These release notes are updated as needed to describe new features, memory requirements, hardware support, software platform deferrals, and changes to the microcode or modem code and related documents.
For a list of software caveats that apply to Release 12.0(5)T, see Caveats for Cisco IOS Release 12.0 T that accompanies these release notes. This caveats document is updated for every maintenance release and is located on Cisco Connection Online (CCO) and the Documentation CD-ROM.
Use these release notes with Cross-Platform Release Notes for Cisco IOS Release 12.0 on CCO and the Documentation CD-ROM.
These release notes describe the following topics:
The Cisco uBR904 cable access router gives residential or small office/home office (SOHO) subscribers, high-speed Internet or Intranet access via a shared two-way cable system and IP backbone network. The router connects computers and other customer premise devices at a subscriber site to the service provider's hybrid/fiber coax (HFC) and IP backbone network.
The Cisco uBR904 cable access router interoperates with any bidirectional, DOCSIS-qualified Cable Modem Termination System (CMTS). The Cisco uBR904 ships from the Cisco factory with a Cisco Internetwork Operating System (IOS) software image stored in nonvolatile memory (NVRAM) that supports DOCSIS-compliant bridging data operations. The Cisco uBR904 functions as a cable modem-a modulator/demodulator at a subscriber site to convey data communications on the cable television system.
Based on the feature licenses your company purchased, you can download other Cisco IOS images from CCO. You can configure each Cisco uBR904 cable access router in your network to support special operating modes based on your cable plant's service offering and the practices in place for your network. The Cisco uBR904 can function as an advanced router, providing wide area network (WAN) data connectivity in a variety of configurations.
This section describes the system requirements for Release 12.0 T:

The image subset legend for Tables 1, 2 and 3 appears below:
The Cisco uBR904 cable access router IP routing capabilities conserve IP addresses by using port-level multiplexed Network Address Translation (NAT) and Port Address Translation (PAT). Dynamic Host Configuration Protocol (DHCP) is used to distribute these or real IP addresses to the devices the Cisco uBR904 supports. NAT/PAT is bundled with DHCP server into a feature referred to as "Easy IP."
A boot image supporting DOCSIS-compliant bridging or routing operations ships from the Cisco factory.
 | Caution Cisco IOS images with strong encryption (including, but not limited to, 56-bit data encryption feature sets) are subject to United States government export controls and have limited distribution. Strong encryption images to be installed outside the United States are likely to require an export license. Customer orders may be denied or subject to delay due to Unites States government regulations. When applicable, you must obtain local import and use authorizations for all encryption strengths. Please contact your sales representative or distributor for more information, or send e-mail to export@cisco.com. |

The following section lists the new features supported in Cisco IOS Release 12.0 T.
There are no new hardware features supported by the Cisco uBR904 in Cisco IOS Release 12.0(5)T.
Using previous Cisco IOS images, only 3 PC's can be directly connected to 3 of the 4 Ethernet hub ports at the rear of the Cisco uBR904 and operate correctly in bridging mode. The 3-node directly-connected bridge limit existed due to the MAC chip contained in the unit. The MAC chip reserved 1 filter for the Cisco uBR904's MAC address, leaving 3 available for Ethernet devices.
Cisco IOS 12.0(5)T images contain enhanced software, allowing 1 to 254 PCs to operate in bridging mode. Using Cisco IOS 12.0(5)T images, 4 PCs can be directly connected to 4 Ethernet hub ports or 1 of the 4 ports can be connected to an Ethernet hub, which then connects additional computers or devices at the site. For additional information regarding the bridging operation, see "Bridging Mode" in "Limitations and Restrictions".
There are no new hardware features supported by the Cisco uBR904 in Cisco IOS Release 12.0(4)T.
There are no new software features supported by the Cisco uBR904 in Cisco IOS Release 12.0(4)T.
There are no new hardware features supported by the Cisco uBR904 in Cisco IOS Release 12.0(3)T.
The Cisco IOS Firewall feature set, available for a wide range of Cisco router platforms, adds greater depth and flexibility to existing Cisco IOS software security capabilities, enriching features such as authentication, encryption, and failover with robust firewall functionality and intrusion detection. A Cisco IOS software-based, integrated firewall solution scales to meet the bandwidth and performance requirements of any network. It also maximizes a Cisco router investment by combining multiprotocol routing functionality with sophisticated security policy enforcement throughout the network.
The Cisco IOS Firewall feature set delivers cost-effective perimeter security packaged with advanced features like stateful, application-based filtering, dynamic per-user authentication and authorization, defense against network attacks, Java blocking, and real-time alerts. Because it is completely interoperable with Cisco IOS software features including NAT, VPN tunneling protocols, Cisco Express Forwarding (CEF), AAA extensions, Cisco encryption technology, and Cisco IOS IPSec, It is a complete, integrated VPN solution.
The Cable Device MIB is for DOCSIS-compliant cable modems and Cable Modem Termination Systems (CMTS). The Cable Device MIB records statistics related to the configuration and status of the cable modem. Statistics include an events log and device status. The following list details the components of the Cable Device MIB:
The Cable Device MIB is very similar to the RFI MIB in that both allow access to statistics; they are different in that the Cable Device MIB reports statistics on the Cisco uBR904 cable access router, and the RFI MIB reports statistics on the radio frequency transmissions over the cable television line.
The Cisco Standard MIBs consists of the following components:
The DOCSIS Baseline Privacy feature is based on the DOCSIS Baseline Privacy Interface Specification. It provides data privacy across the HFC network by encrypting traffic flows between the Cisco uBR904 and the cable operator's CMTS.
Baseline Privacy security services are defined as a set of extended services within the DOCSIS MAC sublayer. Two new MAC management message types, BPKM-REQ and BPKM-RSP are employed to support the Baseline Privacy Key Management (BPKM) protocol.
The BPKM protocol does not use authentication mechanisms such as passwords or digital signatures; it provides basic protection of service by ensuring that a cable modem, uniquely identified by its 48-bit IEEE MAC address, can only obtain keying material for services it is authorized to access. The Cisco uBR904 is able to obtain two types of keys from the CMTS: the Traffic Exchange Key (TEK), which is used to encrypt and decrypt data packets, and the Key Exchange Key (KEK), which is used to the decrypt the TEK.
For more information on this feature, refer to the DOCSIS Baseline Privacy Interface Specification (SP-BPI-IO1-970922).
Dynamic Host Configuration Protocol (DHCP) Server:
With the introduction of Easy IP, Cisco IOS Release 12.0(3)T supports Intelligent DHCP Relay and DHCP Client functionality. A DHCP Relay Agent is any host that forwards DHCP packets between clients and servers. A DHCP Relay Agent 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 using standard Cisco IOS IP helper-address functionality.
Network Address Translation and Port Address Translation (NAT/PAT)
Routing protocols will run on the Ethernet interface instead of the cable interface, and all packets received are translated to the correct private network IP address and routed out the Ethernet interface. This eliminates the need to run RIP on the cable interface.
To implement the Cisco uBR904 cable access router, the Ethernet interface is configured with an "inside" address and the cable interface is configured with an "outside" address. The Cisco uBR904 cable access router also supports configuration of static connections, dynamic connections, and address pools.
Full and DOCSIS-Compliant Bridging for the Cisco uBR904 cable access router complies with the DOCSIS standards for interoperable cable modems.
IPSec Network Security (IPSec) is an IP security feature that provides robust authentications and encryption of IP packets. IPSec is a framework of open standards developed by the Internet Engineering Task Force (IETF). IPSec provides security for transmission of sensitive information over unprotected networks such as the Internet. IPSec acts at the network layer, protecting and authenticating IP packets between participating IPSec devices ("peers") such as Cisco uBR904s.
IPSec provides the following network security services:
With IPSec, data can be transmitted across a public network without fear of observation, modification, or spoofing. This enables applications such as virtual private networks (VPNs) and remote user access.
IPSec services are similar to those provided by Cisco Encryption Technology, a proprietary security solution introduced in Cisco IOS Software Release 11.2. However, IPSec provides a more robust security solution, and is standards-based.
Layer 2 Tunneling Protocol (L2TP) is an emerging Internet Engineering Task Force (IETF) standard that combines the best features of two existing tunneling protocols: Cisco's Layer 2 Forwarding (L2F) and Microsoft's Point-to-Point Tunneling Protocol (PPTP). L2TP is an extension to the Point-to-Point Protocol (PPP), which is an important component for Access Virtual Private Networks (VPNs).
Traditional dial-up networking services only supported registered IP addresses, which limited the types of applications that could be implemented over Virtual Private Networks (VPNs). L2TP supports multiple protocols and unregistered and privately administered IP addresses over the Internet. This allows the existing access infrastructure, such as the Internet, modems, access servers, and ISDN terminal adapters (TAs), to be used.
L2TP can be initiated wherever PPTP or L2F is currently deployed and can be operated as a client initiated tunnel, such as PPTP, or a network access server (NAS) initiated tunnel, such as L2F.
Refer to the "Limitations and Restrictions" section for information regarding the functionality of the Cisco uBR904 cable access router in L2TP applications.
The Radio Frequency Interface (RFI) MIB module is for DOCSIS-compliant radio frequency interfaces in cable modems and CMTS. RFI MIB entries provide:
The RFI MIB includes tables describing both the CMTS and the cable modem side of the cable interface. All cable modem tables are implemented.
A routing configuration for the Cisco uBR904 cable access router is most likely used when the cable access router is being added to an existing personal computer network. If set to support routing mode, the Cisco uBR904 cable access router will automatically configure the headend's IP address as its IP default gateway. When the IP host-routing is being configured, this automatic configuration of the headend's IP address as its IP default gateway will allow the Cisco uBR904 cable access router to send packets not intended for the Ethernet interface to the headend.
RIP V2 routing is useful for small internetworks in that it enables optimization of NIC-assigned IP addresses by defining VLSMs for network addresses, and it allows CIDR addressing schema.
This section describes warnings and cautions about using Cisco IOS Release 12.0 T software.
The Cisco uBR904 ships from the Cisco factory with the console port enabled. Based on the standard practices in place for your network, disable the console port as appropriate via the DOCSIS configuration file downloaded to the Cisco uBR904 cable access router. This prohibits network configuration access at the remote site.
For software enhancements when operating in bridging mode, see the "Enhancements to Bridging Operation" section of the New Software Features in Release 12.0(5)T.
The ability of the Cisco uBR904 to grant access to CPE devices is controlled by the "MAX CPE" field in the DOCSIS configuration file. The Cisco uBR904 defaults to one CPE MAC address unless this option is set to a higher number. The valid range using Cisco IOS Release 12.0(5)T or higher images is 1 to 254 for bridging operation; 1 filter is reserved for the broadcast address.
You can install and configure the Cisco uBR904 to operate as a router. In routing mode, no maximum upper limitation exists. For instructions to change from bridging to routing modem, see the "Important Notes" section of this document.
 | Caution After you connect a laptop PC to the Cisco uBR904 console port and save configuration changes (provided your network supports remote configuration) power cycle the Cisco uBR904 if you're not using the laptop at the subscriber site. This is important when the Cisco uBR904 is configured to operate in a DOCSIS-compliant bridging mode. Power cycling the Cisco uBR904 ensures the laptop PC does not remain in the list of CPE devices at the subscriber site for the Cisco uBR904 to support. Only reinitialization of the cable interface clears out the bridge table and resets the counter that specifies the number of CPE devices being bridged. |
The current implementation of L2TP in Cisco IOS Release 12.0(5)T is dependent on a PPP connection supported on one of the directly attached interfaces. A dial-up PPP connection is required in order to initiate an L2TP Tunnel connection. This is a requirement of the L2TP Access Concentrator (LAC). In Cisco IOS Release 12.0(5)T, the Cisco uBR904 cable access router cannot function as the LAC; it can only function as the L2TP Network Server (LNS), which terminates a tunnel created elsewhere in the network.
This section contains important information about using your Cisco IOS Release 12.0 T software.
Data transmitted to a Cisco uBR904 cable access router from the CMTS shares a 27 or 26 Mbps, 6 MHz data channel in the 88 to 860 MHz range. The Cisco uBR904 shares an upstream data rate of up to 10 Mbps on a 200kHz-wide to 3.2 MHz-wide channel in the 5 to 42 MHz range.
The Cisco uBR904 cable access router supports 64 or 256 Quadrature Amplitude Modulation (QAM) downstream, and Quadrature Phase Shift Keying (QPSK) or 16 QAM upstream transmission.
| Description | Downstream Values | Upstream Values |
|---|---|---|
Frequency Range | 88 to 860 MHz | 5 to 42 MHz |
Modulation | 64 QAM | QPSK |
Data Rate | 30 Mbps/64 QAM | QPSK---320 Kbit/sec to 5 Mbit/sec |
Bandwidth | 6 MHz | 200K, 400K, 800K, 1.6M, 3.2 MHz |
FEC | RS (122, 128) Trellis | Reed Solomon |
One Channel | Receive level of digital signal | QPSK--- +8 to +58 dBmV |
Signal-to-Noise Ratio (SNR) | 64 QAM: | QPSK: |
Security | DES decryption: DOCSIS Baseline Privacy (BPI), 40 bit- and 56 bit-encryption, as controlled by the headend and configuration files. Note Cisco IOS images must contain encryption software at both the CMTS and the Cisco uBR904. Enable and configure both routers to support encryption. | DES encryption. |
DOCSIS configuration files are created at the headend typically by using a configuration file editor of your choice. Using the FastStep utility at a subscriber site to locally configure the unit is not supported.
The DOCSIS configuration file defines the Cisco uBR904's operating mode, such as the provisioned downstream and upstream service assignments, including assigned frequencies, data rates, modulation schemes, Class of Service (CoS), type of services to support, and other parameters.
The Cisco uBR904 cable access router supports the following service classes:
| Step | Command | Purpose | ||
|---|---|---|---|---|
| uBR904(config)#int c 0 | Enter the interface configuration mode for the router interface. | ||
| uBR904(config-if)#no cable-modem compliant bridge uBR904(config-if)#no bridge group number and remove bridge-group number. uBR904(config-if)#ip address mask ip address x.x.x.x (0-255) subnet mask x.x.x.x (0-255) uBR904(config-if)#exit | Turn off DOCSIS-compliant bridging.
Return to the global configuration mode. | ||
| uBR904(config)#int e 0 uBR904(config-if)#no bridge group number and remove bridge-group number. uBR904(config-if)#ip address mask ip address x.x.x.x (0-255) subnet mask x.x.x.x (0-255) uBR904(config-if)#exit | Enter the interface configuration mode for Ethernet 0.
Return to the global configuration mode. | ||
| uBR904(config)#ip routing | Enable IP routing for the router. | ||
| uBR904(config)#router rip uBR904(config)#version 2 rip uBR904(config)#network network-number uBR904(config-if)#exit | Enter the router configuration mode and enable RIP version 2 routing. Specify the network that is connected to the router where RIP will operate. If the router is attached to more than one network, enter each IP address in a separate command. Return to the global configuration mode. | ||
| uBR904(config-if)#Ctrl-z | Return to the privileged EXEC mode. |
Normally, the CMTS system administrator uses the provisioning and billing system to set the software upgrade file name, the IP address of the TFTP server where the software upgrade file exists, and the MAC address of the Cisco uBR904 to upgrade in the field. Refer to the procedure that follows.
Option 128 in the DOCSIS configuration file supports a vendor-defined attribute (type = 43) that lets the system administrator define the name of a Cisco IOS image to download to a remote Cisco uBR904. This requires a unique DHCP policy for the Cisco uBR904, a unique DOCSIS configuration file to be sent by the DOCSIS process, and a unique Cisco IOS image file name---such as "ios.cfg" file---located in the same TFTP server directory supported by the DOCSIS process.
When the Cisco uBR904 initializes, Cisco IOS software processes the DOCSIS configuration file. If the software upgrade option is present in the DOCSIS configuration file and if the name of the Cisco IOS image in the DOCSIS configuration file differs from the image that is currently running on the Cisco uBR904, the router downloads the new Cisco IOS image from the TFTP server and automatically reboots.
To download an updated Cisco IOS image via a DOCSIS configuration file:
Step 1 Create a file to send to the remote Cisco uBR904 by using a configuration file editor of your choice. In that file, specify commands such as:
Step 2 Save the file by using a short name such as "ios.cf".
Step 3 Ensure that file permissions allow the file to be sent by TFTP.
Step 4 Start an Internet browser, such as NetScape 4.08 and create a generic DOCSIS configuration file by using the Cisco configuration file editor of your choice. Cisco provides a number of tools to help automate this process.
Step 5 Follow the instructions provided in the specific Cisco tool. Select the starting point for your configuration file, for example, bronze.cm, silver.cm, gold.cm, platinum.cm. This populates the configuration file with default provisioning values.
Correctly populate the following two fields:
To download a specific Cisco IOS image to a group of Cisco uBR904s, you can define an Organizationally Unique Identifier (OUI) and use this OUI to make the Cisco uBR904s pay attention to the Vendor ID and VSIF. A global OUI can be used---"0-0-c".
(a) To install a file called "Cisco ios.cf" on ten Cisco uBR904s, (assuming a mixture of OUIs exist on those ten units such as "00-50-7b", "00-10-7d", and so on) use the configuration file editor of your choice and specify "0-0-c" in the Vendor ID field.
(b) Tell the Cisco uBR904s that they must get the file called "ios.cf" through TFTP. You do this with the VSIF field. Calculate the "dotted-decimal" equivalent of the ASCII characters: i o s . c f
Use a Sun workstation or any UNIX box and enter:
unix-workstation%man ascii
This prints out the man page. You can find the ASCII-to-decimal conversion chart needed. See the sample below:

|120 x |121 y |122 z |123 { |124 | |125 } |126 ~ |127 DEL|
(c) By using a similar chart as that above, convert the "ios.cf" string letter-by-letter to a decimal value. Here is what you end up with:
i o s . c f 105 111 115 46 99 102
(d) Populate the VSIF field of the DOCSIS configuration file by using the editor of your choice.
(e) Save your changes by using the configuration file editor of your choice. Change the "File Name" field selected in Step 5: for example, bronze.cm, silver.cm, gold.cm, platinum.cm, to a different value such as:
/tftpboot/gold-ios-config.cm
(f) Once you have saved the file as "gold-ios-config.cm," then, FTP back to cs and log in. Make sure you use the binary mode of FTP and choose the file you just created.
(g) Put the file in the /tftpboot (or equivalent) directory of the TFTP server you are using for your Cisco uBR904 setup. Enter the following command to ensure you can TFTP the file:
chmod 777 gold-ios-config.cm
(h) Go into your DHCP server by using a Cisco tool such as CNR and change the value for "packet-file-name" to the new file name you just created: "gold-ios-config.cm."
(i) Once you have reloaded the CNR DHCP server or the tool you are using, enter the following command from the CMTS:
clear cable modem x.x.x.x reset
The Cisco uBR904 reregisters with the CMTS. When it gets the new DOCSIS configuration file---"gold-ios-config.cm"---it TFTPs the file "ios.cf" to itself.
The console port of the Cisco uBR904 is completely disabled.
|
If you entered passwords for enable and vty, you should see something similar to the example shown below when you telnet to the Cisco uBR904:
UBR7246# telnet 10.1.1.255 Trying 10.1.1.255 ... Open SUCCEED line 1 User Access Verification Password: SUCCEED>en Password: SUCCEED#
You should see the value of the "hostname" command you put in the ios.cf file now installed on the Cisco uBR904; and all other commands.
If you enter show version on the Cisco uBR904, the Cisco uBR904 indicates a "HOST CONFIGURATION FILE" has been loaded by using TFTP in the middle of the output. Look at the last line of the example below:
System restarted by power-on at 20:23:35 - Tue Jun 15 1999 System image file is "flash:ubr900-y4-mz.113-9.NA", booted via flash Host configuration file is "ios.cf", booted via tftp from 207.249.162.170
You have successfully loaded the Cisco IOS image and DOCSIS configuration file.
Older Cisco Management Information Bases (MIBs) will be replaced in a future release. OLD-CISCO-* MIBs are currently migrated into more scalable MIBs---without affecting existing Cisco IOS products or NMS applications. You can update from deprecated MIBs to the replacement MIBs as shown in Table 6.

The Cisco IOS software documentation set consists of the Cisco IOS configuration guides, Cisco IOS command references, and several other supporting documents, which are shipped with your order in electronic form on the Documentation CD-ROM---unless you specifically ordered the printed versions.
Each module in the Cisco IOS documentation set consists of two books: a configuration guide and a corresponding command reference. Chapters in a configuration guide describe protocols, configuration tasks, and Cisco IOS software functionality and contain comprehensive configuration examples. Chapters in a command reference provide complete command syntax information. Each configuration guide can be used in conjunction with its corresponding command reference.
On CCO and the Documentation CD-ROM, two master hot-linked documents provide information for the Cisco IOS software documentation set.
