Introduction
For information on new features and Cisco IOS commands supported by Cisco IOS Release 12.1 XQ, see the "New and Changed Information" section and the "Related Documentation" section.
The Cisco uBR7200 Series Universal Broadband Routers—the Cisco uBR7223, the Cisco uBR7246, and the Cisco uBR7246 VXR—are based on the Data Over Cable Service Interface Specification (DOCSIS) standards. Each is designed to be installed at a service provider's headend facility.
Cisco uBR7200 Series Universal Broadband Routers allow two-way transmission of digital data and Voice over IP (VoIP) traffic over a hybrid-fiber coaxial (HFC) network. These routers function as the cable modem termination system (CMTS) for subscriber-end devices such as Cisco uBR904 and Cisco uBR924 Cable Access Routers, and other DOCSIS-compliant cable modems (CMs) and set top boxes (STBs).
For cable plants not fully upgraded to support two-way cable transmission, the routers support DOCSIS-compliant telco return, where the cable modem's return path to the CMTS is via a dial-up telephone line connection instead of an upstream channel over the coaxial cable. The telco-return delivery mechanism enables cable operators to accelerate deployment of high-speed data services before the cable systems are upgraded to two-way plants.
The introduction of the WT2700 Wireless Technology Suite also allows the Cisco uBR7246 VXR, Cisco uBR7246, and Cisco uBR7223 Universal Broadband Routers to become either a two-way high-speed point-to-point wireless system that provides fixed, dedicated wireless links from one headend site to another, or a two-way high-speed multipoint wireless system that provides fixed, dedicated wireless links from one headend site to multiple subscriber units.
The point-to-point link delivers full-duplex data in the unlicensed U-NII band (5.725 to 5.825 GHz). The multipoint link delivers full-duplex data in the licensed Multichannel Multipoint Distribution Service (MMDS) band (2.150 to 2.162 GHz and 2.500 to 2.690 GHz). The WT2700 Wireless Technology Suite includes the wireless modem card, which is installed in the Cisco uBR7200 series chassis, and the Cisco WT2772 wireless transverter, duplexer, and power feed panel, which are external components.
The Cisco uBR7200 series routers support Internet Protocol (IP) routing with a wide variety of protocols and combinations of Ethernet, Fast Ethernet, Gigabit Ethernet, serial, High-Speed Serial Interface (HSSI), Packet over SONET (POS) OC-3 and OC-12c, and Asynchronous Transfer Mode (ATM) media.
Cisco IOS Release 12.1(3) XQ4 supports cable and fixed wireless system configurations using the Cisco uBR7246 VXR, Cisco uBR7246, and Cisco uBR7223.

•
k1 = DOCSIS Baseline Privacy, which is subject to export controls
•
s = "Plus" features: NAT and Inter-Switch Link (ISL)
Note
All Cisco IOS Release 12.1(3) XQ4 images require 64 MB of DRAM. 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 radio frequency (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 "k1" 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 via 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 VPN support.
–
Telco-return CMs—To support telco return, use a Cisco uBR7200 series software image that contains "t" in its file name. The telco return CM must be DOCSIS-based or compliant, and must be configured to support telco return.
Note
Some third-party telco-return CMs cannot receive traffic over the same downstream channel as CMs operating on a two-way data system. In these instances, segment your cable plant to allow more than one downstream channel.
–
EuroDOCSIS CMs or set top boxes (STBs) with integrated EuroDOCSIS CMs using Cisco MC16E Cable Modem Cards and Cisco IOS Release 12.1(1a)T1 or higher. EuroDOCSIS operation support includes 8 MHz Phase Alternating Line (PAL) or Systeme Electronique Couleur Avec Memoire (SECAM) channel plans.
•
DOCSIS 1.0 Extensions
The Cisco uBR7200 series support DOCSIS 1.0 QoS extensions that include:
–
Multi-SID support, allowing the definition of multiple Service IDs (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 non-zero 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 (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 via dynamic MAC messages or the feature set. If the CMs in your network are pure DOCSIS 1.0-based, they will 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 uBR7246 VXR chassis must be used. The Cisco uBR7246 VXR must contain a clock card and an MC16S or MC16E Cable Modem Card. Only the MC16S and the MC16E Cable Modem Cards support the external clock reference from the clock card to distribute that signal to CMs or set top boxes (STBs) attached to the specific network segments. The chassis must be running Cisco IOS Release 12.1(1a)T1 or higher.
Each cable modem must also support VoIP applications and the clock reference feature set to enable synchronized timing. The Cisco uBR924 Cable Access Router, running Cisco IOS Release 12.0(7)T or later, supports clock automatically.

Determining Your Software Release
To determine the version of Cisco IOS software running on the Cisco uBR7200 Series Universal Broadband Router, log in to the router and enter the show version EXEC command:
Router> show versionCisco Internetwork Operating System SoftwareIOS (tm) 12.1 XQ Software (ubr7200-is-mz), Version 12.1(3) XQ4, RELEASE SOFTWAREUpgrading to a New Software Release
For general information about upgrading to a new software release, see Cisco IOS Upgrade Ordering Instructions located at http://www.cisco.com/warp/public/cc/cisco/mkt/ios/prodlit/957_pp.htm.
The multipoint wireless modem card (uBR-MCW-MDA) for the Cisco uBR7200 Series Universal Broadband Router requires a microcode bundle (RHE) to allow it to operate.
Microcode software images ship in Flash memory along with the system software image. When the router starts, the system software unpacks the microcode software bundle and loads the proper software on all the interface linecards.
It is possible to use a later version of microcode software than the one shipped with the Cisco IOS software from the factory. The microcode software in Flash memory is mapped to the linecards.
The microcode bundle for the multipoint wireless modem card is downloadable (with a Cisco.com login) at http://www.cisco.com/cgi-bin/tablebuild.pl/rhe.
Note
Unless you fully understand how Cisco IOS software uses microcode software, it is important to keep the factory configuration.
Feature Set Tables
The Cisco IOS software is packaged in feature sets consisting of software images—depending on the platform. Each feature set contains a specific set of Cisco IOS features.
Cisco IOS Release 12.1(3) XQ4 supports the same feature sets as Cisco IOS Release 12.1(3)T, but adds new features supported by the Cisco uBR7200 series.
Table 7 lists the features and feature sets supported by the Cisco uBR7200 series in Cisco IOS Release 12.1(3) XQ4 and uses the following conventions:
•
Yes—The feature is supported in the software image.
•

New Hardware Features in Release 12.1(3)XQ
The following new hardware features are supported by the Cisco uBR7200 series in Cisco IOS Release 12.1(3)XQ.
Multipoint Wireless Modem Card
The multipoint wireless modem card installs in a modem card slot of a Cisco uBR7246 VXR, Cisco uBR7246, or Cisco uBR7223 router. It is configured through the router's system console or via the CiscoView network management system. The multipoint wireless modem card provides the control and data interface to the system's digital motherboard and the RF subsystem in the wireless transverter. It also provides the up/down conversion from baseband to intermediate frequency (IF).
A Cisco uBR7200 series router configured with a multipoint wireless modem card provides fixed dedicated wireless links from one site to multiple subscriber units.
For more information on the multipoint wireless modem card, including detailed installation information, see the Cisco uBR7200 Series Router Multipoint Wireless Modem Card and Subsystem Installation guide.
Power Feed Panel
The power feed panel serves as an interconnection device between the multipoint wireless modem card, the wireless transverter, and a -48 VDC power supply. The main purpose of this unit is to provide DC power to the system, provide control signals to the wireless transverter, and transmit and receive IF signals to and from the transverters. In addition, the unit contains circuit breakers for the DC power.
At least one power feed panel is required for each installation. Each power feed panel supports a maximum of four wireless transverters.
For more information about the power feed panel, including detailed installation information, see the Cisco uBR7200 Series Router Multipoint Wireless Modem Card and Subsystem Installation guide.
MMDS Wireless Transverter and Duplexer Assembly
The ruggedized wireless transverter is the outdoor data interface to the indoor subsystems. It provides up/down conversion from IF to RF frequencies. One of the transverter's components is the duplexer assembly with antenna connection. The duplexer assembly acts as a filter for transmit and receive isolation. For more information about the wireless transverter and duplexer assembly, including detailed installation information, see the Cisco uBR7200 Series Router Multipoint Wireless Modem Card and Subsystem Installation guide.
New Software Features in Release 12.1(3)XQ
The following new software features are supported by the Cisco uBR7200 Series Universal Broadband Routers in Cisco IOS Release 12.1(3)XQ.
Support for Fixed Wireless Multipoint
The Cisco high-speed multipoint broadband fixed wireless system provides dedicated, full-duplex, wireless data communication between a single headend site and multiple subscriber sites. It transmits and receives in the licensed Multichannel Multipoint Distribution Service (MMDS) band (2.150 to 2.162 GHz and 2.500 to 2.690 GHz).
Support for fixed wireless multipoint allows the Cisco uBR7246 VXR, Cisco uBR7246, and Cisco uBR7223 to function as the headend of a Cisco broadband fixed wireless point-to-multipoint system, which is designed to use antennas that broadcast the RF signal in a portion of a complete circle, or directionally, in what is called a sector. Each headend site can be designed and configured to broadcast in a single sector, or in multiple sectors, depending on the requirements of the network.
For each sector, the components of a point-to-multipoint headend system consist of the necessary cables and:
•
One Cisco uBR7246 or Cisco 7223 Universal Broadband Router
•
One wireless modem card installed in the router
•
One power-feed panel
•
One or two antennas (a second antenna for diversity reception is optional)
•
One or two wireless transverters containing the RF amplifier (one for each antenna)
•
One or two duplexers (one for each wireless transverter)
On the subscriber side, a Cisco 2600 series modular access router or a Cisco 3600 series modular high-density access router is a required component of the subscriber unit system, which is designed to receive RF signals from the headend and transmit return-RF signals to the headend.
The fixed wireless point-to-multipoint system incorporates Vector Orthogonal Frequency Division Multiplexing (VOFDM), so it does not always depend on line-of-sight (LOS) deployment. With VOFDM, the system allows wireless operation in obstructed, non-line-of-sight (non-LOS) environments by taking advantage of multipath signals. This can be particularly useful in urban and suburban environments.
For additional information about fixed wireless multipoint support, including information about CLI commands, see the Multipoint Support for the Cisco uBR7200 Series Universal Broadband Router feature module and the Cisco uBR7200 Series Router Multipoint Wireless Modem Card and Subsystem Installation guide.
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 website 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 are the MIBs that 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 and Wireless-specific MIBs—Provide information about the cable and wireless 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.
The and are described in the following sections. For information on the SNMP standard MIBs and Cisco's platform and network-layer enterprise MIBs, see Cisco's MIB website at http://www.cisco.com/public/sw-center/netmgmt/cmtk/mibs.shtml.
Cable-specific and Wireless-specific MIBs
Table 8 shows the cable and wireless MIBs that are supported on the Cisco uBR7200 Series Universal Broadband Routers. The table also provides a brief description of each MIB's contents. 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 and Replacement 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.
Note
Cisco Management Information Base (MIB) User Quick Reference is no longer published. If you have an account with Cisco.com, you can find the current list of MIBs supported by Cisco. To reach the Cisco Network Management Toolkit, go to Cisco.com, press Login, and click to Software Center: Network Mgmt Products: Cisco Network Management Toolkit: Cisco MIB.

CSCdr60827
Some global configuration commands on the Cisco BR7200 series routers can apply to both cable and radio headend line cards. Although such a command has only one internal setting, it does have both a "cable" form and a "radio" form. Either form can be used to change the global setting and both forms can appear in the running configuration. This might be confusing to the user.
The following commands can apply to both cable and radio headend line cards (this list is not exhaustive):
cable time-server
commands that include cable qos
commands that include cable flap-list•
CSCdr97644
Some of the functions in the radio headend system (that is, the Cisco uBR7200 series router)—most notably the RX gain calibration—do not work properly if the upstream channel has been assigned a subchannel, yet is shutdown.
For example, the following commands in the configuration file cause a problem:
radio upstream 1 subchannel 3 modulation-profile 7
radio upstream 1 shutdownThis configuration indicates that the subchannel is assigned but shutdown.
Workaround: If the channel is to be shutdown, the following command should also be entered to remove the subchannel assignment:
router(config-if)# no radio upstream 1 subchannel
The running configuration should be either "unassigned and shutdown" or "assigned and enabled".
Use the following command to unassign and shutdown a subchannel:
radio upstream 1 shutdown
Use the following commands to assign and enable a subchannel:
radio upstream 1 subchannel 3 modulation-profile 7
no radio upstream 1 shutdownResolved Caveats for Release 12.1(3)XQ3
All the caveats listed in this section are resolved in Cisco IOS Release 12.1(3)XQ3. This section describes only severity 1 and 2 caveats and select severity 3 caveats.
•
CSCdr49365
The show radio device access-group command is not yet available. (This command will be available in the next release).
Workaround: Use the show cable device access-group command.
This caveat is resolved in Cisco IOS Release 12.1(3)XQ3.
•
CSCdr82563
The show radio errors command is not yet available.
Workaround: Use the show cable modem error command.
This caveat is resolved in Cisco IOS Release 12.1(3)XQ3 and the show radio errors command is now available.
•
CSCdr86585
On a Cisco uBR7200 series router configured with both a cable modem card and a wireless modem card, issuing the no shutdown command might cause the "Radio link ranging_1" state to last up to 6 minutes before finally establishing the radio link. Normally the "Radio link ranging_1" state should last a few seconds.
Issuing the debug docsis mac log debugging command will show that "CMAC_LOG_RANGING_BACKOFF_SET" is set to a large number (that is, a number above 300).
Workaround: Specify a manual ranging backoff value to shorten the long delay:
radio upstream <mac channel> range-backoff <start><end>Typically, <start> and <end> are numbers less than 10, as in the following syntax example:
radio upstream 0 range-backoff 3 6This caveat is resolved in Cisco IOS Release 12.1(3)XQ3.
•
CSCdr91706 and Cisco IOS HTTP Vulnerability
A defect in multiple releases of Cisco IOS software will cause a Cisco router or switch to halt and reload if the Cisco IOS HTTP service is enabled, browsing to http://router-ip/anytext?/ is attempted, and the enable password is supplied when requested. This defect can be exploited to produce a denial of service (DoS) attack.
The vulnerability, identified as Cisco caveat ID CSCdr91706, affects virtually all mainstream Cisco routers and switches running Cisco IOS software releases 12.0 through 12.1, inclusive. This is not the same defect as CSCdr36952.
The vulnerability has been corrected and Cisco is making fixed releases available for free to replace all affected Cisco IOS releases. Customers are urged to upgrade to releases that are not vulnerable to this defect, as shown in detail below.
This vulnerability can only be exploited if the enable password is known or not set.
You are strongly encouraged to read the complete advisory, which is available at http://www.cisco.com/warp/public/707/ioshttpserverquery-pub.shtml
This caveat is resolved in Cisco IOS Release 12.1(3)XQ3.
•
CSCds00152
When the radio debugging function is enabled via the debug radio command, none of the radio debugging flags appear in the output of the show debug command. This makes it difficult to determine if the radio debugging function is turned on. There is no workaround.
This caveat is resolved in Cisco IOS Release 12.1(3)XQ3.
•
CSCds04747
Cisco IOS software contains a flaw that permits the successful prediction of TCP Initial Sequence Numbers.
This vulnerability is present in all released versions of Cisco IOS software running on Cisco routers and switches. It only affects the security of TCP connections that originate or terminate on the affected Cisco device itself; it does not apply to TCP traffic forwarded through the affected device in transit between two other hosts.
To remove the vulnerability, Cisco is offering free software upgrades for all affected platforms. The defect is described in DDTS record CSCds04747.
Workarounds are available that limit or deny successful exploitation of the vulnerability by filtering traffic containing forged IP source addresses at the perimeter of a network or directly on individual devices.
This notice will be posted at http://www.cisco.com/warp/public/707/ios-tcp-isn-random-pub.shtml.
This caveat is resolved in Cisco IOS Release 12.1(3)XQ3.
•
CSCds32217
Multiple Cisco IOS software and CatOS software releases contain several independent but related vulnerabilities involving the unexpected creation and exposure of SNMP community strings. These vulnerabilities can be exploited to permit the unauthorized viewing or modification of affected devices.
To remove the vulnerabilities, Cisco is offering free software upgrades for all affected platforms. The defects are documented in DDTS records CSCds32217, CSCds16384, CSCds19674, CSCdr59314, CSCdr61016, and CSCds49183.
In addition to specific workarounds for each vulnerability, affected systems can be protected by preventing SNMP access.
This notice will be posted at http://www.cisco.com/warp/public/707/ios-snmp-community-vulns-pub.shtml.
This caveat is resolved in Cisco IOS Release 12.1(3)XQ3.
