Introduction

For information on new features and Cisco IOS commands supported by Cisco IOS Release 12.2(2)XF1, see the "New and Changed Information" section and the "Related Documentation" section.

Cisco IOS Release 12.2(2)XF1 supports the Cisco uBR10012 universal broadband router, which provides a high-capacity, high-throughput cable modem termination system (CMTS), optimized for aggregating traffic at the edge of the cable network. Designed for cable operators and service providers, the platform connects residential subscribers via cable modems, digital set-top boxes, or IP telephony cable modems for high-speed data, broadband entertainment, and IP telephony solutions.

The Cisco uBR10012 router has been designed as a high-capacity platform that places a new level of intelligence at the edge of the network, enabling cable service providers to maximize their revenues by delivering more feature-rich services to their customers. The Cisco uBR10012 router uses the industry-proven Parallel eXpress Forwarding (PXF) technology, derived from the Cisco ESR10000 Edge Services Router, to provide consistent, high-performance throughput, even as software features are added and additional services are deployed.

In addition, it supports a variety of broadband access technologies, including Data-over-Cable Service Interface Specification (DOCSIS), gigabit ethernet, and optical. With support for multiple standards, operators can choose the appropriate services and devices to optimize their capital investment with a single CMTS platform. With access to current and future software enhancements, the Cisco uBR10012 also ensures investment protection as standards and customer needs continue to evolve.

Cable companies and Internet service providers (ISPs) can allocate radio frequency (RF) channel capacity for Internet access or high priority services using a hybrid fiber/coax (HFC) or an all-coax cable plant. Cisco currently provides two router-based DOCSIS CMTS solutions that offer a wider feature set and better manageability than bridge-based systems.

The Cisco uBR10012 Universal Broadband Router

The Cisco uBR10012 universal broadband router brings the powerful performance and proven reliability of the industry-leading, DOCSIS-qualified Cisco uBR7200 series universal broadband router product line to the next level of performance, capacity, and throughput. The Cisco uBR10012 platform provides a complete, easy-to-use, integrated router and cable modem termination system (CMTS) package, with feature-rich software and unparalleled customer service and support. With access to current and future software enhancements, the Cisco uBR10012 routers also ensure investment protection as standards evolve.

The Cisco uBR10012 router supports up to eight cable interface line cards. Cisco IOS Release 12.2(2)XF1 supports the Cisco uBR-LCP-MC28C line card, based on the existing Cisco uBR-MC28C line card, with two downstreams and eight upstreams divided into two domains. This provides the ability to support a large volume of cable modem subscribers using only one chassis.


Note The Cisco uBR10012 router supports both the Cisco uBR-LCP-MC28C line card (which uses F-connectors) and the Cisco uBR-LCP-MC28C-BNC (which uses BNC connectors). Unless otherwise indicated, all references to the Cisco uBR-LCP-MC28C refer to both versions of the card.


For connection to the Internet and other networks, the Cisco uBR10012 router supports up to four network uplink line cards, each of which can support connections as fast as 1Gb/s (Gigabit Ethernet). Cisco IOS Release 12.2(2)XF1 supports OC-12 POS and Gigabit Ethernet connectivity.


Note This guide focuses on Cisco uBR10012 software. For detailed descriptions of the Cisco uBR10012 router chassis and components, see the hardware documents listed in the "Related Documentation" section.


Cisco uBR10012 Router Cable Interface

The cable interface in the Cisco uBR10012 router serves as the RF cable TV interface, supporting downstream and upstream signals. The downstream is output as an IF signal suitable for use with an external upconverter. Your cable plant, combined with your planned and installed subscriber base, service offering, and external network connections, determines what combination of Cisco uBR10012 cable interfaces, network uplink line cards, and other components that you should use.

Early Deployment Releases

These release notes describe the Cisco uBR10012 universal broadband router for Cisco IOS Release 12.2(2)XF1. Release 12.2 XF s an early deployment (ED) release based on Release 12.2 T, which serves as the train's starting point. Early deployment releases contain fixes to software caveats as well as support for new Cisco hardware and software features. Feature support is cumulative from release to release, unless otherwise noted.

Important Notes

The following sections contain important notes about Cisco IOS Release 12.2(2)XF1 that apply to the Cisco uBR10012 universal broadband router.

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 traps 
router(config)# no snmp-server enable traps syslog 

Cable Monitor is Not Supported

Cisco IOS Release 12.2(2)XF1 does not support the cable monitor command.

Configuring the Routing Protocol Causes a Reset of the Cable Modems

Be aware that when configuring a routing protocol on an interface, the Cisco IOS software must reset the interface 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 interface configuration commands, such as router rip, on a cable interface only when a minimum of subscribers would be affected.

Redundant PRE Modules Are Not Supported

Cisco IOS Release 12.2(2)XF1 does not support Route Processor Redundancy (RPR) for the Performance Routing Engine (PRE) cards. Although two PRE modules can be installed in a Cisco uBR10012 chassis, Cisco does not guarantee that upon a failure of the primary PRE module in Cisco IOS Release 12.2(2)XF1, the redundant PRE module can automatically bring up all DOCSIS cable interface line cards.

Web Cache Communication Protocol Is Not Supported

The Cisco uBR10012 router does not support the Web Cache Communication Protocol (WCCP) feature set in Cisco IOS Release 12.2(2)XF.

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 uBR10012 universal broadband router supports 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 router, 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 Cisco uBR10012 router. They include both DOCSIS-specific MIBs and Cisco-specific enterprise MIBs. If your network management applications have not already been configured for the Cisco uBR10012 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.

CISCO-ENTITY-VENDORTYPE-OID-MIB

The cable-specific MIBs are described in the following section. 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.

Cable-Specific MIBs

Table 5 shows the cable-specific MIBs that are supported on the Cisco uBR10012 universal broadband router. 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 5 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/sw-center/netmgmt/cmtk/mibs.shtml). Most MIBs are available in both SNMPv1 and SNMPv2 versions; the SNMPv1 versions have V1SMI as part of their filenames.

All the caveats listed in Table 7 are open in Cisco IOS Release 12.2(2)XF1. This table lists only severity 1 and 2 caveats and select severity 3 caveats.

Table 7 Open Caveats for Release 12.2(2)XF1 

Caveat ID Number
Description

CSCdu15467

PRE Redundancy: Modems go offline during failover.

CSCdv02247

The Cisco uBR10012 router does not support the cable modem change-frequency, cable modem max-hosts, and cable modem qos commands.

CSCdv17163

Under rare circumstances, a GigE line card link can go down after a PRE reload. Possible workarounds are to reenable the interface using the shutdown and no shutdown commands, or to not use autonegotiation on the link.

CSCdv17552

The cable interface line card can crash at bootup with the following message: %CRYPTO-0-SELF_TEST_FAILURE: Encryption self-test failed.

CSCdv36206

When a cable interface line card is under severe load, the card might generate the following error message and reload: "ipc_send_message_blocked timed_out (Cause: timeout)". The workaround is to reduce the number of cable modems on the line card.

CSCdv54518

Fast-switching on the cable interface does not work. Possible workarounds are to enable CEF on the incoming (backhaul) interface or to disable fast-switching on the outgoing cable interface.


Closed and Resolved Caveats for Release 12.2(2)XF1

CSCdu83820

In rare situations during the bootup sequence, SYS-2-BADSGARE error messages could appear on the console.

CSCdv14807

Packets can be dropped when the OC-12 POS line card is pinged. The problem occurs when one end of the POS connection has keepalive messages enabled and the other end does not. The workaround is to configure both ends of the OC-12 POS connection with the same keepalive configuration.

CSCdv46210

The Line Card Processor could crash in certain situations when HCCP is enabled and the cable interface is shutdown for a switchover.

CSCdv54522

The Cisco uBR10012 software could encounter memory leaks when SNMP is enabled. There is no workaround.
