Purpose

This guide describes the procedures necessary to configure, maintain, and troubleshoot the initial software configuration for the Cisco uBR10012 universal broadband router. This guide also directs you to other closely related documentation for additional features and optimization.

The Cisco uBR10000 series CMTS solutions allow cable companies, Internet service providers (ISPs), and others to allocate channel capacity for Internet access services using a broadband radio frequency (RF) cable plant. The Cisco uBR10012 router sustains two-way downstream and upstream traffic over Data-over-Cable Service Interface Specifications (DOCSIS)-based cable modems (CMs) that support 6 MHz National Television Systems Committee (NTSC) operations.

Audience

This guide is intended for system administrators and support engineers who configure and maintain the Cisco uBR10012 router. Many different delivery models exist for Cisco uBR10000 series equipment:

In smaller networks, a single service provider manages all equipment and infrastructure.

In larger networks, multiple service operators (MSOs) and ISPs share responsibility for provisioning and managing the cable plant and IP network.

How the MSO and ISP divide responsibilities depends on the service model. In some cases, the MSO maintains and operates the cable plant and attached CMs and set-top boxes (STBs), and the ISP owns, operates, and maintains the regional network and IP infrastructure beyond the cable distribution hub. In other cases, the Cable Modem Termination System (CMTS) and RF customer premises equipment (CPE) are viewed as part of the networking infrastructure, and the ISP maintains control for provisioning and managing DOCSIS functionality.


Note This guide considers the MSO and ISP as a single service principle with responsibility to provision and manage DOCSIS-based cable modems and STBs. This guide assumes that administrators are familiar with Cisco uBR10000 series hardware, DOCSIS requirements, and networking.


Document Organization

This guide focuses on configuration of Cisco IOS software for the Cisco uBR10012 router. Table 2 summarizes the chapters and procedures in this guide. These chapters are presented in the general sequence used in a router installation and configuration. However, this sequence is also affected by your network configuration and other factors.

MIBs

The Cisco uBR10012 router supports the following categories of Management Information Bases (MIBs):

Cable-specific MIBs—Provide information about the cable interfaces and related information on the Cisco uBR10012 router. They include both Data-over-Cable Service Interface Specifications (DOCSIS)-specific MIBs and enterprise MIBs specific to Cisco. If your network management applications have not already been configured for the Cisco uBR10012 router, these MIBs must be loaded. The Cisco uBR10012 router and CMTS supports DOCSIS 1.1 MIBs.

The Cisco uBR10012 router supports objects related to QoS support for scheduler of DOCSIS-compliant RF interfaces in the CMTS.

Cisco platform and network-layer enterprise MIBs—Common across most Cisco router platforms. If your network management applications are already configured to support other Cisco routers, such as the Cisco 2600 series router, no further configuration is needed unless the version of Cisco IOS software being used has updated these MIBs.

Simple Network Management Protocol (SNMP) standard MIBs—These MIBs are required by any agent supporting SNMPv1 or SNMPv2 network management. The SNMP MIBs improve object support for SNMP traps. This aids in network management. Traps are the mechanisms used to automatically send alarms for certain network events.

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.

Technical Assistance Center

The Cisco TAC is available to all customers who need technical assistance with a Cisco product, technology, or solution. Two types of support are available through the Cisco TAC:

the Cisco TAC Web site


Note In addition, be sure to familiarize yourself with TAC's Cisco uBR10012 Product Support Page at http://www.cisco.com/cisco/web/support/index.html.


the Cisco TAC Escalation Center

Inquiries to Cisco TAC are categorized according to the urgency of the issue:

Priority level 4 (P4)—You need information or assistance concerning Cisco product capabilities, product installation, or basic product configuration.

Priority level 3 (P3)—Your network performance is degraded. Network functionality is noticeably impaired, but most business operations continue.

Priority level 2 (P2)—Your production network is severely degraded, affecting significant aspects of business operations. No workaround is available.

Priority level 1 (P1)—Your production network is down, and a critical impact to business operations will occur if service is not restored quickly. No workaround is available.

Which Cisco TAC resource you choose is based on the priority of the problem and the conditions of service contracts, when applicable.

Cisco TAC Web Site

The Cisco TAC Web site allows you to resolve P3 and P4 issues yourself, saving both cost and time. The site provides around-the-clock access to online tools, knowledge bases, and software. To access the Cisco TAC Web site, go to the following URL:

http://tools.cisco.com/ServiceRequestTool/create/launch.do

All customers, partners, and resellers who have a valid Cisco services contract have complete access to the technical support resources on the Cisco TAC Web site. The Cisco TAC Web site requires a Cisco.com login ID and password. If you have a valid service contract but do not have a login ID or password, go to the following URL to register:

https://tools.cisco.com/RPF/register/register.do

If you cannot resolve your technical issues by using the Cisco TAC Web site, and you are a Cisco.com registered user, you can open a case online by using the TAC Case Open tool at the following URL:

http://tools.cisco.com/ServiceRequestTool/create/launch.do

If you have Internet access, it is recommended that you open P3 and P4 cases through the Cisco TAC Web site.

Cisco TAC Escalation Center

The Cisco TAC Escalation Center addresses issues that are classified as priority level 1 or priority level 2; these classifications are assigned when severe network degradation significantly impacts business operations. When you contact the TAC Escalation Center with a P1 or P2 problem, a Cisco TAC engineer will automatically open a case.

To obtain a directory of toll-free Cisco TAC telephone numbers for your country, go to the following URL:
