System Requirements
This section describes the system requirements for Cisco Release 12.2(15)CX1 and includes the following sections:
•Determining Your Software Release
•Upgrading to a New Software Release
Memory Recommendations
Cisco IOS Release 12.2(15)CX1 provides two different boot images for the Cisco uBR7200 series routers:
•ubr7200-kboot-mz.122-15.CX.bin
The "kboot" version of the boot image is a new version of the boot image software that can run only on the Cisco uBR7200-NPE-G1 processor and the UBR7200-I/O-2FE/E I/O controller, because it is too large to load on the other I/O controllers. This image contains support for almost all supported port adapters, allowing the Cisco uBR7246VXR router to boot over almost any type of WAN interface.
•ubr7200-boot-mz.122-15.CX.bin
The "boot" version of the boot image is small enough to be loaded on I/O controllers with 4MB of Flash memory, but it supports only Ethernet, FastEthernet, Gigabit Ethernet, OC POS, and a limited number of ATM port adapters. If you are using a serial port adapter or most ATM port adapters, you will not be able to boot over the WAN interface.
This difference in boot images affects only the ability of the Cisco uBR7246VXR router to boot over the WAN interface. When the router has successfully loaded the Cisco IOS software, it will have connectivity over all of the port adapters that this particular version of Cisco IOS software supports.
Table 4 displays the memory recommendations of the Cisco IOS feature sets for the Cisco uBR7200 series universal broadband routers for Cisco IOS Release 12.2(15)CX1. Cisco uBR7200 series routers are only available with a 48 MB or 128 MB of Flash disk memory on the I/O Controller cards. The UBR7200-NPE-G1 uses compact Flash disk only.
Note Flash disks, an alternative to linear Flash memory, are Flash memory-based devices that can be used as file storage media in the PCMCIA card slots of the I/O Controllers. Each I/O Controller has two PCMCIA slots and can be configured with up to 256 MB of Flash disk memory.
The image subset legend for Table 4 is as follows:
•i = IP routing, MPLS-VPN support, and noncable interface bridging, including Network Address Translation (NAT)
•k8 = DOCSIS Baseline Privacy
•p = IP routing with Intermediate System-to-Intermediate System (IS-IS) and Border Gateway Protocol (BGP); MPLS-VPN support; no bridging and no NAT
•s = "Plus" features: NAT and Inter-Switch Link (ISL)
•k9 = 3DES level of encryption
Note All images support all of the hardware listed in the "Supported Hardware" section, unless otherwise indicated.
System Interoperability
This section clarifies the operation of certain features in the Cisco uBR7200 series universal broadband routers.
•DOCSIS 1.0 Baseline Privacy
DOCSIS baseline privacy interface (BPI) gives subscribers data privacy across the RF network, encrypting traffic flows between the CMTS and CM. BPI ensures that a CM, uniquely identified by its Media Access Control (MAC) address, can obtain keying material for services only it is authorized to access.
To enable BPI, choose software at both the CMTS and CM that support the mode of operation. For the Cisco uBR7200 series software, choose an image with "k8" in its file name or BPI in the feature set description.
The CM must also support BPI. CMs must have factory-installed RSA private/public key pairs to support internal algorithms to generate key pairs prior to first BPI establishment. BPI must be enabled using the DOCSIS configuration file.
Note RSA stands for Rivest, Shamir, and Adelman, inventors of a public-key cryptographic system.
•CM Interoperability
–The Cisco uBR7200 series interoperates with DOCSIS-based two-way CMs that support basic Internet access, VoIP, or Virtual Private Networks (VPNs).
–EuroDOCSIS CMs or STBs with integrated EuroDOCSIS CMs using Cisco uBR-MC16E cable interface line cards and Cisco IOS Release 12.2(4)BC1 or higher. EuroDOCSIS operation support includes 8-MHz Phase Alternating Line (PAL) or Systeme Electronique Couleur Avec Memoire (SECAM) channel plans.
Note Cisco IOS Release 12.2(15)CX1 does not support telco-return CMs/STBs.
•DOCSIS 1.0 Extensions
The Cisco uBR7200 series supports the following DOCSIS 1.0 quality of service (QoS) extensions:
–Multi-Service ID (SID) support, allowing the definition of multiple SIDs on the upstream—Voice traffic can be designated on a higher QoS committed information rate (CIR) secondary SID, while data traffic can be forwarded on a best-effort basis on a primary SID. Secondary SIDs are higher QoS CIR-type classes that have a nonzero minimum reserved rate (CIR-type service). These SIDs receive preferential treatment at the CMTS for grants over any tiered best-effort type data SID of that upstream. Reliable operation with voice requires multiple SIDs—at least two per CM to separate voice from data. In DOCSIS 1.0, SIDs are set up statically. When supporting DOCSIS 1.0 extensions, SIDs can be set up statically or dynamically. Both the CMTS and CM must support this capability.
–CM-initiated dynamic MAC messages—Dynamic Service Addition (DSA) and Dynamic Service Deletion (DSD). These messages allow dynamic SIDs to be created and deleted at run-time on a per-VoIP call basis.
–Unsolicited grant service (constant bit rate [CBR] scheduling) on the upstream—This helps provide a higher-quality channel for upstream VoIP packets from an Integrated Telephony Cable Modem (ITCM) such as the Cisco uBR924 cable access router.
–Ability to provide separate downstream rates for any given ITCM, based on the IP-precedence value in the packet—This helps separate voice signaling and data traffic that goes to the same ITCM to address rate-shaping purposes.
–Concatenation—To increase the per-CM upstream throughput in certain releases of software, Cisco uBR7200 series software supports a concatenated burst of multiple MAC frames from a CM that supports concatenation.
Note All DOCSIS 1.0 extensions are activated only when a CM or Cisco uBR924 that supports these extensions solicits services using dynamic MAC messages or the feature set. If the CMs in your network are pure DOCSIS 1.0-based, they receive regular DOCSIS 1.0 treatment from the CMTS.
•Clock Synchronization
The Cisco uBR7200 series support clock hardware and software to enable high-quality delivery of IP telephony services through synchronized data transmissions. To support the clock feature set, a Cisco uBR7246VXR chassis must be used. The Cisco uBR7246VXR must contain a clock card and either a Cisco uBR-MC16E or Cisco uBR-MC28C cable interface line card. Only these cards support the external clock reference from the clock card to distribute that signal to CMs or STBs attached to the specific network segments.
Each cable modem must also support VoIP applications and the clock reference feature set to enable synchronized timing. The Cisco uBR924 and Cisco uBR925 cable access routers, running Cisco IOS Release 12.0(7)T or later, supports the clock reference feature set automatically.
•National Clock Card
The Cisco uBR7246VXR supports the National Clock Card. The National Clock Card allows the Cisco uBR7246VXR to accept a primary or secondary external clock reference. If there is no primary clock, the Clock Card goes into Holdover. After a period of 2-10 seconds, the Clock Card switches to the secondary clock. When the primary clock is back online, the Clock Card switches to the primary clock after a period of 2-10 seconds. The National Clock Card requires the Cisco uBR-MC1xS or the Cisco uBR-MC1xE cable interface line card.

Note Cisco IOS Release 12.2(15)CX1 is based on Cisco IOS Release 12.2(15)BC1. All features in Cisco IOS Release 12.2(15)BC1 are in Cisco IOS Release 12.2(15)CX1. To view the features in Cisco IOS Release 12.2(15)BC1, see the Release Notes for Cisco uBR7200 Series for Cisco IOS Release 12.2 BC at the following URL and click on New and Changed Information:
http://www.cisco.com/univercd/cc/td/doc/product/software/ios122/122relnt/ubr7200/u7208bc1.htm
New Hardware Features in Release 12.2(15)CX1
Cisco uBR-MC16U/X
The Cisco uBR-MC16U and Cisco uBR-MC16X (Cisco uBR-MC16U/X) cable interface line cards are two of the new Broadband Processing Engine (BPE) series of cable interfaces that are available for the Cisco uBR7246VXR universal broadband router. The BPE cards provide increased performance and advanced Radio Frequency (RF) management, as well as innovative, integrated tools for sophisticated content, traffic and network management.
The Cisco uBR-MC16U/X card has one downstream port and six upstream ports, organized into a single DOCSIS MAC domain. There are two versions, the Cisco uBR-MC16U and the Cisco uBR-MC16X, which are identical except for the type of upconverter that the downstream ports use:
•Cisco UBR-MC16U card—Each downstream port includes an onboard integrated upconverter that generates an RF signal suitable for connection to a combiner and transmission on the coaxial cable network, without the need for any external upconverters.
•Cisco uBR-MC16X card—The downstreams on this card do not include integrated upconverters. Instead, the downstream ports generate an IF signal that must be converted through an external upconverter before transmission on the cable network. This allows the Cisco uBR-MC16X card to easily replace existing line card installations that currently use external upconverters.
Note The downstream on the Cisco uBR-MC16U card is labelled xc RF" to indicate that it outputs an RF-wave from the internal upconverter. The downstream on the Cisco uBR-MC16X card is labelled "DS" to indicate that it outputs an IF-wave that requires an external upconverter.
In Cisco IOS Release 12.2(15)CX and later releases, the downstream ports support 64-QAM and 256-QAM, and the upstream ports support QPSK, 8-QAM, 16-QAM, 32-QAM, and 64-QAM modulation, depending on the upstream's mode of operation.
Depending on the configuration, the Cisco uBR-MC16U/X line card supports either DOCSIS or Euro-DOCSIS operation:
•DOCSIS cable networks are based on the ITU J.83 Annex B physical layer standard and Data-over-Cable Service Interface Specifications (DOCSIS, Annex B) specification, which use 6 MHz National Television Systems Committee (NTSC) channel plans. In this mode, the downstream uses a 6 MHz channel width in the 85 to 860 MHz frequency range, and the upstream supports multiple channel widths in the 5 to 42 MHz frequency range.
•EuroDOCSIS cable networks are based on the ITU J.112 Annex A physical layer standard and European DOCSIS (EuroDOCSIS, Annex A) specification, which use 8 MHz Phase Alternating Line (PAL) and Systeme Electronique Couleur Avec Memoire (SECAM) channel plans. In this mode, the downstream uses an 8 MHz channel width in the 85 to 860 MHz frequency range, and the upstream supports multiple channel widths in the 5 to 65 MHz frequency range.
When operating in either the DOCSIS or EuroDOCSIS mode of operation, the Cisco uBR-MC16U/X card supports the following types of networks:
•TDMA-only mode, which supports only DOCSIS 1.0 and DOCSIS 1.1 cable modems.
•A-TDMA-only mode, which supports DOCSIS 2.0 cable modems.
•Mixed TDMA/A-TDMA mode, which supports both DOCSIS 1.0/DOCSIS 1.1 and DOCSIS 2.0 cable modems on the same upstream.
For more information, see Configuring the Cisco uBR-MC16U/X Cable Interface Line Card at the following URL:
Note The Cisco uBR-MC16U/X card also supports the extended frequency ranges that are used in Japanese Annex B networks: 70 to 860 MHz (downstream) and 5 to 55 Mhz (upstream).
Cisco uBR-MC28U/X
The Cisco uBR-MC28U and Cisco uBR-MC28X (Cisco uBR-MC28U/X) cable interface line cards are two of the new Broadband Processing Engine (BPE) series of cable interfaces that are available for the Cisco uBR7246VXR universal broadband router. The BPE cards provide increased performance and advanced Radio Frequency (RF) management, as well as innovative, integrated tools for sophisticated content, traffic and network management.
Note The downstream on the Cisco uBR-MC28U card is labelled "DS0 RF" to indicate that it outputs an RF-wave from the internal upconverter. The downstream on the Cisco uBR-MC28X card is labelled "DS" to indicate that it outputs an IF-wave that requires an external upconverter.
In Cisco IOS Release 12.2(15)CX and later releases, the downstream ports support 64-QAM and 256-QAM, and the upstream ports support QPSK, 8-QAM, 16-QAM, 32-QAM, and 64-QAM modulation, depending on the upstream's mode of operation.
Depending on the configuration, the Cisco uBR-MC28U/X line card supports either DOCSIS or Euro-DOCSIS operation:
•DOCSIS cable networks are based on the ITU J.83 Annex B physical layer standard and Data-over-Cable Service Interface Specifications (DOCSIS, Annex B) specification, which use 6 MHz National Television Systems Committee (NTSC) channel plans. In this mode, the downstream uses a 6 MHz channel width in the 85 to 860 MHz frequency range, and the upstream supports multiple channel widths in the 5 to 42 MHz frequency range.
•EuroDOCSIS cable networks are based on the ITU J.112 Annex A physical layer standard and European DOCSIS (EuroDOCSIS, Annex A) specification, which use 8 MHz Phase Alternating Line (PAL) and Systeme Electronique Couleur Avec Memoire (SECAM) channel plans. In this mode, the downstream uses an 8 MHz channel width in the 85 to 860 MHz frequency range, and the upstream supports multiple channel widths in the 5 to 65 MHz frequency range.
When operating in either the DOCSIS or EuroDOCSIS mode of operation, the Cisco uBR-MC28U/X card supports the following types of networks:
•TDMA-only mode, which supports only DOCSIS 1.0 and DOCSIS 1.1 cable modems.
•A-TDMA-only mode, which supports DOCSIS 2.0 cable modems.
•Mixed TDMA/A-TDMA mode, which supports both DOCSIS 1.0/DOCSIS 1.1 and DOCSIS 2.0 cable modems on the same upstream.
Note The Cisco uBR-MC28U/X card also supports the extended frequency ranges that are used in Japanese Annex B networks: 70 to 860 MHz (downstream) and 5 to 55 Mhz (upstream).

New Hardware Features in Release 12.2(15)CX
Cisco uBR-MC16U/X and Cisco uBR-MC28U/X Cable Interface Line Cards
Cisco IOS Release 12.2(15)CX introduces support for the following new cable interface line cards,
•The Cisco uBR-MC16U/X card provides one downstream port and six upstream ports. In Cisco IOS Release 12.2(15)CX, the downstream ports support 64-QAM and 256-QAM, and the upstream ports support QPSK, 8-QAM, 16-QAM, 32-QAM, and 64-QAM modulation, depending on the upstream's mode of operation.
•The Cisco uBR-MC28U/X card provides two downstream ports and eight upstream ports, organized into two DOCSIS MAC domains. In Cisco IOS Release 12.2(15)CX, the downstream ports support 64-QAM and 256-QAM, and the upstream ports support QPSK, 8-QAM, 16-QAM, 32-QAM, and 64-QAM modulation, depending on the upstream's mode of operation.
These new cable interface line cards are part of the new Broadband Processing Engine (BPE) series of cable interfaces that are available for the Cisco uBR7246VXR universal broadband router. The BPE cards provide increased performance and advanced Radio Frequency (RF) management, as well as innovative, integrated tools for sophisticated content, traffic and network management.
Note See the "Upstream Modulation Type Mismatch Can Cause Modems to Go Offline When Using Cisco uBR-MC16U/X and Cisco uBR-MC28U/X Cards" section for important configuration information on these new cards.
Line Card Models
The new cards come in two versions, the "U" and the "X" versions, which are identical except for the type of upconverter that the downstream ports use:
•Cisco uBR-MC16U (part number UBR-MC16U) and Cisco UBR-MC28U card (part number UBR-MC28U)—Each downstream port includes an onboard integrated upconverter that generates an RF signal suitable for connection to a combiner and transmission on the coaxial cable network, without the need for any external upconverters. This can save both the money and rack space required by an external upconverter, as well as reduce the complexity of the equipment at the headend site.
•Cisco uBR-MC16X (part number UBR-MC16X) and Cisco uBR-MC28X card (part number UBR-MC28X)—The downstreams on these cards do not include integrated upconverters. Instead, the downstream ports generate an IF signal that must be converted through an external upconverter before transmission on the cable network. This allows these cards to easily replace existing line card installations that currently use external upconverters.
Modes of Operation
Depending on the configuration, the Cisco uBR-MC16U/X and Cisco uBR-MC28U/X line cards support either DOCSIS or Euro-DOCSIS operation in one of the following operational modes:
•TDMA-only mode, which supports only DOCSIS 1.0 and DOCSIS 1.1 cable modems.
•A-TDMA-only mode, which supports DOCSIS 2.0 cable modems.
•Mixed TDMA/A-TDMA mode, which supports both DOCSIS 1.0/DOCSIS 1.1 and DOCSIS 2.0 cable modems on the same upstream.

New Software Features in Release 12.2(15)CX
DOCSIS 2.0 A-TDMA Support
The Cisco uBR-MC16U/X and Cisco uBR-MC28U/X cards improve the maximum upstream bandwidth on existing DOCSIS 1.0 and DOCSIS 1.1 cable networks by providing a number of advanced PHY capabilities that have been specified by the new DOCSIS 2.0 specifications.
The DOCSIS 2.0 A-TDMA Support feature incorporates the following advantages and improvements of DOCSIS 2.0 networks:
•Builds on existing DOCSIS cable networks by providing full compatibility with existing DOCSIS 1.0 and DOCSIS 1.1 cable modems. (The registration response (REG-RSP) message contains the DOCSIS version number to identify each cable modem's capabilities.)
•Upstreams can be configured for three different modes to support different mixes of cable modems:
–An upstream can be configured for TDMA mode to support only DOCSIS 1.0 and DOCSIS 1.1 cable modems.
–An upstream can be configured for A-TDMA mode to support only DOCSIS 2.0 cable modems.
–An upstream can be configured for a mixed, TDMA/A-TDMA mode, to support both DOCSIS 1.0/DOCSIS 1.1 and DOCSIS 2.0 cable modems on the same upstream.
Note DOCSIS 2.0 A-TDMA cable modems will not register on a TDMA upstream if an A-TDMA or mixed upstream exists in the same MAC domain, unless the CMTS explicitly switches the cable modem to another upstream using an Upstream Channel Change (UCC) message. DOCSIS 1.0 and DOCSIS 1.1 cable modems cannot register on an A-TDMA only upstream.
•A-TDMA mode defines new interval usage codes (IUC) of A-TDMA short data grants, long data grants, and Unsolicited Grant Service (UGS) grants (IUC 9, 10, and 11) to supplement the existing DOCSIS 1.1 IUC types
•Increases the maximum channel capacity for A-TDMA upstreams to 30 Mbps per 6 MHz channel.
•A-TDMA and mixed modes of operation provide higher bandwidth on the upstream using new 32-QAM and 64-QAM modulation profiles. In addition, an 8-QAM modulation profile is supported.
•Supports a minislot size of 1 tick for A-TDMA operations.
•Increases channel widths to 6.4 MHz (5.12 Msymbol rate).

New Hardware Features in Release 12.2(11)CX
Support for the NPE-G1 in the Cisco uBR7246VXR
Cisco IOS Release 12.2(11)CX introduces support for the Network Processing Engine NPE-G1 (NPE-G1) in the Cisco uBR7246VXR universal broadband router. NPE-G1 addresses the demand for performance and flexibility by doubling its processing capacity and enabling unprecedented LAN performance.
The NPE-G1 offers the following benefits:
•Provides performance of up to 1 million packets per second (PPS) in Cisco Express Forwarding (CEF) switching.
•Offers three Gigabit Ethernet/Fast Ethernet ports that do not take up bandwidth points
•Doubles the amount of available DRAM (to 1 GB)
•Eliminates the requirement for an input/output (I/O) controller
•Eliminates I/O controller LAN interface bandwidth points
•Provides modular processors and the ability to upgrade
•Offers improved price performance
Note The Cisco 7200 VXR and Cisco uBR7246VXR routers use different models of the NPE-G1 processor. For the Cisco 7200 VXR, order the NPE-G1 or NPE-G1= product. For the Cisco uBR7246VXR router, order the UBR7200-NPE-G1 or UBR7200-NPE-G1= product. Unless otherwise indicated, all references to the NPE-G1 in this document also refer to UBR7200-NPE-G1.
The NPE-G1 is the first network processing engine for the Cisco uBR7246VXR router to provide the functionality of both a network processing engine and I/O controller. If used without an I/O controller, an I/O blank panel must be in place.
While its design provides I/O controller functionality, it can also work with any I/O controller supported in the Cisco uBR7246VXR router. The NPE-G1, when installed with an I/O controller, provides the bootflash and NVRAM that the Cisco IOS software uses to boot.
Note An I/O controller can be used with the NPE-G1, but an I/O controller is not necessary for system functionality. Installing an I/O controller in a chassis with the NPE-G1 activates the console and auxiliary ports on the I/O controller and automatically disables the console and auxiliary ports onboard the NPE-G1. However, you can still use the Flash disk slots and Ethernet ports on both the NPE-G1 and I/O controller when both cards are installed.
The NPE-G1 maintains and executes the system management functions for the Cisco uBR7246VXR routers and also holds the system memory and environmental monitoring functions.
The NPE-G1 consists of one board with multiple interfaces. The NPE-G1 consists of the following components:
•BCM1250 system
–Microprocessor operates at an internal clock speed of 700 MHz.
–Hardware logic to interconnect the processor, DDR-SDRAM (double data rate synchronous dynamic random-access memory), LDT (lightning data transport) bus, the generic PCI bus, and three direct-interface Gigabit Ethernet interfaces.
•Cache memory
The NPE-G1 has two levels of cache: primary and secondary cache that are internal to the microprocessor with secondary unified cache for data and instruction.
•The NPE-G1 uses DDR-SDRAM for providing code, data, and packet storage.
•Two environmental sensors for monitoring the cooling air as it enters and leaves the chassis.
•Full-feature I/O controller functionality
–Three Gigabit Ethernet interfaces (six ports: three GBIC [optical] and three RJ-45s [copper]). Any three ports are available at the same time and are linked directly to the BCM1250 system; therefore the interfaces are not charged bandwidth points.
–Compact Flash Disk for storing the default Cisco IOS software image. The compact Flash Disk slot can be used whether or not an I/O controller is in the router.
–Auxiliary port with full data terminal equipment (DTE) functionality. (Functional when an I/O controller is not present. If an I/O controller is present, its auxiliary port is the default port.)
–Console port with full data communications equipment (DCE) functionality. (Functional when an I/O controller is not present. If an I/O controller is present, its console port is the default port.)
–Boot ROM for storing sufficient code for booting the Cisco IOS software.
–Flash memory for storing the boot helper (boot loader) image. (The boot helper image comes installed on the NPE-G1.) If an I/O controller is present, its Flash memory is no longer available.
–NVRAM for storing the system configuration and environmental monitoring logs. NVRAM uses lithium batteries to maintain its contents when disconnected from power. If an I/O controller is present, its NVRAM memory is no longer available.
–Upgradable memory modules.

There are no new software features in Cisco IOS Release 12.2(11)CX.
Important Notes
The following sections contain important notes about Cisco IOS Release 12.2(15)CX1 that apply to Cisco uBR7200 series universal broadband routers.
Removing Previous Default Modulation Profiles When Upgrading to Cisco IOS Release 12.2(15)CX1
When upgrading to Cisco IOS Release 12.2(15)CX1, remove the previous default modulation profiles in order for to get the optimized default modulation profiles from the rebuild image. The older 41/141/241 modulation profiles would not give optimized channel utilization, although they won't create an upstream hang problem, as the driver code safety check the guard time internally and overwrite the value if necessary.
When upgrading to Cisco IOS Release 12.2(15)CX1 from 12.2(15)CX, you need to force the Cisco uBR7246VXR router to regenerate the default modulation profiles for the Cisco uBR-MC16U/X and Cisco uBR-MC28U/X cable interface line cards. To do this, give the following commands at the global configuration mode prompt:
no cable modulation profile 41
no cable modulation profile 141
no cable modulation profile 241
Upstream Modulation Type Mismatch Can Cause Modems to Go Offline When Using Cisco uBR-MC16U/X and Cisco uBR-MC28U/X Cards
Caveat CSCec40125, All modems on upstream go offline and do not return, describes a situation in which all cable modems on an upstream on a Cisco uBR-MC16U/X or Cisco uBR-MC28U/X card can go offline and do not come back online until the upstream is shut down and reenabled, using the shutdown and no shutdown commands. To avoid this problem, use the following workaround until this caveat is resolved:
Step 1 Configure the guard time on each modulation profile being used on the Cisco uBR-MC16U/X or Cisco uBR-MC28U/X card so that the guard time on short burst profiles is set to 26 symbols and the guard time for long burst profiles is set to 168 symbols. For example:
Router# configure terminalRoute(config)# cable modulation-profile profile-id short 4 76 30 26 qpsk scrambler 152 no-diff 68 shortenedRouter(config)# cable modulation-profile profile-id long 8 232 0 168 qpsk scrambler 152 no-diff 100 shortenedRouter(config)#
Note The above values are for the default recommended symbols/minislot size of 32 for all channel widths.
Step 2 If using the ingress noise cancellation feature, change the noise cancellation value to 198 for odd port numbers and to 200 for even upstream port numbers. For example, on a Cisco uBR-MC16U card in slot 4/0, you would give the following commands:
Router# configure terminalRouter(config)# interface cable 4/0Router(config-if)# cable upstream 0 ingress-noise-cancellation 200Router(config-if)# cable upstream 2 ingress-noise-cancellation 200Router(config-if)# cable upstream 4 ingress-noise-cancellation 200Router(config-if)# cable upstream 1 ingress-noise-cancellation 198Router(config-if)# cable upstream 3 ingress-noise-cancellation 198Router(config-if)# cable upstream 5 ingress-noise-cancellation 198Router(config-if)#
Upgrading When Using Shared Secret Passwords
Cisco IOS Release 12.2 BC changed the encryption algorithm used for the shared-secret command. If you are upgrading from Cisco IOS Release 12.1 EC or Cisco IOS Release 12.0 SC, you cannot cut and paste the "shared-secret" configuration lines that include an encrypted password. Instead, you must re-enter the original shared secret passwords at the CLI prompt.
For example, if the actual shared secret password is "cm-sharedsecret-password," you would enter the cable shared-secret cm-sharedsecret-password command at the CLI prompt. If you have enabled password encryption, the configuration file will then show only the newly encrypted password.
The following example shows a typical configuration session:
Router# config t
Router(config)# service password-encryption
Router(config)# int c6/0
Router(config-if)# cable shared-secret cm-sharedsecret-password
Router(config-if)# exit
Router(config)# exit
Router# show running-config | include sharedcable shared-secret 7 0458064B1C294D5C0C1D161211190910673B253B20222D0103Router#
Note This change only affects the encryption of the passwords that are stored in the configuration file. It does not affect the actual encryption that is used between the CMTS and CMs, so you do not need to change the shared secret in the DOCSIS configuration files for the CMs.
Using the show cable modem Command After an HCCP Switchover
If you are using HCCP 1+1 or N+1 redundancy, the new primary processor after a switchover automatically creates a new database of the online cable modems. This means that the show cable modem ip-address and show cable modem ip-address cnr commands might not show a particular cable modem until the CMTS receives IP traffic from that cable modem.
You can force IP traffic by using the ping ip-address command, and then the show cable modem ip-address and show cable modem ip-address cnr commands will show the cable modem. You can also display any particular cable modem by using the show cable modem | include ip-address command.
Maximum Baud Rate on Aux Port for I/O-2FE/E Controller
The Auxiliary Port (AUX) on the Cisco UBR7200-I/O-2FE/E input/output controller for the Cisco uBR7246VXR router supports a maximum baud rate of 19,200 bps. The CLI commands will allow you to set the baud rate for the AUX port to 38,4000 bps, but you will be unable to communicate at this speed. Therefore, set the baud rate for the AUX port to 19,200 bps or less.
SNR Algorithm Updated
Since Cisco IOS Release 12.2(4)BC1, the algorithm for calculating the SNR estimate in the show controllers cable upstream command was refined for a more accurate value. The new SNR estimate uses the algorithm as recommended by the chip manufacturer, and depending on plant characteristics, the new SNR value could be up to 6 dB lower than the values shown in earlier software releases.
Note This value is only an estimate—for the most accurate value, use specialized test equipment like a spectrum analyzer.
Avoiding the Dropping of SNMP Traps
When the snmp-server enable traps command is given without any options, it enables all traps, which can generate a significant number of traps at key events, such as system power-up. If the SNMP queue is not large enough to handle all of the traps, new traps will be dropped without notification until the existing traps are sent and slots become available in the queue.
You can do two things to avoid dropping traps in this situation:
•Increase the SNMP trap queue size. The default queue size is 10, which is insufficient to handle all traps. Use the snmp-server queue-length length global configuration command to increase the queue size. The length parameter can range from 10 to 1000. Increase the queue size until traps are no longer dropped.
•Disable unneeded SNMP traps. For example, if you do not need SYSLOG traps (which are sent for every message displayed on the console), disable those traps as follows:
router(config)# snmp-server enable trapsrouter(config)# no snmp-server enable traps syslogDOCSIS 1.0 BPI Support
To conform with a recent change in the DOCSIS 1.0 Baseline Privacy Interface (BPI) Specification, Cisco IOS Release 12.2(8)BC1 and later releases require that the Baseline Privacy Configuration Settings Option (Type 17) must be included in the DOCSIS configuration file for all DOCSIS 1.0 cable modems attempting to register for BPI encryption. If the type 17 option is not included, an "Unauthorized SAID" warning will appear in the CMTS console, and the cable modem will not be allowed to come online.
Previous Cisco IOS Releases allowed DOCSIS 1.0 cable modems to register for BPI encryption and to come online, even if the DOCSIS configuration file did not include the type 17 option. The change to the DOCSIS BPI specification, however, made the type 17 option mandatory for BPI operation.
For more information about this requirement, see the TAC technical note on Cisco.com at http://www.cisco.com/warp/public/109/bpi_changes_23895.html.
Limitation on Vendor-Specific Information in the DOCSIS Configuration File
DOCSIS requires that when the cable modem sends its Registration Request (REG-REQ) message to the CMTS, it must include the configuration information found in the DOCSIS configuration file. This configuration information must include all vendor-specific information fields (VSIF). Because MAC-layer management messages, such as REG-REQ, have a maximum data size of 1522 bytes, this limits the amount of VSIF information that can be included in the DOCSIS configuration file.
In particular, the maximum packet size imposes a limit on the number of Cisco IOS CLI commands you can include as VSIF fields in the DOCSIS configuration file. The exact number of commands that will fit depends on the other information included in the file, as well as the length of each command.
If the REG-REQ message is larger than 1522 bytes, the cable modem will likely report errors similar to the following errors that appears on Cisco uBR900 series cable access routers:
%LINK-4-TOOBIG: Interface cable-modem0, Output packet size of 1545 bytes too big%LINEPROTO-5-UPDOWN: Line protocol on Interface cable-modem0, changed state to downIn addition, the CMTS will also report that the cable modem timed out during the registration process. If this occurs, you can try the following steps:
•Reduce the length of the commands by using the abbreviated form of the command. For example, you can specify the int c0 instead of the full command interface cable-modem0.
•SNMP MIB objects are not included in the Registration Request message, so wherever possible, replace the CLI commands with the corresponding SNMP MIB object statements in the DOCSIS configuration file.
•If a large number of CLI commands must be given, use VSIF option 128 to download a Cisco IOS configuration file to the cable modem.
For complete details on what is included in the REG-REQ message, see Chapter 6 of the current DOCSIS 1.1 specification (SP-RFIv1.1-I07-010829 or later).
Note This limitation is being tracked by caveat CSCdv83892 but is not expected to be resolved unless the DOCSIS specification is changed to remove the maximum size limit for MAC-layer management messages.
Configuring the Routing Protocol Causes a Reset of the Cable Modems
Be aware that when configuring a routing protocol on a Cisco uBR7200 series router, the Cisco IOS software must reset the interfaces to enable the change. This normally does not significantly affect operations on the interface, except that when this is done on a cable interface, it causes all cable modems on that particular downstream to reinitialize, potentially interfering with data transmission on that downstream. Therefore, you should use the routing protocol global configuration commands, such as router rip, only when a minimum of subscribers would be affected.
Cable 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. You can bundle all cable interfaces on a Cisco CMTS into a single bundle.
Note Cable interface bundling is applicable only in two-way cable configurations. It is not supported in telco-return configurations.
Using the CLI, first configure a master interface for a cable interface bundle. The master interface has an IP address assigned and is visible for IP routing functionality. After you configure the master interface, add additional cable interfaces to the same interface bundle. Those interfaces must not have an IP address assigned. You can also configure multiple bundle interfaces.
Use the following commands to configure and view cable interface bundles:
[no] cable bundle n master
show cable bundle
Up to four interface bundles can be configured. In each bundle, specify exactly one interface 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 [1]. The subinterface number starts from 1.
Caution Configure an IP address on the master interface only. An attempt to add an interface to a bundle will be rejected if an IP address is configured and the interface is not specified as a master interface.
When bundling cable interfaces, only the interface configured to be the bundle master is allowed to have subinterfaces. An interface that has subinterface(s) defined over it will not be allowed to be part of a bundle. MIB objects on cable interface bundles are not supported as of the date of this publication.
For more information on cable bundling, see the chapter "Understanding System Operations" of the
Cisco uBR7200 Series Software Configuration Guide and the Cable Interface Bundling for the Cisco uBR7200 Series Cable Router feature module. For information on feature modules, see the "Feature Modules" section.EIGRP, IS-IS, and OSPF Not Supported on Cable Interfaces
The Cisco uBR7200 supports advanced routing protocols such as Enhanced Interior Gateway Routing Protocol (EIGRP), Intermediate System-to-Intermediate System (IS-IS), and Open Shortest Path First (OSPF) only on the WAN interfaces, not on the cable interfaces. On cable interfaces, use a routing protocol that is supported by the cable modems, such as RIPv2.

MIBs
Current MIBs
To obtain lists of supported MIBs by platform and Cisco IOS release, and to download MIB modules, go to the Cisco MIB web site on Cisco.com at http://www.cisco.com/public/sw-center/netmgmt/cmtk/mibs.shtml.
Supported MIBs
The Cisco uBR7200 series universal broadband routers support the following categories of MIBs:
•SNMP standard MIBs—These MIBs are required by any agent supporting SNMPv1 or SNMPv2 network management.
•Cisco's platform and network-layer enterprise MIBs—Common across most of Cisco's router platforms. If your network management applications are already configured to support other Cisco routers, such as the 2600 series or 7200 series, no further configuration is needed unless the version of Cisco IOS software being used has updated these MIBs.
•Cable-specific MIBs—Provide information about the cable interfaces and related information on the uBR7200 series routers. They include both DOCSIS-specific MIBs and Cisco-specific enterprise MIBs. If your network management applications have not already been configured for the uBR7200 series routers, these MIBs must be loaded.
•Deprecated MIBs—Supported in earlier releases of Cisco IOS software but have been replaced by more standardized, scalable MIBs. Network Management applications and scripts should convert to the replacement MIBs as soon as possible.
For information on the SNMP standard MIBs and Cisco's platform and network-layer enterprise MIBs, see Cisco's MIB web site at http://www.cisco.com/public/sw-center/netmgmt/cmtk/mibs.shtml.
The cable-specific MIBs are described in the following section.
Cable-Specific MIBs
Table 8 shows the cable-specific MIBs that are supported on the Cisco uBR7200 series universal broadband routers. The table also provides a brief description of each MIB's contents and the Cisco IOS Software Release in which the MIB was initially functional—earlier releases might have had unsupported prototype versions of the MIB; later releases might have added new attributes and functionality. Because of interdependencies, the MIBs must be loaded in the order given in the table.
Note The names given in Table 8 are the filenames for the MIBs as they exist on Cisco's FTP site (ftp://ftp.cisco.com/pub/mibs/ or http://www.cisco.com/public/mibs). Most MIBs are available in both SNMPv1 and SNMPv2 versions; the SNMPv1 versions have V1SMI as part of their filenames.
Deprecated MIBs
Old Cisco MIBs will be replaced in a future release. Currently, OLD-CISCO-* MIBs are being converted into more scalable MIBs without affecting existing Cisco IOS products or network management system (NMS) applications. You can update from deprecated MIBs to the replacement MIBs as shown in Table 9.
Note Some of the MIBs listed in Table 9 represent feature sets that are not supported on Cisco uBR7200 series universal broadband routers.

A Cisco device running IOS and enabled for the Border Gateway Protocol (BGP) is vulnerable to a Denial of Service (DOS) attack from a malformed BGP packet. The BGP protocol is not enabled by default, and must be configured in order to accept traffic from an explicitly defined peer. Unless the malicious traffic appears to be sourced from a configured, trusted peer, it would be difficult to inject a malformed packet. BGP MD5 is a valid workaround for this problem.
Cisco has made free software available to address this problem. For more details, please refer to this advisory, available at http://www.cisco.com/warp/public/707/cisco-sa-20040616-bgp.shtml.

Cisco Feature Navigator
Cisco IOS software is packaged in feature sets that are supported on specific platforms. To get updated information regarding platform support for this feature, access Cisco Feature Navigator. Cisco Feature Navigator dynamically updates the list of supported platforms as new platform support is added for the feature.
Cisco Feature Navigator is a web-based tool that enables you to quickly determine which Cisco IOS software images support a specific set of features and which features are supported in a specific Cisco IOS image. You can search by feature or release. Under the release section, you can compare releases side by side to display both the features unique to each software release and the features in common.
To access Cisco Feature Navigator, you must have an account on Cisco.com. If you have forgotten or lost your account information, send a blank e-mail to cco-locksmith@cisco.com. An automatic check will verify that your e-mail address is registered with Cisco.com. If the check is successful, account details with a new random password will be e-mailed to you. Qualified users can establish an account on Cisco.com by following the directions found at this URL:
Cisco Feature Navigator is updated regularly when major Cisco IOS software releases and technology releases occur. For the most current information, go to the Cisco Feature Navigator home page at the following URL:

Technical Assistance Center
The Cisco Technical Assistance Center (TAC) is available to all customers who need technical assistance with a Cisco product, technology, or solution. Two levels of support are available: the Cisco TAC Web Site and the Cisco TAC Escalation Center.
Cisco TAC inquiries are categorized according to the urgency of the issue:
•Priority level 4 (P4)—You need information or assistance concerning Cisco product capabilities, product installation, or basic product configuration.
•Priority level 3 (P3)—Your network performance is degraded. Network functionality is noticeably impaired, but most business operations continue.
•Priority level 2 (P2)—Your production network is severely degraded, affecting significant aspects of business operations. No workaround is available.
•Priority level 1 (P1)—Your production network is down, and a critical impact to business operations will occur if service is not restored quickly. No workaround is available.
The Cisco TAC resource that you choose is based on the priority of the problem and the conditions of service contracts, when applicable.
Cisco TAC Web Site
You can use the Cisco TAC Web Site to resolve P3 and P4 issues yourself, saving both cost and time. The site provides around-the-clock access to online tools, knowledge bases, and software. To access the Cisco TAC Web Site, go to this URL:
All customers, partners, and resellers who have a valid Cisco service contract have complete access to the technical support resources on the Cisco TAC Web Site. The Cisco TAC Web Site requires a Cisco.com login ID and password. If you have a valid service contract but do not have a login ID or password, go to this URL to register:
http://www.cisco.com/register/
If you are a Cisco.com registered user, and you cannot resolve your technical issues by using the Cisco TAC Web Site, you can open a case online by using the TAC Case Open tool at this URL:
http://www.cisco.com/tac/caseopen
If you have Internet access, we recommend that you open P3 and P4 cases through the Cisco TAC Web Site.
Cisco TAC Escalation Center
The Cisco TAC Escalation Center addresses priority level 1 or priority level 2 issues. These classifications are assigned when severe network degradation significantly impacts business operations. When you contact the TAC Escalation Center with a P1 or P2 problem, a Cisco TAC engineer automatically opens a case.
To obtain a directory of toll-free Cisco TAC telephone numbers for your country, go to this URL:
