Cisco Multiservice Broadband Cable Guide
OVERVIEW
Overview
Cisco Multiservice Broadband Cable Guide
Purpose and Scope
Cisco Systems offers a complete portfolio of standards-based cable products,
solutions, and network management systems that enable integration of data, voice,
and video services on a single multiservice cable Internet Protocol (IP) network.
Cable service providers can look to Cisco to deliver flexible, scalable, and
cost-effective choices that extend from a cable headend or distribution hub, regional
core or data center, all the way to the subscriber. With Cisco, cable service providers
can expand their services, diversify their revenue streams, and become more
competitive and successful.
The Cisco Multiservice Broadband Cable Guide describes the Cisco products used to
build the next generation cable IP network. This guide is intended for Cisco cable
service providers, partners, resellers, and sales account teams that need a broad,
high-level overview of Cisco cable products, solutions, network management
systems, and programs.
Given the breadth of the Cisco offering and our continual innovations, there are
likely to be new products, solutions, and programs not included when this guide was
published. For up-to-date information, please refer to
www.cisco.com/warp/public/779/servpro/solutions/cable/
or consult a Cisco representative.
Cisco Cable Offering
Cisco delivers the end-to-end products, solutions, and network management systems
that give cable service providers demonstrable return on investment. We bring
intelligence to the network. Only Cisco has the offering and expertise to build
large-scale, multiservice cable IP networks. Leveraging the rich set of Cisco products
and solutions, cable service providers can seamlessly integrate new technologies and

services, increase revenue with effective incremental investment, and offer more
services over the same cable IP infrastructure. The following figure illustrates a large
multiservice cable IP network:
ix
Cisco Multiservice Broadband Cable Guide
Overview
OVERVIEW
IP has become the service convergence protocol of choice for business and residential
customers. Flexible and media-independent, IP networking contains robust control
mechanisms that lend themselves well to multiservice networking.
Cable service providers are uniquely positioned to rapidly deploy and sell
leading-edge IP services because they own and control both the high-bandwidth
infrastructures and the services sent across them. Internet service providers (ISPs) and
telephone companies do not enjoy this built-in, ready-to-go advantage. With control
over both infrastructure and service delivery, cable companies are strongly
positioned to rapidly provision and deploy leading-edge IP services less expensively
than time division multiplexed (TDM)-based providers. Cable service providers can
use the same cable plant to deliver data, voice, and video services, and the same
network management systems to provision and operate them. The per-port cost of
provisioning voice-over-IP (VoIP) service is dramatically lower than public switched
telephone network (PSTN) service. The result is cable service providers and their
customers have greater flexibility, integration, and control over services.
Consolidating data, voice, and video capabilities onto a single cable infrastructure is
just the beginning. The true promise of multiservice networking is the integration of
data, voice, and video into powerful new applications. With Cisco, cable service
providers can translate the promise of multiservice networking into profitable
services today. Cable service providers can develop and deploy network architectures
that last. They can build architectures that:
• Scale to handle growth in devices, ports, and bandwidth capacity
• Accommodate services today, as well as future innovative services
• Offer high availability—99.999% up time
• Administer bandwidth and services management through quality of service (QoS)
which dynamically allocates bandwidth as needed for optimal efficiency and
committed access rates (CAR) which rate-limit bandwidth on a per user basis
• Provide security through reverse path forwarding (RPF) checks which prevent
denial-of-service attacks and through access control lists (ACL) which control
user access permission to the network
• Support high transport technologies such as Dynamic Packet Transport (DPT)
and Resilient Packet Rings (RPR), wave division multiplexing (WDM),
synchronous optical network (SONET) / synchronous digital hierarchy (SDH)
Overview

Overview
The figure below positions respective products:
Cable Line Cards
Cisco provides a full set of cable line cards that interface the cable plant. The line
cards support DOCSIS and EuroDOCSIS error correction encoding, modulation
types, and formats. Policy-based and dynamic spectrum management features are
offered. The cards give service providers differing downstream and upstream signal
combining and splitting options.
1-3
Overview
Chapter 1 CMTS Systems
CHAPTER 1 CMTS SYSTEMS
The table below identifies line cards:
Cisco was the first to introduce a line card that integrates a DOCSIS-qualified cable
interface with an onboard spectrum analyzer. This card—the Cisco uBR-MC16S—
maximizes spectrum utilization, improves response time to ingress and noise impairments,
and provides intelligent “look ahead” capability to hop to a new center frequency in clear
spectrum. The card increases cable plant availability and reduces reliance on costly
spectrum analyzers at every headend or hub.
Cisco developed and introduced the industry’s highest-density line card. Offering a
total of two downstream and eight upstream ports each, the Cisco uBR-MC28C and
Cisco uBR-MC28C-BNC significantly increase the number of subscribers a Cisco
uBR7246VXR, Cisco uBR7223, or Cisco uBR10012 can support. Deploying
advanced cable IP services means cable operators must be able to scale network
bandwidth and support large numbers of subscribers efficiently and cost-effectively.
The Cisco uBR-MC28C and Cisco uBR-MC28C-BNC line cards meet these needs.
Network Interfaces
Cisco Universal Broadband Routers offer a broad choice of network interfaces, allowing
network-layer capabilities to be extended to a wide range of network configurations and
environments. Most of the common LAN and WAN technologies are supported, such as:
• Ethernet, Fast Ethernet, Gigabit Ethernet
• Serial (T1/E1 and T3/E3)

Overview
Integrating advanced digital video functionality into its offering, the Cisco 6920
RateMUX® is the first in a series of Cisco products designed to allow cable service
providers to maximize bandwidth efficiency and distribution of digital video. The
Cisco 6920 RateMUX combines digital programming from a variety of sources into
a single, multiplexed optimized MPEG transport stream for distribution over an
HFC cable network. The product provides advanced MPEG-2 stream manipulation
including real-time bit-rate manipulation, splicing, statistical multiplexing, and
customized channel line ups.
The Cisco 6920 RateMUX supports:
–Grooming of digital program lineups—Operators are able to customize local
channel lineups from a variety of sources to align their services with the
preferences of their subscriber base
–Enhanced television—Electronic program guides and other “interactive” data
can be multiplexed into the MPEG transport for use by the set-top box (STB)
–HDTV service—The Cisco 6920 RateMUX can multiplex in HDTV with
statistically multiplexed SDTV programs to maximize the HDTV’s output
transport

Cisco 6920 RateMUX Advanced MPEG-2
Multiplexer
The Cisco 6920 RateMUX® is an advanced
Moving Pictures Experts Group (MPEG)
multiplexing device that assists cable operators in
creating customized digital program lineups. The product extends the life of existing
cable plant and set-top equipment by providing a smooth migration path to new
digital services such as “enhanced” television and HDTV. The Cisco 6920 RateMUX
aggregates or multiplexes the digital program streams from satellite receivers and
local encoders and produces standard MPEG-2 transports which are exported to
conditional access (CA)/quadrature amplitude modulation (QAM) devices for
distribution through the cable RF plant.
The Cisco 6920 RateMUX accepts discrete MPEG-2 input through interfaces
compliant with Digital Headend Interface (DHEI) or Digital Video
Broadcasting-Asynchronous Serial Interface (DVB-ASI) standards. It then uses a
powerful digital signal processor (DSP) engine to produce MPEG-compliant
transport streams that have been optimized (statistically multiplexed) through the
use of intelligent buffer management and selective bit rate reduction during bit rate
peaks.

IP Telephony
Overview
With access to a vast number of households, cable operators are in an excellent
position to offer residential IP telephony services. Experienced in building both
robust IP telephony networks and cable architectures, Cisco has the expertise and
products to build end-to-end Cable VoIP networks. Cisco is a vital contributor to
CableLab’s PacketCable specification designed to seamlessly integrate cable and
telephony products over DOCSIS-based networks.
PacketCable-compliant networks use Multimedia Gateway Control Protocol
Network-based Call Signaling (MGCP-NCS) to provide centralized call control
via an intelligent call agent. To allow seamless mixing of voice, video, and data
in a unified data stream, the HFC plant should meet DOCSIS 1.1 specifications.
DOCSIS 1.1 offers enhanced Quality of Service (QoS) features that give priority
for real-time traffic such as voice and video.
Key components of a multiservice cable IP network include:
• The Cisco uBR10012 or Cisco uBR7246VXR Universal Broadband Router that
provide multiple functions in the architecture including Dynamic Quality of
Service (DQoS), event messaging and security
• Multimedia Terminal Adapters (MTAs) located at subscriber residences that
communicate with the Cisco uBR7246VXR or Cisco uBR10012
• The Cisco BTS 10200 Softswitch that provides call-control intelligence for
establishing, maintaining, routing, and terminating voice calls; it also serves as an
interface to enhanced, converged voice-and-data services and application platforms
such as voice mail and unified messaging
• Media gateways, also called trunking gateways, that provide connectivity to the PSTN
• Cisco Broadband Provisioning Registrar that provisions telephony service
Chapter 4 IP Telephony
4-2
Overview
Cisco partners with third-party vendors to provide other media and billing mediation
services that comprise an end-to-end IP telephony solution. The provisioning
component in the telephony design not only includes standard DOCSIS provisioning
components such as DNS, DHCP, TFTP, and TOD servers, but also adds in a
Kerberos server for security. Provisioning and Kerberos servers act together to
provide a secure provisioning environment to provision vendor-independent CPE.
The media servers are add-on components that make the service offering more
robust. They add functionality on top of the architecture, providing services such as
lawful intercept requirements for CALEA; announcement and conference servers
such as voice mail. The record-keeping server is a billing mediation device that
collects events from various points in the network, collates them, and forms call
detail records for use by a billing system.

Cisco Cable-Ready Solutions at a Glance
Managed Access Cisco Cable-Ready Solution
To tap into the large high-speed data (HSD) market, ISPs are pushing to gain access
to HFC cable plants. Cable service providers stand to gain many operational and
scalability benefits from deploying a Managed Access Cisco Cable-Ready Solution.
Cable operators can position themselves to grow revenues, while supporting open
access. They can partition the cable plant and create scalable VPNs that support
varying QoS requirements for multiple ISPs and their subscribers. Cable companies
can give ISPs access to their HFC networks. ISPs can build value-added services on
top of the HFC infrastructure. Subscribers can select services from multiple service
providers. As subscribers team up with their preferred ISP and choose services from
multiple providers, loyalty increases. Incremental revenue opportunities develop a
more stable and wider customer base for cable companies.

Managed Access Cisco Cable-Ready Solution
Implementation choices include:
• Policy-based routing (PBR), which uses standard routing protocols to route a
packet based on the destination address
• Multiprotocol Label Switching (MPLS), which uses an innovative technique for
high-performance packet forwarding based on a label applied at the edge of an
MPLS domain.
When to Use
Choice Comparisons
PBR
PBR uses standard routing protocols to determine how to route a packet. Standard
routing is done based on the destination address of a packet With PBR, the routing
decision is based on the source address of the packet. Depending on the cable
operator’s objective, PBR can occur as the packet enters the network (ingress router
which is the CMTS), at an aggregation router, or as the packet leaves the network
(egress router). If the goal is to keep some traffic segregated from other traffic within
the cable operator’s network, PBR must be done on every router along the packet’s
path.
Use This Managed
Access Choice
When You Need
PBR • Faster rollout
• To use standard routing technology
MPLS • A more robust solution; Cisco recommends this approach
• Hard QoS guarantees
• Fast reroute for protection, resiliency, and reliability
Approach Strengths Weaknesses
PBR • Quicker time to deploy • PC-assigned commercial customer address
by cable operator provisioning system
• Requires configuration and routing expertise
to ensure that both the cable operator and
ISP route packets properly in both directions
• Somewhat difficult to scale due to
complexities of management
MPLS • Provides virtual routing table
(one for each ISP)
• Full QoS and traffic engineering
available; new QoS/CoS revenue
opportunity
• Fast reroute for protection, resiliency,
and reliability
• Guaranteed bandwidth for hard QoS
guarantees
• Service-level agreements (SLAs)
• Requires MPLS on the entire backbone

Multiple Protocol Label Switching (MPLS)
MPLS is an innovative technique for high-performance packet forwarding. Using
MPLS VPN, service providers deliver IP services using Layer 3 QoS and a label-based
forwarding paradigm that ensures privacy. Labels indicate route and service
attributes. Cable operators build VPNs for ISPs to move traffic over their cable
plants. ISPs use the HFC network to supply service to their customers.

CHAPTER 6 ROUTERS
Cisco 10720 Internet Router
The Cisco 10720 Internet Router is a
high-performance router and a principle
building block in the metro IP network. It
enables service providers to offer innovative
and differentiated IP services to their customers at optical speeds. Equipped with
Ethernet technology for customer access and the innovative Dynamic Packet
Transport (DPT) technology for metro optical connectivity, the Cisco 10720 allows
service providers to offer IP services closer to the user, enabling them to better control
admission to network resources. This allows service providers to bypass traditional
DS1 and DS3 access options. The dual counter rotating ring technology of DPT is
also cost effective, since it uses both rings and can be deployed over dark fiber and
still maintain the less than 50ms restoration common in SONET/SDH systems. For
multiservice applications, DPT can also be deployed over traditional SONET/SDH
ADMs and wavelength division multiplexing (WDM) systems.
The Cisco 10720 is a cost-effective, reliable platform that not only supports the
full suite of IP routing protocols such as IS-IS, OSPF and BGP, but also allows
advanced IP features to be introduced efficiently, without compromising on
performance. Although primarily designed for high-speed Internet services for
multitenant and business-park applications in the metro, the Cisco 10720
Internet Router is also suitable for a range of other applications such as Internet
data center applications, cable multisystem operator (MSO) internetworking, and
voice-over-IP (VoIP) aggregation.

Cisco 10720 Internet Router
Chapter 7 Optical Transport
CHAPTER 7 OPTICAL
TRANSPORT
Cisco 10720 Internet Router
The Cisco 10720 Internet Router is a
high-performance router and a principle
building block in the metro IP network. It
enables service providers to offer innovative
and differentiated IP services to their customers at optical speeds. Equipped with
Ethernet technology for customer access and the innovative Dynamic Packet
Transport (DPT) technology for metro optical connectivity, the Cisco 10720 allows
service providers to offer IP services closer to the user, enabling them to better control
admission to network resources. This allows service providers to bypass traditional
DS1 and DS3 access options. The dual counter rotating ring technology of DPT is
also cost effective, since it uses both rings and can be deployed over dark fiber and
still maintain the less than 50ms restoration common in SONET/SDH systems. For
multiservice applications, DPT can also be deployed over traditional SONET/SDH
ADMs and wavelength division multiplexing (WDM) systems.
The Cisco 10720 is a cost-effective, reliable platform that not only supports the full
suite of IP routing protocols such as IS-IS, OSPF and BGP, but also allows advanced
IP features to be introduced efficiently, without compromising on performance.
Although primarily designed for high-speed Internet services for multitenant and
business-park applications in the metro, the Cisco 10720 Internet Router is also
suitable for a range of other applications such as Internet data center applications,
cable multisystem operator (MSO) internetworking, and voice-over-IP (VoIP)
aggregation.
When to Use
Use This Product When You Need
Cisco 10720 Internet
Router • To offer high-performance IP services as part of their business strategy
• To simplify current networks and implement simple, scalable, reliable features of DPT
technology while maximizing fiber usage
• Any customer already using DPT technology in their network, most likely with DPT
cards on the 12000 Internet Router

–Per minute broadband access can be pre-paid for via access codes
• Redirects all users through two steps during connection. First, they are directed
to a Connect Screen, which explains the services available to them, including
potentially multiple bandwidth and price options. Once users select and purchase
service, they are directed to a portal page as their first location on the Internet.
This provides a second branding and marketing opportunity
• Pre-authentication of specified domains that includes a “transparent proxy”
feature which allow service providers to force all Web requests to go through the
Microsoft Proxy Server installed on the Cisco BBSM server. When logging is
turned on in the Microsoft Proxy Server application, that allows the software to
capture a list of Web sites visited. This information can be later mined to
determine popular Web sites
• Features to support network installation, configuration, and testing such as
switch discovery; enforced line testing to ensure ports can not be mapped until
the connection meets quality standards, and a limited set of local network
performance monitoring tests to enable proactive quality assurance
Enhancements in Cisco BBSM version 5.1 include:
• RADIUS accounting support, allowing Cisco BBSM to automatically transmit
accounting records to a RADIUS server
• Port hopping, allowing users to transparently hop from wired port to wired port,
providing user mobility within a site
• Supports unlimited walled garden entries, which are entered as an individual IP
addresses or an entire subnet
• Provides installations with limited-bandwidth WAN links a maximum sessions
limit. If a user starts a session that exceeds the configured limit Cisco BBSM
redirects the user to a “system busy” Web page that can be customized
• Cisco Building Broadband Service Director (BBSD) support for multiple BBSM
servers in the field. BBSD allows a service provider or large property

Cisco IOS Software
Overview
The Cisco IOS® Software is a feature-rich network operating system that provides
network intelligence for the majority of today’s Internet and business-critical
networking applications. Supporting Cisco’s extensive range of platforms, Cisco IOS
Software provides a common IP fabric, functionality, and command-line interface
(CLI) across network infrastructures. This common IOS enables a vast array of key
routing functions, multiservice capabilities, traffic shaping, connections,
security/firewall, traffic monitoring, and highly flexible network and product
configuration.
Below is an abbreviated list of key capabilities, intelligent network technologies, and
architectures enabled by Cisco IOS Software:
• Quality of service (QoS)
• Converged data, voice, and video over IP
• IP/ATM/Frame Relay network connectivity and scalability features
• Security/firewall/IPSec/access lists
• Traffic monitoring and NetFlow based monitoring, accounting, billing
• Wide range of routing protocols (including MPLS)
•IPv6
•Multicast
Chapter 10 Cisco IOS Software
10-2
Overview
Quality of Service
Cisco IOS QoS capabilities enable complex networks to control and predictably
service a variety of applications. QoS expedites the handling of mission-critical
applications, while sharing network resources with non-critical applications. QoS
also ensures available bandwidth and minimum delays required by time-sensitive
multimedia and voice applications. It also gives network managers control over
network applications, improves cost-efficiency of WAN connections, and enables
advanced differentiated services.
QoS technologies are elemental building blocks for other Cisco IOS Software
enabling services—particularly for converged data and voice networks (LAN/WAN
+ telephony), video conferencing over IP, IBM networking, as well as for future
business applications in campus, WAN, and service provider networks.
Key QoS Capabilities
Committed Access Rate (CAR) Performs two QoS functions:
• Bandwidth management through rate limiting, which allows you to control
the maximum rate for traffic transmitted or received on an interface
• Packet classification through IP precedence and QoS group setting, which
allows you to partition your network into multiple priority levels or classes
of service (CoS)
Differentiated Services (DiffServ) QoS architecture that divides traffic into a small number of classes and
provides QoS to large aggregates of traffic by treating some traffic better than
the rest (faster handling, more bandwidth on average, lower loss rate on
average). This is a statistical preference, not a hard and fast guarantee
Expedited Forwarding (EF) Per-Hop Behavior (PHB) in the DiffServ standard, used to create a virtual
leased line service
Integrated Services (IntServ) A QoS architecture in which each network element is required to identify the
coordinated set of QoS control capabilities it provides in terms of the
functions it performs, the information it requires, and the information it
exports.
Random Early Detection (RED) Monitors traffic levels on very large networks to prevent congestion and
guarantee priority traffic delivery
Resource Reservation Protocol
(RSVP)
A protocol that supports the reservation of resources across an IP network
Weighted Fair Queuing (WFQ) Adds new levels of control to previous queuing methods
Weighted Random Early
Detection (WRED)
Combines the capabilities of the Random Early Detection (RED) algorithm with
IP Precedence or the DiffServ Code Point (DSCP). This combination provides
for preferential traffic handling for higher-priority packets
10-3

Chapter 10 Cisco IOS Software
CHAPTER 10 CISCO IOS
SOFTWARE
Key QoS Categories
Converged LAN/WAN and Telephony Networks
A broad range of Cisco products support standards-based voice over packet
implementations, including H.323 based VoIP. This enables highly efficient,
converged IP-based telephony in today’s enterprise and service provider networks,
thereby eliminating the need for legacy telephone equipment and overlay networks
(including PBXs, and central office circuit switched network equipment).
Furthermore, a single IT organization can now support campus and enterprise
requirements—regardless if for data, voice, or video requirements.
In addition, Cisco voice-over-packet technologies enable businesses and service
providers to avoid long distance telephone charges by leveraging their existing data
networks, instead of paying for dedicated voice connections and circuits.
Cisco Connectivity and Scalability Solutions
A wide range of access solutions are enabled via the Cisco IOS Software, including:
• Virtual private networking
• Frame Relay, X.25
•ATM
• SONET, OC-x/STM-x, Packet-over-SONET
•DSL
• Broadband services aggregation (including large-scale PPPoE, PPPoA,
L2TP tunneling)
• Dial access (including ISDN, modem, fax, voice)
• VoIP, VoFR, VoATM
• Cable solutions

Security
Cisco’s powerful suite of Cisco IOS Software-embedded security and firewall
technologies includes:
Cisco IOS NetFlow
NetFlow technology provides the metering base for a key set of applications
including network traffic accounting, usage-based network billing, network
planning, network monitoring, outbound marketing, and data mining capabilities
for both service provider and enterprise customers. Cisco provides a set of NetFlow
applications to collect exported NetFlow data, to perform data volume reduction,
and to post-process and display data. Cisco is currently working with a number of
partners to provide customers with comprehensive solutions for NetFlow-based
billing, planning, and monitoring. NetFlow also provides the measurement base for
Cisco’s new Internet Quality of Service (QoS) initiatives. NetFlow captures the traffic
classification or precedence associated with each flow, enabling differentiated
charging based on QoS.
Furthermore, the combination of NetFlow data along with Cisco IOS
Software-based routing information can prove key to developing effective
denial-of-service (DoS) prevention measures and security policies.

IP Routing Protocols
Cisco IOS Software also offers the industry’s widest variety of enterprise and service
provider-class routing protocols including:
• On Demand Routing (ODR)
• Routing Information Protocol (RIP)
• Interior Gateway Routing Protocol (IGRP)
• Open Shortest Path First (OSPF)
• IP Multicast
• Integrated IS-IS
• Enhanced Interior Gateway Routing Protocol (EIGRP)
• Border Gateway Protocol (BGP)
•MPLS
MPLS (Multiprotocol Label Switching)
Cisco IOS MPLS fuses the intelligence of routing with the performance of switching.
It provides significant benefits to networks with pure IP architectures as well as those
with IP and ATM or a mix of other Layer 2 technologies. MPLS technology is key to
implementing scalable virtual private networks (VPNs) and end-to-end QoS,
enabling efficient utilization of existing networks to meet future growth and rapid
fault correction of link and node failure. This technology also helps deliver highly
scalable, differentiated IP services with simpler configuration, management, and
provisioning for both Internet service providers and end-user customers.
Common MPLS Applications Available with Cisco IOS Software
• Traffic engineering is enabled through MPLS mechanisms that allow traffic to be
directed through a specific path, which may not necessarily be the least-expensive
path. Network managers can implement policies to ensure optimal traffic
distribution and improve overall network utilization
• Guaranteed bandwidth is a value-added enhancement to traditional
traffic-engineering mechanisms. MPLS lets service providers deliver guaranteed
pipes and bandwidth allocations. Guaranteed bandwidth also allows
bookkeeping of quality-of-service (QoS) resources to traffic engineer both
premium and best-effort traffic such as voice and data
• Fast reroute (FRR) allows extremely quick recovery if a node or link fails. Such
fast recovery prevents end-user applications from timing out and also prevents
loss of data
Chapter 10 Cisco IOS Software
10-6
Overview
• MPLS VPNs greatly simplify service deployment compared to traditional IP
VPNs. As the number of routes and customers increases, MPLS VPNs easily
scale, while providing the same level of privacy as Layer 2 technologies. In
addition, they can transport non-unique IP addresses across a public domain
• MPLS class-of-service (CoS) capability ensures that important traffic is given the
appropriate priority over the network and that latency requirements are met. IP
QoS mechanisms can be seamlessly implemented in an MPLS environment
MPLS Mechanisms
Cisco IOS MPLS delivers both Traffic Engineering and VPN solutions built on the
following mechanisms:
• Cisco AutoBandwidth Allocator: Automatically increases or decreases MPLS TE
tunnel bandwidth based on measured traffic load
• Constraint-based Routing Label Distribution Protocol (CR-LDP): A signaling
mechanism used to support traffic engineering across a MPLS backbone
• Fast Reroute (FRR): Enables quick recovery in case of link failures, which
prevents end-user applications from timing out and also prevents loss of data
• Label Distribution Protocol (LDP): Provides communication between edge and
core devices. It assigns labels in edge and core devices to establish Label Switched
Paths (LSPs) in conjunction with routing protocols such as OSPF, IS-IS, EIGRP,
or BGP
• Transmission Control Protocol (TCP): Connection-oriented transport-layer
protocol that provides reliable full-duplex data transmission. TCP is part of the
TCP/IP protocol stack

IP Multicast and Multicast Solutions
IP Multicast is a bandwidth-conserving technology that reduces traffic by
simultaneously delivering a single stream of information to thousands of corporate
recipients and homes. Applications that take advantage of multicast technologies
include video conferencing, corporate communications, distance learning, and
distribution of software, stock quotes, and news.
Multicast technology is key to preventing severe network slowdown and Cisco IOS
Multicast is the gateway to Internet broadcasting applications. Internet service
providers (ISPs) and content providers today use Cisco IOS multicast solutions
successfully to host events such as live concerts, radio shows, and football games.
Another exciting application of multicast technologies relates to replacing dedicated
point-to-point telephone/voice circuits and specialized bridging and mixing
multi-user audio conferencing telephone equipment for “always-on” service
(referred to in some industries as “Hoot & Holler” systems). This eliminates the need
for dedicated, costly, overlay voice networks and point-to-point telephone company
circuits, and allows the same capabilities to be implemented over a converged IP
network without requiring users to dial in.
Multicast Solutions
Cisco IOS Multicast solutions are classified as Multicast-Lite, Core Multicast, and
Enhanced Multicast, and are the building blocks for Internet broadcast. Customers
can start with Multicast-Lite, then add more sophisticated interactive
communication capabilities, as needed.
• Multicast-Lite provides for one-to-many broadcast capability with no back
channel. This solution is eminently suitable for content distribution and
broadcasting over the Internet. It does not require setting up of source discovery
across domains and autonomous systems. Multicast Lite includes Protocol
Independent Multicast version 2 (PIMv2), Internet Group Management Protocol
(IGMPv1/v2/v3) and/or Universal Resource Locator Rendezvous
Directory (URD)
• Core Multicast provides interactive, reliable campus multicast for interactive
distance learning, corporate videoconferencing, inventory updates, software
distribution, and content distribution. Core Multicast includes PIM, IGMP, Cisco
Group Management Protocol (CGMP), and now Pragmatic General
Multicast (PGM)
Chapter 10 Cisco IOS Software
10-8
Overview
• Enhanced Multicast provides interactive Internet Multicast across domains for
network gaming, inter company conferencing, Internet software distribution,
and extranet content distribution. Enhanced Multicast includes Multicast Border
Gateway Protocol (MBGP) and Multicast Source Discovery Protocol (MSDP) in
addition to all the protocols supported in Core Multicast
Multicast is currently available across all Cisco IOS Software-based platforms,
including Cisco routers and Cisco Catalyst family switches. Multicast-supported
routing platforms include the following: Cisco 1600, 2500, 2600, 3600, 3800, 7200,
7500, and 12000 series; also available on Catalyst 6000 and 8500 platforms.
Multicast Features
Cisco has the greatest depth of experience with IP Multicast in the industry, and
offers multicast features such as:
Bi-dir PIM An extension to the PIM suite of protocols that implements shared sparse
trees with bi-directional flow of data
Cisco Group Management
Protocol (CGMP)
Ciscodeveloped protocol that allows Layer 2 switches to leverage IGMP
information on Cisco routers to make Layer 2 forwarding decisions
Internet Group Management
Protocol v2 (IGMP)
Used by IP routers and their immediately connected hosts to communicate
multicast group membership states:
• Query: IGMP messages originating from the router(s) to elicit multicast
group membership information from its connected hosts
• Report: IGMP messages originating from the hosts that are joining,
maintaining or leaving their membership in a multicast group
Internet Group Management
Protocol v3 (IGMP)
Version 3 of IGMP adds support for “source filtering,” that is, the ability for a
system to report interest in receiving packets *only* from specific source
addresses, or from *all but* specific source addresses, sent to a particular
multicast address
IGMP Snooping Requires the LAN switch to examine, or “snoop,” some Layer 3 information in
the IGMP packet sent from the host to the router. When the switch hears an
IGMP Report from a host for a particular multicast group, the switch adds the
host’s port number to the associated multicast table entry. When it hears an
IGMP Leave Group message from a host, it removes the host’s port from the
table entry
Inter-domain Multicast Supports inter-domain routing and source discovery across the Internet or
across multiple domains comprising an enterprise
Intra-domain Multicast Supports multicast applications within an enterprise campus
Multicast Source Discovery
Protocol (MSDP)
A mechanism to connect multiple PIM sparse-mode (SM) domains. MSDP
allows multicast sources for a group to be known to all rendezvous point(s)
(RPs) in different domains
Multicast Routing Monitor (MRM) A management diagnostic tool that provides network fault detection and
isolation in a large multicast routing infrastructure
Multi-protocol Extensions
for Border Gateway Protocol
(MBGP)
Also known as BGP+, MBGP adds capabilities to BGP to enable multicast
routing policy throughout the Internet and to connect multicast topologies
within and between BGP autonomous systems
Pragmatic General Multicast
(PGM)
A reliable multicast transport protocol for applications that require ordered,
duplicate-free, multicast data delivery from multiple sources to multiple
receivers. PGM guarantees that a receiver in a multicast group either
receives all data packets from transmissions and retransmissions, or can
detect unrecoverable data packet loss

IPv6
The Internet Protocol version 6 (IPv6), most notably offers expanded IP addresses to
accommodate the proliferation of Internet devices such as personal computers,
personal digital assistants, wireless devices, and new Internet appliances—as well as
the expansion of Internet access—particularly "always-on" connections throughout
the world. IPv6 also provides integrated auto-configuration for plug-and play
capabilities, enhanced mobility and end-to-end security.
Incorporating IPv6 into Cisco IOS Software enables continued growth of the Internet
and its expansion into new applications and capabilities, in a way that maintains
compatibility with existing Internet services.
For more information regarding IPv6, see
www.cisco.com/go/ipv6
Protocol Independent
Multicast (PIM)
A multicast routing architecture that enables IP multicast routing on existing
IP networks:
• SM = Spare Mode (RFC 2362): Relies upon an explicitly joining method
before attempting to send multicast data to receivers of a multicast group
• DM = Dense Mode (Internet Draft Spec): Actively attempts to send
multicast data to all potential receivers (flooding) and relies upon their
self-pruning (removal from group) to achieve desired distribution
Unidirectional Link Routing
Protocol (UDLR)
A routing protocol that provides a way to forward multicast packets over a
physical unidirectional interface (such as a satellite link of high bandwidth) to
stub networks that have a back channel
URL Rendezvous Directory
(URD)
Directly provides the network with information about the specific source of a
content stream. It enables the network to quickly establish the most direct
distribution path from the source to the receiver, thus significantly reducing
the time and effort required in receiving the streaming media. URD allows an
application to identify the source of the content stream through a web page
link or web directly

Overview
Cisco IOS Software General Release Process
There are three categories of Cisco IOS Software releases: Early Deployment, Major,
and General Deployment releases.
• Early Deployment releases (i.e. T, S, X, E release families)—Provide advanced
networking technologies to customers for delivery of leading-edge Internet
applications. They offer new software capabilities, new platforms, and interface
extensions. Customers for whom receiving a new feature is critical to their
competitive advantage will benefit from these releases
• Major releases (i.e. Release 12.2)—Consolidate features, platform support, and
functionality from early deployment releases, and emphasize stability. Regular
maintenance releases do not introduce new functionality or platform support,
but provide continuous improvement and greater quality, leading ultimately to
general deployment
• Releases with General Deployment certification (i.e. Release 12.0)—Have had
extensive market exposure in a wide range of network environments. They are
qualified through extensive metrics that analyze stability, software defect trends,
and customer satisfaction surveys. General deployment releases are used for
major, business-critical applications
At some point, GD releases are replaced by newer releases with the latest networking
technologies. Therefore, a release retirement process has been established with three
principal milestones: End of Sales (EOS), End of Engineering (EOE), and End of Life
(EOL).

Cisco Cable IOS
Chapter 10 Cisco IOS Software
CHAPTER 10 CISCO IOS
SOFTWARE
Cisco Cable IOS
Cisco IOS Software used in Cisco Universal Broadband Router (uBR) products is an
extension of Cisco IOS Software that lays the foundation for:
• Service providers to reliably and effectively deliver differentiated services
• Corporations to safely conduct businesses and daily operations
Cisco IOS Software for cable transparently bridges the differences between HFC and
IP domains. Cable operators can leverage existing HFC infrastructure to offer
value-added IP-based services. Cisco IOS Software for cable offers enhanced stability,
investment protection, reliable performance, and enhanced features. Its features
accent the performance and scalability of the uBR product family. These features
coupled with the proven uBR products elevate Cisco to be the leader in the cable
equipment market.
Cisco uBR products fall under one of the following categories:
• CPE—Cisco cable CPE devices support only the 12.0T Cisco IOS Software
releases and a few Early Deployment (ED) releases
• CMTS—there are a variety Cisco IOS Software trains for Cisco CMTS products.
The Cisco uBR7100 Series and Cisco uBR7200 Series can support 12.1EC,
12.2T, and 12.2BC trains, while the Cisco uBR10012 can only run the 12.2BC
release
Cisco IOS Software for Cisco Cable CPE
The Cisco uBR900 Series Cable Access Router supports a number of feature sets.
Each feature set provides specific functionality, such as firewall or advanced
encryption. All feature sets support base IP bridging as required by DOCSIS. This
allows the Cisco uBR900 Series to transmit data over HFC networks.
The Cisco uBR925 Cable Access Router also supports VoIP. Real-time traffic such as
voice requires different handling than data. Data traffic can be sent on a “best-effort”
basis because it can accept some loss or delay in the transmission of packets. Such
losses and delays are unacceptable for voice calls.
For this reason, the Cisco uBR925 supports DOCSIS QoS enhancements that give
higher priority to IP packets containing voice traffic. This ensures that real-time
traffic is delivered more reliably than “best-effort” data traffic. The telephones and
fax machines connected to the Cisco uBR925 can route their calls over the Internet
using either the H.323v2 (Gateway/Gatekeeper), Simple Gateway Control Protocol
(SGCP), and Media Gateway Control Protocol (MGCP) voice control protocols.
Chapter 10 Cisco IOS Software
10-12
Cisco Cable IOS
Depending on the protocol used and the level of support provided by the service
provider, these calls can be made either to other VoIP devices or to phones connected
to the PSTN.
The following Cisco IOS feature sets support data-only traffic for the Cisco uBR905
and both data and voice traffic for the Cisco uBR925:
• Base IP DOCSIS-Compliant Bridging—Provides full DOCSIS 1.0-compliant
cable modem support for customers who want a basic high-speed connection to
the Internet. This feature set is included in all Cisco IOS images available for the
Cisco uBR900 Series
• Value Telecommuter—Adds IP routing support, DHCP support, NAT and Port
Address Translation (NAT/PAT), 56-bit DES IPSec encryption, and layer 2
tunneling support to DOCSIS-compliant bridging. This allows businesses to
establish secure high-speed Internet connections between employees’ homes and
an office LAN. This is the default software image for the Cisco uBR900 Series
• Performance Telecommuter—Adds advanced 168-bit 3DES IPSec encryption to
functions provided by the Value Telecommuter image. This enables high-speed
and high-security Internet connections between employees’ homes and the
office LAN
• Value Small and Branch Office—Adds the Cisco Secure Integrated Software
(firewall) feature set to functions provided by the Value Telecommuter image.
This allows customers to establish secure connections across the Internet. This
feature set also protects the office network from intrusion and interference and
preserves the permanent high-speed access to the Internet
• Performance Small and Branch Office—Adds advanced 168-bit 3DES IPSec
encryption to the functions provided by the Value Small and Branch Office
image. This allows customers to establish high-security connections across the
Internet. This feature set also protects the office network from intrusion and
interference and preserves the permanent high-speed access to the Internet

CHAPTER 10 CISCO IOS
SOFTWARE
The following table summarizes the features and benefits of Cisco IOS Software
running on the Cisco uBR900 Series.
Feature Benefits
Authentication,
Authorization, and
Accounting (AAA)
Allows centralized servers to provide user authentication, authorization, and
accounting. Compared to router-based authentication, AAA provides for increased
flexibility and control of access configuration, scalability, the possibility of multiple
backup servers, and standardized authentication methods, such as RADIUS
Cable Monitor Web
Diagnostic Tool
Used to display the current status and configuration of the Cisco uBR900 Series. The
Cable Monitor can also be used when the cable network is down, providing an easy
way for subscribers to provide necessary information to service technicians
Cisco Cable Clock
Card Support
The Cisco uBR925 automatically supports the use of the Cisco Cable Clock Card on the
Cisco uBR7246VXR. The Cisco Cable Clock Card enables the Cisco uBR7246VXR to use
a primary and secondary external clock derived from a Stratum 1 source. This provides
a high-quality clocking signal that minimizes jitter and other timing problems that can
interfere with real-time traffic such as VoIP calls
Cisco IOS Firewall The Cisco IOS Firewall feature set provides firewall-specific security features to the
Cisco uBR900 Series. When this feature is enabled, the router acts as a buffer between
the Internet, other public networks, and the private network that is connected to the
router
The firewall-specific security features include the following:
• Authentication proxy services to intelligently apply specific security policies on a
per-user basis
without impacting performance
• Checking packet headers and dropping suspicious packets to detect and prevent
denial of service attacks, such as ICMP and UDP echo packet flooding, SYN packet
flooding, half-open or other unusual TCP connections, and deliberate
mis-fragmentation of IP packets
• Context-Based Access Control (CBAC) which gives internal-to-the-firewall users
secure, per-application-based traffic control across the Internet/Intranet. This includes
protection against Simple Mail Transfer Protocol (SMTP) attacks, one of the most
common attacks against computers connected to the Internet
• Dynamic port mapping to allow network applications with well-known port
assignments to use customized port numbers. This can be done on a host-by-host basis
or for an entire subnet, providing a large degree of control over which users can
access different applications
• Intrusion Detection System (IDS) that recognizes the signatures of the most common
attack profiles. When an intrusion is detected, IDS can perform a number of actions:
send an alarm to a syslog server or to NetRanger Director, drop the packet, or reset the
TCP connection
• Java blocking to protect against destructive Java applets. Applets can be allowed
only from known and trusted sources or blocked completely
• Real time and configurable alerts and audit trail capabilities to record and timestamp
source and destination hosts
• Support for a broad range of commonly used protocols, including H.323 and
NetMeeting, FTP, HTTP, MS Netshow, RPC, SMTP, SQL*Net, and TFTP
• User-configurable audit rules, real-time alerts, and audit-trail logs
DOCSIS-
Compliant Bridging
DOCSIS-compliant bridging allows the Cisco uBR900 Series to operate as a DOCSIS 1.0
cable modem to interoperate with any DOCSIS-qualified CMTS
DOCSIS Baseline
Privacy Interface
The DOCSIS Baseline Privacy Interface (BPI) feature provides data privacy across the
HFC network by encrypting traffic flows between the CM and the CMTS
Available in DOCSIS 1.1, BPI+ provides more secure authentication of cable modems
through the use of digital certificates. Also, a cable modem can use a digital signature
to verify that the software image it has downloaded has not been altered or corrupted
in transit
DHCP Server Include both Intelligent DHCP Relay and DHCP Client functionality
A DHCP Relay Agent is any host that forwards DHCP packets between clients and
servers—this enables the client and server to reside on separate subnets. If the Cisco
IOS DHCP server cannot satisfy a DHCP request from its own database, it can forward
the DHCP request to one or more secondary DHCP servers defined by the network
administrator
Chapter 10 Cisco IOS Software
10-14
Cisco Cable IOS
DHCP Proxy Support The DHCP Proxy Support feature is useful in two situations:
• When the cable access router is configured for routing mode, an IP address must be
assigned to its Ethernet interface. The DHCP Proxy Support feature allows an external
DHCP server to assign an IP address to the Ethernet interface, as opposed to assigning
it manually with the appropriate CLI commands
• When network address translation (NAT) is used, an inside global address pool must
be created on the Ethernet interface. The DHCP Proxy Support feature allows a DHCP
server to assign an IP address that automatically creates the NAT address pool, as
opposed to manually specifying a static IP address with the appropriate CLI commands.
Enhanced Bridging Can connect up to 256 devices in bridging mode
H.323v2
(Gatekeeper/Gateway)
Support VoIP traffic as an H.323v2 gateway. This capability maps an IP address to an
E.164 telephone number, allowing VoIP calls to terminate either on other VoIP devices
or on devices on the PSTN
IPSec Network
Security
This feature provides robust authentication and end-to-end encryption of IP packet.
Both levels of encryption—56-bit and 168-bit—are available, depending on the
software image used
By default, the Cisco uBR900 Series use their onboard hardware accelerator for all
IPsec encryption and decryption. This offers greatly increased performance over
software-based encryption techniques
Media Gateway
Control Protocol
Available on the Cisco uBR925, this feature enables the Cisco uBR925 to function as a
Residential Gateway (RGW), providing an interface between analog FXS phone or fax
systems and the Voice over IP (VoIP) network. The RGW uses a Trunking Gateway
(TGW) to contact the call agent, which in turn provides access to the PSTN
The Cisco uBR925 supports both call waiting and caller ID when using either MGCP or
SGCP for call control. Each of the two voice ports on the router can be configured with
the IP address provided by a single MIB (XGCP-MIB)
Intrusion Detection
System (IDS)
Support for NetRanger IDS that monitors network traffic and detects unauthorized
access to the cable router
NAT and PAT Enable all devices connected to the Internet sharing a single IP address
Quality of Service The Cisco uBR900 Series supports the following QoS features:
• Resource Reservation Protocol (RSVP)—Layer 3 QoS signaling protocol that provides
for the reservation of resources across an IP network
• Distributed Open Signaling Architecture/Session Initialization Protocol
(DOSA/SIP)—Call flow protocol that uses the AT&T VoIP over cable architecture
• DOSA/QoS—Quality of service mechanism used on the AT&T VoIP over cable
architecture
• Committed Access Rate (CAR)—Specifies the minimum bandwidth that is guaranteed
for a particular type of traffic
• Multiservice Identifier (SID)—Allows a service provider to offer different classes of
service to its customers, so that different types of traffic can be given different
priorities of service
• Traffic Shaping—Process of delaying packets that would otherwise be dropped
because they exceed the rate limit on a particular cable modem’s upstream. The router
buffers the upstream packet until bandwidth is available. This is particularly important
with TCP/IP traffic because when a TCP packet is dropped, the destination device
automatically drops all other packets it currently contains in its receive buffer and then
requests the retransmission of those packets. This retransmission of packets increases
the congestion that already exists in this situation, drastically reducing overall
throughput
Routing Information
Protocol –
version 2 (RIP v2)
When configured for routing mode, the Cisco uBR900 Series default to using the
Routing Information Protocol Version 2 (RIPv2). In routing mode, the cable access
router automatically configures itself to use the headend’s IP address as its IP default
gateway. This allows the router to send packets not intended for the Ethernet interface
to the headend
RIPv2 routing is useful for small internetworks because it optimizes Network Interface
Center (NIC)-assigned IP addresses by defining Variable-Length Subnet Masks
(VLSMs) for network addresses, and it allows Classless Interdomain Routing (CIDR)
addressing schema

Cisco IOS Software for Cisco CMTS Products
Cisco CMTS IOS software gives cable operators the ability to deliver differentiated
and revenue-generated services such as VoIP, Internet access, managed VPN services.
A version of Cisco IOS Software running in a Cisco CMTS can be part of Software
Release 12.2 BC, 12.1(EC), or 12.0 SC.
12.0 SC Release Train
Cisco IOS Software Release 12.0 SC is the Cable “stable” release train and is based
on Cisco IOS Software release 12.0 S. This release supports DOCSIS 1.0 only and
has reached End-of-Engineering status. As a result, no new functionality is added to
the 12.0 SC release.
Cisco IOS Software Release 12.0 SC introduced the following software features:
Secured Shell Version 1
(SSH v1)
Allows network administrators to make a secure Telnet connection with the router. SSH
provides for authentication and encryption at the application layer, providing a secure
connection even when BPI or IPSec authentication and encryption are not used at the
network layer. The cable access router can function as both an SSH server and an SSH
client
By default, the SSH feature uses 56-bit DES encryption. Higher security 168-bit 3DES
encryption is available when using Cisco IOS images that support 3DES IPSec
encryption. (The SSH client must also support the same level of encryption.)
Simple Gateway Control
Protocol
SGCP provides for control call setup and teardown for VoIP calls made through the
Internet or a local Intranet. SGCP uses call control agents to communicate with voice
gateways, allowing customers to create a distributed system that enhances
performance, reliability, and scalability while still appearing as a single VoIP gateway to
external clients
Triple Data Encryption

DRP Server Agent
The DRP Server Agent are border routers that support Director Response Protocol
(DRP). This UDP-based protocol enables the Cisco DistributedDirector, a
stand-alone application, to provide dynamic, scalable, and “network intelligent”
Internet traffic load distribution between multiple geographically dispersed servers.
Easy IP (Phase 1)
Easy IP (Phase 1) feature, a combination of NAT and PPP/Internet Protocol Control
Protocol (IPCP), enables a Cisco router to negotiate automatically its own registered
WAN interface IP address from a central server and to enable all remote hosts to
access the Internet using this single registered IP address. This feature is necessary in
order for multiple LAN devices to use the same globally unique IP address so that
these devices can access the Internet using the registered IP address.
Hot Standby 1+1 Redundancy
The Hot Standby 1+1 Redundancy enables a Cisco uBR7100 Series, Cisco uBR7200
Series, or Cisco uBR10012 to wait in hot standby mode to take over service
processing for a primary CMTS in case of system failure. The 1+1 redundancy
feature provides high availability capability essential for VoIP where lack of
redundancy can result in loss of voice calls.
PPPoE Termination
Beginning with Cisco IOS Software Release 12.2(4)BC1, Cisco IOS Software for
cable added support for Point-to-Point Protocol over Ethernet (PPPoE). This feature
allows a direct connection to cable interfaces. The support of PPPoE on cable
interfaces of a Cisco CMTS allows CPE behind a cable modem to use PPP as a
mechanism to obtain their IP address and use this for all subsequent data traffic
similar to a dial-up PPP client. In a PPP dial-up session, the PPPoE session is
authenticated and the IP address is negotiated between the PPPoE client and the
server, which can be either a Cisco CMTS or a Home Gateway.
Per Modem Filter
Per-modem filters give cable operators the ability to filter incoming packets from
individual hosts or cable interfaces based on the source MAC or IP address. This
allows access lists to be specified on a per-interface and per-direction basis. The
packets received from cable interfaces and/or individual hosts are filtered based on
the cable interface or the host the packets are received from.

HSRP over ISL in Virtual LAN Configuration
Inter-Switch Link protocol (ISL) is a Cisco protocol for interconnecting multiple
switches and maintaining VLAN information as traffic goes between switches. ISL
provides VLAN capabilities, while maintaining full wire speed performance on Fast
Ethernet links in full- or half-duplex mode. ISL operates in a point-to-point
environment and will support up to 1000 VLANs. With this feature, cable operators
can define virtually as many logical networks as are necessary for their environment.
For configuration information for Hot Standby Router Protocol (HSRP) over
Inter-Switch Link (ISL) protocol, refer to the chapter titled “Configuring Routing
Between VLANs with Inter-Switch Link Encapsulation,” contained in the Cisco IOS
Switching Services Configuration Guide, Release 12.2 at
www.cisco.com/univercd/cc/td/doc/product/software/ios122/122cgcr/fswtch_c/
IP Network Address Translation / Port Address Translation
NAT is a mechanism for conserving registered IP addresses in large networks and
simplifying IP address management tasks. As its name implies, Cisco IOS NAT
translates IP addresses within private “internal” networks to “legal” IP addresses for
transport over public “external” networks (such as the Internet). Incoming traffic is
translated back for delivery within the inside network. Thus, Cisco IOS NAT allows
an organization with unregistered “private” addresses to connect to the Internet by
translating those addresses into globally registered IP addresses. Cisco IOS NAT also
increases network privacy by hiding internal IP addresses from external networks.
The cable operator can configure several internal addresses with NAT to only one or
a few external addresses by using a PAT feature—also referred to as “overload,” a
subset of NAT functionality.
Management
All CMTS/routers have management capabilities built-in to ease configuration,
management, DOCSIS support, and troubleshooting.

DOCSIS MIB Support
Cisco CMTS products support many Management Information Base (MIB) as
specified in DOCSIS. These MIBs include:
• DOCSIS Ethernet MIB Objects Support (RFC 2665)
• DOCSIS Operational System Support Interface (OSSI), including support for
LinkUpDown Traps (RFC 2233)
• Multicast Source Discovery Protocol MIB (MSDP)
• RF Interface MIB
• SNMP and Cable-specific MIBs such as SNMPv2-SMI.my, IF-MIB,
DOCS-IF-MIB.my, DOCS-BPI-MIB.my
Additionally, Cisco IOS Software for Cable supports SNMP, SNMPv2, and
SNMPv3.
To obtain lists of supported MIBs by platform and Cisco IOS release and to
download MIB modules, refer to the Cisco MIB Web page on Cisco.com at
www.cisco.com/public/sw-center/netmgmt/cmtk/mibs.shtml
Cable Interface Setup Facility
The Cable Interface Setup facility supports a number of functions to ensure cable
interfaces and line cards are fully operational after setup. These include:
• Ability to configure each interface on the system as part of the CMTS
configuration
• Ability to configure the CMTS manually should the user prefer not to use the
autoinstall feature
• Ability to specify a range of interfaces to which subsequent commands are
applied and support the definition of macros that contain an interface range.
The Setup Facility transforms the complicated task of configuring a CMTS, making
it simple.

Enhanced Modem Status Display
Cisco CMTSs support polling of cable modems to obtain parameter and status
information. This capability enables the user to poll and display:
• Downstream receive power levels
• Downstream signal/noise ratios (SNRs)
• Upstream power levels
• Transmit timing offsets
• Micro reflection (in dB)
Internal Modem Configuration File Editor
This feature adds support for internal DOCSIS cable modem configuration file
storage and generation. The cable modem configuration file is generated and stored
as part of the Cisco IOS configuration file. The DOCSIS configuration files are not
stored in Flash memory but are automatically generated when requested for TFTP
downloads to cable modems.
SNMP Cable Modem Remote Query
The remote query feature allows Cisco CMTSs to use SNMP requests to periodically
poll online cable modems to gather signal-to-noise ratio (SNR), upstream power
value, transmit timing offset, micro reflection value, and modem state. After all
statistic parameters are collected, an SNMP trap can be generated to inform the
SNMP manager that the remote query poll is complete.
Interface Bundling
To reduce the number of subnets consumed per Cisco CMTS, cable interface
bundling is used. Multiple cable interfaces can share a single IP subnet. An IP subnet
is required for each bundle. The user can bundle all cable interfaces on a Cisco CMTS
into a single bundle.
Up to four interface bundles can be configured. In each bundle, exactly one interface
must be specified as the master interface, using the “master” keyword. In the case of
a subinterface over a cable bundle, ‘x’ is the interface number of the bundle master.
The subinterface number starts from 1.

Cisco Network Based Application Recognition
This feature is available today only on the Cisco uBR7100 Series and the Cisco
uBR7200 Series. The NBAR feature is a new classification engine that recognizes a
wide variety of network applications that dynamically assign TCP or UDP port
numbers. NBAR enhances existing methods of application-recognition by adding
several new classification features:
• Classification of applications that use statically or dynamically assigned
TCP/UDP port numbers or protocols other than TCP and UDP
• Classification of HTTP traffic by URL, host, or MIME type
• Classification of Citrix ICA traffic by application name
• Classification of application traffic using subport information
NBAR can also classify static port protocols.
After NBAR recognizes an application, the Cisco uBR7100 Series or Cisco uBR7200
Series can invoke specific services appropriate for that application. These services can
provide QoS features such as:
• Guaranteed bandwidth
• Bandwidth limits
• Traffic shaping
•Packet coloring
The Cisco IOS Software NBAR feature can also be used to detect and respond to
denial-of-service and other types of network attacks.
DOCSIS 1.0 QoS
All Cisco CMTSs support QoS as defined by DOCSIS 1.0. Service class profiles can
be configured through the CLI to support the QoS profile number, traffic priority,
maximum upstream bandwidth, guaranteed upstream bandwidth, maximum
downstream bandwidth, maximum transmit burst length, baseline privacy
enable/disable, and type of service (ToS) overwrite byte.
DOCSIS 1.0 QoS Enhancement
A number of DOCSIS QoS enhancements were added to early Cisco IOS Software
releases. These features paralleled some of those that were expected in the DOCSIS
1.1 specification prior to finalization.
10-23
Cisco Cable IOS
Chapter 10 Cisco IOS Software
CHAPTER 10 CISCO IOS
SOFTWARE
• Concatenation Support—DOCSIS Concatenation combines multiple upstream
packets into one packet to reduce packet overhead and overall latency. Using
concatenation, a DOCSIS cable modem makes only one bandwidth request for a
concatenated packet, as opposed to making a different bandwidth request for
each individual packet. This technique is especially effective for burst-intensive
real-time traffic such as voice. Concatenation is enabled by default for current
cable line cards, but can be disabled with the Cisco IOS Software command
• Embedded Client Signaling (dynamic SIDs)—Supports the dynamic creation,
configuration, and deletion of Service Identifiers (SIDs) to accommodate different
classes of service. This allows cable modems to request high-priority or
high-bandwidth data streams as needed, such as when a voice call is made
• IP Precedence-Based Rate Limiting that can be used to ensure traffic, such as
data, does not exceed a preset rate limit and interfere with higher-priority
real-time traffic
• Support for Unsolicited Grants
DOCSIS 1.1 QoS
DOCSIS 1.1 modifies the DOCSIS 1.0 specification to provide better performance,
in particular for voice. DOCSIS 1.1 features are supported in the Cisco IOS 12.2 BC
release train, with additional DOCSIS 1.1 features being supported in certain earlier
Cisco IOS 12.1 EC and 12.0 SC release trains.
DOCSIS 1.1 Service Flow
DOCSIS 1.1 offers enhanced QoS features:
• The DOCSIS 1.0 QoS model (SID) associated with a QoS profile has been
replaced with a service flow model that allows greater flexibility in assigning QoS
parameters to different types of traffic and in responding to changing bandwidth
conditions
• Multiple service flows per CM in either direction due to packet classifiers
• Support for multiple service flows per cable modem allows a single cable modem
to support a combination of data, voice, and video traffic
• Greater granularity in QoS per cable modem in either direction, using
unidirectional service flows
• Dynamic MAC messages that can create, modify, and tear-down QoS service
flows dynamically when requested by a DOCSIS 1.1 cable modem
Chapter 10 Cisco IOS Software
10-24
Cisco Cable IOS
Support for Upstream QoS Models
Supported QoS models for the upstream are:
• Best-effort data traffic
• Committed Information Rate (CIR)—Guaranteed minimum bandwidth
• Unsolicited Grants (UGS)—Constant bit rate (CBR) traffic, such as voice, that is
characterized by fixed size packets at fixed intervals
• Real Time Polling (rtPS)—Real Time service flows, such as video, that produce
unicast, variable size packets at fixed intervals
• Unsolicited Grants with Activity Detection (USG-AD)—Combination of UGS
and RTPS, to accommodate real time traffic that might have periods of inactivity
(such as voice using silence suppression).
• Enhanced time-slot scheduling mechanisms to support guaranteed delay/jitter
sensitive traffic on the shared multiple access upstream link
Concatenation
Concatenation allows a cable modem to send multiple MAC frames in the same time
slot, versus making an individual grant request for each frame. This avoids wasting
upstream bandwidth when sending a number of very small packets, such as TCP
acknowledgement packets.
Dynamic MAC Messages
Dynamic Service MAC messages allow dynamic signaling of QoS between the cable
modem and the CMTS. These messages are DOCSIS link layer equivalents of the
higher layer messages that create, tear down, and modify a service flow. These
messages are collectively known as DSX messages. The DSX state machine module
on the CMTS manages the several concurrent dynamic service transactions between
cable modems and the CMTS. It include state machine support for all three
DOCSIS1.1 DSX MAC messages:
• Dynamic Service Add (DSA)—This message is used to create a new service flow
• Dynamic Service Change (DSC)—This message is used to change the attributes
of an existing service flow
• Dynamic Service Deletion (DSD)—This message is used to delete an existing
service flow

Cisco Cable IOS
Chapter 10 Cisco IOS Software
CHAPTER 10 CISCO IOS
SOFTWARE
Fragmentation (Layer 2)
Layer 2 fragmentation on the upstream prevents large data packets from affecting
real-time traffic, such as voice and video. Large data packets are fragmented and then
transmitted in the timeslots that are available between the timeslots used for the
real-time traffic.
Payload Header Suppression
Payload Header Suppression (PHS) conserves link-layer bandwidth by suppressing
unnecessary packet headers on both upstream and downstream traffic flows.
Dynamic Map-Advance
A CMTS administrator can enhance the upstream throughput from a CM connected
to a Cisco CMTS. The system employs a new algorithm that automatically tunes the
lookahead time in MAPs, based on several input parameters for the corresponding
upstream channel. The use of dynamic and optimal lookahead time in MAPs
significantly improves the per-modem upstream throughput.
Improved Upstream QoS
Supported QoS models for the upstream are:
• Best-effort—Data traffic sent on a non-guaranteed best-effort basis
• Committed information rate (CIR)—Guaranteed minimum bandwidth
for data traffic
• Unsolicited grants (UGS)—Constant bit rate (CBR) traffic, such as voice, that is
characterized by fixed size packets at fixed intervals.
• Unsolicited grants with activity detection (USG-AD)—Combination of UGS and
RTPS, to accommodate real time traffic that might have periods of inactivity
(such as voice using silence suppression). The service flow uses UGS fixed grants
while active, but switches to RTPS polling during periods of inactivity to avoid
wasting unused bandwidth
Chapter 10 Cisco IOS Software
10-26
Cisco Cable IOS
Upstream Address Verification
This feature prevents the spoofing of IP addresses. Using the CLI, administrators can
determine the IP and MAC address of a given cable interface, and the SID number
that shows the IP and MAC addresses learned in the cable interface’s MAC table. The
CMTS verifies the source IP address against the MAC address for the CM. CM and
PC IP addresses are verified to ensure that SID and MAC addresses are consistent.
Using customer databases, administrators can cross-reference a spoofing CM and PC
and prevent further usage.
Cisco uBR-MC16S-based Spectrum Management
Cisco offers a cable line card—the Cisco uBR-MC16S—supported on the Cisco
uBR7200 Series and Cisco uBR10012 that offers advanced spectrum management.
Spectrum management is used to prevent service interruptions due to upstream noise.
Because of the nature of CATV technology, upstream noise management is a
significant issue. Frequency bands must have a sufficient carrier-to-noise ratio (CNR)
and carrier-to-ingress power ratio to support the transmission of quadrature
phase-shift keying (QPSK) and quadrature amplitude modulation (QAM) data.
DOCSIS sets the minimum value for both these ratios to 25 dB in the 5 MHz to 42
MHz frequency range. If CNR drops below 25 dB on a particular channel due to
noise, the cable modem on that channel degrades and can drop off the network.
The Cisco uBR-MC16S line card features advanced spectrum management capability
that records signal-to-noise (SNR) information from 5-to-42 MHz for each upstream
port to determine the noise level and identify clear spectrum should an automatic
frequency hop be required. When the number of missed station management
messages exceed a configured threshold, an upstream channel frequency
reassignment is initiated. The Cisco uBR-MC16S scans the upstream spectrum and
locates a clean, available upstream channel within the defined spectrum group.
Dynamic Upstream Modulation
The Cisco uBR-MC16S supports dynamic upstream modulation. This feature
reduces the risks associated with transitioning to QAM 16 in the return path, and
provides assurance that subscribers remain online and connected during periods of
return-path impairments.

Intelligent Spectrum Management Enhancements
Intelligent spectrum management enhancements to the Cisco uBR-MC16S line card
were introduced in the Cisco IOS Release 12.1 EC train. Initial support for the Cisco
uBR-MC16S card also appeared in Cisco IOS Releases 12.0(7)XR3, 12.1(1a)T1, and
12.1(2)EC. Additions:
• Integrates a DOCSIS cable interface line card with an onboard spectrum analyzer
that continuously analyzes upstream spectrum quality in the DOCSIS frequency
range of 5 to 42 MHz
• Includes hardware-assisted frequency hopping, providing for more intelligent
and faster frequency selection than software-only solutions
• Reduces the response time to ingress noise that can cause modems to drop offline.
• Eliminates blind frequency hopping by initiating frequency hops to known
clean channels
• Improves frequency agility to help eliminate dropped packets and thereby
maintain full upstream data rates
• Supports frequency agility in dense-mode combining environments across a
shared spectrum
• Restricts frequency hopping to a set of discrete frequencies or to a range of
frequencies, as desired
• Allows frequency hopping conditions to be customized for specific plant
environments and requirements
• Optionally schedules frequency hops to take advantage of known usage patterns
or plant conditions
• Optionally dynamically reduces channel width to allow cable modems to remain
online, even in noisy upstream conditions
Advanced Spectrum Management Features
Advanced spectrum management features for the Cisco uBR-MC16S cable interface
line card appeared in Cisco IOS Release 12.1(7)CX as a software-only upgrade.
These enhancements:
• Support proactive channel management to avoid the impacts of ingress and keep
subscribers online and connected
• Offer flexible configuration choices, allowing users to determine the priority of
the actions to be taken when ingress noise on the upstream exceeds allowable
thresholds. The configurable actions are frequency hopping, switching the
modulation profile, and reducing the channel width
Chapter 10 Cisco IOS Software
10-28
Cisco Cable IOS
• Perform carrier-noise ratio (CNR) calculations using Digital Signal Processor
(DSP) algorithms in real-time on a per-interface and a per-modem basis
• Intelligently determine when to modify the frequency, channel width, or
modulation profile, based on CNR calculations in the active channel, number of
missed station maintenance polls, correctable FEC errors, or uncorrectable FEC
errors
• Enhance the Dynamic Upstream Modulation feature for the Cisco uBR-MC16S
line card. This feature supports dynamic modulation using two upstream
profiles. The primary profile remains in effect at low noise conditions. If
upstream conditions worsen, cable modems switch to the secondary profile to
avoid going offline. When noise conditions improve, modems are moved back to
the primary profile
• Provide an SNMP interface so that a network management workstation or other
graphical tool can obtain spectrum information for a particular cable modem or
for an entire upstream. The frequency resolution can be as fine as 12 KHz
• Support the DOCSIS Cable Modem Test Analyzer (DCMTA) tool from Acterna.
The DCMTA software provides spectrum analyzer capability for an individual
upstream port or an individual cable modem
Downstream Traffic Shaping
Downstream traffic shaping (to include Type-of-Service) allows traffic shaping from
the CMTS on a DOCSIS downstream channel. Downstream traffic shaping limits
surges on output interfaces to reduce downstream congestion.
Downstream rate limiting with ToS enables you to partition downstream traffic for
a CM into multiple classes of service and multiple data rates by using the three
precedence bits in the ToS byte in the IP header to specify a class of service
assignment for each packet. Those packets with the precedence bit set in the ToS field
are given higher priority.
Upstream Traffic Shaping
Upstream traffic shaping allows the CMTS to perform rate limiting on a DOCSIS
upstream channel. Upstream traffic shaping enables the CMTS to enforce the peak
upstream rate for each CM without degrading overall TCP performance for the
subscriber CMs.

• Context-Based Access Control (CBAC) that intelligently filters TCP and UDP
packets based on the application-layer protocol
• Detection and prevention of the most common denial of service (DoS) attacks,
such as ICMP and UDP echo packet flooding, synchronize/start (SYN) packet
flooding, half-open or other unusual TCP connections, and deliberate
misfragmentation of IP packets
• Support for a broad range of commonly used protocols, including H.323 and
NetMeeting, FTP, HTTP, MS Netshow, RPC, SMTP, SQL*Net, and TFTP
• Authentication Proxy for authentication and authorization of web clients on a
per-user basis
• Dynamic port mapping that maps the default port numbers for well-known
applications to other port numbers. This can be done on a host-by-host basis or
for an entire subnet, providing a large degree of control over which users can
access different applications
• Configurable alerts and audit trail
• Intrusion Detection System (IDS) that recognizes the signatures of 59 common
attack profiles
• User-configurable audit rules; configurable real-time alerts and audit trail logs
MPLS VPN Support for Subinterfaces
The Cisco CMTS offer MPLS VPN support for subinterfaces and cable interface
bundles. Using MPLS VPN technology, service providers can create scalable and
efficient private networks using a shared hybrid fiber coaxial (HFC) network and
Internet protocol (IP) infrastructure.

Cable IP Network Architecture Description
This section overviews basic cable architectures associated with each of the main
service types—data, voice, and video—and discusses Cisco products used in the
deployment of these services. Cisco solutions make it possible for cable service
providers to augment existing HFC infrastructures and introduce two-way cable IP
data, voice, and video services. Since all services employ an IP-based backbone, much
of the initial investment required can be leveraged among multiple services.
Basic Broadband Access Architecture
To evolve an existing HFC network for two-way services, the architecture for the
cable network needs to have the following components:
• The high-speed network backbone transports data, voice, and video to external
networks which support these applications
• The headends pass data, voice, and video between the backbone and hub/HFC
network. Centralized equipment such as provisioning servers, OSS servers, and
billing support system servers typically reside at the headend. If the cable service
provider offers voice services, call gateways and call agent software are required
at the headend

Cable IP Network Architecture Description
• The hubs/HFC network connect the subscriber premises to the
headend/backbone infrastructure. They convert the traditional digital packets
(seen in the headends and on the backbone) into the RF format used to transmit
the information through the fiber coaxial portions of the plant
• DOCSIS or EuroDOCSIS-compliant CPE reside at the customer premises and
convert the RF data streams generated at the hub and carried over the HFC
network into the usable data, voice, and video information supplied to the
end-user. Examples of CPE include cable modems (CMs), set-top boxes (STBs),
multimedia terminal adapters (MTAs), and VoIP telephones
High-Speed Network Backbone
A high-speed digital backbone network connects the network of a large cable
operator to the rest of the world (in very large cable service provider networks,
backbones also are used to carry data between different regions of the cable IP
infrastructure). The backbone connects to other networks such as the PSTN, other
cable system backbones, and Internet connection points. See Overview, page viii, for
illustration of a large multiservice network.
Headend
The principle role of the headend is to bring external services—satellite video,
off-the-air video, Internet data, and voice—into the cable operator’s access network.
In some instances, several headends will be used in each region, each with somewhat
different roles in voice, video content, and Internet connectivity. Typically, headends
contain a gigabit switch router such as the Cisco 12000 Series Internet Router to pass
12-3
Cable IP Network Architecture Description
Chapter 12 Reference Information
CHAPTER 12 REFERENCE
INFORMATION
traffic between external sources and the internal network. Multiservice networks
might also contain the Cisco ONS 15454 or Cisco ONS 15327, part of the Cisco
Complete Optical Multiservice Edge and Transport (COMET) product portfolio.
These products bring the capacity of the metropolitan market up to par with the core
and overcome what has been referred to as a “services bandwidth barrier” that
strands capacity in the core from reaching the end customer. Cisco Catalyst®
switches can be used to route local traffic between the gigabit switch router and the
servers—OSS, billing system servers, and so on—located at the headend. If a cable
service provider chooses to offer voice services, a key component of the headend is
the telephony gateway. This component gives the broadband network the ability to
interoperate with the PSTN. Other elements in the headend include: IP/MPEG
remuxes, MPEG compressors, analog receivers, satellite receivers/scramblers, and
descramblers.
Hub/HFC Network
Hubs contain equipment that converts between the backbone format and the format
required for a particular data, voice, or video access network. Internal components
of the hub include modulators, receivers, scramblers/descramblers, remuxes, codecs,
and cache servers. Hubs may additionally receive off-the-air video streams in analog
format or digital video from satellite feeds.
At the center of the Cisco two-way hub architecture is the Cisco CMTS/router—
the Cisco uBR7100 Series in small operations, Cisco uBR7200 Series in small-, mid-
to large-sized operations, or the Cisco uBR10012 in large operations. The Cisco
CMTS/router connects subscribers on the HFC plant to the backbone network
through both local area network (LAN) and wide area network (WAN) interfaces. If
traffic demands are high, more than one CMTS/router may be required based on the
CMTS platform chosen. In some instances, a Cisco 10000 Series may be used to
aggregate traffic before it is passed to the headend.
Multiservice networks must accommodate a mix of network support features based
on packet type. Data is bursty, requiring error-free, high-bandwidth service on an
occasional basis. Voice is time-sensitive, requiring a small amount of bandwidth
all the time, and precise metering to assure quality reception. Video is both
bandwidth-hungry and time-sensitive, requiring high bandwidth at a steady rate.
Unlike data, both voice and video can accommodate low error rates with little impact
on perceived quality.
