Introduction

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 cable operator's headend facility or distribution hub and to 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-based cable modems (CMs) and set-top boxes (STBs).

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.

Note   The Cisco IOS Release 12.0 SC software supports only two-way, DOCSIS-based cable modems and set-top box (STB) units with integrated DOCSIS modems. The SC release excludes support of the clock card in the Cisco uBR7246 VXR. The SC release also excludes DOCSIS 1.0 extension support, as well as 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 Cisco uBR7200 series routers support 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. Additional protocols and media may be added as they become available for the Cisco uBR7200 series routers.

For information on new features and Cisco IOS commands supported by Cisco IOS Release 12.0(15)SC, see the "New and Changed Information" section on page 13 and the "Related Documentation" section on page 58.

Cisco IOS Release 12.0(15)SC1 supports the Cisco uBR7246 VXR, Cisco uBR7246, and Cisco uBR7223.

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.

lists only the cable-specific features and feature sets, with the exception of Management Information Bases (MIBs), supported by the Cisco uBR7200 series in Cisco IOS Release 12.0 SC1 and uses the following conventions:

•Yes—The feature is supported in the software image.

•No—The feature is not supported in the software image.

•In—The Cisco IOS release that first introduced a feature. For example, (6) means a feature was introduced in 12.0(6)SC, and (10) means a feature was first introduced in 12.0(10)SC. If a cell is empty in this column, the feature was included in the initial base release.

Note This feature set table only contains a selected list of features. This table is not cumulative, nor does it list all the features in each image. Features that are not listed are in all images.You can find the most current Cisco IOS documentation on Cisco.com. This set of electronic documents may contain updates and modifications made after the hard-copy documents were printed. If you have a Cisco.com login account, you can find image and release information regarding features prior to Cisco IOS Release 12.0(15)SC1 by using the Feature Navigator tool at: http://www.cisco.com/go/fn.

No New Hardware Features in Release 12.0(13)SC

There are no new hardware features supported by the Cisco uBR7200 series routers in Cisco IOS Release 12.0(13)SC.

New Software Features in Release 12.0(13)SC

The following CLI and MIB enhancements are supported by the Cisco uBR7200 series routers in Cisco IOS Release 12.0(13)SC.

Cable Downstream Frequency Override CLI

The following new CLI command turns off the cable downstream frequency override on a per-interface basis:

[no] cable downstream override

The default configuration enables the cable downstream frequency override. Only the [no] cable downstream override command is displayed and allows the cable downstream frequency override to be turned off.

Enhancements for the "cdxCmtsCmOnOffTrapEnable" Object

The following new CLI commands are supported for the "cdxCmtsCmOnOffTrapEnable" object:
[no] cable enable-trap cmonoff-notification
[no] cable enable-trap cmonoff-interval < time 0 to 86400 >

These commands have the following default settings:
no cable enable-trap cmonoff-notification
no cable enable-trap cmonoff-interval

After the default setting has been changed and the new configuration has been saved, the new configuration will remain active after the CMTS reloads.

Syntax examples:

•cable enable-trap cmonoff-notification—This command enables "cdxCmtsCmOnOffNotification" in the RF MAC interface. Alternatively, the user can set the SNMP object "cdxCmtsCmOnOffTrapEnable" to true (1).

•no cable enable-trap cmonoff-notification—This command disables "cdxCmtsCmOnOffNotification" in the RF MAC interface. Alternatively, the user can set the SNMP object "cdxCmtsCmOnOffTrapEnable" to false (2).

•cable enable-trap cmonoff-interval <time 0 to 86400>—This command sets the interval for "cdxCmtsCmOnOffNotification" sent by the CMTS for one online/offline CM state change when "cdxCmtsCmOnOffTrapEnable" is set to true (1). Alternatively, the user can set the SNMP object "cdxCmtsCmOnOffTrapInterval" to the same time value.

•no cable enable-trap cmonoff-interval—This command sets the interval "cdxCmtsCmOnOffNotification" to 0 so that "cdxCmtsCmOnOffNotification" will be sent for every online/offline CM state change when "cdxCmtsCmOnOffTrapEnable" is set to true (1). Alternatively, the user can set the SNMP object "cdxCmtsCmOnOffTrapInterval" to 0.

Note The default for "cdxCmtsCmOnOffTrapInterval" is 0.

Enhancements for DOCS-IF-MIB

For an MC16E cable modem card in ANNEX-A mode, DOCS-IF-MIB is compliant with Euro-DOCSIS; for any other cable modem card (that is, any "non-E" cable modem card), DOCS-IF-MIB is compliant with DOCSIS.

The "docsIfUpChannelFrequency" object now shows the actual frequency (instead of the configured frequency) for an Euro-DOCSIS-compliant cable modem card, while it shows the configured frequency for a DOCSIS-compliant cable modem card.

The following new CLI command allows the default-compliancy mode (that is, actual frequency for Euro-DOCSIS or configured frequency for DOCSIS) of the "docsIfUpChannelFrequency" object to be changed:

test cable docs-if-mib [show | change option-code]

In this command, show indicates the current compliancy-mode, while change option-code can have a value of 1, 2, or 3:

•test cable docs-if-mib 1 sets the compliancy-mode to default

•test cable docs-if-mib 2 sets the compliancy-mode to DOCSIS (independent from the cable modem card)

•test cable docs-if-mib 3 sets the compliancy-mode to Euro-DOCSIS (independent from the cable modem card)

No New Hardware Features in Release 12.0(12)SC

There are no new hardware features supported by the Cisco uBR7200 series routers in Cisco IOS Release 12.0(12)SC.

New Software Features in Release 12.0(12)SC

The following MIB enhancements are supported by the Cisco uBR7200 series routers in Cisco IOS Release 12.0(12)SC.

MIB Enhancements

Prior to Release 12.0(12)SC, DOC-IF-MIB was only DOCSIS-compliant. Release 12.0(12)SC adds Euro-DOCSIS compliancy to DOCS-IF-MIB.

For an MC16E cable modem card in ANNEX A mode, DOCS-IF-MIB is compliant with Euro-DOCSIS; for any other cable modem card (that is, any "non-E" cable modem card), DOCS-IF-MIB is compliant with DOCSIS.

No New Hardware Features in Release 12.0(11)SC

There are no new hardware features supported by the Cisco uBR7200 series routers in Cisco IOS Release 12.0(11)SC.

New Software Features in Release 12.0(11)SC

The following new software features are supported by the Cisco uBR7200 series routers in Cisco IOS Release 12.0(11)SC.

Multicast BPI MIB Support

Because a multicast Service Identifier (SID) on CMTS will not be determined until the CMTS receives an Internet Group Management Protocol (IGMP) join request from a host, there are some limitations that apply to "docsBpiIpMulticastServiceId" and "docsBpiMulticastServiceId":

•docsBpiIpMulticastServiceId

•It is read-only.

•Zero is its value when no (SID) is assigned to it.

•Zero is its value when its sibling "docsBpiIpMulticastPrefixLength" is less than 32.

•docsBpiMulticastServiceId

•Value must derive from multicast SIDs created when the CMTS handled IGMP join requests.

Support for RFC2233 LinkUp/Down Traps

The objects in the varbind list based on the Internet Engineering Task Force (IETF) standard are defined in IF-MIB. Since IF-MIB supports subinterfaces, all objects in this varbind list are also supported for subinterfaces. The feature allows the user to specify the LinkUp/Down trap varbind list to be based on a Cisco-specific or IETF standard with a new command line interface (CLI) configuration command:
snmp-server link-trap [cisco | ietf]
The default is a Cisco-specific link trap (snmp-server link-trap cisco). The user can switch between Cisco and IETF standard.

SNMP Objects for Clear Host, Clear Cable Modem, and Show Current CPEs

Clearing host or cable modems (CMs) can be done via "cdxCmCpeResetNow" MIB object. Displaying the number of current CPEs can be done via "cdxCmtsCmCurrCpeNumber" MIB object.

No New Hardware Features in Release 12.0(10)SC1

There are no new hardware features supported by the Cisco uBR7200 series routers in Cisco IOS Release 12.0(10)SC1.

No New Software Features in Release 12.0(10)SC1

There are no new software features supported by the Cisco uBR7200 series routers in Cisco IOS Release 12.0(10)SC1.

No New Hardware Features in Release 12.0(10)SC

There are no new hardware features supported by the Cisco uBR7200 series routers in Cisco IOS Release 12.0(10)SC.

New Software Features in Release 12.0(10)SC

The following new software features are supported by the Cisco uBR7200 series routers in Cisco IOS Release 12.0(10)SC.

Secure Shell (SSH) Supported in "k1" Images for Cisco uBR7200

In Cisco IOS Release 12.1 T, the definition of "k1" images for Cisco uBR924 cable access routers was changed from support for BPI only, to also include support for Secure Shell (SSH). This change caused an inconsistency with Cisco uBR7200 series images, since the definition of "k1" for the Cisco uBR7200 was not changed and did not include SSH.

In Cisco IOS Release 12.0(10)SC, the Cisco uBR7200 series "k1" images now support SSH.

Cisco uBR7200 series universal broadband routers support the Cisco IOS Firewall feature. This feature set offers Network Address Translation (NAT) and is designed to prevent unauthorized, external access to your internal network, blocking attacks on your network, while still allowing authorized users to access network resources. This feature is described in detail in the Cisco IOS Firewall Feature Set feature module, available on Cisco.com and the Documentation CD-ROM. As of Cisco IOS Release 12.0(10)SC, SSH is a part of the Cisco IOS Firewall feature set.

No New Hardware Features in Release 12.0(9)SC

There are no new hardware features supported by the Cisco uBR7200 series routers in Cisco IOS Release 12.0(9)SC.

New Software Features in Release 12.0(9)SC

The following new software features are supported by the Cisco uBR7200 series routers in Cisco IOS Release 12.0(9)SC.

Dynamic Mobile Hosts

When an existing cable modem is swapped with a new one, such as a field replacement, the Media Access Control (MAC) address for the PC will be associated with the old cable modem. This could also happen if a PC is moved from one cable modem to another.

This feature allows the CMTS administrator to bring up a PC behind one CM, then move it to another CM. Software adds information for the hosts involved in host tables. To prevent security breaches, the software supports pinging the host using the old SID to verify that it has indeed been moved.

DHCP server is used to verify addresses and can be configured with the cable source-verify dhcp command; the no cable arp command should be configured in the CMTS to prevent it from sending ARP requests.

Support DOCSIS OSSI Required Objects in RFC 2665 for Cisco uBR7200 Series Routers

Cisco uBR7200 series routers support the required objects in RFC 2665 for DOCSIS Operations Support System Interface (OSSI) compliance now.

•A new MIB file ETHERLIKE-MIB.my that matches RFC 2665 is added.

•The following new objects are now supported in ETHERLIKE-MIB:

•dot3StatsSymbolErrors

•dot3StatsDuplexStatus

•Two new tables in RFC2665 are not yet supported:

•dot3ControlTable

•dot3PauseTable

•Also, "dot3CollTable" is not yet supported.

Support DOCSIS OSSI Required Objects in RFC 2233 for Cisco uBR7200 Series Routers

Cisco uBR7200 series routers support the required objects in RFC 2233 for DOCSIS OSSI compliance now.

•IF-MIB.my is updated to match RFC 2233.

•The following new object is now supported:

•ifCounterDiscontinuityTime
