, or whether traffic flow should continue across the link in spite of platform failure. In the latter case, the External-bypass mode is the recommended setting, and is therefore the default value for the on-failure mode parameter.

In a dual cascaded Cisco SCE8000 topology, the default on-failure mode is Bypass, since it preserves full traffic processing functionality on both links in most single box failures (as long as the SPA interface card is functioning properly).

• Cutoff mode is suggested for the following:

–

Non-redundant inline topology if value-added services (such as security) are crucial and are more important than maintaining connectivity.

• Bypass mode is suggested for the following:

–

Non-redundant inline topology if connectivity is of high importance.

–

In redundant inline setups, if cutoff or traffic loss on a single link for a period of up to ten minutes (during a rare event of a SPA interface card failure) can be tolerated.

• External-bypass mode is suggested for the following:

–

Non-redundant inline topology if connectivity is crucial.

Asymmetric Routing Topology

–

Redundant inline setups, if connectivity is crucial. Note that when this mode is used, the link connected to the failed box is not serviced, and the other link operates with asymmetric routing functionality.

Asymmetric Routing Topology

In some Service Control deployments, asymmetrical routing occurs between potential service control insertion points. Asymmetrical routing can cause a situation in which the two directions of a bi-directional flow pass through different SCE platforms, resulting in each SCE platform seeing only one direction of the flow (either the inbound traffic or the outbound traffic).

This problem is typically solved by connecting the two SCE platforms in cascade mode (or through an MGSCP cluster), thereby making sure that both directions of a flow run through the same SCE platform. However, this is sometimes not feasible, due to the fact that the SCE platforms sharing the split flow are geographically remote (especially common upon peering insertion). In this type of scenario, the asymmetric routing solution enables the SCE platform to handle such traffic, allowing SCA BB to classify traffic based on a single direction and to apply basic reporting and global control features to uni-directional traffic.

Asymmetric Routing and Other Service Control Capabilities

Asymmetric routing can be combined with most other Service Control capabilities, however there are some exceptions.

OL-16478-02

Service Control capabilities that cannot be used in an asymmetric routing topology include the following:

• Subscriber redirect

• Subscriber notification

• Any kind of subscriber integration. (Use subscriber-less mode or anonymous subscriber mode

instead)

Chapter 4 Installing the Cisco SCE8000 Chassis

Preventing Electrostatic Discharge Damage

Electrostatic discharge (ESD) damage, which can occur when electronic cards or components are improperly handled, results in complete or intermittent failures. Port adapters and blades consist of printed circuit boards that are fixed in metal carriers. Electromagnetic interference (EMI) shielding and connectors are integral components of the carrier. Although the metal carrier helps to protect the board from ESD, use a preventive antistatic strap during handling.

Following are guidelines for preventing ESD damage:

• Always use an ESD wrist or ankle strap and ensure that it makes good skin contact.

• Connect the equipment end of the strap to an unfinished chassis surface.

• When installing a component, use any available ejector levers or captive installation screws to

properly seat the bus connectors in the backplane or midplane. These devices prevent accidental removal, provide proper grounding for the system, and help to ensure that bus connectors are properly seated.

• When removing a component, use any available ejector levers or captive installation screws to

release the bus connectors from the backplane or midplane.

• Handle carriers by available handles or edges only; avoid touching the printed circuit boards or

connectors.

• Place a removed component board-side-up on an antistatic surface or in a static shielding container.

If you plan to return the component to the factory, immediately place it in a static shielding container.

Preparing for Installation

• Avoid contact between the printed circuit boards and clothing. The wrist strap only protects

components from ESD voltages on the body; ESD voltages on clothing can still cause damage.

• Never attempt to remove the printed circuit board from the metal carrier.

Caution For safety, periodically check the resistance value of the antistatic strap. The measurement should be

between 1 and 10 megohm (Mohm).

Environmental Requirements

Ensure adequate spacing between racks using the information in the following table. Keep all of the vents clear of obstructions, including dust and foreign conductive material, and away from the exhaust ports of other equipment.

• The redundant power configuration provides a second, identical power supply to ensure that power

to the chassis continues uninterrupted if one power supply fails or input power on one line fails.

• Connect each of the two power supplies to a separate input power source. If you fail to do this, your

system might be susceptible to total power failure due to a fault in the external wiring or a tripped circuit breaker.

• To prevent a loss of input power, be sure that the total maximum load on each circuit supplying the

power supplies is within the current ratings of the wiring and breakers.

• In some systems, you might use an uninterruptible power supply (UPS) to protect against power

failures at your site. Avoid UPS types that use ferroresonant technology. These UPS types can become unstable with systems like the Cisco SCE8000, which can have substantial current draw fluctuations due to bursty data traffic patterns.

Power Connection Guidelines

This section provides the guidelines for connecting the Cisco SCE8000 AC and DC power supplies to the site power source.

Chapter 4 Installing the Cisco SCE8000 Chassis

• AC-Powered Systems, page 4-4

• DC-Powered Systems, page 4-10

• Site Planning Checklist, page 4-11

AC-Powered Systems

• Each chassis power supply should have its own dedicated branch circuit.

• The circuit must be protected by a dedicated two-pole circuit breaker.

For North America, the circuit breaker should be rated at 20A.

For everywhere else, the circuit breaker should be sized according to the power supply input rating and local or national code requirements.

• The AC power receptacles used to plug in the chassis must be the grounding type. The grounding

conductors that connect to the receptacles should connect to protective earth ground at the service equipment.

Warning

Never defeat the ground conductor or operate the equipment in the absence of a suitably installed ground conductor. Contact the appropriate electrical inspection authority or an electrician if you are uncertain that suitable grounding is available.

DC-Powered Systems

Basic guidelines for DC-powered systems include the following:

• Each chassis power supply should have its own dedicated input power source. The source must

comply with the safety extra-low voltage (SELV) requirements in the UL 60950, CSA 60950, EN 60950, IEC 60950 standards.

• The DC supplies each have the provision for a dual connection to the power source in order to permit

high-power operation without exceeding current ratings. For the SCE8000, it is not necessary to connect both of these inputs to DC power sources; it is sufficient to connect only the '1' connections.

• Each circuit must be protected by a dedicated two-pole circuit breaker. The circuit breaker should

be sized according to the power supply input rating and local or national code requirements.

Chapter 4 Installing the Cisco SCE8000 Chassis

• The circuit breaker is considered the disconnect device and should be easily accessible.

• The system ground is the power supply and chassis ground.

Caution Do not connect the DC-return wire to the system frame or to the system grounding equipment.

Even if you will be managing the Cisco SCE8000 from a remote location, you must first connect the unit to a local console and configure the initial settings for the Cisco SCE8000 to support remote management. When the initial connection is established, the setup utility will run automatically, prompting you to perform the initial system configuration.

This section provides instructions for setting up your local terminal at your workstation, to enable you to perform the initial system configuration of the Cisco SCE8000 system using the setup utility.

Make sure that the terminal configuration is as follows:

• 9600 baud

• 8 data bits

• No Parity

• 1 stop bits

• No flow control

The above Cisco SCE8000 port parameters are fixed and are not configurable.

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 or DB-25 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 Cisco SCE8000

CON port parameters.

Step 4 Make sure that the Cisco SCE8000 is powered-on, and has been allowed to complete booting (this

process may take several minutes).

Step 5 Press Enter several times until the Cisco logo appears on the local terminal.

Initial Setup Parameters

At this point there are several basic global parameters that must be correctly configured in order for the SCE platform to communicate properly with the outside world. The following is a very brief summary of the initial setup parameters and commands. For more information, refer to the Cisco SCE8000

Software Configuration Guide.

• IP address and subnet mask of the Cisco SCE8000 platform itself. This is the IP address used by the

GBE management interface.

• IP address of the default gateway.

• Hostname—The hostname is used to identify the SCE platform. It appears as part of the CLI prompt

and is also returned as the value of the MIB-II object sysName.

Connecting the Management Interface

The SCE8000-SCM-E is equipped with one active RJ-45 management port. This port provides access from a remote management console to the Cisco SCE8000 via a LAN.

The procedures for cabling the GBE management port and testing connectivity between the Cisco SCE8000 and the remote management host are explained in the following sections.

• How to Cable the Management Port, page 5-4

• How to Verify Management Interface Connectivity, page 5-5

How to Cable the Management Port

The SCE8000-SCM-E has one GBE port that is used as the management port, located in slot# 1 of the Cisco SCE8000 chassis, and labeled Port1.

Step 1 Plug the Ethernet cable provided (with attached RJ-45 connector) into Port 1on the front panel of the

SCE8000-SCM-E. (See item #3 in Figure 5-2 below.)

Chapter 5 Connecting the Management Interfaces

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

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 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 Link LED 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 Cisco SCE8000 platform has been powered up, test now to verify that connectivity has been established between the Cisco SCE8000 and the remote management host. If the Cisco SCE8000 platform is not powered up, perform this step after starting the Cisco SCE8000 platform.

Connecting the Management Interface

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

port LEDS.

There are two GBE LEDs — Link/Active, and 10/100/1000 (refer to Service Control Module

(SCE8000-SCM-E), page 2-2).

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, as follows:

• Off: 10 Mbps

• Green: 100 Mbps

• Orange: 1000 Mbps

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

SCE8000 by typing ping and the Cisco SCE8000 IP address, and pressing Enter (see the example, below).

Note Note that only this step (Step 2), is performed from the remote management host (connected by LAN to

the Mng port).

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

The ping command 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.

Cabling the Line Ports and Completing the Installation

This chapter provides instructions for cabling the Cisco SCE8000 10 Gigabit Ethernet ports for single, cascaded, and MGSCP topologies. In a cascade topology, this includes the cascade ports as well as the line ports.

The 10 Gigabit Ethernet ports are located on the 10G SPA modules, which are installed in the SCE8000-SIP module in slot #3 of the Cisco SCE8000 chassis.

Note When installing a cascaded system, it is extremely important to follow the sequence of procedures

outlined in the section Cascaded Systems, page 6-15.

Note When installing an External Optical Bypass module, the Cisco SCE8000 line ports are connected to the

module. See Cabling the 10GBE Line Interface Ports: Using the External Optical Bypass Module,

page 6-11 for complete instructions.

Connecting the Line Ports to the Network

Single Link: Inline Topology

In the inline topology, the Cisco SCE8000 resides physically on the 10 GBE (Ten Gigabit Ethernet) link between the subscribers and the network. The subscribers 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). The network is a router or layer 3 switch network element connecting the Cisco SCE8000 towards the core of the network.

Guidelines for single link inline topologies

• If only two SPA modules are installed (only two SPA modules are required for a single link), they

must be installed in bays 0 and 1 of the SPA jacket card.

• Inline topologies require both Receive and Transmit fibers.

• To maintain link continuity at all times, an optical bypass module should be installed.

Single link inline connectivity

• Port 3/0/0: Link 0, Subscribers side

• Port 3/1/0: Link 0, Network side

Chapter 6 Cabling the Line Ports and Completing the Installation

Single Link: Receive-only Topology

In this topology, an optical splitter unit resides physically on the 10 GBE link that the Cisco SCE8000 should monitor. The optical splitter unit is connected to the Cisco SCE8000 Rx links only. For each link monitored, there will be two Rx connections to the Cisco SCE8000, one for each direction of traffic flow in the link. The traffic passes through the optical splitter, which allows the Cisco SCE8000 to monitor traffic without affecting the normal optic and data path between subscriber and network.

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.

Guidelines for single link receive-only topologies:

• If only two SPA modules are installed (only two SPA modules are required for a single link), they

must be installed in bays 0 and 1 of the SPA jacket card.

• Receive-only topologies use only Receive fibers.

Single link receive-only connectivity

• Port 3/0/0: Link 0, Split of optic signal transmitted by subscribers side

• Port 3/1/0: Link 0, Split of optic signal transmitted by network side

Dual Link: Single Cisco SCE8000 Topologies

6-2

In this topology, one Cisco SCE8000 is connected to two full duplex, 10GBE links. The Cisco SCE8000 may be either inline, to support both monitoring and traffic control functionality, or receive-only for traffic monitoring functionality only.

Guidelines for dual link topologies:

• SPA modules 0 and 1 are connected to the first link (Link 0)

• SPA modules 2 and 3 are connected to the second link (Link 1)

Cisco SCE8000 Installation and Configuration Guide, Rel 3.1.7

OL-16478-02

Chapter 6 Cabling the Line Ports and Completing the Installation

• Dual link inline topologies require both Receive and Transmit fibers.

• Dual link receive-only topologies use only Receive fibers.

• To maintain link continuity at all times on both links when using the inline topology, two optical

bypass modules should be installed.

Dual link connectivity

• Port 3/0/0: Link 0, Subscribers side

• Port 3/1/0: Link 0, Network side

• Port 3/2/0: Link 1, Subscribers side

• Port 3/3/0: Link 1, Network side

Note Receive-only topologies can be implemented using either an optical splitter or a switch. If a switch is

used, it must support SPAN functionality that includes separation between ingress and egress traffic and multiple SPAN-ports destinations.

Dual Link: Two Cisco SCE8000s Topology

Connecting the Line Ports to the Network

In this topology, two Cisco SCE8000s are connected to two full duplex, 10GBE links, providing full redundancy through cascading the two Cisco SCE8000s. The Cisco SCE8000s must be inline.

Note When installing a cascaded system, it is extremely important to follow the sequence of procedures

outlined in Cascaded Systems, page 6-15.

When two Cisco SCE8000s are used, the ports 3/0/0 and 3/1/0 in each Cisco SCE8000 are connected to the links, while ports 3/2/0 and 3/3/0 are the cascade ports that are used for communicating between the two Cisco SCE8000s as follows:

Cisco SCE8000 #1

• Port 3/0/0: Link 0, Subscribers side

• Port 3/1/0: Link 0, Network side

• Port 3/2/0: Cascade, connect to Port 3/3/0 in Cisco SCE8000 #2

• Port 3/3/0: Cascade, connect to Port 3/2/0 in Cisco SCE8000 #2

Cisco SCE8000 #2

• Port 3/0/0: Link 1, Subscribers side

• Port 3/1/0: Link 1, Network side

• Port 3/2/0: Cascade, connect to Port 3/3/0 in Cisco SCE8000 #1

• Port 3/3/0: Cascade, connect to Port 3/2/0 in Cisco SCE8000 #1

OL-16478-02

Inline topologies require connecting both Receive and Transmit fibers to the Cisco SCE8000. Cascade ports always require both Receive and Transmit fibers to be connected.

To maintain link continuity at all times, two optical bypass modules should be installed and the traffic ports should be connected to these bypass modules.

Chapter 6 Cabling the Line Ports and Completing the Installation

Connecting the Line Ports to the Network

Multi-Gigabit Service Control Platforms (MGSCP) Topologies

In this topology, multiple Cisco SCE 8000 platforms are connected to a Cisco 7600 Series router used as a load-balancer (“dispatcher”) between the platforms. Traffic enters the router, is distributed between the Cisco SCE8000 platforms by the router EtherChannel, and returns to the router to be forwarded to its original destination.

General guidelines for MGSCP topologies:

• Since there are two links per Cisco SCE8000 platform, the minimum number of platforms required

is half the number of links used.

• Each link corresponds to one port on the EtherChannel (EC) on the Cisco 7600 Series router. Each

EC supports a maximum of eight active ports. Therefore, if all eight EC ports are configured, four Cisco SCE8000 platforms are required.

• For N+1 redundancy, two additional ports (connected to the standby platform) must be configured

as standby ports on both ECs.

Therefore, for N+1 redundancy, one router and five Cisco SCE8000 platforms would be used to support eight links.

• If two Cisco 7600 Series routers are used (for network redundancy), one link on each Cisco

SCE8000 platform is connected to each router. This requires twice the number of Cisco SCE8000 platforms, one platform for each link.

–

A minimum of eight Cisco SCE8000 platforms are required to support eight ports.

–

For N+1 redundancy, nine Cisco SCE8000 platforms would be used to support eight active links

When cabling to the EC, follow these guidelines:

• The Cisco SCE platform ports MUST be connected to the EC ports in the same order on both sides.

• The EC ports should be sorted in an ascending order by their physical interface numbers.

• In a topology with two Cisco 7600 Series routers, the order of connection to the EC ports must be

the same on both routers. In order for both routers to send the traffic of a given subscriber to the same SCE platform, the SCE platforms must be connected to both routers in exactly the same order (one SCE platform connected to the first link on both routers, another SCE platform connected to the second link on both routers, and so on).

• Refer to MGSCP Connectivity Examples, page 6-4 for specific examples explaining how to connect

the Cisco SCE8000 ports to the EC ports in various topologies.

• Refer to Dual Link: Single Cisco SCE8000 Topologies, page 6-2 and Single Link: Inline Topology,

page 6-2 for further information on specific cabling schemes.

The First Step-Ordering the EC Ports

This section explains how to order the EC ports and assign them to links. This example is the basis for all following examples.

1. Sort the EC ports in an ascending order by their physical interface numbers. Take the following EC

interfaces as an example:

–

EC1 (subscriber side): 0/1, 0/2, 1/3, 1/5

–

EC2 (network side): 2/2, 3/1, 3/2, 3/4

2. Order the ports in subscriber/network pairs according to their order in the ECs (the first port in EC1

(subscriber side) is paired with the first port in EC2 (network side) and so on):

–

Link 1. S=0/1, N=2/2

–

Link 2. S=0/2, N=3/1

–

Link 3. S=1/3, N=3/2

–

Link 4. S=1/5, N=3/4

Single Router MGSCP Connectivity

Four links would require two Cisco SCE8000 platforms. Connect the ordered pairs, each pair of EC ports to a pair of Subscriber/Network ports in a Cisco SCE8000 platform:

Connecting the Line Ports to the Network

• Cisco SCE8000 #1: Links 1 and 2

• Cisco SCE8000 #2: Links 3 and 4

The actual connections might look like this:

• S=0/1, Cisco SCE8000 #1 3/0/0

• N=2/2, Cisco SCE8000 #1 3/1/0

• S=0/2, Cisco SCE8000 #1 3/2/0

• N=3/1, Cisco SCE8000 #1 3/3/0

• S=1/3, Cisco SCE8000 #2 3/0/0

• N=3/2, Cisco SCE8000 #2 3/1/0

• S=1/5, Cisco SCE8000 #2 3/2/0

• N=3/4, Cisco SCE8000 #2 3/3/0

Single Router with N+1 Redundancy MGSCP Connectivity

In order to have N+1 redundancy, we must add one extra SCE platform as the standby platform. We also must add two more ports on each EC to be used as standby ports. In this case, we would use three SCE platforms, two on the traffic links and one for redundancy, which would be connected to the standby ports.

If we added ports 0/3 and 2/3 on EC1 and 2/4 and 4/4 on EC2, the ECs would look like this:

• EC1: 0/1, 0/2, 0/3, 1/3, 1/5, 2/3

• EC2: 2/2, 2/4, 3/1, 3/2, 3/4, 4/4

OL-16478-02

The standby ports must be the two highest-numbered ports:

• EC1 standby ports: 1/5, 2/3

• EC2 standby ports: 3/4, 4/4

The traffic ports would be assigned to the links as follows:

Cisco SCE8000 Installation and Configuration Guide, Rel 3.1.7

Connecting the Line Ports to the Network

• Link 1. S=0/1, N=2/2

• Link 2. S=0/2, N=2/4

• Link 3. S=0/3, N=3/1

• Link 4. S=1/3, N=3/2

The standby ports would be assigned to the links as follows:

• Link 5 (standby). S=1/5, N=3/4

• Link 6 (standby). S= 2/3, N=4/4

If Cisco SCE8000 #3 is the redundant platform, Links 5 &6 would be connected to it and the actual connections might look like this:

• S=0/1, Cisco SCE8000 #1 3/0/0

• N=2/2, Cisco SCE8000 #1 3/1/0

• S=0/2, Cisco SCE8000 #1 3/2/0

• N=2/4, Cisco SCE8000 #1 3/3/0

• S=2/3, Cisco SCE8000 #3 3/2/0

• N=4/4, Cisco SCE8000 #3 3/3/0

Dual Routers MGSCP Connectivity

Four links on each router would require four Cisco SCE8000 platforms. For the sake of simplicity, we assume that the EC ports are the same on both routers.

Connect the ordered pairs, each pair of EC ports to a pair of Subscriber/Network ports in a Cisco SCE8000 platform:

• Cisco SCE8000 #1: Link 1 on both routers

• Cisco SCE8000 #2: Link 2 on both routers

• Cisco SCE8000 #3: Link 3 on both routers

• Cisco SCE8000 #4: Link 4 on both routers

Dual Routers with N+1 Redundancy MGSCP Connectivity

In order to have N+1 redundancy, we must add one extra SCE platform as the standby platform. We also must add another port on each EC to be used as standby ports. In this case, we would use five SCE platforms, four on the traffic links and one for redundancy, which would be connected to the standby ports.

Again, for the sake of simplicity, we assume that the EC ports are the same on both routers.

If we added ports 0/3 on EC1 and 2/4 on EC2, the ECs would look like this:

Connecting the Line Ports to the Network

• EC1: 0/1, 0/2, 0/3, 1/3, 1/5

• EC2: 2/2, 2/4, 3/1, 3/2, 3/4

The standby ports must be the highest-numbered ports:

• EC1 standby port: 1/5

• EC2 standby port: 3/4

The traffic ports would be assigned to the links as follows:

• Link 1. S=0/1, N=2/2

• Link 2. S=0/2, N=2/4

• Link 3. S=0/3, N=3/1

• Link 4. S=1/3, N=3/2

The standby ports would be assigned to the links as follows:

The Optical Bypass Module

Chapter 6 Cabling the Line Ports and Completing the Installation

The external optical bypass module is an optional component that provides additional protection by enabling automatic preservation of the network 10GBE link. For more information regarding the external bypass module, refer to The Cisco SCE8000 Optical Bypass, page 2-8.

There are two installation options for the optical bypass module:

• Chassis mount—The optical bypass module may be installed in the panel in slot #4 of the Cisco

SCE8000 chassis. This panel hosts up to two optical bypass modules.

• External mounting panel: —The optical bypass module may be installed in a panel that is mounted

in a 19" rack. This panel can host up to four optical bypass modules.

Note Make sure to use the correct type of optical bypass module (single-mode or multi-mode) according to

the transceivers and cabling that are used for the subscriber and network links.

Note Since the optic bypass module will directly connect the subscriber and network side optic paths when

bypassing the SCE8000, the subscriber and network optic links must be of the same type (single-mode or multi-mode) and wavelength.

Warning

Invisible laser radiation may be emitted from disconnected fibers or connectors. Avoid exposure to radiation and do not stare into open aperture.

Optical Device Maintenance

Any contamination of the fiber connection can cause failure of the component or failure of the whole system. A particle that partially or completely blocks the core generates strong back reflections, which can cause instability in the laser system. Inspection, cleaning, and reinspection are critical steps to take before making fiber-optic connections.

How to Cable the 10GBE Line Interface Ports

Step 1 Take the appropriate fiber optic cable (see Fiber Specifications, page 6-10) and plug it into the

appropriate port on the 10GBE interface on the SPA module in slot #3 of the Cisco SCE8000. (See

Figure 6-1 below.)

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.

Step 2 Using a cable with LC connectors on both ends, plug one end into the appropriate port (C or D) on the

external bypass module and the other end into the appropriate 10GBE interface in slot #3 of the SCE8000 chassis.

Step 3 Using the control cable provided, which has RJ11 connectors on both ends, plug one end into the CNTRL

interface on the external bypass module (see Figure 6-3) and plug the other end into the External Bypass interface on the SCE8000-SCM-E in slot #1 of the SCE8000 chassis (see item #1 in Figure 6-4 below). If using only one external bypass module, use External Bypass port #1. If using two external bypass modules, use both External Bypass ports on the SCE8000-SCM-E in slot #1.

Step 4 Complete the installation and powering up of the SCE8000.

By its nature, the optic bypass module will not connect the link to the SCE8000-SIP module until the entire SCE8000 system is fully functional. It is necessary to bring the SCE8000 to fully operational, non-bypassed status, in order to confirm correct functioning of the link through the optic bypass module to the SCE8000-SIP module.

Step 5 Verify link connectivity by checking that the link LED on the 10GBE interface is green, or by using the

SCE8000 command line.

• How to View the User Log Counters, page 6-14

Examining the LEDs

The 10GBE Link LED should be green, verifying that an active connection exists.

How to View the Ten Gigabit Ethernet Port Status

Cabling the 10GBE Line Interface Ports

Step 1 At the Cisco SCE8000# prompt, type show interface TenGigabitEthernet 3/ baynumber /0.

This displays the port link status.

The following example displays a system response.

Cisco SCE8000#show interface TenGigabitEthernet 3/1/0 Actual Status: Link is on Bandwidth: 10000000Kbps Burst-size: 500000bytes

How to View the Ten Gigabit Ethernet Counters

In an inline topology, you can monitor traffic via the platform counters for both the Rx and Tx connections. The counters increase as packets flow through the Cisco SCE8000 for both Rx and Tx.

However, in receive-only topologies, the counters for the Tx do not increment, as the SCE8000 is only monitoring traffic, and not re-transmitting it

Step 1 At the Cisco SCE8000# prompt, type show interface TenGigabitEthernet 3/ baynumber /0 counters.

This displays the TenGigabitEthernet counters. This command enables you to verify that traffic is taking place. You can see that the counters increase, together with real-time packet flow through the Cisco SCE8000.

Remember, in bump-in-the-wire topology, both the Rx and Tx counters apply as traffic monitors. For receive-only topologies, using an external splitter, only the Rx counters apply.

Cascaded Systems

• How to Install a Cascaded System, page 6-15

• CLI Commands for Cascaded Systems, page 6-16

How to Install a Cascaded System

This section outlines the installation procedures for a redundant solution with two cascaded Cisco SCE8000 platforms. Refer to the Cisco Service Control Engine (SCE) CLI Command Reference for details of the CLI commands.

When working with two Cisco SCE8000 platforms with split-flow and redundancy, it is extremely important to follow this installation procedure.

Step 1 Install both Cisco SCE8000 platforms, power them up, and perform the initial system configuration. (See

Chapter 4, “Installing the Cisco SCE8000 Chassis”and Chapter 5, “Connecting the Management Interfaces”and Starting the Cisco SCE8000 Platform, page 7-1.)

Cascaded Systems

To maintain link continuity at all times, including during the reload sequence and power failure events, optical bypass modules must be installed.

Step 2 Connect both Cisco SCE8000 platforms to the management station. (See Connecting the Management

Interface, page 5-4.)

Step 3 Connect the cascade ports. (See Dual Link: Two Cisco SCE8000s Topology, page 6-3.)

The cascade ports must be either be connected directly in Layer 1 (dark fibers), or using the following procedure to connect through a switch.

• Connect port 3/2/0 from box A and port 3/3/0 from box B to a single switch. Configure them both

on the same access VLAN, which will be used only by the interfaces connected to these ports. No other interfaces in the switch should reside on that VLAN.

• Connect port 3/3/0 from box A and port 3/2/0 of box B to a switch on a different VLAN. Again, the

access ports should be configured as access ports on this VLAN, which will be used only by the interfaces connected to these ports. No other interfaces in the switch reside on the VLAN.

Step 4 Set topology configurations for each Cisco SCE8000 platform via the connection-mode options. (See

How to Configure the Connection Mode, page 6-16.)

Step 5 Make sure that the Cisco SCE8000 platforms have synchronized and active Cisco SCE8000 platform was

selected.

Use the show interface linecard 0 connection-mode command.

Step 6 If you want to start with bypass, change the link mode to your required mode in both Cisco SCE8000

platforms on both links. The bypass mode will be applied only to the active Cisco SCE8000 platform. (See How to Set the Link Mode, page 6-17.)

OL-16478-02

Step 7 Make sure that the link mode is as you required. (See Monitoring the System, page 6-18.)

Use the show interface linecard 0 link mode command.

Step 8 Connect the traffic port of Cisco SCE8000 platform #1. This will cause a momentary down time until

the network elements from both sides of the Cisco SCE8000 platform auto-negotiate with it and start working (when working inline). (See Dual Link: Two Cisco SCE8000s Topology, page 6-3.)

Cisco SCE8000 Installation and Configuration Guide, Rel 3.1.7

6-15

Cascaded Systems

Step 9 Connect the traffic port of Cisco SCE8000 platform #2. This will cause a momentary down time until

the network elements from both sides of the Cisco SCE8000 platform auto-negotiate with it and start working (when working inline). (See Dual Link: Two Cisco SCE8000s Topology, page 6-3.)

Step 10 When full control is needed, change the link mode on both Cisco SCE8000 platforms on both links to

‘forwarding’. It is recommended to first configure the active Cisco SCE8000 platform and then the standby. (See How to Set the Link Mode, page 6-17.)

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

• show interface linecard 0 connection-mode

Chapter 6 Cabling the Line Ports and Completing the Installation

• show interface linecard 0 physically-connected links

• Topology-Related Parameters for Redundant Topologies, page 6-16

• How to Configure the Connection Mode, page 6-16

• How to Set the Link Mode, page 6-17

• Monitoring the System, page 6-18

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 is:

–

Inline-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 via an external optical bypass module when the SCE platform either has failed or is booting.

If either the bypass or external-bypass option is configured, the optical bypass module must be properly installed. If an optical bypass device is not detected, the command is executed but a warning is issued. The system then enters warning mode until either the command is changed, or the presence of an optical bypass device is detected

How to Configure the Connection Mode

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

Cisco SCE8000 Installation and Configuration Guide, Rel 3.1.7

6-16

OL-16478-02

Chapter 6 Cabling the Line Ports and Completing the Installation

• inline

• physically connected links

• behavior upon failure of the SCE platform

• primary/secondary

Step 1 From the Cisco SCE8000(config if)# prompt, type connection-mode inline-cascade

physically-connected-links (link-0|link-1) priority (primary|secondary) on-failure (external-bypass|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.

Cisco SCE8000(config if)# connection-mode inline-cascade physically-connected-links link-1 priority primary on-failure bypass

Cascaded Systems

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.

Cisco SCE8000(config if)# connection-mode inline-cascade physically-connected-links link-0 priority secondary on-failure bypass

How to Set the 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 three possible modes of operation:

• bypass

• forwarding

• cutoff

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.

OL-16478-02

• 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.

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

Note the following recommendations and restrictions:

Cisco SCE8000 Installation and Configuration Guide, Rel 3.1.7

6-17

Cascaded Systems

• Link mode is relevant only to inline topologies.

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

mode, otherwise the service will be unpredictable.

• 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.

Step 1 From the Cisco SCE8000 (config if)# prompt, type link mode [forwarding|bypass|cutoff] and press

Enter.

After reboot, the SCE platform loads the startup-config, which includes the non-default configuration that was saved by the user, into the running-config.

The SCE platform provides commands for:

• Viewing the running configuration with only user-configured (non-default) values: show

running-config

• Viewing the running configuration with all the SCE platform running configuration values, whether

default or not: show running-config all-data

• Viewing the startup configuration: show startup-config

After configuring the SCE platform, you may query for the running configuration using the command show running-config.

Step 1 At the Cisco SCE8000# prompt, type show running-config.

The system shows the running configuration.

Saving or Changing the Configuration Settings

When you make changes to the current running configuration and you want those changes to continue to be in effect when the system restarts, you must save the changes before leaving the management session. You do that by saving the running configuration to the startup configuration file.

The SCE platform provides multiple interfaces for the purpose of configuration and management. All interfaces supply an API to the same database of the SCE platform and any configuration made through one interface is reflected through all interfaces. Furthermore, when saving the running configuration to the startup configuration from any management interface, all configuration settings are saved regardless of the management interface used to set the configuration.

For backup purposes, the old startup-config file is saved under the directory: to Restoring a Previous Configuration, page 7-8 for an explanation on how to restore a previous configuration.

To remove a configuration command from the running-config, use the no form of the command.

Step 1 At the SCE# prompt, type show running-config to view the running configuration.

The running configuration is displayed.

Step 2 Check the displayed configuration to make sure that it is set the way you want. If not, make the changes

you want before saving.

Step 3 Type copy running-config startup-config.

The system saves all running configuration information to the configuration file, which is used when the system reboots.

The configuration file holds all information that is different from the system default in a file called config.tx1 located in the directory: /system.

Example for Saving or Changing the Configuration Settings

The following example shows how to save the running configuration file (first displaying the file to review the settings).

Restoring a Previous Configuration

Chapter 7 Basic Cisco SCE8000 Platform Operations

When you save a new configuration, the system automatically backs up the old configuration in the directory

config.tx1-config.tx9, where config.tx1 is the most recently saved file.

/system/prevconf/. Up to nine versions of the startup configuration file are saved, namely

You can view the old startup configuration files using the CLI command more.

Restoring a previous startup configuration means renaming the file so it overwrites the startup configuration (

Step 1 At the SCE# prompt, type more /system/prevconf/config.tx1 to view the configuration file.

config.txt) file.

The system displays the configuration information stored in the file.

Step 2 Read the configuration information to make sure it is the configuration you want to restore.

Note that you cannot undo the configuration restore command.

Step 3 Type copy /system/config.tx1 /system/config.txt.

The system sets the startup configuration to the configuration from config.tx1.

Example for Restoring a Previous Configuration

The following example displays a saved configuration file and then restores the file to overwrite the current configuration.
