Cisco IOS Release 12.3(13a)BC introduces the ability to exclude trusted MAC addresses from standard DHCP source verification checks, as supported in previous Cisco IOS releases for the Cisco CMTS. This feature enables packets from trusted MAC addresses to pass when otherwise packets would be rejected with standard DHCP source verification.
Page 37: Cisco.com
The service ID (SID) and the source IP address of the packet must match those in the ARP host database on the Cisco CMTS. If the packet check succeeds, the packet is allowed to pass. Rejected packets are discarded in either of these two checks.

Page 39: Docsis 1.0 Feature Support
DOCSIS 1.0-based, they receive regular DOCSIS 1.0 treatment from the CMTS. DOCSIS 1.0 Baseline Privacy Interface The Cisco uBR10012 router supports full DOCSIS 1.0 Baseline Privacy Interface (BPI) specifications. The BPI for DOCSIS 1.0 protects user data privacy across the shared-medium cable network and prevents unauthorized access to DOCSIS-based data transport services across the cable network.
Page 40 Cisco IOS release 12.3(13a)BC introduces support for the DOCSIS 1.0 concatenation override feature on the Cisco uBR10012 router. This feature provides the ability to disable concatenation on DOCSIS 1.0 cable modems, even in circumstances where concatenation is otherwise supported for the upstream channel.
Page 41 Cisco uBR10012 router schedules fixed periodic slots on the upstream for that traffic flow. The CM does not have to contend for these slots and, because the Cisco uBR10012 router controls the timing of slots, it has precise control over potential delay and jitter.

Page 43 Supported Software Features for the Cisco uBR10012 Router DOCSIS 1.0 Multi SID Support This feature allows the Cisco uBR10012 router to support the definition of multiple SIDs on the upstream. This includes multiple service classes per cable interface, enabling administrators to delegate higher priority as required.
Page 44: Tos Overwrite
CMs subscribing to a class with no minimum upstream rate on the upstream channel. The Cisco uBR10012 router also supports multiple service classes per CM and dynamic service identifiers. This allows the Cisco uBR10012 router to dynamically allocate and delete service flows.
Page 45 Cisco IOS release 12.3(13a)BC introduces Enhanced Rate Bandwidth Allocation (ERBA) support for DOCSIS 1.0 cable modems and the Cisco uBR10012 router. ERBA allows DOCSIS1.0 modems to burst their temporary transmission rate up to the full line rate for short durations of time. This capability provides higher bandwidth for instantaneous bandwidth requests, such as those in Internet downloads, without having to make changes to existing service levels in the QoS Profile.
Page 46 Chapter 1 Overview of Cisco uBR10012 Universal Broadband Router Software Supported Software Features for the Cisco uBR10012 Router ERBA for DOCSIS 1.0 cable modems is supported with these new or enhanced commands or keywords in Cisco IOS release 12.3(13a)BC: •...
Page 47 The QoS profile’s downstream burst size in bytes. To display ERBA settings as applied to DOCSIS 1.0 cable modems and QoS profiles on the Cisco CMTS, use the show cable qos profile command in Privileged EXEC mode. The following example of the cable qos profile command in global configuration mode illustrates changes to the cable qos profile command.
Page 48 Supported Software Features for the Cisco uBR10012 Router Usage Guidelines If a cable modem registers with a QoS profile that matches one of the existing QoS profiles on the Cisco CMTS, then the maximum downstream burst size, as defined for that profile, is used instead of the default DOCSIS QoS profile of 1522.
Page 49: Docsis 1.0+ Feature Support
DOCSIS 1.0+ Feature Support In response to the limitations of DOCSIS 1.0 in handling real-time traffic, such as voice calls, Cisco created the DOCSIS 1.0+ extensions to provide the more important QoS enhancements that were expected in DOCSIS 1.1. In particular, the DOCSIS 1.0+ enhancements provide basic Voice-over IP (VoIP) service over the DOCSIS link.

These QoS attributes define a particular class of service and determine characteristics such as the maximum bandwidth for the service flow and the priority of its traffic.
Page 58 Supported Software Features for the Cisco uBR10012 Router DOCSIS 1.1 Rate Limiting and Traffic Shaping Cisco IOS Release 12.2XF software supports rate limiting per DOCSIS-1.0-99, which limits the data rate to and from a CM; the MAC scheduler supports traffic-shaping capabilities for downstream and upstream traffic.
Page 59 CMs are assigned to operate on specific cable channels to balance activity across several channels. Each Cisco uBR10012 router cable interface card serves a specific downstream channel and upstream segment. Part of network planning is to define the channels to use.
Page 60 Chapter 1 Overview of Cisco uBR10012 Universal Broadband Router Software Supported Software Features for the Cisco uBR10012 Router The CMTS administrator defines and pushes DHCP and DOCSIS configuration files to appropriate servers so that each CM or CM in an STB on the network, when initialized, can transmit a DHCP request, receive its IP address, obtain its TFTP and ToD server addresses, and download its DOCSIS configuration file (and updated software image, if needed).

Page 158: Setting The Upstream Channel Width
HFC network, you might experience packet loss or loss of cable interface connectivity. For QAM-16 channel widths of 400 kHz (320 ksps) or greater, Cisco recommends that you use Note QAM-16 modulation for long and short data, and that you use QPSK for request, initial, and station communications.
Page 159: Setting The Upstream Frequency
Setting the Upstream Frequency The upstream channel frequency of your RF output must be set to comply with the expected input frequency of your Cisco cable interface line card. To configure upstream channel frequencies, perform one of the following tasks: Configure a fixed frequency from 5 to 42 MHz for NTSC operations, then enable the upstream port.
Page 160 (in MHz), the more difficulty you might have. Enter a center frequency between 20 and 38 MHz if you have difficulty. You can also select a default that does not set a specific fixed value. The Cisco uBR10000 series Note software instructs the cable interfaces to use this frequency as the center frequency.
Page 161: Setting The Upstream Input Power Level
Setting the Upstream Input Power Level The Cisco uBR10012 router controls the output power levels of CMs to meet the desired upstream input power level. The nominal input power level for the upstream RF carrier is specified in decibels per millivolt (dBmV).

To activate IP multicast echo, use the following command in cable interface configuration mode: Command Purpose Enables IP multicast echo.
Page 169 This allows the cable network to behave like a standard Ethernet network in terms of its handling of multicast IP traffic. However, on the Cisco uBR10012 router, input access lists are not applied to the multicast traffic that is echoed on each downstream. To control the echoed multicast traffic, you therefore need to configure an output access list and apply it to each downstream interface.

NTSC is compatible with the Consultive Committee for International Radio (CCIR) Standard M. PAL, used in West Germany, England, Holland, Australia, and several other countries. Cisco 6-MHz products can be used in Cisco 8-MHz cable plants. The products, however, operate at Note a maximum downstream bandwidth of 27 Mbps, ignoring 2 MHz of available channel width, and limiting upstream channel choices to the range below 42 MHz.
Page 218: Overview Of Docsis Ntsc Cable Plants
CMTS MAC domains per cable interface line card. Cisco provides high-speed routers to route interactive traffic between the backbone and Ethernet in the headend internal network. Signaling protocols maintain the network intelligence needed to route traffic optimally, automatically building and maintaining routing tables to direct traffic and signal failures for rerouting in the network.

Cisco IOS Release 12.2XF software supports extensions to DOCSIS 1.0 to operate with DOCSIS 1.0-based CMs or cable RF CPE devices (such as Cisco uBR924 cable access routers or Cisco uBR910 cable data service units) that also support DOCSIS 1.0 extensions.
Page 220: Overview Of Docsis-Compliant Upstream Signals
The stream of initial ranging slots and bandwidth request minislots comprise two separate contention subchannels on the upstream. Cisco IOS Release 12.2XF software uses a “dynamic bandwidth-request minislots-per-MAP” algorithm to dynamically control the rate of contention slots for initial ranging and bandwidth requests.
Page 221: Overview Of Docsis Two-Way Server Requirements
QAM uses both phase and amplitude to carry information. If your cable plant is susceptible to ingress or noise, Cisco recommends QPSK, based on the importance of the data. Frequencies below 20 MHz are more susceptible to noise and might require lower symbol rates.
Page 222 Note newer plants. These plants produce more noise and signal level variances. Cisco recommends you keep input to all amplifiers at the same power level in the upstream Tips direction and keep output of all amplifiers in the downstream direction at the same power level.
Page 223 Ideally, the network is sized so that it supports all subscribers being active at the same time at the maximum data rate. This results in an expensive network, however, where full capacity, particularly for residential subscribers, is rarely used. Cisco recommends designing your network to support a given level of over-subscription.
