This section contains information on the Cisco uBR7200 series routers and Early Deployment Releases (ED) for the Cisco uBR7200 series routers.
For information on new features, see the "New Features in Cisco IOS Release 12.0(2)XC1" section.
The Cisco data-over-cable products---the Cisco uBR7223 universal broadband router, the Cisco uBR7246 universal broadband router, and the Cisco uBR904 cable modem---are compliant with Multimedia Cable Network Partners, Ltd. (MCNS) specifications. MCNS is a consortium of cable television companies whose goal is to create standards for interoperable data over cable systems.
The Cisco uBR7223 is a cost-effective, scalable interface between subscriber cable modems and the backbone data network, and is designed specifically for small to medium-sized network installations. The Cisco uBR7223 is based on the Cisco uBR7246.
The Cisco uBR7246 is the first of data-over-cable products designed to allow two-way transmission of digital data over hybrid fiber-coaxial (HFC) cable. The Cisco uBR7246 supports Internet Protocol (IP) routing with a wide variety of protocols and any combination of Ethernet, Fast Ethernet, High-Speed Serial Interface (HSSI), and Asynchronous Transfer Mode (ATM) media. The Cisco uBR7246 universal broadband router gives cable operators a cost-effective, scalable, and feature-rich interface between subscriber cable modems and the backbone data network.
The Cisco uBR904 cable modem is the subscriber unit, a key component within a cable data system. This subscriber unit functions as an interface between the subscriber's personal computer and the cable operator's network within the subscriber's small office or home office.
For more information on Cisco uBR904, refer to the "Related Documentation" section.

Optional feature set licenses for the Cisco uBR7246 universal broadband router are as follows:
The following sections list the new features supported by the Cisco uBR7246 universal broadband router in Cisco IOS Release 12.0 XC.
The following hardware enhancements were introduced in Cisco IOS Release 12.0(2)XC and are available for the Cisco uBR7200 series router.
For more information refer to the Release Notes for Cisco IOS Release 12.0.
Cisco uBR7246 universal broadband features enable the Cisco uBR7200 universal broadband router to communicate with a hybrid fiber-coaxial (HFC) cable network via a Cisco MC11 cable modem card. Cisco MC11 cable modem cards allow you to connect cable modems on the HFC network to a Cisco uBR7246 in a Community Antenna Television (CATV) headend facility. The modem card provides the interface between the Cisco uBR7246 protocol control information (PCI) bus and the radio frequency (RF) signal on the HFC network.
The Cisco uBR7223 is part of a new class of Cisco data-over-cable products designed to allow two-way transmission of digital data over hybrid fiber-coaxial (HFC) cable. The Cisco uBR7223 supports IP routing with a wide variety of protocols and any combination of Ethernet, Fast Ethernet, High-Speed Serial Interface (HSSI), serial, Packet-Over-SONET (POS), and Asynchronous Transfer Mode (ATM) media.
The Cable Router Line Card (MC16) is available for the Cisco uBR7200. The software for the MC16 card is a driver running on the Cisco uBR7246. Using a PCI interface, the universal broadband router line card software interacts with the MC16 card. Data is passed back and forth, as direct memory access (DMA) transfers, from the Cisco uBR7246 memory to the MC16 card.
Additionally, the MC16 card supports universal broadband router line card management and control with the MC16 MIB, MAC control software and logical link management software based on MCNS standards, and minimized security.
For more information refer to the Update to the Cisco uBR7200 Series Cable Modem Card Installation and Configuration for the MC16A EFT Card publication.
This section contains important information about use of your Cisco IOS Release 12.0 XC software.

This section contains a detailed list of the open and resolved caveats affecting Cisco IOS Release 12.0(2) XC only. For information on other caveats that also apply to this release, refer to the Caveats for Cisco IOS Release 12.0 T document and the Cross-Platform Release Notes for Cisco IOS Release 12.0 document located on CCO and the Documentation CD-ROM.
This section describes possibly unexpected behavior by Release 12.0(2)XC. This section describes only severity 1 and 2 caveats.
Description: If a User Datagram Protocol (UDP) packet with an invalid length is sent to port 514 (the "syslog" port) on an IOS device, the device is likely to reload. In this situation, a stack trace might not be saved. Such packets are sent by the popular nmap port scanning program.
Workaround: You can work around this vulnerability by preventing any affected Cisco IOS device from receiving or processing UDP datagrams addressed to its port 514. This can be done either using packet filtering on surrounding devices, or by using input access list filtering on the affected IOS device itself.
If you use an input access list, that list should be applied to all interfaces to which attackers may be able to send datagrams. This includes not only physical LAN and WAN interfaces, but virtual subinterfaces of those physical interfaces, as well as virtual interfaces and/or interface templates corresponding to GRE, L2TP, L2F, and other tunnelling protocols.
The input access list must block traffic destined for any of the CiscoIOS device's own IP addresses, as well as for any broadcast or multicast addresses on which the Cisco IOS device may be listening. It's important to remember to block old-style "all-zeroes" broadcasts as well as new-style "all-ones" broadcasts.
There is no single input access list that will work in all configurations. It is very important that you understand the effect of your access list in your specific configuration before you activate the list.
The following example shows a possible access list for a three-interface router, along with the configuration commands needed to apply that access list. The example assumes no need for input filtering other than as a workaround for this vulnerability.
! Deny all multicasts, and all unspecified-net broadcasts, to port 514 access-list 101 deny udp any 224.0.0.0 31.255.255.255 eq 514 ! Deny old-style unspecified-net broadcasts access-list 101 deny udp any host 0.0.0.0 eq 514 ! Deny network-specific broadcasts. This example assumes that all of ! the local interfaces are on the class B network 172.16.0.0, subnetted ! everywhere with mask 255.255.255.0. This will differ from network ! to network. Note that we block both new-style and old-style broadcasts. access-list 101 deny udp any 172.16.0.255 0.0.255.0 eq 514 access-list 101 deny udp any 172.16.0.0 0.0.255.0 eq 514 ! Deny packets sent to the addresses of our own network interfaces. access-list 101 deny udp any host 172.16.1.1 eq 514 access-list 101 deny udp any host 172.16.2.1 eq 514 access-list 101 deny udp any host 172.16.3.3 eq 514 ! Permit all other traffic (default would be to deny) access-list 101 permit ip any any
! Apply the access list to the input side of each interface interface ethernet 0 ip address 172.16.1.1 255.255.255.0 ip access-group 101 in
interface ethernet 2 ip address 172.16.2.1 255.255.255.0 ip access-group 101 in
interface ethernet 3 ip address 172.16.3.3 255.255.255.0 ip access-group 101 in
It can be complicated to list all possible addresses, and especially all possible broadcast addresses, to which attack packets might be sent. If you do not expect to receive any legitimate syslog traffic on an interface, you may wish to simply block all syslog traffic arriving on that interface. Remember that this will affect traffic routed through the Cisco IOS device as well as traffic destined to the device.
Input access lists have an impact on system performance, and should be installed with a degree of caution, especially on systems that are running very near their capacity limits.
Description: When you configure Bisync (encapsulation bstun) with the ASCII character set (bsc char-set ascii) on the first port of a serial WIC (1T, 2T, or 2A/S) in WIC slot 0 of a Cisco 2600 series router, only the first character of each frame is received, and the BSTUN tunnel is not established. This only affects Bisync mode when it is configured with the ASCII character set. Other encapsulations are not affected, and using the EBCDIC character set with Bisync works correctly.
Details: For the first serial port in WIC slot 0, the parity detection is not configured correctly for Bisync in ASCII mode. The first character of each frame generates a parity error that causes the receiver to discard the frame after the first character received.
Workaround: Use a different serial port: either the second serial port (port 1) on a 2T or 2A/S WIC in WIC slot 0 or any serial port in WIC slot 1. If you have only one serial WIC, moving it from WIC slot 0 to WIC slot 1 fixes this problem.

Software & Support: Technical Tips (button on left margin)
"Hot Tips" are popular tips and hints gathered from Cisco's Technical Assistance Center (TAC). Most of these documents are also available from the TAC's Fax-on-Demand service. To reach Fax-on-Demand and receive documents at your fax machine, call 888-50-CISCO (888-502-4726).
The following sections are provided from the Technical Tips page:
Cisco Connection Online (CCO) is Cisco Systems' primary, real-time support channel. Maintenance customers and partners can self-register on CCO to obtain additional information and services.
Available 24 hours a day, 7 days a week, CCO provides a wealth of standard and value-added services to Cisco's customers and business partners. CCO services include product information, product documentation, software updates, release notes, technical tips, the Bug Navigator, configuration notes, brochures, descriptions of service offerings, and download access to public and authorized files.
CCO serves a wide variety of users through two interfaces that are updated and enhanced simultaneously: a character-based version and a multimedia version that resides on the World Wide Web (WWW). The character-based CCO supports Zmodem, Kermit, Xmodem, FTP, and Internet e-mail, and it is excellent for quick access to information over lower bandwidths. The WWW version of CCO provides richly formatted documents with photographs, figures, graphics, and video, as well as hyperlinks to related information.
You can access CCO in the following ways:
For a copy of CCO's Frequently Asked Questions (FAQ), contact cco-help@cisco.com. For additional information, contact cco-team@cisco.com.
Cisco documentation and additional literature are available in a CD-ROM package, which ships with your product. The Documentation CD-ROM, a member of the Cisco Connection Family, is updated monthly. Therefore, it might be more current than printed documentation. To order additional copies of the Documentation CD-ROM, contact your local sales representative or call customer service. The CD-ROM package is available as a single package or as an annual subscription. You can also access Cisco documentation on the World Wide Web at http://www.cisco.com, http://www-china.cisco.com, or http://www-europe.cisco.com.
If you are reading Cisco product documentation on the World Wide Web, you can submit comments electronically. Click Feedback in the toolbar and select Documentation. After you complete the form, click Submit to send it to Cisco. We appreciate your comments.
